20190148099 · 2019-05-16 ·

An electronic assembly contains a circuit board having a current-conducting current path with two mutually spaced-apart current path ends that form an interruption point and a contact clip bridging the interruption point. The contact clip is manufactured without a preload, as a thermal fuse. The contact clip has a multiply bent, open clip loop and a contact limb making contact with both mutually spaced-apart current path ends using solder. The contact clip further has a fixing limb with a limb end seated in a circuit board opening. The limb end of the fixing limb has an oversize relative to a circuit board opening, and a deformation being imparted to the contact clip, with an internal preload being generated.

Conductive polymers within drilled holes of printed circuit boards

A triggering condition is applied to a conductive polymer positioned in a drilled hole in a printed circuit board. The applied triggering condition causes the polymer to vertically expand within the drilled hole such that the expanded polymer creates an electrically conductive path between contact pads located in different layers of the printed circuit board.

Methods of laser trace post processing and depaneling of assembled printed circuit boards

A method for processing a PCBa panel to individualize the PCBa's on the PCBa panel and depanel the PCBa panel in substantially one step is described. The PCBa panel initially comprises a number of PCBa's having components and traces common to a number of different product SKUs. During processing, the PCBa panel is loaded into a machine containing a first and second laser. The first laser severs extra traces on each PCBa to individualize the PCBa's for specific SKUs and the second laser cuts the links between each PCBa, thereby depaneling the PCBa panel.
