Probe cleaning device

Abstract

Provided is a small probe pin cleaner that can reliably clean only a stylus part of probe pin without causing a probe-pin-supporting pinboard to suffer from disadvantage such as solvent crack after being cleaned and is easy to confirm its cleaning. The probe pin cleaner 1 is substantially composed of a bottomed-box-type cleaning container 3 that holds a cleaning fluid 2 such as ethanol; stays 4 that are set on the inner bottom of the cleaning container 3 and horizontally support a pinboard PB with its downward probe pins PP; an outer box 6 having an upper opening edge part 6a which supports the outer edge 3b of the upper opening port 3a of the cleaning container 3 through a shock absorbing material 5; and an ultrasonic vibration generator 7.

Description

technical field [0001] The present invention relates to a non-contact probe cleaning device that cleans a cleaning jig without contacting a probe fixed to a socket. Background technique [0002] The live test is used to measure the electrical parameters between the terminals of the printed circuit board on which the chip components are mounted to check for poor wiring, wrong installation, or defective components. In the electrification test, a test jig (hereinafter referred to as a socket board) for fixing a plurality of probes corresponding to respective terminals of a printed circuit board to be tested is used. In the case where the plug board is slidably held in the lengthwise direction of the probe by a sliding part composed of a bush and a coil spring arranged in the bush, the probe can be slid in a specified position during the continuity check. The pressing force is in contact with each terminal of the printed circuit board. However, after the continuity check, the ...

AI Technical Summary

Problems solved by technology

In this case, since the corroded coil spring prevents the sliding probe from sliding a predetermined distance, there is a problem that the contact between the probe and each terminal of the printed circuit board is insufficient, and precise continuity inspection cannot be performed.

In addition, when using isopropyl alcohol (IPA) or glycol ether (GE) as a cleaning solution, it is difficult to use and purchase, and there are cracks caused by the penetration of the cleaning solution into the plug board, etc. The problem of damage (hereinafter referred to as solvent cracking) requires a separate device for spraying cleaning liquid and cleaning air, so there is a problem of increasing the size of the device itself

In addition, in the conventional probe cleaning device, the customer has to check the fine probes visually or with a magnifying glass for the dirt falling off, so there is a problem that it is troublesome to check after cleaning.
