Abstract

The invention discloses a manufacture method for a mirror surface blind trough aluminum substrate. The manufacture method for the mirror surface blind trough aluminum substrate comprises the following steps: firstly, producing a circuit line on a core plate and conducting pretreatment; then, selecting a mirror surface aluminum substrate with corresponding thickness according to the need of a user, pretreating the mirror surface aluminum substrate, and pasting stagnant glue on the side which is not the mirror surface and conducting roasting treatment; finally, compressing the mirror surface aluminum substrate together with the stagnant glue in an overlapped mode, so that a mirror surface blind trough aluminum substrate is formed. A normal drill and an end mill can be used when the manufacture method for the mirror surface blind trough aluminum substrate is adopted, thus cost of consumable items is reduced. Meanwhile, the manufacture of the mirror surface aluminum substrate is not affected by the thickness of a plate, production efficiency and quality are improved and market popularization prospect is good.

Description

technical field [0001] The invention relates to the technical field of manufacturing printed circuit boards, in particular to a method for manufacturing a mirror-surface blind groove aluminum substrate. Background technique [0002] Mirror aluminum substrate is very suitable for COB packaging, which has the following advantages: [0003] 1. Good heat dissipation: mirror aluminum substrate (also known as mirror silver aluminum substrate) adopts thermoelectric separation technology, and the thermal conductivity of ordinary aluminum substrate with insulating layer is 1W, 1.5W and 2W. The thermal conductivity of the mirror aluminum is 137W, which greatly improves the heat dissipation of the chip; [0004] 2. High light efficiency: the reflectivity of our ordinary immersion gold aluminum substrate is 80%, the reflectivity of cup-hole aluminum substrate is 85%, the reflectivity of silver-plated aluminum substrate is 95%, and the reflectivity of mirror silver aluminum substrate is...
