Single layer board is the most basic pcb type board, also called single panel, because the wire only appears on one side, so we call this pcb board single panel.
Double-sided PCB proofing, the most commonly used process. At the same time rosin process, OSP process, gold plating process, gold plating, silver plating these processes, in the double panel is also applicable.
Single-Sided pcb Smt
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.
