New Product Introduction (NPI)
At WELLER, our seasoned New Product Introduction (NPI) specialists utilize production-equivalent processes from prototype through volume manufacturing. This approach enables:

  • Early identification of design/manufacturing challenges
  • Comprehensive design validation
  • Seamless transition to full production

We recognize the critical importance of speed-to-market and offer accelerated prototyping services without compromising quality or manufacturability.

Software & Firmware Development

We provide professional firmware programming and debugging solutions for embedded systems. Using industry-standard tools (JTAG, SWD, ICSP), we ensure accurate firmware burning onto MCUs, SoCs and FPGAs. 

Our debugging services cover real-time tracing, protocol analysis (UART/I2C/SPI), and hardware-level troubleshooting to resolve memory leaks, timing issues and boot failures. We support compliance with IPC and ISO standards, delivering reliable performance for IoT, industrial and automotive applications.
