Why is this capacitor covered in glue : r/AskElectronics

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

6 FAQs about [Capacitor glue injection sealing principle]

What is a good adhesive for a capacitor?

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.

What is the purpose of gluing a capacitor to a PCB?

Getting 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.

Why are capacitors soldered through holes in PCB?

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.

Can you use hot glue on silicone caps?

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.

Can a conductive adhesive mount cause a short circuit?

With the conductive adhesive mount, short circuits can occur between electrodes if adhesive leaches out at the lower surface of the part during mounting. Figure 3 (1) and (2) show schematic diagrams of before and after mounting a part with a conductive adhesive mount.

What is a multilayer ceramic capacitor GCG series?

Our company has commoditized the multilayer ceramic capacitor GCG series for the above-mentioned markets. This series includes external electrodes consisting of Ag (silver) -Pd (palladium) and exhibits reliable adhesiveness with conductive adhesives.
