AREAS OF EXPERTISE

Reliability & qualification testing, and reliability prediction

Defined and managed qualification programmes for processes and components for major space

electronics projects, to customer specifications, including an emergency repair process which saved a

major Com Dev project from defaulting, (Com Dev and MDA)

Defined and carried out solder joint reliability testing on a flip chip on low fired temperature ceramic

assembly. (BreconRidge)

Defined and managed qualification programmes for optical and electronic modules to Telcordia

standards (BreconRidge, Nortel Networks)

Defined and managed a qualification programme for a military product (Active Phase Array Radar

modules) to customer specifications. (Nortel Networks)

Carried out reliability prediction for telecom products to Telcordia SR-332 (BreconRidge, and as a

consultant)

Carried out reliability predictions & reliability testing for thick film hybrids for an airborne application,to Mil.Hdbk.217 (Marconi Avionics)

Failure analysis

Organised the successful failure analysis of products from manufacturing, qualification testing, and the

field, eg:

- Contamination of passive components causing epoxy joint failure. (BreconRidge)

- Die attach failures, due to faulty die processing, two occasions, different root cause. (Nortel

Networks)

- Laser diode failure, traced to contamination during module bake out. (Nortel Networks)

- Optical train failure, due to inappropriate use of epoxy (Nortel Networks)

- Failure of fluxless soldering operation due to inappropriate base metallisation. (Nortel Networks)

- Intermittent failure of contact assembly of sealed X-ray tube. (Marconi Avionics)

Qualified in acoustic microscopy, carried out 90% of department’s work in this area, in incoming

inspection, process quality, and failure analysis. Trained two technicians to do specific acoustic

microscopy inspections. (Nortel Networks)

Defined and managed a study to assess whether a particular silver loaded epoxy would adhere to solder.

(Nortel Networks)

New Product Development and Introduction

Worked on the development of a pilot line for the assembly of laser modules for external sales.

Responsible at this time for process development, line management, some line operations and

documentation. (Nortel Networks)

Managed the transfer of this line to the U.K. facility of Nortel (Paignton), including operator training

and managing the qualification build.

Designed a low cost alternative to the pin grid array package, and set up manufacturing facility for its

assembly. (Nortel Networks)

Introduced new technology where appropriate, eg:

- Acoustic microscopy (Nortel Networks)

- Vapour Phase Reflow Soldering (Marconi Avionics)

Introduced surface mount technology to the company for the assembly of prototype equipment, and

managed the assembly of:

- Prime Fourier Transform Analyser for an airborne application.

- Display drivers for a battlefield radar application.

(Marconi Avionics)

Supplier Quality Engineering/Manufacturing Support

Audited suppliers, and assisted the quality systems department in auditing suppliers. (Nortel, Gennum,

Com Dev)

Qualified new processes at existing suppliers. (Gennum)

Prepared manufacturing documentation, procurement specifications, inspection criteria and other

documentation as required. (Nortel, BreconRidge, Gennum, Com Dev)

Disposed non-conforming material reports, (NCR’s) and raised and resolved supplier corrective action

reports (SCAR’s) when required. (Gennum)

Disposed discrepancy reports (DR’s) raised by inspectors and assembly operators, as required, and participating

in materials review boards (MRB’s) with other engineering functions if necessary. (Com Dev)

Audited sub-contractors’ documentation for three communications satellites. (MDA)

Component Engineering

Established RoHS compliance of family of optical modules (Gennum)

Checked RoHS compliance of components in the Nortel database, finding alternatives where required.

Checked supplier information against Nortel requirements for alleviating tin whiskering

Carried out background research into lead free solder joint reliability to refute Verizon statement that

lead free assemblies were not reliable.
