Unrivaled Excellence in PCB Manufacturing
Submit the design conditions for engineering review and confirm the executing site, process limits and any coordinated manufacturing activities.
Tailored PCB Solutions with Material Options
Our Rigid PCBs, crafted from materials like FR - 4, CEM - 1, or High - TG laminates, ensure robust structural integrity, making them ideal for industrial automation and telecommunications. For space - constrained applications, Flexible PCBs utilize polyimide or polyester substrates, providing design flexibility without sacrificing performance. Rigid - flex PCBs combine the best of both worlds, integrating multiple rigid layers and flexible interconnections using advanced composite materials.
Multilayer and HDI PCBs, constructed with high - performance dielectrics and copper foils, meet the high - density and high - speed demands of modern electronics. Aluminum PCBs, with their aluminum substrates and thermally conductive dielectrics, offer excellent thermal management for LED lighting and power supplies. High - Frequency PCBs rely on low - loss materials such as Rogers and Taconic to ensure superior signal integrity in 5G communication and radar systems.
We also specialize in Thick Copper PCBs for high current - carrying applications, LED PCBs with customized designs, Ceramic PCBs for high - power and high - temperature scenarios, and more, each tailored to specific industry requirements.

Specify bare PCB supply for your assembly project
Bare board fabrication and Thailand assembly are different supply steps. Confirm the fabricating partner, country, specification and acceptance evidence in the quotation.
| Specification | Customer provides | Supplier confirms |
|---|---|---|
| Board construction | Gerber / drill files, stackup, material and finished thickness. | Compatible combined construction, laminate availability and fabrication questions. |
| Conductors and holes | Copper, track / space, hole and via requirements. | Feasible process conditions, tolerances and the agreed controlled drawing. |
| Finish and acceptance | Surface finish, impedance, inspection class and packaging. | Inspection / electrical test scope, applicable reports and any external testing. |
Handover and acceptance
The purchasing output is an agreed fabrication specification, approved exceptions and the required lot / test records. Minimum feature dimensions are design-dependent and must be confirmed for the proposed fabrication source.
Is there a minimum order quantity (MOQ) for product orders?
Minimum quantity and batch economics depend on the BOM, setup, testing and sourcing scope. Discuss your planned quantities with sales.
What is your testing policy and how you control the quality?
Agree the inspection and test plan for your product. Depending on the design and executing site, this may include PCB electrical checks, AOI, BGA X-ray inspection, first-article review and customer-defined functional testing. Confirm coverage and acceptance limits in the quotation.
What service do you have?
We can offer OEM service including PCBA making, PCB assembly, components sourcing. Additionally, we can also provide programming, testing, cables, enclosure assembly service.
Do you support quick proofing?
Confirm prototype timing after design review, material availability and the test plan have been checked.
Are my files safe?
Agree confidentiality terms, access permissions and the file-transfer channel with sales before sharing design files. Identify any approved partner access in the project agreement.
If we have order production needs, how can we contact you?
Request a PCBA Quote with your project stage, quantities, delivery country and test requirements. Sales will coordinate the next steps and file transfer.
