Five boards. A few dollars.

JLCPCB — Jialichuang — is a high-volume printed-circuit-board manufacturer based in Shenzhen, China, that sells prototype and small-batch fabrication directly to anyone with a web browser. There is no sales call, no minimum-order negotiation, no account manager. You upload a design, see an instant price, pay, and wait. By its own numbers the company runs 17 million-plus orders a year for 7 million-plus customers across 180-plus countries.

What makes it matter isn't the volume — it's the floor on cost. A two-layer FR-4 prototype starts from roughly $2 for five pieces, with FR-4 builds turning around in as little as 24 hours. On top of bare-board fab, JLCPCB runs an SMT assembly service: hand it a bill of materials and it will solder the surface-mount components onto the boards for you, drawing parts from a stocked library of more than 690,000 components. Bare board to populated board, design to doorstep, without you owning a single machine.

For most of the history of electronics, getting a custom PCB made meant a board house with a four-figure minimum order, a setup fee, and a lead time measured in weeks. That maths killed iteration. If a prototype cost hundreds of dollars and a fortnight, you couldn't afford to be wrong — so you over-engineered the first spin, agonised over it, and learned slowly. Hardware moved at the speed of its prototyping budget.

JLCPCB and the wave of cheap Shenzhen fabs around it collapsed that. When five real boards cost a few dollars and arrive within the week, being wrong becomes cheap. You spin a revision to test one idea. You order three variants at once. You fail fast on hardware the way software people fail fast on a branch. That single shift — cost and lead-time falling through the floor — is what democratised hardware prototyping: it put a professional fabrication line within reach of a student, a maker, a garage startup, anyone with a design and a card.

The configuration choices are real engineering decisions, not cosmetics. Surface finish trades cost against shelf life and fine-pitch solderability — cheap HASL for most prototypes, flat gold ENIG when you have dense fine-pitch parts. Solder-mask colour is mostly taste, though some colours and finishes sit at the cheaper promotional tier and others cost more. Layer count and board size drive most of the price. The DFM (design-for-manufacture) check is the safety net: it compares your design against the fab's minimum trace width, drill size, and annular ring, and tells you what won't come out clean.

EasyEDA is the free, browser-based schematic-and-PCB design tool. LCSC is the component distributor — the parts warehouse. JLCPCB is the board fab and assembly line. The three operate as independent websites with their own logistics, but they're a coordinated group, and the integration is the point: a component you place in EasyEDA carries its LCSC part number, that number flows into the JLCPCB assembly order, and the part JLCPCB solders is the one LCSC stocks. No re-keying a netlist, no "is this the same capacitor" guesswork across three vendors.

The parts-library advantage follows directly. Because JLCPCB pre-stocks a curated subset of LCSC's catalogue on its assembly lines — the Basic-tier parts — it can assemble small batches cheaply and fast, without waiting on procurement for every job. The library is the moat: a fab that already owns the parts in your BOM is a fab that can populate your board this week. The same group also runs adjacent services — CNC machining, 3D printing, and stencils — rounding out a one-stop path from idea to physical object.

For a South African team, JLCPCB's headline price is the easy part. The board genuinely is a few dollars. The honest reckoning starts the moment it leaves Shenzhen. Everything ships from China, which means two real costs stacked on top of the quote: time and import charges. On lead time, you choose your poison — an express courier (DHL, FedEx) lands the parcel in roughly a week but costs more than the boards did; economy or postal shipping is far cheaper but can take three to six weeks, and the tracking goes quiet somewhere over the Indian Ocean. For a fast prototype loop, the courier fee, not the fab, is your real per-spin cost.

Then customs. A parcel arriving in South Africa is liable for import duty (PCBs and assembled electronics fall under tariff lines that may attract a percentage duty) plus 15% VAT charged on the landed value — goods plus shipping — and usually a customs-clearance or disbursement fee from the courier on top. A "$10 of boards" order can arrive owing a few hundred rand before SARS releases it, and the courier will hold the parcel until you pay. Budget for it; don't be ambushed by it. Declaring value honestly and keeping the commercial invoice handy speeds clearance.

Set against that is the local alternative: domestic PCB fabrication in SA exists but is scarce, slower for small prototype runs, and materially more expensive per board. For most small teams the calculus still favours JLCPCB — you eat the shipping and the import line and still come out ahead — but the right move is to batch. Consolidate revisions, order a few projects together, pay the courier and customs overhead once across a bigger box rather than per dribbling order. The fab is global and cheap; the friction is entirely at the border, and batching is how you amortise it.
