Our HDI Capacities

HDI PCB is characterized by thin lines, tighter space, and more intensive wiring, which allows faster connections while reducing the size and volume of the project.

Back Drilling

A technology to disconnect part of the plated through-via from other internal layers, which many of our competitors cannot do.

Buried capacitor

We can improve the integrity of digital power supply and signal, and reduce the AC impedance between power supply and ground.

Hole Tolerances

We maintain stringent hole tolerances and locations to insulate through-via connectors and prevent signal leakage.

LDI Technologies

In terms of performance, LDI has better analytical ability than traditional machines, and has higher stability and precision.

On-going Production Quality Control

At YooProo, our quality management system is paramount to our production process. Our factory is certified with ISO9001/14001, IATF16949, and UL Verified, and our QC team is meticulously monitoring the process, performing sampling tests, and sorting out any defective boards. We strive to ensure that the goods you receive are safe and meet the 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.

Professional. Certified. Innovative.
