Gel-Box™ with the material in the base of the box (AD Series)

Cleanroom compatible, innovative solutions for storing and transporting delicate devices

Gel-Box™ products are designed to protect and store sensitive devices and specimens during transport, processing, inspection and assembly. Devices can be loaded and removed easily using tweezers or by hand from the unique highly cross-linked Gel polymer. The degree of holding force of the Gel is depending on the tackiness of the Gel material, which is called Retention Level. The Gel material is strong in both shear and vertical directions, but weak in the peel direction, which allows parts to be easily unloaded from the Gel surface. Gel is an extremely durable and versatile material that maintains its properties between -40°C to 220°C. Minimum shelf life is 2 years.

Gel-Pak^® has applications for semiconductor devices, sensors, micromechanical devices, photoelectronics, hard drive heads, biomedical devices, and specimen storage. All Gel-Pak^® boxes are packed under cleanroom conditions, in compatible packaging.

Retention levels available are X0, X4, X5 and X8. The optimum tack level for individual parts depends on material, size, weight and surface roughness. Unfortunately there is no exact formula to calculate the retention level but general guidelines are:

• Low retention level - X0 - for highly polished surfaces
• Medium retention level - X4 - for pre-polished and/or etched surfaces
• High retention level - X8 - for rough surfaces like ceramics

Gel-Pak^® has devised an effective box system that offers a versatile selection of box materials optimized for the diverse range of applications:

• C - Conductive black polycarbonate (optimum protection against static discharges)
• AS - Clear Anti-Static plastic (optimum visibility)
• CAS - Clear Anti-Static top with conductive plastic bottom (optimum for ESD safe protection and visibility)
• T - Clear Styrene Box  for non ESD sensitive parts (most economical solution)
• CT - Conductive black plastic bottom with clear styrene lid

Gel-Box™ (AD Series)

The original and widely used Gel-Box™ is a plastic hinged box with the Gel material coated in the bottom.

Standard box sizes are shown in the table below.

Retention levels available are X0, X4, X5 and X8. The boxes are available in a variety of materials.
