| I am experiencing a problem with a surface mount coax connector that over time pulls loose from the PWB. The connector has 4 small gold plated leads and we are soldering it to a flash gold board. A cable plugs into the connector and puts some con

| 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 inor
