Understand MLCC and Passive Component Automatic Dipping Machines: Principles, Productivity, and Industrial Applications
In modern electronics manufacturing, precision, efficiency, and reliability are critical for success. Among essential processes in MLCC (Multilayer Ceramic Capacitor) and passive component production, automatic dipping machines play a pivotal role in applying conductive paste to chips. Leveraging these machines ensures consistent quality while supporting scalable, high-volume production.
How Automatic Dipping Machines Work in Passive Component Production
Automatic dipping machines are engineered to deliver uniform and controlled dipping of conductive paste onto passive components such as MLCCs, chip resistors, and inductors. The process begins when components are loaded into Thin Carrier Plates (TCPs) and guided to the dipping station via precise motion control.
Key Steps in Automatic Dipping
- Alignment and Handling
Components are accurately positioned in TCPs, ensuring repeatable and precise dipping. - Dipping and Withdrawal
Controlled height and speed maintain consistent conductive paste thickness, critical for reliability. - Vacuum Debubble Function
Removes trapped air bubbles to prevent defects of the conductive layer. - Drying
Dipped chips are dried before unloading to secure the conductive paste for downstream processes.
This controlled workflow reduces variation, enhances reliability, and improves overall product quality. Compared to manual dipping, automatic dipping machines enable manufacturers to achieve high-volume production with minimal defects.

Measuring Dipping Productivity: Beyond Speed
For production managers, understanding how to calculate productivity is essential in evaluating and comparing dipping systems. In passive component manufacturing, productivity is measured in pieces per hour (pcs/hour), factoring in throughput, yield, and process efficiency.
Productivity Formula for Automatic Dipping Machines
Productivity = (Number of chips per cycle ÷ Cycle time ÷ 2 sides) × Yield rate
- Number of chips per cycle: Determined by chip size and TCP capacity
- Cycle time: Influenced by dipping cycle duration
- Yield rate: Percentage of defect-free outputs
Example:
If one TCP holds 18,128 pieces of 0402 (1005mm) chips, and the dipping cycle time is 40 seconds with a yield rate of 99%:
18128 ÷ (40 × 2) × 60 × 60 × 0.99 = 807,602 chips per hour
This demonstrates that productivity depends on balancing throughput with quality. Optimizing cycle time, dipping uniformity, and yield ensures maximum equipment effectiveness (OEE).
