MCM is a high -class electronic product developed on the basis of hybrid integrated circuits (HIC). It collects many VLS II microcircuits on a multilayer interconnected substrate, and then puts them in one case. This is an advanced hybrid integrated component.

MCM has many advantages, such as increasing the density of the components, reducing the length of the intercombs, a decrease in signal delay, a decrease in dimensions and weights and increasing reliability.

In principle, MCM must comply with the following conditions:

There are several naked VLSI chips;

The multilayer substrate contains more than 4 layers for wiring;

The efficiency of packaging (chip/square area) exceeds 20%;

The number of input-output contacts in the body is large or depends on the features of application;

Since plastic materials and film materials cannot adapt to high temperatures, MCM mainly uses MCM-C technology in the field of oil and gas intelligence.

Advantages in the performance of the multi -chip module MCM

High speed - several bare chips are set along with high density, which reduces the distance between the chips and the length of the transmission tract, and also significantly reduces the delay in the signal, thereby increasing the operating frequency.

High density - MCM -C may contain up to 100 layers; The width of the line MCM-D/distance between them: 5/10 μm; MCM-D packaging efficiency is more than 70%.

High efficiency of heat dispersion - the use of new residual heat technology guarantees that high -performance LSI with high density does not reduce productivity and reliability due to poor heat dispersion.

Low cost - assembly density, efficiency and reliability of work can be increased several times, which allows you to achieve a relatively low cost of applied products.

The CHITENG company is the first enterprise in China to produce and developed a digital hybrid module of an integral scheme with a temperature of 200 ℃, and is also the first company in China to use the HTCC process (11 layers) to high -class equipment for exploration and drilling energy resources. At the same time, we developed the first linear power source in China, which withstands a temperature of up to 250 ℃ (reliable work for more than 600 hours).
