Hi, I am looking for land patterns for 0612 and 0508 chip capacitors. Because they are not standard (yet) package sizes, i am having trouble finding a standard land pattern. (If you don't know what these are, picture a 1206 or an 0805 with the te

Has anyone caried out a DPM analysis on these components. I would be interested to know the defect rates and other assoc. placement issues as we have never placed them before. Thanks, cath

Our SMTproduction has next troubles : 1. irregular 0603-components in tapes (different solder shapes) makes vision errors on placement devices 2. big solder amounts makes pickup and placing errors 3. some tapes delivery delays , so production halts f

Epoxy is hydroscopic. A cavity will form when the cure furnace reaches the boiling point of water. The steam expansion creates the pocket. It can be large enough to be filled with molten solder from the wave machine and cause a hard short under th

Hello, We've just started using VIGON A200 in our Aqueous Trident XLD system and observed that aluminium electrolytic capacitors get corroded. Concentration was set at 20% and washing is done by spray at 150F for 6 to 8 minutes. Then is rinsed seve

First, you cannot measure capacitors once they are soldered onto the board. Second, why must you measure? Verify your machine set up by using intelligent feeders (if your machine has them) or a checklist, preferably by two people. If you cannot trus
