Precision Multi-layer Circuit Board:

a, The refinement of precision multi-layer PCB circuit board wires and the miniaturization of through-holes have improved the requirements for the processing equipment and process control level of PCB circuit board processing factories. It is also a test of the overall management ability and personal ability of employees in precision multi-layer PCB circuit board factories. The production capacity of 6/6mil line width/line spacing is not too difficult within the current equipment, materials, and process control level, and most PCB manufacturers can produce it. However, increasing from 6/6mil to 5/5mil is a significant leap, which has left many small and medium-sized manufacturers amazed. It may seem simple, but in fact, it requires circuit board processing manufacturers to have strong technical research and development capabilities and financial strength. Due to the performance parameters of the exposure machine, the processing ability of the etching line, and the control ability of the entire process, it is necessary to achieve a 5/5mil circuit and maintain a high yield rate, which requires the overall strength of the factory to support. Similarly, the same applies to the production of precision multi-layer PCB circuits with finished apertures of 0.3mm and below (holes below 0.3mm cannot be drilled by machine, usually by laser drilling).

b, Other issues commonly encountered by PCB manufacturers, such as lack of copper in the holes, detachment of green oil, BGA black PAD in the sinking gold plate, and solderability, should be different from each other. However, as a special process product, PCB boards integrate various traditional technologies and means such as machinery, electrical control, automation, chemistry, biology, ERP, cost, management, and environmental protection. It requires managers to exert great wisdom and employees to carry forward great spirit in order to strive to control every detail and maximize their quality control ability and level.

c, Ensure the effectiveness of process testing. PCB, as the carrier of all electronic components, its reliability is very important. A small strand of hair or dust can lead to the scrapping of the entire PCB board or potential failure hazards. So how is the quality guaranteed? Usually, people believe that quality should be produced, but in fact, it is not. If a PCB factory can adjust and control common quality problems from the perspective of effective quality control from the beginning of design, including factory layout, determination of process flow, selection of production equipment, manpower allocation, effective evaluation of raw materials, determination of management system, etc., and fully consider improving production efficiency, So the quality control and production capacity of this factory in the future will have a good foundation and guarantee. If the design work is done well, which means controlling the source and laying the foundation, will the next work be easier to do? This is the most effective method to control PCB production process and improve quality.
