Traditionally used in aerospace Conformal coating protects electronics against damage from moisture and oxidation, by applying a thin breathable layer to circuit boards. Explore our guide to learn all about how this helpful technique is used for protecting wearable tech to industrial robots. Understanding the Basics of Conformal Coating At its most basic level, a conformal coating is simply a very thin layer of polymers. These coatings get their name from their ability to conform to the shape of whatever they’re protecting . The typical conformal coat is anywhere from 25 to 250 micrometers in width.  It repels water and other damaging materials, yet the unique polymers in conformal coats […]

A cold solder joint is a defect caused by improper melting of solder to bond PCB electronic components. This defect can impact the functionality of a PCB assembly, and so must be carefully avoided. Solder Joints on Circuit Board Introduction Soldering involves bonding two metals together using a solder alloy. Metal in the solder bonds with metal on the printed circuit board (PCB) or component. During this process, the solder melts into fluid molten to adhere properly to the component for an excellent solder joint. When the solder does not melt sufficiently, it creates a series of reactions that results in solder joint failure. This defect is known as Cold […]
