Although the design of aluminum based printed circuit boards (PCBs) is no different from that for a traditional FR-4 board, the similarities are limited to the imaging and wet-processing operations. To make the design cost-effective and manufacturable, an additional secondary mechanical operat...
If you are looking for small volume electronic products that must be highly reliable while operating at high frequencies and high insulation in environments with high pressure, high temperature, and high pressure, Metal Core PCBs (MCPCBs) may be a good choice. However, there is other alternati...

PTFE or polytetraflouroethylene, commercial name Teflon, has an inert molecular structure that makes it an excellent material for use as non-stick coating. PCB fabricators are increasingly using PTFE laminates compared to conventional FR4 materials, because of the unique properties of PTFE tha...
Introduction Although Light Emitting Diodes (LEDs) operate at very high efficiencies, they do produce heat as a byproduct and this has to be removed if the LED is to operate continuously. As the heat generation in a semi-conductor, such as an LED, happens in the PN ...

Introduction While designing multi-layer Printed Circuit Boards (PCB’s), one of the most basic elements that the engineer must include is the requirement for interconnected traces/planes on one layer to traces/planes on another. The most efficient technique of...
