Solder height
WebWave height is defined using the PWB as the reference. As shown in Fig. 3, the maximum wave height where the solder does not go up on the PWB when the PWB enters the solder … WebThe solder fillet (height) of a surface can be identified in the color map, and detailed data can be acquired by profile measurement of the desired cross-section. By switching the magnification, it is possible to measure the entire shape or detailed parts of small and delicate mounted components with high accuracy and by non-contact means.
