'Super Thin Advanced Tin~TM Coating Technology for Reduced Insertion Forces'

摘要

Increasing pin counts for multiple termination in both automotive and electronic interconnects continue to drive the need for reduced insertion forces. Design engineers are looking for material systems that will provide acceptable electrical performance / solderability generally achieved by using thicker tin coatings and simultaneously reduce insertion forces generally achieved by thinner tin coatings. In this paper we will present data that evaluates commercially available tin coatings, both hot dipped and electro-tinned, and compares performance of these coatings with a new Super Thin Advanced Tin~TM Coating Technology. Analysis will be in terms of electrical performance, solderability shelf life, and insertion forces. Data generated on coupon samples to predict performance will be provided alogn with results of performance seen in actual connectors.
