A flip-type electronic chip detection fixture

Abstract

The invention relates to the technical field of electronic detection equipment and particularly relates to a turnover type electronic chip detection jig. The turnover type electronic chip detection jig is characterized in that a chip containing cavity for detecting an electronic chip is formed in a jig bottom plate and a turnover pressing plate is arranged above the containing cavity; the bottom end of a rotary pressing device on the turnover pressing plate is connected with a chip pressing block pressing to the electronic chip; when the detection jig is used, the electronic chip is placed into the chip containing cavity and the chip containing cavity has the pipe position effect on the electronic chip, so as to not cause a dislocation phenomenon; the turnover pressing plate hinged with the jig bottom plate covers the electronic chip and is buckled on the jig bottom plate through a pulling buckle; and then the rotary pressing device flatly presses the chip pressing block to the electronic chip, the upper end of the electronic chip is uniformly stressed, and an electronic chip detection part is sufficiently contacted with a detection probe, so that the detection result is accurate and reliable. The detection jig disclosed by the invention also has the advantages of simplicity in operation, convenience for use and long service life.

Description

technical field [0001] The invention relates to the technical field of electronic detection equipment, in particular to a flip-type electronic chip detection jig. Background technique [0002] In the 1990s, with the advancement of integration technology, the improvement of equipment and the use of deep submicron technology, LSI, VLSI, and ULSI appeared one after another. The integration of electronic chips continued to increase, and the requirements for integrated circuit packaging became stricter. increases, power consumption also increases. In order to meet the needs of development, on the basis of the original packaging varieties, electronic chips have added a new variety - ball grid array packaging, referred to as BGA (Ball Grid Array Package). At present, various electronic chips are widely used in various industries in the electronic field: computer , mobile phone, computer north-south bridge, Mp3, MP4, DVD, DVB, printer, communication terminal, industrial control mot...
