We have recently started up a vapor phase machine and no body can tell me what an ideal profile should look like. I preheat the board about 10 degrees lower than the melting point of the solder paste. The joints look great! Just have no documentation

Those cards are all different. The c-series stands alone by itself while a qsp2 and qsa-30 mount into a slot. They were all manufactured seperately for each machine. I would purchase a new refurbished one for the 2c machine and forget about the other

Melanie: We're with AVFOM. If you don't believe there is solder on the pads, use a beer can opener to pop the component off the board and you will have your answer. Easy-peasy. Who ever told you 'if there is solder, there is voids' in solder connect

After reseating the M controller boards I was able to get further than I had previously, no save status error, and was given an error about the voltage being wrong. During my last run my company had an electrician in to rewire somethings and put a

We find it is a bigger issue in the summer when there is more humidity in the air even though our facility is air conditioned. We've also seen similar boards go through the same process and vendor A has problems and vendor B doesn't, so fabrication t

Does anyone know if it is possible to change the distance that the squeegees travel? What i mean is... Is it possible to change where the squeegees start and stop during a print? Our squegees seem to stop right at the edge of the apertures and this

Hi All We are facing problem with solderability of BGA connector. After Xray we have found open under BGA connector. After removing from PCB it seems some copper pads are still gold. We are not sure why this is happening. We have 5 thou stencil and

I hope to get some feedback here. I have a SMD connector that reflow-solders quite poorly (I guess solder paste or profile issue). On the X-ray I see strange bubbles, does it mean there are voids under pin? Generally I am not satisfied with the sol

A good epoxy should work. Removal would require damaging the board, component, what ever it is attached to. I know Hardman makes a bi-pack ambient cure epoxy that we used in the lab. Search the web for epoxy suppliers, they'll offer various cure s
