So you have solder balls at the outer edge of the part right where the pad goes underneath? If so you just have too much solder but I wouldn't worry about them. the solder usually does not wet to the edges of these parts because of the exposed copp

Maybe the issue is how the feeders are being unloaded. The operators should leave enough covertape to reload the reel onto a feeder without component waste. If the issue is some parts are exposed in the feeder then you will most likely loose those p

This will depend on the feeder design. Some feeders cause a loss of several components when removing a reel from a feeder. If yours do not, the operator should be able to leave enough tape and mylar cover tape for this reel to be put back onto a fe

I think this can be of help when dialing with setting up feeders for product prototyping, where often we have to dial with a short quantity of components (often pieces of carrier tape w/o tape and cover leader) just enough to run (if lucky) those few

97% to 99%? I've heard of one company that managed that but only after a big six sigma project. And they had minimal stock anyways. I think if everyone picked 100 components to cycle count, that the average accuracy would be around 80% . That is

Don't know if this applies to you, but here's my 2 cents. We just pick up what parts from that reel that falls off with mylar take and tape it right to the reel. That way, you can use it for rework or whenever you need spare parts. As for the tear do

Hi Bert, There should be an action occuring when the machine hangs-up(ie: Q motor rotating, getting ready to change nozzle, or other action). See if you can find this. The first thing that comes to mind is a loss of the signal for a nozzle in the

Hi, has anyone got any experience of automatically dispensing any of the following adhesives? Loctite 5366 Loctite 5145 Loctite 431 We're looking at using one of them for assembling two parts of a polycarbonate moulding & having trialed them (and

I agree with JME... You really need to do your homework when it comes to verifying if an AOI machine, or any other machine, will meet your requirements. Be sure to check out MIRTEC as well. Thes guys have got a very good name in the industry. My

we have more of a problem with transfer of salts from skin onto the products. Oils ect can be cleaned off in our solvent based cleaning system which we put everything through, but the only way to remove salts is with warm water. And we dont use a wat
