Prototype and Low-Volume Bare PCB Manufacturing

JetH Pro PCB Fab builds the bare PCB you need to validate now—and keeps the approved construction ready for the next build.

JetH Pro PCB Fab routes each order by PCB construction and validation risk—not by piece count alone.

ENGINEERING RELEASE GATE

PCB Prototype Engineering Review Before Fabrication

A fast prototype is useful only when the manufactured board still represents the intended design.

FILES Gerber / ODB++ · NC drill · Drawing · Revision
CONSTRUCTION   Layers · Thickness · Copper · Material · Vias
DFM Trace / space · Drills · Annular rings · Edge clearance
IMPEDANCE Stack-up · Dielectric · Trace geometry · Tolerance
APPROVAL CAM changes · Conflicts · Material alternatives
JetH Pro PCB Fab prototype PCB engineering and fabrication review
We do not release an unclear PCB build.

Production timing is confirmed after the files are complete, technical questions are closed and the order is released.

FABRICATION EVIDENCE

Prototype PCB Inspection and Quality Verification

“Quality PCB” is not an acceptance method. The inspection route must match the board and the released requirement.

AOI inspection for prototype and low-volume bare PCBs
AOI Layer pattern · Registration
PCB microsection inspection for hole copper and internal structure
MICROSECTION Hole copper · Internal structure
Bare PCB electrical test and final quality verification
ELECTRICAL TEST Open / short · Final acceptance
STANDARD AOI · Dimensions · Electrical test
IMPEDANCE Coupon · TDR · Report
STRUCTURE Microsection · Hole copper
DOCUMENTS CoC · Material · FAI
Which tests and reports must be specified before quotation? +

Identify required impedance reports, microsections, hole-copper measurements, material certificates, CoC, first-article reports, solderability testing or ionic contamination testing before the order is released.

PROCESS WINDOW · REPEATABILITY

Bare PCB Capabilities for Prototype and Low-Volume Production

Layer count 1–40 layers (<5 m²); 1–20 layers (≥5 m²)
Board thickness 0.20–7.00 mm, subject to construction
Finished copper Up to 10 oz internal / 20 oz external for applicable orders
Trace / spacing 3/3 mil with applicable copper construction
Mechanical hole 0.10–6.20 mm finished diameter
Laser microvia 0.10–0.15 mm; applicable filled vias 4–5 mil
Special structures HDI 3+n+3 · blind/buried vias · via-in-pad · back drilling

Final feasibility is confirmed from the complete construction. Maximum limits may not be combinable.

JetH Pro PCB Fab carries the approved requirements forward instead of treating the next order as an unrelated build.

Additional materials, surface finishes and manufacturing options +

Materials: FR-4, high-Tg FR-4, Rogers, Taconic, Arlon, Nelco, PTFE and hybrid constructions.

Finishes: ENIG, HASL, OSP, ENEPIG, hard gold, soft gold, immersion silver and immersion tin.

PROJECT OPTIONS · QUOTATION

Select the PCB Information Relevant to Your Project

› PCB Types & Project Fit
› Materials & Stack-Ups

Standard and custom constructions, specified laminate grades and material substitution restrictions.

› Surface Finishes

State the required finish, gold thickness and connector condition when they affect function or acceptance.

› Testing & Documentation

Specify impedance reports, microsections, certificates, FAI records and other required deliverables.

› Files for Quotation

Gerber or ODB++, NC drill, dimensions, layers, quantity, thickness, copper, material, finish and delivery date.
