Solder Reflow • Recommended reflow method: IR, hot air, nitrogen. • Recommended maximum paste thickness: 0.25mm (0.010in) • Devices can be cleaned using standard methods and aqueous solvents. • Experience has shown the optimum conditions for forming acceptable solder fillets occur when a reasonable amount of solder paste is placed underneath each device’s termination. As such, we request that customers comply with our recommended solder pad layouts. • Customer should validate that the solder paste amount and reflow recommendations meet its application. • We request that customer board layouts refrain from placing raised features (e.g. vias, nomenclature, traces, etc.) underneath PolySwitch devices. It is possible that raised features could negatively impact solderability performance of our devices. Rework • Standard industry practices. (Please also avoid direct contact to the device.)
