introduction：When the solder paste is placed in a heated environment，Solder paste reflux is divided into five stages， First of all，The solvent used to achieve the desired viscosity and screen performance begins to evaporate，The temperature must rise slowly(About per second3°C)，To limit boiling and splashing，Prevent the formation of small tin beads，In addition，Some components are more sensitive to internal stress，If the external temperature of the component rises too fast，Will cause fracture。 Flux is active，Chemical cleaning operation commenced，The same cleaning action occurs for both water-soluble and no-wash types of flux，Its just a slightly different temperature。Remove metal oxides and certain contaminants from the metal and solder that will be combined

introduction：KOYOBearings commonly used lubricants are lubricating oil and grease two kinds。When the circular velocity of the shaft is less than4-5m/swhen，Or parts of the car that cannot be lubricated with lubricating oil，All are lubricated with grease。The advantage of grease lubrication is that the sealing structure is simple，Grease is not easy to drain，It is not affected by temperature，Add a grease can be used for a long time。 There are two problems with grease，One is to follow the requirements of the cars manual，Choose the right grade of grease。Such as，Automobile water pump bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is fixed in the mechanical transmission process
