Materials
Taconic RF & Microwave PCB Manufacturing
We manufacture Taconic-based RF, mmWave, and aerospace boards using stocked RF-30/35, TLY/TLY-5A, CER-10, and fastRise® bondply kits. Drawing from Taconic’s datasheets and our RayPCB mirror logs, we maintain plasma, lamination, and RF validation flows that keep loss tangents at 0.0009–0.003 and phase error in check up to 39 GHz.

Why Teams Select Taconic Laminates
Hybrid Cost Strategy
fastRise® bondply joins Taconic RF layers to FR-4 control planes, keeping material BOMs 30–40% below full PTFE builds.
- Documented press/bond curves
- Plane split and keep-out diagrams
- CTE alignment with spread-glass FR-4
High-Dk Miniaturization
CER-10/CER-20 ceramics reach Dk 10–20 for filters, horn feeds, and compact resonators where footprint is critical.
- ±0.25 mil thickness tolerance
- Laser-machined cavities and coins
- Bondable to aluminum backers

Taconic PCB FAQ
Do you stock specific Taconic thicknesses?
Yes. RF-30/35 (10–60 mil), TLY-5A (5–30 mil), fastRise® bondply, and CER-10 (20–40 mil) are on hand. Uncommon lots can be expedited via Taconic distributors.
How do you handle PTFE desmear?
Taconic PTFE is plasma-treated with oxygen/argon mixes; mechanical drills are slowed to reduce smear and plasma recipes are logged per lot.
Can Taconic be hybridized with FR-4 or metal cores?
Yes. We pair Taconic RF layers with spread-glass FR-4 or aluminum backers using fastRise® or low-flow adhesives while tracking press curves and coin interfaces.
