A huge help in the very first statement, Josh. And yes, fixed vapor mass in the machine I am currently evaluating. OK, and a machine that can change the vapor volume based on a calculation of mass of the assembly sounds logical. (whirrrr,click... a

I worked for a medical instrument manufacturer a few years ago and we had to calibrate all measurement devices. That included everything from our vapor phase oven's thermocouples to 6 inch steel rulers. I don't see any logical justification if you'

Major advance: Productionization of SMT. Minor advances: * Realization and control of solder paste characteristics * Vision alignment controls in printers. * Evolution from mechanical centering [through laser alignment controls] to vision alignment

How large of chip capacitor can we use reliably? I��ve heard they tend to crack. I��ve also heard if you pre heat the larger chip caps (1812 and above) before vapor phase reflow, they won��t crack. If I use 2 mil copper for a power supply board, a

Simon, In a previous life, I came upon a maintenance tech that had an old vapor phase oven control cabinet half ripped apart for a main power problem. I asked him if he had checked to see if any of the E-Stop swtiches had been hit. One had been ac

We are using VPS, but only for high mass assemblies. As the other respondent has suggested if the mass of the assemblies is very low then difficult to control temp. rise times to within the normally accepted parameters. The Rehm equipment does seem

Hi Jack, I haven't progressed that much on the reflow project.I'll be working on it in two weeks. Although, I have few vendors that I've been communicating for more info about vapor phase reflow ovens. See the following list: Wenesco Sintronex AICT

Also please contact Rehm Thermal, they make best Vapor Phase systems in terms of cost of onwership - less galden usage than Asscon or IBL, have more controllable ramp rate control vs the other vendors also...use patented galden injection on demand an

Shannon, We have been using VP for all of our lead free production since 2007. Here are the items I can think of off the top of my head. Pro's - small footprint, minimal profiling needed once machine is understood, oxygen free soldering process, s

I don't fully understand what you are trying to do... 1. Reflow Solder in a Vacuum Temp Chamber 2. Vapor Phase / Condensation Solder with Vacuum 3. Contact Heat system with Vacuum 4. Inline Reflow Oven with Vacuum ... or what you are trying to sold
