Ceramic PCB in the end where expensive?

As the saying goes, the only advantage of cheap things is cheap, and the only disadvantage of expensive things is expensive. The PCB industry is the same. 1oz vs 2oz Resin printed circuit board, metal printed circuit board, ceramic printed circuit board, which resin is the cheapest, ceramic is the most expensive, so where is ceramic expensive?

PCB and we need everyone to buy clothes and shoes are also different, it is a belong to their own inner, invisible things. Usually buy luxury goods, are students can see and touch, can learn to harvest countless envy of the sun, but Chinese ceramic PCB you use or not, how to test a circuit board with a multimeter in the eyes of consumers, the basic problem does not make any difference, the soft quality of electrical appliances is invisible. So why do they still have a lot of big manufacturers to follow it?

At present, the application of China's ceramic circuit board is basically a first-class factory. Small and medium-sized enterprises need quality assurance, and small and medium-sized enterprises need more output and cost control, so at present ceramic PCB has not been widely used in China.

The price of ceramic PCB can be analyzed from the following aspects:

Substrate material: Ceramic substrate is the main aluminum nitride alumina two, the cost of these two materials than resin substrate or aluminum substrate, copper substrate is much more expensive. Starting with the base material, the price is already spread out.

Process technology: In terms of manufacturing technology, whether it is LTCC, HTCC, DPC, DBC or LAM technology, its manufacturing technology will be more demanding, and the co-firing temperature required by LTCC and HTCC is difficult to control.

product performance: As the saying goes, "a penny of the goods", this sentence in the ceramic PCB body we show incisiveness, PCB has many important demand points, such as through the thermal conductivity, thermal expansion influence coefficient, dielectric constant, stability, high frequency part loss. In terms of these issues, ceramic PCBS can really do their current top. Its thermal conductivity is one of the best among the current PCB, thermal expansion change coefficient and silicon chip can be more effective match, dielectric constant is very low, conductive material performance and excellent, corrosion resistance, high temperature resistance, high frequency information loss......

Saying so much, it can be seen that ceramic PCB is not expensive for no reason. Although consumers can not see, even if the basic do not understand, but the quality can still be felt. Long service life, good stability, can reflect the quality of the product, that is, quality, will attract today's consumers. A price war by itself will not attract millions of consumers.

Looking at the world, ceramic PCB has been used for nearly half a century, and domestic ceramic PCB has just emerged. Due to technical reasons, a large number of ceramic PCBS still rely on imports to maintain domestic production. The research and development of ceramic PCB by domestic new technology enterprises has never stopped. For example, some enterprises that strive to let China catch up with the world, and keep moving forward with the country. In the future, more technologies will be added to make it more efficient and more accurate to control costs. By then, Chinese ceramic PCB will be famous in the world.
