There has been a growing adoption of NiP thin film resistors as heater elements from a diverse group of users including those in the aerospace, defense, high-end computing and the volume consumer electronics market. This has included interest and use from those responsible for validation and reliability testing. A novel application has now grown from the validation and reliability testing perspective. Using embedded resistors as heaters to do high-temperature or burn-in testing eliminates the need for thermal chambers.
The idea of using embedded resistors as heaters in PCBs is not new. In the past embedded resistors as heaters have been used to raise the temperature of critical components on PCBs to optimum operating levels. A couple of examples include the semi-active laser (SAL) board in guided munitions and an X-ray spectrometer board in the ESA Mars Beagle II Lander. Another recent space application required the melting of plastic fasteners. The plastic fasteners were used to secure folded solar panels during launch then deploy when the unit was in orbit. An embedded heater solution was designed to conform to the physical space, power and reliability metrics specified and selected based on its performance.

After entering the North American marketplace just six months ago, printed circuit board provider Fineline-Global is making its mark. As the largest value-added PCB supplier in the world, Fineline prides itself on being any able to meet any challenge for any company in any part of the world. I recently had the chance to sit down with Eran Navick, the company’s North American CEO to catch up on how things are going.

The design process is arguably the most important part of the flex circuit procurement process. The decisions made in the design process will have a lasting impact, for better or worse, throughout the manufacturing cycle. In advance of providing important details about the actual construction of the flex circuit, it is of value to provide some sort of understanding of the expected use environment for the finished product.

For this first issue of Flex007 Magazine, we interviewed John Talbot, president and owner of Tramonto Circuits. Headquartered in metro Minneapolis, Minnesota, Tramonto manufactures flexible and rigid PCBs for a variety of industry segments. Editors Andy Shaughnessy, Patty Goldman and Stephen Las Marias asked John to discuss the challenges and opportunities in the world of flexible circuits, and some of the trends he’s seeing in this market.
