Profiles are absolutely the first course of action to validate. A few additional questions would be: * Moisture can cause warping as well, verify the manufacturers recommended handling procedures were followed. * Where is the suspect BGA located

There is no standard for a strain gage measurement of allowable deflection of a board or a fixture. It's possible that your fixture is causing the BGA cracking that you see. What protion of the BGA is cracking? If it is the solder connection, sear

Manufacturing processes, handling and printed circuit assembly (PCA) test can put a lot of mechanical stresses on packages, causing failures. As grid array packages get larger, identifying how to set safe levels for these steps becomes more difficult. A new quantitative test methodology within IPC/JEDEC-9707, Spherical Bend Test Method for Characterization of Board Level Interconnects, lets users determine how much strain packages can take before reliability degradation.

LED lamp bead because of energy saving, low carbon environmental protection, no strobe, no radiation, high brightness, low heat advantages are gradually replacing the fluorescent lamp on the market, its application scope is expanding,although LED has many advantages, if the production or operation is not appropriate,there will be LED strip use fault phenomenon. LED lamp strip manufacturers also begin to pay more and more attention to the problem of production quality, then what equipment can be used for LED lamp strip backlight detection? Unicomp Technology here recommended AX8200L LED strip backlight detection equipment.
