| Folks, | I am interested in knowing what level of Nitrogen purity you are running in your reflow ovens for standard SMT assembly? | It seems over the last several years people are increasing the Oxygen level in thier reflow oven atmosphere. | What

| I am looking for some guidelines on evaluating solder paste. I am specifically interested in No-Clean Pastes, as they are a completely new ball game when it comes to slump, tack time, stencil life, tack time, etc. | Thanks for any and all help give

Checks calendar ...nope not April 1st. -The fresher the paste the better the solder joint. Agreed - My dilema here is upper management wants the two lines to share one stencil printer thus saving the cost of purchasing a second printer. They propos

| Anyone using hot air nife for wave soldering process. | Does it work? | Does it really eliminate solder bridging and does it create any other problems? | | any feed back will be much appriciated. | | Thanks | | Tony A | | Tony, The hot knif

I did some investigating and it seemed that getting a reflow oven with an inert atmosphere could be the answer to the inconsistant wetting issues that we are having with a leadfree DFN-10 on one of our products. Here's my question(s). It seems that

Hi, it is not necessary to store MSDs in nitrogen to stop them absorbing moisture, just a dry environment. Nitrogen storage is good for storing devices for many years as it reduces the oxidation of the solderable surfaces. Best option for storing MSD

So we have 3 new ITW/EAE Centurion ovens that all have issues when running nitrogen to keep the o2 ppm below 1000. It is always much higher, sometimes gets lower when no boards are loading in. They've had us replace valves and do an upgrade kit that

Jason: How did you determine that the deposits are tin oxide? What does this stuff look like? Klein Wassink "Soldering in Electronics" (p. 221, quoting original work by others). States (in effect) tin (or solder) quickly forms a protective oxide
