The whole board is made of thermosetting phenolic resin, and there are metal strips at the bottom of the board. Holes are punched at the corresponding positions on the board so that the components can be in contact with the metal strips when they are inserted into the holes, so as to achieve the purpose of conducting electricity. Generally, every 5 orifice plates are connected with a metal strip. There is generally a groove in the center of the board, which is designed for the need for integrated circuit and chip tests. There are two rows of vertical jacks on both sides of the board, also a group of 5. These two sets of jacks are used to provide power to the components on the board
The motherboard uses a glass fiber board with a copper foil conductive layer, which is used to fix the solderless breadboard and lead out the power terminals.
