Using the Dam & Fill Method to Protect Special Electronic Components
share
Today, new technology products require smaller electronic components, but with much greater efficiency than in the past. This has reduced the life of electronic components as well as circuit boards. Some circuit boards used outdoors, subject to a lot of vibration, such as Cars, LED lights, Cameras need special methods to protect electronic components. The Dam and Fill process is one of the new methods of protecting important electronic components, saving production space and time.
Dam and fill is a selective process that enables potting of individual areas on the PCB without affecting the surrounding surfaces and components. This process, also known as “frame and fill”, uses two potting compounds of varying viscosity. A dam or frame made of high viscosity material is first dispensed around the section of the board to be protected. The resulting cavity is then filled with a liquid casting resin until the particular structures are completely covered. This process has a lot of benefits, such as:
– Anti-moisture, Anti-damage, Anti-dirt for electronic components
– Absolutely protect important electronic components, increase product reliability
– Thermal Conductive
– Reduce material costs
– Reduce production time
