The board, components and solder joints experience the separation process together. A tab…
Read articleIntroduction Pseudo soldering is a defect that can occur during PCB assembly, resulting in poor solder joint reliability. It happens when the solder paste or component termination oxidizes during reflow, preventing proper wetting and adhesion. This leads to weakened interconnections prone to failure under thermal cycling or vibration. This article explores the root causes of […]

Read articleIntroduction Soldering chip components like resistors, capacitors, and integrated circuits represents an essential skill for assembling printed circuit boards. While seemingly simple, properly soldering chips requires care and proper technique to avoid damaging delicate components or creating unreliable solder joints. This guide covers everything needed to successfully hand solder chip components of any size onto […]
