Table 1 contains the calculated safety boundaries and mounting accuracy for the flip chip used in the experiment, as well as three different solder mask thicknesses. Table 1. Calculated safety boundary and mounting accuracy: Tin ball diameter 190 microns, solder mask layer opening 190 microns, solder mask layer opening 160 microns, solder mask layer thickness (micrometers), safety boundary (micrometers), mounting accuracy (micrometers), mounting accuracy (micrometers) 5306501042533815514429. For flip chip and solder mask layers with reference points defined by local solder mask layers, the conclusion is:. In terms of solder ball diameter, minimum solder mask opening, and solder mask layer

After installation, weld the board and conduct electrical testing on the components. The measurement results of the daisy chain are shown in Figure 2 with blue dotted lines. The theoretical tolerance position for resistance welding is also shown in the figure. The three theoretical areas are: a consistently good and safe area, corresponding to the copper foil solder pad or welding area. a transition area, which is the tolerance area for solder resistance; But when mounted here, the welding will depend on the position of the solder mask An area that always goes wrong, which exceeds the tolerance limit of resistance welding; The connection in this area is not welded. The measurement of several boards shows that the position (tolerance) of the resistance welding is not always consistent, which may
