Flex Circuit Board Introduction & PCB Types
Flex Circuit Board Introduction & PCB Types
A printed circuit board supports and connects electrical components using conductive tracks and pads from copper sheet which are laminated between sheet layers of a non conductive substrate.About flex circuit boardThe flex circuit board offers multiple possibilities for different types of products and designs. These circuit boards help you to find your favourite TV channels and adjust the volume in the remote. They are thin and light weighted circuits. They are the replacements for the traditional ones. They help the electronic goods to be lighter and smaller when they design it. This will help them to make hassle free movements.Different types of Printed Circuit BoardsSingle sided Printed Circuit Board: These types of flex circuit board contain just one layer of base material. This base material is covered with a thin layer of metal usually copper as it has an excellent electrical conductor. It has an electronic component and a circuit on one side only. They are best for simple electronics. They are inexpensive and because of the design specifications, these circuit boards also used in special purposes.Double sided Printed Circuit Board: Both the sides of these circuit board have metal conductive layer. The holes in this circuit board allow circuit on one side to connect the circuit on the other side. The double sided circuit board uses two methods for connecting them which are through hole technology and through surface mount technology. Through hole technology involves feeding tiny wires through the holes and soldering each of them to the circuit. In surface mounted technology, wires are not used. They allows more circuit to be made in a smaller space on a board which means the board can perform more functions usually at a lower rate and faster speed.Multi layered Printed Circuit Board: This is also extension of double sided circuit board. They have several base layers and insulating materials separating the base layers. They saves even more space compared to the double sided. This multi layered board has different layers such as 4, 6, 8, and 10 depending on the demand of the product. They are generally used in computers or medical machinery or servers, etc.Rigid Printed Circuit Board: They use a solid, inflexible base layers that keep the board from bending. A motherboard inside the computer is a best example of rigid printed circuit boards. Flex- Printed Circuit Board: The base here is a flexible one. The materials allow the board to fit into shape that rigid boards cannot without damaging the circuit of the board. They can be single sided, double sided or multi layered. Rigid- flex Printed Circuit Board: These board combine technology from both rigid and flexible circuit boards. A simple rigid flex circuit board comprises of rigid circuit boards that are attached to a flex circuit board.ApplicationsPrinted Circuit Board is used in computer,cameras, cell phones, bar code equipments, avionics, satellites, etc. If you want them for a specific task, it is always better to get them from the leading manufacturers.Resource: RELATED QUESTION What can I do as a small printing company nowadays? This is a tough question, because the printing industry has changed drastically over the past several decades. Lawrence Finn noted the range of things that a small printing shop usually does, but unfortunately even those are on their way out. And in cases where they are still around, mass-market shops with economies of scale (such as FedEx Office) can typically do anything you can do, faster and cheaperand include online ordering and previewing, etc. So the real issue comes down to what special things you can do that they cant. The closest to your current operation might be (talk about back to the future, or, more accurately, forward to the past) to get a letterpress and start doing custom, high-end work such as wedding invitations and letterhead. The equipment isnt crazy expensive, the market is not insanely expensive, and you can transfer much of what you already know. You can get a new high-speed digital press and offer large scale custom commercial printing. You can get new equipment and specialize in die cutting and embossing, and perhaps form mutual referral partnerships with local folks who do flat printing. You can get new screen printing equipment and specialize in t-shirts and the likebut thats a very different business, and already somewhat competitive. You can get new flexographic printing equipment and print small productsbut thats got the same problems of a new business with existing competition. You might try getting a laser engraver and doing on-the-spot engraving and customization (my guess is that this might be your best option, but probably only as an add-on service). You could get a number of 3D printers and offer that as a service, along with design. You could specialize as an integrated online/offline shop, combining web work, business cards, etc. with the emphasis on design, leaving the production to a larger firm like VistaPrint . Whatever you do, I wish you the best of luck integrating printing into the 21st century!

