Adjustable Hold-Down Gates enable the user to position adjustable fingers for uniform distribution of pressure on the UUT surface. Perfect for use on vacuum fixtures designed to test PCBs with open vias. Uniform pressure holds the PCB tight against top plate gasketing, while allowing the PCB to contact and deflect spring probes. Adjustable in X, Y and Z axes. Gate opens to 90°. Gas spring holds gate open at any angle. Quick-release handle locks gate in position for testing.
Adjustable hold-down fingers with Delrin tips are offered in four styles. Optional 1/2" riser frames and riser fingers accommodate tall components. Gate components are aluminum, steel and composite. Each gate is shipped completely assembled with instructions for installation on the fixture. Hold-down fingers are sold in packages of 10.
An optional sealing package is recommended for applications that require isolation of probes from vacuum. The package includes the gate, a Twin-Seal gasket and 3/8 G-10 stiffener plate.
