Resin Hole Plugging PCB Board: Epoxy vs. Polyurethane Showdown.
If you're looking for a way to protect your printed circuit boards (PCBs) from the elements, you might be considering resin hole plugging. Two popular types of resin for this application are epoxy and polyurethane. In this article, we're going to compare the two and help you decide which is right for your project.
What is resin hole plugging?
Resin hole plugging is a process used to seal any holes in PCBs. These tiny holes are often created during the manufacturing process, to stop the internal circuits from shorting out. Sealing these holes with resin stops dust, debris, and moisture from getting inside the board and potentially damaging any electrical components.
Epoxy vs. Polyurethane.
Epoxy and polyurethane are both effective resins for plugging PCB holes. However, there are some differences between the two. Below, we've listed a few of the most significant differences to consider.
1. Strength and Durability.
Epoxy is known for being incredibly strong and long-lasting. Once it's fully cured, it can withstand significant pressure and impact without cracking or breaking. On the other hand, while polyurethane is also durable, it's not quite as strong as epoxy.
2. Flexibility.
Polyurethane is more flexible than epoxy, which makes it a better option if you need a little more give in your PCB. However, epoxy is a less flexible option. So, if you're dealing with a more robust PCB that doesn't need to bend or flex, it might be better to go with epoxy.
3. Chemical resistance.
Both epoxy and polyurethane are resistant to chemicals, like solvents and acids. Epoxy, however, is less prone to reacting to chemicals when compared to polyurethane. .
4. Cost.
Polyurethane is the less expensive option by a significant margin compared to epoxy.
So, which one is right for your project?
It depends on what you need from your PCB. If you need a long-lasting, high-strength solution, go with epoxy. If you need something that can flex a little more without breaking, polyurethane is the better option.
