What this manufacturer makes
Liandajin Electronics is a Huizhou printed circuit board manufacturer whose company history dates to 2005. Its process information covers single-sided through 20-layer boards and lists FR-4 alongside high-frequency and metal-base materials. The technical table provides separate values for panel size, routing, copper and impedance. These are individual published process capabilities, rather than a promise that every extreme is available on one board. Material identification and the proposed stack-up remain essential to an engineering review.
