This series was designed for the test of ceramic substrates loaded with components.
Typically such substrates require a very high pointing accuracy of the probe. In
combination with the receptacle S 105.035-L the extension height is 8.0 mm (.315“).
Recommended test pad size ≥ 0.5 mm (20 MIL). Maximum component height on
substrate is 5.5 mm (.217“).
For the installation of the receptacles the mounting plate requires precise drilling. In the fixture business there are some typical base materials used for the pin plates
which are different in drill bit diameters and machining parameters. The table below is showing the recommended drill diameter and the order numbers needed
when ordering drill bits from us. For machining parameters please consult factory.
