PTFE Material Stock — Every Major Grade Available
PTFE PCB materials cost USD 500–1,500/m² depending on grade. Most factories treat them as special-order items. Riching PCB stocks every major PTFE grade as standard inventory — from RO3003 0.127mm for 77GHz radar to RO3010 Dk 10.2 for compact filter designs.

The Plasma Activation Difference
Plasma activation must be performed in-house and within 2 hours of copper plating. After that, the activated PTFE surface begins to deactivate — copper deposits with zero mechanical adhesion and separates from the hole wall after 3–5 thermal cycles. Boards pass initial testing and fail in the field.
Most factories that claim PTFE capability outsource plasma activation to a third-party facility. By the time boards are transported and plating begins, the window has closed. Riching PCB operates an in-house RF plasma chamber — activation and plating occur in the same facility, same production shift.
| Process Step | Riching PCB | Without Genuine PTFE Capability |
|---|---|---|
| Plasma activation | ✅ In-house RF plasma — same shift | 🚩 Outsourced: surface deactivates in transit |
| Activation to plating | ✅ 1–2 hours, enforced | 🚩 4–24+ hours: copper adhesion fails |
| PTFE drill speed | ✅ 40,000–60,000 RPM | 🚩 FR4 speed: PTFE smear blocks plasma |
| Lamination cycles | ✅ Maximum 2 — enforced | 🚩 No limit: Dk shifts, delamination risk |
| Material stock | ✅ RO3003, RT5880, RO3006 on shelf | 🚩 3–4 week procurement per order |
| RO3003 lead time | ✅ 7–10 working days | 🚩 5–7 days = FR4 process on PTFE |
| TDR verification | ✅ Every production lot | 🚩 On request only or not at all |
