Problems solved by technology

[0003] When simulating a car accident, it is necessary to place a variety of sensors in the vehicle. The electrode components on the internal substrate are welded by soldering. After a long period of time and high-density violent impact, the soldering parts are prone to loosening, causing electronic damage. Poor contact of components affects the accuracy of test data. In view of this, the present invention provides a chip substrate, which can reduce the looseness of soldering parts when soldering electronic components and improve the stability after installation.

Abstract

The present invention belongs to the technical field of semiconductor devices, in particular to a chip substrate comprising a substrate body. The surface of the substrate body are provided with a plurality of mounting holes, and the substrate body at the bottom end of the mounting holes is provided with an annular groove. An annular ring is arranged in the annular groove; an annular plate is arranged at the bottom of the annular ring; and the lower surface of the annular plate is flush and fixedly connected with the lower surface of the substrate body. The invention arranges the annular groove and a rubber rod so that when the annular ring is broken after a pin is mounted, the annular ring shrinks and a force applying spring pushes the rubber rod in an elbow to move; the rubber rod is extruded from the elbow and applies a downward thrust to the pin. At the same time, soldering tin is solidified after cooled and is located in the annular groove where the annular ring is broken and shrinks so that the sliding probability of the soldering tin is reduced. Simultaneously the soldering tin is solidified together with a stay cord; an upward thrust is applied to the stay cord by the force applying spring; thereby there is a tension effect on the soldering tin; and the moving probability of a welding part is further reduced.

Description

technical field [0001] The invention belongs to the technical field of semiconductor equipment, in particular to a chip substrate. Background technique [0002] The chip substrate is the packaging substrate, which is a term in printed circuit boards. The substrate can provide electrical connection, protection, support, heat dissipation, assembly and other functions for the chip to achieve multi-pin, reduce the volume of packaged products, and improve electrical performance and heat dissipation. , ultra-high density or multi-chip modularization purposes. [0003] When simulating a car accident, it is necessary to place a variety of sensors in the vehicle. The electrode components on the internal substrate are welded by soldering. After a long period of time and high-density violent impact, the soldering parts are prone to loosening, causing electronic damage. Poor contact of components affects the accuracy of test data. In view of this, the present invention provides a chip ...
