What is PCB Insulation? PCB insulation refers to the process of applying a non-conductive material to specific areas of a printed circuit board to prevent electrical current from flowing between adjacent conductors, such as traces, pads, and vias. This insulating layer acts as a barrier, ensuring that the electrical signals travel only through the intended paths, thus preventing short circuits and signal interference. The Importance of PCB Insulation PCB insulation plays a vital role in Read more…

What is Conformal Coating? Conformal coating is a protective layer applied to printed circuit boards (PCBs) to shield them from environmental factors such as moisture, dust, chemicals, and extreme temperatures. This coating is a thin polymeric film that “conforms” to the contours of the PCB, including the components and solder joints. Conformal coating is essential for ensuring the reliability and longevity of electronic devices, particularly those exposed to harsh conditions. Types of Conformal Coating There Read more…
