EMPLOYMENT OBJECTIVE

Senior Electronics Technician seeks full-time position utilizing

Electronics skills.

PROFESSIONAL EXPERIENCE

Field Returns Engineering Technician

August 2010 through June 2011, Research In Motion,

Sunrise, Florida

In the Field Quality and Return Analysis (Deep-Dive) Department helped

analyze the latest BlackBerry smartphone. The analysis involved pre-

production units and field return units from the USA, Canada and Great

Britain. Research and Development and the Materials Laboratory helped us

with some of the problems found with the mechanics, hardware and software.

Used Microsoft Office applications, Oracle based products and in house

software to help analyze and document our findings. The findings were

reported with the objective of raising quality and reliability and lowering

the numbers of field returns.

Electronics Technician IV

June 2003 through July 2009, ADTS and Dynalco, Fort

Lauderdale, Florida

In the Non-Warranty Field Returns Department troubleshot and repaired

mainly microprocessor-based products down to the component level. Various

generations of baler, air/fuel ratio, ignition, governor and steam turbine

controllers, speed switches, temperature scanners and current to pressure

electro-mechanical transducers were worked on. The ignition controllers

included a switching power supply assembly. Most products included modem

circuits to communicate with personal computers. Some units were calibrated

to custom specifications. Agriculture, oil and gas, stationary engines,

trains, city governments and regional government agencies used the

equipment. Used Microsoft Excel, Word and Outlook and communicated with

Customer Service. The average profit margin was 80% and most repairs where

done by the promised time, with almost no returns and no safety incidents.

Senior Electronics Technician

January 1994 through October 2002, Accustaff and Motorola,

Plantation, Florida

In manufacturing troubleshot, microprocessor based two-way radios down to

the component level. I worked on Low Band, Mid Band, VHF, UHF1, UHF2, 800

MHz, R Band and 900 MHz versions. Radios were conventional or trunked,

close or open architecture, secure or non-secure and modulation was analog

or digital. Used communications equipment to test and troubleshoot. Used

computers with DOS and Windows applications to flash, load programs, and

tune and test radios. Used UNIX applications to enter the analysis and

monitor manufacturing processes. Helped fix manufacturing mistakes and

train some co-workers for board analysis. Helped Manufacturing run more

efficient and lower the cost of the product. Found a quicker way to test

secure boards, reducing test time from eight minutes to one minute.

Electronics Technician IV

1978 through 1993, Cordis and Telectronics,

Miami, Florida

In the Development Engineering Laboratory, helped prototype, debug and

characterize cardiac pacemakers. Engineering logbooks were used to document

the sensitivity with adjustable delay step functions and one-shot

haversines. The effects of varying load types, power supply voltage and

operating temperature was documented. Saline was used to simulate the heart

and the human body to document the effects of defibrillation, EMI and RF

electrocautery on the pacemakers. Programming field maps of pacemakers were

documented. A Basic program was written to correct the pacemaker A/D raw

Hex data.

In the Component and Reliability Laboratory helped evaluate components and

pacemakers. Monitored accelerated life tests. Shock, vibration and thermal

cycling were performed per military specifications. Designed with the help

of others, a reliable fixture for testing surface mount capacitors and a

setup that exposed pacemakers to bursts of high gauss AC. Problems with

components failing excessively in Manufacturing were solved by our Team.

Norland digital scope programs and C based RS1 procedures were written and

modified HP Basic ATE manufacturing program to perform uncommon tests.

In the Failure Analysis Laboratory helped analyze returned cardiac

pacemakers. A report was written for every pacemaker analyzed. C based RS1

procedure was written to help interpret pacemaker Hex data.

FORMAL EDUCATION

University of Miami, Miami, Florida

Some second and third year Electrical Engineering courses were completed,

including a microprocessor machine language programming course.

Miami Dade Community College, Miami, Florida

A.A. degree was awarded. The non-technician courses qualified for most of

the first two years of Electrical Engineering at the University of Miami.

A.S. degree in Electronics Technology was awarded.
