Drop Impact Tester for Anti-Static Bags per ASTM D1709

Why Impact Resistance Testing is Essential for Anti-Static Bags for Electronic Components

Anti-static bags for electronic components serve as the first line of defense against static electricity and physical damage. Electronic components are highly sensitive; even minor impacts can lead to failures, compromising device functionality and reliability. The mechanical integrity of the bag’s plastic film is critical to withstand accidental drops, impacts, or pressure during transportation and storage.
Using a drop impact tester according to ASTM D1709, manufacturers can accurately measure the impact resistance of these films. This ensures that the anti-static bags will not tear or puncture under typical handling conditions, safeguarding sensitive electronics and reducing product failure rates.

Overview of ASTM D1709 Drop Impact Testing Methods

ASTM D1709 outlines two standard methods to measure film impact resistance:
Test Method A uses a hemispherical dart (38.1 mm diameter) dropped from 0.66 meters. This is suitable for films needing missile weights of about 50 g to 6 kg to cause failure.
Test Method B employs a larger dart (50.8 mm diameter) dropped from 1.52 meters, for weights ranging from 0.3 kg to 6 kg.

Both methods provide standardized, reproducible conditions to evaluate impact resistance, though their results are not directly interchangeable.

Conducting Accurate Tests for Anti-Static Bags

To obtain reliable and meaningful results when testing anti-static bags, follow ASTM D1709 protocols:

• Specimen Selection: Use samples representative of production, free of defects like pinholes or wrinkles.
• Conditioning: Maintain specimens at 23 ± 2°C and 50 ± 10% relative humidity for at least 40 hours prior to testing to stabilize film properties.
• Equipment Setup: Choose the appropriate dart size and set the drop height precisely. Ensure consistent dart impact at the center of the clamped specimen.
• Testing Technique:
  • Staircase Method: Adjust dart weight incrementally based on specimen pass/fail results to determine the weight causing 50% failure.
  • Alternative Method: Test groups of ten specimens at fixed weights, varying missile weights between groups to map failure percentages.

These procedures deliver accurate impact resistance data crucial for qualifying anti-static bags.

Special Considerations for Anti-Static Bags

Testing anti-static bags for electronic components presents unique challenges:

• The plastic films used must provide both static dissipation and mechanical protection, so impact resistance testing must be complemented by electrostatic discharge (ESD) testing.
• Anti-static films may behave differently under impact due to additives or special coatings, so manufacturers should test multiple samples from different production batches to ensure consistent quality.
• Packaging applications often require compliance with additional standards beyond ASTM D1709, so impact resistance results should be integrated into a broader quality control framework.
