Buying printed circuit boards (PCBs) isn’t just a transaction — it’s the start of a project’s heartbeat. A board with the wrong thickness, poor copper quality, or unreliable finish can turn a neat prototype into a pile of troubleshooting. Whether you’re a hobbyist soldering late at night or an engineer managing a small production run, choosing the right supplier affects cost, time, and product reliability. Think of your PCB source as the engine shop for your car: you want someone who knows tolerances and won’t skimp on the bearings.
Distributors like RS Components or Farnell act like well-stocked showrooms: they carry stock, offer fast shipping, and supply components and off-the-shelf PCBs or HATs for makers. Manufacturers such as special-purpose PCB fabs typically handle raw fabrication, low-volume prototypes, or advanced stacks. If you need quick components or commonly used boards, a distributor saves time. If you need custom board layers, controlled impedance, or quick-turn prototypes, a dedicated PCB manufacturer is the better route.
If you need parts, modules, or standard PCB kits fast, these UK distributors are go-to names. They balance stock, technical resources, and UK-based delivery options so you can keep momentum on your build.
RS Components is a major distributor that stocks a wide range of PCBs, prototyping boards, and board-level accessories. From perf boards to industry-standard breakout boards and HATs for single-board computers, RS is a reliable place to compare specs and source parts in one basket. Their technical datasheets and part search make it simple to match components to a board design.
Farnell, also known under the element14 brand for maker-oriented items, is popular for engineers who need datasheets and design-in support. They offer evaluation boards, development kits and stocked printed circuit boards from known makers. If you’re building from a reference design or prototyping with modular boards, Farnell is worth checking.
Rapid Electronics caters strongly to education, hobbyists, and small labs. They sell prototyping boards, pre-fab PCB strips, and educational kits that help bridge the gap between learning and doing. Rapid is especially useful when you need affordable prototyping materials without a lot of fuss.
CPC supplies a range of PCB-related products aimed at hobbyists and technicians. Their catalogue typically includes perfboards, PCB engraving kits, and small-scale PCB accessories. If you prefer browsing a broad catalogue for one-off items or quick buys, CPC is often a convenient choice.
Makers and Raspberry Pi enthusiasts in the UK often prefer specialist shops that focus on community projects, accessories, and small-scale PCB production. These suppliers tend to offer unusual boards, add-ons, and curated kits that mainstream distributors don’t stock.
Pimoroni is a UK-based maker company known for creative add-on boards, HATs, and breakout modules designed for single-board computers. If your project is small, playful, or Raspberry Pi-based, Pimoroni’s selection and friendly project guides help you pick the right board and accessories.
The Pi Hut is another UK favourite for Pi HATs, GPIO expansion boards, and small PCBs tailored to education and maker projects. Their stock is geared toward getting a Pi-centered project off the ground quickly with compatible PCBs and accessories.
When your design moves off the breadboard into a real product, you’ll need a PCB fab that can handle Gerbers, panelisation, controlled impedance, and possibly assembly. For prototypes and small runs, both domestic and overseas fabs can be competitive. These manufacturers serve the UK market and are widely used by hobbyists and startups.
JLCPCB is a global low-cost PCB manufacturer that ships to the UK and is popular for rapid prototypes. Their online quoting tool makes it easy to upload Gerber files and select options like board thickness, copper weight, and surface finish. Turnaround for prototypes can be measured in days, and price per board is attractive for volume testing.
PCBWay is another well-known online fabrication house offering prototype and small-batch boards. They provide add-on services such as assembly and quality checks, which is handy if you want part population handled in the same place you order fabrication. Many UK makers use them for affordable multi-layer boards and quick iterations.
Eurocircuits operates across Europe and is known for higher-quality prototypes and controlled processes. For UK buyers who want a balance between European standards and reliable lead times, Eurocircuits offers clear specification pages and useful online tooling advice. Their pricing is transparent, which helps when estimating project budgets.
Don’t overlook smaller UK fabs and electronics workshops. Local providers may charge a bit more per board, but the benefit is easier communication, potential for quick revisions, and a single point of contact for technical queries. If you value face-to-face support and local logistics, a nearby fab can be worth the premium.
Before you hit the “Order” button, understand a few core specs that decide whether a board will behave the way you expect in the real world. These aren’t mysteries; they’re like ingredients in a recipe—get them right and your project tastes great.
