hello Zac, if you are running pump at 100% and there is not enough wave then you will probably need to empty solder bath and clean everything. also check pump parts for tear and wear. eached solder inlet can make a lot of problems when it comes to w

Hi Zac, In looking at your photos, you may not be having a problem with your machine, but with the solderability of the PCB. I've zoomed in to an area that looks to me like the solder has de-wet from the pad. The leads appear like it almost has a fi

I agree. Trim the leads before insertion, then raise the pot height. With the information given, this is most likely your solution. Our machine has a dam wall on the rear of the solder pot that raises the height on the solder pool. I would make sure

Thanks for the suggestion, Steve, I'll look into sourcing a test kit here in Oz! I did however talk to the guys doing the touch ups of this batch of boards and they are sceptical that it's nickel: they have had to solder to nickel in the past and rec

I recommend examining the problem pads and a representative bare board using SEM/EDS to determine if the problem is related to a board solderability issue. I can support this type of analysis (www.semlab.com).
