PCB line board price analysis

　　PCB price consists of the following factors:

　　1. The materials used in PCB line boards are different

　　Taking ordinary double panels as an example, plate materials generally include FR-4, CEM-3, etc., the thickness of the board ranges from 0.6mm to 3.0mm, and the copper thickness is different from ½OZ to 3 OZ. In terms of welding ink, there is a certain price difference in ordinary thermal solid oil and light sensitive green oil.

　　2. PCB uses different production processes

　　Different production processes will cause different costs. For example, the gold -plated board and tin spray plate, making the gong (milling) board and beer (punch) board, the use of silk print lines and dry membrane lines will form different costs.

　　Third, the PCB line board itself is difficult to be different

　　Even if the materials are the same and the craftsmanship, the difficulty of PCB itself will cause different costs. For example, there are 1,000 holes on both line boards, and one plate aperture is greater than 0.6mm and the other plate pore diameter is less than 0.6mm to form different drilling costs. Different, a kind of one is greater than 0.2mm, and one of them is less than 0.2mm, which will also cause different production costs, because the difficulty -in -board discount rate is higher, and the inevitable cost will be increased.

　　4. Different customer requirements will also cause the price to be different

　　The high and low requirements required by the customer will directly affect the finished product rate of board factories. For example, a board is 98%of the qualified rate of 98%according to the IPC-A-600E, but the requirements of CLASS3 may only have a qualified rate of 90%.
