Development of Standard Samples for Internal Control of Tin Lead Bismuth as Cast Spectra
Due to the widespread application of tin lead bismuth series electronic solders in industry,the rapid and accurate detection of solder composition mainly relies on direct reading spectrometers.To ensure the accurate inspection of spectrometers,it is necessary to rely on standard samples.In order to save the company's inspection costs,the was standard samples independently developed.Through process design,composition design,sample preparation,segregation inspection,uniformity inspection,metallographic structure analysis,calibration,stability testing,and other steps,we have developed internal control standard samples with good uniformity and stability,dense organization,and no pore defects,which can be used for the calibration of direct reading spectrometers.
