We are using a substrate processing machine to make the foundation. The price is also wonderful, it is helpful to make a good base. In the future, please sell.
We will construct a circuit with a small number of parts for prototype experiments. Well, it is usual as a board. Since it costs only a few centimeters, I can not buy the board on a fixed scale. The price per unit area will be quite expensive, but it is cheaper than buying on the standard scale. It would be the best product for small circuit experiments.
