Hey Peterson, Just as another resource, I've seen Circuits Assembly Magazine post equipment surveys in their website. I believe there should be a link on their site at http://www.circuitsassembly.com The survey index I noticed was at http://www.ci

All of these machines are excellent. Each has survived the test of time and abuse to hold unique positions within segments of the industry. So, your question is difficult to answer without proper framing. It's like asking what is the best vehicle.

Assuming the criteria being which would perform the best in some type of demolition derby, I would rank (from 1 to 5, 1 being the best) in the following order: dump truck, school bus, Mini Cooper, Caravan, and then the reliable Toyota Camery. Sorry

If you are concerned with the actual temp of your pre-heater verses what the machine's display "says" the temp is, use a calibrated digital thermometer and place the thermocouple probe inside the pre-heater and next to the machine's thermocouple for

Dear Pete, thanks for the reply. My calibration procedure says pretty much what you said: variance of 10 degrees F. I am having a temp. swing of close to 80 degrees F. and no matter how I try to situate the thermocouple back into the preheater, I ca

PCBA baking prior to rework

Electronics Forum | Mon Oct 14 18:27:38 EDT 2002 | kennyg

In regards to baking an assembly prior to hot air (BGA) rework.... 1) Do people always bake, sometimes or never? Does this depend on whether MS sensitive components are near the rework site? If a BGA is to be removed and reballed, baking is a no-br

There is not requirement for a low O2 atmosphere for no-lead soldering. There was quite a lot of work on lead-free profiles in the European IDEALS lead-free project and some info on this is available for download at: * http://www.lead-free.org/down

This is for Pete. He's very busy today, trying to make money to feed the wife and kids. Why doesn't the new SMTnet "home" look like the old "home"? * New "home" has like three boxes that each go all the way across the page. * Old "home" had like si
