¿Por qué hornea el PCB que se ha producido a largo plazo?

Question

Accepted Answer

The purpose of baking is to remove the moisture from the PCB.
No matter the PCB is at production site or still in vacuumed package, both would increase the risk that PCB can absorb moisture.
If PCB is stored at a bad storage condition or over storage period, these would also make the PCB absorb moisture easily.
The high temperature would cause inner board moisture evaporation when assembly the damp PCB.
The PCB will have blister or delamination due to steaming.
