Terminal Pins and Assemblies

Vero Technologies offers a tremendously diverse range of Terminal Assemblies and Pins, but why the need for so many variants? All of the pins and assemblies share something in common; they fulfil both a mechanical and electrical function. However it is the application; the style of the connection and the base material that the pin will be used in, that compounds the diversity of parts – solutions are available not only for simple copper clad prototyping boards but also for single, double-sided and multilayer Plated Through Hole PCBs.

Terminal Assemblies

One of the most commonly used devices is the Terminal Assembly – installed in a board it provides an easy means of making a temporary connection; attaching a scope, measurement probe or test clip. The assembly has a spring leg design that is inserted into either a Plated Through Hole (PTH) or a single sided board and soldered in place – the compliant section ensures that the assembly is self-supporting during the soldering process. The terminal assemblies are available in a range of eight colours (Black, White, Red, Yellow, Green, Blue, Brown and Pink), making the identification and connection of a number of test leads much simpler, and with various size options, catering for two hole sizes and two thicknesses of PCB. The sintered glass beads can withstand 475^oC, so are unaffected by soldering. The terminal is formed from Phosphor Bronze wire with an electroplated bright Tin finish.

Header & Socket

Other styles of pins are the header and socket type – here the pin will receive either the leg of a device plugged into a beryllium copper insert in the head of the socket, or provide a slot for a wire or device lead to be soldered into. These pins are again available for different hole sizes and are typically soldered into the prototyping board, with a wire-wrap tail protruding on the reverse side for connection purposes. The pins for soldering discrete components are fairly simple, with a slot in the top of the pin and a wire wrap tail that protrudes on the other side of the board. However they are available for both single sided (non PTH) and double sided boards. Various tail lengths are also available.

Solder Terminal Pins

The third class of pins are solder terminal pins – outwardly one of the simpler types, however there remains a diversity that leads to six different styles, giving connection options to one or both sides of the board. All of the solder pins are manufactured from brass material with a Tin finish (over a copper striking flash.)

Solder terminal pins refer to the means of making a connection but are not necessarily soldered into the board, indeed Vero Technologies offer a wide range of press-fit alternatives.

Surface Mount Technology

The terminal pins and assemblies range are now complemented by SMT test points, suitable for either manual assembly or use with auto-placement machines. Available in a selection of three industry standard sizes (0603, 0805 and 1206) all fabricated in a Copper alloy with an electroplated Tin finish. There is also a ‘ball and socket’ surface mount variant, which allows cable attachment with a simple push click-fit header.
