Kelvin, Yes, we're referencing the same spec. I performed the test under the Class 2 conditions (except that I used a 100V bias rather than 50V...but my water-washed microBGAs still passed). Regarding the omegameter test: we have this instrument,

We have a Vitronics SMR400N oven and many times need to use N2 inerting. My problem is that it takes close to an hour of operation to purge the system to achieve the desired O2 levels (~40PPM). This is not only time consuming but results in an inordi

| We run stiffeners on all of our product through our wave solder process and most of our product through our reflow and adhesive cure oven. The problem is we continually put on and take off stiffeners because of poor reliability of stiffeners stayi
