In today’s post, we’ll help you narrow down your choices when it comes to choosing the right electrical potting compound. Below are the factors you need to consider before choosing the right product for different electrical potting applications.
Insulation Property
Since electrical potting involves working around different electronic parts, the right electrical potting compound should have excellent insulation property. Furthermore, circuit boards run in applications of different voltage levels —low, medium or high thus insulation should be first considered.
Adhesive Strength
Typically, electrical potting is meant to hold different electronic parts permanently. So, look for the potting compound that offers the level of adhesive strength you need. If not, then look for a suitable adhesive accelerator to speed up the process.
Moisture and Chemical Resistance
Electronic parts in printed circuit boards are mostly made of metals that are prone to corrosion. For this reason, the right potting compound should protect these electronic parts from moisture, rust and chemical damage.
Thermal Stability
A potting compound that offers thermal stability gives an added protection when potting printed circuit boards. Specifically, a thermally stable potting compound at elevated temperatures is ideal for potting and encapsulating sensitive electronic parts like thermistors. Otherwise, these sensitive electronic parts could be damaged due to overheating.
The above factors are just some of the important things you need to consider as different electronic applications would require specific potting compounds. So, it is best to look for products that are specifically suited to your needs.
