CCL(Copper Clad Laminate)
Simulation Service
We provide a simulation service using the characteristics of a copper foil laminated plate to improve the reliability of products.Multi-Physics Simulation for mechanical analysis and electrical analysis
Doosan supports mechanical analysis of warpage and heat dissipation and electrical analysis of signal loss and impedance for semiconductor package, light emitting diode (LED), and PCB to which our products are applied.As use of smart devices including smart phones and tablet PC has increased and applications have varied recently, demand for faster processing speed and larger capacity is also increasing. The overall size of devices, meanwhile, becomes light, thin, short, and small, which could raise warpage issues. As a result, warpage issue and signal loss of substrates become important to meet customers’ requirement for fast speed processing.

Simulation service for the CCL warpage analysis of ultra thin plate PKG and PCB level
Flip Chip, POP, and MCP are widely adopted in the current semiconductor packaging process to connect chips to PCB directly using solder balls instead of WLCSP and wire. To respond to such changes in the packaging technology, Doosan CCL products have low CTE and high Tg product lines. In addition, thickness of epoxy molding compound (EMC) is reduced due to ultra-thin PKG, and density of Cu pattern has a great effect on warpage in PCB. We support the warpage simulation service using the ANSYS workbench and 3D Moire measurement that can measure PKG warpage by temperature profile.Warpage simulation service of super-thin plate PKG, PCB, and CCL
