DESIGN / VERIFY / MANUFACTURE / WITH CONFIDENCE
Start with the right questions.
BETTER BOARDS STARTWITH CLEARER DECISIONS
A well-planned stackup makes all the difference.
Answering a few questions early helps you create a clearer path from electrical intent to fabrication.
Where are your return paths?
Plan continuous reference planes and check how return current crosses layer transitions.
What will each layer do?
Assign signal and plane functions to match routing density and power needs.
Which materials fit your needs?
Confirm dielectric and copper construction before finalizing controlled traces.
Choose properties, not just a material name.
A laminate choice needs to match electrical, thermal and mechanical requirements.
What temperatures will the board see?
Consider assembly reflow and the operating environment as separate conditions.
Which electrical properties matter?
Use material data at the relevant frequency and test method.
Can the construction be sourced?
Confirm available cores and prepregs before fixing your dielectric dimensions.
Start with the reference plane.
Impedance is a result of the complete transmission-line geometry, not the layer count.
What is the target and tolerance?
State each controlled net class and the required measurement conditions.
Which geometry is being routed?
Record trace width, spacing, dielectric height and copper thickness.
How will it be verified?
Agree any coupon requirements and the reporting needed for acceptance.
Make the fabrication package unambiguous.
A complete handoff reduces questions that can delay a build.
Are the layer files clearly named?
Supply a readable copper layer map, outline and plated / non-plated drills.
What must not be substituted?
Identify material, finish and construction constraints in the fabrication notes.
What defines an acceptable board?
Specify dimensional, electrical and documentation requirements before release.

Manufacturing starts
with the right details.
Six copper layers make room for routing and reference planes. A manufacturable board also needs an agreed material, dielectric construction, hole structure and acceptance criteria.
Explore manufacturing capabilities| Layer construction | Six conductive layers with a clearly identified layer order |
|---|---|
| Base material | Laminate family, Tg and electrical requirements |
| Board thickness | Finished thickness and mechanical tolerance |
| Copper | Starting and finished copper requirements by layer |
| Impedance | Target, tolerance, trace geometry and reference layers |
| Finish & holes | Surface finish, plated / non-plated drill data and via requirements |
| Delivery | Quantity, prototype or production intent, and required date |
Material availability, geometry and delivery are reviewed together for each project.
A CLEAR PATH TO PRODUCTION
From your files to an agreed build.
- 01
Share the requirements
Send Gerber files, drill data, quantity and the specification you need.
- 02
Review the construction
Resolve layer order, materials, impedance and fabrication questions.
- 03
Confirm the details
Agree the technical scope, acceptance requirements and delivery plan.
- 04
Prepare for production
Use the approved fabrication package as the controlled build reference.
BALANCE PERFORMANCE & PRACTICALITY
Every decision
has a trade-off.
A stackup is more than a layer count. Compare electrical, mechanical and procurement requirements before committing to a build.
Discuss your requirementsMaterials & thermal demands
Match laminate properties to operating conditions, assembly temperatures and electrical needs.
Surface finish & assembly
Consider pad flatness, storage, solderability and the assembly process.
Lead time & project planning
Material availability, review cycles, special processes and shipping all affect the schedule.
Quality & acceptance
Specify the inspection evidence, acceptance criteria and traceability the application needs.

Before you
send your files.
Start with the decisions that make a quotation more useful.
What is a 6 layer pcb?
It is a circuit board with six conductive copper layers separated by dielectric material. Those layers can carry signals, power or reference planes; their functions depend on the design.
Is there a single best six-layer stackup?
No. Choose the layer arrangement around return paths, routing density, power distribution and the manufacturer’s achievable construction. Confirm dielectric thicknesses before routing impedance-controlled signals.
What files are needed for a quotation?
A complete Gerber set, drill files, an outline and fabrication notes provide a useful starting point. Include quantity, material, finish, impedance requirements and the required date. Assembly inquiries also need a BOM and placement data.
Can I upload RAR files?
RAR is supported alongside ZIP, 7Z, documents, images and common PCB engineering files. Check the enabled formats on the inquiry form. You can attach up to five files, 10 MiB per file and 25 MiB in total.
Can you confirm a lead time before reviewing the files?
A firm plan depends on material availability, construction, special processing and order quantity. Share your target date so those factors can be reviewed together.
Does a six-layer board automatically improve signal integrity?
No. Layer count alone does not ensure performance. Continuous reference paths, geometry, placement and appropriate routing rules remain essential.
