"Now we are inspecting the copper thickness, it is a crucial procedure in the whole PCB production flow." The engineer is inspecting the PCBs in the Physical lab at Inno Circuits Limited located in Suining, Sichuan on 18th, November.
If you walk into our plant, from lab to the productions departments, every procedure rely on the use of science and technology. Every year, we invest about 3% of the sales to research.
Using a 1000x magnifier, you can clearly see the inner wall of the drills inside the PCB, this inner wall thickness plays an important role in the electricity conductivity of the PCB. The board can be throw away immediately if it out of tolerance.
Liang Xun, as an engineer who grow up in the plant, is a typical person that are benefited by the science talent programme of Inno Circuit. He was having social practice before graduates from College of Panzhihua, then he knows what is the difference between knowledge in the book and in real conditions, thus Liang Xun is able to be well capable of working in the position after his graduating.
There are about 50 engineers that are raised this way, cooperating with colleges and shorten the circle of "getting to know what are things like in factory and what should I do."
So far, we have established national lab of electronic film and integrated components with the cooperation with UESTC (University of electronic Science and Technology of China), the research center of PCB in Sichuan province. They creates and store the power of development of Inno Circuits.
In 2017, Inno Circuit was awarded the "Science Progress of Sichuan" by its study on "every layer interconnected(ELI) in high frequency, high speed and high density PCB". It has helped to increase the sales of us in 2018 about 200K Million CNY.
Now Inno Circuit already have more than 90 patents on PCB production.
Inno Circuits, as the biggest PCB manufacturer in western China, welcome your inquiry at all time.
