Oh, for a second there I thought it was 257 C, not F. Solder temperature! Still, one WEEK at 257 F seems way extreme. Maybe this is to bake out a part that has been underwater for a week. Is this a military part? I can't imagine any commercial-g

Thanks for the reply, how do people handle different packages then if you can't add new ones? If we had a 1206 sized inductor, then a 1206 sized ferrite bead and so on, they would all have to be grouped under the same generic heading? e.g. Chip-R321

> Don't get yourself a Sapphire!! Right, that has a whole bunch of nozzles, and I can't imagine how they can have cameras on all of them. Couldn't handle larger parts, the nozzles are too close together. Jon

Saw one at Apex last year, pretty cool device. Not cheap, though, as you've stated. Zarrow thinks everyone that's doing BGA should have one. O.C. White makes an instrument that does something quite similar, although I think it uses more mirrors and

Two BGA replacements (same location) and throw the card away is the rule we are following. Experience has taught us that anything beyond this and you'd be pushing it - specifically when your new PBGA's price is above $20.00. The biggest concern is

I can't help you with most of that, but heres a starting point. "L013: 2nd limit over" means that one of your axis is showing outside operating boundries, as in placement head is too far forward. Make sure all your devices are not pushed out to thie

Jim: I have limited knowledge, but here's what I know: 1. Yes, it's a standard process. In today's SMTNet, it's rarely mentioned, and few people reply to postings. 2. Nope. It's a "specialty" piece of equipment for most CEM's. Depending on you
