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:
76RSB, 90: 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
10 microinches minimum over nickel barrier.
Terminals:
Copper alloy, solder-plated over nickel
barrier.
Non-Conductive Parts:
Thermoplastic (UL94V-O)
Potting Material:
Epoxy, 76,78 only.
Protective Cover:
76,78, only-Polycarbonate.
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.
Tape and Reel Packaging
Tape Seal:
76, 78:
Polyester film
90:
Polyimide film or foil
Tape Seal Integrity:
Passes gross leak test using
125°C flourinert for 20 seconds minimum.
Reference MIL-STD-202, Method 112.
