The more detailed information aboout RT/duroid 5880LZ High Frequency PCB

  • November 16. 2022


There is a type of lightweight high frequency circuit board: RT/duroid 5880LZ PCB.


RT duroid 5880LZ PCB


Rogers RT/duroid 5880LZ laminates are filled PTFE composites designed for exacting strip-line and micro-strip circuit applications. They contain a unique filler that results in a low density, lightweight material for high performance and weight sensitive applications.


Let’s see the data sheet of RT/duroid 5880LZ material.


RT duroid 5880LZ PCB DATA SHEET


RT/duroid 5880LZ laminates have very low dielectric constant of 2.0 +/-0.04 and low dissipation factor ranging from .0021 to .0027 at 10GHz.The very low dielectric constant is uniform from panel to panel and is constant over a wide frequency range. Its low dissipation factor extends the usefulness to Ku-band and above.


The next one is thermal coefficient of dielectric constant (TCDK). The TCDK value is 20 ppm/°C from -50°C to +150°C. This is a very good value for our designers. Ideally, TCDk should be 0 ppm / ℃, that is to say, Dk does not change with temperature. So a TCDK value less than | 50 | ppm / ℃ or lower can be considered good.


RT/duroid 5880LZ has low density of 1.4 gm/cm³. This is lower value comparing with other Rogers materials, for example, RO3000 series are 2.1 to 2.8gm/cm³, RO4000 series are 1.79-1.86gm/cm³, RT/duroid 6000 series are 2.1 to 3.1gm/cm³


RT duroid 5880LZ PCB Capability


For RT/duroid 5880LZ PCBs, we can provide you with single layer board, double layer board, multi-layer board and hybrid types. RT/duroid 5880LZ PCBs have wide thickness. These are the standard thickness such as 10 mils, 20 mils, 50 mils and 100mils for our designers.


Finished copper on PCB is 1oz and 2oz. Our maximum PCB size on high frequency materials is 400mm by 500mm, it can be a single board in the sheet and also can be different designs in this panel.


Solder mask of green, black, blue and yellow etc is available in house. There’s immersion gold, immersion silver, immersion tin, bare copper etc. for pads plating.


RT/duroid 5880LZ has Z-axis coefficient of thermal expansion (CTE) at 40 ppm/°C. This is a low value that ensure its reliable plated through holes.


When ordering RT/duroid 5880LZ PCB, it is important to specify the dielectric thickness, weight of copper foil required and surface finish.
