6.1. Resistance to Flammability- When switches are tested as specified in IEC
Standard 69522, there shall be less than 3 seconds of continuous burning after removal
of burner, and falling burning drops or parts shall not ignite the cheesecloth
underneath. The following test conditions apply:
7.1. Solderability Testing. - Ten switches were tested to meet the requirements of
MIL-202, Method 208, condition#1 that specifies exposure to 16 hours of steam aging.
Following the steam aging, the switches were solder dipped and inspected per the
requirement that 95% of the soldered area on the terminals shall be free of pinholes
and voids.
8.1. Thermal Aging. - Twenty five switches were tested as specified in MIL-202,
Method 108A using condition “D” (1000 hours at 125 C.). The specification requires
that the switches shall be mechanically and electrically operative after the testing with
no greater than a 50% change in contact resistance over the initial readings.
8.2. Contact Resistance. - Contact resistance readings were taken at five hundred and
one thousand hours during the testing.
9.1. Resistance to IR Reflow Processing. -An additional hot air reflow test was
conducted to determine the ability of the switches built using the new material to
withstand temperature extremes by using a reflow profile at a higher temperature for
longer duration. The reflow profile used had peak temperatures above 270 C for a
duration of approximately 43 seconds. This profile is above the Grayhill
recommended temperature for processing the 90 series product but is intended to
demonstrate a safety factor above the typical lead-free reflow processing temperatures.
Five switches were processed for three cycles through the reflow profile described
above and tested afterward for contact resistance and mechanical operation. Although
it was noted that the plastic switch materials showed notable discoloration, the
switches performed electrically and mechanically as specified with no apparent
defects.
A. Test bottom of switch per position.
B. Use 30 seconds of flame exposure.
Five switches were tested to the specification as described in 6.1.and all of the
switches passed the specification.
All ten switches met the requirements as specified above.
All twenty-five switches met the contact resistance and operational
requirements after testing.
