Hi All, We encounter capacitor crack in the ICT, it contributes 2% of the failure. We are not sure whether these crack coming from the SMT. All these crack having the same pattern. Please refer to attached file. Anybody encounter the same thing befo

Your product is Class 3, correct? Otherwise, a clearly wetted connection is all you need.

In addition to robl's suggestions, I would look at the footprint on the board to make sure it meets the recommended dimensions. Abnormal layouts, particularly when pads extend under the component too far, can be problematic both by lifting the part

Hi All, Can someone please help, I have a number of tall surface mount components that according to IPC 610 (8.2.2.3) are a fail due to the end termination not wetting at least 0.5mm + solder height. The components are very well soldered but the sol

Hi Steve Thanks for coming back to me, you are correct IPC class 3 is required. We are getting great wetting onto the device but not as per IPC 3 with the wetting rising about 0.25mm. I am questioning whether it is actually possible with such a (re
