Potting (gluing) refers to the process of filling devices containing electronic components and circuits with polyurethane potting adhesives, silicone potting adhesives, or epoxy potting adhesives, either by equipment or manual means. Under normal temperature or heating conditions, it solidifies into an excellent thermosetting polymer insulating material with outstanding performance, thereby achieving the purposes of bonding, sealing, potting, and coating protection.
The main functions of potting are:
1) to enhance the integrity of electronic components and improve their resistance to external impacts and vibrations;
2) to improve the insulation between internal components and wiring, which is beneficial for the miniaturization and lightweighting of devices;
3) to prevent direct exposure of components and wiring, thereby improving the device's waterproof, dustproof, and moisture-resistant performance;
4) to facilitate heat dissipation and heat conduction.
What should be considered when selecting potting materials?
1) Requirements for performance after pooping: use temperature, alternating cold and heat, internal stress of components, outdoor use or indoor use, stress status, whether flame retardant and thermal conductivity are required, color requirements, etc.;
2) potting process: manual or automatic, room temperature or heating, complete curing time, solidification time after mixing glue, etc.;
3) Cost: The proportion of potting materials is very different, we must look at the actual cost after potting, rather than simply look at the price of materials.
