Request Information

GSC uses a variety of materials as fixture bases and other pieces. Most of the materials used have the following general characteristics. See the links below for technical data from some of the manufacturers.

  • ESD materials protect sensitive components
  • High strength to withstand repeated use
  • Lightweight, easy to handle
  • Withstands high temperatures required for PCB processing without warping or delaminating
  • Low heat absorption allows quicker operator handling and cycling
  • Chemical resistance ensures long fixture life
  • Resistance to thermal shock allows retention of dimensional stability and flatness

Request Information

#0

The "standard" PCB hold-down. Spring-loaded, rotates 360 degrees. Rounded feet always maintain downward pressure on PCB. Design provides the ability to hold two PCB's per hold-down. Easily rotated by hand, or by using our special hold-down tool designed to make it easy for operators wearing gloves.

 
Hold Down #0

#1

Spring-loaded. Rounded foot always maintains downward pressure on PCB. Used where space requirements do not allow full 360-degree rotation. Easily rotated by hand, or by using our special hold-down tool designed to make it easy for operators wearing gloves.

 
Hold Down #1

puller

Spring-loaded, below-surface PCB hold-down for SMT applications. Locating pins in the puller engage into tooling holes in the PCB. The only choice for thin board or flex applications. Locates accurately and repeatedly for screening and placement processes.

pusher

Spring-loaded, below-surface PCB hold-down for SMT applications. A great choice whether or not tooling holes are available in the PCB. Force is applied to the edge of the PCB. Locates accurately and repeatedly for screening and placement processes.
