Customer Need

Customer had a window of opportunity to present a new design for evaluation and sale if AVID could develop prototypes in record time.  Knowing AVID has on-call resources that can respond immediately, they initially contacted AVID on a Thursday for ultra-fast design services.  Start data wasn't delivered to AVID until the next day, late Friday afternoon.

AVID's Solution

Utilizing three of AVID's professional design staff to work Friday night through Monday morning, AVID was able to coordinate the design efforts around the clock to meet the time-critical delivery to the customer with 100% accurate PCB layouts by first thing Monday.

Value Added or Technologies Applied

  • Ultra Fast Delivery
  • Instant On-Call Start
 
 

Project

Multi-Layer High-Speed Digital Printed Wiring Board

Application

Custom Computing System

Customer Need

Customer's engineering team required expertise in PCB layout of a controller board with large FPGAs, DDR, giga-bit Ethernet, USB and compact flash. The engineer responsible for the project relied primarily on AVID for development of routing constraints for circuit function and performance.

AVID's Solution

Utilizing our expertise from completing hundreds of printed wiring board layouts, AVID was able to fully define the routing constraints as well as optimize the stack-up for improved signal integrity. AVID was also able to identify several schematic connection issues and improvements that were able to be corrected before the layout was completed. Ultimately, AVID saved considerable time and money for the customer by avoiding costly board fabrication re-spins and multiple assembly cycles.

Value Added or Technologies Applied

  • Controlled Impedance
  • Pre-Layout Simulation
  • Design Rule Constraints
  • Post-Layout Crosstalk Analysis

Project

Complex, Digital Printed Circuit Board with Radio

Application

Networking Communications

Customer Need

A new start-up company faced with a critical time-to-market schedule to introduce a new product at an industry trade show required on call services to meet schedules.

AVID's Solution

AVID provided complete library development to IPC-7351A standards and PCB layout and simulation services for signal integrity verification of DDR2 memory. Within the layout, AVID utilized high-speed processor/dual DSPs, each with DDR2 memory, and applied extensive attention to thermal management. The radio layout proved extremely challenging due to the small form factor. The unit was completed and demonstrated successfully, leading to a promising new product introduction.