Quality Printed Circuit Board Materials That Fix Your Requirements
Quality Printed Circuit Board Materials That Fix Your Requirements
For your perfect PCB, you will require some knowledge of the materials that make up a PCB. Armed with this knowledge you can decide, depending on your budget, which material would be best to suit your requirements. The circuit board foundation or the base is comprised of the substrate and the laminate. Usually, the substrate is a non-conductive dielectric material that is chosen based on the dielectric constant. Laminates are used in with substrates to provide a surface material or copper foil. Laminates themselves, however, can be used as the core material in certain board constructions. For these purposes, using flex printed circuits are a good investment. There are plenty of Flex PCB Manufacturers that would be willing to get the job done on short notice. Flexible substrates are a new and upcoming material that is being used in most new printed board circuits. They are primarily made up of copper. A good Flex PCB Manufacturer will be able to provide everything mentioned below. This article will elaborate on flex a little later once you understand the basics of substrates and laminates and what they require.SubstratesThese are the dielectric composite structures that are made up of paper or glass weave and epoxy resin. These can be supplemented by ceramics to further increase the dielectric constant. Substrates are created for meeting specific property requirements, like a higher melting point, and it also needs to be able to be customized accordingly.There are a large range of standard substrates, however, from which most of the PCB manufactured are created. Some examples of these substrates are CEM-1 through CEM-5, FR-1 through FR-6, G-10 and G11, Polytetrafluoroethylene, Aluminum or insulated metal substrate, RF-35 Alumina, Polymide and the flexible substrates of Pyralux and Kapton. FR-4 is the most commonly used substrate.LaminatesLaminates are those materials manufactured under pressure and are made up of paper or cloth layers and thermoset resin. Similar to substrates, laminates are created to be customizable. Laminates preferable consist of properties like high tensile and shear strength, thermal expansion coefficient, Tg and CTE. Commonly used dielectrics are polytetrafluoroethylene FR-1, FR-4, CEM-1 and CEM-3 and common pre-preg materials FR-2 through FR-6, CEM-1 through CEM-5 and G-10. Used in conjunction, the substrate and laminate define basic electrical, thermal and mechanical circuit board properties that can be used for a specific board type, and help you make the best selection for your PCB material.Now that you know what kind of materials laminates and substrates require, you will understand why flex PCB is so useful. It provides for a higher circuit density, a higher temperature operating range, size and weight reduction, and improved impedance control and reliability! Flexible printed circuits are practically everything you could want to be able to meet your PCB requirements. It also ensures that there is less errors made during assembly, and drastically reduces time and costs for assembly.Consider using flex PCB for your new project, and uncover the benefits of efficiency and effectiveness!

Flexible Printed Circuit Boards- the All-Rounder Pcb
Flexible Printed Circuit Boards- the All-Rounder Pcb
Printed circuit boards or PCBs are mainly of two types depending on their substrates, either rigid or flexible. The older pcbs were mostly rigid. In this advanced 21st era of wireless communication like mobile technology where everyone is slowly moving towards miniaturization, there was a need felt for circuit boards that were light, thin, small, flexible and had high wiring density. The pcb flexible was invented to fulfill these requirements. These printed boards are three dimensionally wired and they can also be reshaped to fit the available space.A flexible printed circuit board consists of a flexible board, wirings present on the flexible board, and connection pads which conduct through the wiring which are present on the edge of the flexible board. A copper foil is then laminated onto a resin substrate through multiple layers and then joined with an adhesive or this can be done by application of heat and pressure by a flex heater onto an integral board. To make circuits on both the sides, there can be multiple conductive layers used. The layers are namely, insulating layers, adhesive layers, and encapsulating layers which are present between the conductive layers to make sure sufficient insulation is present. Polyimide or a similar thermoplastic material like polyetherimide is the main constituent of the plastic substrate of flexible pcbs. A pcb flex cable with multiple embedded electrically conductive lines forms the substrate which is then coated with an adhesive. To ensure electrical connection to other electronic components apertures are formed in one of the insulation layers. Then these electronic devices are connected to each other. So to sum up, the front and back surfaces are covered with insulating layers which prevents one wiring pattern from being conducted to other wiring patterns which are formed on a different circuit board.Flexible printed circuit boards are easy to make. Following are the steps:1. Choose thin double side copper plated polyimide sheets and cut them to the required size. Make sure that the copper is not smudged and the edges of the sheets are even2. Next pick a solid ink printer that will print in melted wax easily. The wax will form a layer on the copper that will protect it later during the etching process. 3. To draw the diagram of your circuit, use a computer aided design.4. Print your final design on the polyimide sheet which will appear as copper traces. It is always recommended to use dark distinguishable colors. 5. Soak the printed sheet in ferric chloride. This is called etching and takes about half an hour to get done.6. Your circuit is ready to be mounted. It can be cut into smaller parts if needed. Electric components can be mounted through holes that can be drilled using laser.Conclusion:Flex pcbs are very easy to make and use. But at the same time only with the top quality material and technical expertise you will be able to make a good quality pcb which will last for a long time.

