The company behind the network

Who you are actually contracting with: a trading house, not a factory's own website and not a broker. Here is what we own, what we do not, and how we are paid.

01Who we are · stated first

A trading house and supply-chain integrator.

24 partner sites6 services1 contract

Role We are not the manufacturer Except at the board level, the products we sell are made by named partner sites. We say so on the first line, not the last.

Three layers Network, services, backstop The 24 independently operated sites we represent, the six service lines that carry a deal, and our own PCB & PCBA factory as the engineering backstop.

Since Trading in Shenzhen since the early 1990s 30+ years, and every service line running on an established SOP rather than on an individual favour.

What we are not Not a factory, not a broker We do not present the partner plants as ours, and we do not disappear after the deposit. One contract, one accountable party.

An SMT line seen down its length: pick-and-place machine, reflow oven and boards on the conveyor — Fig. 01Our own line. The backstop: 9 SMT and 5 DIP lines in Bao'an, never counted among the 24.

An oblique elevated view of a container yard, long parallel rows of identical containers stacked two high with even aisles between them — Fig. 02The export motion. Documents, freight, customs and collection are carried by us, in our name.

Five finished power products staged in one row: a rack battery shelf, a supercapacitor module, a CRPS module, a vertical PDU and a coupling manifold plate — Fig. 03What that means in practice. Finished products, made by sites we represent rather than own.

Visitors in anti-static coats walking an assembly-hall aisle between rows of SMT machines, seen from behind — Fig. 04The network is walkable. A buyer can stand on the floor of a partner site in the same week as ours.

02Trust layer · the six numbers

Six numbers, and what each one is not.

No seventh statistic existsProduct specs are separate

The complete set of company statistics used anywhere on this site
Number	What it means	What it is not
30+ years	Trading in Shenzhen since the early 1990s	A claim about the age of any partner site
100,000+	Cumulative customers served, domestic and international	Never a count of orders and never a count of deals closed
45,000 m²	Our own PCB & PCBA factory in Bao'an, Shenzhen	Never counted among the 24 partner sites
500+	People across the factory and the company together	Not a headcount for the network
6	Service lines, all running on established SOPs	Not six departments, offices or subsidiaries
24	Partner sites in five capability groups	Not owned by us; each one is independently operated

A single technical drawing sheet on a pale surface with a pen, dividers and one tab marking a clause — Fig. 05Numbers are defined, not decorated. Each one carries its own boundary in the column beside it.

Five finished objects in one level row on a plain pale surface, including a rack battery shelf and a machined coupling pair — Fig. 06Product figures are unrestricted. Layer counts and kW ratings belong to the products, not to the company.

Three items on a plain background: a microscope eyepiece, a sealed sample bag with a blank label and a plain laboratory courier box — Fig. 07No seventh statistic. Where a number does not exist, the field stays empty rather than invented.

A technical drawing flat on a pale bench with digital calipers, a drafting triangle and sample parts resting on it — Fig. 08Every figure is checkable. The network's counts come from reading each site's own published list.

03Execution layer · where we sit

Between your specification and the container.

FOB by defaultFCA inlandCFR / CIF only when we sell the freight

The site The partner makes the product Each of the 24 sites is an independently operated business with its own quality system, its own lines and its own published numbers.

Our work Specify, assess, follow, inspect, export We specify the product with you, assess it, follow it through production, inspect it before shipment, and carry the export documents under one contract.

Terms The export declaration stays in our name We quote FOB by default and FCA when the goods are stuffed inland; CFR or CIF only when we are selling the freight. We do not quote EXW.

Position Deliberately visible Being a trading company is not a disclaimer. It is the reason one contract can cover twelve product categories at once.

Pick-and-place heads and feeder reels aligned along a single SMT line, seen close down the line — Fig. 09Production is the partner's. The build happens on their line, to the specification we agreed with you.

A wide production floor from a raised viewpoint, three rows of identical assembly machinery and painted walkways — Fig. 10Capacity comes from the site. Lead times are quoted from their lines, not from our brochure.

