Patent number: 11495525Abstract: A module has electronic components mounted to a Printed Circuit Board (PCB) with multiple patterned conductive layers connecting to conductive slot metal around a conductive slot. A groove is cut through a top molding encapsulant above and into the conductive slot but does not cut through a bottom molding encapsulant. A terminal pin is inserted into the groove and pushed down into the conductive slot. When heated, embedded solder previously applied to the conductive slot metal flows between the end of the terminal pin and the conductive slot metal to form a solder bond. An end of the PCB past the conductive slot has no metal traces, preventing shorts. Epoxy can be placed into the groove around the terminal pin or a hole formed in the terminal pin to increase strength of the anchored terminal pin. The molding around the groove protects terminal pins from shorting from the side.Type: GrantFiled: March 3, 2021Date of Patent: November 8, 2022Assignee: Hong Kong Applied Science and Technology Research Institute Company LimitedInventors: Lourdito M.
