apparatus 22 shown in fig1 by a bolt or mounting rod indicated at reference number 38 the clamping portion 36 typically includes a ledge or cut out area 40 for receiving a squeegee blade 42 as shown in fig3 a and 3b a perforated metal strip 44 shown in the left most portion of fig3 b or individual washers 45 receive threaded bolts 46 which are received by threaded apertures 48 in the clamping portion 36 as shown in fig3 a fig4 shows a prior art squeegee blade 42 including a series of mounting apertures 50 a through 50 h that allows for the bolts 46 which pass through the perforated strip 44 and for washer 45 to also pass through the apertures 50 a through 50 h into the threaded aperture 48 of metal clamping portion 36 of the apparatus thus referring to fig3 a it can be seen that if the combination clamping structure 36 and squeegee blade 42 are moved in the direction as indicated by arrow 52 the edge 54 of squeegee blade 42 which is in the front or forward position will bear against the screen mask as it moves across the one or more circuit boards and evenly distributes the solder paste referring to fig4 it is seen that there are two possible useable edges 54 and 56 for distributing the solder paste for example if edge 54 becomes damaged or worn edge 56 may be used as the contact or front edge by.
