Solución
①Select the 80-110℃ range according to the supplier data sheet; ②dehumidifying dryer preferred; ③3-4 hours guaranteed; ④moisture content <0.02% verification; ⑤dew point monitoring.
Conclusión clave
Supplier differences in PCABS drying must be confirmed; dehumidifying dryers are standard equipment; moisture content verification is the final criterion.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
