Harness Board Fixturing with easy-wire Components

 PictureWhen to UseStrengthsWeakness
Traditional Harness Board with On Board Components onboard4 For high volume, low-mix manufacturing when a harness board will be dedicated to a tester.
  • Maximum flexibility
  • No wasted test points
  • Simple fixturing
  • Easy replacement of test connectors
  • Works with standard harness nails
  • Harder to create, duplicate, and maintain
  • Back-wiring required
  • Cost of fixturing discourages testing for low-volume harnesses
  • Few reusable parts
Near Board Components nearboard4 For high and low-mix manufacturing, allowing easy maintenance and sharing of test connectors and their removal before board storage. All of the above plus:
  • Fast fixturing at low cost
  • Removable adapters for faster repair of fixturing
  • Back-wiring might be avoided
  • Connectors can't tilt, which means less flexibility in their position
  • Difficult to tape or tie wires
  • Brackets permanently attached to the board
Above Board Components above-board-4 For high-mix manufacturing.

For quick repair and replacement of components.

All of the above plus:
  • More height for larger connectors
  • Tilt of connectors
  • Clearance for taping and cable ties
  • Back-wiring eliminated
  • Reusable components
  • Brackets are still permanently attached to the board
Grid Board Components grid1-4 For quick-response manufacturing from prototyping and lead production, through volume production using one system. Above Board strengths plus: 
  • Easy mount and removal of shared components
  • Reusable components 
  • Eliminate storage of harness boards
  • Higher component cost must be offset by reusing components and eliminating labor to build harness boards
Screw/Screwless Transition Boards* transitions4 For test connectors that are only to be removed for maintenance.
  • Ideal for traditional, On Board, and Near Board components
  • No wasted test points
  • Handles #14-28 AWG
  • Pattern of connections is difficult to maintain when changing test connectors

*For transition between testers and test connectors on harness boards.
