铁木电子最近，使用能够具有44 GHz的高性能弹性体，非常低的电感，高耐力和广泛的温度应用引入了一种新的QFN插座设计。SMP-QFN-8019插座设计为9.1×14毫米封装尺寸，并以高达44 GHz的带宽操作，插入损失少于1dB。接触电阻通常为每引脚15毫米。插座在所有连接上都用44 GHz带宽连接所有引脚。插座安装在目标PCB上，没有焊接，并使用机械硬件进行安装。插座由带切割的摩托材料构造，以适应PCB顶部的RF痕迹。
The SMP-QFN-8019 socket is constructed with high performance and low inductance elastomer contactor. The temperature range is -55 C to +150 C. The pin self inductance is 0.10 nH and mutual inductance of 0.007 nH. Capacitance to ground is 0.069 pF. Current capacity is 4 amps per pin. It comes with a protective plunger matrix (a gold plated copper cylinder) that sits on top of the conductive silver columns. This plunger matrix protects the conductive silver columns from contamination due to various solder ball interfaces. A quickly replaceable plunger matrix enables minimal downtime during final production test. Silver column with plunger matrix contact is rated for >500K cycles.
Pricing for the SMP-QFN-8019 is $2345 each at qty 5; with reduced pricing available depending on quantity required.
