SDC Series Dry Cabinet with 2 Glass Doors, 24.8" x 34.6" x 36.58", ≤10% RH

StatPro Dehumidifier Dry Unit's Working Principles

StatPro Auto Dry Box, Dry Cabinet & Electronic Desiccators utilizes multi-porous molecular sieves in its dehumidifier core units and involves two stages. The first stage is the “Adsorption Stage” and the next stage is the “Exhaust & Regeneration Stage."

Dehumidifier Core Unit Adsorption Stage:

During the adsorption stage, the dehumidifier core unit's valve doors open on the inside and seal from the outside. This allows moisture inside the dry cabinet to be naturally adsorbed into the multi-porous molecular sieves in the core unit. During this stage, the core unit performs its desiccating function without any power consumption and will continue to desiccate even when the power supply is interrupted. Operational light indicators inside the cabinet will remain off during this time.

Dehumidifier Core Unit Exhaust Stage:

The core unit valve doors automatically seal inside the dry cabinet and open vents outwards to exhaust & expel the moisture absorbed from inside the Dry Box. During this stage, operational indicators will be on.

Moisture adsorbed by the multi-porous molecular sieves is expelled by the drying unit and the core unit is automatically regenerated for moisture adsorption.

There are no water tanks to empty, desiccant bags & packs to replace, or any other maintenance required by the user. Simply plug in the power cord, set the desired RH level and the StatPro Auto Dry Box will begin its dehumidifying operation cycle. The core unit performs the moisture adsorption process without any power required. Thus is a safe and clean environment.

Alternative Drying Solution Replacing Traditional Methods

Moisture sensitivity in Surface Mount Technology (SMT) is a constant problem as the industry utilizes high temperature reflow process.

Many serious manufacturing defects and failures may not show up until the product is in the field are resulted from improper storage and handling of moisture sensitive components and PCBs during the assembly process. Without proper moisture control, field failures will occur.

These are important factors for manufacturing industries where product reliability must be tightly controlled such as automotive, defense, medical devices, aeronautics & aviation industries.

Why do you need a StatPro Dry Tech Fast Super Dryer?

As development cycles shorten, invention of ever-smaller device, innovative use of new materials and larger wafer chip development, all contributing to a rapid increase of moisture-sensitive devices and higher levels of trace moisture sensitivity during reflow process. Internal component damage due to trace moisture expansion, will result in MSDs during surface mount reflow process. Storing moisture sensitive devices (MSD) and components in StatPro Dry Tech's Fast Super Dryer JEDEC Dry Cabinet will provide extended floor life and will prevent moisture expansion, popcorning, intermetallic growth, oxidation, solderability and other moisture related problem from occurring in the first place.

How does trace moisture affect SMT production?

• Trace moisture causes failures to components and PCBs during high temperature reflow process. When absorbed moisture rapidly expand from high temperatures, common internal component damages and failures such as micro-cracking, blistering, popcorn effects will occur in moisture sensitive devices, packages and components.
• Printed Circuit Boards are hygroscopic. Absorbed moisture will lead to delamination in PCB when moisture inside the layers causes expansion during the reflow process.

Moisture Problems Solved with StatPro’s Ultra-low Humidity Storage Dry Cabinet

StatPro Dry Tech’s JEDEC dry cabinets, dry boxes, and desiccators will provide ultra-low humidity storage environment conforming to IPC/JEDEC J-STD 033 & IPC-1601, storage and handling standards for MSDs and PCBs.

Similar to an oven, StatPro Dry Tech Fast Super Dryer also dehumidifies during storage, providing alternative drying methods optimal for removing moisture in all moisture sensitive materials in SMT production, solving all moisture damage problems during reflow process.

• Baking process uses high temperature to dry PCBs and will cause breakdowns of protective coatings, lead oxidation, intermetallic buildup and reduces solder ability of circuit boards.
• Nitrogen and clean dry air purge is costly and will only force moisture from the storage cabinet providing a humidity controlled environment. Nitrogen purging will not dry or remove moisture that has absorbed into the moisture sensitive materials, components or devices.

Additional Fast Super Dryer applications:

• When components are removed from moisture barrier bags, StatPro’s ultra-low humidity storage cabinet will stop floor life clock for all IC packages such as:
  • Dual-in-line: Flatpack, SOIC, SOJ, TSOP, SSOP, TSSOP, QSOP, VSOP, DFN
  • Quad-in-line: PLCC, QFP, LQFP, PQFP, CQFP, MQFP, TQFP, QFN, LCC, MLP, PQFN
  • Grid arrays: PGA, BGA, LGA, FBGA, LFBGA, TFBGA, CGA, CCGA, μBGA, LLP
• Drying and storage of multi-layer PCB and PWB before and after mounting, including dual side boards awaiting second side reflow.
• Moisture controlled storage with drying/desiccating capabilities for PCB pattern film/prepreg, quartz, fiber optics, CCDs, etc.
• PP plate, Prepreg, Solder Paste, Semi-mounted PCB, Mounted PCB, Die Cast & Mold compounds, Bonding materials, Fluorescence powder, LCG board, Wafer, CCD, Condenser, Oscillators, etc.​

Features of StatPro Fast Super Dryer’s Ultra-low Humidity Dry Storage:

• Fast recovery times in ambient temperature and pressure (NTP) conditions without using costly nitrogen (N2) or dry air purging. Solving all moisture related problems while increasing yield rates.
• Moisture is removed and expelled from the cabinets by the use of desiccant dehumidifiers which automatically regenerates. No fans are required to ventilate.
• Dual hydrometer sensor designs with independent hydrometer monitoring relative humidity levels inside the cabinet.
• Provides moisture sensitive devices infinite floor-life meeting IPC/JEDEC J-STD 033 standards.
• StatPro’s dry cabinets will provide storage environment meeting IPC 1601 standards optimal for multi-layer Printed Circuit Board / Printed Wire Boards.
