ORINEWPCB · FABRICATION TO TURNKEY ASSEMBLY
A halogen-free PCB request should identify the required material definition, laminate grade and supporting documentation. A bare-board material claim does not automatically establish the status of every component or the complete assembled product. Define the scope before comparing supplier quotations.
Make the halogen-free requirement verifiable
Halogen-free, RoHS compliance and flame-retardancy classification describe different requirements. They should not be used as substitutes for one another. When a customer or product specification calls for a halogen-free construction, send the applicable requirement and ask which materials and records must be covered.

| Decision | Send or confirm | Why it matters |
|---|---|---|
| Applicable definition | The customer specification, threshold basis or referenced requirement and revision. | Avoid treating a general “green PCB” description as an acceptance criterion. |
| Laminate and prepreg | Approved manufacturer/grade and any allowed equivalent. | Confirm the complete stack construction rather than only one material name. |
| Other board materials | Scope for solder mask, legend, coverlay or other relevant materials. | A laminate declaration alone may not answer the full board requirement. |
| Documentation | Required declarations, material identification and delivery documentation. | Agree the evidence and its scope before production. |
| Assembled product | Whether the requirement extends to components, connectors and other assembly materials. | Whole-product claims require a broader review than bare-board fabrication. |
Balance material requirements with thermal and electrical performance
Choosing a halogen-free grade does not by itself define Tg, dielectric behavior, moisture performance or suitability for an assembly process. Keep those requirements in the same fabrication drawing and review any alternative against the complete specification. Do not approve a substitution solely because it carries a halogen-free description.
- Send the relevant product/customer requirement and its material scope.
- Specify the approved laminate and the properties that must remain unchanged.
- Identify the declarations and traceability information needed with the order.
- For turnkey PCBA, flag component-level environmental documentation requirements.
- Confirm any material change before purchasing or releasing the next revision.
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.
Bare PCB supply
Release the fabrication data, quantity, acceptance scope and delivery needs.
BOM sourcing
Send full manufacturer part numbers, quantities, approved alternatives and documentation needs.
One-stop assembly

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:
- IQC: incoming materials.
- SPI: solder paste inspection.
- Online AOI: in-line optical inspection.
- SMI: first-article inspection.
- IPQC: in-process quality checks.
- Offline AOI: post-solder optical inspection.
- X-ray: hidden joints to the agreed scope.
- Manual QC: workmanship review.
- 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 Halogen-Free 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
For direct email: [email protected]. A quote request does not authorize purchasing, substitutions or production.
Halogen-Free PCB questions
Does halogen-free mean RoHS compliant?
No. These terms address different requirements. State each applicable requirement separately and agree the documentation needed for your product.
Is every high-Tg laminate halogen-free?
No. Tg and halogen content are separate material characteristics. Request an identified grade that satisfies both requirements if both are needed.
Can you declare the complete PCBA halogen-free from the PCB material alone?
No. Components and other assembly materials may need separate declarations. Define the complete product scope and required evidence during the RFQ.
