Company Profile
A Shenzhen Electronics Manufacturer Built for Overseas Buyers
Located in the world's largest electronics supply hub, with direct access to board houses, component distributors and assembly lines.
Who We Are
Shenzhen Mivo Electronics Co., Ltd. is a manufacturer based in Guangdong, China, specializing in PCB fabrication, electronic component purchasing and one-stop PCB assembly. Alongside circuit boards, we produce custom parts to drawing — sensors, cable assemblies, modules, heat sinks, membrane switches and SMT stencils.
Our team of 51–100 people works with engineers, importers and product companies who need low-volume prototypes today and stable repeat production tomorrow. Small minimum orders, transparent part substitution and English-language project communication are how we earn long-term business.
Before you place an order, you can verify us independently: our premises have passed an Alibaba.com onsite check, our legal status is confirmed by a third-party verification company, and our transaction records and buyer reviews are public.

How We Work
Our 6-Step Turnkey PCBA Workflow
Every project follows the same documented sequence, so you know what happens to your files and who is responsible at each stage.
File Review & DFM
Engineers check Gerber, BOM and centroid data for footprint, polarity and manufacturability issues before production.
Component Sourcing
Parts are purchased by manufacturer part number; any alternative is sent to you for written approval first.
PCB Fabrication
Bare boards and matching solder paste stencils are produced to your stack-up, finish and solder mask specification.
SMT & THT Assembly
Surface-mount placement and through-hole soldering, followed by firmware programming when required.
Inspection & Testing
Boards are inspected and functionally tested according to the test plan and fixtures you specify.
Packing & Shipping
ESD-safe packaging and labeling, then export shipment to your warehouse worldwide.
Engineering Notes
Choosing the Right Board Technology
A quick comparison our engineers share with buyers who are deciding between substrate types for a new product.
| Technology | Main Advantage | Typical Applications |
|---|---|---|
| FR-4 Multilayer PCB | High routing density and controlled signal paths in a compact footprint | Industrial controllers, IoT devices, robot mainboards |
| Aluminum Core PCB (MCPCB) | Metal base spreads heat away from LEDs and power devices | LED lighting, power drivers, motor control |
| Flexible Printed Circuit (FPC) | Thin polyimide circuits that bend and fit tight 3D spaces | Wearables, display links, compact sensors |
| Membrane Switch Panel | Sealed, low-profile keypad combining graphics and switching | Industrial equipment HMI, medical and appliance front panels |
| SMT Solder Paste Stencil | Accurate, repeatable paste deposit for fine-pitch parts | Any SMT assembly run, from prototype to volume |

Buyer FAQ
Frequently Asked Questions
What is the minimum order quantity for PCB assembly?
Prototype and custom PCBA projects start from 5 pieces. Bare PCB fabrication listings typically start from 100 pieces, while sensors start from 10 pieces and catalogue components range from 100 to 2,000 pieces depending on the part.
Which files are needed to start a PCBA project?
Please provide Gerber files (RS-274X), a BOM with manufacturer part numbers, a pick-and-place (centroid) file, an assembly drawing with polarity marks, the order quantity and any functional test requirements.
Can you source electronic components for my BOM?
Yes. We purchase components through the Shenzhen electronics supply chain. If a part is obsolete or on long lead time, we propose a cross-reference alternative and only use it after your written approval.
Do you manufacture custom sensors and cable assemblies?
Yes. We build custom PT100 RTD probes, NTC battery temperature sensors, SHT30 humidity probes, water leak sensing cables, 36AWG micro coaxial cables, modules and heat sinks to drawing.
Is Shenzhen Mivo Electronics a verified supplier?
Our premises passed an onsite check by Alibaba.com staff and our legal status was confirmed by a third-party verification company. We have traded on Alibaba.com for 8 years with an average buyer rating of 4.7 out of 5.
