What this manufacturer makes
Eisun Electronics manufactures high-layer-count printed circuit boards in Songgang, Shenzhen. Its official introduction dates the business to 2001 and describes applications in industrial control, communications, energy, automotive electronics, medical equipment and security. The published process sheet provides both standard and maximum production-panel dimensions, as well as a 2–32-layer range. This profile retains the metric routing figures from that sheet and avoids assuming that the largest panel, highest layer count and heaviest copper are available in one construction.
