摘要： A wiring board manufacturing method includes: forming a first groove structure in a first principal surface of a base by scanning with laser light in a first irradiation pattern such that the first groove structure has a first width; irradiating an inside of the first groove structure with laser light in a second irradiation pattern that is different from the first irradiation pattern to form recessed portions inside the first groove structure; and forming a first wiring pattern by filling the first groove structure with a first electrically-conductive material to form a first wiring pattern whose shape matches with a shape of the first groove structure in a top view.

摘要： A method of manufacturing a light emitting device including: forming grooves by removing a portion of a first resin of a first light emitting structure 100A including a first light emitting element 110A and the first resin, a portion of a second resin of a second light emitting structure 100B including a second light emitting element 110B and the second resin, and a portion of a third resin of a circuit element 250 including a conducting part covered by the third resin, thereby forming a first groove straddling the first resin and the third resin, a second groove straddling the second resin and the third resin, and a third groove extending between the first groove and the second groove; supplying a first conducting material in the first grove and the second groove thereby forming first wiring 210, including a plurality of independent parts; and supplying a second conducting material in the third groove thereby forming second wiring 220 electrically separated from the first wiring.

摘要： A method for manufacturing a light-emitting module includes a step of providing a bonded board including a board including, on a first surface, a circuit pattern and wiring pads that are continuous with the circuit pattern and each have bottomed holes and light-emitting segments connected on a second surface of the board with an adhesive sheet interposed therebetween and including an array of light-emitting devices; a step of supplying electrically conductive paste inside the bottomed holes and on portions of the surface of the wiring pad around the bottomed holes through openings of a mask; and a step of performing thermal compression to harden the electrically conductive paste such that the thickness of the electrically conductive paste on the portions of the surface of the wiring pad is smaller than the electrically conductive paste at the timing of being disposed through the openings of the mask.

摘要： A method for manufacturing a light-emitting device includes preparing an intermediate product; the product includes a light-emitting element provided with pairedelectrodes at a first surface and a first covering member covering the light-emitting element such that portions of surfaces of the paired electrodes are exposed. A a metal paste layer is formed, continuously covering the exposed portion of the paired electrodes and the first covering member. Paired wirings are formed, for preventing the paired electrodes from being short-circuited. The metal paste layer on the paired electrodes and the metal paste layer on the first covering member are irradiated with laser light to remove the metal paste layer between the paired electrodes and a portion of the metal paste layer on the first covering member.
