MIL-DTL-83513G
(3) A pencil type soldering iron shall be used, with temperature regulated to 300C 10C to heat
the test solder cups.
(4) After heating the test solder cups to a solder melt temperature, 63/37 tin-lead type solder
shall be applied to fill the solder cup to capacity which will result in solder wetting the entire
cup surface and forming a solder fill meniscus across the open portion of the solder cup.
(5) The finished solder fill shall be smooth and slightly concave with clear wetting and adhesion
to all internal surfaces of the solder cup. Inspection shall be aided by a 10X optical aid.
(6) Twenty percent, but not less than 7 contacts of test specimens shall be tested.
4.5.14 Vibration. The connector assembly shall be mounted as specified herein and vibrated in
accordance with test procedure EIA-364-28, condition IV. All contacts shall be wired in series with at
least 100 milliamperes of current allowed to flow. A suitable instrument shall be employed to monitor the
current flow and to indicate any discontinuity of contact or interruption of current flow. Requirements shall
be as specified in 3.5.12.
4.5.14.1 Connector mounting. Each receptacle shall be mounted on a suitable fixture, which in turn
shall be attached to a vibration table. A suitable sensor shall monitor the vibration of the receptacles at a
point on or near the receptacle. A counterpart plug shall be engaged with the receptacle and shall be
held by normal locking means. The wire bundles attached to the receptacle shall be clamped to
nonvibrating points at least 4 inches from the rear of the receptacle. The wire bundles attached to the
plug shall be clamped to a vibrating point 4 1/2 inches from the rear of the plug. The clamping length
shall be chosen to avoid resonance of the wire bundles.
4.5.15 Shock. Mated connectors shall be subjected to test procedure EIA-364-27, test condition E.
One shock shall be applied to each direction of the three major axes of the connectors. Receptacles
shall be mounted similar to the mounting specified in 4.5.14.1. Plugs shall be engaged with the
receptacles and shall be held by normal locking means. All contacts shall be wired in series with a
minimum of 100 milliamperes of current allowed to flow and the wire bundles shall be clamped to
structures that move with the connectors. A minimum of 8 inches of wire shall be unsupported behind the
rear of the receptacle and 4 1/2 inches of wire shall be unsupported behind the rear of the plug. A
suitable instrument shall be employed to indicate any discontinuity or interruption of current flow.
Requirements shall be as specified in 3.5.13.
4.5.16 Durability. Counterpart connectors shall be mated and unmated 500 times at a rate of 200
100 cycles per hour in a manner to simulate actual service. Upon completion of durability conditioning,
connectors shall be as specified in 3.5.14.
4.5.17 Salt spray (corrosion). Mated connectors shall be subjected to a salt spray test in accordance
with test procedure EIA-364-26, condition B. After exposure, connectors shall be thoroughly washed with
tap water to remove all salt deposits and then shall be dried in a circulating air oven at a temperature of
38C 3C for a period of 12 hours. Connectors shall then be visually examined for evidence of
corrosion and subjected to the low circuit resistance test specified in 4.5.21, contact resistance test
specified in 4.5.8, and mating and unmating force test specified in 4.5.4. After completion of salt spray
testing, connector shall be as specified in 3.5.15.
