Development BackgroundAs mobile devices such as smartphones incorporate increasingly higher functionality and slimmer designs, it is necessary to reduce the size of components embedded in these devices without compromising reliability. Connector contacts are usually formed using a pressing process, but pressing technology has several serious drawbacks. For instance, with pressing technology it is difficult to make the width of formed products smaller than the thickness of the original sheet to be pressed, and there are limitations on how far the bending radius of metal can be reduced. These drawbacks make it difficult to satisfy customer demand for greater miniaturization and higher contact reliability.

OMRON has found a way around these problems by specially developing a new electroforming technology based on further advancement of the company's microfabrication and materials technologies. This advancement has led to the development of a battery connector with a 2mm pitch and a 2.6mm depth, using subminiature contacts that are impossible to form with conventional press technology.


The industry's smallest pitch and depthThe XD2B's significantly reduced PCB footprint contributes to further miniaturization of devices and larger battery sizes.

High contact reliabilityThe XD2B's contact is significantly stronger than conventional pressed contacts. Its spring-contact configuration fits tightly to the battery contact pad improving contact force, and providing greater resistance against momentary power outages caused by drop impacts.

Future PlansOMRON plans to expand the range of applications of its electroforming technology to include a variety of other high-precision micromachined components such as inspection sockets for semiconductors, etc.

OMRON's Electroforming TechnologyElectroforming is a metal forming process that forms ultra-thin metal components through an electroplating process. The components are produced by developing a layer of metal onto a base form (master). Once the plated layer has been built up to the desired thickness, this newly formed part is stripped off the master substrate. Electroforming enables high-precision production of extremely small, thin, and fine parts. OMRON also produces dies using microfabrication technology to meet more exacting needs for shapes and sizes, thus enabling transfer of a pattern with submicron-scale (0.0001mm) accuracy.
