specific Embodiment approach 1

[0046] Specific Embodiment 1: In this embodiment, the method for preparing MAS-based glass-ceramic electronic substrates by water-based tape casting is carried out according to the following steps:

[0047] 1. Preparation of MAS glass powder by melting method:

[0048] MgO, Al 2 o 3 and SiO 2 According to the molar ratio of (2-2.5): (1-2): (5-6) to mix the mixture, and then add B to the obtained mixture 2 o 3 and P 2 o 5 Obtain powder; among them, B 2 o 3 The mass of the powder accounts for 2% to 5% of the total mass of the powder, P 2 o 5 The mass of the powder accounts for 2% to 5% of the total mass of the powder; the obtained powder is mixed in ethanol with a mass percentage of 95% for 22 to 26 hours, and then dried at 50°C to 80°C for 10 to 12 hours. After crushing, pass through a 60-mesh sieve, keep the sieved material at 1500°C-1550°C for 4-6 hours, then quench to obtain glass slag, and use planetary ball milling for the obtained glass slag at a ball milling sp...

specific Embodiment approach 2

[0062] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the ball-to-material ratio of the planetary ball mill described in Step 1 is (10-15):1. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0063] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in step 1, the obtained glass slag is crushed and passed through a 100-mesh sieve by a planetary ball mill. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a method for preparing an MAS (MgO-Al2O3-SiO2) series microcrystal glass electronic substrate in a water-based tape-casting mode, and relates to a method for preparing the MAS series microcrystal glass electronic substrate, and the method can be used for solving the problems that the use of organic solvents can do harm to human bodies and the environment, the production process has potential safety hazard, the production cost is relatively high and reception of signals is slow in the data transmission process in a conventional method for preparing the MAS series microcrystal glass electronic substrate. The method comprises the following steps: I, preparing MAS series glass powder, II, preparing MAS water-based slurry, III, preparing a crude glass strip, IV, preparing a crude substrate material blank, and V, sintering. By adopting the method, harm to the human bodies and the environment is alleviated, the potential safety hazard in the production process is reduced, the cost is low, and the problem that the reception of the signals is slow in the data transmission process is solved. The method is applied to preparation of the MAS series microcrystal glass electronic substrate.

Description

technical field [0001] The invention relates to a method for preparing an MAS-based glass-ceramic electronic substrate, in particular to a method for preparing an MAS-based glass electronic substrate by a water-based tape casting method, and belongs to the technical field of low-temperature co-fired ceramic substrate preparation. Background technique [0002] With the rapid development of information and communication technology, electronic components are developing in the direction of high integration, miniaturization, and surface packaging. In order to adapt to the development of electronic components, integrated components and high-density packaging ceramic substrates have become an inevitable trend. MgO-Al 2 o 3 -SiO 2 (MAS) series glass-ceramics does not contain alkali metal oxides, and the properties of MgO in the glass are between the network outer body oxide and the intermediate oxide, which not only has the effect of breaking the network, but also has a certain a...
