What to specify for FEP / HT-1.5 / TPN / TacBond
Taconic FEP / HT-1.5 / TPN / TacBond is covered here as a historical or specialty material designation. Thermoplastic films and thermoset prepregs do not share a press recipe. These trade names must be resolved to a supplier product.
| Field | Specification context |
|---|---|
| Material identity | FEP / HT-1.5 / TPN / TacBond |
| Reference Dk | Exact grade / construction data required |
| Reference Df | Not assigned; obtain a value for the chosen construction |
| Test context | Archived bonding-film family descriptions |
| 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: Thermoplastic films and thermoset prepregs do not share a press recipe. These trade names must be resolved to a supplier product.
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.
Bonding layers belong in the electrical stackup
A bonding film or prepreg fills copper relief and joins adjacent cores. Its thickness after pressing can differ from the supplied material thickness. Resin content, copper density, ply count and the press cycle affect the result. Specify these together before using a stripline model or comparing multilayer costs.
- Identify flow, cure or melt behavior
- Agree bonding temperature and core compatibility
- Include thermal exposure of the complete build
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 FEP / HT-1.5 / TPN / TacBond, 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. Identify flow, cure or melt behavior.
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.
FEP / HT-1.5 / TPN / TacBond PCB cost & quotation brief
A quote for FEP / HT-1.5 / TPN / TacBond 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 |
FEP / HT-1.5 / TPN / TacBond questions before ordering
What does the FEP / HT-1.5 / TPN / TacBond 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 bonding-film family descriptions. 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 FEP / HT-1.5 / TPN / TacBond with another Taconic or Rogers grade?
Thermoplastic films and thermoset prepregs do not share a press recipe. These trade names must be resolved to a supplier product. Compare the complete electrical, mechanical and processing requirements, then approve the alternate explicitly.
What design detail deserves the first review?
Identify flow, cure or melt behavior. Use the exact construction code and pressed thickness.
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.
