Tin appearance on PCB boards post-wave soldering may arise from various factors beyond just design flaws. Issues like inadequate flux activity, uneven application, or uncontrolled solder temperature can contribute. While not all issues stem from design, designers must ensure correctness. To mitigate tin formation, focus on flux activity, wettability, and solder temperature during wave soldering.
After copper-clad laminate processing for PCB assembly, various electronic components are assembled and connected through soldering techniques including wave soldering, reflow soldering, and manual soldering methods.
The initial stage of wave soldering in PCBA packaging is crucial for quality control, involving steps such as pre-drying to prevent PCB warpage, adjusting preheating temperature for optimal solder fluidity, and determining transmission speed and angle to ensure even soldering.
