What is pick and place machine?
Pick and place machine is the key and complex equipment in SMT production, which is used to attach components with high speed and high precision. Now the pick and place machine has developed from early low speed mechanical SMT machine to high speed optical centering SMT machine, and to multi-function, flexible connection modular development. In SMT production lines, it is equipped with a dispensing machine or solder paste printer to accurately place the surface mount components on the PCB pad by moving the mount head. Colloquially, it is a machine for attaching pin chip electronic components to a circuit board.
Pick and place machine working principle
The automatic pick and place machine is controlled by computer and is a high precision automatic equipment integrating optics, electricity and gas. It is mainly composed of rack, PCB transmission and load bearing organization, drive system, positioning and centering system, mounting head, feeder, optical identification system, sensor and computer control system. Through absorbing, displacement, positioning and placement functions, SMD components can be mounted quickly.
Can a pick and place machine solder?
Pick and place machine can’t weld.
NeDen provides professional hot air reflow oven. It transmits heat energy through the laminar movement of hot air. The heater and fan are used to make the air in the furnace constantly rise and circulate. The welds are heated by hot gas in the furnace, so as to realize welding. The hot air reflow oven furnace has the characteristics of uniform heating and stable temperature. It is not easy to control the temperature difference between the upper and lower PCB and the temperature gradient along the furnace length, so it is generally not used alone. Since the 1990 s, with the expansion of the SMT application and further miniaturization of components, equipment development manufacturers to improve the distribution of the heater, the circulation of the air flow, and temperature range of increase to 8, 10, to further precise control of furnace temperature distribution of each part is easier to ideal regulation of temperature curve. The full hot air forced convection reflow welding furnace has become the mainstream SMT welding equipment after continuous improvement and perfection.