Discovery of a Female Cat with Testicles Among Weirdest Pet Claims
Discovery of a Female Cat with Testicles Among Weirdest Pet Claims
A North Shore pet owner got the shock of her life to learn her female cat also had testicles. Along with the discovery of a hermaphrodite cat, other owners have been left perplexed after discovering their pets had consumed anything from a roll of dental floss, compact mirror, blanket, sewing needle to a chicken skewer. These discoveries were among the weirdest PetCare claims received by Southern Cross last year. Lisa Newlands adopted her domestic long haired cat Cameo in 2014 with the reassurance she had been spayed. But at the end of last year, Newlands became suspicious about whether it the standard neutering had worked when her usually feisty cat started befriending a stray male. After Cameo became really sick with a high temperature and stopped eating for the second time in two months, an ultrasound revealed she had a large mass in her stomach area. The ginger cat underwent surgery and for the first time in her vet's 13 year career, she discovered two cancerous testicles in the female feline. Cancerous testicles emit oestrogen, which was why the tom cat was hanging around. "The vet was just bamboozled. She had never seen anything like this in her entire career," Newlands said. Cameo's total vet bill was $2531, but Newlands said fortunately $2013 was covered by pet insurance. Newlands estimated Cameo had racked up almost $10,000 in vet bills since she had owned her because she was notorious for getting in fights with other cats and was grateful most of it had been covered by her pet insurance. Another pet owner also claimed on a hefty $8000 vet bill after their german shepherd cut its leg on a metal shoe rack as it tried to escape from two cats. The traumatic incident resulted in the dog having to undergo two surgeries and receive post operative care. In another case, a labrador retriever went under the knife to remove pieces of a blanket it had eaten from its stomach at a cost of $6000. Another owner commented that they were amazed that the chicken skewer eaten by their miniature poodle came out whole after being endoscopically removed. And a hungry beagle's desire to snaffle up a tasty fruit cake also backfired on it after the raisins caused it to have renal failure. The wee beagle had it's kidneys flushed at the vet. But the list of weird claims gets crazier after a french bulldog ate a whole roll dental floss it had found in a visitor's bag and a Shetland sheepdog had to be treated for munching on dish cloths on two separate occasions. The mischievous mutt managed to escape surgery and was given drugs to help it either poo or vomit the rags out. And it wasn't just playful pooches causing their owners angst, a domestic long haired cat also required surgery to remove a sewing needle it had swallowed and devon rex cat had 46 hair ties surgically removed from its stomach. Both treatments cost their owners more than $2000 each. Southern Cross Pet Insurance general manager Anthony McPhail said everyday, unexpected accidents could end up costing pet owners a lot of money at the veterinary clinic. McPhail said while most of the claims processed were for typical illnesses and routine checks, the ones where pets had managed to eat something they shouldn't have still surprised them. He said the stories could be amusing, but still caused quite a lot of stress to the pet and both its owner and their wallet. "We recommend owners prepare for those unexpected veterinary visits by either setting some money aside or considering pet insurance," McPhail said.

