The 1943 patent for the printed circuit board goes back to the Austrian electrical engineer Paul Eisler. However, this technology did not catch on at first. It only became more popular at the beginning of the 1950s and was constantly developed and improved.
Today, it is impossible to imagine electronic devices without printed circuit boards and they are used in a wide variety of applications.
Our FR4 - printed circuit boards made of fiberglass fabric are manufactured using the environment-friendly HASL (Hot Air Solder Leveling) process. In this process, the addition of lead to the tin for the surface of the printed circuit board is completely eliminated.
This manufacturing method is suitable for any standard SMD. It allows good solderability and has good reflow properties.
In cooperation with our experienced overseas engineers, we develop customized solutions for desired electronic circuits, please feel free to contact us.
