Specialize in, no matter what industry has its own set of professional knowledge, PCB circuit board is no exception, today we have invited to professional and technical teacher to tell a story about some PCB board professional term, will be used in the circuit board and technical personnel as below:
Material for the production of circuit boards are usually XPC, FR1, FR2, cem1, cem3 and fr4.xpc, paper core, no 94-vo fire mark;
FR1 PCB, the paper core phenolic resin copper-clad plate (not plating, tin spraying, high temperature 105 degrees Celsius);
FR2, the paper core phenolic resin copper-clad plate (not] electroplating tin spraying, high temperature 130 degrees Celsius);
Cem1, the paper core epoxy resin copper clad glass plate (glass fiber);
Cem3, paper core epoxy resin coated glass fiber board (the whole glass fiber) is generally used for the production of a single panel;
FR4 PCB, epoxy resin copper clad glass cloth (whole glass fiber) is generally used for production of double-sided and multilayer board;
Plating: tin spraying is hot air leveling;
Line: silk screen is printed on the customer requirements, the general is white;
Master above the professional and technical knowledge of the circuit board, to lay the foundation for our future.
