The “Connector Basics” series from APEX Electrical Interconnection Consultants continues with a tutorial on how to specify and select a connector for a particular application. Generally speaking, electrical connectors are mechanical components that serve an electrical function. In addition to carrying electrical current at a specified voltage, connectors either enable interconnection of components during the Read More >>
Erosion in the Connector Industry Talent Base The connector industry has experienced significant erosion of its talent base in recent decades. Because this has occurred bit by bit over a long period of time, it’s not immediately apparent how significantly the industry has been changed by the loss of knowledge and experience these people represent.

Guidelines for Connector Specification During Product Design Connectors, unfortunately, may contribute to an unacceptably high product failure rate. One reason for this is that connectors are typically a low priority in the initial design phase of the system. This can lead to a design engineer getting boxed in with limited connector space and access if Read More >>
Our first in a series of articles about Evolving Levels of Interconnection As this is the first in a planned series of articles by APEX Electrical Interconnection Consultants LLC, we thought it would be best to begin with the “Levels of Interconnection” (LOI), which is about as fundamental as it gets. It must be remembered Read More >>

It must be remembered that at every interconnection point, at Read More >>
December 2013 – In 2014, the engineers and scientists of APEX Electrical Connector Consultants LLC will treat our readers to a series of articles on connector basics. We thought it would be fun to kick off the feature in this issue with a Q&A led by Bishop’s John MacWilliams.
September 2013 – Wear issues are best addressed in the design and manufacture of the connector system. Dr. Bob explains what causes wear in a connector and how the science behind the process works, then makes recommendations to help protect against connector wear in your next design.
October 9, 2012 – RFID solutions may provide a completely new approach to product lifecycle management and value creation in the cable industry. Alexander Schmoldt of Murata explains the latest innovations and how they can transform cabling infrastructure.
Heat-shrink tubing has been a staple in the electronics industry for more than 50 years. It is used for sealing, protecting, insulating, strain-relieving, and identifying wires and cables. Today, sustainable design and technological innovations have spurred the development of new heat-shrink products that meet special requirements and expand the range of possible applications.
Dr. Bob on Hertz Stress as a Connector Design Parameter I was looking for some information in my files a few weeks ago, when I came across a folder entitled “Hertz Stress.” My mind leapt back 20 years as I recalled discussions that the concept had raised at that time. Using Hertz stress as a Read More >>
To Fail or Not to Fail, That is the Question – Act II Dr. Bob reviewed the issue of failure criteria in the previous issue of ConnectorSupplier.com. He said that two different types of failures have to be addressed: catastrophic and systematic. He attached definition to both, noting that catastrophic failure results from quality issues Read More >>
More on Supplementary Testing – Now, what else do I want to do? In the prior articles of this series, the test groups described were for the determination or susceptibility of connectors to basic failure mechanisms: Vibration/Shock—Fretting Corrosion Discontinuity or Nanosecond Events Mechanical Integrity Humidity/Thermal Cycling—Fretting Corrosion Wet Oxidation Process Degradation of Plastic Housing Mixed Read More >>
