MIL-E-48630(AR)
3.5.2.8 Detonator fire signal output energy.
The electronic
assembly shall provide energy to fire the detonators when required
as described in the specification. The output energy shall be such
that a minimum of three (3) volts shall be measured no more than
forty (40) microseconds after a fire output signal is generated and
a minimum of two (2) volts is measured at a minimum time of 120
microseconds after the fire output signal is generated. Voltages
shall be measured at the output terminals across a 3.9 ohm + 5%
resistive load (see 4.5.12).
3.5.2.9 Detonator fire signal duration from timer.
3.5.3 Target sensor functioning. The electronics assembly
shall provide a fire signal (para. 3.5.3.1) when subjected to valid
target signatures and not provide a fire signal when subjected to
invalid signature. The specific conditions and the signal limit
under which this function shall occur are specified in drawing
9342576.
3.5.3.1 Sensor output voltage. The output from the target
sensor (test point 1) shall be a minimum of 2.5 volts when the
assembly is subjected to a valid signature as specified in drawing
9342576.
3.5.4 Non-activated voltage. Each battery cell shall be
inactivated and measured less than .005 volts when measured by a
107 ohm input impedance meter (see 4.5.14).
3.5.5 Soldering. All soldered electrical connections shall
comply with MIL-S-46844, MIL-S-45743.
3.5.5.1 Solderability. Electronic and electric assembly parts
that are to be soldered shall comply with the solderability
requirements of MIL-S-45743 and MIL-S-46844 except integrated
circuits shall be tested for solderability using the methods and
acceptance criteria of MIL-STD-883 and diode and transistors shall
be tested for solderability using the methods and acceptance
criteria of MIL-STD-750 provided the leads are not gold plated.
When gold plated leads are used, the provisions of MIL-S-45743 apply.
3.5.5.2 Quality assurance soldering plan. The contractor will
generate a Quality Assurance Soldering Plan that will detail the
overall soldering procedure. This plan shall include detailed
information for handling, cleaning, hand soldering, machine
soldering, process controls including documentation required by
3.4.4 of MIL-S-46844 tool maintenance, flagging procedures for
avoiding excessive defects and all other pertinent QA procedures
relative to soldering. This plan will be generated and submitted to
AMCCOM, DRSMC-QAT-M(D) (see 4.5.22).
3.5.6 Shorting bar continutity. There shall be no more than one
(1) ohm resistance in the shorting bar loop when measured between
the designated terminals (see 4.5.16).
