Abstract
Abstract A single in-line package adapted for surface mounting to a printed circuit board comprises an electronic component, a plurality of leads and a specially configured housing that encloses and protects the electronic component. The outer ends of the leads extend adjacent a tapered lower edge of the housing. The housing further has projections for engaging the upper surface of a printed circuit board to maintain the housing in a stable upright orientation with the outer ends of the leads in physical contact with corresponding solder pads on the printed circuit board during solder re-flow. The tapered edge of the housing is configured to permit subsequent inspection of a plurality of resulting solder joints for acceptable whetting.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
155 words
A single in-line package adapted for surface mounting to a printed circuit board, comprising: an electronic component having a plurality of electrical contacts; a plurality of parallel leads having inner ends and outer ends, the inner ends of the leads being electrically connected to corresponding ones of the electrical contacts of the electronic component; and a housing enclosing the electronic component so that the outer ends of the leads extend adjacent a tapered lower edge of the housing, the lower edge terminating before a pair of opposite ends of the housing and defining a pair of projections for engaging the upper surface of a printed circuit board to maintain the housing in a stable upright orientation with the outer ends of the leads in physical contact with corresponding solder pads on the printed circuit board during solder re-flow, whereby the tapered edge permits subsequent inspection of a plurality of resulting solder joints for acceptable wetting.
Claim 2
Dependent Claim
155 words
