All the comments that have been made a great but I do have to say that much of the problem comes back to the design engineers not designing for manufacture. Centre board supports would have sorted the problem without jigs. | | I am running a board t

We do not have experience soldering to the PVD surface you plan to use. We use Titanium [Ti] stiffeners in wave soldering and our wave equipment manufacturer uses Ti fingers, nozzles, pump blades, and other parts, because solder doesn�t stick to Ti.

| A rash of new products here at my company have designs with multi-pin connectors 90 out-of-phase (orientation)wiht respect to wave direction, which has lead to massive bridging (shorts) problems.... | | Does anyone still use the 45 Degree Pallet

Is this a single sided or double sided board? We run the first side flat on the oven belt this keeps the board flat for the second side assembly. If the board warps during the second reflow process we will make a support fixture to carry the PCBA
