What to specify for HyRelex TF-260 / TF-290
Taconic HyRelex TF-260 / TF-290 is covered here as a historical or specialty material designation. The archive lists nominal Dk 2.60 and 2.90. A flexible substrate designation is not a validated bend-cycle rating.
| Field | Specification context |
|---|---|
| Material identity | HyRelex TF-260 / TF-290 |
| Reference Dk | Exact grade / construction data required |
| Reference Df | Not assigned; obtain a value for the chosen construction |
| Test context | Archived specialty-material listing |
| Thermal conductivity | Confirm in the applicable supplier data sheet |
| Supply status | Confirm current grade, thickness, foil and order quantity; no stock promise |
Do not miss: The archive lists nominal Dk 2.60 and 2.90. A flexible substrate designation is not a validated bend-cycle rating.
Historical provenance: the archived Taconic Laminate Material Guide used for this table. The historical values and stated test conditions are retained for identification; they are not current purchase limits. Verify the ordered grade against its original datasheet and certificate. For current product families and supplier document requests, consult the . That current guide does not independently verify every historical value above.
RF film, flexible construction and motion
A thin dielectric film is one component of a flexible RF construction. Copper thickness, adhesive or bonding layers, strain concentration and shielding influence both electrical behavior and mechanical life. A bend requirement should state radius, direction, number of cycles and operating environment; thinness alone is not a reliability qualification.
- Define static fold versus repeated motion
- Specify copper type, neutral axis and strain limits
- Review connector transitions and shielding
Taconic PCB Design Workbench
The RF tool uses an editable model Dk; the preset is a supplier reference at its stated method and frequency. It is not a universal design Dk. Blank parameters stay blank until you provide a value. Geometry calculations do not approve a fabrication tolerance.
For microstrip, h is the dielectric separation to the reference plane; for symmetric stripline it is the total plane spacing. Propagation follows 位g = c/(f鈭毼礶ff). Thermal screening uses R = h/(kA). Read the selected model鈥檚 exclusions beside the result.
For more geometries and fabrication tolerance context, use the PCB impedance calculator and design guide.
From material callout to fabricated PCB
Material release
Name HyRelex TF-260 / TF-290, the supplier revision, thickness and foil. Separate approved substitutions from suggestions awaiting approval.
CAM and stackup
Review layer references, panelization, copper balance, minimum features and finished geometry. Define static fold versus repeated motion.
Process definition
Use the applicable laminate and bonding guides. Agree drilling, hole-wall treatment and lamination details for this construction; do not assume a universal FR-4 recipe.
Patterning and final build
Control conductor geometry, hole quality, mask openings and finish on exposed RF areas. Include special edges, cavities or connectors in the release.
Inspection and acceptance
Define dimensional, netlist and impedance checks. RF loss or phase measurements need a separate coupon/fixture, frequency range and acceptance limit.
Review the manufacturing capability tables for general process limits and quality documentation and acceptance planning for supplier review. A listed material property is not a 吃瓜tv test report.
HyRelex TF-260 / TF-290 PCB cost & quotation brief
A quote for HyRelex TF-260 / TF-290 depends on the approved material construction, purchased sheet utilization, quantity, layer count, drilling/lamination work, finish and inspection scope. There is no defensible fixed 鈥淭aconic multiplier鈥� across these products. For older designations, sourcing confirmation may be the first cost decision.
Taconic PCB Cost & Quotation Brief
Use the brief without prices, or enter your own setup and fabrication-area allowances to explore a simple two-layer planning range. The tool does not contain verified current supplier rates. Hybrid, multilayer, bonding-film and RF-qualified builds are routed to engineering quotation.
| Cost question | Information to provide |
|---|---|
| Material | Exact code, thickness, foil, substitutions allowed or prohibited |
| Fabrication | Gerber/ODB++, drill data, stackup, copper, outline and special features |
| Acceptance | Net classes, impedance target/tolerance and any RF test fixture |
| Order | Quantity, requested delivery date, repeat-build needs and assembly scope |
HyRelex TF-260 / TF-290 questions before ordering
What does the HyRelex TF-260 / TF-290 material name guarantee?
It identifies a material or family to resolve in the supplier documentation. The exact code, thickness, foil and data-sheet revision still need to be specified. It does not guarantee 吃瓜tv stock, lead time or an application qualification.
Which Dk should I use in my RF model?
Archived specialty-material listing. Use a model Dk appropriate to your geometry and frequency. A process test value is useful reference data but is not automatically the effective permittivity of a microstrip.
Can I replace HyRelex TF-260 / TF-290 with another Taconic or Rogers grade?
The archive lists nominal Dk 2.60 and 2.90. A flexible substrate designation is not a validated bend-cycle rating. Compare the complete electrical, mechanical and processing requirements, then approve the alternate explicitly.
What design detail deserves the first review?
Define static fold versus repeated motion. Identify whether the film is the signal dielectric or a bonding material.
Does a netlist test verify RF performance?
No. Netlist testing checks connectivity. RF performance requires defined measurement structures, frequency range, reference planes and limits. State the required measurement in the RFQ.
How do I obtain a usable quotation?
Send the fabrication files, drill data, stackup, exact material code, quantity and acceptance requirements. Include your requested date; the delivery commitment depends on sourcing and process review.
