Folks, Thanks for all the info and suggestions but let me add a bit more to the pot. Our products work in a harsh environment and are classed as safety critical. Customer returns are our biggest concern, we don't get very many and feeling here seem

I guess you're adding the gas to keep the fingers clean - sounds likeyou got your threads mixed up on the Forum. Any way I would suggest not doing this. Gas is pretty flammable. I have pix of one our Hollis cleaning machines going up in flames cau

How much flux will be lost if you do that? And I would think that the paste would be too dry by the end of the shift. And don't forget that power rating of the oven doesn't mean that it is using that much power the entire time it's on.

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

Using no-clean flux will make the boards very difficult to clean. If you can switch to water soluble flux, your life will be much easier. The "icicles" lead me to think that the board isn't getting hot enough in the pre-heat cycle, and/or there isn

There a few questions that I have for you. 1. What type of flux are you using? 2. What temps are your preheaters set at? 3. Can you possibly place them on after the wave? The reason I'm asking is that there may be some adjustments to the wave to bur

I agree with SOB. First, someone is thinking too much and has too much idle time. And second, controlling volatiles from routine fluxing should be much more concerning than volatiles from out-gassing from delamination. In most plants, delamination is

We saw your profile, which in my opinion looks alright based on the guideline from the vendor. Can you tell us more about the joints that you cleaned? Are they showing nice wetting and nice and shiny finish? How about your stencil thickness? From my

We too use both Water soluble and No-clean in our shop. I can tell you that we have won 6 different contracts from other local contract house because our boards "look pretty". It's amazing how some customers judge how other houses build their board
