Turnkey Lead Time
| Service | PCB Fabrication | SMT Assembly | Total Turnkey |
|---|---|---|---|
| FR4 / RO4350B + SMT | 5–7 days | 5–7 days | 10–15 working days |
| RO3003 / RT5880 / PTFE + SMT | 7–10 days | 5–7 days | 15–20 working days |
| SMT only (boards supplied) | — | 5–7 days | 5–7 working days |
Lead time is counted from DFM approval. PCB fabrication and SMT preparation (stencil, programming) run in parallel where possible to minimize total turnaround.
Turnkey Process
- Send: Gerber zip + NC drill + stackup drawing + BOM + Pick & Place (Centroid) file
- DFM review: PCB manufacturability + BOM component check + assembly feasibility — 4–8 hours
- PCB fabrication: Rogers / PTFE / FR4 — 5–10 days depending on material
- SMT assembly: paste printing, component placement, reflow — 5–7 days
- Inspection: AOI on every board, X-Ray for BGA and hidden joints
- DHL Express delivery: 3–5 days to USA / Europe / Israel
SMT Assembly Capability

| IPC standard | IPC-A-610 Class 2 | Class 3 on request |
| MOQ | No minimum | From 1 board |
Solder Profile for Rogers and PTFE Materials
The most common assembly error with high frequency PCB is applying a standard SAC305 lead-free reflow profile (peak 255–260°C) to PTFE substrates. Rogers RO3003 and RT5880 are PTFE-based — PTFE begins to soften above 260°C and can cause dimensional changes that shift impedance and antenna resonant frequency. Riching PCB runs modified reflow profiles for all PTFE PCB assembly, confirmed per material grade before SMT starts.
| PCB Material | Solder Profile Consideration | Riching PCB Approach |
|---|---|---|
| Rogers RO4350B / RO4003C | Tg 280°C — compatible with standard SAC305 reflow | Standard lead-free profile, no modification needed |
| Rogers RO3003 / RT5880 (PTFE) | PTFE softens above 260°C — peak temp must be controlled | Modified reflow profile, max peak 245°C, confirmed before SMT |
| Taconic / F4B | Similar to PTFE — Tg and softening point verified per grade | Profile confirmed per material datasheet before SMT |
| FR4 high-Tg | Tg 170°C+ — compatible with lead-free | Standard lead-free profile |
Why One Supplier for Fabrication and Assembly
- No handoff risk — the factory that built the board assembles it, so material properties and pad tolerances are already understood
- Faster DFM — PCB and assembly DFM reviewed together, not sequentially
- PTFE process continuity — plasma activation, lamination cycle count and reflow profile managed as a single process chain, not split between two factories
- Single point of contact — one WhatsApp conversation from file submission to delivery
- No MOQ — prototype assembly from 1 board, same as PCB-only
Files Required for Turnkey Quote
- Gerber files (RS-274X) + NC drill
- Stackup drawing — material grade, dielectric thickness, copper weight
- BOM — part numbers, manufacturer, designator, quantity
- Pick & Place / Centroid file — XY coordinates, rotation, top/bottom side
- Any special notes: IPC Class, specific solder profile requirements, conformal coating
