High temperature resistance, good quality, not easy to oxidation, not easy to deformation, widely used, simple to use 2. Easy to weld, real material. Name: Double-Sided PCB Board Size:7*9CM Color:Green Hole distance: 2.54mm Aperture: 1.0mm Thickness: 1.6mm Material: FR-4 glass fiber board Product introduction: This is a universal design of the circuit board, usually its board. It is covered with standard IC spacing (2.54MM) round individual pad, looks like the whole board is filled with holes, So also called "hole hole board" compared to the professional PCB printed circuit board, hole hole board It has the characteristics of low cost, convenient use and flexible expansion. Nicknames: Multipurpose board, experimental board, learning board, hole board, lattice board. Product function: 1, the development board is used for learning, the development board for learners to design the commonly used circuit learners do not need Make their own circuit boards, do not have to purchase devices and welding transfer. 2, the development board is mostly related to the microprocessor, the development board will be designed for a variety of typical applications Some typical programs that use learners to test and learn. 3. Development board can effectively improve learning efficiency and shorten R&D progress. Welding skills: 1. Determine the preliminary layout of power supply and ground wire. 2. Be good at using the pins of components. 3, good at setting the jumper spear. 4, good at using the needle arrangement. 5. Cut off copper foil when needed. 6. Take advantage of dual panels.
