The SMT production process is a circuit assembly technology in which lead-free short-lead surface-mounted components are mounted on the surface of a printed circuit board on the surface of other substrates, soldered assembled by reflow soldering dip soldering. The main production equipment is the SMT placement machine. The SMT placement machine is a machine that accurately places the SMD surface-mount devices on the corresponding pads on the PCB circuit board through a pick place process. Surface mount devices include capacitors, resistors, ICs other devices. These devices can be quickly accurately placed on circuit boards through SMT placement machines.

SMT placement machines are like high-tech products such as computers mobile phones that are often used today. Their internal motherboards are closely aligned with tiny capacitors resistors, which are affixed through a patch processing technique. Capacitors resistors processed by high-tech chip mounting are faster than manual chip mounting are prone to errors. Therefore, smt mounters have certain requirements for the working environment, in order to ensure the quality of electronic components, they have the following requirements for the working environment:


1. SMT placement machine requirements for working environment temperature: the annual temperature of the plant is 23 ± 3 ℃, which should exceed the limit temperature of 15 ℃ ~ 35 ℃.


2. SMT placement machine's humidity requirements for the working environment: The humidity of the placement processing workshop has a great impact on product quality. The greater the ambient humidity, the more susceptible the electronic components are to moisture. This will affect the electrical conductivity. At the same time, the welding is smooth the humidity is too low. When the workshop air is dry, static electricity will be generated. Therefore, when entering the SMT placement processing workshop, the processing staff also needs Wear antistatic clothing. Under normal circumstances, the workshop needs to maintain a constant humidity of 45% to 70% RH.


3. SMT mounter's power requirements for the working environment: The stability of the power supply is required. In order to avoid equipment failure during the placement process affect the quality progress of the processing, a regulator must be added to the power supply to ensure the power supply. The stability.


4. SMT mounter's requirements for the cleanliness of the working environment: The SMT mounter workshop guarantees that the workshop is free of odor dust, keeps the room clean free of corrosive substances, seriously affects the reliability of capacitor resistance, improves the failure repair rate of SMT equipment. To improve the reliability of the equipment reduce the production schedule. The cleanliness of the workshop is about BGJ73-84.