Standard consumer PCBs are usually 0.063 inches thick, which balances mechanical strength and manufacturing ease. If your product needs to be especially thin or rigid, you might opt for 0.031 inches or flex materials in thicknesses measured similarly. Always check whether the fab supports your chosen thickness for plated-thru holes and edge tolerances.
Copper thickness is commonly specified in ounces per square foot — 1 oz is a typical standard that provides a reliable current-carrying capacity. If you plan to route high currents, consider 2 oz or thicker copper to reduce heat and voltage drop across traces. The copper weight affects trace width rules and thermal performance.
Solder mask color is cosmetic, but finish choices — in particular HASL (hot air solder leveling), ENIG (gold), or lead-free HASL — affect component solderability and long-term reliability. ENIG is popular for surface-mount assembly and offers a flat, gold-like surface for fine-pitch parts. Pick a finish that matches your assembly process.
Every fab publishes minimum trace width and clearance rules; typical values for economical prototypes might be around 6 mil traces with 6 mil spacing, but high-density work often demands 4 mil or less. Match your CAD settings to the chosen manufacturer’s capabilities to avoid costly redesigns.
Assembling a board yourself is satisfying and cheap for small batches, but it’s slow for many tiny parts or complex BGAs. Assembly services offered by PCB fabs or third-party assemblers can save time and increase yield, especially if you need consistent soldering quality across a handful of boards. Consider outsourcing when your project includes many SMDs smaller than 0402 or when you need reliable solder joints for safety-critical functions.
Prototype pricing tends to be per-board and influenced by turnaround time, layer count, and special options. Production runs introduce economies of scale: per-board cost can drop dramatically when you panelise and order more boards at once. However, beware of hidden costs like testing, tooling, or minimum order quantities that can alter total project expense.
Small changes in design can reduce costs quickly. For example, standardise board size to fit common panel dimensions, keep layer count low where possible, and avoid exotic finishes for non-critical prototypes. Panelise identical boards to reduce handling costs during manufacture and choose common hole sizes to lower drilling charges. Think like a frugal chef: reuse the same ingredients cleverly to feed more people.
When ordering PCBs, plan component sourcing simultaneously. Many UK distributors stock both PCBs and components, which simplifies logistics and sometimes allows combined assembly services. For niche parts, international suppliers can be cheaper, but factor in shipping time and customs. Keeping a parts list in parallel with your PCB Gerbers will reduce surprises during assembly.
Most reputable fabs offer a DFM check to spot potential issues like unmanufacturable trace widths, insufficient annular rings, or solder mask slivers. Run these checks early — they are like a spellcheck for your board files. A quick DFM pass can save days of back-and-forth and avoid rework that eats both schedule and budget.
Environmental considerations are becoming mainstream. Ask fabs about lead-free solder processes, recyclable packing, and responsible material sourcing. Choosing a manufacturer with transparent practices can align your project with greener standards and sometimes meet regulatory needs for certain markets.
Decide based on project stage and priorities. If you need a one-off evaluation board fast, go with a distributor that stocks ready-made modules. If you’re iterating designs weekly, use a fast-turn prototype fab with low minimums. For the first production run, balance cost and quality, and consider a local partner for tighter collaboration. It’s like choosing a coach for a marathon: pick someone who matches your pace and knows the course.
Don’t skip reading the manufacturer’s capabilities; don’t forget panelisation if you’re ordering many copies; don’t assume your CAD default settings match the fab’s rules. Also, avoid last-minute design changes that negate the cost advantage of batch orders. A calm, checklist-driven approach beats panic and expensive rush fees.
Before you submit your Gerbers and BOM, run through a short checklist: confirm board thickness in inches, check copper weight in oz, set the surface finish, ensure trace and clearance rules match, and verify file formats. Attach assembly notes if needed, and request a DFM review. This checklist is your preflight routine — do it every time.
Conclusion: Choosing where to buy printed circuit boards in the UK comes down to matching your technical needs, timeline, and budget. Whether you pick a large distributor for convenience, a specialist maker shop for community-focused boards, or an overseas fab for low-cost prototypes, the key is understanding the specifications that matter and communicating them clearly. With the right supplier, your design will move smoothly from idea to soldered reality.
