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 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 having is that in order for the turbulent wave to work properly, I sometimes get solder on the over hanging components. If I turn the turbulent wave down, I will get solder skips on the bottom side. I have tried using a titanium stiffener but there is no room to clip the stiffener on the board securely. I suggested putting a breakaway on the edge to compensate for the rise in the turbulent wave, but I am getting negative feedback from design and purchasing. Before trying to justify ordering pallets, is there anything else I can try? I want to try not to add any additional labor to the cost. | Rob, | I use board shunts. They do nothing for stiffening but they work well for masking connectors. They are hi-temp rubber with slot cut in them to slip on (.062 or more or less) and they can be cut out with razor knife to conform to local components. Remove material as you wish. Pop it on when loading and pop it off when soldered. I cut two or three so that I can keep that many in tunnel at same time. Wave operator can install them as he checks components. They are dirt cheap (I'm still working with samples), pop on and pop off, and you dont have to worry about Kapton or solder masking.
