How to choose a proper memory card?

Source: local   Editor: Alex   Update Time :2019-05-07
Memory cards can be divided into CF cards, MMC cards, SD cards, memory sticks and so on. At present, there are several mainstream memory card identifications such as Class and UHS. UHS product is better than Class products but its price is also higher than the latter. In addition, many factors will contribute to various performances even in similar product serious. It is recommended that friends w...

This article mainly tells us about basic components of photoresist, including polymer, solvent, photosensitive agent and additive. Photoresist can be divided into two types: positive photoresist and negative photoresist. Both of them have different features and application, and when choosing proper photoresist, you need to consider the resolution, aspect ratio, exposure speed and so on.

What is the value of an ASML lithography machine at price of $100 million? (3)

ASML, the leader in the field of lithography machine, monopolizes the high-end lithography machine market. As the technical threshold of the lithography machine is extremely high, few companies have the ability to produce high-end lithography machines. Therefore, it’s no wonder one EUV lithography machine is about $100 million, equivalent to F35, the fourth generation fighter of American Empire.
