Engineering solutions are proven where projects get difficult

A single PCBA required three different conformal coatings in separate zones along with underfill, extremely low volume, and stringent reliability requirements for extreme environments

Precision selective coating process combined with proactive validation of alternative material options to reduce material risk and shorten validation cycles while maintaining reliability

Stable continued delivery with deeper customer trust

Original design engineer had departed and only a test requirements checklist remained; A universal test system compatible with multiple control boards was needed urgently

Analyzed interface behavior and rebuilt the test logic, independently completed hardware design (power system, command simulation, signal acquisition), iterated firmware through multiple versions, and developed PC software in parallel

Delivered in under three months; one test system supports multiple control boards; Client continues to choose Ledge for new projects

Critical display module was discontinued by the supplier; product delivery had been delayed for six months with no special supply arrangement available

Proactively sourced medical and industrial-grade OLED alternatives, designed a fully compatible driver board requiring only minor firmware adjustments from the client, completed prototype validation in 6 weeks with no minimum order quantity

Supply chain crisis fully resolved; modular design supports future screen upgrades
