Latest Patents

Among his latest patents, Kwan's work includes two groundbreaking inventions:

1. **Recessed Cavity in Printed Circuit Board Protected by LPI** - This patent describes a PCB comprising multiple stacked layers laminated together. The laminated stack incorporates regular flow prepreg and features a recessed cavity. The bottom perimeter is crafted using a photo definable, or photo imageable, polymer structure that exhibits low adhesion to an underlying conductive layer, such as an LPI mixture. This innovative design not only defines the cavity dimensions but also facilitates the integration of regular flow prepreg in the laminated stack.

2. **Self-Decap Cavity Fabrication Process and Structure** - This invention also focuses on PCBs with multiple stacked layers laminated together. Similar to his previous patent, it includes a recessed cavity, where the bottom perimeter is defined by a photo definable or photo imageable polymer structure, such as a solder mask frame and protective film. This design protects inner core circuitry at the bottom of the cavity during fabrication while enabling the utilization of regular flow prepreg in the laminated stack.
