It may be obvious that any component added to a circuit path makes a contribution to the overall resistance of that path. This is certainly true of a set of mating connectors having a separable interface. However, the elements making up that contribution may not be so obvious. Each of the mating connectors includes three different regions that contribute to resistance. The portion of each connector that physically touches the other is the region of Interface Resistance.

Navigating the Connector Design Review Process
There are usually several Design Reviews conducted throughout the New Product Development cycle for electrical connectors. These reviews occur when the product is ready to pass from one of the several development phases to another. The primary purpose of a design review is to evaluate the ability of the outcome of design and development activities to meet requirements. The Design Review also provides a forum for all those involved in some aspect of the new product, to voice his or her opinions, concerns and approvals. This paper describes some of the topics required for the development and release of a typical new connector, such as one having stamped and formed contacts assembled into a polymeric housing. .

Patent Litigation Concerns and Considerations
If you are feeling secure because an exclusive design or end product contains various unique and patented components, you may want to think again Patent infringement litigation is on the rise. Companies are increasingly willing to enforce their patents, as noted by the following news clips:
“The number of new patent complaints increased by nearly 15 percent in 2015 over the year before, and intellectual property attorneys say they are being pushed to take on more work as law firms stretch their resources to adapt to the influx of litigation”.
“The record number of patent suits filed in (one Federal District) has created such an intense workload that it is putting a squeeze on the judicial system, as the number of patent suits filed there in 2015 shot up 77 percent over 2014”.

CCSI: Connector Crime Scene Investigation
Failure analysis investigation requires at least two ingredients: experts and technical means. This article briefly touches on the current expert situation in the US, particularly the effects of globalization. It also describes some of the technical methods used in failure investigation, starting with simple inspection, often aided by an optical microscope, and progressing to more advanced techniques, such as scanning electron microscopy (SEM) and X-ray radiography. In case of SEM it describes three main modes of this technology – secondary electron imaging (the most common), back-scatter electron imaging, and energy dispersive X-ray analysis. For radiography, it starts with regular high-magnification radiography that allows internal investigation of increasingly smaller parts, and proceeds to a full computer-aided tomography on a small and down to microscopic scale (micro-CT).

Managing Connector Design Changes
There are many possible motivations for considering and implementing changes to the design of a connector. Typically these would include:
•Enhance performance when requested by a specific customer or the general marketplace. (Competitive performance)
•Solve an unexpected problem with the connector design that was found after release of the connector to the marketplace.
•Reduce the connector manufacturing cost (Price competition)
•Materials used to make the connector are being discontinued by the supplier and must be replaced by an alternate material.
