Why High Frequency PCB Turnkey Is Different
Most turnkey PCB factories in China handle FR4 well — but Rogers and PTFE materials require process knowledge that generic PCBA factories often don’t have. The two most common failures are: using a standard SAC305 reflow profile on PTFE substrates (which causes dimensional shifts at peak temperatures above 260°C), and outsourcing PTFE fabrication to a third party where plasma activation timing cannot be controlled. Riching PCB fabricates and assembles in the same facility — material knowledge from the PCB process is applied directly to the SMT process.
| Generic Turnkey PCB China | Riching PCB Turnkey | |
|---|---|---|
| PCB material range | 🚩 FR4 and basic laminates | ✅ Rogers, PTFE, Taconic, F4B + FR4 — all in stock |
| High frequency PCB | 🚩 Outsourced or declined | ✅ In-house — plasma activation, TDR every lot |
| PTFE SMT reflow profile | 🚩 Standard SAC305 — risky for PTFE | ✅ Modified profile per material, confirmed before SMT |
| Impedance control | 🚩 ±10% or unspecified | ✅ ±10% standard, ±5% TDR available |
| BGA / fine-pitch | 🚩 Basic 0.8mm BGA only | ✅ Down to 0.4mm BGA, X-Ray inspection |
| MOQ | 🚩 50–100 board minimum typical | ✅ No MOQ — from 1 board |
| Lead time (PTFE turnkey) | 🚩 6–8 weeks (procurement + fab + SMT) | ✅ 15–20 working days (material in stock) |
Turnkey Applications

| EW receiver module PCBA | RT5880 | 15–20 working days |
| 5G mmWave prototype PCBA | RO3003 / RO4350B | 10–15 working days |
| RF front-end module (general) | RO4350B / FR4 | 10–15 working days |
| Mixed FR4 + Rogers multilayer PCBA | Hybrid stackup | 15–20 working days |
