/Pcb manufacturing surface coating technics principle
Pcb manufacturing surface coating technics is the first important link of electronic product manufacturing technics. 60%~70% of defects come from coating technics in electronic product manufacturing technics . Therefore, the quality of Pcb manufacturing surface coating technics is one of the key factors which affect board qualified ratio.
Pcb manufacturing and printing coating technics include two main technics: coating soldering technics and coating SMT technics. The so-called pcb coating soldering technics uses the coating equipment and the stainless steel stencil to accurately apply the solder paste to the specified position on the PCB before the components are mounted on the PCB. Pcb manufacturing coating SMT technics by applying adhesive glue to a specified location on a PCB using SMT processing dispensing device or SMT processing printing device.
The Pcb surface coating technics is a technics technique used by pcb manufacturers to assemble pcb components and is also an important point coating manufacturing technics technique.
The above is the professional information provided by the pcb manufacturer.

① Standard components should pay attention to the dimensional tolerances of components from different manufacturers. Non-standard components must be designed in accordance with the actual size of the components and the land pattern and the space between the land. ② When designing high-reliability...
The water cleaning process of PCB circuit board uses water as the cleaning medium. A small amount (usually 2% to 10%) of surfactants, corrosion inhibitors and other chemicals can be added to the water. The PCBA cleaning process is completed by washing, washing and drying the source of pure water ...
