Static-Safe Desiccator Construction

Even the slightest static discharge can spell disaster for today’s delicate components. Because the dangers of ESD (electrostatic discharge) are amplified in a low humidity environment, Terra strongly urges that you consider these measures as part of your static control program.

Static electricity is an excess or deficiency of electrons on a surface. The total number of deficient or excess electrons determines the charge on that surface. A surface exhibiting an excess of electrons is charged negatively, and an electron-deficient surface is charged positively.

Although static electricity has plagued the semiconductor manufacturing industry ever since the advent of integrated circuitry, its effects pose especially serious problems to today’s miniaturized, sophisticated, and expensive components. These devices can be seriously damaged or destroyed by charges much smaller than a person can typically detect.

How are Electrostatic Charges Generated?

Electrostatic charges are usually generated by friction between and/or separation of two dissimilar materials, at least one of which is a nonconductor or a poor conductor of electricity. The accumulated charge (static) resides on the surface of, rather than within, the charged nonconductive object.

Electrostatic discharge (ESD) occurs when an accumulated charge (which may be present on an operator, the operator’s clothing, or on any other non-conductive object) is discharged through a conductor (which may be part of a wafer, a chip, or a packaged device), and it may occur whenever the electrostatic potential corresponding to accumulated charge is great enough.

Acrylic or Static-Dissipative PVC Shell

Acrylic, the most common plastic used in storage enclosures, is a prolific static generator. The act of cleaning an acrylic desiccator with a cleanroom wiper is enough to generate surface charges that can discharge onto semiconductor components. One way to avoid potentially disastrous static damage is to select Static-Dissipative PVC.

This material not only dissipates static charges safely, but it also eliminates the particle attraction that static charges create. Surfaces stay clean, inside and out, making this material perfect for use in Class 1 cleanrooms.

Because static-dissipative PVC is transparent and highly durable, it can be used in place of acrylic in nearly any application, desiccators included. It features a surface resistivity of approximately 107 ohms per square, placing it in the "dissipative range". It is completely noncontaminating—with no measurable outgassing—and it resists a wide range of chemicals.

Note: To protect Static-Dissipative PVC surfaces, desiccators made of this material must include stainless steel shields installed at the bottom of each chamber.

Fabricated of clear acrylic or Static-Dissipative PVC, Static-Safe Storage Systems provide full 360-degree viewing of stored components. Solvent-welding and contamination-free materials guarantee a clean environment free of outgassing. Static-Safe desiccator cabinets house from one to four compartments of two different widths (see dimensional chart). Because our desiccator components are standardized, you can easily replace a damaged door.

Stainless Steel Slide-Out Drawers and Runners

The system's 304 stainless steel trays create a Faraday cage that shields stored materials against electro-static discharge (ESD). They can be easily removed and used as handling trays, eliminating the need to touch—and possibly to contaminate—sensitive microelectronic components.

The trays mount easily into the system's runners to become slide-out drawers. Runners feature an easy-glide suspension system that supports up to 40 lbs (18.1 kg). when fully extended and allows full access to every inch of drawer space. Two-drawer compartments provide 5.25" (133 mm) of clearance and include 5"-deep (127mm) trays suitable for 4" (102 mm) waffle packs; three-drawer compartments provide 3.1875" (81 mm) of clearance and are available with 2"-deep or 3"-deep trays, suitable for 2" (51 mm) waffle packs.

Stainless steel inlays, included in Static-Safe desiccators with 2"-deep trays, are slotted every .375" (10 mm) to permit easy insertion of stainless steel dividers (order separately). Inlay packages allow front-to-back storage of up to 192 2-inch waffle packs (with retaining dividers) in small trays, and up to 240 2-inch waffle packs in large trays.

For enhanced static-control, select a Static-Safe Desiccator made of static-dissipative PVC, which dissipates surface charges that can attract and hold particles.

Although the Static-Safe desiccator configuration does not form the closed box that Faraday described, both shield and tray are at the same potential and no electric field can exist within the volume they enclose. This effect can be demonstrated simply by directing an electrical discharge at the opening between the shield and the tray. The discharge never enters the cavity, and any stored materials inside remain completely shielded from the effects of the discharge.

Faraday Cage Design Shields against Eletro-Static Discharge (ESD)

ESD safe desiccator cabinets include ground slide-out trays to create a Faraday cage, shielding sensitive microelectronics in storage from electro-static discharge (ESD).

Sliding Trays for Barcode Scanning

Terra's static-safe desiccator cabinets have removable sliding trays capable of neatly storing sensitive elctronics and allowing for easy inventory management. Barcodes can be added on the lip of the tray for efficient inventory management.

Removable Desiccator Trays

Terra's desiccator trays organize sensitve electronic materials seamlessly. Sliding trays can be easily removed and replaced into the desiccator.

Built-in Plenum Distributes Dry Gas to Each Chamber

Manual flowmeter or automated system controls nitrogen flow rates to maintain RH across entire cabinet. Built-in plenum distributes dry gas to each chamber.

High Caliber Hardware

Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.

Reinforced Doors with Non-adhesive Gaskets

Stainless steel door frames extend desiccator life; one-piece fused gaskets are non-outgassing, will not creep or sag

Desiccator Plenum Chamber For Uniform Gas Distribution

Multi-chamber desiccator cabinets include a perforated plenum to minimize back fill, ensure uniform gas distribution to all chambers and increase cabinet strength

Durable Embedded Static-Dissipative Layers

Terra's SDPVC features bonded dissipative layers that resist abrasion. SDPVC desiccators retain their surface resistivity of 106 - 108 ohms/square indefinitely (unlike spray-on coatings that can wear off after a few years), protecting your materials against ESD damage. Further, the control of static charges eliminates particle attractions, helping maintain clean surfaces.

Highest Standards For Desiccators and Electronic Components

Terra’s desiccator cabinets and RH control systems are designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.

Rapid Drying of Hygroscopic Material

Terra's gas-purged desiccators utilize a rapid flow of inert nitrogen to quickly dry hygroscopic samples and components

Doors - The First Failure Point of a Desiccator Cabinet

Terra’s stainless steel door frames eliminate the need for internal reinforcements, which create particle surfaces and compromise cleaning. Unlike other doors with glue-on anti-bow pieces, Terra’s doors use no adhesives. This eliminates particle traps, sources of outgassing—and extends the strength and service life of the desiccator.

Automatic Relief/Bleed Valve

Terra's Automatic Relief/Bleed (RB) Valve opens up at 0.01 PSI, relieving overpressure that could damage desiccators; also works as a check valve to prevent influx of outside air.
