Hey there, trying to get soem useful data on joints that suffer from gold embrittlement. Anyone got any data on effects ont he electrical conductivity of the joints over time? does it degrade quicker than a normal good joint? (let's all ignore the fa

Are you setting up double side PCB that has the tall components on the bottom that being push up by the support pins... ??? Or because your vacuum is leak and not holding the board at the same spot every time you are loading the board.... Board warp

I would think that you could quite easily use 0.6mm I/D nozzles even when using a hand syringe. As you say you are only using this for larger devices to prevent them from falling off. I am sure there are very reasonably priced small compressed air un
