CASE STUDIES
REAL RESULTS
Yeancheeng does more than make dies; we also work with customers to optimize their processes. Below are our actual results in die layout optimization, material automation, and quality measurement, along with a look at daily production. Every project starts from the customer's pain point, using engineering improvements to deliver substantial gains in capacity and yield. For technical details on any case, please get in touch.

ALL CASES
Capacity +20% · Die Improvement
Overcoming the limits of traditional dense layouts and insufficient structural strength, we have successfully integrated two individual 1,000+ cavity molds into a single, high-performance unit. This innovation boosts the total cavity count to over 2,500, significantly enhancing production efficiency.
Holes →2,500+ · Capacity up 20%+
Automation · Material Improvement
Previously, sheet material was prepared manually. Automated machines were introduced to switch to roll-fed production, reducing labor and improving efficiency and yield.
Labor ↓ · Efficiency↑
Full Inspection · Quality Control
Every die batch comes with a QA dimensional measurement report to ensure hole position tolerance of ±0.02mm.
Tolerance ±0.02mm · Batch-by-Batch Reports
5S · Process in Action
Performed in a clean environment, with 5S management implemented to keep quality spotless.
Temperature-Controlled Environment · 5S Management
Cleanliness · Process in Action
Before entering the work area, personnel pass through an air shower to remove particles, preventing particle contamination from affecting FPC process yield.
Dust Removal Before Entry · Particle Control
Temperature Control · Process in Action
A dedicated lamination room controls temperature and humidity to ensure stable bonding quality between adhesives and stiffener materials.
