Moisture Barrier Bag Dri-Shield 3400, 100 x 100 mm, ESD Shielding, Pack of 100 - Desco D3444

Moisture sensitive SMD components must stay dry and protected from electrostatic discharge until placement. The Desco Dri-Shield 3400 (SCS product line) does both: the metal layer shields discharges to below 10 nJ, and the moisture vapour transmission rate is < 0.0003 g/100 in²/24 h. Size 100 x 100 mm, suited to single components, reel sections and small assemblies.

Key benefits

• Dry packing done right: MVTR < 0.0003 g/100 in²/24 h, suitable for dry packs per IPC/JEDEC J-STD-033
• ESD protection: discharge shielding < 10 nJ per ANSI/ESD STM11.31, EMI attenuation 45 dB
• Dissipative inside and out: 1 x 10⁴ to < 1 x 10¹¹ ohms, the bag can be grounded on a grounded surface or by a grounded operator
• Thin yet strong: only 4 mil thick, average puncture strength above 20 lbs (88 N), tensile strength 41 MPa
• Traceable: ESD symbol, moisture warning symbol and lot code printed, free of amines, silicones and heavy metals

Applications

Dry packing of moisture sensitive devices (SMT), PCBs and assemblies for storage and shipping. A complete dry pack consists of moisture barrier bag, desiccant and humidity indicator card. The bags are heat sealable and suitable for vacuum packaging.

Standards

ANSI/ESD S20.20, ANSI/ESD S541, ANSI/ESD S11.4 Level 1, IPC/JEDEC J-STD-033. Lead-free, RoHS 2, REACH and Conflict Minerals compliant.
