What Does PCB Price Consist of?

Throughout the years, the adjustments in PCB rates have been well known to individuals inside and outside the SMT processing industry, although some individuals that have actually been participated in the PCB sector for many years may not totally recognize the ins and outs of it, so let’s analyze the main aspects impacting PCB rates:

1. The cost distinction caused by various PCB products is based upon regular double-sided boards. The boards generally have fr-4, cem-3, etc. The board thickness varies from 0.2 mm to 5.0 mm, and the copper thickness varies from 0.5 to 3oz. All of these have actually caused significant distinctions in board rates; in solder mask inks, there are also specific cost differences in between normal thermosetting oils and photosensitive green oils, so the variety of materials has triggered price distinctions.

2. The manufacturing procedures made use of in PCBs are various, and the various production procedures and costs will certainly result in different costs. For instance, the production of gold-plated boards and tin-sprayed boards, the production of the shapes of milling (milling) boards and beer (red) boards, and the use of silk screen lines and completely dry film lines will have different costs, causing a range of prices.

3. The rate difference is caused by the trouble of the PCBs. Even if the materials and processes coincide, the intricacy of the PCB itself will certainly cause various expenses. Even if the materials and processes are the same, the complexity of the PCB itself will certainly cause various costs. For example, if 2 boards have 1000 openings, one board has a hole size above 0.6 mm, and the other boards have a hole size less than 0.6 mm, various boring expenses will certainly be developed; if the two boards are the same, the line size is various. The distinction is that is greater than 0.2 mm and the various other is less than 0.2 mm, which also creates various manufacturing expenses. Due to the fact that the scrap price of hard boards is high, it will undoubtedly enhance prices, causing cost distinctions.

4. Various client needs in SMT manufacturing will likewise create various costs. The level of consumer need will straight affect the board result rate. For instance, an IPC-a-600e board needs a 98% pass rate for class 1, however according to class 3 demands, it might just be a 90% pass price, resulting in different manufacturing facility prices, and it ultimately transforms item prices.

5. Different PCB manufacturers cause cost diversity. Even if it coincides product, various expenses will be developed because of various technical devices and process levels of the producers. Currently several SMT makers like to generate tin-spraying boards since the procedure is basic and the expense is reduced, however some suppliers also produce gold-plated boards, causing a high scrap rate and high price. As a result, they favor to produce tin-sprayed boards, so the rate of their tin-sprayed boards is lower than that of gold-plated boards.

6. Price differences triggered by various repayment approaches. Presently, PCB handling manufacturing facilities typically change PCB prices according to various repayment methods, ranging from 5% to 10%, which additionally creates cost distinctions.

7. Regional distinctions cause value diversification. Today, from a local perspective, costs have a tendency to raise from southern to north. There are particular differences in costs in various areas, so different regions likewise trigger rate distinctions.
