Click on the title below “Yingchuangli” to quickly follow Air bubbles generated during PCBA soldering, commonly referred to as voids, typically occur during the reflow soldering and wave soldering processes in PCBA manufacturing. So, how can we prevent air bubbles during PCBA soldering? 1. Baking Bake PCBs and components that have been exposed to air … Read more
Introduction Soldering is a crucial process in the manufacturing of electronic devices. The quality of soldering directly affects the performance of electronic circuits and devices. Excellent soldering quality provides good stability and reliability for circuits, while poor soldering methods can lead to component damage, significant testing difficulties, and potential hazards that prevent devices from functioning … Read more
A certain audio product’s PCBA (wave soldering process) experienced burning during use. The failure rate was high when using Flux A, slightly decreased after cleaning, and dropped to zero after switching to Flux B. This article will explore the failure reasons through a series of professional testing and analysis methods. 1. Visual Analysis From visual … Read more
