PCB Layout Jobs

I have a complete schematic ready and now need it translated into a production-ready multi-layer PCB. The board will carry a mix of high-speed signals and power lines, so careful layer stacking, impedance control, and good grounding practices are critical. You’ll start from my annotated schematic (PDF + native CAD format) and component datasheets. I’ll also share form-factor constraints and the connector placement I must keep. From there, I expect: • Clean, rule-checked PCB layout in the CAD tool you normally use (Altium, KiCad, or Eagle are all fine). • Gerber/ODB++ files, drill files, and pick-and-place data prepared for fabrication. • Source CAD files so I can make future edits. • A concise design report summarising layer stack, controlled-imp...

I need complete Gerber files for a multi-layer printed circuit board that will be built on six layers. The schematic is ready; what I’m missing is a clean, production-ready Gerber package that a board house can use without further tweaks. Here’s what I expect: • Layer stack-up defined and documented • Drill files, solder mask, paste mask, silkscreen, and assembly drawings included • All outputs checked against standard DRC rules and CAM verified before hand-off If you normally work in OrCAD, or similar professional tools, that’s perfect—just let me know which platform you prefer so I can provide compatible source files. Turnaround time and any questions about the stack-up or manufacturing constraints are open for discussion; I’m look...

I need three compact electromagnets fabricated for integration into a larger prototype. Final outside dimensions will be supplied once we begin, but each unit must: • Run from a standard low-voltage DC source (anywhere in the 12–24 V range is acceptable). • Provide variable holding force up to 40 N, adjustable via a simple in-line control such as PWM, current-limit circuit, or potentiometer. • Remain within the specified footprint and include straightforward mounting points so I can drop them straight into my assembly. • Operate continuously without excessive heat build-up or noticeable magnetic drift. Deliverables • 3 fully wound and assembled electromagnets built to the agreed dimensions • Matching driver or control interface with wiring diagram an...

I’m building a compact diagnostic tool for battery and need a production-ready PCB to bring the project to life. Because I’m still weighing single-, double- or multi-layer construction, I’m relying on your expertise to propose the most efficient stack-up once you’ve seen the schematic and performance goals. The board must accommodate power regulation, signal capture, and a USB-C interface while staying small enough for a handheld enclosure. I’ll provide a full instruction as working prototype in my hand and preferred parts list; you’ll translate that into clean, manufacturable design data that any mainstream fab (JLCPCB, PCBWay, etc.) can run without extra tweaks. Deliverables • Editable design files in KiCad • Gerbers, drill files, pick-an...

I need a surface-mount power-supply board designed for a consumer-electronics product. The board will run directly from 220–260 V AC and must deliver a regulated 144 V DC at 300–350 mA. Reliability is critical, so the design has to meet a 6 kV surge requirement, include both high- and low-voltage protection, and achieve a high power factor. I already know the exact outer dimensions for the PCB and will forward the drawing as soon as we start; everything has to fit inside that footprint. Apart from those limits, component placement is up to you. I’m leaning toward standard FR-4, but I’m open to alternatives if you see a clear advantage. Please supply the complete schematic, PCB layout, Gerber files, an annotated BOM with part numbers available from major distributo...

I’m developing a compact, aluminium-clad SMD PCB that will live directly on mains, so every detail must be right first time. The board sits on 1 mm aluminium with 25 µm copper, accepts 220-260 VAC and has to deliver a rock-solid 144 VDC at 300-350 mA. Power-factor must stay high thanks to a hybrid DOB topology, while the protection network must survive 6 kV surges and automatically cut in on both high- and low-voltage events. Everything must be RoHS-compliant. Because the board ultimately feeds a power-supply module, thermals and creepage/clearance are just as critical as the electrical design. I’m looking for a clean, production-ready package that lets me hand Gerbers straight to my fabricator and have parts placed with confidence. Deliverables • Complete schema...

I am building a battery-powered edge node around the STM32WL (LoRa-E5 module) that must sit in the field for years on a single 5 000 mAh cell. To reach that target I need both the hardware design and the accompanying firmware created with an obsessive focus on nano-amp sleep currents and efficient duty-cycling. Core capabilities • Data logging to internal flash or external EEPROM so records are retained between wake-ups. • LoRa communication only; no Bluetooth or Wi-Fi. The node will periodically wake, send an uplink, accept a downlink if present, and return to deep sleep. • Simple sensor block: one digital interrupt input (e.g., reed switch/pulse counter) plus one digital output that can drive an external load for a short, timed burst. Hardware scope – Compl...

I need a custom-shaped, single-layer printed circuit board produced quickly so I can test the mechanical fit and basic electrical routing for a new product I am developing. The overall board must stay as thin as practical; once we speak I will confirm exact thickness and any stack-up limits from my enclosure, but the goal is to minimise profile without sacrificing manufacturability. Here is what I will supply once we start: • A rough outline drawing and simple netlist showing the required connections • Components and preferred connector locations What I expect from you: • Review of my outline and placement to flag any manufacturability concerns • At least three fabricated prototypes shipped to me for bench testing Please use whichever professional tools you a...

I already have step-by-step build notes for a tactile glove and the preliminary PCB design files. What I now need is practical help getting that board fabricated through PCBWay. Your job is to take my PCB files, carry out any touch-ups they still require—basic DRC fixes, panelisation or drill map tweaks—then upload the finished Gerbers and BOM to PCBWay, configure the order and place it. The glove relies solely on sensors, with pressure sensors and flex sensors called out in the documentation, so please double-check that the footprints and connector pinouts for those parts remain intact throughout your edits. Deliverables I expect: • Cleaned, production-ready Gerber, drill and pick-and-place files • Updated BOM highlighting the pressure and flex sensors used &bull...

I’m inviting a handful of practicing hardware engineers or PCB designers to spend about 15 minutes inside my pre-launch web app, PartPilot (). Upload a BOM or punch in a part number, then tell me—straight, no sugar coating—what keeps this from becoming a tool you’d lean on every day. During my own testing, the ability to see stock information across four distributors in one glance feels like the killer feature, but I need fresh eyes. Point out what’s confusing, what’s missing, and what would make you actually pay for Pro. How this works • You must have real-world PCB experience; KiCad users are ideal, though Altium or EasyEDA is fine too. • Reply with a line or two about your experience designing boards or managing component sourcing. No ...
