一般有使用到無(wú)線通信的產(chǎn)品，通常都會(huì)在電路板上設(shè)計(jì)屏蔽框(shielding FRAME)來(lái)隔絕電磁干擾(EMI)，現(xiàn)在有些腦筋動(dòng)得快的廠商想出了使用夾子(clip)來(lái)取代屏蔽框的方法，這種夾子不但可以使用SMT打件，而且體積小所以不怕變形。這就是傳說(shuō)中的屏蔽夾了。

The LPC1700 Ethernet block contains a full featured 10 Mbps or 100 Mbps Ethernet MAC (Media Access Controller) designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control FRAMEs, hardware acceleration for transmit retry, receive packet filtering and wake-up on LAN activity. Automatic FRAME transmission and reception with Scatter-Gather DMA off-loads many operations from the CPU.
