Part #: EQCD DV-EM Phase B DVT testing
Part description: Micro Co-ax High Speed Cable Assy, 0.8 mm Pitch
v) Test Voltage (VAC) until breakdown occurs
2) MEASUREMENTS/CALCULATIONS
a) The breakdown voltage shall be measured and recorded.
b) The dielectric withstanding voltage shall be recorded as 75% of the minimum breakdown voltage.
c)
The working voltage shall be recorded as one-third (1/3) of the dielectric withstanding voltage (one-
fourth of the breakdown voltage).
INSULATION RESISTANCE (IR):
To determine the resistance of insulation materials to leakage of current through or on the surface of these
materials when a DC potential is applied.
1) PROCEDURE:
a) Reference document: EIA-364-21, Insulation Resistance Test Procedure for Electrical Connectors.
b) Test Conditions:
i) Between Adjacent Contacts
ii) Mated
iii) Mounted
iv) Electrification Time 2.0 minutes
v)
Test Voltage (500 VDC) corresponds to calibration settings for measuring resistances.
2) MEASUREMENTS:
a) When the specified test voltage is applied (VDC), the insulation resistance shall not be less than
1000 megohms.
GAS TIGHT:
To provide method for evaluating the ability of the electrical system to withstand harsh vapors which might
lead to oxide formation that may degrade the electrical performance of the electrical system.
1) Procedure:
a) Reference document: EIA-364-36, Test Procedure for Determination of Gas-Tight Characteristics for
Electrical Connectors, Sockets and/or Contact Systems.
b) Test Conditions:
i) Reagent grade Nitric Acid shall be used of sufficient volume to saturate the test chamber
ii) The ratio of the volume of the test chamber to the surface area of the acid shall be less than 10.
iii) The chamber shall be saturated with the vapor for at least 15 minutes before samples are added.
iv) Exposure time – 55 to 65 minutes.
v) The samples shall be no closer to the chamber walls than 1 inches and no closer to the surface of the
acid than 3 inches.
vi) The samples shall be dried after exposure for a minimum of 1 hour.
vii) Drying temperature 50
о C
viii) The final measurements shall be conducted within 1 hour after drying.