Citing Privacy Concerns, U.S. Panel Urges End to Secret DNA Testing
Citing Privacy Concerns, U.S. Panel Urges End to Secret DNA Testing
NEW YORK (Reuters) - They're called discreet DNA samples, and the Elk Grove, California, genetic-testing company easyDNA says it can handle many kinds, from toothpicks to tampons. Blood stains from bandages and tampons? Ship them in a paper envelope for paternity, ancestry or health testing. EasyDNA also welcomes cigarette butts (two to four), dental floss ("do not touch the floss with your fingers"), razor clippings, gum, toothpicks, licked stamps and used tissues if the more standard cheek swab or tube of saliva isn't obtainable. If the availability of such services seems like an invitation to mischief or worse - imagine a discarded tissue from a prospective employee being tested to determine whether she's at risk for an expensive disease, for instance - the Presidential Commission for the Study of Bioethical Issues agrees. On Thursday it released a report on privacy concerns triggered by the advent of whole genome sequencing, determining someone's complete DNA make-up. Although sequencing "holds enormous promise for human health and medicine," commission chairwoman Amy Gutmann told reporters on Wednesday, there is a "potential for misuse of this very personal data." "In many states someone can pick up your discarded coffee cup and send it for (DNA) testing," said Gutmann, who is the president of the University of Pennsylvania. "It's not a fantasy to think about how, without baseline privacy protection, people could use this in a way that would be really detrimental," such as by denying someone with a gene that raises their risk of Alzheimer's disease long-term care insurance, or to jack up life insurance premiums for someone with an elevated genetic risk of a deadly cancer that strikes people in middle age. "Those who are willing to share some of the most intimate information about themselves for the sake of medical progress should be assured appropriate confidentiality, for example, about any discovered genetic variations that link to increased likelihood of certain diseases, such as Alzheimer's, diabetes, heart disease and schizophrenia," Gutmann said. The commission took on the issue because whole genome sequencing is poised to become part of mainstream medical care, especially by personalizing medical treatments based on a patient's DNA. That has been driven in large part by dramatic cost reductions, from $2.5 billion per genome in the Human Genome Project of the 1990s and early 2000s to $1,000 soon. Several companies, including Illumina Inc. and Life Technology's Ion Torrent division, sell machines that can sequence a genome for a few hundred dollars, but that does not include the analysis to figure out what the string of 3 billion DNA "letters" means. A three-year-old federal law prohibits discrimination in employment or health insurance based on someone's genetic information but does not address other potential misuses of the data. Without such privacy protection, said Gutmann, people may be reluctant to participate in genetic studies that do whole genome sequencing, for fear their genetic data will not be secure and could be used against them. Recommendations from such panels are not binding but have been used as the basis for policy and legislation. One scenario the panel offers is a "contentious spouse" secretly having a DNA sample sequenced and using it in a custody battle "as evidence of unfitness to parent," perhaps because the DNA showed a genetic risk for mental illness or alcoholism. There are no federal laws against that. Or, the panel said, DNA information might be posted in a social networking site "by a malicious stranger or acquaintance," possibly hurting someone's "chance of finding a spouse, achieving standing in a community, or pursuing a desired career path." The bioethics panel recommends a dozen forms of privacy protection, including that "surreptitious commercial testing" be banned: No gene sequencing or other genetic testing should be permitted without consent from the person the DNA came from, it said. About 25 states currently allow such DNA testing. Critics of the lack of genetic privacy thought greater urgency was needed. "The report lays out a lot of important best practices and does endorse further state and federal regulations, but it doesn't offer a timeline," said Jeremy Gruber, president of the Council for Responsible Genetics, a private group that monitors genetic issues. "What will inevitably happen is whole genome sequencing will enter greater use and we won't have proper regulations to insure privacy." A bill introduced in California, home to many DNA testing companies, by state Senator Alex Padilla would ban surreptitious testing, requiring written authorization from the person the genetic sample was taken from. It is not clear how many labs are willing to analyze DNA without that authorization. In practice, well-known genetic testing companies such as privately held 23andMe test only saliva samples that are too large to acquire surreptitiously, such as from a drinking glass or licked stamp. "A person would really know that they are spitting into a tube," said 23andMe spokeswoman Jane Rubinstein. The full report from the presidential commission is at www.bioethics.gov.

