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

Jay---- Please contact me if you are interested in the new alloy that my firm, WCS, inc. has invented. Bahodim (TM) solder is successfully being used by a startup in Florida, Initech, inc. Bahodium has out-performed SAC, Tin-Lead and SN100 in re

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

Hi, Do you mean selective palettes in the wave? We are running those, and it makes the process window tight, but once we got there, it's great. Pre heating the board was a bit difficult, but we got it right, and went for a water based flux. Not sure

Which processes are out of control here? Do you ever have any input? YOU asking for updates? what the hell for? You don't even know what we are talking about! Man, thing, lady, whatever, you are getting annoying! And yes I know I just encourag

We have a board calling out for 50 micro-inches of nickel over 30 micro-inches of gold. This is a solid gold board on Rogers material. ENIG cannot be deposited that thick right? Electroplated gold (we thought) was usually 35-50 micro-inches and was

Yes you can solder on to it - just tried it with some 0603's across some gold fingers with tin lead paste & a heat gun. Don't know how many times you could rework it though. Any chance you could get hold of an aold populated board from your custome

I believe this is a MELF, correct? If so, it could be your pad design. Most use a "horse shoe" style that seems to work well. Another thing to look at is your cooling zones. I've seen these parts remain liquidous into the cooling zone where they

Yes it's definately possible to have too much flux. You'll see a white residue film on the board. In the past we have had hipot issues cause of too much flux residue ,left on the boards. You defininately don't want to be using a no clean flux and sti
