Servometer metal bellows utilized for flexible connectors may be cost-effective repeatable solution. These are manufactured by first machining a piece of aluminum into a mandrel, plated with precision layers of metal to the desired thickness. Each end of the plated mandrel is scored through the plating to expose the aluminum to define the end trim dimensions and finally, the aluminum is chemically removed, leaving behind the precision thin shell of plated material which becomes the finished bellows.
For electrical systems, these springs are ideal for electrical interface to connect devices that are not permanently installed. Servometer electrical contact follows the same electrodeposition process for its construction as for an electrodeposited bellows. To increase conductivity, a layer of gold is plated over the bellows to ASTM B488. Signal can travel along the walls of the bellows rather than traveling the path of a spring, resulting in lower DC resistance, minimal self-inductance, and minimal insertion loss.
Bellows electrical contacts great solution for testing electrical circuits, whether from incoming inspection to final test. The bellows assembly was designed as less than one millimeter diameter and one millimeter in length with a coned front end to complement the external geometry of the components being tested and can compensate for offsets and vibration due to its flexibility. They can also withstand the various heating processes within the chamber as well as an ultra- high vacuum.
