Features of Precious Metal Stripe and Spot Plated Strip

1.

Integrated production from manufacturing of raw materials to surface treatment offers thefollowing:● Proposal for optimized combination of copper alloy strip and precious metal plating.
---e.g. gold or palladium selective plating on a copper alloy strip or silver stripe plated strip.
● Comprehensive quality assurance from raw materials to final plated products.
● Supply of plated strip with superior bendability best suited for customers’stamping process.
● Stamping of pilot hole for spot plating is available in-house enabling significant reduction of lead time.

2.

 ince special jigs for partial plating are used eliminating expensive tape masks, selectiveS
plating with reduced cost and high positional accuracy is offered.

3.

 urukawa Electric’Fs outstanding plating technology enables to offer plated products having
excellent distribution in plating thickness.

4.

Due to high-performance plating lines, the gold and tin plating + reflow can be carried out
in a single process, excluding certain special products.

5.

The quality of plated products is supported by high-performance equipment and sophisticatedanalysis technology of R&D division of Furukawa Electric.

Application to Micro Motor Contacts
Our company is manufacturing plated products for micro motor brush and commutator applications. Previously, Cu alloystrips which were clad with precious metal foil like Au, Pt, Pd, Ag etc. had been used for these applications. But the large
amount of precious metals used for them and their complicated manufacturing process made these materials themselves
so expensive.
Then our company developed Pd-plating for brush application and Au- and Ag-plating for commutator application to reduce
the production cost drastically, which were received by our customers favorably.
These plating have also a merit of increasing the life of not only micro motor but also movable contact like brush forencoders.
