LQFP128 doesn't work when cold

You don't say anything about the appearance of the solder joints themselves. That would go a long ways towards identifying and possibly resolving your issues. Heating and cooling could affect performance if you have a/some cracked or otherwise loose

Our MOLE was the same way. Setting it on the floor was the best way to cool it down. I'm not sure you're ever going to do much better than a factory shielding box unless you just build a bigger one and put the whole thing in it...profiler and facto

I sewed a sock out of a Nomex/Kevlar blend fabric because we had the same problem with our profiler. It works great. After one run through the reflow oven, the internal temp rises by about 5 degrees C. It used to go up by about 20-25 C. I can pic

Found the aramid fabric (Kevlar) on the website you suggested. Which thickness Aramid-and-Fiberglass Sheeting should I get, do I need to buy a strip as well to protect up to 600F? I was going to use PTFE-Coated Fiberglass Thread as it is rated up to

Glad to hear it is running good for you. I have my new wave solder machine in house.(hooking it up next week). I am debating between Sn100 and Cobalt 995 (metallic resources). Does anybody have an experience with the Cobalt. Or a reason not to go wit

Look here you dime store cowboy. Why in the heck would I ever contact you. You've done nothing, nor have you even proven that you are legit. Stop wasting bits on this forumn and either pony up with some useful information or go away. Jay

Problems with SN100C in a Soltec Delta C Wave

Electronics Forum | Wed Jun 14 11:55:34 EDT 2006 | Rob

What rpm is the Delta wave going at? (I think it was recommended to have it running at 700-800 rpm even if you are not using it, otherwise you get a dip in the main wave) At least that's what I think I remember from a trip to their factory, but they

Thanks Davef, We recommend ENIG to our customers at this time, we have not had any customers reporting issues with it so far. I like the protection of the nickle from copper dissolution during wave in a PB free scenerio, but the "Black-Pad" issue i

Oop's Pb BGA's in a RoHS process?

Hi Grant, I can't speak for reliability, I don't know how your boards are going to be used or what alloys you are using. As for RoHS compliancy as far as I understand the cut off if July 1. So any boards sold before that in the EU are OK. Best regard
