Mission Statement:
Currently I am looking for employment with a company that can utilize my skill set and would appreciate my
experience in working with their engineering dept. either as a contractor or direct hire. I have a tremendous amount
of resources and knowledge that I want to contribute to the right firm. I am a team player who wants to contribute,
who works independently with minimal supervision and is capable of multi-tasking to meet projected goals and
schedules.
Professional Attributes:
Highly organized . Diligent . Good Communicator . Good written and verbal skills . Ability to manage multiple tasks .
Strong understanding of Manufacturing and Assembly processes.
Design Strengths:
I have a strong understanding of controlled impedances, differential pairs matching (timing circuits) and RF
design in particular. I have extensive experience working with radio communication (RF), High Speed digital (400
ghz) controller cards, Power Supplies and designs with special shielding requirements for EMI concerns. I have
Flex circuit design experience as well and an understanding of the necessary manufacturing tolerances to take a
design from conception though fabrication and assembly. I have experience in CAM software and can do DFM
checking and panelization, solder paste modification if required.
Work Experience:
I have over thirty years of experience in engineering and PCB design. I have held positions as Drafter,
Designer, Checker and CAD Manager for companies through out my career. I have worked on Top Secret
government projects and have held a secret and classified clearance previously (not currently active). My
experience has been extensive in Areospace and Space flight equipment with zero gravity implications and thermal
swings. In addition I was worked for many years doing RF designs for Cryogenic Wi-Fi filtering systems. I have
done High Speed Digital Design at 400 Ghz with via in pad on micro BGA’s and controlled impedance differential
pairs. (samples are available upon request)
I have worked as a DFM engineer evaluating designs for design errors, potential manufacturing
complications and compliance for testability. I also performed controlled impedance calculations, taking in
consideration layer stack up and copper weight, line width and spacing to ensure the proper impedance calculated
was indeed going to be met as required. Part of my duties was to also panelize designs to accommodate assembly
reflow / wave solder machines during the assembly processes. Create Solder paste Stencils and implement
calculated modifications to prevent solder bridging on fine pitch parts.
With my experience and education in both fields I am able to design smart and effectively in producing high yield
quality designs taking manufacturing and testability in consideration in the forefront of the design process.

2. Employment History:
CLH Design Services 1992-Present
Studio City, CA 91604
I performed several duties beyond the standard duties of PCB Designer at CLH Design. Part of my tasks
were to estimate design efforts and quote jobs. I typically estimate the effort by breaking it down into hours
reflecting each individual effort (i.e. Schematic Entry, Packaging, Placement and Routing etc.) I generate a design
log of the entire design effort to track the progress and make any adjustments necessary to meet the deliverable
target date.
I created and maintained component libraries. I realized the most effective way to reduce the “error ratio” is to
utilize a library with “validated geometries”. The biggest impact in testing any new design is if a “new footprint” has
been built incorrectly. Once used and validated, it is gold and kept in a “released” library that can be used by many
designers. Library Control is instrumental to maintain a high level of integrity in all designs.
Vendor relationships are also critical in providing the necessary tools for a quick accurate build.
Working in concert with your vendors whether it is Fabrication, Assembly or Test Equipment can be an intricate part
of the entire process. The earlier the better in my opinion, communicating with these vendors to what your design
goals are and to validate those goals and approach allows you to go forward with confidence that your design will
be compliant with the specifications and tolerances that will guarantee your design with a high yield and low
tolerance for error.
I have been working as an independent Senior Design Engineer for the following companies reflected in my work
history. I own and operate all my own hardware/software and have been working on and off-site depending on
logistics and necessity.
STONE ELECTRONICS LLC: July 2014- May 2016
13000 SAN FERNANDO ROAD , SYLMAR, CA 91342
Salinity Design: Controller Card with an on board Power Supply section.
The type of circuit designed for this effort can be defined and Analog / Digital with Electromagnetic Interference
(EMI) considerations. This layout is comprised of “through hole” component technology. This is a ruggedized
instrument that is built to take extreme vibration and shock. Testing has been on going by the Navy and has passed
all the required benchmarks.
The composition of this design is as follows: Two signal layers, Two power layers and a Two shield layers.
The shield layers are tied to a isolated ground net that is stitched through out the board utilizing small feed thru
via’s, this technique is in affect creating an electrical shield (can) that will prevent any outside interference (EMI) to
compromise the integrity of the operation of this circuit.
