John, The first thing to check is how tight the boards are being held in the conveyor (assuming you are using a finger conveyor). They should be a little loose at the input end so there is some room to expand. If the boards are held too tightly, when

Tony: You have choices: * Hi Temperature Tape: Go with Wolfgang ... too tough to control. * Selective Soldering Pallets: Some like 'em some don't. A lot of your success depends on the pallet fabricator. * Screenable Temporary Solder Mask: Wol

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.
