PPTC SMD can be cleaned by standard methods. · Requests that customers comply with our recommended solder pad layouts and recommended reflow profile. Improper board layouts or reflow profile could negatively impact solderability performance of our devices. SMD2018 Series Alpha-Top (Sea & Land Alliance) Recommended Solder Reflow Conditions 300 Preheating Cooling Soldering ‧Recommended reflow methods：IR, vapor phase oven, hot air oven. ‧Devices are not designed to be wave soldered to the bottom side 250 of the board. 200 ‧Recommended maximum paste thickness is 0.25 mm (0.010 inch). 190 ‧Devices can be cleaned using standard method and solvents. 160 Note：If reflow temperatures exceed the recommended profile, 100 0 devices may not meet the performance requirements. 60-120 sec. 30~60sec.
