Case Analysis of Welding Quality of Robot Variable Frequency Board
The welding quality of the inverter board directly affects the function of inverter board.In this paper,the weld-ing quality of an actual robot inverter board is analyzed and evaluated by means of visual inspection,X-ray inspection,solder joint tensile test,sectional metallographic observation,scanning electron microscopy (IMC),and morphology char-acterization.Corresponding suggestions are also put forward according to the evaluation results.
