Power Jack installation problem
Posted: Tue Mar 12, 2013 9:10 pm
I recently purchased 5 RBBB PCB's only and have encountered a problem. Either my 2.1mm power jacks have too large a terminnal or the thru holes provided were drilled too small. Each of the three terminals on my power jacks have a small hole at their tips. In order to get these terminals to fit the holes provided I had to grind the terminal width to the point where each of these tiny holes were ground away or lost. I've used these same 2.1mm power jacks on numerous other projects without issue and they are identical to similar jacks found on all the other project boards/kits that I have purchased and build. I thought about drilling the holes larger but was unsure what that would have done to the thru plating present. Since I have 4 more PCB's with the same upcoming problem what should I do? Is the 2.1mm power jack used sourced from a known supplier and if so who?
