PCB Manufacturing and Assembly,
Since 2018 — Built on 2007
A board house built in the opposite order to most: nineteen years of buying, stocking and assembling parts came first — fabrication followed in 2018.
The Company At A Glance
Mars PCB Innotech is the manufacturing and assembly arm of a group that has traded electronic components since 2007. Founded in 2018 in Shenzhen, it fabricates 1–64 layer boards, HDI, rigid-flex and high-frequency PCBs, runs turnkey SMT assembly with in-house component sourcing, and serves customers in more than 80 countries.

We Started With The Parts, Not The Board
Mars began in 2007 in Hong Kong as a component distributor, not a factory. The first lines were TI, Onsemi, Xilinx and ADI — power management, analog and discrete parts, sold to design teams across Asia. For a decade the work was narrow and clear: buy authorized, hold stock, ship fast.
The move into manufacturing came from the customer base rather than from a strategy deck. In 2017 the group opened a Shenzhen operation, working ADI and TI lines and pushing past distribution into one-stop electronics — schematic design through to finished product. That year we bought our first SMT lines and started assembling what we sold.
In 2018, we added the layer underneath it. Mars PCB Innotech was set up as a fabrication house, staffed by people who had spent their careers in front-line production and customer service at leading Chinese PCB manufacturers. Parts, board, assembly: one order, one supply chain, one set of lot records.
Most board houses learn components late, as a procurement service bolted onto fabrication. We learned fabrication late, on top of a decade of buying parts.
The rest has been reach and portfolio. 2019 brought the overseas PCB business, and the ST, NXP and Microchip lines alongside the originals. 2022 added domestic Chinese brands — Rockchip, HDSC, Shanghai Belling — as customers began designing them in for cost and supply security. In 2024 the trading side was formalized as Mars Electronic Technologies Limited, set up to run global distribution on its own footing.
Today the group works in sequence: procurement and export in Hong Kong, sales, engineering and stock in Shenzhen, layout and assembly in Guilin. The parts and the board are quoted together, shipped together, and traced back to the same records.
Four Services, One Supply Chain
PCB Fabrication
Rigid, HDI, rigid-flex, flex, aluminum and metal-core, ceramic, heavy copper, high-frequency and IC substrates. Up to 64 layers, 1.2/1.2 mil line and space, microvia, blind and buried vias.
Component Sourcing
BOM kitting, obsolete and allocation parts, excess inventory handling. 80% of supply from original manufacturers and tier-1 distributors, with lot-level traceability.
PCB Assembly
SMT, through-hole, BGA down to 0.35 mm pitch, mixed technology, box build and functional test. Prototype runs from 24 hours, through to volume programmes.
Design & Engineering
Schematic capture, layout, stackup and impedance design, mechanical design, and a DFM review that happens before you commit to tooling — not after.
What We Can Build
Full tolerances by board type are published on each capability page, so you can check a design against the real limit before you send it. If a feature sits outside the table, ask — we would rather tell you no at quote stage than at incoming inspection.

Three Sites, Three Jobs
Sales, engineering interface, component stock and outgoing quality control. Same-day dispatch on stocked items; 2–3 days to most of Asia.
Overseas purchasing, bonded logistics and export documentation. It is why a US purchase order can move without a currency or customs detour.
Layout team, SMT lines, through-hole, box build and test. High-mix, small-batch work runs here alongside volume programmes.

The People You Will Actually Talk To
Michael Xiao
25 years in PCB fabrication, previously front-line production management at a top-tier Chinese PCB corporation. Owns supplier qualification and capacity planning.
Hank Hu
18 years in high-speed and HDI layout. Runs DFM review, stackup design and the impedance sign-off that goes out with every high-layer quote.

What We Check, And What We Hand Over
Reliability in PCB is mostly a documentation problem before it is a manufacturing problem. Every order leaves with a traceable record: the material lot, the process route, the inspection results and the operator sign-off for each critical step.
Inspection We Run In-House — Bare Board
- AOI, flying probe, fixture ICT
- TDR/VNA impedance verification
- Micro-section, thermal shock
- Solderability, ionic cleanliness
Assembly
- Solder paste inspection, pre- and post-reflow AOI
- X-ray and CT for BGA and QFN
- In-circuit and functional test
- Burn-in on request
Incoming Components
- XRF, X-ray, decapsulation and electrical test on high-risk lots
- SGS or CNAS third-party reports available on request
Four Things That Are Hard To Copy
One roof, one accountability
When a board fails at function test, the fabricator and the assembler usually spend a week pointing at each other. Here they are the same team, in the same building. Root cause gets found, not negotiated.
DFM before tooling, not after
Every quote includes a manufacturability review. We flag the features that will cost you yield — 3 mil lines on a 6-layer stackup, an unnecessary 0.2 mm drill, a via-in-pad with no fill — and tell you what to change before you pay for it. Customers regularly cut 20–30% off a first build this way.
Parts and boards bought together
Component sourcing sits inside the same company, so a BOM shortage surfaces during quoting rather than three weeks into production. 80% of supply comes from original manufacturers and tier-1 distributors, with lot traceability to the original date code.
Answers in hours, in your time zone
Technical questions get an engineering answer within 24 hours, in English or Chinese, from the engineer handling your file. Not a sales reply asking you to repeat the question.
In Their Words
We were all extremely impressed with our first experience with Mars. Prior to contacting you, we reached out to many other PCB manufacturers and could not find anybody to do a one-day turn on this size board. We were really in a time crunch and Mars came through for us.
Where Our Boards End Up
Each segment carries its own rules — IATF discipline for automotive, ISO 13485 traceability for medical, IPC Class 3 for high-reliability work — and we quote and document accordingly.
Questions Buyers Ask Before The First Order
Our headquarters is in 1118T3 Guang Yin Building, #38 South Futian Road, Futian Street Port Community, Futian District, Shenzhen, Guangdong, China. We also operate an overseas procurement and logistics office in Hong Kong and a design and assembly facility in Guilin, Guangxi.
Mars PCB Innotech was founded in 2018 as the PCB manufacturing arm of a group that has traded electronic components from Hong Kong since 2007. The fabrication team came from leading Chinese PCB manufacturers, bringing more than 20 years of production experience with them.
Rigid boards from 1 to 64 layers, HDI and any-layer HDI, ELIC, rigid-flex, flex, aluminum and metal-core, ceramic, heavy copper, high-frequency materials and IC substrates. Minimum line and space is 1.2/1.2 mil in volume production.
Yes. Component sourcing is an in-house function, covering BOM kitting, obsolete and allocation parts, and excess inventory. About 80% of supply comes from original manufacturers and tier-1 distributors, with traceability back to the original lot and date code.
ISO 9001:2015 quality management, UL, ISO 13485, IATF 16949, RoHS and REACH. Certificates with scope and registration numbers are available on request.
Prototype fabrication starts at 24 hours for simple 2–4 layer boards; 8–12 layer boards typically run 5–7 working days; assembly adds 3–5 days after parts arrive. Volume schedules are confirmed at quote stage against material availability.
Send Gerber files and a BOM through our quote page. You will get a manufacturability review and a priced quote within 24 hours, including alternative parts where something on the BOM is short or obsolete.
A Day On The Floor Tells You More
Than Any Brochure
Customers are welcome at both sites. If you are sourcing seriously, we will walk you through the lines, the inspection equipment and the boards currently in production.
