Soldering Information
*For the most current soldering & cleaning processing
guidelines, reference Grayhill Dip Switch Processing
Information, Bulletin 1234
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.
Reference MIL-STD-202, Method 112.
