Webchamber and initial reflow cannot be met then the parts must be rebaked and resoaked according to 3.1.4 and 3.1.5. The minimum time between reflows shall be 5 minutes. Table 2 — Reflow profiles Sn-Pb eutectic assembly Pb-Free assembly Reflow condition Pkg. thickness ≥ 2.5 mm or Pkg. volume ≥ 350 mm3 3 Pkg. thickness < 2.5 mm and Pkg ... WebThe assembly is reflowed above the liquidus point of the solder (183°C for Sn63, 179°C for Sn62) for a target time of 60 seconds ± 15 seconds. It should be noted that this time above liquidus is measured not only during the profile’s rise, but also during its cool-down. The cool down rate of the profile should be controlled within 4°C per ...
