The selection and management of SMT accessories, one of the most popular technologies and processes in the electronics assembly industry, is a crucial part of electronics manufacturing. Proper selection and management of SMT accessories can save extra time and cost during production. In this article, we will discuss the selection and management of SMT accessories in detail.

First, the main categories and characteristics of SMT accessories

1. stencil: used in the SMD process, used to print solder paste, SMT stencil selection needs to be based on the thickness of the SMT patch route and the type and number of parts to select different apertures and aperture area.

2. Solder Paste: It is the main material used in the SMT mounting process to stick the parts on the PCB. The selection of solder paste needs to consider the viscosity of the paste, the composition of the paste, the temperature of the paste and other factors.

3. SMD machine: is the main equipment used in the SMT placement process, used to paste the parts on the PCB. The selection of the mounter needs to consider the mounter speed, precision, stability and other factors.

4. reflow oven: is the main equipment used in the SMT placement process, used to weld the parts on the PCB. Reflow oven selection needs to consider the reflow oven temperature, speed, stability and other factors.

Second, the choice of SMT accessories

1. Stencil selection: according to the thickness of the SMT patch route and the type and number of parts to select different apertures and aperture area.

2. the choice of solder paste: according to the viscosity of the paste, the composition of the paste, paste temperature and other factors to choose.

3. Selection of mounter: according to the mounter's speed, precision, stability and other factors to choose.

4. Reflow oven selection: according to the reflow oven temperature, speed, stability and other factors to choose.

Third, the management of SMT accessories

1. Stencil management: the service life of the stencil is generally 300-500 times, need to be replaced on a regular basis. Stencil storage need to pay attention to dust, moisture, sun and other factors.

2. solder paste management: the service life of the solder paste is generally 24 hours, need to be replaced regularly. The storage of solder paste needs to pay attention to moisture-proof, sun-proof, dust-proof and other factors.

3. management of the chip machine: the service life of the chip machine is generally 5-10 years, need regular maintenance and maintenance. The storage of the SMD machine needs to pay attention to dust, moisture, sun and other factors.

4. reflow soldering furnace management: reflow soldering furnace service life is generally 5-10 years, requiring regular maintenance and repair. Reflow oven storage need to pay attention to dust, moisture, sun and other factors.

In summary, the selection and management of SMT accessories is a crucial part of electronic manufacturing. Reasonable selection and management of SMT accessories can save extra time and cost during production. In the era of rapid technological development, electronic product manufacturing is very important, the circuit control board is the core component, the SMT production line needs automatic board loading and unloading machine, docking station, semi-automatic solder paste printer and other peripheral ancillary equipment, in order to achieve rapid and efficient production. Therefore, the selection and management of SMT accessories need to take into account a variety of factors to ensure the smooth running of production.
