Definition of Climatest Symor® ultra low humidity dry cabinets, dry storage cabinets?

Climatest Symor® ultra low humidity dry cabinets, also called dry storage cabinets, is an enclosure with electronic humidity control that automatically maintains a stable relative humidity (RH) value, the ultra low humidity dry cabinets come in various shapes and sizes, it can maintain a <5%RH low humidity internal environment, with precise RH control, but do require a constant power source.

How do ultra low humidity dry cabinets influence the SMT production?

MSL components, like IC, BGA, PCB, are very sensitive to moisture, these components have strict requirements for the storage environment, unlike the civilian moisture-proof dry boxes, the ultra low humidity dry cabinets can reach a very low humidity value, the dehumidifying and recovering speed is super fast, the whole cabinets are ESD safe.
During reflow process, trace moisture penetrate into the IC packages, the moisture pressure rises due to heating, the absorbed moisture expand quickly inside, this result in invisible damages, like wiring failure, popcorn and micro-cracking, even cracking to the 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.

Ultra low humidity dry cabinets can maintain <5%RH, that effectively eliminate the risks of failures result from improper storage during assembly process. 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.

Ultra low humidity dry cabinets application

Ultra low humidity dry cabinets are a must-have in electronic/semiconductor manufacturing industry, it is the excellent storage expert for:
※ PCB assembly, IC chips, LED, SMD, SMT, tape & reels, printed wiring boards(PWB), polymide film, feeders.
※ Capacitors, ceramic parts, connectors, switches, welding bar.
※ MSL components that have been partially assembled.
※ Moisture-absorbing materials, such as epoxy, resins, adhesives.

Moreover, cleanrooms have very strict hygiene requirements, the standard models don’t match, Climatest Symor® also supplies stainless steel (SS) dry cabinets and stainless steel (SS) nitrogen cabinets, both are customized according to customers’ specific demands.

<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.
