Hi, Your NFC/secure element module sounds like a great fit for what I do — I design compact multilayer boards for a living, and this one has all the tricky parts I actually enjoy: tight NFC antenna tuning, secure MCU routing, and squeezing everything into an HDI board that connects to your phone's PCB. A couple of things worth flagging early since they'll shape the design: The NFC antenna will need to be tuned around the final board placement, and kept away from the vibrator motor and any metal in the housing — that's usually where compact NFC modules run into range issues if it's not planned from the start. Given the part count (NFC, secure element, secure MCU, USB-C, vibrator, touch buttons, pogo pins) in a small footprint, I'm expecting we'll need a 6-8 layer HDI board with microvias. I'll confirm once I see your size constraints. I'll handle everything from schematic through PCBA — schematics, PCB layout with Gerbers/drill files/3D model, BOM with backup parts, and a short report on signal integrity and manufacturability. Once you send over your smartphone PCB's BOM and interface details, I can get started on a block diagram. Would also help to know your target secure MCU/element if you already have one in mind, and the pogo pin current rating. For payment, I'd suggest splitting it into milestones — schematic, layout, then PCBA/final files — but happy to do hourly if that works better for you. Let me know what you think.

Hi, I can design your compact HDI multilayer PCB from schematic through manufacturing-ready PCBA files, with special attention to NFC antenna performance, secure components, USB-C routing, and smartphone-level space constraints. I understand this board needs to interface reliably with your existing smartphone PCB, so the first step will be reviewing the main PCB BOM, available interfaces, mechanical dimensions, power rails, and connector requirements. I can handle: 1. Schematic design and component selection 2. Secure MCU and secure element integration 3. NFC circuitry and custom NFC antenna design/tuning 4. USB Type-C data interface with ESD protection 5. Vibrator driver and touch-button circuitry 6. Pogo-pin charging interface 7. Compact HDI multilayer PCB layout with controlled impedance, via-in-pad/microvia strategy where required 8. DFM/DFA checks and complete Gerber, drill, BOM, pick-and-place, and assembly documentation For a smartphone-sized board, antenna placement, grounding, EMI, power integrity, and mechanical stack-up need to be considered together rather than treating this as a standard PCB layout. Once you share the main PCB details and target dimensions, I can review the architecture and recommend the appropriate layer count and HDI stack-up. Can you share the approximate available PCB dimensions and how the custom board will connect to the existing smartphone PCB?

Hi, I reviewed your requirements for the compact multilayer board that will interface with your existing smartphone PCB. I understand that the new board needs to integrate NFC with a custom antenna, a secure element and secure MCU, USB-C for data, vibration control, touch inputs, and pogo-pin charging while keeping the overall design highly compact. I can handle the schematic and PCB development and prepare the manufacturing/assembly files. Before starting the layout, I would first review the existing smartphone PCB interface, mechanical dimensions, available power rails, communication interfaces, and your preferred secure MCU/secure-element architecture. For the NFC section, particular attention will be required for antenna geometry, placement, matching/tuning provisions, and isolation from surrounding electronics and the smartphone assembly. I work with KiCad and Altium and can prepare the design with manufacturing constraints considered from the beginning. Please share the available board dimensions, interface requirements, and main-board documentation so I can review the architecture before finalizing the scope. Best regards, Hamza
