Problems solved by technology

For example attached figure 1 A plurality of LED chips 2 are mounted on an insulating substrate 1, and the LED chips 2 are flip-chip mounted on a circuit pattern (not shown) on the insulating substrate 1 via solder balls 3, and finally sealed via an encapsulating resin 4. The surface of this package The light source needs to form a circuit pattern on the insulating substrate 1 in advance. After the circuit pattern is encapsulated, the series and parallel connection cannot be adjusted and changed. In addition, after a certain LED chip fails, it is difficult to find the failed LED chip.

Abstract

The invention provides a lighting device manufacturing method. A circuit pattern on the lower surface of an insulation substrate is led out through notches, grooves and through holes. The circuit pattern can realize flexible wiring, and helps search of a failed LED chip, and detection of the plurality of through holes can be realized; conductive nails can prevent overflow of conductive paste, andreduce use of the conductive paste, and conductivity is better; and through a lift plate, electrical connection between the conductive paste and electrode welding plates is realized easily and reliably.

Description

technical field [0001] The invention relates to the field of LED package manufacturing, in particular to a method for manufacturing an illuminating device. Background technique [0002] Most of the existing LED packages are in the form of COB, which utilizes circuit patterns on an insulating substrate to realize series-parallel connection of LEDs. For example attached figure 1 A plurality of LED chips 2 are mounted on an insulating substrate 1, and the LED chips 2 are flip-chip mounted on a circuit pattern (not shown) on the insulating substrate 1 via solder balls 3, and finally sealed via an encapsulating resin 4. The surface of this package The light source needs to form a circuit pattern on the insulating substrate 1 in advance. After the circuit pattern is encapsulated, the series and parallel connection cannot be adjusted and changed. In addition, after a certain LED chip fails, it is difficult to find the failed LED chip. Contents of the invention [0003] Based on...
