Faraday Cage Integrity

Flexible Packaging Built for Electronics & Semiconductor

A single electrostatic discharge (ESD) event — invisible at under 3,000 volts — can destroy integrated circuits, with failure rates reaching 10⁻⁶ per device-hour in unprotected environments. As an ESD shielding bag manufacturer and moisture barrier packaging supplier serving PCB fabricators, IC packaging houses, and EMS providers, we produce static shielding bags, moisture barrier bags (MBB), desiccant pouches, and cleanroom vacuum bags with batch-level surface resistivity testing — the last line of defense between your components and latent field failures.

Electronics & Semiconductor Packaging

Shield against static. Block moisture. Survive the cleanroom — packaging engineered for electronics that cannot afford a single failure.

01

ESD Protection Across the Full Spectrum

Surface resistivity from 10³ to 10¹¹ Ω/sq covers conductive, static dissipative, and insulating classes, tested per batch with four-point probe per ANSI/ESD STM11.11.

02

Moisture Barrier for MSL Devices

MBB structures with OTR < 0.005 cc/m²/day and WVTR < 0.01 g/m²/day prevent the “popcorn effect” (moisture-induced IC delamination during reflow), with humidity indicator card (HIC) windows for at-a-glance verification.

03

Cleanroom Compatibility

ISO Class 5 (Class 100) compatible vacuum bags with low outgassing (< 0.1% TML per ASTM E595) and particulate-controlled surfaces for wafers, optics, and MEMS sensors.

Electronics & Semiconductor Packaging Formats We Manufacture

Every electronic component — from a bare PCB to an MSL 3 IC — has an optimal format defined by its ESD sensitivity, moisture sensitivity level, and handling environment. As an OEM electronics packaging manufacturer with in-house multi-layer lamination, we are fully equipped to fulfill your custom flexible packaging requirements across all dimensions and specifications. Below is our complete capability matrix.

Recommended Pouch Optimal Application Areas Material Structures Key Technical Spec
ESD Static Shielding Bag PCB assembly, IC chips, BGA, wafers 3-layer polyester / AL / PE Surface resistivity 10⁴–10¹¹ Ω/sq; Buried metal Faraday cage
Moisture Barrier Bag (MBB) MSL 3–6 devices, JEDEC trays AL / VMPET / PE multi-layer OTR < 0.005 cc/m²/day; HIC window; MIL-PRF-81705 Class I
Aluminum Foil Desiccant Pouch Bare PCBs, IC trays, wafer cassettes Triple-layer AL composite WVTR < 0.01 g/m²/day; Integrated desiccant; 4–6 mil puncture-resistant
Anti-Static Dissipative Pouch Resistors, capacitors, connectors Amine-free pink PE Surface resistivity 10⁹–10¹¹ Ω No corrosive outgassing RoHS
Cleanroom Vacuum Bag Wafers, precision optics, MEMS Nylon / PE vacuum sealable ISO Class 5; TML < 0.1% (ASTM E595); Particulate-controlled

Manufacturing & Material Capabilities

No pinholes. No ink wear. No audit surprises — engineered for electronics that demand absolute ESD and moisture protection with full regulatory traceability.

Solvent Free Anti Static Lamination

Solvent-Free Anti-Static Lamination

In-house lamination eliminates pinhole risk that destroys Faraday cage integrity; surface resistivity controlled at every production stage.

Buried-Ink Gravure Printing

Buried-Ink Gravure Printing

ESD warning symbols (ANSI/ESD S8.1), MSL labels, and barcodes printed on film before lamination and buried under a protective PE layer — preventing ink abrasion particulate in cleanroom environments.

Audit Ready Test Data

Audit-Ready Test Data

ANSI/ESD S20.20, IEC 61340-5-1, MIL-PRF-81705D, JEDEC J-STD-033D, RoHS, REACH; third-party ISO 17025 reports for surface resistivity, WVTR, OTR, and outgassing before first shipment.

Electronics & Semiconductor Packaging FAQs

Clear answers about electronics & semiconductor packaging, customization, pricing, shipping and after-sales support.

Q1. Do you test surface resistivity per batch?

Yes. Every batch undergoes four-point probe surface resistivity testing per ANSI/ESD STM11.11, with test certificates shipped with the goods.

Q2. Can you meet MIL-PRF-81705 requirements?

Yes. Our moisture barrier bags are MIL-PRF-81705 Class I compliant, with HIC windows and desiccant integration options.

Q3. Do you support NPI-scale trial runs?

Yes. Our flexible MOQ is evaluated per project, supporting engineering validation runs through million-unit production — no re-qualification when you scale.
