Just want to ask. What is the effect of dull gold surface on solderability? When I made a test run with several pieces containing dull gold defect on the pad(of varying levels), I found that components can still stick to the pad with good amount o

We agree with you. Recognize that these new solder connections have less metal and a lower standoff than similar BGA solder connections that have not been reworked. This could reduce the reliability of your product, somewhat. Flux or gel may be use

If we were to apply a thixotropic gel into a keep out area what would the removal process be? We have keep out areas that are later used for mounting purposes so the customer requests no residue in these areas. As I previously stated, we're using mas

You definitely have to be careful with unsealed components and markings/labels. The best you can do is check with datasheets or find an extra assembly to test it out on first. You can also try slowing down your inline to more like 1-2 ft/min and se

Water soluble process, yes. The machine is old and fixed at 4 ft/min by someone way before me. Looking into ways to reverse that to allow for adjusting the conveyor. Trying to determine how the contamination gets onto the boards. So far testing has i
