| Data on moisture absorption and dehumidification of an IC package
|
| Example of low-humidity storage of laminated PCB
|
Multi-layered PCBs absorb moisture at a faster rate as they become thinner. Layer break off and blistering will occur during reflow if the moisture content of the PCB exceeds 0.2% (weight.) Store laminated PCBs in an ultra-low humidity dry box. |
