Abstract

A "J" lead edge clip is used to position a ceramic substrate to a circuit board and hold each in correct position until soldering. This clip design combines the assembly advantage of an edge clip with the handling advantages of a "J" lead and is described below. The clip 1, as seen in a side view in Fig. 1, consists of a top loop 2 and a primary strip 3. A serrated cut-off 4 is provided for detachment after soldering the joint. The clip 1 is attached to ceramic substrate 5 and serves as a spacer to position the substrate 5 from the circuit board 6. The clip 1 is held in position by the clip's spring tension to substrate 5. The edge clip 1 is held in the proper vertical position by a selvage strip 7 (Fig. 2) which is attached to top of clip 1. Index holes 8 on selvage strip 7 serve as locators for a drive mechanism (not seen).

Edge-Connected "J" Lead for Ceramic Substrates

A "J" lead edge clip is used to position a ceramic substrate to a circuit board and hold each in correct position until soldering. This clip design combines the assembly advantage of an edge clip with the handling advantages of a "J" lead and is described below. The clip 1, as seen in a side view in Fig. 1, consists of a top loop 2 and a primary strip 3. A serrated cut-off 4 is provided for detachment after soldering the joint. The clip 1 is attached to ceramic substrate 5 and serves as a spacer to position the substrate 5 from the circuit board 6. The clip 1 is held in position by the clip's spring tension to substrate 5. The edge clip 1 is held in the proper vertical position by a selvage strip 7 (Fig. 2) which is attached to top of clip 1. Index holes 8 on selvage strip 7 serve as locators for a drive mechanism (not seen). When clip 1 is properly positioned on the location block, it is sheared to a desired length and placed on the substrate 5.
