| | I have a 2-up panel measuring about 8" x 8" with a score for depanel throuch the middle. I see warping after reflow of the panel (bending in/about score line). The board is not framed (i.e., supported) during SMT reflow other than on the conveyor

How is a squeegee considered damaged? Is just a bent blade sufficient to call it 'unfit for use'. How much bend, in a blade may be considered unfit? How much do dents on a blade affect squeegee perfomance? what is the effect of blunt blades on print

Hello, Does any one as a database regarding component assemble by hand on a PCB. More accuratelly how much time (per sec) does it take to bend leads on a component(res), time to insert the component by hand, time to solder by hand. Any time base dat

You should be looking for a better method of depaneling your boards. Listen. If you breaking components, it's not the component. It's you. Either you are: * Applying too much force. * Bending the board too much. * Locating the components too clos

Grant, Yes they do get broken by the operator or whom ever is loading or unloading the feeder stick pulling the tape through the feeder and the component pocket will snag the tip of the plow and bend it so that the tip ends up breaking off making

Inspect the cables specially in those area where cables have bendings with the motor motion. If they have something covering them or extra insulation try to remove it and inspect closely. If the machine runs and suddenly stops with this error and aft

Be careful when using compressed air, it will not only �blast it all into the air you breathe�, it can also damage the stencil by bending the delicate land mass areas of fine-pitch apertures. I recommend the article �SMT Stencil Cleaning: A Decision

during the soldering process on larger BGAs the corners can bend up or down due the large copper heatsink on top expanding quicker than the material the bga is made out of, in the worst cases this can lead to to the balls lifting out of the paste and

Samir, This growth doesn't look like a tin whisker which are needle like and very fragile (they don�t bend they break). I have seen similar growth in the past in an EMS defect analyses with connectors in stressed conditions. The growth seen was sim
