Is it possible to achieve a 100% top-side solder fillet where pin 1 on the device is attached to a ground plane ? we've optimised the wavesoldering and fluxing operations, but without much success on that pin, every other pin is fine. Any advice would be gratefully appreciated.

Generally the answer is yes. But there are many considerations. First a couple of questions 1 what flux are you using 2 Do you have top side pre heat in your wave solder machine 3 what is your measured top side temp. 4 what is your dwell time in the wave. 5 does your current results meet IPC 610 (you don't need 100% top side fillet in most cases!)
