Arlon AD260A PCB — Historical material designation

AD260A: historical material designation. Listed in an archived manufacturer microwave-materials guide.

Historical reference. Current production, availability and replacement status have not been confirmed. This page does not offer stock or claim a drop-in replacement.

Where AD260A fits in your design

Retain the exact grade on the original drawing. Obtain current manufacturer or distributor confirmation before ordering, substituting or changing the RF layout. 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.

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 AD260A

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.
Review processing compatibility. Review hole preparation, metallization, dimensional movement and the complete thermal history with the selected construction.
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 AD260A 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 AD260A 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 AD260A

Can another grade replace AD260A?

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 AD260A available for immediate manufacture?

Current supply has not been established for this historical designation. Send the exact requirement through the inquiry form for a sourcing review before committing to a schedule.
