AI Customer ServiceGetting differential diagnoses The purpose of the glue is to anchor the capacitor to the PCB so that it does not break off with vibration/drops. It looks like the application is not ideal in that case since there is very much glue on the capacitor and little contact between the glue and the PCB.
The adhesive is needed to prevent the capacitor vibrating (the leads acting like a spring) and moving around when device is subject to external forces. I’m looking for something like DOW CORNING 744 WHITE Adhesive, RTV Silicone or WACKER Silicone Adhesive Sealants (WACKER Silicone Adhesive Sealants - Intertronics) Take a look at these options.
Ya, I tried hot glue before I posted. As soon as the caps (or the board in general) warms up the least little bit, the hot glue releases. Be aware that not all silicone sealants are compatible with electronics. If I remember correctly, the ones with a strong acetic acid smell are a no-no, because it will cause corrosion.
Hi Michael, I think we misunderstood each other. The capacitors are leaded components that will be soldered through holes in PCB. The adhesive is needed to prevent the capacitor vibrating (the leads acting like a spring) and moving around when device is subject to external forces.
To keep the hellfire at bay. Capacitor is a relatively large mass to be anchored by just the leads and solder pads. In testing, probably something like life testing where it is operated until it no longer works. They count the number of cycles till failure and the reasons for failure.
There are also agreed specs between the engineer and the customer. It could be for this case, operator needs to apply the glue to the top and it is acceptable as long as it doesn't cover the board markings or it doesn't fully cover the component itself or others.
