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.
Environmental Conditions The operating environment of the electronic device considerably influences the choice of potting material. Materials with specific resistances, such as silicone or epoxy, may be required for devices exposed to extreme temperatures, high humidity, or harsh chemicals.
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.
Applications for shallow potting compounds include: These are some of the products you'll find on Gluespec. Loctite AA 363 from Henkel is a one-part, liquid acrylic product that cures with UV light and has a transparent yellow color.
Improved Reliability: By reducing mechanical stress and vibration, potting enhances the reliability of electronic devices. Cost-Effective: Potting can be a cost-effective solution for protecting sensitive components compared to other methods like conformal coating or encapsulation.
Elastosil N288 from Wacker is a two-part, liquid silicone thta cures at room temperature and provides excellent primerless adhesion. AS1723 from CHT is a one-part, liquid silicone that uses a non-corrosive, neutral alkoxy cure. Teroson PU 8910 is a one-part liquid polyurethane adhesive that is free from solvents and PVC.
