SMT toplotno profiliranje

Potrebno je profiliranje za refleksijo 4- Optimizacija faze: predgrejte (1-3} stopinja /s), namočite (60-120 s pri 150-180 stopinja<6°C/s). KIC thermal profilers use predictive algorithms for complex boards. Thermocouples attach to thermal mass areas for accuracy. Nitrogen environments permit 10°C lower peak temperatures. Ramp-to-spike profiles reduce tombstoning. DOE methods correlate profile settings with shear strength. Standards: IPC-7531 guidelines for profile validation.
