Quality Inspection-ZITOLK ELECTRONICS LIMITED

QualityPromise

It is our persistence as before. Adhering to authentic products, ensuring product quality, and following the process are the guarantees that support us to become a world manufacturing service provider. From the supplier management audit, the check of the order form and the delivery order, the regular comparison, the appearance inspection, etc.,
ZITOLK Technology always follows the established procedures and steps, focusing on every detail to ensure that the electronic components are in compliance.

01Check item

Checking of pre-order and delivery list, regular comparison, visual inspection (burning, bending, oxidation), quantity

Disposal of environmentally friendly products such as RoHS products (at the time of label verification)

Inspection records: Yes (stored for 5 years)

Batch inspection record: Yes

Qualified Inspectors: Only qualified personnel who meet our regulations can be inspected. When working, wear anti-static clothing and anti-static slippers, install an anti-static wrist strap on the anti-static mat, and do not touch the container with bare hands

02Warehouse management

How to store inventory: The storage location is an ordinary air-conditioned office in an anti-static room.

Model and storage quantity control: recorded in the inventory management ledger

Overdue management law: two years in principle.

Operations such as storage expiration: stored on shelves dedicated to defective products. Defective product inventory is accounted for when it occurs, and it is discarded at the end of the fiscal year one year after the occurrence.

Items to check when shipping: Match the receiving receipt with the product name, quantity, and packaging specification with the actual product.

03Shipment inspection

How to Check: All Checks

Inspection items: accept inspection confirmation, match the actual product, address confirmation, other confirmation items (if any)

Inspection records: Yes (stored for 5 years)

Packing materials: anti-static bag, use vacuum packer, vacuum machine

3. Incoming integrated circuit testing and screening service
Level 1, Authenticity Inspection (AIV for short): determine whether the device complies with specified documents or customer-specific requirements;

Level 2, DC characteristic parameter test (referred to as DCCT): also known as static parameter test;

Level 3, key function test (KFT): also known as main function test, is a dynamic test method;

Level 4, all functions and characteristic parameters test (FFCT for short): test all functions and parameters of the chip;

Level 5, AC characteristic parameter test (ACCT for short): test and analyze the transient alternating characteristics of the device;

Level 6, special case test ratio analysis (SEAT): to study the stability of devices working under special cases.
