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
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 Seal:
76, 78:
Polyester film
90:
Polyimide film
Tape Seal Integrity: Passes gross leak test
using 125°C flourinert for 20 seconds minimum.
Reference MIL-STD-202, Method 112.
