Reference IPC-D-275, para 5.3.2.3, Table 5-10 When calculating annular ring requirements, table 5-10 lists "Greatest Board, X,Y Dimension". The table uses this to list a manufacturing allowance. The larger the dimensions, the larger the allowance. Is this the actual board dimensions, or is it the panel size that is being used? Thanks, Tom Hybiske General Atronics Corp.
