 L/S 15µm、 L/S 20µm、L/S 25µmの比較

PMT Package Foundry is specialized in low-volume or trial production of FOWLP (Fan Out Wafer Level Package) or WLCSP (Wafer Level Chip Scale Package).
Because we use an appropriate amount of IC chip, the entire wafer is not required.
Furthermore, fine and flexible wiring is available since we produce package by using redistribution layer (RDL) technology.
We propose RDL packages with various functions such as heterogeneous integration SiP and extremely thin packages. Please feel free to contact us!

●Improvement of Signal Integrity

Reduction of electric resistance and parasitic capacitance with RDL helps better signal integrity

●Improvement of Heat Dissipation

Lower thermal resistance and better heat dissipation because of thinner package.
