摘要

本文介绍了一种用于pga型高速多芯片模块(MCM)的同轴表面安装连接器的试验设计。为了保证安装在印刷电路板上的MCM的可测试性和连接可靠性，需要MCM连接器。我们的连接器由一个同轴元件，一个由导电树脂制成的公共接地外壳和一个接地接触弹簧板组成。它有68个信号接点。通过实验和仿真研究了该连接器的性能。每个信号引脚的插入力仅为53gf左右。特性阻抗从45.6 /spl ω /到61.4 /spl ω /。两个触点之间的平均电阻为28 m/spl ω /，偏差小于±5 m/spl ω /。在1.0 GHz时测量到的插入损耗为-0.4 dB。串扰噪声小于1.2%。该原型连接器的脉冲传输速度高达1.2 Gb/s，表明它适用于高速mcm。

Coaxial SMT module connector for high-speed MCM

This paper describes a trial coaxial surface mounted connector for PGA-type high-speed multichip modules (MCM). An MCM connector is needed to ensure testability and connection reliability of MCMs mounted on a printed circuit board. Our connector consists of a coaxial elements, a common ground housing made of conductive resin, and a ground contact spring plate. It has 68 signal contacts. We investigated the performance of this connector by experiment and simulation. Its insertion force is only about 53 gf per signal pin. The characteristic impedance is from 45.6 /spl Omega/ to 61.4 /spl Omega/. The average resistance between two contacts is 28 m/spl Omega/ with a deviation of less than plus or minus 5 m/spl Omega/. The insertion loss was measured to be -0.4 dB at 1.0 GHz. Crosstalk noise is less than 1.2%. This prototype-connector transmitted pulses of up to 1.2 Gb/s, showing that it is applicable to high-speed MCMs.<>
