This KYOCERA AVX whitepaper by Ashok Dhulgande and John McCarry discusses key design considerations for electrical spring contacts and board connections and provides an overview of KYOCERA AVX’s card edge connectors for automotive applications. Board-to-board Interconnect It is often necessary to electrically connect two printed circuit boards (PCBs) directly to one another without using an Read the original post Card Edge Connectors For Automotive...

The number of individual engineering polymer products has exploded in the past years due to specialized requirements on the polymer being addressed by a variety of additives. Additives and the function they provide include: Flame Retardants: Most connector housings are required to meet flammability requirements, burning rates and combustion products, defined by various product safety Read the original post Polymer Families on inter-connection components...

There are two processes used to convert polymer resin pellets to a connector housing, compression/transfer molding and injection molding. Before discussing those processes, however, another method of polymerizing the starting resin must be mentioned for completeness, condensation polymerization. Recall that addition polymerization occurs by the addition of individual mers to existing polymer chains under the Read the original post Polymer Processing on inter-connection components...

The majority of connector housings are manufactured from thermoplastic polymers due to their combination of electrical and mechanical properties and the manufacturing efficiencies of injection molding. This section will provide an overview of polymer materials and properties and a brief introduction to injection molding. The word “polymer” describes the structure of polymers in that its Read the original post Polymer Materials on inter-connection components...

This Würth Elektronik webinar provides expert knowledge on ZIF contacts selection guide and design of the interface at RIGID.flex. Flex and RIGID.flex PCBs are often designed with a ZIF interface (ZIF = Zero Insertion Force) and have a so-called ZIF contact for connecting a module via a detachable plug connection. There are different possibilities in Read the original post ZIF Contacts Selection Guide; WE...
