- chip LEDs By integrating chip LEDs with high density, it can be used as a surface light source, and such a surface light source is suitably used for a backlight for a liquid crystal display that is particularly required to be thin.
- it is used as a surface-emitting illumination device for guidance display illumination lamps, evacuation exit lamps, advertising lights, and the like.
- Thickness accuracy of the chip LED mounting substrate is extremely important when the elements mounted on the substrate are sealed with a transfer molding.
- transfer molding refers to a technique in which a resin is press-fitted into a clamped mold.
- the thickness of the substrate used for chip LEDs is generally from 0.06 mm to 1. Omm. If the accuracy of the plate thickness is poor, there will be a gap between the substrate and the mold during clamping during transfer molding. As a result, press-fitted grease leaks from the gap, resulting in molding defects.
- the required accuracy of the substrate thickness in such transfer molding is, for example, a tolerance of + —0.05 mm or less (range is 0.1 mm) for a substrate with a thickness of 1.
- Omm preferably a tolerance of + —0. .03mm or less (range is 0.06mm). Obedience On the other hand, if there is a substrate with high thickness accuracy, the defect rate can be greatly reduced in the chip LED manufacturing process, which is extremely significant in the industry.
- Alicyclic epoxy resin EHPE-3150 (manufactured by Daicel Chemical Industries, Ltd.) 50 parts by weight, bisphenol A type epoxy resin: AER-6051EK75 (manufactured by Asahi Kasei Kogyo Co., Ltd.), 40 parts by weight, and glycidyl methacrylate copolymer : Marproof G-0150M (manufactured by NOF Corporation) 10 parts by weight was dissolved in 50 parts by weight of methyl ethyl ketone (hereinafter referred to as MEK). (Varnish A)
- the white epoxy varnish was impregnated with 0.1 mm thick glass cloth WEA-116E (manufactured by Nittobo Co., Ltd.) and pre-dried at 150 ° C. for 5 minutes to obtain a pre-preda having a 50% rosin composition content.
- WEA-116E manufactured by Nittobo Co., Ltd.
- a stack of 18 mm thick copper foil is stacked on the top and bottom of one, four and ten layers of this pre-preda, and is heated and pressed at a pressure of 40 kgfZcm 2 and a temperature of 170 ° C. 0.4 mm thick and l mm thick metal foil-clad white laminates were obtained.
- a white laminate was obtained in the same manner as in Example 1 except that the composition of the white epoxy varnish was changed as follows.
- Bisphenol A-type epoxy resin AER— 6051EK75 (Asahi Kasei Kogyo Co., Ltd.) 50 parts by weight
- Cresol novolak type epoxy resin YDCN-704 (Toto Kasei Co., Ltd.) 50 A part by weight was dissolved in 40 parts by weight of MEK.
- Varnish C and Varnish D are mixed, and anatase-type titanium dioxide TA-500 (Fuji Titanium Industry Co., Ltd.) 73 parts by weight as a white pigment, HR-101 (Chuo Synthetic Chemical Co., Ltd.) as a fluorescent brightening agent 0.3 parts by weight were added to obtain a white epoxy varnish.
- a pre-preda was prepared in the same manner as in Example 1, and the layers were laminated, and copper foils were stacked on top and bottom, and heat-pressed to form 0.1 mm thickness, 0.4 mm thickness, 1 mm thick metal foil-clad white laminates were obtained.
- Example 1 After removing the copper foil of the 0.1 mm metal foil-clad white laminate obtained in Comparative Example 1 by etching, the visible light reflectance of the substrate surface was measured according to JIS-Z8722, Further, the visible light reflectance after heat treatment at 180 ° C. for 4 hours was measured in the same manner. The results are shown in Fig. 1. As is clear from FIG. 1, it can be seen that the substrate of Example 1 has improved heat resistance with less deterioration in the short wavelength region than the substrate of Comparative Example 1.
- a high pressure mercury lamp ultraviolet light emission spectrum: 253.7 nm, 365 ⁇ m
- Example 1 has improved UV resistance with less deterioration in the short wavelength region than the substrate of Comparative Example 1.
- the glass transition temperature was determined according to ⁇ O IS-C6481. That is, the copper foil of the 0.4 mm-thick metal foil-clad white laminate obtained in Example 1 and Comparative Example 1 was removed by etching. After that, cut it out to a size of 7mm x 70mm, measure it with a free-damping type dynamic viscoelasticity measuring device (Less Power Company, model number: AD-1100AD) at a heating rate of 2 ° CZ, Loss tangent peak temperature force The glass transition temperature was determined.
- a free-damping type dynamic viscoelasticity measuring device Less Power Company, model number: AD-1100AD
- Example 1 The glass transition temperature of the white laminated sheet of Comparative Example 1 (after removing the metal foil) was 200 ° C and 190 ° C, respectively. As a result, both of the white laminates of Example 1 and Comparative Example 1 had practically sufficient heat resistance, but among them, the white laminate of Example 1 was superior in heat resistance. I understand that.
- Example 1 The thickness of the lmm-thick metal foil-clad white laminate (1000mm x 100 Omm) obtained in Comparative Example 1 was measured using a lZlOOOmm micrometer at a total of 60 points at intervals of 250 mm in length and 7 Omm in width. The thickness range and the difference between the maximum and minimum values were determined.
- Example Table 1 shows the thickness data of the metal foil-clad white laminate of Comparative Example 1. The difference between the maximum thickness value and the minimum thickness value in Example 1 and Comparative Example 1 was 0.055 mm and 0.115 mm, respectively.o
- the metal foil-clad white laminate of Example 1 has an improved plate thickness accuracy compared to Comparative Example 1 and sufficiently satisfies the required accuracy.
- the whiteness for printed wiring boards is excellent in the heat resistance and the thickness accuracy with high reflectivity in the visible light region and significantly less discoloration due to heating and ultraviolet rays.
