Kit Size

Choose a kit size based on the size of your printed circuit board to be tested.

1Complete Kit Only

Semco Series 71 Fixtures are only offered as a Complete Kit. For an Upper Head Assembly as shown below, please see our Series 11 MT Mechanical Test Kits..


Stripper Plate

A Stripper Plate is a spring-loaded FR4 plate that helps support the unit under test (UUT). It also protects the probes from damage.

ESD Protection

The ESD option is recommended when there are static sensitive devices on the U.U.T.  It consists of a Static Dissipative laminate bonded to the FR4 probe and stripper plates.  The Polycarbonate lid is also ESD coated.

Pan Depth

The sheet metal pans provided on Semco kits are available in different depths, allowing components, cooling fans, or additional hardware to be installed inside the pan.

Gas Arm / Carlson Hinge Spring Supports

The Gas Arm lid option replaces the standard Carlson spring hinges.


When the Microswitch opton is installed in the fixture, it signals "Begin Test" when actuated by closing the top lid.

Riser Blocks

Riser Blocks raise the polycarbonate lid to accommodate tall components on the UUT (Unit Under Test).  Riser blocks are recommended when you have components taller than 1.2".
