Detailed Information on Flexible PCBs Explained by a Flex PCB Assembly Company
If you are in the business of manufacturing electronic gadgets for industrial purposes, then you are aware of PCBs. Printed circuit boards are the lifeline of almost every electronic digital device. In most cases, manufacturers create a machine which can accommodate the PCB in it. However, there is another option which these manufacturers need to consider. Instead of a regular PCB, you should think about using a flex PCB. With a flexible printed circuit board, you dont have to design a device which can fit the circuitry. Regardless of the shape and dimensions of the gadget, flex PCBs can find their place inside them.1. Single-sided flex: If you are new to the world of flexible printed circuit boards, then you need to learn more about them. Unless you have a thorough understanding of this component, you cant make the right purchase. Companies which take care of flex PCB assembly create several types of this constituent. Single-sided flex circuits are the most basic varietal, and they contain a single layer of metal trace. It lies on one side of the dielectric layer. This dielectric part can be of polymer or polyimide. The purpose of the polyimide overlay is for insulation and protection from degrading the environment.2. Double-sided flex: As the name suggests, it is the enhanced version of the single-sided flex. Of course, you have to choose a flex PCB assembly based on the purpose of use. A double-sided flexible printed circuit board has several layers on either side. In spite of that fact, manufacturers use only one dielectric layer. They plate the two layers by metalizing through holes to create connections.3. Multi-layer flex: The third component on the list is a multi-layer flexible printed circuit. These segments have several layers of copper. Dielectric layers remain sandwiched between the copper coatings. As with double-sided flex PCBs, holes connect the metal layers. As you can understand, the interconnections of a multi-layer flex circuit contain more complex interconnections and layer surface design mounting. 4. Rigid-flex: A rigid-flex PCB consists of multiple layers of circuitry. Manufacturers use an epoxy pre-preg bonding film to establish connections between the circuit layers. The result resembles a multi-layer flex circuit. All flex circuits are a combination of flex circuitry and rigid board circuitry. However, rigid flex circuits possess a much higher component density.Now you are aware of the different types of flex circuits. So, it is time to learn about the materials used by manufacturers.1. Electricity conductors: It is easy to understand the fact why manufacturers use conductors. If the PCB doesnt allow electricity to pass through it, then it becomes worthless. Copper is the most commonly used conductor.2. Glues: Manufacturers rely on adhesives for surface-mount component binding. Customers have to specify the adhesive requirements based on requirements and thickness of conductors. Some of the glues used include acrylic, epoxy, etc. There are a few flex PCBs where manufacturers dont apply adhesive at all.3. Insulating substances: The purpose of an insulator on a flex PCB is to separate the electrical conductors. They also serve to support the component. A few typical insulators used in flex PCBs are polyester, polyimide, polyethylene naphthalene, solder mask, and polyethylene terephthalate.Use according to necessitiesYes, now that you are aware of these constituents, you can think about utilizing them for your products. However, you should choose them based on what you produce. If you are satisfying the demands of your customers by using conventional PCBs, then you should stick to that. You can consider using flex circuits for any new product that you will launch in the future. RELATED QUESTION Can Thailand become a MedTech Innovator instead of a MedTech customer? Thailand is well poised for building and sustaining a start-up culture, encouraged by the governmentu2019s Thailand 4.0 vision, which has seen entire sectors of the economy being rebuilt with new technology and overseas investment. A dedicated programme called u2018Startup Thailandu2019, set up by the National Innovation Agency (NIA), hopes to accomplish this by reforming government procurement, building innovation districts, and increasing international cooperation. As well as building the infrastructure of railways, airports and smart cities to support the new industries, the government is also investing heavily in its university system to boost research activity and train the thousands of engineers and scientists that will be needed for the planned expansions in targeted industries such as the biotech, biochemical, medtech and roboticsThe Thai government has progressive policies in place to help the country attain the position of u201cThailand, a Hub of Wellness and Medical Servicesu201d within a ten-year timeframe (2016-2025). The plan focuses on four major areas: wellness, medical services, academic and medical centres, and health products. The government also provides additional technology-based incentives for investment in the development of core technologies u2014 biotechnology, nanotechnology, advanced material technology, and digital technology u2014 and enabling services that support targeted technology development. But will all this be enough?To find out, we spoke with Dr. Kakanand Srungboonmee, from the Centre of Data Mining and Biomedical Informatics, Faculty of Medical Technology, Mahidol University, in Bangkok Thailand.As well as being an academic, innovator and start-up founder herself, Dr. Srungboonmee is also key in curating the speakers and topics for the Start-up Podium which will take place at MEDICAL FAIR THAILAND 2019 from 11 to 13 September in Bangkok.1. How would you describe the life sciences and medical/ health startup scene in Thailand?The life sciences and medical/health start-up ecosystem in Thailand is in an early stage. We are comparatively new to the idea of innovating our own solutions to our own problems. We have been good customers for a long time, using products invented and manufactured elsewhere in the world. Thailandu2019s medical device market is the eighth largest in the Asia-Pacific region. Estimated in 2015 to be worth more than US$1. 