With the advent of the 5G era, various electronic product components are becoming more and more miniaturized, and the gap between component pads is also shrinking. How to ensure high-quality reflow soldering, SMT solder paste printing process is one of the key links, everyone Know that there are three important parts in SMT solder paste printing: solder paste, stencil and printing equipment, if you can choose the right one, you can get good printing results.

How to control and control the SMT steel mesh in the process technology, share the latest technology of the offline cleaning method of SMT printing steel mesh provided by Unibright, and ensure that all the apertures are “0” tin beads and “0” after the steel mesh cleaning. Tin powder residue, cleaning effect

In the electronic process, the conventional cleaning method of SMT steel mesh generally adopts pneumatic spray cleaning machine. This mode is safe to operate, but the supporting cleaning agent is an organic solvent product, which has low flash point, flammable and explosive, and has certain safety hazards. After the SMT solder paste steel mesh is cleaned, the pores have tin powder residue, and the actual cleaning effect will also have certain quality risks to the SMT process products.
