If speed is truly an issue, migrate to no-clean. However, this is not always an option. Why bake after 1st smt pass? Because you are probably not drying completely under the BGA components, and/or you are pushing water into the parts/boards/ vias

Vinit- The name's Rick by the way. Probably best to stay in the new equipment business as your knowledge of used prices is a bit out of whack. First of all you could buy (2) CP4-1's new for what and FCM went for new. Second CP-4's are selling for ar

Hi, Your right guys, and we turned off the chip wave, and most of the problem went away. It looks much better, and we are getting a slight bridging on a USB connector at the front edge of the PCB and a little adhesion, but not any where as much as w

Samir, why do you bring back such idiotic rubbish between two gentlemen that just happen to fall into their presidency? It is not rellavant to the questions at hand. I agree that ultra sonics can clean better but do take longer IMO. As for stencil

~le sigh~ makes a good point about forcing bent leads into the solder, letting the solder cool, and releasing the force on the lead. On the other hand, reforming leads of components prior to assembly is dangerous, also, because the "bending of a lead

If he is the same Martin Gershenson who works for Christopher, then I'de believe he's being sneaky. We demoed one of their units three years ago, along with Mirtech and YesTech. Of the three, they were the only ones who wouldn't let us experiment w

Impact is the instantaneous force at the time the component first reaches the PCB. F=M*a....so the acceleration is the key factor. If charted on a graph it would look like a spike...higher force for a short duration. The placement force is typical

I'd have to agree with JAX here. This forum is intended to be a "Technical Bulletin / Newsgroup" and nothing else. Truthfully, these posts of the "old-timers" announcing their departures is getting..well.....OLD. I hate to see the Old-timers leave
