Abstract
A post locating section (200) of a header (10) includes an array of post-receiving apertures (222,224,242) extending to a mounting face (30). Post sections (110,110',148) of header contacts (100,130,140,160) extend through the apertures of the post locating section (200) and beyond the mounting face for insertion into through-holes of a circuit board (40) upon mounting the header (10) thereto. The apertures (222,224,242) are referenced to a structure (270) of the post locating section defining a datum and are optimally dimensioned. The method of dimensioning the apertures includes assessing the manufacturing tolerance limits of the drilled circuit board through-hole diameters and locations, and of the dimension of the post sections, and determining the maximum permissible displacement of the post sections which will still permit entry of the tip sections (112,112',150) into the through-holes (36,38), and bounding the limits of the permissible displacement with the aperture side walls in a manner permitting float of displaced post sections during insertion through the through-holes.
