Ceramic Substrate:

The AlN ceramic substrate is a new generation of high performance ceramic substrate with high thermal conductivity (theoretical value is 319W/mK, commercial AlN substrate thermal conductivity is greater than 140W/mk), and low dielectric constant ( 8.8) and dielectric loss (~4 × 104), and the ratio of thermal expansion coefficient (4.4 × 10 -4 / ° C) with silicon, but because of the high cost, has not been able to apply on a large scale; Al2O3 ceramic substrate Although the thermal conductivity is not high (20W/mK), it is the most widely used ceramic substrate because of its relatively simple production process, low cost and low price. The high-precision electronic ceramic casting machine first mixes the pulverized powder with a binder, a plasticizer, a dispersing agent and a solvent to prepare a slurry having a certain viscosity. The slurry flows down from the hopper and is scraped by a scraper at a certain thickness. The pressure is applied on a special base tape, dried and solidified, and then peeled off from the top to form a film of the green belt, and then the raw material strip is subjected to die-cutting, laminating, etc. according to the size and shape of the finished product, and is formed into a sintering process. The finished blank has the main advantages of high temperature resistance, high electrical insulation performance, low dielectric constant and dielectric loss, high thermal conductivity, good chemical stability, and similar thermal expansion coefficient of components. The equipment required for the process includes a vacuum defoaming machine, a casting machine, a printing machine, an isostatic press, a sintering furnace and the like.

Application:

The role of ceramic substrate ceramic substrate according to the field of ceramic substrate application, is divided into HIC (hybrid integrated circuit) ceramic substrate, focusing potentiometer ceramic substrate, laser heating fixing ceramic substrate, chip resistor substrate, Network resistor substrate, etc.; according to different processing methods, ceramic substrates are divided into two types: molded tablets and laser scribe films. The ceramic substrate in the chip resistor substrate is a part of the chip resistor. The upper layer of the substrate is coated with different semiconductor materials, and then copper is plated on both ends for soldering. The biggest advantage of the whole resistor is that the volume can be made very well. small.
