1.Background Overview
A client from Europe, engaged in the development of industrial automation systems, required integration of a high-precision pressure sensor module in their next-generation process control system. The module needed to detect subtle changes in gas or liquid pressure in real time to enable dynamic control and safety alerts.
Given the complex environment in which the equipment would operate, the client emphasized strict standards for PCB heat resistance, soldering reliability, and circuit stability.
KKPCB was selected as the PCBA manufacturing partner for this project due to our rich experience in industrial control applications and our proven ability to deliver high-reliability solutions.
Industry: Defense Electronics
End Applications:
Armored vehicle main control units
Field communication relay equipment
Manufacturing Challenges:
