Just a thought, Solder flows to leads of parts and will tend to flow to hotest point. Im not shure but top side temprature might be hotter than bottom side. wouldent this cause solder to pull further up lead after leaving wave.

Talk to 10 people and you get 10 recommendations for pad layout. So far, here's number 3 [after IPC and AVX]. We suggest: * Use the IPC recommended standard. * Change from that standard when someone gives you a documented reason to change.

??? If you are referring to the SIPAD VIP, it is all done as a service after the bare boards are built and before they are delivered to the assembler. The whole board is reflowed during the application. Send me some contact info and I will call you

Double check if the part's rotation happened before camera or after (pre-rotation). Make sure no grease on rotation clutch.
