Special attention should be paid to the production of double-sided circuit boards for metal-based pcb boards

Today author from QiHe smt pick and place machine tell you about it with you the special attention should be paid to the production of double-sided circuit boards for metal-based pcb boards

With the continuous development of electronic products, the variety and frequency of various equipment failures have also greatly increased.
Therefore, the requirements for operators are constantly increasing.
Especially for someone new to circuit board repair,
Many people don’t know where to start at first.
In fact, if you want to learn to professionally produce and sell double-sided circuit boards, you must have a certain foundation in digital and analog electronics.

Therefore, repairs should pay attention to the following items:

  1. Pay attention to the safety of electricity use, including the maximum bearing capacity of the circuit board when professionally producing and selling double-sided circuit boards;
    When you need to touch strong electricity, you must pay attention to personal safety and take measures to prevent strong electricity.
  1. Before professionally producing and selling double-sided circuit boards, anti-static work must be done first.
    For example, wear anti-static work clothes and shoes, and wear an anti-static wrist strap.
    The repaired workbench should also be treated with anti-static treatment, such as adding an anti-static table.

WHAT IS SMT ASSEMBLY LINE?

With the development of technology, future electronic products will be lighter, smaller and thinner. Traditional assembly technology can no longer meet the requirements of high-precision and high-density assembly. A new type of PCB assembly technology-SMT (Surface Mount Technology) has emerged. SMT Assembly is the use of automated machines to assemble electronic components on the surface of the circuit board. Its density, high speed, standardization and other characteristics occupies an absolute advantage in the field of circuit assembly technology. In addition, SMT assembly has a wide range of uses.

WHAT IS SMT pick and place machine?

SMT (Surface Mounted Technology) is a comprehensive system engineering technology, which covers substrates, design, equipment, components, assembly processes, production accessories and management. When it comes to SMT pick and place machines, the automatic SMT production line requires automatic loading and unloading machine, automatic solder paste printing machine, placement machine, reflow soldering machine, AOI inspection equipment, connecting table, etc. For these SMT assembly line equipment, Qihe SMT can offer you machines in prototype SMT line, small SMT production line, mass production SMT line at low SMT line cost. Contact us now if you are interested.

WHAT IS SMT PROCESS?

There are mainly three steps in SMT assembly line process flow: solder paste printing, components placement and reflow soldering.

  1. Solder Paste Printing
    Its function in SMT line process is to print the solder-free paste on the pads of the PCB to prepare for the soldering of the components. The equipment used is a screen printing machine, located at the forefront of the SMT production line.
  2. Components Placement
    Its function is to accurately install the surface mount components on the fixed position of the PCB. The equipment used is a placement machine, located behind the screen printing machine in the SMT production line.
  3. Reflow Soldering
    Its function in SMT manufacturing line is to melt the solder paste so that the surface mount components and the PCB board are firmly bonded together. The equipment used is a reflow oven, located behind the placement machine in the fully automatic SMT production line.
