Fuji has said a lot of things in the past, then changed it later on. Just for the sake of argument....The guys that have trained me worked at Fuji for a minimum of 12 years. Not quite sure what Tech is talking about, but I do not recommend doing w

LIsten I'll have to diagree with you there.Now Im not the biggest expert at screen printing at my place of employment its a different department than wave which is my primary expertice but I see those UP20000 printers are always down with problems.

I agree with Russ. The problem is your thermal isolation is so small 1/16 inch. Also, most ovens measure temperaure in the plenum. You don't solder in the plenum. Therefore, you have a intermidiate "zone" temp. mixing between the top and bottom

Hypothesis #1: We agree with Steve. You are probably seeing the nickel underplate. The gold was absorbed into the solder in portions of a second, so that you don't see it is not surprising. We're guessing that the gold was porous and allowed the n

I say: �Wave flux needs to be heated to certain activation temps which won't be repeatedly achieved with a manual soldering process. Plus, you won't burn off any residual activator as you would if the board were immersed in a solder bath.� Muse say

Hi. I agree that the Soltec has weak, low-wattage preheaters, and also, the Soltec's fluxer is flippin' weak too. It doesn't do a good jab of atomizing the flux and getting good, huh-huh, penetration on the holes. I cranked up my Soltec's pressu

I agree with Stephen there! Or maybe we just didn't care enough about looking into it in the COLD profile days! Back to df: I don't think any manufacturer is going to give you a tolerance level, they'll stick with what they've told you -225. If it's

Agree!! Where is Your thermocouple-probes attacded and can we get the info from this? Delta-T of the comp. is very, very important! The single most important smt-process step is the profiling/recipy and as a result of this, this poor package will cor

Yep. If speed is not an issue a Heller 1500 will pretty well do you fine unless you are trying to process a brick. A Heller 1700 will not give you any more heated length, so don't get sucked in to that one. However, they are a little more fun to pl

I agree that it would be crazy to think that every part a company manufactured had to be re-engineered to allow for higher temps. Out of the question and I NEVER implied that at all. What I said was that Zarrow told us that it was alright to use lea
