Many components can due to there thermal sensitivity not be soldered with a traditional wave solder process (LCD displays). Other PCB’s are due to SMD component layout issues also can’t be soldered successfully using the traditional wave solder process. Further more often the very costly custom made solder masks to cover the SMD components are difficult to make and not justifiable so customers finish up hand soldering parts. To automate this process the answer is selective soldering. Ebso already had machines like SPA 250 and 400 developed in the year 2002, this machine concept also allows small to medium companies with smaller budgets and production lots to enter this attractive new technology. The SPA range of systems starts from manual machines all the way up to fully automatic solder centres.
