The development cycle of the company I work include building alfa prototypes, sometimes in breadboards, and beta prototypes in printed circuit board assembly.
A considerable slice of the development time is wasted waiting for PCBs prototypes to be builted by PCB manufacturer here in Brazil. Since the time spent is a lot, I'm thinking in ways to somehow speed up the production of these prototypes in my company.
Do you have any suggestions or experience that you'd like to share on this particular subject? Maybe some cost affordable machine DIY to build PCBs at home?
