Abstract

An improved device for cleaning probe pins of a probe head assembly is presented. The device includes a first holding plate, a second holding plate and a cleaning cartridge. The first holding plate secures the probe head assembly. The second holding plate secures the cleaning cartridge in proximity to the first holding plate. The cleaning cartridge has a chamber. The chamber includes a cleaning solution and an absorbent pad located therein. The absorbent pad is saturated with the cleaning solution and prevents leakage of the cleaning solution out of the chamber. During cleaning operations, the first holding plate is positioned about the second holding plate such that the probe pins of a probe head extend into and contact the absorbent pad in the chamber. Once contact is established, the cleaning solution acts upon the probe pin tips to remove unwanted debris. A depth of penetration of the pins into the pad is controlled by a surface of the cartridge.

Claims (11)

1. A device for cleaning probe pins of a probe head assembly, said device comprising:

a first holding plate for securing said probe head assembly;

a cleaning cartridge having an upper surface and a chamber and a cleaning solution and an absorbent pad having a top surface, said absorbent pad being located within said chamber, said absorbent pad being saturated with said cleaning solution and preventing leakage of said cleaning solution out of said chamber; and

a vertical guide including a substantially vertically-oriented elongated slot, said first holding plate slidably and pivotally engaging said elongated slot;

means for securing and aligning said cleaning cartridge in proximity to said probe head assembly;

wherein said first holding plate is pivoted about said vertical guide to be placed in alignment with said cleaning cartridge.

2. The cleaning device as set forth in claim 1 wherein said cleaning cartridge includes a removable and reusable cover.

3. The cleaning device as set forth in claim 1 wherein said means for securing and aligning includes a guide extending from said first holding plate and a second holding plate including a slot for receiving said guide.

4. The cleaning device as set forth in claim 1 wherein said means for securing and aligning includes a clamp extending from said first holding plate and a second holding plate including a hole for receiving said clamp.

5. The cleaning device as set forth in claim 4 wherein said first holding plate, said second holding plate and said cleaning cartridge are comprised of a chemically inert material.
