We just use stare titanium stiffeners from the wave soldering area. Titanium is probably over-kill for your needs, but will work. Sources for titanium stiffeners are: * APT 603.622.1211 Tom Dimagio * New Era Technology 603.669.77971 Jessie Ward * B

I used to have the same issue with reed switches on one product we ran. Same oven too. We ended up rigging up an "umbrella" with two titanium stiffeners and bare PCB as the roof. It was hokey but it worked.

A reflow oven with Center rail support can help. If your volumes are too low to justify spending $$ on a proper carrier, titanium stiffeners applied to the PCB before it goes into reflow is a cheap, albeit manual solution.

We run stiffeners on all of our product through our wave solder process and most of our product through our reflow and adhesive cure oven. The problem is we continually put on and take off stiffeners because of poor reliability of stiffeners staying

When we have warpage issues we use Titanium Panel Stiffeners even though the stiffeners are mainly used for Wave we find little issue for reflow. Mind you the boards have to be large enough.

Kelly, How are you cleaning the stiffeners? The Smart Sonic cleaning process has been very successful in such applications. Visit the Smart Sonic Web Site at: www.smartsonic.com Or call me at 1(800) 806-440-R. Regards, Bill | We run stiffeners

You can try putting titanium stiffeners on the PCB to prevent it from warping. How thick is your stencil? More paste would give you a wider window however too much and you risk bridging. You could try over printing the pad at the heel and toe to get

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 h
