SMT stands for Surface Mount Technology, and it refers to the procedure of mounting electronic components line transistors, resistors, integrated circuits, and capacitors onto the surface of PCB in electronics.

It was 1st invented in 1960 by a giant name in the computer field IBM and then widely implemented in high-tech electric PCB assemblies. The electric component mounted during the SMT assembly procedure is the so-called SMD (Surface Mount Device).

Types of SMT Lines

There’re several forms of Surface Mount Technology lines, each made for specific production purposes and production needs. One common distinction is based on production rate, with lines listed as low-volume, mid-volume, and high-volume Surface Mount Technology lines.

· Low-volume lines are ideal for small-scale production, providing flexibility and cost-efficiency.

· Medium-volume level lines are used for moderate production needs.

· High-volume lines are highly optimized for bigger scale and continuous production.

Furthermore, SMT lines can be categorized based on automation level, with semi-automatic, manual, or entirely automatic lines also available to put up varying production requirements and budgets.

Moreover, specialized SMT lines exist for individual apps, such as consumer electronics, automotive electronics, and industrial equipment. These lines are designed to meet the specific needs and standards of their respective fields to ensure precise and efficient assembly of electric components on PCBs.

What equipments are needed to start SMT Production line?

To start the SMT line, several essential pieces of equipment are needed to facilitate the precise assembly process of electronic components onto PCBs. These include –

  1. Solder Paste Printer– This is used to perfectly apply solder paste onto the printed circuit board to ensure sure right adhesion of the components.
  2. Pick and Place MachineThe job of this equipment is to pick up electric components and place them onto the PCB with speed and high precision.
  3. Reflow OvenIt’s used to melt the soldering paste, creating a permanent link between PCB and components.
  4. Stencil PrinterThis device is used to make soldering paste stencils, which is required for rightly applying soldering paste onto the PCB.
  5. Inspection EquipmentSeveral inspection equipment such as Automated Optical Inspection & X-ray machine are utilized to ensure the quality and perfection of solder joints and component placement.
  6. Conveyor SystemIt’s employed to transport PCBs via different stages of the assembly procedure to ensure a smooth and continuous workflow.
  7. Handling and Components Storage Equipment –It includes trays, components feeders as well as reels to store and supply electric components to the pick & place machine.
  8. Cleaning equipment –These are used to eliminate any residues or contaminants from the assembled PCBs.
  9. Testing & quality control equipment –It includes functional testing and tools for inspecting soldering joints and whole PCB quality.
  10. Environmental control system –This equipment helps maintain the right temperature and moisture level within the production environment to ensure the quality of the assembly procedure.

These important pieces of equipment are from the base infrastructure of an SMT line, allowing the precise and effective assembly of electronic components onto PCBs. Furthermore, considerations for Electrostatic Discharge (ESD) protection, workspace layout, and safety devices are also important for building a safe and productive SMT line production environment.

Tips to Choose the Right Equipment

Based on the search outcomes, the equipment to pick for starting the SMT production line should align with the individual production needs as well as budget considerations. Here’re some important considerations for choosing equipment.

  • Pick a soldering paste printer that provides consistent and precise applications of solder paste on the PCBs, considering all the factors such as perfection, speed of printing, and compatibility with the SMT production line.
  • Choose a pick-and-place device that can easily handle the needed component sizes and types, providing high speed and the right placement onto PCBs. Consider the flexibility, ease of programming, and feeder capacity of the machine.
  • Pick a reflow oven that offers uniform and managed solder reflow and makes sure of reliable and proper solder joints. Consider energy efficiency, temperature profiling functions, and the heating zone of the ovens.
  • Choose inspection tools such as X-ray machines and Automated Optical inspection that can easily identify issues and ensure the accuracy and quality of placement and soldering joints.
  • Pick a conveyor system that is ideal for production volume and layout, offering smooth and accurate transportation of PCBs via several stages of the procedure.
  • Choose a component storage manager such as trays, feeders, and reels that can easily store and supply components to the pick and place device, considering all these factors such as organization and capacity.
  • Consider tools for functional testing and inspecting soldering joints to ensure the performance and reliability of assembled PCBs.
    Pick a system that maintains the right temperature and moisture level in a production environment, and ensure the quality assembly procedure.

When choosing equipment for an SMT production line, it is vital to consider factors such as equipment performance, compatibility with future expansion, after-sales support, and loyalty to industry regulations and standards. Further, evaluating the full cost, including operational and maintenance costs is vital for making the right equipment choices.

Budget for Starting an SMT Line

The budget needed to start an SMT line can depend on various factors such as the scale of production, automation of level, and specific equipment needs. Although, based on available info, it’s possible to establish a starting budget guideline.

According to a discussion on setting up a low-medium volume SMT line, the budget target was set at between $50,000 to $130,000, indicating that the budget can be the right starting mark for a small to mid-level SMT line.

It is vital to note that this budget plan can be flexible and might need to be adjusted based on the specific needs of the production line, the price of equipment, facility setup, and some other expenses.

The major cost components of setting up the production line of SMT include the purchase of equipment such as soldering paste printers, Reflow ovens, pick and place machines, conveyor systems, inspection tools, and handling and component storage equipment.
