What files do you need to evaluate a PCBA project?

Send Gerber files (RS-274X or ODB++), a BOM with manufacturer part numbers, the pick-and-place (centroid) file and an assembly drawing. If you need functional testing, add the test specification, firmware and any test fixture requirements so FCT can be planned before production.

Do you support low-volume prototypes as well as mass production?

Yes. The same SMT lines handle engineering prototypes, pilot runs and volume production. Small batches carry a higher unit cost because stencil, line setup and component reel minimums are spread across fewer boards; our engineers advise on panelization and alternate parts to reduce that cost.

How do you control PCBA quality?

Quality is controlled in a closed loop: incoming material inspection, 3D SPI after solder paste printing, AOI after reflow, X-ray inspection for BGA and hidden joints, and functional testing before packing. Workmanship follows IPC-A-610 Class 2 by default, with Class 3 available on request, and the process targets a first-pass yield of 98.5% or higher.

Can you source the electronic components for us?

Yes. We offer full turnkey service where we procure all components through long-term supply partners, partial turnkey where you consign critical parts, and consignment assembly where you supply all materials.

Can overseas buyers audit the factory before ordering?

Yes. Buyers can schedule an on-site audit at our Shenzhen facility or a live video audit covering material storage, SMT lines, inspection stations and traceability records.

Product Description

Frequently Asked Questions

Q What is the primary difference between OEM and ODM PCBA services?

OEM (Original Equipment Manufacturer) services build printed circuit board assemblies precisely according to your complete design and engineering specifications. ODM (Original Design Manufacturer) services cover both the design development and production phases, turning functional concepts into finished, production-ready boards.

Q What processes are included in your one-stop PCBA turnkey manufacturing?

One-stop manufacturing encompasses bare PCB fabrication, component sourcing, SMT surface mounting, DIP through-hole insertion, soldering, firmware programming, functional testing, and final quality control packaging.

Q Can mixed SMT and DIP through-hole technologies be handled on a single board?

Yes. Production facilities feature automated high-speed SMT lines for fine-pitch microcomponents alongside dedicated DIP lines with wave soldering and selective soldering for heavy-duty connectors, relays, and power electronics.

Q What quality assurance and inspection procedures ensure reliable PCBA delivery?

Standard quality protocols include Automated Optical Inspection (AOI), X-ray inspection for BGA and leadless packages, In-Circuit Testing (ICT), Functional Circuit Testing (FCT), and burn-in testing to verify electronic reliability under operating conditions.

Q What specific engineering files are required to request a formal quotation?

A complete quote requires Gerber files (RS-274X format), a detailed Bill of Materials (BOM) listing manufacturer part numbers and reference designators, assembly pick-and-place (Centroid) data, and any specific testing instructions.

Q Are these PCBA manufacturing processes optimized for industrial and IoT applications?

Yes. Assemblies engineered for industrial control and IoT devices utilize conformal coating, high-reliability solder alloys, and rigorous thermal testing to withstand harsh environments, electromagnetic noise, and extended operational lifecycles.
