Closer to home, what processes does the SMT production line include? We must first understand the SMT assembly line process so we could find a good manufacturer. The following is the general process of the SMT production line. soldering method and dispensing process are all different depending on the wiring method.
The solder paste or patch glue is printed on the smt stencil to prepare for the soldering of the components. All equipment is a solder paste printer located at the front of the SMT production line .
The glue dispenser is used to drop glue onto the fixed position of the SMT stencil. Its main function is to fix surface-mounted components on the PCB when wave soldering is used. The glue dispenser is found in front of the SMT production line or behind the testing SMT assembly equipment.
A placement machine is often used to mount the surface-mounted components on a fixed position of the SMT stencil. It is located behind the solder paste printer in the SMT production line.
A curing oven is used to cure the SMD glue so that the surface assembly components and SMT stencil are firmly bonded together. It is located behind the placement machine in the SMT production line.
Melt the solder paste to firmly bond the surface-mounted components and SMT stencil. The equipment used is a reflow oven. Located behind the placement machine in the SMT production line.
Remove the solder residues, such as flux, harmful to the human body or the product on the assembled PCB. The equipment used is a cleaning agent, and the unknown may not be fixed. It may be online or offline. When using no-clean welding technology, this process is not provided.
We use a variety of tools to inspect the welding and assembly quality of the surface mount component. The equipment includes a magnifying glass, microscope, online tester, first article tester, and more... The specific equipment used will depend on the specific testing needs. These tools can be placed in a suitable location on the SMT production line.
Repair the SMA that is faulty. The tools used are electric soldering irons, rework workstations, etc. Configured anywhere in the smt line .
