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 aRead 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 issuesRead 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 MixedRead More
