Overview of circuit board proofing

Overview of circuit board proofing
Circuit board proofing, detachable understanding. PCB, that is, epoxy resin circuit board, proofing, that is, production of product samples. Therefore, PCB proofing, that is, before mass production of PCB circuit boards, commissioned manufacturers to make samples in order to confirm the feasibility of circuit design and product production plan, usually produces a small quantity.
Charge for circuit board proofing
Is there a charge for circuit board proofing? There is no absolute answer, and the market strategy, sample difficulty, sample delivery date, cooperation time and other reasons of the circuit board manufacturer will affect its results. However, judging from the current development trend of PCB boards, the manufacturers who charge for PCB proofing have accounted for the vast majority, for the following reasons:
First, the cost problem. Cost is an important index that any enterprise must evaluate. In the rigid circuit board industry, no matter how many printed circuit boards are produced, manufacturers must invest certain costs, such as labor, materials, technology, water and electricity, etc. For producing 1pcs and 1pcs PCB, the investment in technical fees and production processes are equal, and the large number of samples will bring certain cost pressure to manufacturers.
Secondly, market factors. In the PCB industry, “good and evil people are mixed”, and there are real demanders, but there are countless middlemen (especially individuals) who do trade. In order to reduce the cost to the maximum extent, this kind of traders often cheat manufacturers to make PCB samples, take samples and sell them to other traders or demanders, and then they won’t place any more batches, which leads to large losses of enterprises;
Third, the charge for proofing can attract the attention of manufacturers, thus ensuring the delivery and quality to a certain extent.
PCB proofing manufacturer distribution
PCB belongs to the electronics industry, and the electronics industry gathers in the Pearl River Delta region of Guangdong, especially Shenzhen has become a world-class electronics market. Therefore, PCB manufacturers are mainly distributed in Shenzhen, Dongguan, Zhongshan, Zhuhai and other coastal areas.
