Profile:

Expert PCB layout designer.

16+ years of hands on experience as a full time employee with service and product based organisations and 5 years of experience of running own freelancing business. Recently started free lancing again after working at Honeywell for 6 years.

Ability to collaborate and work with domestic/offshore clients and contract manufacturers. Design Tool Experience:

Mentor Graphics PADS

Altium Designer

Mentor Graphics Boardstation

Mentor Graphics Xpedition

Cadence Allegro

Valor

CAM 350

And currently learning Eagle to work for a client Key Technical Skills:

Designed complex multilayer layout (upto 12 layers) with design constraints for Hi speed digital and analog routing using packages like BGA, TQFP etc for thorughole, SMD and mixed designs.

Good understanding of schematic and layout using rule and class based topologies.

Experience of different routing techniques like length matching, guarding, daisy chain routing, differential pair routing,clock signal routing etc for better signal integrity and controlled impedance.

Experience in designs having SDRAM,DDR, Bluetooth 4.0 BLE,WIFI and interfaces like I2C, SPI, USB, PCI Express, NAND flash, Buck-boost SMPS and many more.

Knowledge of layout optimization by proper placement, trace width requirement based on current and implementing noise reduction techniques & emission control for EMI/EMC aspects.

Designing layout for requirement of clearance and creepage to meet UL/CSA safety standards.

Maintaining CAD libraries and creating land pattern as per IPC standard or company standard.

Generate complete documentation package including gerber files, bill of material, ODB++,pick-n-place, IPC net- list, fabrication drawing and assembly drawing.

Designing a data for laser cut stencil by deciding thickness and determining size and shape of aperture for ensuring a high yield surface mount assembly process for RoHS /Non RoHS designs.

Defining layer stack-up in collaboration with PCB manufacturer and pre/post layout signal integrity analysis using Hyperlynx for high speed designs.

Layout design considering DFM,DFA and DFT requirement like orientation of components, spacing between components, placement of fiducials, panel design as per soldering process like reflow/wave soldering, requirement of RoHS/Non RoHS soldering, requirement of Pick & Place machine, test point requirement for ICT etc.

Writing scripts and macro generation using Visual Basic script to automate the process for layout for tools like PADS, Board station.

Programming experience using Visual Basic 6 for customized report generation database for real time data collected by distributed control system and a software for generating engineering documents like wiring diagaram, loop schematic etc for DCS

Configuration of SCADA for plant automation application. Professional Experience :

Work Experience :

Led in-house team of PCB designers, project scheduling and project tracking for outsourced work using tools like issue tracker and for layout design and publishing dashboard for each milestone.

Conduct design feasibility studies to evaluate the PCB design goals for packaging, cost, manufacturing and system performance.

Collaboration with hardware team, Mechanical CAD team, fabrication vendors, assembly vendors, PCB Layout houses and contract manufacturers to ensure highest quality end product for high volume manufacturing by implementing processes.

Involvement in footprint generation as per IPC/Company standard, optimizing component placement and routing of complex multilayer Printed Circuit Boards for overall board size, number of PCB layers, PCB cost, managing ICT requirement, conducting design reviews etc.

Defining best practices and standardizing layout process guidelines, creating templates and updating checklists, preparing SOW, effort estimation for proposal, preparing process map etc. by using six sigma tools.

A valuable problem solver who has ability to design layout for bridging gap between design requirement and manufacturability to overcome and prevent the challenging issues arising on production line and taking prevention action early in design phase to minimize engineering change orders (eco).

Conducted share and learn sessions in Honeywell to share tips and tricks of different tools to fellow engineering team and junior layout engineer.

Additional skills:

Highly competent in face to face meetings with customers and suppliers with a superb ability to explain and document technical issues and solutions.

A confident individual who can teach and communicate well with younger inexperienced engineers whilst remaining open minded to new ideas and design concepts.

Mindset and lookout for optimizing designs for speed, cost and manufacturability. Qualification :

Diploma in Electronics and Radio Engineering with first class distinction (Course eligibility 12th PCM) from Gujarat Technical Board in 1986 with In-Plant training at Vikram Sarabhai Physical Research Laboratory,Ahmedabad
