Electronics Industry Testing Case

Protection certification: must meet IP67/IP68 standards to ensure waterproof and dustproof performance.

Safety hazards: poor sealing may cause water ingress into motherboard or battery, leading to short circuits and corrosion failure.

Production risk: integrated metal structures require airtight seams without false seals; otherwise, products cannot ship, causing huge losses.

Project schedule: failed sealing tests in the pilot production phase can delay mass production and postpone project timelines.

Challenges in humid environments: must ensure sealing performance under prolonged exposure to moisture, water immersion, and vibration.

Safety hazards: water ingress into main control circuit boards or batteries can cause failures, corrosion, short circuits, overheating, or explosions.

Certification requirements: failure to pass IPX6/IPX7 waterproof certification will prevent product launch.

Brand impact: frequent after-sales issues severely affect user reputation and decrease brand trust.

Protection of delicate components: compact structure integrating battery, speaker, microphone, circuit board, and other delicate parts.

Daily environmental challenges: often exposed to sweat, rain, and moisture during use, requiring leak prevention.

Performance impact: poor sealing causes short circuits, corrosion, and sound distortion; moisture in batteries may lead to safety risks.

Waterproof and moisture-proof requirements: Often carried around, easily exposed to sweat, rain, and humidity.

Battery safety requirements: Built-in lithium battery with very high sealing requirements.

Product quality enhancement: Helps companies ensure compliance with the advertised waterproof rating standards.

Prevent moisture and dust from entering: If the camera housing is not properly sealed, moisture or dust may get inside, causing lens fogging or sensor damage.

Ensure electronic component stability: Electronic components are very sensitive to moisture and dust. Even a small amount of vapor can cause corrosion, short circuits, or signal interference.

Meet waterproof rating standards: Outdoor cameras usually need to meet certain protection levels before leaving the factory, such as IP65, IP66, or IP67.

Improve user experience: Poor sealing may cause blurred images or frequent malfunctions, affecting the overall user experience.

Prevent water damage: Car washing involves heavy water flow and strong splashes. If the sealing is poor, water may enter the motor chamber, battery compartment, or control board.

Ensure user safety: Water entering the circuitry may cause electric leakage, posing safety hazards to users. Therefore, reliable sealing is essential.

Market requirements: Many electric cleaning tools must meet IPX6 (strong water jet protection) and IPX7 (temporary immersion protection) standards.

Improve durability: Good sealing prevents internal metal parts from corroding, motors from rusting due to moisture, and brush transmission structures from aging or jamming, thereby greatly extending the service life.

Prevent liquid ingress: In humid or liquid environments, moisture may enter if there is leakage inside the harness or at the connector interface.

Ensure electrical safety and performance: Air leakage or water ingress may lead to short circuits, signal interference, or electrical failures.

Handle harsh working conditions: Many components in modern vehicles and equipment operate in extreme environments.

Meet industry standards: High-end electronics, automotive, and aerospace equipment require strict waterproof, dustproof, and leak-proof specifications.

Moisture and corrosion protection: Oxygen, salt (in marine or coastal environments), and industrial gases (such as sulfides) can corrode internal metal conductors, solder joints, and contacts.

Ensuring signal integrity: Moisture intrusion may alter the characteristics of dielectric materials, resulting in impedance changes, signal reflection, and increased loss.

Extending product lifespan and reliability: Airtight cables effectively prevent harmful external substances from entering, fundamentally reducing early failures caused by environmental factors.

Sealing design in product structure: If an electronic cable adopts over-molding, rubber sealing rings, adhesive potting, waterproof terminals, or similar structures, leak testing is required to verify whether the sealing is truly effective.
