Has Been Constructed To Provide An Incircuit System That Will Test

An in-circuit test probe apparatus for probing the finely and closely spaced leads of an LSI circuit package in order to monitor the signals on the pins. A magnetic holding assembly is utilized to attach the test probe apparatus to the circuit package which is positioned with a cavity in the bottom of the test probe apparatus. A layer of silicon rubber is positioned between rough and fine ...

Performance Evaluation of In-Circuit Testing on QCA based Circuits ... First a device model of the processor must be constructed (i.e. the sc hematic itself). ... the QCA architecture has been ...

A microprocessor-based in-circuit emulator is described. The emulator is for 6802, 6808, and 6809 microprocessors. It does not operate at full bus speed or execute instructions from the target ...

The author has designed and constructed a test system for the Motorola MC6802 (also suitable for MC6800, except for incircuit testing), employing a MIKBUG 2.0 monitor (Figure 1 ). This system is designed for testing target systems of 1 kbyte or less, but can be adapted for larger systems.

construct. In this paper a method has been ex-amined that can be used to subsequently ana-lyze the reliability of the latest mobile device related materials and design. The prescribed test has been constructed us-ing a cross comparison of pad design, surface finish, solder mask and underfill, measured by drop testing. Based on the resulting data, a

Standalone low-cost interface, controller and emulator for the Apple il Not only does the interface card described by B T G Tan and A K Tan provide the Apple II with parallel ports, programmable timers, serial interface and an EPROM -- it also acts as an independent microcomputer, once it has been interfaced to external devices An I/0 interface card for the Apple II microcomputer is described.

An in-circuit test apparatus having a vacuum chamber between a top plate and a base plate. The apparatus has an adjustable bearing block assembly located at each quandrant to provide a precision alignment between the top plate and the base plate. A continuous double-hollow tube is located in a uniform groove in the base plate and forms a seal when held captive between the top plate and the ...

A minimal memory in-circuit digital tester with vector memory concentrated in a centralized vector processor circuit, eliminating the need for pin memory. The vector processor circuit memory is partitioned into two blocks, a pointer memory and a change list memory. Every vector clock cycle has one pointer memory entry. The pointer memory entry is an address for the change list memory.
