Circuit board holders are a necessity when working on PCB’s, doing cell phone repair, for industrial inspection or in any situation with any object where access to difficult and small places is required. They are used in many industrial applications and especially with stereo microscopes. Easy to use, just clamp the object to be worked on into the spring-loaded clamps, rotate to the desired angle and lock in place. The holders rotate 360 degrees providing easy access to all sides of objects. This is the perfect tool for holding small objects for use with microscopes.
