Kapton & FR-4 Antenna Fabrication

I’m ready to move my microstrip patch antenna design into production and need a shop that can build prototypes on two distinct substrates:

• Copper-clad polyimide (Kapton) – 0.127 mm, kept fully flexible after etching
• FR-4 – 0.2 mm, standard rigid board

Because I selected Both in the substrate options, I need each version produced to the same RF-grade accuracy. Please let me know:

1. Whether your line can handle flexible Kapton as confidently as FR-4, including any special tooling or process controls you employ.
2. Itemised pricing for low-volume runs on each substrate.
3. Typical lead time from Gerber release to outbound shipment.
4. A short overview of your fabrication and inspection facilities (LDI, controlled-depth etch, AOI, impedance control, peel testing, etc.).

Acceptance criteria
• Finished boards match my Gerber and drill files within published tolerances.
• Copper adhesion on Kapton passes a standard peel test.
• All vias plated, no shorts, clean edges, and boards arrive safely packaged.

If you have sample images or brief case studies of previous Kapton jobs, I’d love to see them. I’m ready to send design files as soon as I confirm you can meet the above points. Looking forward to your reply with cost, schedule, and any questions you need answered.
