Recruitment pcb

There are many kinds of single-chip microcomputer, and there are many applications! If you are engaged in small household appliances (rice cookers, vacuum cleaners, flashlights, etc.) single-chip computer program development. ), which requires less MCU internal programming and more hardware. Small household appliances often use 8 bits or 16 bits. Now chip manufacturers often provide some sample programs for engineering R&D personnel to refer to! Peripheral circuits have to be carefully studied, such as how to supply power to MCU (generally, single chip computers can't have clutter, and often a short peak will cause the chip to burn out). As for PCB, this is very basic, but it is definitely not as simple as learning to draw PCB at school. You have to consider the overall layout, whether the supplier's production process can be achieved, and pay attention to the safe distance when assembling with high pressure! In the early stage of study, I studied the MCU of a certain manufacturer, such as NXP, ST, Renesas, Atmel, Microchip, etc. If every manufacturer studies it, it is estimated that the energy is not enough.
