screen printing process the size of pad is then found that floats the chip within the constraints of screen printing so that the pad design conforms to the criterion 34 30 above the minimum floating requirement 34 within screen printing constraints from equations 2 and 3 computing a and b from equations 4 and 5 the paste quantity which is applied in a typical screen printing process is determined by the following equation paste quantity applied pad area paste height solder v sub f applied 5 28e4 mils sup 3 the typical screen printing deposits only about half the solder required to 34 float 34 the component to obtain a convex joint and pedestal height the outward pad extension l 0 is shortened such that while leaving the other parameters the same equations 2 3 4 and 5 yield the amount of solder applied to the shortened pad during screen printing is paste quantity applied pad area paste height solder v sub f applied 2 4e4 mils sup 3 with the modification to the length of the pad screen printing deposits a solder volume just adequate to 34 float 34 the component but not raise the component to a sufficient height.
