Compunetics has been operating in the embedded components market for more than 20 years. Initially driven by their parent company’s need for high layer-count, high-density embedded capacitance cards for their OEM product offerings, technology and processes were developed which are mature and reliable. Embedded technology is integrated into PCBs using conventional processing techniques; the capacitive layers are drop-in replacements in the existing PCB stack. However, special processing is required to properly transport the extremely thin cores associated with embedded capacitance layers (three to 25 microns thick).
Embedded capacitors rely on utilization of planar copper-clad, thin-core laminate (Figure 1). These laminates replace decoupling capacitors which are normally mounted next to an IC. The IC is routed directly to the capacitive layer using vias. The laminates are drop-in replacements that use the existing PCB stack-up. Various dielectrics and core thicknesses are available. For example, DuPont HK04 material utilizes a 1-mil copper-clad polyimide core which functions as an ideal capacitor (Figure 2).

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.

ICT technical director Bill Wilkie is well-known for choosing notable venues for Institute of Circuit Technology events, and his choice for this year’s Annual Symposium was the National Motor Museum, located in the village of Beaulieu in the heart of the New Forest, a national park in the county of Hampshire in Southern England. The region is known for its heathland, forest trails and native ponies.

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.
