What is potting a circuit board?
What is potting a circuit board?
PCB potting is a method used to protect circuit boards (referred to in these contexts as the substrate) by filling the substrate's enclosure with a liquid material called a potting compound or encapsulation resin. ... Potting provides excellent resistance to heat, chemicals, impacts and other common environmental hazards.Sep 11, 2020
What epoxy is used for electronics?
An electronic grade epoxy resin approved for potting, encapsulating, casting, impregnating, & masking intricate componetry. Epoxyseal 9000 is an easy 2:1 mix ratio and cures rigid, with a brilliant, “blush free”, high gloss finish.
What is potting a connector?
Backpotting (or back-potting) is widely used in the connector industry to refer to the use of a potting compound on the rear of a connector (normally a cable connector). Potting is the filling of an area using an epoxy resin or similar liquid compound, which then hardens to a solid in-fill or barrier.Feb 21, 2019
Why is potting compound used?
In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for high voltage assemblies by excluding gaseous phenomena such as corona discharge, for resistance to shock and vibration, and for the exclusion of water, moisture, or corrosive agents.
Can you put electronics in epoxy resin?
Epoxy Resin Chemistry

Can you put electronics in epoxy?
Luckily, there are epoxies that meet all of these criteria. After some research, I found several epoxies specifically made for "potting" (encasing) electronics. ... I strongly recommend running some small scale tests like this before casting anything in epoxy.May 23, 2017
Can you pour epoxy resin over LED lights?
First, epoxy produces heat during the curing process and may damage the LED light strips. Second, it is impossible to replace the LED light strip.Nov 16, 2021
How do you dissolve PCB resin?
Heat the epoxy residue with a soldering iron set to 500-600°F. The epoxy will soften and lose adhesion, and can then be easily scrapped off. Again, this removal method can be used on metal, glass or any surface that will not be adversely affected by high temperatures, not PCB material.
How do you remove a potting PCB?
Potting material looks like a thin layer of putty on the PC board. It is always hard and varies in color. Allow the blowtorch flame to remain on the potting compound for approximately 10 seconds. 5 Set the blowtorch down and use a knife to scrape away the top layer of potting material.Mar 3, 2014
