PTFE
Circuit boards on PTFE-based materials for demanding RF applications.
PTFE with ShinePCB
PTFE materials offer excellent electrical properties but need specific processing. We review processing requirements, compare options with your targets and confirm each project individually.
- PTFE material type
- Hole preparation and plating
- Hybrid constructions
- Finish selection

Source: ShinePCB capability workbook, material sheet. Dk, Df and Tg are typical supplier datasheet values (test frequency shown where the source lists it). They describe the laminate, not the finished board. Grades are available on request and confirmed with availability during engineering review. "—" means no value is listed in the source.
Typical applications
Microwave circuits
Radar and sensing
Satellite communication
From prototype to production
Every order follows the same controlled sequence. Prototype and production requirements are reviewed separately.
File review
Gerber or ODB++, drill data, drawing and quantities are checked for completeness.
Engineering questions
Open points on manufacturability, materials or special processes are sent before quotation.
Stack-up and material
Construction, laminate and finish are confirmed with you and written into the order.
Fabrication
The order is released to the facility whose process and qualification fit the requirements.
Inspection and test
Inspection and electrical test follow the methods agreed for your order.
Packing and delivery
Boards are packed and shipped under the confirmed delivery terms.
What to send for a PCB review
Start with the details you have — engineering will request anything else needed for the review.
Files and details for a PCB review
- Gerber (RS-274X) or ODB++ data with drill files
- Fabrication drawing with material, thickness and finish
- Stack-up and impedance targets, if any
- Quantity for prototype and for production
- Special requirements such as IPC class, testing or packaging
Technical files stay private
Customer Gerber, BOM and design data are managed under an ISO/IEC 27001 information security system and shared only within your project.
PTFE FAQs
Is PTFE harder to process?
It needs specific processing steps, which are reviewed during engineering review.
Can PTFE be combined with FR-4?
Hybrid constructions are reviewed per project.
