PN 151-853-A www.cascademicrotech.com Pyramid Probe Card: P800-S Online Cleaning• 1

Objective

Particulate contamination can build up on the probe face and tips during probing. In some cases, particulate contamination

may go unnoticed by the user, while in others it can cause persistent open channels. Large, hard particles can crush probe

tips and are a leading cause of premature, catastrophic probe card failure. This application note describes the recommended

online cleaning methods for Pyramid Probes with a steel plunger stack, for example the P800-S (see Figure 1), when probing

solder balls.

This application note starts with some general information regarding contaminants that may be found in probing

environments. It then describes Cascade Microtech’s recommendations for online cleaning methods and a proposed

cleaning recipe. Finally, a procedure for determining the optimum value of online cleaning parameters is described.

Contaminants

Contaminants on Pyramid Probes can be divided into two general classes:

• Particulate contaminants

• Resistive-buildup contaminants

Particulate Contaminants

Particulate contamination can build up on the probe face and tips during probing. In some cases, particulate contamination

may go unnoticed by the user, while in others it can cause persistent open channels. Though unlikely in solder ball probing

applications, large, hard particles can crush probe tips and are a leading cause of premature, catastrophic probe card

failure.

Once particles have been transferred to the membrane, they are best removed by using the offline cleaning brush supplied

with your core. This procedure is described in the application note titled Pyramid Probe Cores Off-line Cleaning With Brush.

The best solution for particulate contamination, however, is removal of the particles at their source. A few simple

precautions can protect Pyramid Probes from particulate damage. To avoid accidental damage to the probe core:

• Probe in a cleanroom environment.

• Use extreme caution when probing correlation wafers.

• Do not load or unload probe cards with the wafer on the chuck.

• Do not share brushes between Pyramid Probes and other probe card technologies.

• Do not touch the membrane, even with gloved hands.

• Do regular preventative maintenance to clean the wafer area of the prober.
