A printed circuit board that is covered with pads according to the standard IC spacing (2.54MM) and can be plugged with components and connected as desired Compared with professional PCB board making, perforated board has the following advantages: low threshold for use, low cost, easy to use and flexible expansion Due to its insulation, no static electricity, wear resistance and high temperature resistance, bakelite board has become an insulating switch and variable resistor for electronic products, molds for machinery and fixtures on production lines, and can be used in transformers, etc It has good electrical performance at room temperature, good mechanical processing performance, and has excellent electrical, mechanical and processing properties. Paper bakelite board is a common laminate, and it is also the most widely used and largest industrial laminate in the world Suitable for college students/engineers/technicians/factories/personal DIY/electronic enthusiasts, etc Name: Single-sided tin-sprayed bakelite Board: bakelite Aperture: 1.0MM Dimensions: 7 x 9CM/ 5 x 7CM Board thickness: 1.2MM Hole spacing: 2.54MM (standard IC size) Color: Yellow Material: Copper + Organic Resin Package Contents: 30 x PCB Board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
