PCB Design Guides and Resources
Use these resources to make a PCB inquiry specific enough for engineering review.
Find an exact material
The Arlon PCB material library separates current manufacturer listings from historical designations. Every model has a dedicated reference page. Check the source revision and ordering construction before releasing a design.
Prepare the manufacturing package
The manufacturing guide walks through material, multilayer construction, hole preparation, surface finish and inspection. Keep revisions consistent across artwork, drawings and stack-up files.
Explore finish and cost inputs
Open the engineering workbench to convert gold-thickness units, review cost drivers and download a fabrication handoff checklist. These tools organize requirements; they do not approve a design or produce a binding quotation.
Connect application to construction
Review the application guide for the environmental and documentation questions that shape material choice. Distinguish supplier data from finished-board test results.
Working with a historical designation
Start with the original drawing, bill of materials and last approved material specification. Obtain written confirmation of current sourcing before assuming a similar model is equivalent. Design changes may require electrical, mechanical and reliability requalification.

Avoid PCB fit and impedance errors by separating core thickness, pressed dielectric spacing and total finished thickness with a worked tolerance budget.
Polyimide versus epoxy for a thermally cycled assembly
Compare polyimide and epoxy PCB candidates using the actual thermal cycle, interconnect geometry and validation evidence, rather than Tg alone.
