PCB board processing is the process of processing copper-clad boards with copper foil on insulating substrates into circuit boards with specific lines. For example, if you want a remote control circuit board, then order to circuit board factory, then circuit board factory can make the drawings you provide.
The circuit board for welding components is the processing of circuit boards (also called PCB processing).
PCB price is composed of the following factors:
First, the different materials used by PCB result in price diversity.Take the common double panel as an example, the sheet metal generally has FR-4, CEM-3 and so on, the thickness of the sheet varies from 0.6mm to 3.0 mm, and the thickness of copper varies from? Oz to 3 Oz, all of which cause a huge price difference in sheet metal; in the aspect of solder resistance ink, generalThermosetting oil and photosensitive green oil also have a certain price difference, so different materials lead to price diversity.
Two. The difference in production process used by PCB results in price diversity.Different production processes can cause different costs. For example, gold-plated and tin-sprayed boards, Gong (milling) boards and beer (punching) boards with different shapes, and the use of silk-printed and dry-film circuits will result in different costs, leading to price diversification.
Three, the price diversity caused by the difficulty of PCB itself.Even if the material is the same, the process is the same, but the difficulty of PCB itself will result in different costs. If there are 1000 holes in both circuit boards, the aperture of one board is greater than 0.6mm and that of the other board is less than 0.6mm, the difference will be formed.
If the other two PCBs are the same, but the line width and line spacing are different, one is larger than 0.2mm and the other is less than 0.2mm, it will also cause different production costs, because the scrap rate of difficult PCBs is higher, the inevitable cost will increase.It creates diversity of prices.
Four, different customers will also cause different prices.The level of customer requirements will directly affect the finished product rate of the board mill. For example, a board according to IPC-A-600E, class 1 requires 98% qualified rate, but according to class 3, it may only have 90% qualified rate, thus resulting in different costs of the board mill.The price of products is changeable.
Five. Price diversity caused by PCB manufacturersEven if the same product, but because of different manufacturers of process equipment, technology level, will also form a different cost. Nowadays, many manufacturers like to produce gold-plated sheets, because the process is simple, low cost, but there are also some manufacturers to produce.
Gold-plated panels, scrap is rising, resulting in higher costs, so they prefer to produce tinplate, so their price of tinplate is lower than that of gold-plated panels. Processing PCB is very simple. First, export your PCB file according to the manufacturer's requirements, and write a good phase.Pass the production requirements, and then issue to the manufacturer.
Depending on the plate you choose, the current domestic price of double-sided PCB varies from 0.1 yuan to 1 yuan per square centimeter. Multilayer boards are more expensive. And the price is also related to your requirements: whether to require pinhole inspection, whether to coat the solder barrier layer, pad.
Tin plating or gold plating.
Dongguan Huaqiang quickly has scattered PCB processing place, you can look for it.
PCB processing cycle, the fastest, now 2-3 days to get, the slowest 4-6 days.
