Dave has stated the caveats well. I too have similar experience in reworking BGAs that mirrors your own. The only situation where I saw this as an issue, was in memory devices where a row of BGAs might share a commonm heatsink. In those cases the

I used Indium WF-9940 at the last place I was at for 5 years. We ran leaded and lead free product in our ERSAflow selective soldering machine with that flux type. It worked good for both applications. The place I am at now we have an Ersaflow selecti

Hello, I have recently obtained a trial version of Mentor Graphics' BOM Explorer. Has anyone had any experience using it? We are currently editing our BOMs manually for P&P machines programming. After quick look and trying few options it doesn't see

The conveyor is programmed to turn off the belts and go into an error condition after 30 seconds if the board has not passed the output sensor on the conveyor. The intent is to indicate a board jam and prevent damage to the board or belts. On convey

We have a Philips CSM84VZ which we acquired several years ago. It has been running fine until recently when a new employee ran it unsupervised. Since then, when in run mode, it wont't run, but just displays error code "#79:operation interrupted". our

The machine does not have pre-heating feature. I'm soldering a six-up panel...I've tried putting them a an oven and letting them soak for 20 mins or so at a low temp. But by the time I placed the panel in the machine and manually fluxed the top sid

When you get in to a 30 spindle lightning head or the dual and single beam 7 spindle flexjets from UIC, there generally really solid machines. The only flakeyness we have is with a GC120 (4 beams in 1 box). and of that most of the issues are purely b

Hi We found the misalignment sometime during SMT 0402chips. So, we made the pick up speed a bit slower then the condition was better however it was time-consuming and delay shipment. We r using Yamaha 100Xg SMT M/C and no probelm in mounting 0602 o

I want to start an assembly that may require use of SMT machines such as SMT assembly, bond wire, Xray and PCB fabricator machines. I apologize I am not to savvy with the technical names such as the above but I just want something not to costly or e

Yea, it's tough and takes 25 disks. Not sure if there's a better way. As for NT, we bought NT upgrade packages from Speedline for all three of our AP25's. The backup is then done on a CD burner. I can't remember the cost of it all. However, be a
