Soldering Recommendations, Precautions when using SMT, and SMT FAQ

B6A-SMT ORIENTATIONS

Figure 1: Most Sturdy: Vertical bolt and horizontal ring lug mount.

Figure 2: Less Sturdy: Horizontal bolt and horizontal ring lug mount. Best for factory wiring only.

In Figure 2, when using a headed screw or ring lug and bolt it's recommended that the head of the screw hangs off the edge of the board. Screws with little or no clearance between the head of the screw and the board can result in mechanical and electrical fouling.
