Samsung patents method for making display light sources with solder bridges
Samsung describes a manufacturing process for a light source device used in displays. The method involves creating two substrate layers with alternating bars, connecting them with bridges, and using a mask to guide solder into specific openings to secure the components.
In the filing’s own words
There is provided a method for manufacturing a light source device including a first light source substrate and a second light source substrate, the method including: forming, in a base substrate, the first light source substrate including a first substrate body, extending in a first direction, and a first substrate bar extending from the first substrate body in a second direction; forming, in the base substrate, the second light source substrate including a second substrate body, extending in the first direction, and a second substrate bar extending from the second substrate body in a third direction opposite to the second direction and disposed alternately with the first substrate bar; forming bridges connecting the first light source substrate and the second light source substrate; disposing, on the base substrate, a mask pattern including an opening; disposing a solder on the mask pattern; and introducing the solder into the opening.
What exactly they claim (claim 1)
1. A method for manufacturing a light source device comprising a first light source substrate and a second light source substrate, the method comprising: forming, in a base substrate, the first light source substrate comprising a first substrate body, extending in a first direction, and a first substrate bar extending from the first substrate body in a second direction; forming, in the base substrate, the second light source substrate comprising a second substrate body, extending in the first direction, and a second substrate bar extending from the second substrate body in a third direction opposite to the second direction and disposed alternately with the first substrate bar; forming, by a cutting of the base substrate, a plurality of bridges connecting the first light source substrate and the second light source substrate, the first substrate body of the first light source substrate and one end of the second substrate bar of the second light source substrate in the third direction are connected by the plurality of bridges; disposing, on the base substrate and after the cutting the base substrate, a mask pattern comprising an opening; disposing a solder on the mask pattern; and introducing, by a pressing of the solder on the mask pattern, the solder into the opening.
