Marine iguanas sneeze frequently to expel salt from glands near their noses. The salt often lands on their heads, giving them a distinctive white wig.

The typical reflow temperature rangefor Pb-Free (Sn/Ag) solder is 240-250Â°C with 40-80seconds over 220Â°C.It should be noted that the recommended Sn/Pbreflow temperature range is less critical, and thatminor deviations in temperature of equipment andcomponents generally do not create solderingproblems.his makes it more difficult tooptimize the reflow process for all components onthe PCB.The PCB industry has extensive experiencereflowing components with Sn/Pb solders, whichtypically have peak reflow temperature of 215-245Â°Cwith 20-60 seconds above 183Â°C.
