  • Low-insertion force solder-bearing lead
    Patent number: 4482197
    Abstract: A low-insertion force solder-bearing lead (10) includes a resilient clamping finger (20) having an inner planar surface (48) for engaging a planar surface (50) of a substrate circuit device (16) in parallel mating relationship. Respective portions (26 and 28) of a resilient contact finger (22) and a solder preform (12) define a noncircular camming surface (58) which extends relative to the inner planar surface (48) of the clamping finger (20) at an angle of not more than 45.degree. to facilitate flexing of the contact finger in the assembling of the lead (10) to the substrate circuit device (16). Portions (68) of the solder preform (12) smear across a contact pad (14) during the lead assembling operation to facilitate wetting of the preform to the contact pad in a subsequent soldering operation.
