Experience with HDI, High Speed, HDL, Allegro 16.6, Constraint Manager, Valor, Agile Experience

Infinera – PCB Layout (Contractor) 2016/7 – 2017/1 Use Allegro 16.6 do placement, setup design rules and constraint manager, Routing, import emn/emp for mechanical constraint, generate Fab/Assembly drawings and Gerber for network boards. Qualcomm – PCB Layout 2011/11 –2016/02

Import nets from Orcad CIS or Cadence Concept HDL to Cadence Allegro, create board outline, parts placement, routing, constraints setup, implement DFA/emn/emp mechanical constraint for high speed multi-layer board. Run DRC check and final check with Valor. Generate Gerber, ODB++ and Assembly/Fab drawing with BluePrint, Upload Gerber related files to Fab house and Agile.

Essai – PCB Layout (Contractor) 2010/06- 2011/08

Use Cadence Concept do symbol / schematic capture and Allegro16.3 do PCB footprint creation and layout for Automated Test Equipment (ATE) boards which has BGA, LGA or IC sockets. DFX import / export for mechanical checking.

2020 Lightwaves – PCB Layout (Contractor) 2009/11- 2010/4 Use Orcad CIS 10.3 to create symbols, draw schematics, create net list, and Convert net to Cadence Allegro 15.7 (Editor) Create pcb footprint, do placement, setup design rules, prepare Assembly/Fab drawing for Fiber boards. Foxlink – Testing Technician (Part Time) 2008/03 – 2009/3 Test, debug, fix and report various RMA fax/scanner machines status to meet deadline schedule. Salutron – PCB Layout (Contractor) 2008/11 – 2009/2 Use PadsLogic to draw schematics, create net list, and Convert net to PadsPCB version 2005_SP2 to create footprint, do placement, Generate gerber, Assembly/ Fab drawing for Analog / Digital watch. EndWave– PCB Layout (Contractor) 2007/2 – 2007/9

Use Orcad CIS 10.3 to create symbols, draw schematics, create net list, and Convert net to Cadence Allegro 15.5. (Editor) Create footprint, do placement, setup design rules, route based on heatsink, gasket & wall and generate gerber/ Assembly / Fab drawing for Defense RF board. Use little OrCAD2000i for mechanical and component DFX input / output. Prepare BOM and ECN.

Super Micro – PCB Layout 2005/4 – 2005/8

Use Allegro 15.2 to do placement, constraint setups, high density routing, match length and generate gerber for mother boards.

Advanced Test Services (Service house) – PCB Layout 2004/2 – 2004/5 Use Orcad to create symbols, draw schematics and netin netlist to Cadence Allegro 15.2 (win XP). And create footprints, do placement, route,generate fab/assembly and gerber files for Eagle and Fusion testing board. LSI Logic – PCB Layout (Contractor) 2003/10 – 2003/12 Use Protel to do placement, route and constraints setup for DVD board. Astr Systems (Service house)– PCB Layout (Contractor) 2002/3 – 2003/9 Used Cadence Allegro 14.1 (win NT) to do placement, route, design rules and constraints setup, match delay and impendence control, fab/assembly drawing and gerber files creation for multi layers high density double sided SMT technology communication boards and testing cards. Spectrian - PCB Layout 2001/1-2002/1

Used ViewLogic to create symbols and draw schematics from electrical Engineer’s rough or detailed sketches. Used Allegro 13.6/14.0 (win NT) to create components, route with blind & buried vias, setup design rules and constraints, create prob testing,generate gerber files and create Fab/ Assembly drawing for RF board. Using Matrix system for database maintaining.

3dfx INTERACTIVE–PCB Layout 2000/8-2000/12

Used Allegro 13.6 (win NT) to do placement, route, setup design rules and constraints, do match delay and impendence control, create fab/ assembly drawing and gerber files for multi layer high speed / high density double sided SMT technology graphic cards. Used Cam350 for gerber checking. Gs Technology (Service house) –PCB Layout 1997/8 – 2000/3 Used Pads-Perform/Pwr-PCB and Allegro(Unix) to create footprints, do placement, do mechanical consideration / DRC checking for high density various double sited SMT technology boards and create Fab/Assembly drawing and gerber files. Run ECO report for comparing the new and old design. Coordinated the PCB design between customers and design engineers and check the delivery schedule.

Otter Computer (Service house)– PCB Layout 1995/10 –1996/11 Used PADS2000 and Pads-Perform to design various personal computer Boards like 386/486 mother boards and notebooks.

Cad Science (Service house) – PCB Layout 1990/7 – 1994/5 Used Pads2000 and Calay working station to design various PCB boards.
