AI Technical Summary

Technical Problem

Existing heating methods cannot effectively simulate the local high heat flux density of chips. Traditional simulated heat sources can only achieve uniform heating, which cannot meet the requirements for simulating local hot spots with high heat flux density. Furthermore, real chip testing is costly and time-consuming.

Method used

A non-uniform heating simulation heat source is designed, which divides the region into a high heat flux density region and a low heat flux density region by a metal thin film resistive layer, and uses different electrode groups and power supply pin components to achieve non-uniform heating, simulating the local high heat flux density and overall low heat flux density of the chip. It is fabricated using copper thin film material and magnetron sputtering process.

Benefits of technology

It achieves accurate simulation of local high heat flux density and overall low heat flux density of chips, reduces testing costs and cycle time, improves testing efficiency, and has non-uniform heating characteristics, which can provide the complete thermal boundary conditions of real chips.

Abstract

本发明提供的一种非均匀加热模拟热源包括加热片、第一供电顶针组件及第二供电顶针组件,加热片包括由上至下依次设置的金属薄膜电阻层、第一绝缘层及基底,金属薄膜电阻层划分为高热流密度区、低热流密度区、第一电极组和第二电极组,金属薄膜电阻层裸露表面包裹有第二绝缘层,第一供电顶针组件用于实现第一电极组与第一供电源电连接,第二供电顶针组件用于实现第二电极组与第二供电源电连接。由于第一供电源大于第二供电源提供的电压,高热流密度区不大于低热流密度区的电阻,从而高热流密度区大于低热流密度区的发热量,高热流密度区用于模拟芯片局部高热流密度区,低热流密度区用于模拟芯片整体低热流密度区。
