I agree that wave soldering is probably your best method. Of course if you can, tin the wires in a solder pot before insertion into the board. The solder that would be there will probably facilitate wetting a bit better. If you absolutely have to

It is possible to use a selective wave soldering fixture to "mask" the BGA devices from the wave. Unless you have a very thick board or one that is tough to heat, you should have no problem with BGA. Of course you should run some process experime

Rob is right, you do need to dispense paste or pre-forms when using a laser. Although the Panasonic Soft Beam has a wire despenser. I've seen laser soldering and it does work on smaller stuff. Doesn't work well on connectors even after preheating.

A heat pump pumps heat. The poster was talking about pumping molten solder.

For what purpose you are looking at this electromagnetic pump? I am having a heat pump in my home. I know the bit about this pump but it is hard to maintain it.

One thing that you do not want to do is run a 240V oven at 220V. One place I worked a few lifetimes ago had an oven that had five top zones and only two on the ends on the bottom. It was something like 440V but supplied with 408V. It took a long long

Steve , I agree with all the responses you have received. Randy Villeneuve is absolutly correct in all of his assesments and I would consider him an expert with the process , Gris is correct about adding a "heat sink" to the process complicating pr

Bridging Causes: * Insufficient flux * Excessive pre-heat * High conveyor speed * Solder contamination

Hi all, If we are using non clean flux, what are the wave soldering parameters that we should monitor using SPC control chart? If not mistaken pre-heat is one of the important parameter that we should control.. Thanks, Sean
