What is Climatest Symor® dry cabinets for PCB, auto dry cabinets?
Climatest Symor® dry cabinets for PCB, also called auto dry cabinets, are air-tight automatic dehumidifying dry boxes that protect moisture sensitive items from humidity-related damages, it maintains a <5%RH low humidity internal environment, that can effectively eliminate the risks of failures result from improper storage during assembly process.
Application of dry cabinets for PCB
Dry cabinets for electronic components are indispensable in electronic manufacturing industry, it is the optimal storage solution for IC packages, PCB boards, LED, SMD, SMT, and also tape and reels, printed wiring boards(PWB), polymide film, feeders, other ideal application for capacitor ceramic parts, connectors, switches, welding bar, the auto dry cabinets conform to IPC/JEDEC J-STD 033 standard.
How do dry cabinets for PCB influence the SMT production?
MSL components, like IC, BGA,PCB, are very sensitive to humidity, these components have certain requirements for the storage environment, unlike the civilian moisture-proof dry boxes, the dry cabinets for PCB should reach a very low humidity point, the dehumidifying and recovering speed should also be very fast, moreover, the whole cabinets should be ESD safe, the dry cabinets used in the cleanroom must be stainless steel material to meet strict hygiene requirements.
During reflow heating process, trace moisture vapor penetrate into the IC packages, the absorbed moisture expand quickly inside, this result in invisible damages, like wiring failure, popcorn and micro-cracking, even cracking to surface, these defects are not easy to be seen in the early stage, however, these invisible, potential problems enter into the market, then faculty products return and complains follow.

|
Moisture in the ambient penetrates into the packages. |
During heating, the water steam pressure increases, that separates the die and resin. |
The water steam continues to expand under heating, blowing up the packages. |
The water steam breaks the packages, which causes micro-cracking. |
IPC/JEDEC J-STD-033 standard specifies“Standard for Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices.”, it require low humidity storage for moisture sensitive components.
<5%RH Series dehumidifying speed:
Open door 30 seconds and then closed, the humidity will recover to <5%RH within 30 minutes,see below curve: (Ambient 25 degree C, humidity 60%RH)
WHAT ARE THE COMMON METHODS TO STORE ELECTRONIC COMPONENTS?
1.Moisture barrier bags
❊Method: The moisture sensitive components are packed in sealed moisture barrier bags, with desiccants and humidity indicator card (HIC) inside, users identify the ambient humidity in the sealed packages by checking the color change of the dots on the car.
❊Disadvantage: Moisture barrier bags + humidity indicator cars + desiccants + manual work = consumables, leakage risk, high cost.
2.Nitrogen cabinets
❊Method: The moisture sensitive components are stored in nitrogen purge cabinets or compressed air to meet low humidity storage
❊Disadvantage: Nitrogen filling = continuous N2 consumption, high co
3.Electronic dry cabinets
❊Method: The moisture sensitive components are placed in an electronic dry cabinet, just plug in, the machine will automatically work, and reach very low humidity.
❊ Advantages: No consumables, no manual work, no nitrogen consumption, environmental, only a little bit of electricity needed.
