What is Climatest Symor® low humidity desiccant cabinets, electronic humidity control dry cabinets?

Climatest Symor® electronic dry cabinets, or fast dehumidifying dry cabinets, are used to dry moisture sensitive components in a low humidity storage environment, it adopts the auto dehumidifying technology to maintain a humidity level from 20% to 10%RH, no nitrogen needed, no vacuum needed, users just connect the electronic dry cabinet to the power supply, then set the RH point on the LED controller, it will automatically work, the power consumption is low.

How do low humidity desiccant cabinets effect the SMT production?

Low humidity desiccant cabinets, or fast dehumidifying dry cabinets, are commonly found in SMT production line, SMT utilizes high-temperature reflow process, moisture-related manufacturing defects and failures are likely to occur in this process, which can be traced to improper storage and handling of components during the assembly process.

During reflow process, trace moisture penetrate into the IC packages, the moisture pressure rises due to heating, the absorbed moisture expand quickly inside, this results in invisible damages, these non-effective welding, like wiring failure, popcorn and micro-cracking, even cracking to the surface, are not easy to be aware in the early stage, however, these invisible, potential problems enter into the market, then faculty products return, it leads to big economic loss and low efficiency.

Low humidity desiccant cabinets, or fast dehumidifying dry cabinets can maintain any RH level within 10-20%RH, that effectively eliminate the risks of failures result from improper storage during assembly process.

Application of low humidity desiccant cabinets, electronic humidity control dry cabinets

Low humidity desiccant cabinets are essential in electronic/semiconductor manufacturing industry, it is the OPTIMAL storage solution for:
※ PCB, PCBA, IC chips, LED, SMD, SMT, EMS, 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.
※ Fiber optics such as micro-lens for WDM, and CCD, solid state image sensors.

Why do you need low humidity desiccant cabinets, electronic humidity control dry cabinets?

Generally speaking, an electronic dry cabinet is a storage machine that protects your sensitive electronic components from moisture related damages, it provides an effective humidity controlled storage solution for your moisture sensitive devices.
By storing your MSDs in Climatest Symor® low humidity desiccant cabinets, the extended floor life is ensured, the production failures, like popcorning, intermetallic growth, oxidation, solderability, are completely an ending, and greatly improve your production efficiency.
By storing your valuable components in Climatest Symor® low humidity desiccant cabinets, the moisture related defects, like fungus, oxidation, mildew, rust are disappeared, small investments are much better than huge losses.
Climatest Symor® low humidity desiccant cabinets and low humidity storage cabinet, adopt Switzerland imported temp. & RH sensor, the error is +/-2%RH, with high precision and high stability.

Moreover, cleanrooms have very strict hygiene requirements, stainless steel is known to be robust and able to withstand the most rigorous cleaning processes, Climatest Symor® also supplies stainless steel (SS) dry cabinets and stainless steel (SS) nitrogen cabinets, both are customized according to customers’ specific requirements.

10%-20%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.Dry storage cabinets
❊Method: The moisture sensitive components are placed in a dry 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 storage cabinets bring you higher efficiency and lower cost, it is the most cost-effective option in the long run.

Advantages of low humidity desiccant cabinets, electronic humidity control dry cabinets

We provide low humidity desiccant cabinets solutions to below industries:

What is the difference between low humidity desiccant cabinets and nitrogen cabinets?

1.Working principle
low humidity desiccant 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.
low humidity desiccant 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 low humidity desiccant cabinets , 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, low humidity desiccant cabinets are the best choice, if the products are both humidity sensitive and oxygen sensitive, like copper, crystal, silver, then N2 cabinet is better.
