If you've ever tried to source components for a prototype build, you know the drill: you need 10 units of a specific MCU, 20 of a power management IC, and 50 each of a handful of passives. You call a major distributor. They tell you the MOQ on that MCU is 3,000 pieces, the power management IC is on 16-week lead time, and the passives come in full reels of 5,000. Your prototype bill of materials — maybe $800 worth of components — now has a $22,000 procurement price tag and a four-month timeline. That's not prototyping. That's punishment.
ADD Components' quick-turn prototype PCBA service was built to solve exactly this problem. We source the tiny quantities that big distributors won't touch, deliver them to a partner assembly factory, and ship assembled prototypes — in as little as seven days from BOM approval to your door.
Why Prototype Component Sourcing Is Broken
The authorized distribution channel is optimized for production volumes. It's a machine that runs beautifully when you order a full reel of 3,000 microcontrollers and 50 reels of passives — and grinds to a halt when you ask for 10 of each. The reasons are structural: authorized distributors have franchise agreements that impose minimum order values, rebate structures tied to quarterly volume, and sales teams compensated on revenue, not order count. A $2,000 prototype order generates roughly $120 in commission. The same salesperson can spend that time on a $50,000 production order.
Startups, R&D labs, and engineering teams building proof-of-concept hardware fall into a gap: too small for authorized distribution to care about, too specialized for hobbyist retailers to stock, and too time-sensitive to wait 14 weeks for factory lead times. That gap is where ADD Components operates.
How ADD's Quick-Turn Prototype Service Works
Day 1: BOM intake and feasibility check. Send your BOM (with manufacturer part numbers and quantities) and Gerber files to ADD. Our team reviews for lifecycle risks, lead time red flags, and availability. If any MPN is unavailable, the 48-hour cross-reference service identifies pin-compatible alternatives immediately — not after a week of back-and-forth.
Day 1–3: Component procurement. ADD sources every line item through our 3,000+ channel network. We buy the exact quantities you need — 10, 20, 50 pieces — from channels that handle broken-reel, cut-tape, and tray splits. No inflated MOQs. No full-reel surcharges passed to you.
Day 3–5: Incoming QC and assembly prep. Components arrive at our partner factory. BGA and QFN packages go through X-ray verification. Solder paste stencil is fabricated. Pick-and-place program is generated from your centroid file.
Day 5–6: Assembly. SMT placement on quick-turn prototype lines. Mixed-technology boards may add one day for through-hole and selective soldering.
Day 6–7: Testing, inspection, and DDP shipping. AOI inspection on every board. Optional functional testing (client-supplied protocol). Boards ship via DDP in 5–7 days, so you receive them with all duties and customs handled.
What Makes This Different from Fab Houses
Most PCB prototype services (the JLCs and PCBWays of the world) are excellent at fabricating bare boards fast. Their component sourcing, however, is limited to their in-house inventory of commodity passives and a narrow selection of ICs. If your BOM includes anything non-commodity — a specific TI battery charger, a Microchip USB hub controller, a u-blox GNSS module — their system either can't source it or quotes an absurd price for the small quantity. ADD solves the component problem first, then handles assembly. The result: you can spec the components your design actually needs, not the components that happen to be in someone's in-house library.
Who This Is For
Quick-turn prototype PCBA serves hardware startups preparing for a demo to investors, R&D teams validating a new design before committing to production tooling, and industrial equipment manufacturers building one-off test fixtures or field trial units. If you need 5 to 200 assembled boards, fast, and you don't want to fight with MOQs and lead times — this is your service.
Send your BOM and Gerber files to info@addcomponents.hk for a prototype PCBA quotation. We'll confirm feasibility within 24 hours and give you an honest timeline — typically 7 to 12 calendar days from approval to shipment.
