Over the years, the changes in PCB costs have been well known to individuals inside and outside the SMT handling industry, although some individuals who have been engaged in the PCB sector for years may not completely comprehend the ins and outs of it, so allow’s evaluate the major elements affecting PCB rates:
1. The rate difference brought on by various PCB materials is based upon regular double-sided boards. The boards normally have fr-4, cem-3, etc. The board thickness ranges from 0.2 mm to 5.0 mm, and the copper density varies from 0.5 to 3oz. Every one of these have resulted in big distinctions in board costs; in solder mask inks, there are likewise certain price differences between normal thermosetting oils and photosensitive eco-friendly oils, so the variety of products has actually created price distinctions.
2. The manufacturing procedures made use of in PCBs are different, and the various manufacturing processes and rates will lead to various prices. As an example, the production of gold-plated boards and tin-sprayed boards, the manufacturing of the forms of milling (milling) boards and beer (red) boards, and making use of silk screen lines and dry film lines will certainly have different expenses, causing a variety of prices.
3. The rate difference is brought on by the trouble of the PCBs. Even if the products and procedures coincide, the complexity of the PCB itself will certainly result in different expenses. Even if the products and processes are the same, the intricacy of the PCB itself will certainly result in various costs. As an example, if two boards have 1000 holes, one board has an opening size more than 0.6 mm, and the other boards have a hole size less than 0.6 mm, different exploration prices will certainly be created; if the two boards are the same, the line width is different. The difference is that one is higher than 0.2 mm and the other is less than 0.2 mm, which also causes various manufacturing expenses. Since the scrap rate of difficult boards is high, it will inevitably increase costs, causing rate differences.
4. Various consumer demands in SMT manufacturing will certainly additionally trigger different rates. The degree of consumer demand will directly impact the board result price. As an example, an IPC-a-600e board needs a 98% pass price for class 1, yet according to course 3 demands, it may just be a 90% pass price, resulting in different manufacturing facility expenses, and it finally changes product prices.
5. Different PCB makers create cost variety. Even if it is the same item, different expenses will certainly be created as a result of various technological devices and process degrees of the producers. Currently many SMT manufacturers like to generate tin-spraying boards due to the fact that the process is straightforward and the cost is reduced, however some makers likewise generate gold-plated boards, resulting in a high scrap rate and high price. Therefore, they like to produce tin-sprayed boards, so the rate of their tin-sprayed boards is lower than that of gold-plated boards.
6. Price differences caused by different settlement approaches. Currently, PCB handling factories generally adjust PCB costs according to different settlement approaches, ranging from 5% to 10%, which additionally triggers rate differences.
7. Regional differences bring about value diversity. Currently, from a regional viewpoint, costs often tend to raise from south to north. There are specific differences in costs in various regions, so various areas likewise create price distinctions.
