Thanks. Our older oven does have a basic PC interface but no SMEMA. Maybe I can write a short program for the oven's PC to pace the boards into the oven. I could interact with the conveyor's SMEMA interface via low-cost Arduino or something similar.

When we had a line that ended at an older reflow oven without SMEMA controls, I ran a momentary switch to the two pins in the connector. I push the button and the conveyor pushed the board onto the edge-hold of the oven. As a joke I labelled it "LA

Dear all, Recently, we run 2 models with heat sink attachment on top of this BGA(on top of this BGA, there is flip chip attached at the center of the BGA). Hence, the center of the BGA is higher than corner/side. We used conventional way to attach

What's the point of such a test? * If you are operating a board in an environment that keeps the board at a temperature that is close to causing delamination, why not design a board that can tolerate such an operating environment, rather than contin

50% of seeing it in a single pass. The only time we do this is if we have a board off the line that has delaminated. We'll run a sample of boards through bare to confirm that we have a bad batch. Even if we see no failures on the bare boards, we'l

Richard, With respect to the Resistivity of Solvent Extract (ROSE) test, the test solution is exceptionally aggressive. With the Zero-Ion for example, the test solution�s resistivity is 150 M-Ohms. Additionally, because test solution is made up of

You will have to be more specific about your boards and process to get any help. There are many different types of in circuit tests and functional tests throughout the manufacturing process. The nature of these tests depend on board function. Sinc
