Arlon TC350 Plus PCB — RF laminate

TC350 Plus: rf laminate. Nominal Dk 3.50; Z-axis thermal conductivity 1.24 W/mK.

Manufacturer-listed material. Exact construction, availability and lead time require project-specific confirmation.

Where TC350 Plus fits in your design

Preserve the Plus designation and verify the direction of thermal property data. Define what the material must achieve in the finished board before selecting thickness, copper and surface finish. The material name alone does not define a manufacturable construction.

Material identification and technical reference

Typical values are reference information, not acceptance limits. Match the test method, frequency, conditioning, thickness and document revision before comparing data. Missing figures are intentionally not estimated.

Fabrication review for TC350 Plus

  1. Identify the construction. Provide the drawing revision, exact grade, layer sequence, dielectric thicknesses and copper requirements. Mark whether substitutions are prohibited or require written approval.
  2. Review processing compatibility. Review hole preparation, metallization, dimensional movement and the complete thermal history with the selected construction.
  3. Set measurable acceptance criteria. Identify impedance coupons, dimensional checks, electrical testing and cross-sections that are required for this project. Do not assume a catalogue material specification covers finished-board reliability.

What changes the cost?

A useful TC350 Plus quotation starts with quantity, panel use and the exact material construction. Special thicknesses, foil requirements, additional lamination cycles and project-specific inspection can change sourcing and processing costs. A generic multiplier against FR-4 cannot establish the price of your build. Use the design and cost planning tools to organize the requirements, then request a written project quotation.

Prepare your TC350 Plus inquiry

Upload your fabrication drawing, stack-up and Gerber or ODB++ package through our project inquiry form. Include board size, quantity, finish, delivery target and the exact material designation. If this is an existing design, attach the approved material specification and identify any substitution restrictions.

Questions about TC350 Plus

Can another grade replace TC350 Plus?

Only after design and procurement approval. Compare material role, electrical properties, expansion, bond system and the qualified process. A similar dielectric constant or product name is not sufficient evidence.

Is TC350 Plus available for immediate manufacture?

Availability depends on the required thickness, foil and order quantity. Send the exact requirement through the inquiry form for a sourcing review before committing to a schedule.
