Materials Soldering and cleaning process *For the most current soldering & cleaning processing guidelines, reference Grayhill Dip Switch Processing Information, Bulletin 1234 cleaning tape sealed products: Passes immersion test using water/ detergent. Acceptable solutions include 1-11 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 . Pressure wash cleaning processes are not recommended for tape seal switches. Wave Soldering: Recommended solder temperature: 500°F (260C) max 5 seconds. Contact Ball: Brass with gold plating over nickel Terminals: Brass with gold plating over nickel Nonconductive Parts: Plastic UL94V-0 Potting Material: Epoxy Shorting Member (Ball): Brass, gold-plated over nickel barrier. Protective Cover: Polycarbonate. Tape Seal: Polyester film Tape Seal Integrity: Passes gross leak test using 125°C flourinert for 20 seconds minimum. Reference MIL-STD-202, Method 112. Hand Soldering: Use a soldering iron of 30 Watts or less, controlled at 608°F (320° C) approximately 2 seconds while applying solder. cleaning: Tape sealed versions withstand cleaning processes.
