Why Tin-Silver Coatings?Why Tin-Silver Coatings?1.) An upgrade from Pure Tin Coatings.2.)A replacement coating for Pure Silver

Plated female terminals mated to Pure Silver headers.

3.)A replacement coating for both male and female Pure Silver Plated Terminals.

4.) A Gold alternative. Where it makes sense. Ie: Under-the-Hood Applications

Why the Tin-Silver Push?Why the Tin-Silver Push? Throughout the vehicle, there are many terminal designs

with as many platings. Each use of these platings are because of A.)Cost and B.)

Temperature Class requirement. Improvement needed in insertion forces. A harder coating than Pure Tin. The 95-5 Sn-Ag coatings have been tested to all US Car

Class environments 1 thru 4 with success. Low normal force terminals from 1.5 to 8 Newtons. One pair of coating types A.) Silver B.) Tin-Silver

throughout the vehicle can expedite engineering design.

Mating Forces TestMating Forces Test Ralph and Rich, I was asked to summarize the insertion results we got from the various plating types we use on our Apex 1.2mm

female terminals (modified from our 1.5mm female terminal tooling). These terminals are used in our 3 way cam, crank, and coil-on-plug connectors released for Daimler Chrysler use.

  All values shown are in Newtons. Also, the results shown are from "first insertion" readings.   Please contact me if you have any questions.     Tin Plated: (mated to a Tin plated device blade) AVG - 10.66 MAX - 12.15 MIN - 9.15   Tin/Silver (95/5) Plated: (mated to a Silver plated device blade) AVG - 5.81 MAX - 6.25 MIN - 5.05   Gold Plated: (mated to a gold plated device blade) AVG - 3.66 MAX- 4.30 MIN - 3.15    Regards, Jeff Burnside FCI Automotive (248) 592-2831 Courtesy of FCI

Testing already performedTesting already performed F.C.I.’s 3-Way 1.2mm Cam, Crank & Coil

Sensor. 3.5 Newtons of Normal Force.Tested to US Car-2 Class 4. Sn-Ag Passed. **In Production.

Tyco’s Junior Power Timer.Tested to Temperature rise of 160 C. 95-5 Sn-Ag outperformed Thermic Tin and Europe’s version of Tin Silver. 98-2 Sn-Ag. The Eutectic of 2%Ag is too low. The melting point would be around 218 C. Below Pure Tin which is 232 C.

Delphi HVT 1.2 mm Program. Tested at Class 3 US Car-2. Sn-Ag passed and is spec’d out for production.

F.C.I.’s 2.8mm Terminal System Engineering Evaluation (EE) Level. 95-5 Tin-Silver passed all phases of testing.

US Car-20 TestUS Car-20 Test **An OEM tested their 150 series terminal family with a

Pure Tin male and Pure Tin female against the Sn-Ag male and Sn-Ag female version. *3.5 Newtons of Normal Force.

Tested to US Car-20 Class 3 125 C until failure. The results: 95-5 Tin-Silver passed and Pure Tin failed. This test showed that Sn-Ag is an upgrade. ** Lets say for example: Emission Control Terminals. The

warranties increase from 5 years to 15 years or 150,000 miles. Would this test put you in the comfort level if most of the terminals were 3 to 5 Newtons in normal force with the potential of Class 3 to Class 4 environments?

I propose that Sn-Ag does.

The fact that you can mate Tin-Silver female terminals to Pure silver headers without effecting performance.

In many cases, Tin-Silver females to Tin-Silver males. More of a cost savings.

In Gold applications, the worry of tin being mated to gold platings during assembly. No More!

One Stop shopping without effecting your existing supplier base.

Formability– Cast structure on hot-dip coatings, can go

through severe deformation with no cracking– Due to porous structure and stresses inherent in

electroplate, cracks can develop at sheared edges
