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 electronic assembly services are covered for IoT and smart hardware?

Comprehensive turnkey PCBA solutions are supported, including precision SMT placement, through-hole assembly (THT), component sourcing, firmware programming, and functional testing tailored for compact IoT and smart devices.

Q What files are required to get an accurate PCBA quote?

To receive a detailed and precise quotation, please provide complete Gerber files (RS-274X format), a structured Bill of Materials (BOM) including manufacturer part numbers, pick-and-place (centroid) data, and any specific assembly requirements.

Q What quality control and inspection standards are applied during assembly?

All assemblies strictly adhere to IPC-A-610 standards. Production lines implement multiple inspection stages, including Automated Optical Inspection (AOI), X-ray inspection for BGA/QFN packages, In-Circuit Testing (ICT), and functional testing (FCT).

Q Do you support both OEM and ODM custom manufacturing?

Yes, full OEM and ODM production capabilities are provided. Services cover custom circuit board fabrication, precision component mounting, custom enclosure fitting, wire harness integration, and final retail box packaging.

Q What is the typical turnaround time for prototype and mass production?

Quick-turn PCBA prototyping can typically be finished within 24 to 72 hours once components are ready. Standard mass production runs generally require 2 to 4 weeks depending on BOM lead times and order quantities.
