One diagnostic tool that I have found useful in the past is the "hot plate test". Place suspect components and/or PCB's on a hot plate and turn it on High. Then observe. Granted the conditions on the hot plate are not the same as in a reflow oven,

Hi, Yes, I think this sounds like a form of tomb-stoning, and we used vapor phase until it ended up driving us totally nuts trying to deal with tomb-stoning. We tried everything, and all kinds of stencil apertures. Vapor phase is an amazing process

Just been quoted GBP500 for 5kg (2.7L) of Galden LS-230. Don;t know if the lower temp non-leadfree stuff is cheaper If anyone in the UK has a small qty they'd sell me for experimentation, (e.g. old non-leadfree stuff they no longer use) please get in

I've some troubles with LGAs components. i try to create void free results. so far i have no problems with dpacks, i think i do something wrong with the vacuum time. The padcoverage of my lga is very bad the vacuum creates solderballs under the compo

Steve, If you can get me your snail-mail address, I will send you some latest information. We actually have a totally new system called Delta 5. It is Condensation Soldering rather than Vapour phase, the difference being that we solder in an air ti

Perhaps a little hard to find but is there anyone who uses a vapor phase process to solder populated card with BGAs. I am interested in the success rate of such a process. It is obvious that the throughput is reduce vs a convection oven but still thi

Is the mechanics ok with the raising and lowering into the vapour ie no small movements that could be moving the part ? Most Vapour Machines have a lower and raise mechanisim so movemnt of parts can happen if not smooth, especially when coming out o
