| Hope some of you out there can help me with this one. | I am getting feedback from our test department that they are showing opens on solder joints which have visually good wetting. The touch-up operators confirm that the joint looks good. All they

We use both F4G and MCS at the present and we are phasing out MCS. One main reason is that it's platform is not Y2K compliant. F4G is cumbersome and taxes a high overhead on your computer system. We have also found a bug recently when we have high

Re: Cooling

Electronics Forum | Sun Jan 24 19:53:54 EST 1999 | Steve Gregory

| It has been known that sufficient cooling after soldering is important in order to get a stronger joint during its solidification stage. And it has been so much emphasised with reflow oven. But, why many models of wave soldering machine do not come
