What should be the reason for the appearance of tilting and opening welding when using the tactile switch? What led to it? Now let me give you a detailed introduction.

In each assembling process, we tested the stress of four workstations which may produce greater mechanical stress. The four work stations are: sub board work, hot melt welding station, shell assembly station and testing station. The stress sheet is attached to the position of the touch switch so as to obtain the larger stress of the switch position when assembled. The test found that the instantaneous stress was in the sub plate working site with a stress value of 810ue.
Referring to the IPC-9704A standard, the stress generated during the splitting process is in an acceptable range. However, there is still room to reduce the peak stress, so further hypothesis testing and verification tests need to be arranged.
