How Are MLCCs Made?
MLCCs (Multilayer Ceramic Capacitors) are vital in electronics, and their production involves precise steps. Let’s explore the key stages, including insights from Dongguan Hehongyang Electronic Technology Co., Ltd.
1. Raw Material Prep
1.1 Selecting Core Materials
MLCC production starts with ceramic powders (e.g., barium titanate) for dielectrics and metal powders (nickel, copper) for electrodes. Purity is critical for performance.
1.1.1 Powder Processing
Ceramic powders are ground to fine, uniform sizes to enable thin dielectric layers, boosting MLCC capacitance in small packages.
1.1.1.1 Mixing for Pastes
Powders are blended with binders/solvents to form dielectric and electrode pastes, ensuring smooth application.
1.1.1.1.1 Paste Viscosity Control
Proper viscosity ensures even coating, a key step for consistent MLCC quality.
2. Layer Formation
2.1 Tape Casting
Dielectric paste is spread into thin tapes (micrometers thick) using a doctor blade, then dried.
2.1.1 Printing Electrodes
Internal electrodes are screen-printed onto tapes in patterns that align when stacked, forming parallel capacitors in the MLCC.
3. Stacking & Laminating
3.1 Precise Stacking
Tapes are layered with alignment accuracy to avoid defects. More layers mean higher MLCC capacitance.
3.1.1 Bonding Layers
Stacks are pressed under heat/pressure to form a solid block, critical for MLCC integrity.
4. Cutting & Sintering
4.1 Cutting Blocks
The block is sliced into individual MLCC units using diamond tools for precision.
4.1.1 Sintering
Units are heated to high temps (over 1000°C) to fuse ceramics and bond electrodes, strengthening the MLCC.
4.1.1.1 Atmosphere Control
Reducing atmospheres protect metal electrodes, a step Dongguan Hehongyang Electronic Technology Co., Ltd. masters with advanced furnaces.
5. External Electrodes
5.1 Applying Connections
Ends are dipped in conductive paste (silver, tin) and plated (nickel/tin) for solderability, completing the MLCC’s circuit link.
5.1.1 Quality Checks by Dongguan Hehongyang
The company tests MLCCs for capacitance, insulation, and durability, ensuring top performance.
6. Packaging
6.1 Final Steps
Approved MLCCs are packaged in reels/trays for safe delivery, ready for electronics assembly.
