Quality Control

Guaranteed quality, every time.

We at YooProo are dedicated to providing our clients with PCBs that meet or exceed all applicable global norms.

As a reliable supplier, we never deign to deceive anyone or cheat; We are committed to providing you with honest and reliable products.

Every single PCB produced by YooProo's factory has undergone rigorous quality control inspections.
We use a state-of-the-art equipment to ensure that every procedure is quick, precise, and measurable.

Pre-production Quality Control

Excellent Raw Materials for a Successful Brand

We take full responsibility for all aspects of your PCB. As a carefully reviewed supplier, it is our top priority to ensure that you always get the products you ordered. In addition, we will compare the materials with the approved samples before production to ensure that the final products meet our company's and customers' expectations.

In-house Sampling

We have a quality control team to create test samples from raw materials within a given time to ensure that the materials and quality of products produced meet the specifications.

Trial Production Examination

When placing large orders, we must ensure that our materials are of the highest quality. Given this, our OC team will repeat the inspection of PCB materials and samples according to the quality checklist.

On-going Production Quality Control

Our quality management system governs the entire production process. YooProo factory is ISO9001/14001, IATF16949, UL Verified. Our QC team closely monitors everything, from the process to sampling tests and sorting out defective boards. To guarantee that you receive safe and quality goods, we require that our goods adhere to standards set by your government.

1. Manual Visual Inspection

To magnify glass or microscope to identify short circuits, open circuits, or some appearance defects on PCB.

Confirm component mounting on PCB through human vision and comparison.

This technology is one of the most widely used online testing methods.

Low pre-cost and no test fixture are its main advantages.

2. AOI Inspection

Inspection of the circuitry against digital“images”(based upon data) to verify that it is free from such defects as shorts, opens, etc.

A non-electrical, test fixture-free online technology.

With high detection success rate, easy to follow detection.

Fast shooting by AOI high-definition image camera can fundamentally solve the problem of short circuits, ajar, temporary, and other hidden dangers.

3. Function Test

Our earliest automatic test principle, which can be completed by various test equipment.

Our primary test method for specific PCBs or specific units.

Mainly two types: Final Product Test and HotMock up.

To simulate the use of the final product and to reproduce the product's performance in this process.

4. Flying-Probe Tester

Easier and faster to program than the traditional ICT testing method.

In addition, we can complete the debugging of the flying pin test in a shorter time than the conventional ICT test.

The fastest time to market (TimeToMarket) tool automatically generates tests, has no test-rack cost, good detection, and easy programming.

5. PCB X-ray Detection

Used in PCB inspection and high-difficulty processes, such as BGA and pop process design.

Its principle is to irradiate and project through X-ray, similar to manual X-ray photography, to detect the internal defects of the PCB board.

Good detection ability for blind holes and other processes

6. MDA

A good tool for diagnosing manufacturing defects in high production/low mixing.

Easy to follow detection and fast and complete short circuit and open circuit test.

However, functional testing cannot be carried out. Test-rack is required, and the testing cost is high.
