Your trusted PCB and PCBA one-stop manufacturing partner

The Internet of Things turns everyday objects into connected, data-generating devices, and that demand pushes PCBs toward smaller footprints, lower power draw, and far higher integration. From smart sensors and wearables to gateways and industrial nodes, Donlly builds IoT boards that balance cost, size, and reliability for products that have to ship in volume and still run for years on a small battery. Our prototyping service turns your concept into a working sample in days, with 1-40 layer rigid, flex, and rigid-flex options, full AOI and electrical test, and lead-free processes suited to battery-powered designs. For connected products we routinely handle ultra-low quiescent-current layouts, RF antenna matching, EMI control, and miniaturization through HDI blind and buried vias - the details that decide whether a device meets its range and battery-life targets. When you move to volume, our one-stop PCBA line manages SMT, THT, and mixed placement from 01005 to fine-pitch BGA, with AOI, X-Ray, ICT, and functional testing so every connected device ships verified. We also run design-for-manufacturability reviews and can source hard-to-find components, helping you avoid the costly re-spins that delay a launch and erode margin. Quality discipline matters as much as speed: we work to IPC acceptance classes, keep process records for traceability, and align tests to your specification rather than a generic pass/fail. Whether you need a tiny rigid-flex tag, an HDI module, or a low-power sensor node with tight impedance control, Donlly supports the full path from sample to mass production under one roof, so your firmware and mechanical teams coordinate with a single board partner instead of juggling several. Beyond the bare board, we help IoT teams think about the whole build: panelization for cheaper fabrication, test jigs for fast functional checks, and firmware-friendly footprints that make flashing and debugging painless. Our engineering team joins design reviews early, so form-factor and antenna constraints are settled before tooling, not discovered after. The result is a connected product that is cheaper to make, easier to test, and faster to certify - exactly what a crowded IoT market rewards. If you are scoping a new device, send the schematic and we will flag the layout and sourcing risks before they cost you a spin.

Automotive electronics must survive heat, vibration, moisture, and years of continuous operation, so the bar for quality is among the highest in the industry. Donlly supplies PCBA for infotainment, body control, lighting, and advanced driver-assistance systems (ADAS) with processes built for repeatability and traceability from the first validation build onward. We assemble boards using SMT, THT, and mixed technology, with AOI, X-Ray, ICT, and functional testing at every critical stage. For space-constrained modules under the hood or behind the dashboard, our rigid-flex and HDI capabilities remove connectors and cut weight while improving signal integrity - a tangible win for both reliability and packaging. Automotive programs benefit from our component procurement and counterfeit-avoidance controls, plus tight process documentation that supports PPAP and automotive-quality expectations. We work to IPC-A-610 acceptance classes and can align to customer-specific reliability requirements, including extended temperature ranges and conformal coating where the application demands it. From a low-volume validation build to steady production, our one-stop model keeps your supply chain simple and your quality consistent across the vehicle's electronics. Engineering changes flow through the same line, so a fix validated on a prototype reaches the line without re-qualification surprises. We also plan for the unglamorous parts of an automotive program: controlled revisions, retained first-article data, and a bill of material that stays sourced as parts shift. When a model year changes, the board should change with it cleanly, not through a frantic re-qualification. Donlly's single-line model means the prototype you approved and the units on the line are built the same way, with the same tests - so your plant and your suppliers spend time building, not reconciling. Share your PPAP expectations up front and we will structure the documentation to match them from the first article. We routinely run low-volume validation and full production on the same line, so a pilot build and a ramp look identical.

