Product Introduction

PM645B is a high-performance industrial automation communication module that uses high-speed CMOS devices, supports MODBUS protocol, and supports
hardware flow control. It is an ideal choice in the field of industrial automation.

China”s manufacturing industry has achieved world-renowned achievements. From being backward and beaten, to now taking off as a dragon,
Chinese manufacturers have put in tremendous efforts and efforts.
However, it is undeniable that many products in China are still highly dependent on imports, and there are still technical difficulties that are
difficult to overcome in the R&D and production of Chinese products in these fields. Among them are core products related to the lifeline of China”s
industry, as well as industrial parts and components that are closely related to our lives. The three technologies that China is stuck in are lithography
machines, operating systems, and chips, which are just the tip of the iceberg! This article will take stock of many products that China relies heavily on
imports: photolithography machines 0 1

The accuracy of the photolithography machine used to manufacture chips determines the upper limit of chip performance, as well as the issue of
power consumption. ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ China “s chip technology development is actually very early, but due to various reasons, China”s chip research and development
has been delayed. I also shared an article with you earlier, “The chip fraud incident that year caused China’s chip development has been stagnant for more than ten years . ”

There are two synchronously moving workpiece stages in the lithography machine, one for carrying negatives and one for carrying films. The two need to be
synchronized at all times, with an error of less than 2 nanometers. The two worktables moved from static to dynamic, with an acceleration similar to that of a
missile launch. When working, it is equivalent to two large airplanes moving in tandem from takeoff to landing. A knife is stretched out from one airplane to
engrave words on the rice grains of the other airplane. The engraving cannot be damaged. Chip 0 2 China”s chip technology, ZTE and Huawei are stuck is
a typical example. Although some chips are made in China, many chips still rely on imports. The mass production accuracy of the most advanced foreign
chips is 10 nanometers, while in my country it is only 28 nanometers, a gap of two generations. According to reports, in many fields such as computer systems,
general electronic systems, communication
equipment, memory equipment, and display and video systems, the share of domestic chips in my country is 0.
