Rogers RO5880 is a high-frequency laminate from Rogers Corporation, known for its exceptional dielectric properties, low signal loss, and mechanical stability. It’s especially favored in microwave, RF, and aerospace applications, where signal integrity and thermal stability are critical.
What sets Rogers 5880 apart is its low dielectric constant (Dk ≈ 2.2) and ultra-low dissipation factor (Df ≈ 0.0009 @ 10GHz), making it ideal for high-frequency PCB applications where performance cannot be compromised.
The thickness options available for Rogers 5880 provide designers with the flexibility to optimize for electrical performance, mechanical needs, and cost.

---|---|---|
0.005″ | 0.127 mm | 0.5oz/1oz rolled or electrolytic |
0.010″ | 0.254 mm | 0.5oz/1oz |
0.020″ | 0.508 mm | 0.5oz/1oz/2oz |
0.030″ | 0.762 mm | 1oz/2oz |
0.060″ | 1.524 mm | 1oz/2oz |
The selection of thickness impacts many critical parameters — signal loss, mechanical integrity, thermal behavior, and cost.
One of the primary drivers behind choosing a particular thickness is insertion loss. As the substrate thickness increases, microstrip line width must also increase for impedance matching, which can result in more copper loss.
However, thicker laminates reduce dielectric losses due to increased separation from the ground plane.
Thinner substrates: Lower copper loss, more dielectric loss
Thicker substrates: Higher copper loss, less dielectric loss
This balance is critical in RF designs and is usually evaluated using simulation software such as HFSS or ADS.
Mechanical flexibility is essential in applications like flex-to-install microwave modules. Thinner options, such as 0.005″ and 0.010″, offer excellent bending capabilities and are suitable for compact or curved assemblies.
Thicker laminates, while offering better rigidity, may crack under stress or require larger enclosures.
From a cost standpoint, thinner laminates are generally less expensive in terms of raw material. However, they may lead to higher fabrication complexity, particularly in multi-layer boards.
On the other hand, thicker boards may increase material cost but reduce labor costs due to better handling and lower risk of warping.
For cost-sensitive designs, it’s crucial to optimize not just material cost but the total cost of ownership, including yield and scrap rates.
When selecting a Rogers 5880 thickness, consider the following:
Operating frequency: Higher frequencies favor thinner substrates.
Power handling: Thicker laminates spread heat better.
Bend radius: Flexibility needed?
Connector type: Some connectors require specific thicknesses.
Stackup design: In multilayer PCBs, how does thickness fit into the overall profile?
Consulting with experienced PCB manufacturers like SQ PCB can simplify this process. Their engineering teams help evaluate the electrical and mechanical constraints of your specific application and suggest the best-fit thickness.
Designers must also consider environmental reliability:
Thinner substrates are more prone to moisture migration unless laminated properly.
Thermal expansion is lower in thicker laminates, improving dimensional stability.
Rogers 5880 has low outgassing properties, making it suitable for aerospace and space applications.
DFM considerations are critical when working with Rogers 5880:
Etch compensation is more critical in thinner cores
Lamination cycles may differ depending on thickness
Drilling tolerances must be adjusted based on core rigidity
Ensuring alignment between design intent and manufacturing capability will ensure a successful outcome.
The substrate thickness can influence component pad designs and performance:
SMA connector pads need specific dielectric heights
Passive filter integration requires careful tuning with thickness
High-frequency op-amps and MMICs perform differently across thicknesses
In patch antennas:
Thinner substrates yield smaller antennas with lower efficiency
Thicker laminates improve bandwidth and gain but may introduce surface waves
Antenna designers often test multiple thicknesses to achieve a balance between performance and size.
Transmission line structures such as microstrip, stripline, and CPW are sensitive to substrate thickness. Adjusting thickness alters:
Impedance
Coupling coefficient
Return loss
Optimization often requires iterative tuning — a process accelerated by working with vendors like SQ PCB who understand RF nuances.
When using Rogers 5880 in regulated industries:
IPC-6018 for high-frequency boards
MIL-PRF-31032 for military
RoHS and REACH for environmental compliance
Thickness affects not just the electrical properties but also testability and compliance pathways.

---|---|---|
Signal Loss | Moderate | Low |
Flexibility | High | Low |
Cost | Low Material / High Fabrication | High Material / Low Fabrication |
Thermal Stability | Medium | High |
Connector Compatibility | Standard | Enhanced |
No one-size-fits-all solution exists — simulation, prototyping, and collaboration are key.
When choosing among high-frequency laminates, designers often compare Rogers 5880 with alternatives like:

Frequently Asked Questions (FAQs)
1. What is the difference between rolled copper foil and electrolytic copper foil?
Rolled copper foil is produced by mechanically rolling copper into thin sheets, offering better surface quality and mechanical strength. Electrolytic copper foil is deposited via an electrolytic process and is more flexible and cost-effective.
2. Can I use Rogers 5880 in multilayer stackups?
Yes, but it must be bonded using compatible low-loss prepregs. Compatibility and proper lamination cycles must be confirmed with your fabricator.
3. How do I control impedance when changing thickness options?
Use simulation tools and impedance calculators. Adjust trace width to compensate for dielectric thickness.
4. Is Rogers 5880 suitable for high-power RF circuits?
Yes, especially the thicker variants (0.030″+) that offer better thermal management and dielectric breakdown resistance.
5. Does Rogers 5880 absorb moisture?
Very minimally (0.02%). It’s ideal for outdoor and aerospace environments due to its hydrophobic nature.
