Most electronics factory purchasing personnel have worked forPCBConfused by the ever-changing prices, even if some have been around for many yearsPCBPeople with purchasing experience may not fully understand the whole story. In fact,PCBPrice is made up of a variety of factors:
one,PCBDifferent materials used result in price diversity
Taking ordinary double-sided panels as an example, the sheets generally haveFR-4,CEM-3Wait, the thickness of the plate changes from0.2-3.6mmvaries, the copper thickness ranges from halfOZarrive3OZDifferent, so these cause a huge price difference in sheet materials alone; in terms of solder mask ink, there is also a certain price difference between ordinary thermosetting oil and photosensitive green oil, so the difference in materials results in a variety of prices sex.
2,PCBDifferences in the production process used result in price diversity
Different production processes will result in different costs. For example, gold-plated plates and tin-sprayed plates, shape-making gong plates and punching plates, and the use of silk-screen circuits and dry film circuits will all result in different costs, resulting in price diversity.
3,PCBPrice diversity caused by different difficulty levels
Even though the materials and processes are the same,PCBDifferent difficulty levels will also result in different costs. For example, both types of circuit boards have1000holes, the hole diameter of a plate is larger than0.6mmThe hole diameter of the other board is smaller than0.6mmDifferent drilling costs will result; for example, two types of circuit boards are the same but have different line widths and spacing, and one type is larger than0.2mm, all of which are smaller than0.2mm, will also result in different production costs, because the scrap rate of difficult boards is relatively high, which will inevitably increase the cost, thus resulting in price diversity.
4,Different customer requirements will also lead to different prices.
The level of customer requirements will directly affect the yield of the board factory. For example, a board pressIPC-A-600E,class1Requirements98 percentPass rate, but according toclass3The requirements may only be90 percentThe pass rate leads to different costs for board manufacturers, and ultimately leads to variability in product prices.
5,PCBPrice diversity caused by different manufacturers
Even if it is the same product, different manufacturers will have different costs due to different process equipment and technical quality. Nowadays, many manufacturers like to produce spray tin plates because the process is simple and the cost is low. However, some manufacturers also produce spray tin plates with a scrap rate The price rises, causing the cost to increase, so they would rather produce gold-plated plates, so their price for gold-plated plates is lower than that of tin-sprayed plates.
6,Price differences caused by different payment methods
at presentPCBBoard manufacturers generally make adjustments based on different payment methods.PCBPrice, range is5 percent-10 percentNot equal, which also results in price differences.
