Manufacturing Artistry
The Essence of the Lamination Process
Multilayer board lamination is a precise science. Topfast employs “progressive temperature-pressure control” technology, with precise control across 32 temperature zones, ensuring interlayer bonding strength reaches over 18N/cm². Dedicated lamination solutions have been developed for different layer structures:
| Board Layer Type | Lamination Structure | Temperature Curve | Pressure Control |
|---|
| 6-8 Layer Boards | Symmetrical Balance | Three-Stage Heating | Progressive Loading |
| 10-16 Layer Boards | Stepped Distribution | Five-Stage Heating | Multi-Stage Voltage Stabilization |
| 20+ Layer Boards | Modular Combination | Seven-Stage Heating | Intelligent Adjustment |
