Our everyday lives are significantly impacted by electronics. Everything from our smart phones to our autos has electronic components. The printed circuit board, or PCB, is what powers these devices.

When they see printed circuit boards, most individuals can identify them. These are the tiny green chips with lines and copper components that are located at the core of disassembled electronic equipment. These boards are held together with epoxy and insulated with a solder mask. They are constructed from fiberglass, copper wires, and other metal components. That distinctive green hue originates from this solder mask.

The foundation, which is made up of multiple layers and is the most fundamental component of the PCB, is where the PCBA process always begins. Each layer is crucial to the finished PCB's functionality. Among these alternate layers are: The PCB's substrate is its foundational substance. The PCB gets its stiffness from it.

PCBA manufacturing generates a variety of pollutants, and it must be cleaned up afterward. The technique and flux used differ for products of different grades. There are differences in the cleaning technique, cleaning equipment, and cleaning substance needed. Currently, there are three main categories into which the cleaning process can be separated: fully automatic online cleaning machines, semi-automated offline cleaning machines, and manual cleaning machines.

Fully automated on-line cleaning machine
The fully automated on-line cleaning machine is mainly used to clean the residual surface of PCBA welding rosin flux, water soluble flux free flux, solder paste and other organic and inorganic pollutants thoroughly and effectively cleaning. It is suitable for large batch PCBA cleaning.

Semi automatic off-line cleaning machine
The main function of the semi automatic off-line cleaning machine is similar to the fully automated on-line cleaning machine, but it is small in size and can be placed at any place at will.

Manual cleaning machine
The manual cleaning machine is also called the constant temperature cleaning tank, which is suitable for the small batch sample PCBA order cleaning. Through the temperature control, the chemical cleaning is completed in a thermostat tank.
