At the international Resistance Welding Seminar in Poland, welding expert Dr Marcin Alexy, explained that the electrical contacting of printed circuit boards (PCBs) can be a challenging joining application.
The electrical contacts realized by welding must fulfil following key requirements: low electrical resistance, sufficient mechanical strength, high thermal endurance and good corrosion resistance. These properties must stay stable within narrow tolerance window over the entire life cycle of a product. The good news is that the requirements needed are very well met by Resistance Welding.
