Hello, I have an oven with a big fail. The Control Unit. It is a 5 zones oven (BTU VIP70)and has more than 10 years, and I think that now is not interesting to repair. I think to buy an offer, an oven Heller of 7 zones + cool,(better for lead free).

This may be worth checking out are you sure it is flux residue and not undercured plasicizers coming from solder resists due to the higher Lead Free temperatures killing the undercured resist, this causes many no faults found and bridging, solderball

We would be able to help you in any way that we can. There was an article in SMT magazine that explains a lot. Also, we have data on other processes that have successfully done this conversion. This has been a popular way of eliminating the conver

The fluxes involved with lead-free soldering tend to be more aggressive and the tip deterioration is a side effect of making the world a greener place. I am not certain if any of the tip manufacturers claim to have lead-free resistant tips. I would

I have this board that we are currently having problems with. When we run the BGA side with the hotter temp. the connectors on the other side lift off their pads. The BGA is lead free, that is why we have to use the hotter profile. Would it be

Does anyone know where to purchase 90/10 & Lead Free solder balls and kits for BGA Reballing? I'm having service problems with my current vendor who decided that they no longer wish to sell 90/10 balls, can't take in an order without a quote, and ca

For years all our R&D for high temp applications (automotive underhood electronics) has shown that Pb-free, at our max temps, doesn't have the reliability of SnPb. Fortunately, for us, EoLV (End of Life Vehicle) legislation in Europe was enacted bef

cman, Which placement machines do you use? What software do you use to program them? There are several solutions out there such as CAM CAD, Valor, CircuitCAM, whatever Unicam is called these days... I can't keep up with the acquisitions. None
