What is Climatest Symor® dry cabinets for electronic integrated chips, electronic moisture-proof cabinets?

Climatest Symor® dry cabinets for electronic integrated chips, is an enclosure with electronic humidity control that automatically maintains a stable relative humidity (RH) value, the dry cabinets for electronic integrated chips come in different sizes and shapes, it can keep <10%RH low humidity environment reliably, with accurate RH control, just connect to your power supply, and set RH value on the LED controller, it will automatically work.

How do dry cabinets for electronic integrated chips effect 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 dry cabinets for electronic integrated chips 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.

dry cabinets for electronic integrated chipscan maintain <10%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.

Why do you need a dry cabinets for electronic integrated chips to store SMD?

MSD devices are generally integrated circuits, composed of different components, these components are assembled through paste, this inevitably causes gaps among components, the gaps are the main factor of MSD dampness, moisture will penetrate, and gradually into the SMD, when the penetration reaches a certain extent, SMD get damp and failed.
MSD low humidity storage , aims to control the SMD workshop life, dry cabinets for electronic integrated chips provide an effective storage solution, the dry cabinets for electronic integrated chips performance determines the SMD storage effect, a professional dry cabinets for electronic integrated chips should achieve low humidity, antistatic and fast dehumidifying functions.
SMD level determines the required humidity level. In the current SMD level, the commonly used storage humidity is 20%, 10% and 5%RH.
Climatest Symor® dry cabinets for electronic integrated chips adopt Switzerland imported temp. & RH sensor, the error is +/-2%RH, with high precision and high stability, humidity is adjustable, air-tightness is excellent.

Application of dry cabinets for electronic integrated chips

dry cabinets for electronic integrated chips are essential in electronic/semiconductor manufacturing industry, it is the OPTIMAL storage solution 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.

<10%RH Series dehumidifying speed:

Open door 30 seconds and then closed, the humidity will recover to <10%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 car (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 cost.

3.Low humidity storage cabinets
❊Method: The moisture sensitive components are placed in a low humidity storage 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.
From above comparison, dry cabinets for electronic integrated chips bring you higher efficiency and lower cost, it is the most cost-effective option in the long run.

We provide dry cabinets for electronic integrated chips solutions to below industries:

Advantages of dry cabinets for electronic integrated chips

What is the difference between dry cabinets for electronic integrated chips and nitrogen cabinets?

1.Working principle
Low humidity storage cabinets use physical humidity absorbing, the core part is dry unit, the dry unit automatically adjusts the humidity absorbing and exhausting circulation processes, there are different RH ranges for your selection, such as 20-60%RH/10-20%RH/<10%RH/<5%RH/<3%RH, it depends on your specific demands.
Nitrogen cabinets use N2 gas purge, the N2 gas filled in push the interior air outside, then the RH lower to the setting value, there is a N2 flow-meter, magnetic valve and N2 module equipped on the nitrogen cabinet for control purpose, the humidity is 1-60%RH adjustable, but it needs continuous N2 supply, the cost is high.

2.Dehumidifying speed
The nitrogen cabinets dehumidifying speed are faster than the dry cabinets for electronic integrated chips, when the N2 rush into the cabinet, the interior RH can reach 1%RH within several minutes, however, the electronic dry cabinet have to experience RH absorbing and exhausting processes, it is slower, normally within 10-30 minutes, depending on specific RH range.

3.Application
If the products are just humidity sensitive, dry cabinets for electronic integrated chips are the best choice, if the products are both humidity sensitive and oxygen sensitive, like copper, crystal, silver, then N2 cabinet is better.
