Circuit Board Production

Our circuit boards are produced by us. If you are interested in the process then continue reading.
In the Gallery (Circuit Board Production), you can have a look at the pictures, which were made during the process.
After designing a circuit diagram, a model of the conductor tracks has to be printed on a transparency. It is used to exposure the board to the UV light. Thereafter it is developed in a caustic soda (NaOH) bath. The board is etched in a ferric chloride bath. You have to find exactly the right time, until the conductor tracks are perfectly visible. The bores are drilled before the rivets are affixed. Then we tin coat the board chemically. Afterwards the electrical components are soldered on.
Voila – the circuit board is finished 🙂
