Probably very far-fetched, but I can think of a scenario like this: - machine picks up a component - between vision and placement the part is lost, but the loss is not detected due to oversize tool, which causes the amount of vacuum drop to go unnot

Hi, Yes, that's an idea, but from my experience with MYDATA, it would fail test, and the machine would either know it's lost the component, or it would not know, and the component would not be on the pad because the machine would think it's mounted

Since these are mounting holes, they're probably all the same size. Why not try rubber plugs shaped like golf tees? Try: * Dempsey Industries; 802 N. 4th St, Miamisburg, Ohio 45342; (937)-866-2345; Gary Pascoe * Shercon somewhere in CA * Harman; 36

Could I get some help please? I have a Heller 1700EXL, 7 zone oven and I'm trying to figure out a better way of off-loading my completed boards. What I have now is simply a small table at the exit of the oven with about an 8" drop from the top of

Hi Harrit, We are processing SMT eleco's normally - up to around 8mm in height, the larger sizes can still be avoided and are through hole as the cost of them outweigh the benefit of surface mounting them (although we did get good results on test fo

Hi CW, Larger chip caps can be susceptable to cracking, but mainly this is due to handling - flexing of boards is the main culprit (the part being mechanically joined at both ends to the board). PCB's usually flex easiest along one axis, and larger

EMI shields are no fun! Your process will depend on your design and condition of the shields. We always break the shields into their own process. Because the shields are never flat, screen printing paste and trying to reflow them only caused huge

Hi, I'd be inclined to go with the through hole capacitor, as to surface mount it you would probably need to go for an elco (ceramics & films don't do that value in that voltage, & you'd be hard pressed to get a tant in that voltage). SMD Elcos a

Q: If you do not use a selective wave pallet does this not leave the possibility of solder flowing up thru the Via's on the board? A: No. Your board house can cover your vias with solder resist. Your board house can plug the vias. You can cover t

Hi, I take it you are refering to intrusive reflow? It came around as more components became available in surface mount packages leaving mainly connectors left over for a separate insertion operation & wave/selective/hand solder. Manufacturers imp
