Complex process of production PCBs

Complex process of production PCBs

The PCB manufacturing process usually begins with the process engineer designing the circuit board and the negative film according to each individual’s needs and engineering drawings. The negative film production usually needs to be carried out in the space of the constant temperature and constant humidity clean room. Usually, it is made into hard printing. Negative films are required for use in the exposure process. Film subjects are exposed on the film in accordance with CAD or CAM data. Therefore, PCB practitioners must have professional knowledge and professional skills.

In the PCB production line, it is divided into two major departments: production and quality control. Usually, the employees in the production department need to do the work items including the progress, material allocation, personnel deployment and supervision on the production line; It is a process engineer who is responsible for the definition and improvement of the product manufacturing process, the handling of abnormal conditions, and reducing the failure rate on the production line to improve product quality and increase production. If there is a problem in the production line, the process engineer must solve the problem as quickly as possible.

Complex process of production PCBs

PCB is a fine-grained wiring made by printing, photographic, etching, and electroplating technologies. It serves as a platform for supporting the assembly of electronic parts and circuits between parts. Because of the complex process of producing printed circuit boards, you have to find the experienced company for PCBA manufacturing.

The waste liquid and waste generated in the process of making PCB are numerous and complicated, and in addition to containing a variety of organic pollution, PCB contains a large amount of copper and lead. And heavy metal materials such as nickel, not only the pollution intensity is large, and the pollution characteristics tend to be complicated with the improvement of the product level. If the pollution prevention work is not done well, it will seriously cause environmental pollution and injury.
