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.

Procurement Insights

What Global Tier-1 Buyers Demand From PCBA Partners

Sourcing strategies have evolved from bare labor cost arbitrage to deep supply-chain transparency, lifecycle resilience, and zero-defect quality gates.

Granular Traceability (Lot & Reel)

Procurement teams require board-level 2D QR code serialization linking each PCBA directly to the component reel ID, reflow oven zone temperature, and post-assembly functional test log.

Technical Inquiries

Frequently Asked Questions (FAQ)

Crucial engineering and procurement answers for hardware project managers and strategic sourcing directors.

What engineering documentation is required to initiate a custom emergency lighting PCBA build?

To generate a comprehensive DFM and turnkey quotation, we need: (1) Gerber RS-274X or ODB++ files, (2) Detailed Bill of Materials (BOM) including exact manufacturer part numbers and approved alternative designations, (3) Pick-and-place centroid data, and (4) Test protocols (such as battery switch thresholds, input surge specs, and functional firmware programming guidelines).

How does Aozite ensure emergency PCBA boards comply with UL 924 and EN 60598-2-22 safety standards?

Compliance is built into both design verification and manufacturing. Our engineering team checks creepage and clearance distances during pre-production DFM. During manufacturing, boards undergo automated 100% dielectric withstand testing (Hi-Pot), simulated mains failure transfer checks, and rigorous automated optical inspection (AOI) to guarantee solder integrity across high-voltage traces.

Can you handle high-mix, low-volume (HMLV) orders alongside volume mass runs?

Yes. We deploy 8 flexible SMT production lines capable of rapid changeovers. Our engineering layout handles low-volume pilot prototype runs (e.g., 50 to 500 boards for regulatory agency certification batches) and scales up to volume batches running tens of thousands of units each month without retooling penalties.

What types of battery chemistries can your emergency lighting PCBA management circuits handle?

We fabricate control boards engineered for legacy Ni-Cd and Ni-MH packs, as well as modern high-density Lithium Iron Phosphate (LiFePO4) and Lithium-Ion systems. We customize the on-board charging firmware for precision step-charging, thermal monitoring via NTC thermistors, and deep discharge cutoff to prevent cell inversion.

What testing capabilities are performed before shipment to overseas buyers?

Every shipment undergoes a complete test loop: 3D SPI for solder volume, post-reflow AOI, X-Ray void inspection for power ICs and BGAs, and automated Functional Circuit Testing (FCT) that exercises line dropouts, emergency lumen output, driver switching, and communication bus loops (DALI/wireless).
