Moisture Barrier Bag Desiccant Packets for Electronic Component Packaging
What is desiccant
Desiccant is a drying agent that is used to absorb moisture from the air inside moisture barrier bags. Desiccant absorbs moisture vapor (humidity) from the air left inside that barrier bag after it has been sealed. Any moisture that penetrates the bag will also be absorbed. Desiccant remains dry to the touch even when it is fully saturated with moisture vapor.
How is desiccant packed?
Desiccant is packaged in small sealed pouches made from a white plastic called “Tyvek”, or brown “Kraft” paper. Tyvek pouches are very clean and sulfur free. Kraft pouches are economical.
Why are electronics moisture sentive
Certain kinds of electronic devices called “Surface Mount Devices” or SMD’s are mounted on a circuit card by high temperature soldering. The body of the SMD is made from plastic that absorbs moisture from the air. When the case is heated during soldering, the moisture inside turns to steam and may break the device as the steam escapes. Keeping SMD’s dry before sold
What is the advantages of such desiccant?
1) dust free, anti static
2) will not come out moisture after absorbed
3) different sizes can suit
4) desiccant bags can be used together with moisture barrier bags or humidity indicator card
