Decoding legacy hardware, cloning obsolete boards, and innovating custom electronic solutions from concept to production.
Legacy systems are the backbone of many industries — from industrial automation and defense systems to medical equipment and telecommunications infrastructure. When these critical systems require replacement boards, the original manufacturer may no longer exist, documentation may be lost, and the original components may be obsolete. PCB Reverse Engineering solves this problem by meticulously decoding the physical hardware back into fully documented, manufacturable design files.
At SMTWISE Technology, our reverse engineering process goes far beyond simple board copying. We analyze circuit logic, identify component functions, trace signal paths across multiple layers, and generate complete schematic diagrams that accurately represent the original design intent. This deep understanding allows us to not just reproduce the board, but to upgrade it — replacing obsolete components with modern equivalents, improving performance, and extending the product lifecycle by decades.
Why choose SMTWISE? We don't just copy circuits — we understand them. Our engineers analyze the design intent behind every circuit block so we can guarantee the cloned board performs identically to (or better than) the original, even with modern replacement components.
Whether you're ordering from our reverse engineering output or submitting your own designs, a complete fabrication package should include:
End-of-Life (EOL) and obsolete components are a constant challenge in electronics manufacturing. A component that was readily available when your product was designed may become unavailable months or years later due to manufacturer discontinuation, technology shifts, or supply chain disruptions. Our proactive approach includes:
Turn your concept into a production-ready product. Our dedicated R&D engineering team works alongside you to design, prototype, test, and iterate custom hardware solutions from the ground up. Whether you need a new IoT sensor board, a power management module, or a complete embedded computing platform, we have the expertise and equipment to bring it to life.
Our PCB design team uses industry-leading tools including Altium Designer, KiCad, and Eagle to create optimized board layouts. We specialize in high-density interconnect (HDI) designs, controlled impedance routing for high-speed signals, mixed-signal layout with proper analog/digital isolation, and RF/microwave circuit design up to 40GHz.
Proper PCB layout is critical for signal integrity, EMI compliance, thermal management, and manufacturability. Our designers follow rigorous layout rules including:
A DRC (Design Rule Check) verifies that your layout meets the minimum geometric constraints defined in your design rules — trace width, spacing, annular ring, etc. A DFM (Design for Manufacturing) review goes much further, evaluating your design against the actual capabilities and limitations of the fabrication and assembly processes. DFM catches issues that a DRC cannot — such as acid traps, copper balance problems, thermal relief violations, and assembly access constraints.
Before layout begins, the schematic must be thoroughly reviewed for correctness. Key schematic design rules include: proper power and ground symbol usage, consistent net naming conventions, ERC (Electrical Rule Check) verification, decoupling capacitor placement for every power pin, proper termination of unused IC pins, and complete pin-to-pin connectivity verification.
Our embedded engineers develop firmware for microcontrollers (STM32, ESP32, PIC, AVR), FPGAs (Xilinx, Intel), and application processors (ARM Cortex-A). Services include bootloader development, RTOS integration (FreeRTOS, Zephyr), wireless protocol stacks (BLE, Wi-Fi, LoRa, Zigbee), sensor driver development, and over-the-air (OTA) update systems.
Design for Manufacturability (DFM) rules ensure your PCB design can be reliably and cost-effectively fabricated. Critical DFM considerations include:
We frequently encounter design issues that cause unnecessary delays and cost overruns. The most common mistakes include:
Free DFM Review: We offer complimentary Design for Manufacturability review on every order. Upload your Gerber files and we'll identify potential issues within 24 hours — before they become expensive production problems.
Our prototyping lab delivers assembled boards in as few as 48 hours for urgent design validation cycles. We also provide 3D-printed enclosure prototypes to verify mechanical fit, connector access, and thermal performance before committing to injection mold tooling.
