In the early days, when electronic component design and manufacturing were still developing, the “burn-in” solution was used to screen out defective electronic components and products. This process allowed early-failing products to be identified and eliminated, preventing defective items from reaching customers and causing complaints. Statistical data shows that the lifespan of a batch of electronic products typically forms a “bathtub curve.” This means that there are higher rates of defective components at the beginning and end of their usage, but after a period of use, the defect rate drops to a near-zero stable state, resembling the shape of a bathtub curve.
