A PCB assembly order can be as small as a single board. We have no minimum order quantity, and our assembly quote accepts quantities from one piece upward. Small batch has no fixed definition in the industry, so the label matters less than how setup work, parts, and testing are spread across the boards you order.
What Counts as a Small Batch?
There is no industry-wide answer. Some companies call anything under a hundred boards a prototype run, treat a few hundred as low volume, and reserve small batch for a few thousand. Others draw the lines elsewhere. If you compare quotes from different companies, check which definition each one is using.
We do not ask you to fit a category. Our assembly capabilities cover orders from 1 piece to more than 10,000,000 pieces, and our low-volume service has no minimum order quantity. A single board, a pilot run of fifty, and a recurring order of a few hundred all start from the same quote page.
Three practical questions should drive your choice of quantity, rather than the label. How stable is the design? How long will the parts take to arrive? How soon will you build again? A design that is still changing is best built in the smallest quantity that lets you test it.
Why Quantity Changes the Price per Board
Every assembly order carries work that does not depend on quantity. Files have to be reviewed, a stencil has to be made, machines have to be programmed, and the first board has to be checked. On a large order, that work is shared among thousands of boards. On a single board, one board carries all of it.
That is why the price per board falls quickly as quantity rises, and why a one-piece order costs more per board than a larger one. It does not mean that small orders receive less attention. We give small quantity work the same care and attention as every other order.
If budget is tight, ordering a few more boards than you strictly need is often a better use of the fixed setup work than ordering exactly one. This is especially true when you expect the first board to reveal something worth fixing.
What Stays the Same at One Piece
The process around your files does not shrink with the quantity. You upload the same Gerber files, drilling file, and BOM, and the quote usually comes back within one to two working days. After your payment is received, we run a free DFM check on your design file and confirm your BOM, and production begins only after everything is clear. Our assembly services follow IPC Class 3 and RoHS requirements.
Parts Are Often the Real Constraint
On a small order, components usually need more attention than the assembly itself. Parts are sold in fixed pack sizes, and a build of a few boards uses only a fraction of a reel or tray. Tell us your quantity when you request a quote, so that the way your parts are packaged can be considered from the start.
We source parts from authorized distributors, and we do not substitute a part without consulting you first. If you already hold some of the parts, our consigned options accept reels, tubes, trays, partial reels, cut tape, and bulk, which suits small builds well. Add a small margin of spare parts to anything you supply, because placement losses weigh more heavily on a small build.
Starting Small and Growing
A small first order is not a dead end. Reordering does not require you to resend files, and there are no minimum cost requirements or added tooling charges when you reorder. If your design changes, note that apart from updates to the silkscreen and wiring layers, design modifications are placed as a new order.
Consider a team that needs five boards to validate a new controller. The first build reveals that one connector sits too close to a mounting hole. The team corrects the design and orders twenty boards for field trials, then a few hundred once the trials succeed. Each order is small, each one teaches something, and none of them requires a commitment to a larger quantity than the project can justify. That is the real value of having no minimum.
If you are still validating the design, our prototype assembly page covers the early stage. The same quote page handles the move to larger quantities later, so you do not have to change companies as your volume grows.
How to Request a Small Order
Open the assembly quote page and enter your quantity, even if it is a single board. Choose single-sided or double-sided assembly, and upload your Gerber files, drilling file, and BOM. If you need IC programming or custom testing, choose those options at the same time, and use the Notes field for anything else we should know.
A few misunderstandings come up often. Expecting the price per board to scale in a straight line leads to surprise at the single-board price, because setup work does not scale. Ordering exactly the number of boards you need leaves no room if the first board reveals a fault. Forgetting spare parts on a supplied kit can stop a small build over a handful of missing components. Changing the BOM between the first order and the reorder without telling us causes avoidable delays.
FAQs
1. What is the minimum order for PCB assembly?
There is no minimum order quantity. You can order a single assembled board.
2. Is a one-piece order handled differently from a larger one?
We give small orders the same care as large ones. Setup work is spread over fewer boards, so the price per board is higher.
3. Do I need a different quote form for a small order?
No. Use the same assembly quote page and enter your quantity.
4. Can I reorder without sending my files again?
Yes. Reorders do not require resending files, and no tooling cost is charged.
5. How long does the quote take?
It usually arrives within one to two working days. Larger quantities can take longer.
6. Can I supply my own parts for a small build?
Yes. We offer consigned and partial consigned assembly. Tell us how your parts are packaged.
A small first order is the least expensive way to find the problems in a design, and there is no minimum quantity standing in the way.
