Bow and twist of printed circuit boards (PCB) tends to be the highest amount of falsely identified non conformances and the least understood. Perfectly flat rigid circuit boards as a norm, is a misconception held by many incoming inspectors. Understanding the reasons and causes for bow and twist can help resolve the issue at the board design stage.

When building a Lithium-Ion Battery pack there will always be some sort of protection circuitry necessary that will safely separate the cells from the external connections. The protection may be as simple as a pair of Charge and Discharge Field Effect Transistors (FET’s) with voltage and current detectors, or may be as complicated as adding firmware controlled fuel gauging and secondary protection.

As many of you know, Epec Engineered Technologies was one of the founding members of the Institute of Printed Circuits (IPC) and is one of the oldest printed circuit board companies in the U.S. and have been making them since 1952. While visiting a customer I was asked, “Has the introduction of the new products custom battery packs and energy efficient EC fans taken your focus and attention off of PCBs?” While I assured the customer that we are fully dedicated to printed circuit boards and outlined all of the reasons why. It occurred to me that as a company, we haven’t done the best job of demonstrating that to our customers.
