PRESS-FIT TECHNOLOGY AS A CONNECTIVITY SOLUTION FOR THE HARSHEST ENVIRONMENTS

vibrations in the harshest environments. As a result, press-fit connections have been used successfully for more than 50 years, primarily in high-performance and safety-related applications such as automatic braking systems, rugged construction equipment, and power-tool applications. WHAT IS PRESS-FIT TECHNOLOGY? Press-fit technology is a solder-free option for making electrical-
Wherever high-stress environmental conditions such as temperature fluctuations, shock, vibration, moisture, dust, and dirt prevail, press- fit technology has proven itself to be a reliable partner. Press-fit technology creates a permanent mechanical and electrically conductive connection between the PCB and connectors. It can be used to create a simultaneous electrical and mechanical connection in just one process step. What’s more, press-fit contacts offer significantly greater power transfer than solder contacts
mechanical connections. The pins of a press- fit connector are first positioned into their intended location on the plated through-holes of a PCB, where pressure is then applied to the contact. The contact is pressed into the PCB hole using a defined,
thanks to their lower contact resistance of under 1 mW. Press-fit connections can be used at temperatures ranging from -40 °C to +150 °C and can readily withstand
Press-fit contacting can come in a variety of sizes and forms depending on the needs of a given application.
