Precision of multi-layer PCB circuit board

The ultra-precision multi-layer PCB circuit board wires are refined and the through holes are miniaturized, which raises the requirements for the control level of the processing equipment and technology of the Shenzhen circuit board processing plant. At the same time, it also improves the overall management ability and The test of employee's personal ability. The line width/line spacing production capacity of 5/5mil is not too difficult within the current equipment, materials, and process control level. Most PCB proofing manufacturers can make it. However, it is a big leap to upgrade from 6/6mil to 5/5mil, which makes many small and medium-sized manufacturers amazed. It seems simple, in fact, this requires circuit board processing manufacturers to have strong technical research and development capabilities and financial strength. Restricted by the performance parameters of the exposure machine, the processing ability of the etching line, and the control ability of the entire process, to achieve a 5/5 mil line and maintain a high yield rate requires the strong overall strength of the factory to support. The same is true for the production of finished apertures of 0.3mm and below (holes below 0.3mm cannot be drilled by machine, generally laser drilling).

The importance of PCB board as a carrier of electronic components
As the carrier of all electronic components, PCB proofing is very important for its reliability. A tiny strand of hair or a tiny particle of dust may cause the entire PCB board to be scrapped, or lead to potential failures. So how is the quality guaranteed? Usually everyone thinks that quality should be manufactured, but it is not. If a PCB factory from the beginning of design, including the layout of the factory, the determination of the process flow, the selection of production equipment, the allocation of manpower, the effective evaluation of raw materials, the determination of the management system, etc., can start from the perspective of effective quality control, To make corresponding adjustments, control, and prevention for common quality problems, and fully consider improving production efficiency, then the future quality control and production capabilities of this factory will have a good foundation and guarantee.
