Q:What are the materials used for the Merrillas on PCB circuit boards?
Mylar sheet (MYLAR film) is a PET polyester film, it is by the dimethyl terephthalate and ethylene glycol in the relevant catalyst with the help of heating, after ester exchange and vacuum polycondensation, biaxial stretching film.
Q:PCB board can be stored for how long
PCB board storage for how long, and surface treatment, gold and gold plating is the longest preservation time, in constant temperature and humidity conditions, you can save two or three years. Followed by spray tin and antioxidant. Especially anti-oxidation, get the board after the best on-line, it saves the shortest time. About 3 months. Stock long time board must be baked before the line, or when the reflow is easy to burst board.
Q:PCB board in the multi-layer is what it means
A multi-substrate is made by stacking two or more circuits with each other, with reliable pre-set interconnections between them.
Q:PCB printed circuit board, the "printed" is not referring to thermal transfer? Mass production PCB is also produced by thermal transfer method?
Batch should be photographic production with film printing. The Then UV exposure. Heat transfer is convenient. But the accuracy of a search like it
Q:Multilayer circuit boards, is not all power must be placed on the inner layer
Multi-layer circuit board, not all power must be placed on the inner layer, the internal layer can also be traced.
Q:What is the light blue oil component used for brush circuit boards
The gravure plate is photographed with a good background, and the layout should be the same size as the PCB. PCB photolithography process is roughly the same as the ordinary camera, can be divided into: slice cutting - exposure - development - repair - washing - dry - revised version. Perform the camera to check the correctness of the base map,
Q:Circuit board how to see the line
Above is an example of ordinary CRT TV, but now the LCD LCD / PDP plasma TV most of the line principle and ordinary CRT TV is different, which requires you to see some of this book. Player, line principle and the above products are completely different, if you want to understand MP3, you have to see some of this book.
Q:Do PCB board board In addition to materials such as CCL, there are other materials of the board?
Generally, the reinforcing material of the board is divided into five categories: paper base, glass fiber cloth base, composite base (CEM series), laminated multilayer board base and special material base (ceramic, metal core base, etc.).
Q:How to eliminate the protection of IC on the circuit board paint
Circuit board: Printed Circuit Board (PCB), also known as circuit boards, PCB board, aluminum plate, high frequency board, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards.
Q:What is the printed circuit board circuit
Printed circuit board it has two functions: 1, fixed components; 2, according to the circuit diagram with the wire to connect the components to form a solid circuit.
