PCB materials are usually XPC, FR1, FR2, specializing in the industry, no matter which industry has its own set of professional knowledge, PCB circuit board is no exception, today we will tell you about some PCB circuit board professional terms, technical personnel engaged in the circuit board will be used:
CEM1, CEM3 and FR4. XPC, paper core, no 94-vo fire mark;
FR1, paper core phenolic resin coated copper foil (can't electroplate, spray tin, high temperature resistant 105 c);
FR2, paper core phenolic resin coated copper foil (no electroplating] tin spraying, high temperature resistance 130 c);
CEM1, paper core epoxy resin coated copper glass cloth board (broken glass fiber);
CEM3, paper core epoxy resin coated copper glass fiber board (whole glass fiber) is generally used for the production of single panel;
FR4, epoxy resin coated glass cloth board (whole glass fiber) is generally used for the production of double panel and multilayer board; PCB circuit boards
Electroplating: spray tin is hot air leveling;
Line: the silk screen is printed on the characters according to the customer's requirements, usually in white;
Green oil is the green solder;
PCB circuit boards Shape: cut is also called V cut, milling is also called gong board;
Master the above professional technical knowledge of PCB circuit boards, laid a foundation for our future work
The difference between PCB and PCBA
What is a PCB? How did PCBA evolve? What is the difference between PCB and PCBA? Let's take a closer look below.
PCB is the abbreviation of Printed Circuit Board. Because it is made by electronic printing, it is called "printing" circuit board. PCB is an impor...
