Hi there, where can I find some hints about placing the temperature sensors on the pcb when determining the reflow profile? I'm interested especially in the case of a pcb having BGA's. Thanks for your answers ! gheorghe

Viscom is still there if in case you want to try the algorithms, we are already using them for almost 3 years now and the inspection stability and detection consistency are excellent.

could you elaborate on the type of component involved to help us understand the issue better....if this assembly is a special case you might try vapor phase soldering of that assembly...although that is a capital investment if you are not currently s

Home plate design is great for avoiding beads and tombstoning in some cases, but it will not help you when the spacing is too far apart. It will make it worse. You need a good even screen and accurate placement.

Does anyone have any experience in using solder scavenging systems? We have very tight land areas for RF shields (nearest component can be 2mm away in some cases). We are aware that both SRT and AIRVAC have such systems. Thanks! BWET

Just in case somebody will bump in the same situation and looks for a possible solution, the problem was with a small 2 pin connector that feeds one of the W DC motors. The connector looked ok, but one of the pins pulled a little out and was making

I heard of a new technology from OMG that helps extract more solder from drossing, I believe. I don't know where you're located, but my OMG contact is Jim Gilbert (Jim.Gilbert@omgi.com) in case you are interested.

We apply temporary solder mask off line, using a programmable dispense head. Works fine. Purchasing a placement machine with a dispense head usually only works-out well for the sales-type. Not in every case, but usually.

We have the same problems. We are using Universal equipment. In our case as I suspect in yours its a residue on the LED's not the machine.
