Abstract
A chip scale LED packaging method includes the following steps: clamping an upper mold with a plurality of through holes and a plate-shaped lower mold together; allowing bottoms of the plurality of through holes of the upper mold to be sealed by the plate-shaped lower mold to form a pattern of a plurality of grooves; placing chips one by one in corresponding through holes of the plurality of through holes; pouring encapsulation gel into each of the corresponding through holes; separating the upper mold from the plate-shaped lower mold after the encapsulation gel is cured and molded; and separating each cured and molded encapsulation gel from each of the corresponding through holes of the upper mold and taking each cured and molded encapsulation gel out of the upper mold to obtain an individual chip scale LED package.
