Qingjian Electronic multilayer capabilities
We prototype multilayer boards across a wide range of technologies and use cases — from 4-layer controlled-impedance boards for high-speed equipment to 12-layer HDI stackups for compact products.
Layer count: 4 to 12 layers (typical quick-turn: 4–6 layers)
Minimum trace/space: down to 3–4 mil (process-dependent)
Via support: through-hole, blind/buried vias, microvias & laser vias
Via-in-pad: copper fill & planarization for BGA pads
Copper weight: 0.5 oz – heavy copper up to 6 oz (per layer options)
Materials: FR-4 standard, high-TG, Rogers and other HF substrates
Surface finishes: ENIG, HASL, OSP, immersion silver
Board size / thickness: up to 450mm × 450mm; thickness 0.4–3.2mm
Typical lead times & quick-turn tiers
Use the matrix below to estimate turnaround. Final lead time is confirmed after Gerber/BOM review and depends on parts availability and testing requirements.
| Board Type | Qty | Quick-turn (typical) | Standard |
|---|---|---|---|
| 4-layer, standard FR-4 | 1–10 | 3–5 business days | 7–12 business days |
| 6-layer, controlled impedance | 1–20 | 5–8 business days | 10–15 business days |
| 8-layer HDI with microvias | 1–50 | 7–12 business days | 12–20 business days |
| 10–12 layer rigid-flex / heavy copper | 1–50 | 10–15 business days | 15–25 business days |
Note: These are representative estimates. If you need guaranteed SLA lead times for a program, request a locked schedule during quoting.
How we manufacture multilayer prototypes
Our multilayer process follows strict controls to ensure stackup accuracy and yield:
Stackup design & prep: engineer-verified stackups and impedance targets with test coupons.
Lamination: controlled lamination cycles for multilayer bonding and reliability.
Drilling & plating: mechanical & laser drilling for microvias; uniform plating to spec.
Imaging & etch: precise inner/outer layer imaging and etching control.
Surface finish & routing: finish selection, routing and edge profiling.
Assembly & test: SMT assembly, AOI, 3D X-ray for BGAs, ICT/flying-probe and functional testing.
Design for Manufacturability (DFM) for multilayer boards
Following DFM best practices reduces rework and shortens prototype lead time. Download our free DFM checklist and stackup templates to accelerate quoting and production.
Top DFM tips
Provide a complete Gerber set (or ODB++/IPC2581) and a BOM with manufacturer part numbers.
Include a clear stackup, controlled impedance targets and a PCB fabrication drawing.
Avoid excessive via-in-pad unless using filled & planarized processes; declare BGAs and critical components.
Group similar variants to share tooling and reduce per-board cost.
High-speed design & controlled impedance
We provide impedance modeling, coupon measurement (TDR) and validated stackups for high-speed designs. Typical services include target impedance calculation, test coupon fabrication and verification reports to ensure signal integrity for DDR, USB, RF and high-speed SerDes interfaces.
Assembly & quality assurance
Our multilayer assembly & test capabilities include:
SMT placement down to 01005 and 0201 components
Fine-pitch BGA & microBGA handling, reflow profile optimization
AOI (2D/3D), 3D X-ray inspection, ICT and flying-probe testing
Functional test fixture development and FAI reporting with traceability
Turnkey services & component sourcing
We offer end-to-end turnkey prototyping: BOM sourcing, procurement of long-lead items, authorized part substitution, kitting and global DDP shipping. For startup projects we provide sourcing recommendations to meet cost and lead-time targets.
From prototype to NPI & low-volume production
We help customers scale prototypes into pilot runs by optimizing panelization, test coverage and cost-of-goods. Recommendations include pilot run sizing, yield analysis and production transfer plans to minimize surprises at scale.
Representative case studies
Challenge: tight impedance tolerance and small form factor. Solution: validated stackup, TDR verification and 10-pc quick-turn prototype delivered in 7 days. Result: passed EMC pre-tests and reduced rework by 30%.
Challenge: dense BGA layout. Solution: microvia HDI process with via-in-pad fill and 3D X-ray inspection. Result: pilot run of 50 pcs delivered with 98.5% first-pass yield.

FAQ — Multilayer PCB prototyping services
Q: What layer counts do you prototype?
A: We prototype 4–12 layer boards. Quick-turn tiers are fastest for 4–6 layers; 8+ layers typically require longer lamination cycles.
Q: How can I speed up lead time for a multilayer prototype?
A: Provide a complete Gerber/BOM package, choose standard materials, pre-approve substitute parts and request our free DFM review at submission.
Q: Do you measure impedance for multilayer PCBs?
A: Yes — we provide impedance coupon fabrication and TDR verification as part of controlled-impedance services.
