Thanx a lot for advice... My only question is: did you had troubles with prehaeating of the boards? I heard it was the only critical point due to chosen technology, infrared preheat (if it's still IR). I allready checked Vitronics Soltec and IBL,

I've worked with a Vapor Phase Oven a semi-automatic and a manual oven for evaluation. They worked fine and produce better grain of solder joints. The fluid that you need depends on the solder temperature that you require. I've used a 200'C fluid for

We do not have problems with preheating. before we used to suspect that the cause of tombstone was that because the semi-auto and manual version do not have pre-heat stage. We had 1 with an IR heater and it is quite okay. you can use it too to cure a

Hi all, I'm having issues placing 7 pin DPak packages. I'm using mechanical centering with four centering phases (one for each orientation). Tool used is A24S. Machine picks up the part but will reject it when centering the part. I have measured all

Usually the reason it will fail a part like that when you are using mechanical centering is because the part is usually picked so off center because of the body shape. So when the centering jaws close to push the part to center they give up and fail
