Nozzle maintenance precautions:

Steps for manual cleaning: These are the two different methods of PCBA cleaning, and choosing the appropriate cleaning method based on the current situation is crucial. We hope this information is helpful to you.

During the PCBA manufacturing process, residues of solder paste and flux are inevitable. Over time, these residues can solidify, forming corrosion substances such as metal halides, which can adversely affect the stability and lifespan of the PCB. Therefore, it’s essential to thoroughly remove residual solder paste, flux, and other contaminants from the surface of PCBA…

The solder paste process plays a crucial role throughout the entire PCBA manufacturing process, ensuring reliable electrical connections between surface mount components and PCB pads while providing adequate mechanical strength. Let’s explore the solder paste process, technical requirements, and cleaning solutions.

PCBA circuit boards are widely used globally, and during the manufacturing of printed circuit boards, contaminants such as solder flux and adhesive residues, as well as dust and debris generated during production, can accumulate. If the PCB surface cannot be effectively cleaned, issues such as resistance and leakage can occur, leading to abnormalities in the…
