What Makes Polyurethane Potting Compound For Electronics Thick
Potting compounds are flooding the electronic assembly market, and sometimes this can make it hard for newbies to make the right choice. In case you are not aware, Polyurethane potting compounds are perfect for electronics. They are considered that way due to their incredible features.
What features do you need to know about polyurethane potting compound for electronics? The answer to that question will be explained in the body of this post. This article will take time to highlight the best-selling attributes of this particular potting compound. This will certainly increase your confidence to invest more in this business. Here are some features that make this potting compound thick.
Should Ensure Protection
This is the first assignment of every potting compound. There is need to offer protection to the PCB, so its operations are not interrupted by external conditions. Therefore, they must be rigid enough to prevent any intrusion from the outside. All forms of interruption must be stopped.
A PCB’s operations ought to be isolated from external activities of all kinds. Those activities only negate the efficiency of the circuit. Therefore, polyurethane potting compound for electronics have become increasingly popular amongst electronic assemblers because of its ability to offer maximum protection. With adequate protection from the external environment, the PCB is bound to experience a healthy service life.
Water and Chemical Protection
Protection against water and chemicals of diverse kinds is also a necessity for printed circuit boards or anything that houses electronic components. Water can easily wreak havoc on a PCB if not checked. The same thing can happen when chemicals come close to them. Whether they are corrosive or mild, chemicals need to be kept as far as possible from electronic circuit boards.
Luckily, you can get all the protection you desire from polyurethane potting compound for electronics. They are designed with waterproofing features that make it almost impossible for water and chemicals to make any incursion into the PCB. The potting compounds are also inert to chemicals no matter how long they are exposed to them.
One thing that characterizes polyurethane potting compound for electronics is their high thermal conductivity. Their ability to remain in shape within a wide temperature range is key to PCB’s performance.
If a potting compound for electronics remains in shape in the face of heat, the board will continue to work as if nothing has changed. However, if the seals break during the temperature changes, that could spell doom for components on the board.
Some potting compounds can fail in the face of temperature changes. Before settling for any potting compound, ensure it can withstand high temperature changes and other environmental factors.
That said, it should be noted that a polyurethane potting compound for electronics cannot be used when temperatures exceed certain levels. As a matter of fact, if the temperature rises beyond 125C, using a polyurethane potting compound will prove to be a bad choice for such scenarios.
Excellent Electrical Properties
A polyurethane compound for electronics is equally expected to have good electrical properties. That is because most times, the potting compound needs to be a part of the board.
A polyurethane potting compound for electronics can be used to fix broken sections of a PCB. That is why they are used for sealing. So, even if a board has holes, or is broken, these compounds can be used to fix them.
With potting compounds having good electrical properties, the board can look new again. Not only that, a polyurethane potting compound for electronics needs to possess good physical properties and mechanical properties too.
Assemblers in the electronics assembly industry prefer solvent-free polyurethane potting compound for electronics. You want to do everything possible to avoid using potting compounds that are not 100%.
The completely solid potting compounds have proven to be the best time and again. They can seal the gaps, holes, and also retain all the properties necessary to make them function as expected. In other words, the solution is initially viscous, with the ability to metamorphose into something harder that can offer PCBs the best protection.
It is one thing to be a good potting compound, but another thing to possess quality underfill qualities. Finding a potting compound that can fill cavities within an electronic assembly is one of the things you should be looking for in this regard.
As far as experts are concerned, that is the distinguishing factor for knowing the best polyurethane potting compound for electronics. If potting compounds cannot fill holes and cavities on PCBs, then you don’t have need for such. Their ability to serve as reliable underfills for cavities should be the basic criteria for choosing a potting compound for electronics.
One-Part or Two-Part Solutions
This will probably be the last decision you have to make when choosing a polyurethane potting compound for electronics. Many potting compounds exist in single part and dual part formulations. Both part systems have their advantages and disadvantages. In other words, you can use both to achieve your goals.
But finally, everything boils down to your level of experience. The most experienced assemblers can manage two-part systems. They can use them for high-level potting assignments. Inexperienced assemblers, on the other hand, are most convenient with single part systems. That is because they don’t possess the skills and experience to mix the solutions accordingly. So, if you are new to the assembly industry, you may want to stick with single part systems because of their user-friendliness and simplicity.
A polyurethane potting compound for electronics is making huge waves in the electronic assembly industry because of its unique and powerful features. In this article, we have seen what makes this potting compound thick. The features above show that it ticks almost all the boxes. From having good properties to possessing electrically conductive abilities, polyurethane compounds make a good choice for potting electronic components. Investing on a polyurethane potting compound for electronics does not sound like a bad idea for now.
