Mechanical Switch Buffer Daughter Board

@miguelcen64

Hi, I can design the tiny daughter board for your mechanical switch buffer with the single-sided assembly constraint in mind. I’ll keep all components and solder tabs on one side, avoid underside holes/traces, and prepare fabrication-ready output for JLCPCB: Gerbers, BOM, and Pick & Place files. I’ll also review the provided schematic and flag any issues if I see a better way to handle the P-MOSFET current path, switching behavior, or 0-5V input range. My focus will be on a clean, manufacturable layout that matches your size and assembly requirements. If you’d like, I can start by confirming the footprint strategy and stackup assumptions from the attached schematic, then move straight into the PCB layout. Best, Miguel

With my engineering background and experience, I’m the ideal fit for this job. Not only am I comfortable with circuit design and electronics, but I also understand the importance of longevity in manufacturing - an aspect that you need taken care of with the design suitable for JLCPCB. I'll strategize the design to maximize current carrying capacity via P-MOSFET within your specified input voltage range while ensuring all solder tabs and components are meticulously placed on one side, without affecting the underside. One of my strengths is the capacity to analyze a pre-existing schematic effectively. I'll carefully review your existing circuit schematic as requested, critiquing and proposing improvements, if necessary. It's crucial to me that I meet your requirements while employing problem-solving skills to optimize performance and ensure optimal production yield. Not only will my grasp on PCB layout design deliver top-notch files but also provide buildable layouts with Gerber files, BOMs and Pick & Place files that are hassle-free for JLCPCB Manufacturing. Trust me with your project, satisfaction is guaranteed!
