Today, we are gonna introduce the high frequency PCB built on RT/duroid 5880 laminates.
RT/duroid 5880 is one of Rogers’ glass microfiber reinforced PTFE composite which is designed for exacting stripline and microstrip circuit applications.
Why do we use RT/duroid 5880?
Firstly, it has low dielectric constant of 2.2 between 8 Ghz to 40Ghz, and is constant over a wide frequency range. The randomly oriented microfibers help to maintain the DK uniformity.
Secondly, RT/duroid 5880 has low dielectric loss. It’s as low as 0.0004 when 1 MHz and 0.0009 when 10 GHz. Its low dissipation factor extends the usefulness of 5880 to Ku-band and above.
Thirdly, it’s designed for exacting stripline and microstrip circuit applications
We can provide you with double layer board, multi-layer board and hybrid types. Laminate thickness ranges 10 mils to 62 mils with half ounces, one ounce and two ounces. Panel size within 400mm by 500mm is well suited for fabrication. Green colour or no colour is the most used for solder mask and Immersion gold is often chosen for pads finish.
The basic colour of RT/duroid 5880 PCB is black due to the PTFE.
RT/duroid 5880 PCB also has the properties of low water absorption, excellent chemical resistance etc. The typical applications are microstrip and stripline circuits, commercial airline broadband antenna，radar systems, millimeter wave applications, point to point digital radio antenna etc.
