As the demands for performance and quality in electronic devices continue to increase, PCB soldering technology is also evolving. Whether for single-sided, double-sided, or complex multi-layer PCBs, the precision of soldering directly affects the final product’s reliability, longevity, and performance.
This article explores high-precision PCB soldering technology from basic to advanced
Why some PCB solder service life is short? They are occured bad welding phenomenon after a period of time led the electric device bad.Today, let's analyze the main reasons.
PCB poor welding analysis:
PCB surface pad or SMT be oxidated lead to poor solder.
PCB has dusty or oily materials on
In round welding order.The device of welding sequence: resistors, capacitors, diodes, transistors, integrated circuits and other components of the power tube for small to large.
Both the chip and the base have a direction,The welding should be in strict accordance with the PCB board gap with the direction of
