Rigid, HDI & rigid-flex PCB fabrication — 2 to 36 layers

Quint Tech fabricates rigid, HDI, flex and rigid-flex PCBs in its own 12,000 m² Shenzhen plant — from fast-turn prototypes to mid-volume production. Every Gerber package receives a DFM (design-for-manufacturing) review before tooling, and boards are inspected to IPC standards before shipment.

Capabilities at a glance

Rigid boards	2–36 layers (samples); prototype to mid-volume production
Rigid-flex boards	Up to 18 layers (30 layers planned)
Minimum line width / space	1.5 mil (HDI)
Minimum drilled via	0.075 mm mechanical; 0.05 mm blind via
Maximum aspect ratio	16:1
Controlled impedance	±5%
High-frequency materials	Rogers 4350B, PTFE and ceramic laminates
Heavy copper	Up to 5 oz inner/outer layers
Surface finishes	ENIG, HASL, OSP, immersion tin / silver, NiPdAu (ENEPIG)
Panel capability	Oversized panels to 555×545 mm (e.g. medical MRI boards)
Special processes	Half-hole (castellated), back-drilling, blind/buried vias, heavy gold plating

Prototype runs and small batches

Two-layer sample boards ship in as few as 5 working days, and complex 36-layer builds in around 9 days. There is no high-MOQ gate: engineering samples, pilot runs and production lots run on the same lines, so what you validate in prototyping is what you get in volume.

HDI, controlled impedance and high-frequency boards

For RF, 5G and high-speed digital designs we process Rogers 4350B, PTFE and ceramic laminates with ±5% controlled impedance, lines down to 1.5 mil and mechanical vias down to 0.075 mm. Blind and buried vias, back-drilling and 0.05 mm blind microvias are standard in-house processes.

Rigid-flex and heavy copper

Rigid-flex builds up to 18 layers (30-layer capability planned) suit compact, high-reliability enclosures; heavy copper boards to 5 oz support power conversion, motor drives and energy systems. All common surface finishes are available, including ENIG and NiPdAu (ENEPIG).

Typical lead times

Board type	2L	4L	6L	8L	>10L
Rigid PCB — samples (working days)	5	6	7	8	9
Rigid PCB — production	10	12	14	15	18
Rigid-flex — samples	10	12	14	14	16
Rigid-flex — production	14	14	16	18	20

Working days ex-factory. Special processes (half-hole, thick copper, back-drilling) add 1–3 days. SMT assembly samples typically ship in 3–5 days; volume PCBA in 20–30 days.
