Point one -; I am also having this concern but based on the DPM it's getting difficult to keep the track to understand what exactly happened with the particular PCBA (Attrition component placed or Cleaned PCBA due to some issue those components are p

Usually board house should inform you of these. Here supplier works differently. We generally don't get these updates. Only the ODM or customers get. We only find when we are facing any issues. Can you please enlight me on how to check the value

Thanks for your input. I do understand from this thread that OSP is the issue We don't have options left. Need to use this. Defect rate is just 0.002 still I am focusing on zero defect product since this will run for longer period. Kindly provi

We have a vintage 2007 JT wavesolder machine that we are having troubles with our solder pot heating SSRs not energizing. Please see the attached Word document that gives the details of our troubleshooting. I suspect that the TCM has gone bad, I co

It's a BGA component. Missing ball is not possible because we have enabled the vision in pick and place. Solder paste is OM353 type 5 Possibilities of Flux dry before reflow seems valid but I saw the board data it was completed on time like other

I guess my question would be why are you getting so much/leaving so much flux on the boards during the select solder process? With a drop-jet fluxer you should be able to apply the flux very selectively and leave a fairly clean looking PCBA, assumin

The problem that we have seen applying NC flux (EF2210) at selective solder is that the flux overspray (relative to the nozzle path) did not see high enough temperature to activate the flux and turn it to a non-conductive, benign residue as one would

In particular we are looking to measure the repeatability of the voiding measurements for thermal pads on QFNs. There is some concern that given the nature of AXI programming with upper and lower boundaries set by a programmer to detect a defective s

Have you tried rotating the board 90 or 180 going into the oven? With inductive components there's a possibility of magnetic current buildup, that pulls the component to one of the pads. Although, I've only seen it on larger inductors. Also, the pres

Looking to power up this board with 3v coin battery. I've tested this board with it and it works but to solder this on or make something that has clips for the attachment to power this up. Positive and negative connections are the circles on the inne
