PN 153-691-2 www.cascademicrotech.comI Pyramid Probes: Used Core Inspection• 1

This guide describes the visual inspection process for used Pyramid Probe cores. A Pyramid Probe core is considered

“Used” once it has touched down on a wafer. Visual inspection should be performed first visually, and then with a

microscope. The recommended procedure employs two microscopes:

This guide describes the visual inspection process for new Pyramid Probe cores. Inspection should be performed first

visually, and then with a microscope. The recommended procedure employs two microscopes:

When saving photos, be sure to include the serial number in the file name.

Use the Pyramid Probes Certificate of Conformance to verify the following:

• The serial number on the core frame matches the Pyramid Probes Certificate of Conformance.

• The product name on the Pyramid Probes Certificate of Conformance matches the product to be tested.

Step 1: Edge Sense Inspection

Pyramid Probes used on manual probe stations have an edge sense type mechanical switch installed. This step applies

only to manual probe stations.

Pyramid Probes used on manual probe stations have an edge sense-type mechanical switch installed. The edge sense

needle contacts a glass pad on the spring in some Pyramid Probes. When installed on larger frame cores, the edge sense

needle contacts the core spring directly. This step applies only to manual probe stations.

Low-magnification microscope

(with a large working space)

High-magnification microscopes

• Commonly used for PCB inspection and

soldering stations

• Used for inspecting the entire probe, core

window, components and membrane wing

• Magnification range should be approximately

7x to 90x

• Used for inspecting the probe face, probe tips

and beams

• Recommended microscope objectives include

5x, 20x, and 50x

Inspection Area Criteria

Edge Sense

(if glass pad is

installed)

Are there cracks in the glass pad?

Contact local support for instructions.

Is the glass pad securely in place?

Contact local support for instructions.

Is the needle touching the glass pad, and roughly centered?

Contact local support for instructions.
