introduction： There are several brands of dry film currently in use，Different brands have slightly different parameters when applying film，The parameters of different batches of dry film are also slightly different，The specific parameters should be communicated with the manufacturer and adjusted according to the situation of their own equipment。 When the dry film is applied，First, peel the polyethylene protective film from the dry film，Then the dry film resist is pasted on the copper-covered foil plate under heating and pressurization。The resist layer in the dry film softens when heated，Increased liquidity，By means of the pressure of the hot press roller and the adhesive in the resist The action of the agent completes the coating。Laminating is usually done on a laminating machine，There are many types of film models，danradical

introduction：Universal joint bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The failure accounts for a large proportion of motor failures. The loss caused by bearing damage is quite serious，A running electric motor produces all kinds of sounds and vibrations，If you find a cracking sound、Sliding sound、Metallic sound，The temperature increases obviously，It is compared with the usual operation when there is a difference，