Medical devices leave no room for failure, which is why Donlly treats healthcare PCBA with extra discipline: clean processes, full traceability, and electrical test on every board. We serve monitoring, diagnostic, imaging, and wearable therapy products where reliability is clinical, not optional, and where a single field return can carry consequences far beyond cost. Our rigid-flex and HDI capability is ideal for miniature, lightweight instruments and implantable-adjacent designs, while our prototyping service helps you iterate quickly during certification. Production runs go through SMT/THT/mixed assembly with AOI, X-Ray, ICT, and FCT, and we maintain process records that support ISO 13485-aligned quality systems and the audit trails regulators expect. We also help with component sourcing and obsolescence management, an important concern for devices with long lifecycles and locked bills of material. Design-for-manufacturability reviews catch issues early, reducing risk before a board reaches the patient and avoiding late, expensive redesign. Documentation is part of the product: lot traceability, test results, and controlled revisions travel with every shipment. From a first sample to audited production, Donlly delivers the consistency medical OEMs depend on, and a single partner across prototype and volume keeps your quality file coherent. We also plan for the unglamorous parts of a medical program: controlled revisions, retained first-article data, and a bill of material that stays sourced across a long device life. When a design is locked for regulation, the board should stay buildable without surprise, not drift through silent component changes. Donlly's single-line model means the sample you validated and the units on the line are built the same way, with the same tests and the same audit trail - so a clinical team receives a device that matches what was approved, batch after batch, year after year. Tell us your quality system early and we will align process records to it rather than retrofit them later.

Industrial equipment runs in harsh conditions - dust, shock, temperature swings, and round-the-clock duty - so control boards and sensing modules need rugged construction and dependable assembly. Donlly builds PCBA for PLCs, motor drives, instruments, and factory automation with an eye on long-term field reliability rather than just a passing bench test. Our prototyping service lets you validate a design quickly, then scale into production without switching suppliers, which protects your schedule and your documentation. The assembly line covers SMT, THT, and mixed placement with AOI, X-Ray, ICT, and functional test, and we handle larger, connector-heavy boards as comfortably as dense modules - useful when a controller mixes power, signal, and communication on one board. For harsh-environment duty we advise on conformal coating, connector selection, and thermal layout, and we keep process documentation that supports maintenance and traceability over a machine's multi-year life. That paperwork is what lets a technician rebuild or service a unit years later with confidence. Combined with component procurement and DFM support, our one-stop model keeps industrial programs on schedule and easy to service in the field. When a line goes down, the last thing you want is a board you cannot reorder or a supplier you cannot reach - Donlly keeps both within one relationship. We also plan for the practical side of an industrial program: spares that match the original build, documentation a field technician can actually use, and a supplier who is still reachable when a line needs a board three years later. Donlly's single-line model means the prototype you approved and the units on the line are built the same way, with the same tests - so a rebuild never becomes a rediscovery exercise. That continuity is what keeps factory uptime high and service costs predictable. For harsh duty, ask about conformal coating and we will quote it as part of the standard build, not an afterthought.

Telecom and 5G infrastructure demand signal integrity, controlled impedance, and dense, low-loss stack-ups. Donlly manufactures boards for base-station modules, small cells, routers, and RF front-ends where every decibel and millisecond matters, and where a marginal layout becomes a field complaint at scale. Our HDI and rigid-flex capability supports fine-pitch BGAs, blind/buried micro-vias, and tight impedance control across high layer counts. Prototyping delivers working samples fast so you can tune RF performance early, before tooling is committed, and our assembly line adds AOI, X-Ray, ICT, and functional test for production confidence on every unit. We work with low-loss materials and can advise on stack-up, grounding, and EMI control to keep your high-frequency design stable across temperature and load. Component sourcing and obsolescence planning help long-life network equipment stay buildable even as individual parts go end-of-life - a real risk for infrastructure meant to run for a decade. From lab sample to rolled-out hardware, Donlly keeps your connectivity products performing to spec. Because the same team handles prototype and volume, the impedance and stack-up you validated are the ones that ship, not an approximation re-derived by a second shop. We also plan for the practical side of a network build: spares that match the original board, documentation your integration team can trust, and a supplier still reachable when a node needs a replacement years later. Donlly's single-line model means the prototype you validated and the units shipped are built the same way, with the same tests - so a field swap never becomes a re-qualification. That continuity is what keeps a network consistent as it scales across sites and over time. Send us your stack-up and we will confirm impedance and loss before fabrication, not after the first return. We run low-volume pilots and full production on the same line, so a validation build and a scaled rollout match.

