DEVELOPED Microsoft 'M-Basic' Reliability Estimation program for Electronic/Electrical Components. Their Stress factors gave MTBF for Circuits, Sub-Systems and Systems as part of FMEA studies in iterative loop. Prior Circuit Audit and Reliability Analysis stopped Design Faults entering Company System. Final Audit and Analysis was included in the Company submission to the MOD. Components were ICs, Transistors, Diodes, Zeners, Opto-Electronics, Capacitors, Resistors, Connectors, etc.

DEVELOPMENt of Test Circuits using SPICE Software.

A LOGICAL REQUIREMENT for Analysis was Component Search, supplied for BSI by CODUS Data-bank, a part of Sheffield University. Info was Gate Count, Power, Thermal Resistance and Quality Factor. This complexity required a supervisory body, the CODUS Committee, of which I was a Member.

IN-HOUSE DESIGN SEMINARS included my Design Fault Module. I also instructed junior engineers.

APPENDIX 1 - DESIGN POINTS (observed during Design Audits up to February 1989)

1.1 Observe second sourcing and pin-for-pin compatibility.

1.2 Don't use obsolescent components.

1.3 Use MIL or Hermetic components.

2.1 Temperature Coefficient of 'Zero' Tempco Reference device run at high currents is not Zero.

2.2 Overloading of Hysteresis circuit may cause it to oscillate. Its fault-finding is then poor.

2.3 Leave adequate Voltage stress margin for Diodes or Capacitors.

2.4 Don't parallel base-emitter circuits. One transistor starves other of drive.

2.5 Put resistor between ground & PSU voltage pot to limit O/P Volts. Shunt pot, cutting effect of o/c wiper.

2.6 In capacitor discharge circuit use FET (or Bi-polar + series resistor)

2.7 Protect CRT Circuits from FLASHOVER/BREAKDOWN and shorten protection current paths.

2.8 Observe Relay contact ratings.

3.1 Drive devices correctly. Overloaded 0PT0-Coupler gives indeterminate output.

3.2 LED indicator is barely visible if it is driven too lightly.

4.1 Take un-used TTL/STTL I/Ps to +5V via Resistor. A wire link is 0K for LSTTL.

4.2 Square up ramp/exponential waveforms with Hysteresis circuit before logic.

5.1 Use correct capacitor value ratio in voltage doubler circuits.

5.2 Use correct feedback network impedance for amplifiers - not too low/high.

5.3 Limit adjustment of timing circuits to minimum advisable - watch o/c wiper.

6.1 Use one Zener as reference in symmetrical +/- dc supply for sensitive circuits, to give high CMRR

6.2 Ensure lines from transmitter to receiver are balanced.