2 billion, it is expected to grow at a high single-digit rate (CAGR of 8.1 per cent during 2015 to 2020) to reach US$1.7 billion by 2020. Consumable devices and diagnostic imaging are among the products with large market share, followed by orthopaedics and prosthetics, dental products and patient aids. Local production is limited to consumables and basic medical devices.There are around 320 local manufacturers, mostly Small and Medium Enterprises (SMEs) producing products such as diagnostic kits, syringes, surgical gloves and catheters. Over 80 per cent of domestic production is for export. Thailand continues to rely on import to supply most of the market, particularly highgrade and sophisticated medical devices. When those foreign products have not really met our needs, we have used our natural patient and adaptive tendencies to make them work for us or we have worked around their shortfalls. Now that is beginning to change and we are seeing more Thai start-ups innovating solutions for the local market. As Thailandu2019s medical device market continues to grow there will be great potential for local companies and innovators to develop products to meet demand in many areas including those related to surgical procedure equipment, implanted medical devices, respiratory devices and oxygen therapy, orthopaedic implant devices, heart valves, neurosurgical devices, rehabilitation equipment and accessories, and dermatological devices.One of the challenges we face at this stage is that the innovators/developers are often working at a distance from the healthcare environment without direct input from healthcare professionals. That can lead to the true needs of patients or healthcare professionals not really being met. We need more collaboration between healthcare professionals and the innovators, and the IT and engineering professionals trying to develop solutions. At the beginning of the process we need the healthcare professionals to identify an unmet need and then we need them to be giving feedback to the development team throughout the process.Another challenge is that coaches and mentors for medical industry startups are difficult to find as the industry is still young in Thailand. Again, collaboration could be the answer. If entrepreneurs with start-up experience in other tech sectors, healthcare professionals, young MedTech innovators, established industry players, and the government sector can work together, we can build the necessary ecosystem to support MedTech startups.2. Why is it important to innovate for the life sciences and medical/ health industry?Innovation is important for the life sciences and medical/health industry because the current healthcare model is unsustainable. The traditional healthcare system has focused on treating people in hospital and then sending them home and the innovation has focused on looking for new treatments. But waiting for people to become acutely ill and then treating them is very expensive, and as our population grows older, that approach will become more and more unsustainable. Thailand is currently moving from an ageing society towards an aged society. By 2032, the proportion of ageing population is expected to reach 32.2 per cent of the population (from 16.5 per cent in 2016). Along with the reduced fertility rate, this will not only impact the countryu2019s healthcare system but also its economic productivity. To cope with the impact of our ageing society, innovation in the life sciences and medical/health needs to focus more on promoting wellness and a healthier lifestyle. It needs to be looking for preventative treatments, earlier detection of disease and earlier interventions to treat or manage the disease before it becomes serious and requires hospitalisation.3. What are the main challenges in innovating for the life sciences and medical/ health industry in Thailand?We do not really have a co-working space specifically designed for life sciences and medical/health innovation. Developers and clinicians are not just figuratively working in their own silos and not talking and sharing ideas, they are actually physically separated from the clinicians and healthcare professionals. The innovators are working in offices over here, the engineers are in an industrial park over there and the clinicians and healthcare professionals are in a hospital somewhere else; they are not all part of the same ecosystem. So their true requirements are not really being met because they are not talking to, and working with, the innovators and developers.4.How can these challenges be overcome?We need to have co-working spaces that are especially designed for healthcare innovation. The co-working space should facilitate the development of the sort of ecosystem needed for medical industry innovation, with good coaching and mentoring systems from the clinical and industry sides. There should be start-up incubation spaces and engineering facilities on the campuses of the big research hospitals and collaboration and communication should be encouraged and facilitated.5. What are the main challenges in founding and sustaining a life sciences and medical/ health startups in Thailand?We do not have good coaches and mentors with experience in the medical business. Most of the start-up incubators do not really work with or have experience in medical industry. Start-ups have to find their own ways or share resources, including investor resources, with start-ups in other industries. We also need investors who understand the challenges faced by life sciences and medical/ health startups. General investors are interested in the healthcare industry but they are used to faster development times and seeing quicker returns on their investments in other industry sectors. So when they see the challenges faced by the life sciences and medical/health sectors such as the longer time needed for development and clinical trials, stricter standards and more restrictive marketing regulations, they usually give up.6. How can these challenges be overcome?We need incubators who are experienced in life sciences and medical/health industry. Longer term support is also needed in the life sciences and medical/health industry; accelerators should work not just at the level of incubating the business but also in the various stages of development.Additionally, because investing in the healthcare industry costs more and takes longer to see returns compared to other industries, healthcare startups need opportunities to meet with investors who are familiar with the life sciences and medical/health industry and understand the challenges and time frames involved.7. What can be done to make innovation a stronger priority for the life sciences and medical/health industry in Thailand?The government, industry players, innovators all need to realise that life sciences and medical/ health innovation promotes sustainable wellness and wellbeing. It is this technology that directly helps us live healthier and better lives. An ecosystem suitable for life sciences and medical/health innovation should be created to help accelerate the innovations that will keep Thais living longer, healthier, happier, and economically more sustainable lives.Can Thailand become a MedTech Innovator instead of a MedTech customer?.
