Integrity of packaging, consistency of internal and external packaging and correctness of packaging contents such as moisture-proof bags, desiccants, moisture-sensitive cards, etc.

Check the brand, model, quantity, batch, date of manufacture, lace of origin, moisture sensitivity level and environmental label, and compare the specifications with company's internal database.

Check whether the three packaging methods of tape, tray and tube are in compliance with specifications and industry regulations.

Measure whether the main external dimensions of the device are within the tolerances of the specification.

Observe the pin terminals and BGA balls under a magnifying glass to confirm that their packaging are consistent with the specifications and to observe whether there are any scratches, deformations, missing, oxidation and other abnormalities.

The insulation resistance test is an electrical test which uses a certain type and level of voltage to measure insulation resistance in Ohm`s. Typically, it is used to measure the insulation resistance and withstanding voltage of MLCC.

Discrete test mainly measures electrical parameters of IGBT, MOSFET and Diodes. It is also used for Open/Short Test and I/V curve analysis.

LCR meter is used to measure the resistance, capacitance and inductance of a conductor. Meanwhile, it also measures parameters of |Z|/|Y|/D/Q/X/B/∅ etc.

X-Ray fluorescence is used for conducting material analysis to determine the elemental composition of a material sample. It is most commonly applied to determine the amounts of controlled elements specified within the Restriction of Hazardous Substances (RoHS) Directive.Meanwhile, it can also identity the elements composition in specific location when comparing to golden sample or trelated datasheet.

X-Ray test is a non-destructive radiological inspection for internal construction verification. It’s a screening method used to verify die presence, bond wires, leadframe and the consistency from one component to the next or known good sample.
