Populated Printed Circuit Board Manufacturing PCB Fabrication
Assembly
what is populated printed circuit board ?
A populated printed circuit board (PCB) refers to a circuit board
that has electronic components such as resistors, capacitors,
integrated circuits, and other active or passive devices mounted
and soldered onto it. The process of adding these components to the
PCB is known as “populating” the board. Once the components are
added, the PCB is said to be “populated” and is ready for further
testing and integration into electronic devices.
Double-sided PCB board
Double-sided PCB board is a very important PCB board in the circuit
board, the market has double-sided circuit board metal base PCB
board, Hi-Tg heavy copper foil circuit board, flat winding
double-sided circuit board, high frequency PCB, mixed dielectric
base high frequency double-sided circuit board, etc. It is suitable
for a wide range of high-tech industries such as:
telecommunications, power supply, computer, industrial control,
digital products, scientific and educational instruments, medical
instruments, automobiles, aerospace defense and so on.

SMT basic process
SMT basic process elements include: screen printing (or
dispensing), mounting (curing), reflow soldering, cleaning,
testing, repair
1. Screen printing: Its function is to leak solder paste or patch
glue onto the PCB pad to prepare for the welding of components. The
equipment used is screen printing machine (screen printing
machine), located at the front end of the SMT line.
2, dispensing: it is to drop the glue to the fixed position of the
PCB board, its main role is to fix the components to the PCB board.
The equipment used is the dispensing machine, which is located at
the front end of the SMT production line or behind the testing
equipment.
3. Mounting: Its function is to accurately install the surface
assembly components to the fixed position of PCB. The equipment
used is the SMT machine, which is located behind the screen
printing machine in the SMT production line.
4, curing: its role is to melt the patch glue, so that the surface
assembly components and PCB board firmly bonded together. The
equipment used is the curing furnace, which is located behind the
SMT machine in the SMT line.
