Parallel connection burning testing system

Abstract

This invention relates to parallel burst recording and test system which expresses each connection place status through one operation circuit board and controlled circuit board interacting to simplify device and operation means, wherein, the machine self has large spring only in need of single machine to allow batch operations to meet large volume production needs.

Description

technical field [0001] The invention relates to the testing field, and relates to a programming test system, in particular to a parallel programming testing system. Background technique [0002] With the increase in the number of integrated components in large-scale integrated circuits (VLSI), the pins of semiconductor components have increased significantly, so BGA (ball grid array) packaging and other structures have to be used, and multi-layer printed circuit boards (MPCB) ), weld the joints to the joints. However, hidden contacts mean that the previous direct contact cannot be used for testing. In order to solve this testing problem, someone proposed a boundary scan (boundary scan) testing technology, which was established by the IEEE Association as the IEEE 1149.1 standard. Through the input and output pins and internal logic The boundary scan unit added between the circuits achieves real-time monitoring of the state of the chip pins, making the boundary scan technolog...

[0005] However, because the PCI slots on the motherboard 10 are limited, they cannot be increased without limit, and the number of connection ports provided by a single adapter 14 also has a limit (8 at present). If a single circuit board is used, 8 hosts must be installed, and a single operator must monitor 8 screens at the same time, which not only increases the cost of equipment, but also causes troubles in space configuration, and undoubtedly increases the chance of errors
