What does it take to build a circuit board? For starters you can’t build a printed circuit board without materials. What types of materials to be used are defined by the customer supplied documentation and or by the methods/release engineer. If requirements are not specified by the customer the methods/release engineer shall default to IPC standards. The various manufacturing operations used are a series of added and subtractive processes. All of which are determined by the methods/release engineer. It takes many different types of chemicals and materials to fabricate the printed circuit board. The most important material is what we start with and that’s the base copper clad laminate.
Base laminate is typically copper clad FR4. FR4 is a composite material consisting of (more…)
