PCB Design Services: From Schematic to Production-Ready Layout
A board that works on the bench can still fail at the factory. Missing test points, tight tolerances or an unclear BOM turn a finished layout into weeks of EMS questions, losses and a second revision.
Promwad's PCB design services cover schematic capture, component selection and layout for analog, digital and mixed-signal boards. You get DFM-ready documentation your manufacturer can put straight into production.
What's Included
Schematic design and component selection
From block diagram to schematic, with parts checked for lifecycle status and availability, and a BOM that lists approved alternates.
PCB layout
From two-layer boards to multilayer HDI designs with BGA packages, blind, buried and microvias. Mixed-signal partitioning, high-current routing and thermal vias are part of the job.
3D model and enclosure fit
A STEP model of the board goes to the mechanical team early, so clearances, connectors and mounting are resolved before layout is frozen. Enclosure design →
DFM, DFA and DFT
Layout rules matched to your manufacturer's capabilities, assembly-friendly placement, and test access for ICT and JTAG.
Documentation and handoff
An IPC-compliant package for PCB fabrication and assembly, plus help selecting and briefing an EMS partner.
Need margins confirmed by simulation? See SI / PI / thermal analysis →
Start with one board and scale into full custom hardware development, from enclosures to complete platforms.
Designed Around Your Product. Built for Production
DFM, DFA and DFT decisions are made during layout, when they cost nothing to change. Here is what each one protects.
| Practice | What it prevents |
| Design for Manufacturing (DFM) | Fabrication rejects, tolerances your PCB supplier can't hold, higher unit cost |
| Design for Assembly (DFA) | Placement errors, solder defects, manual rework on the line |
| Design for Testing (DFT) | Boards that can't be covered by ICT or JTAG, faults that reach the customer |
Redesign of boards already in production
Not every project starts from zero. We take over existing designs when a component goes end-of-life, when cost has to come down for the next volume tier, or when yield or EMC problems appear in production. We review your current documentation and define the smallest change set that fixes the problem.
How a PCB Project Runs
Boards with multi-gigabit interfaces follow our extended high-speed design procedure, with pre- and post-layout analysis.
What You Receive
| Package | Contents |

| Assembly | BOM with approved alternates, pick-and-place file, top and bottom assembly drawings, stencil data |
| Design source | Native project files (Altium, PADS or KiCad), schematic PDF, 3D STEP model |
| Test | Test point map and ICT/JTAG access notes |
PCB Design Case Studies
Speed Limiter for Any Electronic-Throttle Vehicle
Automotive · NXP S32K118 · Certification-ready design
Pain. Car-sharing startup Voovoo needed a plug-and-go device that keeps a car at the current road speed limit. It had to work on any vehicle with an electronic throttle, without changing the ECU.
Solution. We designed a board on the NXP S32K118 automotive MCU that sits between the accelerator pedal sensor and the ECU and feeds it generated analog values. A shutdown path runs in hardware, independent of the microcontroller, and an SOS button passes the pedal signal straight through. Firmware and a PC configuration tool completed the scope.
Result. A certification-ready design aligned with the EU General Safety Regulation 2019/2144. With our documentation, the client moved to product certification before mass production.
Compact mmWave Radar Module for Video Surveillance
Industrial security · TI IWR6843 · Custom FR4 antenna array
Pain. A European video surveillance supplier for small industrial sites was losing the battle with false alarms. Fog, headlight glare and animal movement produced more alerts than operators could handle.
Solution. We designed a compact radar module on the TI IWR6843 with a custom antenna array on standard FR4. Radar data is processed on the board, and the module connects to the client's existing video management system through a standard interface, with no changes to the camera fleet.
Result. Working together with the cameras, the module drives false alerts to near zero and cuts operator workload by 70%.
What Our Clients Say
“Promwad completed the client's radio-electronic components research, schematics, schema, PCB design, and more. Their agile project management methodology impressed the client. The team was also flexible and has excellent leadership abilities.”
“Promwad has done a great job of managing their part in our projects. We've done 20–25 purchase orders, and worked on several projects with them. […] Their main strength is that they offer all the skills we need, such as mechanical design, firmware and software development, PCB layout, and schematic generation.”
