@AITSoft

Hello, I understand you need a reliable reproduction of your dual-channel, 80 A DC reverse controller board from just photos and hardware. My plan is to carefully study the images you provide to extract exact dimensions and circuit details, then rebuild the schematic into a clear, single-line diagram showing the dual high-current H-bridge structure. I’ll recreate the PCB layout preserving original footprint and mounting points, making sure the copper pours and routing suit high current safely. I'll find exact or modern replacement components to ensure long-term supply, and produce full manufacturing files like Gerbers, pick-and-place, and centroid for straightforward ordering. Given the importance of thermal and electrical performance, I'll focus on solid high-current design and protection features, so your prototype runs smoothly at full load. What are the exact dimensions or scale references from the photos for the board and key components? Thanks,

Hello, This is a solid reverse-engineering task involving a high-current dual-channel H-bridge controller. I have strong experience in reconstructing schematics and PCB layouts from board images and legacy hardware. I will extract the full circuit, including power stage, gate driving, and protection elements. Special focus will be on 80A current paths, copper thickness, thermal relief, and safe trace/pour design. I will redesign the PCB to match original form factor while improving reliability and manufacturability. Obsolete components will be replaced with in-production equivalents with verified availability. Gate drive timing, flyback paths, and protection (TVS, snubbers) will be carefully validated. You will receive full schematic, PCB, Gerbers, BOM, and Pick & Place files ready for fabrication. Design will be prepared to pass DFM and handle continuous industrial load conditions. I am experienced in power electronics and rugged industrial PCB design. Ready to start immediately and iterate until successful 80A validation.

Hi there, I carefully read your project description, and it fits very well with my experience in reverse engineering, high-current PCB design, and industrial electronics. I can help you recreate your dual-channel 80 A DC reverse controller into a clean, modern manufacturing package that preserves the original footprint and functionality while making it ready for reliable production again. My approach is methodical and manufacturing-focused: I reconstruct the circuit clearly, identify obsolete parts and suitable modern equivalents, preserve the mechanical constraints, and prepare clean fabrication outputs that a modern board house can use directly. I also pay close attention to thermal paths, copper sizing, protection design, and long-term reliability so the recreated controller is not only functional, but robust. I’m confident I can handle this efficiently and professionally. Feel free to send me a message so we can review the photos and get started. Best regards, Samuel Tshibangu

Hi, I’m a senior PCB design engineer with 10+ years of experience in high-current power electronics, including H-bridge motor controllers up to 120 A continuous; I have successfully reverse-engineered and reproduced 15+ legacy boards with 100% functional equivalence and improved thermal performance by up to 25%. I reviewed your images: the design clearly uses a dual-channel H-bridge with heavy busbars, relay-based switching, and a mixed control/power PCB—this is well within my expertise in industrial motor control systems. Approach ✅ I will extract the full schematic by combining visual tracing, net continuity reconstruction, and component identification (including relay logic, current paths, and protection circuits). ✅ I will rebuild the schematic in KiCad(EasyEDA, Altium, etc) with validated equivalents for obsolete components and simulate critical paths (gate drive, flyback, current handling). ✅ I will design a high-current PCB with optimized copper pours, via stitching, and busbar integration to safely support ≥80 A continuous current. ✅ I will deliver a complete manufacturing package (Gerber, BOM with sourcing, centroid, and PnP) verified against DFM/DFA standards. Questions ✅ What is the input voltage range and motor current (especially stall current)? ✅ Should the busbar layout stay exactly the same, or can it be improved? ✅ What are the operating conditions (temperature, environment)? Best, Yaroslav
