# PCB design and electronics design services | OneStack > Electronics and PCB design services from Brescia, Italy: schematic and layout up to 12 layers, HDI, rigid-flex, EMC. Proposal in 48 hours, guaranteed dates. URL: https://www.onestack.it/en/pcb-design ![](/_astro/pcb-sonda.BddQthig_zo5Er.webp) Service · PCB design # From schematic to tested board, on guaranteed dates We design high-reliability electronic boards for mission-critical systems in industry, defence and harsh environments, from architecture to manufacturing files. For companies that need to speed up a project, replace an obsolete board or have no in-house design team. From our lab in Brescia, Italy, with prototypes assembled and tested in-house. [Proposal in 48 hours](/en/contact) ## What we do ### Architecture and component selection Block diagram, choice of microcontroller, power supplies and key components, checking availability, lifecycle and alternatives across distributors. ### Schematic design Analog, digital, power and interfaces. Simulation of critical circuits and review before layout. ### Multilayer layout Boards up to 12 layers, HDI and microvias, rigid-flex, impedance control and design rules agreed with the PCB fab. ### Design for EMC, manufacturing and test Stackup, ground planes, filtering and protection designed for EMC testing; footprints, panelisation and test points designed for the assembler and for production test. ### Redesign and obsolescence Replacing end-of-life parts, redesigning existing boards for long-lifecycle products, reducing BOM cost. ### Prototypes and bring-up We assemble prototypes in-house, power them up and check power rails, signals and interfaces in our lab. ## Capabilities - Boards up to 12 layers, HDI, rigid-flex - Switching and linear power supplies, power electronics, motor control - Industrial interfaces: CAN, RS-485, Modbus, Ethernet, USB - Board-level security: protected debug, secure element, memory for secure updates - Radio: BLE, Wi-Fi, LoRaWAN, UWB, GNSS - Analog and measurement front-ends - Design for harsh environments: vibration, extreme temperatures, conformal coating, long-life components - Design to IPC-2221, assembly to IPC-A-610 ## Tools and technologies ### ECAD and simulation - Altium Designer - KiCad - SPICE ### Critical interfaces - DDR - USB - Ethernet - RF and antennas - CAN - RS-485 ## What you get - ECAD source project (schematic and layout) - Gerbers, drill files, stackup and fabrication drawings - BOM with distributor part numbers and alternatives - Pick-and-place files and assembly drawings - Assembled and tested prototypes, with a test report ## Lead times A new project starts with a feasibility study, delivered in 72 hours, which becomes the requirements specification; for complex projects the duration of the study is written in the proposal. If the specification already exists, we skip the study and the proposal covers the project itself, with delivery dates. technical answer from an engineer 24 hours proposal for the feasibility study 48 hours board design 2 weeks working, tested prototype 4 weeks Typical lead times from the order, with an approved requirements specification, standard complexity (up to 6 layers) and parts in stock. For more complex projects the dates are written in the proposal. ## Electronics projects [ ![3D render of the control board: microcontroller in the centre, connectors for the two isolated channels on the side, pluggable terminal blocks and power and service connectors](/_astro/interfaccia-rugged.CkQk4iYb_1A6Ozp.webp)![](/_astro/interfaccia-rugged-xray.CZb6dpZZ_Z1kxhOu.webp) 23 tests in ~75 s Systems for harsh environments ### A rugged interface that updates in the field and never bricks A portable, battery-powered unit that powers and controls two remote devices over isolated channels. The hard part was making it reliable far from any lab. Its firmware updates in the field and, if something goes wrong, rolls back on its own to the last working version.

We found out before building it A bench that tells in seconds whether an electric-field sensor works, measuring capacitances of a few picofarads in air. The method planned at the start was ruled out with measurements, before any money went into hardware.

It depends on complexity, layer count, radio and power. Within 48 hours we send you a proposal: for a new project it covers the feasibility study, which sets architecture, risks and specification; if the specification already exists, it covers the project itself, with costs and delivery dates in writing. Can you start from an existing schematic or board? Yes. We take over existing designs, fix them, update them or replace obsolete parts. Do you sign an NDA? Yes, even before we see your files. Do you handle series production? We prepare everything for the assembler (files, test, documentation) and support the transfer to production with EMS partners. ## Got a deadline? Tell us about your project: within 48 hours you get a proposal with phases and dates. If needed, we sign an NDA before seeing your files. [Request a proposal](/en/contact)[Urgent?
