How to choose a good PCB proofing factory

First of all, to clarify the amount of their own use, from their own use of the demand to find the corresponding circuit board prototyping factory, the current market has a lot of types of board factories, there are to do large quantities, there are military boards, there are to do soft boards, there are to do small and medium-sized batch, proofing, and there are only do simple boards. There is no best, only the most suitable.

Secondly, to choose a formal and professional circuit board manufacturers, we must look at their production capacity. Review the strength of a circuit board manufacturers, specifically look at a few aspects

First look at whether he can independently complete the process from the opening to the surface treatment to the later electronic testing, milling slot. The most critical mainly in the optical imaging, etching, solder resist, surface treatment, drilling. And then to the process capability, the domestic small factory generally do 2 live 4 layers, high point to do 8 layers of PCB, and powerful manufacturers can do the standard 12 layers, or even 26 layers of higher circuit boards. (The number of layers refers to a PCB can be wired number of layers, PCB board by more than one single-layer board through the PP sheet connection pressed together, without a certain degree of technology can not be done, the difficulty in the interference between the PCB line, the quality of the press, the machine accuracy, etc.) and then there are manufacturers to provide the parameters of the process capability, line width and line spacing, copper thickness, thickness of the soldermask layer, and so on. The circuit board factory to carry out strict quality control of the product is also very important, the board factory to ensure that the appearance of each product is intact, full performance before entering the market, the more formal manufacturers of quality control requirements on the better, the inspection process is more professional.

Then, on the after-sales service, choose a formal and professional circuit board manufacturers is also very critical, that is, after the purchase of products in the PCB demand manufacturers or companies, may be products in the factory will not have a problem, but in the specific use, may be due to certain reasons PCB board will have problems, the product has a problem, the circuit board proofing factory will provide a series of after-sales service to Ensure the normal use of the product to ensure the interests of consumers.

Lastly, on the price, due to the formal and professional circuit board manufacturers because of their different sizes, different production capacity range, so they give the offer is also different, if it is after the selection of the comparison, the inspection of the formal and professional circuit board manufacturers, factories have their own reasonable price system, do not have to worry about chaotic offer of the problem, choose to accept the reasonable offer and circuit board manufacturers To cooperate, do not choose because of the cheap choice of informal and professional circuit board manufacturers, so that there will be a lot of follow-up questions, the above is the choice of circuit board manufacturers to consider the factors.
