I have used the Quick ? from I don't remember what company. But it was a smallish machine ie about the size of a washing machine. The heat/cool cycle was about 30 to 45 minutes. every thing had to be properly sealed or you would loose vapour, this va

Agreed, but his fiducials aren't working so he may have to resort to something a little bigger that returns a more consistent pattern. You are correct, this will provide less accuracy than his fiducials but will save him the expense of cleaning his

We are Currently running a Board and it seems that the SOT-223's on the bottom side have flux and water trapped under the part. Nothing has changed in our process and this is the only board that it is happening on. We are using Kester R562 water wa

RLM, you have been very helpful! Let me try this on you: We have two IVC's, one with a conveyor and Quadalign, the other with a workholder platform and Cyber-optic. I just ran the first successful assembly on this second system, but the extents had

Let's be more specific. Why do you need to clean the boards? I assume it is for testing purposes, probe contact concerns and the like. This is the only economical reason I can think of to clean no-clean flux residue from your assemblies. Before y
