Quality Assurance

5-Stage Quality Verification Protocol

To eliminate defects and maintain dependable yields for overseas shipments, each production batch passes through our strict multi-gate inspection framework.

01

Incoming Material IQC

Every reel, tube, and bare PCB undergoes microscope visual verification, solderability check, and MPN matching against the approved BOM.

02

3D Solder Paste SPI

High-resolution solder paste inspection assesses volume, height, area, and bridging before components are placed by SMT mounters.

03

Automated Optical (AOI)

High-speed dual-sided AOI validates component presence, polarity, alignment, tombstoning, and solder meniscus quality after reflow.

04

X-Ray BGA / QFN Check

High-penetration X-Ray verifies hidden joints underneath BGAs, CSPs, and leadless power packages to detect bridging, voids, or cold solder.

05

Functional Test & FQC

Complete power-up, voltage rail verification, MCU programming, peripheral tests, and vacuum anti-static ESD packaging for worldwide delivery.

Procurement FAQ

Frequently Asked Questions for Overseas Buyers

What files are required to obtain a fast turnkey PCBA quotation?
To provide an accurate quote and DFM review, we require your Gerber files (RS-274X format), a complete Bill of Materials (BOM) in Excel format with manufacturer part numbers (MPN) and reference designators, a pick-and-place (centroid) file, and assembly drawings indicating critical polarity markings.
What is the minimum order quantity (MOQ) for PCBA production?
Our minimum order quantity for prototype and quick-turn PCB assembly starts from just 5 pieces. We seamlessly scale from NPI engineering validation to pilot runs and tens of thousands of production units.
How does Shenzhen Mivo Electronics Co., Ltd. ensure component authenticity?
We source components exclusively through authorized franchise distributors (such as Arrow, DigiKey, Mouser, Element14) and verified tier-1 direct manufacturers. In the event of obsolescence or extended lead times, we propose verified drop-in equivalents and obtain your written sign-off before procurement.
Can you handle customized testing, firmware flashing, and box-build assembly?
Yes. We build custom test jigs, burn programmed hex files via SWD/JTAG, perform functional input/output validation, and can integrate finished PCBA boards into custom enclosures with wiring harnesses, membrane switches, and thermal heat sinks.
How are assembled circuit boards packaged for international shipping?
All completed boards are packed in custom anti-static ESD bags with desiccant packs and humidity indicator cards. They are cushioned within compartmentalized ESD foam trays and packed in heavy-duty export shipping cartons suitable for air courier or air freight.
