Placement optimization, Routes editing, DRC, Library management, Post processing for printers/pen and
photo plotter outputs.
 Gerber view analysis using tools like GC-Prevue and creating CNC data in Exellon format.
 Apart from the layout designs I have done post layout simulation, which includes cross talk, signal
reflection etc. Electromagnetic interference and compatibility (EMI/EMC) are performed for various
designs and components, placement affects are minimized for better design performance and reliability.
 Worked on standards of CSA (Industrial control equipment standard), UL 508C (Power conversion
equipment).
 Had done of projects under the CSA standards to meet the specifications by customer requirement & our
own products like AC/Variable Frequency Drives.
 Knowledge on the IPC-7351, IPC-2221 standards for the footprint creations and board design.
 Analyzing the respective board problems, test made by engineers and made corrections of schematics and
PCB’s when required.
 Searching for components as per product specification requirement for Analog & Digital designs and
maintained symbol libraries for schematic symbols and footprint libraries for various PCB designs.
 Updated schematics of engineering process and preparing the products documents for ISO 9001:2008
audit.
