High Frequency PCB

ORINEWPCB · FABRICATION TO TURNKEY ASSEMBLY

A high frequency PCB needs a material and stack-up selected for the circuit’s operating band and loss budget. Specify the laminate grade, design dielectric data, copper and impedance requirements together. Flying-probe testing of the bare board does not establish RF insertion loss or assembled radio performance.

Specify the RF requirements that affect fabrication

Frequency alone is not a complete material specification. Dielectric constant and dissipation factor depend on the material, test method and frequency; copper roughness, geometry and dielectric thickness also influence performance. Review the actual circuit constraints instead of assuming that every RF board should use the same laminate.

Keep RF material changes under engineering control

If the specified material is unavailable or affects the requested date, a fast substitution can create a larger engineering problem. Ask for the proposed grade, construction and technical differences before approving it. For a hybrid stack, identify which layers use which materials and the intended electrical references.

1. Provide the fabrication package, operating band and critical RF paths.
2. List controlled-impedance requirements and any coupon or report needs.
3. Identify the approved material and whether an engineering review of alternatives is acceptable.
4. For turnkey assembly, include BOM, placement, connector and shielding instructions.
5. Define RF validation separately from bare-board continuity and short-circuit checks.

Every bare PCB receives flying-probe electrical testing

OrinewPCB flying-probe tests every bare PCB we manufacture, not just a sample. This checks the conductive networks against the electrical test data. Include your netlist where available and identify any required test parameters or records in the RFQ.

An electrical pass does not establish every physical characteristic, controlled impedance, RF performance, thermal reliability or finished-product function. Specify those requirements and any additional evidence separately. This keeps the acceptance scope clear before fabrication begins.

From bare boards to genuine-component turnkey PCBA

Keep the fabrication, BOM purchasing and assembly review connected when you need a finished assembly. Small-to-medium batches and high-mix turnkey PCB assembly are a particular OrinewPCB strength. List quantities and differences for each design or variant so the release is unambiguous.

We supply and use 100% brand-new, original, genuine electronic components for customers’ turnkey assemblies. Our cooperation with manufacturers and distributors helps us seek competitive BOM pricing and practical lead times. Exact MPNs, current availability, permitted sources and delivery dates are checked for your project; alternatives require customer approval.

Nine PCBA quality stages with an agreed test scope

When the order includes assembly, our quality workflow covers nine stages. The applicable inspection plan and evidence are agreed for the actual build:

1. IQC: incoming materials.
2. SPI: solder paste inspection.
3. Online AOI: in-line optical inspection.
4. SMI: first-article inspection.
5. IPQC: in-process quality checks.
6. Offline AOI: post-solder optical inspection.
7. X-ray: hidden joints to the agreed scope.
8. Manual QC: workmanship review.
9. Pre-shipment QA: identification, quantity and packaging.

These are nine quality stages, not nine functional tests. Programming, ICT, functional testing or application-specific validation need an agreed procedure, access or fixtures, and pass/fail criteria. See our factory and quality workflow.

Plan delivery from the complete release package

We work toward the earliest practical delivery for the approved scope. Send the required quantity, design variants and target date, and state whether it means production completion, dispatch or arrival. Materials, engineering questions, assembly preparation and agreed tests all affect the confirmed schedule.

Compare quotations using the same material, revision, sourcing responsibility and acceptance scope. A lower bare-board or placement line item is not automatically a lower complete project cost.

Request a High Frequency PCB review

Send OrinewPCB your files and tell us what you need: bare boards, BOM sourcing or a complete turnkey assembly. Files are optional for an initial discussion.

• Board files, drawing revision and special material or construction requirements
• Quantity per design or variant and repeat-order expectations
• BOM with full MPNs, placement and assembly drawings if assembly is needed
• Inspection, programming, functional-test and documentation requirements
• Target date, delivery destination and any staged shipment needs

High Frequency PCB questions

Is high frequency PCB material always PTFE?

No. RF laminate families use different material systems and offer different electrical and processing properties. Select a specific grade for your requirements rather than treating “high frequency” as one chemistry.

Does a flying-probe pass confirm impedance or insertion loss?

No. Specify impedance measurement and any RF performance verification separately, including the method, applicable nets or coupons and acceptance limits.

Can OrinewPCB quote fabrication and RF assembly together?

Yes. Share the board package, approved BOM, placement data and assembly instructions. Any RF test must have an agreed setup, procedure and limits; it should not be assumed from the assembly quote.
