Abstract

This article describes a unique diagnostic test clip and apparatus for microprocessor products. Programmable interface circuits are now widely used in microprocessor base products. Such chips are typically mounted in a forty pin, so-called, dual in-line package. The diagnostics of these products in a working environment are extremely complex not only because of the closeness of the product but of the close proximity of each of the pins.

Test Equipment for Microprocessor Products

This article describes a unique diagnostic test clip and apparatus for microprocessor products. Programmable interface circuits are now widely used in microprocessor base products. Such chips are typically mounted in a forty pin, so-called, dual in-line package. The diagnostics of these products in a working environment are extremely complex not only because of the closeness of the product but of the close proximity of each of the pins.

The test clip and apparatus of the present device comprises a test clip 10 coupled by a flat cable 11 to a display module 12. The clip consists of two interconnected boards 14 and 15 each having ten terminals 16 extending thereon. These terminals 16 are connected via internal leads to the flat cable 11 and the clip 10 is designed with a spring action such that it can be placed over the unit to be tested, so that each of the terminals 16 is in contact with one of the pins of the package being tested. The information is then fed via the flat cable 11 to the display module 12 where the information received from the operation of the unit under test is displayed and the operator can compare it to expected data. The clip allows the user to monitor all the pins in the unit under test and allows any multiple debug or display capabilities to interface therewith.
