Embodiment Construction
[0021] The present invention will be further described below with reference to the drawings and embodiments.
[0022] Such as Figure 1 ~ Figure 3 As shown, the present invention includes the following steps:
[0023] a. The ceramic substrate 1 covers the die attach area by electroplating high-reflectivity metallic silver or aluminum, which effectively increases the reflectivity of light; and is printed into a circuit.
[0024] b. Connect the heat sink 2 of high thermal conductivity copper alloy at the bottom of the ceramic substrate 1 by injecting silver into the holes.
[0025] c. Use high thermal conductivity silver glue with a thermal conductivity of 15w / m.k or more to fix the chip 3 with a length and width of 30mil (1mil=1 / 1000 inch=0.254mm) or more, and use gold wire 4 to solder and connect the circuit.
[0026] d. A porous metal template 5 is placed on the ceramic substrate 1, and each channel 51 contains a wire-bonded wafer 3, such as figure 1 Shown.
[0027] e. The phosphor and...
