Conductive Mica-Reinforced PCB Rack, 20 Slots, 215 x 582 mm - Desco 237220

Larger assemblies such as control or power supply boards need more space between them and a carrier that keeps its shape. The Desco 237220 holds 20 PCBs on a 25 mm pitch. Its mica-reinforced, carbon-filled polypropylene compound stays rigid under load and drains charge with a surface resistance below 1 x 10⁵ ohms.

Key benefits

• More room per board: 20 slots of 3 x 8 mm with lead-in angle on a 25 mm pitch.
• Highly conductive: surface resistance below 1 x 10⁵ ohms/sq, volume resistivity below 1 x 10⁴ ohm cm per ASTM D-257.
• Dimensionally stable: mica reinforcement, tensile strength at break 21 MPa.
• Built to be carried: open handles at both ends.
• Heat resistant: recommended maximum operating temperature 85 °C.

Applications

Storage and transport of populated PCBs with taller components, for example after placement, before soldering, in test or in rework. For narrower boards, the shorter rack 237215 is the better fit.

Standards

EN 61340-5-1 requires tools and aids in the EPA to neither generate nor hold charge and to be at EPA ground potential. Placed on a grounded worksurface or shelf, this conductive rack meets that requirement.
