  • SMD soldering apparatus
    Patent number: 5769304
    Abstract: In the attachment of surface mounted devices, melting of solder is monitored so that immediately thereafter heating may be stopped. The solder paste, which is stump-grey below the melting point, will radically change its reflectance upon melting, this being detectable by means of a video camera.
