| I am running a board that is .062" thick and has components that over hang the edge of the board by .090". I have bottom side smt components (chip caps and resistors only) and use the turbulent wave to help solder the components. The problem I am

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.

Good Afternoon, How is the stiffener adheared? If it is laminated to the flex, it may help you with the surface planarity through reflow. If it put on with PSA, it may cause more problems then it would solve. PSA gets soft through the reflow. It may

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

I have some 13" long boards that warp considerably during first pass through reflow (no center support), what I've done to improve this type of warpage is stiffeners along the front and back edge. This may help with twisted boards as well.

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
