1. IPC-2221 8.3.1.7 RADIAL- COMPONENTS Angularity is required for clearance in the next higher assembly; or That edge of the body nearest the surface of the board parallels the board surface within 10 degrees and is no less than 1.0 mm and no more than 2.3 mm from the surface. Components of configurations F through J of Figure 8-22 are not included under the angularity exception. Figure 8-23 Radial two lead component mounting, mm

2. IPC-2221 8.3.1.7 RADIAL- COMPONENTS Radial-leaded components with coating meniscus on one or more leads should be mounted such that there is visible clearance between the meniscus and the solder fillet. Trimming of the meniscus is prohibited. Figure 8-24 Meniscus clearance, mm

3. IPC-2221 8.3.1.7 RADIAL- COMPONENTS Radial-Leaded Components (3 or more Leads) - Radial-leaded components with three or more leads vary in lead spacing. The design lead spacing is generally a function of the spacing at which the leads exit from the body of the component (see Figure 8-25) and the nearest pattern of grid intersections that provides for suitable conductor routing. Figure 8-25 "TO" can radial-leaded component, mm
