Abstract:
According to exemplary embodiments, a tapered surface interconnect is formed on a printed circuit board (PCB). A compliant pin of an electrical connector may be coupled to the tapered surface interconnect and soldered thereto. The depth of the surface interconnect may be shorter than a height or a thickness of the PCB. The surface interconnect may have a tapered side wall to allow for a better fit with a tapered compliant pin. The inclination of the side wall of the surface interconnect may be linear or concave. The intersection between the tapered sidewall and the bottom of the surface interconnect may be rounded to minimize pin insertion issues and may allow for easier solder flux evacuation from the surface interconnect during the soldering process. The compliant pin may be soldered into place upon being coupled to the tapered surface interconnect.
Abstract:
The invention concerns a module, in particular designed to be used in chip cards, consisting of a chip module including an integrated switching circuit and a transmission module comprising at least a transmitting element for data and/or energy transmission between the integrated switching circuit and an external appliance or vice-versa. The chip module and the transmission module each have contact elements used for their mutual electrical connection, the chip module (3) contact elements (11) and the transmission module (2) contact elements (7) being assembled by blocking the mutually corresponding contact elements (7, 11).
Abstract:
[Object] An electronic component on-substrate mounting structure capable of mounting an electronic component having a round external shape on a substrate in a predetermined attitude and keeping an allowance of a lead to a predetermined value is provided. [Means for Settlement] A lead 12 of an electronic component 11 is inserted into a lead hole 31 of a substrate 30, thereby mounting the electronic component 11 on the substrate 30. The lead 12 includes a base part 16 extending from an electronic component main body 13, a support part 17 bent from the base part 16, abutting an electronic-component mount surface 30A of the substrate 30 at a predetermined length, and supporting the electronic component main body 13, and an insertion part 18 bent from the support part 17 and inserted into a lead hole 31 of the substrate 30.
