Semiconductor manufacturing plants are growing driven by high demand

wallpapers Industry 2020-02-28

• Industry information

On an application basis. The market is segmented into semiconductor manufacturing/casting, semiconductor electronics manufacturing, and internal testing. The semiconductor manufactory/foundry division has a significant market share in semiconductor manufacturing equipment. The growth can be attributed to the high demand for semiconductors in consumer electronics, automobiles, medical devices, and machines. The semiconductor electronics manufacturing and testing home division is expected to grow at a considerable rate in the coming years. It is due to the increasing awareness of the testing of semiconductors and their components, as well as the strict specifications and standards for packaging various products.

 


 

•Bearing knowledge

Bearing installation is correct, affects the accuracy, life, performance. Therefore, the design and assembly department for the bearing installation to thoroughly study. You want to install according to operating standards. Items of operating standards are as follows:

(1) Clean the bearing and bearing related parts

(2) Check the dimensions and finishing of relevant parts

(3) Installation

(4) Check after installing the bearing

(5) Provide lubricant before installation, open the package.

 

General grease lubrication, do not clean, directly fill the grease. However, the instrument or high-speed bearings, you need clean with fresh oil, remove the rusting agent coated on the bearings. The bearing that removed antirust agent, natural rust, so cannot place ignore.Bearings sealed with grease shall be used directly without clean. Bearing mounting method, bearing structure, fit, conditions, and different, generally, because of the shaft rotation, so the inner ring needs interference fit: cylindrical bore bearing, multi-purposes press, or multi-purposes hot mounting method. For taper holes, install directly on the tapered shaft, or connect with a sleeve. When mounting to the shell, there is usually more clearance fit and interference in the outer ring, which is often pressed in with a press machine, or there is also a cold shrink-fit method for installation after cooling. With dry ice as coolant, severe shrinkage with the fitting of the occasion, the moisture in the air will condense on the surface of the bearing. So, need proper antirust measure.
