Quality

1.Well-established supplier system
2.Assure the products coming from the Global well-known traceable suppliers’ high quality products
3.Our Choice depends on supplier rating system
4.According to the supplier’s management system,

we will meticulously research and assess the supplier’s qualification to assure the source of the products. In addition,

we have our own strict and independent standards evaluation index system to weigh it.

5.Once the supplier becomes one of Yiheht Electronics Qualified Supplier, we will monitor their products quality.

According to their quality records and service, suppliers will be graded.

Quality Control Procedure:
Level 1: Visual Inspection

All supplied materials will be visually inspected by QC

Including:

1.Manufacturer Part Number, Quantities,and Date Code

2.Label and Marking inspection( Faded-Label, Damage, reprint. etc.,)
3.Appearance Inspection ( Pin Bending, Scratching, abrasion. Etc.,)

4.Tape Shape Inspection(Dent, Quantity not Sufficient.etc.,)

5.Moisture-Proof Measure Inspection(Vacuum Packaging)
6.Comparison of the Original Manufacturer Sealed Components and Faked Components)
7.Other Unconventional Visual Inspection

Level 2:Engineer Rechecking

If the quality problems are found in the inspection process, the suspect products will be handed to engineer for rechecking.

1.False Information discrimination and update

2.Label Distinguishing (Barcode Confirmation)

3.Manufacturer Logo and Date Code Distinguishing.

Level 3：

Product Test is in order to ensure the products consistent with the manufacturer specification. Samples need to be regularly t

ested to ensure the product consistency. Testing includes:
1.Unpacking Test:
2.Weldability Test

3.Surface Contamination analysis

Lab Test
Products test is carried out in the laboratory by a group of professional partners. Ensure the products consistent with the

manufacturer specification.

This test network provides us with professional technology and improved AG core competitiveness in the distribution service.
In addition, sample tests and randomly regular sample tests ensure the product consistency and strengthen the internal quality

assurance.
Test Operation Including:
a.Unpacking Test:
b.Weldability Test
c.X-Rays Inspection
d.Contamination analysis
e.DC & AC Functionality
f.Rectification and Capacitance Test
g.Electrical Property
