Abstract
A method of assessing discrepancy between a target value and a measured value of a parameter of contact area produced between flow of solder ejected from a nozzle and a surface is defined in the present application. This method comprises the steps of: providing a surface of material through which contact area between solder ejected from a nozzle and a side of the surface can be visually detected, for example using a camera; flowing solder through a nozzle and then bringing the solder into contact with a side of the surface, thereby creating contact area between the solder and said side of the surface; detecting the contact area from the other side of the surface so that a value of a parameter of said contact area can then be measured; and assessing any discrepancy between the target value and the measured value so that any necessary compensation in order to achieve the target value can be programmed.
