Testing Items

Explore our specialized testing items, ensuring excellence in every component

Packaging Inspection

Verify the integrity, accurate labeling, and moisture resistance of component packaging to ensure product safety during transportation and storage.

External Visual Inspection

Thoroughly examine the external appearance of components to ensure there are no surface defects, damages, or contaminants.

Dimension Measurement

Accurately measure various dimensional parameters of components to ensure compliance with design specifications.

Scratch Testing

Conduct surface scratching tests using chemicals, cotton swabs, and blades to inspect for surface alterations, helping assess the authenticity of chip markings.

X-ray Inspection

Utilize X-ray penetration characteristics for non-destructive testing of components, observing internal structures, welding quality, and component connections to meet design requirements.

Electrical Testing

Evaluate static parameters such as Vr, Ir, Vf, RDS, Igss for discrete devices, determining compliance. Applicable to IGBT, MOS, SCR, Diode, TVS, LED, Zener, etc.

Solderability Testing

Assess terminal solderability using a dip soldering method. Evaluate wetting conditions of pins after tinning under a microscope, adhering to J-STD-002 evaluation criteria.


Dissolve the mold compound with a strong acid to expose internal grains. Examine the grain patterns under a high-power microscope and identify markings on the grains to verify authenticity.

XRF (X-Ray Fluorescence)

Analyzing the elemental composition and concentration of components by irradiating their surfaces and measuring X-ray fluorescence, for compliance checks and material analysis.

High-Temperature Testing

Assess component stability, reliability, and tolerance under high-temperature conditions by storing them for a specified duration.

Heated Solvent Testing

Immerse electronic components in a heated solvent for a specific duration, then wipe the sample surface with a cotton swab to detect the presence of coatings.

Testing Standards

Golden Sample Laboratory adheres to multiple international and industry standards to ensure the reliability and consistency of each testing project.
