  • The main recommendation for disassembly of high pin density components in SMT patch processing is to use a hot air gun to clamp the components with tweezers, blow all the pins back and forth with the hot air gun, and lift the components when they are melted. If you need to disassemble the parts, do not blow to the center of the parts, and the time should be as short as possible. And clean the gasket with a soldering iron after removing the parts. For SMT cleaner machine components with a small number of pins, such as resistors, capacitors, bipolars and triodes, first tin plating on a pad on the PCB board, and then use tweezers to clamp the component in the mounting position with your left hand and fix it on the circuit On the board, use the right hand to solder the pins on the pads to the pads sold. The tweezers in the left hand can be loosened, and the remaining feet can be soldered with tin wires. This kind of part is also easy to disassemble, as long as both ends of the part and the soldering iron are heated at the same time, and the tin is melted and lifted slightly to disassemble.

  • Welding technology plays an extremely important role in the assembly of electronic products. General welding is divided into two categories: one is mainly applied to the welding of through-hole plug-type electronic components and printed boards - wave soldering, the so-called wave soldering (wavesoldering) is to melt the solder, the electric The pump or electromagnetic pump sprays the solder wave peaks required by the design to allow the printed boards pre-equipped with electronic components to pass through the solder peaks to achieve the mechanical and electrical connection between the component terminals or the leads and the PCB pads. Brazing; the other is mainly used for surface-mount components and printed board reflow soldering (reflowsoldering), also known as reflow soldering, the so-called reflow is re-melted by pre-distribution to the PCB pad The paste solder on the solder paste realizes the soldering of the surface-mount components or the mechanical and electrical connection between the leads and the printed circuit board pad, thereby realizing the circuit function with certain reliability. With the large-scale use of surface mount components in electronic products, reflow soldering technology has become a major process technology in surface mount technology. Its main process features are: the surface of the metal to be welded is cleaned (removed oxide) with a flux to make it have good wettability to the solder; the molten solder is supplied to moisten the metal surface; and the intermetallic compound is formed between the solder and the weld metal In addition, micro-welding can be realized. Reflow soldering is a group or point-by-point soldering process in which a proper amount and appropriate form of solder are applied to the soldered area (pad) of the PCB in advance, and then the surface mounted components are placed and the solder is reflowed by the external heat source to meet the soldering requirements. Reflow soldering has the followin

  • The harm of static electricity to PCBA products When processing PCBA, processing personnel will strictly follow the bill of materials, PCB silk screen and outsourcing processing requirements to insert or mount components. However, electronic components often generate more or less static electricity without paying attention. These static electricity will emit electromagnetic pulses during discharge, which will cause errors in computer calculations. In severe cases, they will also cause damage to devices and circuits. Only by taking anti-static measures can the machine and components be protected. How should anti-static measures be taken during PCBA processing? Anti-static measures for PCBA processing 1. All personnel who come into contact with components and products wear anti-static clothes, anti-static bracelets, and anti-static shoes. 2. The anti-static system must have a reliable grounding device. The anti-static ground wire must not be connected to the power neutral wire or shared with the lightning protection ground wire. 3. All components are treated as electrostatic sensitive devices. 4. During the operation, use an anti-static work surface, and use anti-static containers for components and semi-finished products. 5. The welding equipment is grounded reliably, and the electric soldering iron is of anti-static type, which must be tested before use. 6. Warehouse management personnel should wear anti-static gloves when sending materials and IQC inspections, use meters to be grounded reliably, and anti-static rubber pads on the work surface. 7. Periodically inspect the above-mentioned anti-static tools, settings and materials to confirm that they are in the