Consumer electronics live and die by speed-to-market, cost, and finish quality. Donlly helps brands and contract manufacturers move from Kickstarter prototype to retail-ready product without losing momentum, and without the quality dips that show up as returns after launch. Our prototyping service produces working samples in days for wearables, smart home gear, audio, and gadgets of every shape, with rigid, flex, and rigid-flex options. For production we run SMT, THT, and mixed assembly with AOI, X-Ray, ICT, and FCT, holding the yield that protects your margin on a product where pennies decide profitability. Miniaturization is where we add the most value: HDI blind/buried vias and rigid-flex hinges let you shrink a product while improving durability and removing the fragile connectors that break in users' hands. We also manage component sourcing and help avoid the supply surprises that stall a launch right as demand peaks. With DFM support and one-stop assembly, Donlly keeps consumer programs fast, cost-effective, and consistent on the shelf. A single partner across prototype and volume means the unit a reviewer buys matches the unit in the cart - no silent changes between runs that confuse support later. We also plan for the commercial side of a consumer launch: spares that match the original build, documentation your support team can trust, and a supplier still reachable when a revision ships. Donlly's single-line model means the unit you reviewed and the unit in the cart are built the same way, with the same tests - so a running change never surprises a customer or a returns desk. That consistency is what protects a brand when a product sells at volume across many channels at once. Bring us the target price and we will help you hit it through layout and component choices, not quality cuts. We keep mirror stock of long-lead parts so a hot SKU never stalls waiting on a single source.

LED and lighting products need efficient thermal paths, stable current control, and boards that hold up under constant heat and on-off cycling. Donlly builds aluminum-based and standard FR4 boards for fixtures, modules, and smart lighting with assembly tuned for the category, where thermal performance is the difference between a long-lived product and a warranty headache. Our prototyping service validates thermal layout and driver interface early, then scales into production on a line that handles SMT, THT, and mixed placement with AOI, X-Ray, ICT, and FCT. For metal-core PCBs we manage the special handling these boards require - fixturing, thermal profiling, and inspection - so yield stays high even on thermally demanding designs. We advise on heatsinking, trace width for current, and EMI for dimmable and connected lighting, and we keep process records that support field reliability. Component sourcing covers the LEDs, drivers, and controllers lighting designs depend on, so a bill of material stays buildable as parts shift. From a first sample to volume fixtures, Donlly delivers the thermal and electrical stability good lighting demands. Because thermal behavior is set at the board level, validating it in prototype and building the same way in volume protects both brightness and lifetime. We also plan for the practical side of a lighting program: spares that match the original board, documentation your service team can use, and a supplier still reachable when a fixture line needs a reorder. Donlly's single-line model means the sample you approved and the units on the line are built the same way, with the same tests - so a rerun never shifts brightness or color. That consistency is what keeps a luminaire family looking and performing the same across every batch you ship. For thermal work, share the wattage and we will size traces and recommend metal-core where it pays off.

Aerospace and defense programs demand the highest levels of reliability, documentation, and traceability. Donlly supports avionics, satellite, and ruggedized defense electronics with rigid-flex and HDI boards built to survive vibration, altitude, and wide temperature extremes - conditions where a commercial-grade board would simply not be trusted. Our rigid-flex capability removes connectors and saves weight, critical in flight, while HDI blind/buried vias pack more function into less space. Prototyping lets you prove a design before committing to a qualified run, and production assembly includes AOI, X-Ray, ICT, and functional test with full process records suitable for controlled programs. We align to IPC acceptance classes and can support the controlled, documented workflows these programs require, including component traceability and obsolescence planning for long service lives. DFM reviews reduce risk where re-work is expensive or impossible - exactly the case when a board is sealed into a system that cannot be opened in the field. From prototype to qualified production, Donlly delivers the discipline aerospace and defense work demands. One partner across the lifecycle means the controlled build you qualified is the build that ships, with the paperwork to prove it at every stage. We also plan for the unglamorous parts of a defense program: controlled revisions, retained first-article data, and a bill of material that stays sourced across a long service life. Donlly's single-line model means the prototype you qualified and the units delivered are built the same way, with the same tests - so a replenishment order never becomes a re-qualification. That continuity is what program offices count on when a platform must stay supported for a decade or more. State your acceptance class and traceability rules at RFQ and we will build the process file to satisfy them from lot one. We keep mirror stock of long-lead parts so a replenishment order never stalls waiting on a single source.
