The terminals o<\/span>f the connector are matte tin and bright tin, do you know the difference between them?<\/p>\n

In order to comply with the RoHS and REACH specifications (restrictions on the Pb content of tin-plated products), the component manufacturing has introduced a new method to replace the original tin-lead surface treatment of electronic parts lead, so as to meet the new environmental protection soldering process requirements. Among them “Full tin plating” is further divided into two types: “Matte tin” and “Bright tin”. How to choose the type of tin plating to avoid quality issues during the soldering process, such as terminal yellowing, Tin layer avalanche, poor soldering (Deweting), false soldering…etc. It is obviously subjects that should be understood and paid attention to.<\/p>\n

In fact, the bright surface and the matte surface are the reflection and refraction of light on the object. The smoother the surface of the object, the more comprehensive the reflected light, so it will look brighter, otherwise it will become darker. So why is there a difference between bright tin and matte tin? The answer is additives. The surface roughness of tin is basically not much different, and the residue of additives can smooth the uneven surface, so that light can be reflected more comprehensively..<\/p>\n
