Terminal Strength: Per specification Thermal Aging: 1,000 hours at 85°C; no failures. Environmental Ratings Meets all requirements of MIL- S-83504. Where Grayhill performance is superior, the MIL spec is listed in parentheses. Moisture Resistance: Per specification, Method 106. Soldering Information Series 90 MIDIP® and Series 76 recessed rocker (76RSB style) sealed switches have been tested to EIA Standard RS-448-2. Similar performance can be expected from other sealed Series 76 and 78 DIP switches. Solderability: Per MIL-STD-202, Method 208 Resistance to Soldering Heat: 76RSB: Passes EIA Standard using two, four, and six second soldering time. 90: Per MIL-S-83504, six second test. Fluxing: Per EIA RS-448-2 with flux touching switch body. Cleaning: 76, 78 and 90 Series tape sealed products: Passes immersion test using water/ detergent. Acceptable solutions include 1-1-1 trichlorethane, freon, (TF, TE, or TMS), isopropyl alcohol, detergent (140°F maximum). Terpene acceptable for Series 90 only. Solutions which are not recommended include acetone, methylene chloride, freon TMC. Materials and Finishes Shorting Member (Ball): Brass, gold-plated 10 microinches minimum over nickel barrier. Base Contacts: Copper alloy, gold-plated over nickel barrier. Terminals: Copper alloy, matte-tin plated over nickel barrier. Non-Conductive Parts: Thermoplastic (UL94V-O) Potting Material: Epoxy, 76,78 only. Protective Cover: 76,78, only-Polycarbonate. Tape and Reel Packaging Tape Seal: 76, 78: Polyester film 90: Polyimide film Tape Seal Integrity: Passes gross leak test using 125°C flourinert for 20 seconds minimum.
