PC Board Target Dimensions
The spacing for the socketed tip differential probe head is 0.100 inch (2.54 mm).
For soldering on a PC board, the targets can be two vias that can accept the 0.020
inch (0.508 mm) diameter resistor leads. A via of 0.025 inch (0.0635 mm) diameter
is recommended. If soldering a resistor lead to a surface pad on your PC board, the
resistor leads can be bent in an "L" shape and soldered down. A pad size of at least
0.030 x 0.030 inch (0.762 mm x 0.762 mm) is recommended.
Shaping the Resistors
Before installing the 82W resistors (01130-81506) onto your device under test, the
resistor wires must be trimmed using diagonal cutters and bent to the correct
dimensions as shown in
the rectangle of the supplied trim guage. Use diagonal cutters to trim the leads
even with the trim lines.
