Key Premise Explanation
The time unit below is working days (excluding Saturdays, Sundays, and public holidays), starting from the date the manufacturer confirms that the Gerber documents and process requirements are correct. We offer two services: "Standard Prototyping" (mainstream choice, cost-effective) and "Expedited Prototyping" (fast prototyping, higher cost, for urgent needs). If special processes are involved (high-precision impedance, blind/buried vias, high-frequency materials, thick copper, stepped grooves, etc.), the time will be increased accordingly.
• Time Calculation Start: The date when the manufacturer confirms the Gerber documents and process requirements are correct
• Working Days Definition: Excluding Saturdays, Sundays, and public holidays
• Expedited Service: Only applicable to boards without complex processes, additional expedited fees required
• Special Processes: Will significantly affect delivery time, please communicate and confirm in advance
PCB Multilayer Board Prototyping Timeline
| PCB Layer Count | Standard Prototyping Time (Working Days) |
Expedited Prototyping Time (Working Days) |
Additional Processing Time for Special Processes (Working Days) |
|---|---|---|---|
| 4 Layer | 2-3 | 1-2 | +1 |
| 6 Layer | 3-4 | 2 | +1 |
| 8 Layer | 4-5 | 2-3 | +1-2 |
| 12+ Layer | 6-8 | 4-5 | +2-3 |
| 18+ Layer | 8-10 | 6-7 | +3 |
| 20+ Layer | 10-12 | 7-8 | +3-4 |
| 44+ Layer | 18-22 | 12-15 | +4-5 (DFM review required 1-2 days in advance) |
Additional Notes
44+ Layer Classification: Ultra-high multilayer boards (commonly used in servers and high-end communication equipment). A manufacturability (DFM) review must be conducted before prototyping. The timeframes in the table above already include the basic review period.
Time Example: A 4-layer board can be delivered in as fast as 48 hours (1 working day), and a 6-layer board in 72 hours (without special processes).
Comparison with Small/Medium Manufacturers: Small and medium manufacturers typically take 1-3 working days longer than the times listed above, and most do not have the capacity to undertake 44+ layer boards.
Impact of Special Processes: Special processes such as high-frequency/high-speed materials, HDI, microvia technology, etc., will significantly increase production time. It is recommended to communicate with engineers in advance to confirm specific timelines.
