Dimensions of reels according to EIA RS481 or IEC 2863. External diameter 330 mm ± 2 mm. Soldering: Depending on the application of the KSC, this component is suited to the following methods: Flow soldering – The KSC terminals being SnPb plated over a Nickel barrier, the use of slightly activated flux is suitable. – Soldering on double wave machine. The bath temperature is generally 255°C ± 5°C and soldering time Ͻ 5 sec. – Cleaning according to usual washing processes. Vapor phase reflow soldering Temperature: 215°C; Duration: up to 60 seconds Infrared reflow soldering Temperature: 200°C, with peak of 230°C during 10 to 15 seconds Conductive inks Silver based inks can be used for the connection of KSC on PC board. Curing conditions depend on the type of conductive ink. DataSheet4U.com DataShee 2 = 1.6N .
