MACHINED ZIF represents a step forward in providing more design flexibility for military and industrial users of circuit board retainers. The ZIF retainer can now be machined directly into the chassis or cold wall without the need for brazing. This manufacturing breakthrough improves chassis producibility, adds structural integrity and provides the best thermal performance of any retainer available. 

Fin pins can be machined to .012 inches with a pitch of 18 fins per inch without brazing. The MACHINED ZIF technology provides up to 45% more heat transfer capability than conventional wedge style retainers. 

The MACHINED ZIF 1/4 turn locking feature enhances product maintainability and never requires a torque wrench when engaging.

Machined ZIF - Design Features

• QUICK LOCKING ACTION
  The locking operation that secures the PCB in the ZIF retainer requires only a 1/4 turn of the rod assembly.
• UNIFORM HEAT TRANSFER
  Uniform clamping pressure eliminates hot spots along the PCB interface producing an even distribution of heat along the entire edge.
• COMPLETE INTERCHANGEABILITY
  ZIF component parts are designed to assure consistent performance and interchangeability of all identical part numbers.
• OPERATING ENVIRONMENT
  MACHINED ZIF characteristics are unaffected by adverse environments typically encountered in military and industrial applications.
• VISUAL INDICATION
  ZIF provides a visual indication that the rods are in the "open" or "closed" position relative to the position of the drive assembly. This indication can be painted yellow upon request.
• MAINTAINABILITY
  The unique design and interchangeability of the like parts make field repairs quick and simple. Repairs can be accomplished without the use of any special tools.
