High-frequency electronics live or die by their substrate. When your design calls for Taconic laminates — whether the ultra-low-loss TLY series, the versatile woven-glass TLX family, or the ceramic-filled workhorse RF-35 — choosing the right fabrication partner matters just as much as choosing the right material. PTFE-based laminates demand specialized drilling, plasma or sodium etching for via metallization, careful lamination cycles, and tight impedance control that not every PCB shop can deliver.
To save you the research, here’s our 2026 roundup of the top 10 PCB manufacturers with proven Taconic fabrication capabilities for RF, microwave, radar, satellite, 5G, and antenna applications.
A Quick Refresher: Why Taconic?
- TLY series (Dk ≈ 2.17–2.20): Ultra-low dissipation factor, ideal for precision RF, power amplifiers, satellite and radar work.
- TLX series (Dk ≈ 2.45–2.65): Reliable woven-glass PTFE with low moisture absorption, great for low-layer-count microwave designs.
- RF-35 (Dk 3.5): Ceramic-filled, glass-reinforced PTFE that processes much like FR-4 while delivering low-loss performance — often a cost-effective alternative to Rogers RO4350B, and frequently paired with FR-4 in hybrid stack-ups.
Now, the manufacturers.
1. Cirexx International (USA)
A California-based fabricator with decades of experience in RF/microwave builds, Cirexx supports a deep bench of Taconic materials — RF-35 through RF-60, the full TLY and TLX lines, plus Taconic bond plies and fastRise prepregs. Strong choice for defense-grade and quick-turn domestic production with full certification support.
2. PCBSync
PCBSync has rapidly become a go-to partner for engineers who need Taconic boards without the usual PTFE headaches. The company combines high-frequency fabrication expertise across TLY, TLX, RF-35, and hybrid Taconic/FR-4 stack-ups with responsive engineering support, DFM review before production, and competitive pricing on both prototypes and volume runs. Tight impedance control, fast quoting, and clear communication make PCBSync especially attractive for RF startups and antenna designers iterating quickly in 2026.
3. Sierra Assembly Technology (USA)
Sierra supports the complete Taconic RF portfolio — RF-35 for broadband RF, TLY for precision low-loss circuits, TLX for moisture-sensitive applications, CER-10 for compact high-Dk designs — and fabricates hybrid stack-ups blending Taconic with FR-4 for cost-optimized multilayer boards.
4. Viasion Technology (China)
A well-established Shenzhen fabricator with a broad Taconic catalog spanning woven-glass PTFE (TLY-3, TLY-5, TLX-8), ceramic-filled laminates (RF-30, RF-35, RF-60, TSM-DS3), and hydrocarbon materials. Viasion is a solid option for small-to-medium volume RF production with good documentation and English-language engineering support.
5. Hitech Circuits / HiL Electronic (China)
Specializes in Taconic RF-35 fabrication, including the RF-35 variant family, and publishes genuinely useful technical guidance on PTFE processing. A good fit for commercial wireless and microwave products below 40 GHz where RF-35’s cost-performance balance shines.
6. iPCB Circuits (China)
Stocks and processes an extensive list of Taconic grades — TLY-3 through TLY-5A, the full TLX range, TLA, TLE-95, TLC, RF-30/RF-35/RF-301, TSM-DS3 and more. Strong material availability makes iPCB useful when your design calls for a less common Taconic grade or thickness.
7. Jarnistech (China)
Offers end-to-end Taconic design, fabrication, and assembly services with particular depth in RF-35 and TLY-5 builds. Their engineering team is comfortable advising on laminate selection, hybrid constructions, and thermal considerations for radar and high-frequency communication systems.
8. Bicheng Enterprise (China)
A high-frequency PCB specialist offering Taconic builds on TLX-9, TLF-35, CER-10 and related grades, with surface finish options including immersion gold, silver, and tin. Good choice for low-layer-count microwave boards at wholesale-friendly pricing.
9. Hemeixin / HighFrequencyPCB (China)
Fabricates across the Taconic range — TLX-8/TLX-9, TLF-35/TLF-35A, TLY, RF-35TC, CER-10 — with flexible copper cladding and thickness options. Particularly useful for low-cost, high-volume commercial microwave and RF applications.
10. Epec Engineered Technologies (USA)
A long-running American manufacturer with global production capability and experience in high-frequency laminates, including Taconic materials, for industrial, defense, and telecom customers. A dependable option when you need program management and supply-chain depth alongside fabrication.
How to Choose the Right Taconic Partner
Before sending out RFQs, check these boxes:
- PTFE processing capability. Pure PTFE laminates like TLY and TLX are soft and require plasma etching or sodium treatment for reliable via plating. Ask how the shop handles hole-wall preparation.
- Impedance control. Request their tolerance guarantees (±5% or better for RF work) and TDR test reports.
- Hybrid stack-up experience. Many 2026 designs pair RF-35 with FR-4 to control cost. Confirm the fab has validated lamination cycles for mixed-material builds.
- Material traceability. Genuine Taconic laminates should come with lot certifications — important for aerospace and defense programs.
- Engineering support. A fab that flags DFM issues before production saves you a respin.
Final Thoughts
Taconic’s TLY, TLX, and RF-35 laminates remain among the best-value high-frequency materials on the market in 2026, but their performance is only as good as the shop that fabricates them. Domestic US fabs like Cirexx and Sierra excel for defense and quick-turn work, while specialists like PCBSync and the established Shenzhen houses deliver excellent cost-performance for commercial RF, antenna, and 5G projects. Match the manufacturer to your volume, certification needs, and frequency band — and always ask for impedance test data before committing to volume.
