The PCB manufacturing process of the circuit board prototyping manufacturer is a complex series of steps, starting from the initial opening and culminating in the final packaging and storage. This process involves cutting the sheet material and progressing to PCB board production. The specific steps include opening and inner layer production, lamination, drilling, copper immersion, electroplating, outer layer production, inspection, solder mask application, text printing, surface treatment, final inspection, and final packaging and storage.
Following automatic optical inspection, circuit board prototyping manufacturers utilize a lamination process to create separate layers. Next, small diameter tungsten carbide drill bits are used to drill holes in the PCB, designed to prevent tear marks. Alternatively, a laser can be employed for drilling to create very small through holes. These holes can be made conductive through plating or perforations, with the depth controlled to only allow conduction to specific layers.
The PCB is then electroplated with solder to provide a resistant surface for etching. Areas that will not be soldered are covered with solder mask, applied through screen printing or photo imaging. Before components are added, the PCB is tested to ensure proper connections. Once verified, the components are assembled to create a functional printed circuit assembly.
The final stage for the circuit board prototyping manufacturer is the application of a protective coating to prevent corrosion and leaks. The manufacturing process is evolving as manufacturers strive to minimize potential risks to their production workers, such as reducing the use of chemicals like lead. While lead has traditionally been used in PCB production, awareness of its health impacts has prompted changes in manufacturing practices. A recent publication on printed circuit design and fabrication highlighted health concerns and emphasized that the shift towards safer chemical processes is being driven by NGOs.
