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, orTMS), 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.
Reflow Soldering
profile:
(260°C
peak Temperature)
Recommended Soldering Conditions:
WAVe SOLDeRInG: 260°C maximum solder temperature for 5 seconds max.
** note: 100% matte tin terminal plating does not meet MIL-S-83504 for lead content.
