WaveLink Medium-Bandwidth (8-13 GHz) Differential Probe

1. Remove the old resistor tip and any remaining solder from the long solder pad using a fine tip

soldering iron taking care not to de-solder the SMT resistors.

2. Use a soldering iron to pre-tin the pad. Wash the area with isopropyl alcohol to remove any

residual flux.

3. Align the damping resistor lead with the end of the tin pad and solder in place running the lead

along the pad and over the via. Avoid using excessive amounts of solder. Use the photographs
in this topic as a reference for the proper amount of solder.

4. Verify the following dimensions for:

Resistor Lead Length

0.090 +0.000 / -0.010 (inches)

2.286 +0.000 / -0.254 (millimeters)

Resistor Gap to PCB Edge

0.050 - 0.025 (inches)

1.27 - 0.635 (millimeters)
