Recommended pad layout (mm)
JK-nSMD Series
Solder reflow conditions
● Recommended reflow methods: IR, vapor phase oven, hot air oven, N2 environment for lead-free.
● Devices are not designed to be wave soldered to the bottom side of the board.
● Recommended maximum paste thickness is 0.25mm (0.010inch).
● Devices can be cleaned using standard industry methods and solvents.
● Soldering temprature profile meets RoHs leadfree process.
Notes: If reflow temperatures exceed the recommended profile, devices may not meet the performance requirements
