How To Protect PCBs from Harsh and Challenging Environments

In this months blog, I thought I would continue with my theme of five ‘Top Tips’ for circuit designers and manufacturers who seek to ensure that the in-service reliability and longevity of their electronic assemblies and products are fully addressed.

1First, think very carefully about the sort of environment your PCB is likely to encounter. It is easy to ‘over-engineer’ a product in order that it will survive the very worst of conditions, but ‘worst conditions’…

I have been working with polymers and resins for more than 20 years now and, modesty aside, have been involved in a number of significant developments ranging from structural composite resin and pre-preg systems for the aerospace and automotive industries, to my current activities with Electrolube and a strong team of chemists, formulating new resins for the protection of modern electrical and electronic assemblies.

Over this period, the electronics industry has witnessed an extraordinary rate of technological change - and we chemists…

To encapsulate or to coat: that is the question

Potting compounds and encapsulation resins are generally two-part systems, in which a resin is mixed with a hardener in a precise ratio to form a cross-linked polymer when cured. It’s also possible to add mineral substances (‘fillers’) to resins to improve their performance under certain operating conditions. Like conformal coatings, most resins will cure at room temperature, and while this can be a relatively slow process in the case of potting resins, cure time can be reduced by applying heat.

An important thing to be aware of when…

Last month, I departed from my usual format - essentially to provide as much information as possible on the subject of resins, their formulations, chemistries, special properties and so forth, to concentrate more on how they are used to solve real world problems. As I mentioned last month, there is a growing interest in LED lighting, which offers a more efficient and longer-life alternative to halogen, incandescent and fluorescent lighting systems for both interior and exterior applications,…

Casting A Spotlight On LED Resin Applications

Over the last few blogs, I’ve given readers pointers on virtually every aspect of potting and encapsulation resins, ranging from their formulations and special properties to their applications, benefits and limitations. It’s probably high time, therefore, to take a step back from the do’s and don’ts and focus instead on how these resins are bringing very real benefits to practical electronic and electrical engineering applications; and a good starting point is to look at the special requirements of an industry…
