PCB Assembly For Engineering Design

PCB Assembly For Engineering Design

PCB Assembly For Engineering Design assembles a variety of electronic devices onto a circuit board through a surface mount process. Next is the box assembly, which assembles the assembled PCB with the outer casing to form the finished product. That is to say, the PCB empty board passes through the SMT upper part, and then passes through the entire process of the DIP plug-in, referred to as PCBA.

PCB Features:

1. For PCB Assembly For Engineering Design, special or general-purpose circuit board, the bottom circuit is completed, and IO is reserved. After buying the industrial control circuit board, the input and output ports reserved on the circuit board are connected to the user's own device, such as motor. , solenoid valves, sensors to complete the functions they want to complete.

2. The special circuit board is a board specially designed for a certain function, such as the temperature control circuit board. After buying it, the input port is connected to the thermocouple, and the output port is connected with a heating contactor or a solid state relay to control the heating device to complete the temperature control. There are flow control boards, motion control boards, etc.

3, The general control board, most can be programmed, after the user's own secondary development, to complete a specific function, the use is more extensive, such as plc is a general industrial control board, after the user writes the program compile input, can complete various functions, there are Digital input, analog input port, high-speed counter port, digital output port, analog output port, and some also have communication function.
