LEAPPCB teaches you the exclusive knowledge of PCB circuitry

There are specializing in, no matter which line which industry has its own set of professional knowledge, PCB circuit board is not exceptional also, today we will please come to master professional and technical terminology to talk about some PCB, the technical personnel engaged in PCB will need:

The materials that make circuit boards usually have XPC, FR1, FR2, CEM1, CEM3 and FR4.XPC, paper core, no 94-VO fire marks;

FR1, paper core phenolic resin coated copper foil (not electroplating, spraying tin, high temperature 105 degrees Celsius);

FR2, paper core phenolic resin coated copper foil (cannot electroplating) spray tin, temperature resistant 130 degrees Celsius);

CEM1, paper core epoxy resin coated glass cloth board (broken glass fiber);

CEM3, paper core epoxy coated glass fiberboard (whole glass fiber) is generally used to produce single panel;

FR4, epoxy resin coated glass sheet (whole glass fiber) is generally used to produce double panels and multilayer plates;

Electroplating: spray tin is the hot air leveling;

Line: silk printing is to press the character, usually white;

Green oil is the green resistance flux;

Appearance: cut also call V cut, milling also call gong board;

Master the technical knowledge of the circuit board, and lay the foundation for our future work.
