Why SMT Solder Joints Have Pinholes & Bubbles? Solder Paste & Printing Fixes

Pinholes and bubbles on SMT solder joints are common welding defects in PCB production, which directly reduce solder joint reliability, cause hidden issues like cold solder and poor conductivity, and even lead to product failure. The root causes mostly lie in two core links: solder paste selection/control and stencil printing process, rather than a single […]

How to Maintain Solder Paste Printer Properly? Key Precautions for SMT Processing Application

In SMT processing, the solder paste printer is an indispensable piece of equipment, and the quality of solder paste printing directly determines the quality of SMT surface mount processing. In actual surface mount processing, production quality is susceptible to interference from various factors, such as solder paste quality, processing parameters, temperature and humidity, and equipment […]