How to Cut Corn Off the Cob Easily, Quickly, & Safely
How to Cut Corn Off the Cob Easily, Quickly, & Safely
We've all been there: we're enjoying a nice cob of corn, happily covering our face in butter and salt, when suddenly we realize that there's a thread of corn silk stuck in our teeth. We try to dislodge it with our tongue; no luck. We pick around with our fingers; still no luck. That silk is staying there until you return home to your toothbrush and dental floss. And if you think that corn silk is bad for most people, try having braces!Cutting the kernels off corn on the cob not only helps this problem, but also makes corn a lot easier to cook with.There is a problem, of course. I'd like to think I have above-average knife skills, and yet I'm completely scared to try and cut kernels off corn on the cob. There's no way to balance the oblong cob, and you have to cut straight down. To add insult to injury, the kernels corn go flying everywhere; it's nearly impossible to cut them in a neat and orderly manner. But worry not: there are some surprisingly easy (and safe!) ways to quickly and neatly cut corn off the cob.Use a Bundt or Angel Food Cake PanI only recently found out about this (big thanks to Saveur's amazing video channel), but it's now one of my favorite food hacks. Place one end of the cob in the middle of the pan, which will keep the corn stable while you cut down. Then, as you cut the ears off of the cob, they'll collect in the pan instead of scattering everywhere.Construct a Makeshift Bundt Cake PanIf you don't have a bundt or angel food cake pan, you can make your own version. Start with a cake pan, pie dish, or shallow bowl. Then add any stable item that can hold one end of the corn, such as a narrow cup or a shot glass. (My personal favorite is a toilet paper cardboard tube, but please be careful if you try this: these tubes are remarkably flimsy, so if you apply too much pressure they will collapse while you're cutting.) Then proceed just as you would with a bundt or angel food cake pan, until you have a bowl of perfectly cut corn.Cut the Corn in HalfThis is the quickest way to get the kernels off of the cob, but you want to avoid it unless you have a nice knife and are comfortable using it. Start by cutting the corn in half, which is harder than it looks: the core of the cob is extremely hard, and the corn will want to roll while you're trying to cut. So above all, be careful!Now that the corn is in half, each piece has a flat side, making it easier and safer to balance the cob while you cut it. And with each piece half the size of a full cob of corn, there's less mess when you cut the ears off.Then again, if you're hell-bent on keeping the corn on the cob, but still want to get rid of the strings of silk, you can always microwave it.Get More Food-Cutting HacksSometimes unflavored dental floss is better at cutting certain foods than your knife-seriously! And if cutting tomatoes befuddles you, be sure to read our indispensable guide on how to do it right. As for mangoes, turns out you need to bring a drinking glass in order to cut them the right way.

Mark that spot with a red marker. Mark a spot 2 inches from the other end of the dental floss. Wrap a small piece of masking tape around that end.Thread the end of your dental floss through the tiny opening at the top of your self-threading needle, above the eye. Pull the floss through the eye of your needle until you reach the spot marked with masking tape.Thread one seed at a time onto the floss by pushing the needle through the hole you've drilled in the seed. Pull the first seed to the spot marked with the masking tape. Keep adding seeds until you've filled the length of floss between the red mark and masking tape.Remove the masking tape from the end of the floss, and knot the ends of floss together securely. Clip the loose ends of floss close to the knot with scissors to finish your necklace.Drill holes in the center of each seed or at a point that will allow the seed to be threaded so it will lie at the angle of your choosing. Thread all of one kind of seed onto your floss, or alternate seeds of different shapes and sizes. Store pieces of finished jewelry in tightly covered glass jars.Use caution when using a drill. Place seed jewelry in a deep freeze for a couple of weeks, at least once a year, to kill any insects that may infest the seeds. Never eat seeds that you use to make jewelry.