An engineering bench under an inspection lamp with a finished board assembly, a magnifier arm and sample connectors — Fig. 11The assessment is ours. A written review, signed by the engineer who read your file.

04Trust layer · what we own

What we own, and what we do not.

45,000 m² own factory9 SMT + 5 DIPUp to 58 layers

We own Our own PCB & PCBA factory 45,000 m² in Bao'an, Shenzhen, 500+ people, 9 SMT and 5 DIP lines, fabrication up to 58 layers.

We own An engineering and solutions team They write assessments rather than sales notes, and the engineer who reviews a file signs the answer.

We do not own The 24 partner sites They are independently operated businesses we represent and qualify, not plants we control.

We do not hold A citable certificate of our own Certifications belong to sites, and we report them as counts. No holder name and no certificate number is published on this site.

Every product has a board inside. We own the board.

A finished populated circuit board assembly standing upright on edge with a matte black heatsink across its upper half — Fig. 13Why the board matters. It is usually where a product fails first, and it is the part we build ourselves.

A production panel of identical bare boards held in a white inspection fixture, gold pads and teal solder mask — Fig. 14One engineering baseline. Our engineers read a partner's stackup with the same eyes they use on our own.

Three finished fanless industrial computers in a row, closed enclosures with no boards visible — Fig. 15The trust floor, not the subject. The board narrative stays in this section; what you can order is the larger part of this site.

Five items in one level row on a pale ground: a blank lot tag, a shallow tray of identical boards, a test fixture, a sealed module and a sealed carton — Fig. 16What ownership buys. Records we can hand over: lot tag, batch tray, fixture, sealed unit, carton.

06Trust layer · the commercial model

How we are paid, in writing.

Base is the factory priceOn FOB termsNo side payments

The base Commission on the factory price, never on landed cost Where commission applies, the base is what the factory quoted on FOB terms — not a figure inflated by freight, duty or insurance.

Disclosure Which factory quoted what We will state in writing which site produced a quotation, so the comparison you are making is the real one.

Kickbacks We do not accept payments from factories No payment reaches us from a site behind a buyer's back, and we will put that commitment in the contract on request.

Market context Why this is stated at all Kickbacks are estimated at 10–15% of order value with hidden markups of 10–30%, and more than 50% of agents are estimated to take them — an estimate published by sourcing firms, not an accusation.

Two technicians at a bench reviewing a supplier quotation, seen from the chest down and from behind — Fig. 17The quotation is a document. One factory price, stated once, with the site named.

A container terminal yard at first light, long parallel rows of identical containers receding into the distance — Fig. 18Freight is not a mark-up. CFR or CIF is quoted only when we are the party selling the freight.

A flat technical diagram of a route line with four stage markers and two teal transfer bars — Fig. 19The commercial model decides behaviour. That is why it is on the page rather than in a side letter.

A dense industrial district at blue hour, rows of low factory roofs and container yards receding toward a pale horizon — Fig. 20The base is a factory price. Not a landed number inflated by freight, duty or insurance.

07Trust layer · the limits

What we will not claim.

No awardsNo client namesNo certificate of our own

A bright assembly hall seen down a central aisle between two rows of identical SMT machines — ANo awards we have not received. No logos of companies that have not bought from us, and no borrowed track record.

A line-up of finished consumer and terminal products: a delivery robot, a thin display panel, smart glasses and an enclosed 3D printer — BNo adjective without a number. If a claim cannot carry a number, a standard code or a named mechanism, it does not go on the page.

A production floor seen as depth layers: an SMT line, a sheet-metal bending cell and further work areas along one aisle — CNo certificate of our own. Where a partner publishes none, we say that plainly and lead with patents, models and shipping volume.

30+ years · 100,000+ cumulative customers served · 45,000 m² own factory · 500+ people · 6 services · 24 partner sites. That is the complete permitted set of company statistics on this site.
