Stop and go is pretty standard and I have no issue with it...
Placing you off the track - Rev the nuts off it and give them a nice friction burn... |

I know we tried some of that new no lead solder with one of our kit assemblers for the purpose of trying ROHS compliance and we had several components fall off of boards just like this.(we supply another company with our components and boards and they assemble them), We said screw it and switched back. Just about all the components you get these days are ROHS compliant (Removal Of Hazardous Substances). When we first started getting them in we had problems like this even assembling them at our shop. We also use water soluble flux (in house) which flows different than regular rosin flux. Some times it just seems the solder doesn't want to bond with the tinning on the component. We started a vibration test on the boards now to try and avoid this. We finally solved it, but I wonder if that could be going on here.
