SMT is a surface mount technology (surface mount technology) (abbreviation of Surface Mounted Technology) and is currently the most popular technology and process in the electronic assembly industry. SMT patch refers to the abbreviation of the series of process flow based on the PCB. How is the part mounted on the PCB? What is the SMT production process? Zhichi Technology here to introduce everyone on the SMT equipment, SMT process technology and peripheral items awareness and precautions.

Equipment to be used on SMT production line

There are seven kinds of commonly used equipment: Loader, Stacker, Solder printer, Highspeed mounter, Coveryor general purpose placement machine (Multi (function mounter), Reflow, Unloader, AOI, X-RAY. In addition, air compressors must be supplied to the machine for normal production. .

SMT production line equipment role

1, the board machine: PCB placed in Rack automatically sent to the suction plate machine.

2, the suction dryer plate: automatic sucking PCB placed over the track, is transmitted to the printer.

3, the printer: a laser light on the solder paste on the steel or steel complete printed red plastic PCB.

4, high-speed placement machine: the use of equipment editing procedures will be placed on the components of the specified parts, can be loaded with SOP 28pin the following roll-like parts, which is characterized by fast loading.

5, docking station: means for transmitting the PCB.

6. General-purpose mounter: Use the device edit program to place the component on the specified part position, and mount SOP more than 28pin (including components that can be mounted on the high-speed machine) Roller, disc or tube packaging components . It is characterized by high precision and diversification, but it is inferior to high-speed machines.

7, reflow: the SMT solder paste or red glue using the temperature set an appropriate temperature curve so that solder paste and parts to complete the welding action.

8, Unloader (Unloader): Through the transmission track, closed in magzine.

9, optical detector: automatic optical detection, is based on the optical principle to detect common defects encountered in welding production equipment. AOI is a new type of test technology that has only emerged in recent years, but it has developed rapidly. At present, many manufacturers have introduced AOI test equipment. When automatically detected, the machine automatically scans the PCB through the camera, collects the images, and compares the tested solder joints with the qualified parameters in the database. After image processing, the defects on the PCB are detected, and the defects are displayed/marked through the display or the automatic mark. Come out for maintenance personnel to trim.

10, X-ray machine: mainly used to detect various types of industrial components, electronic components, circuits inside. For example, socket plug rubber internal wiring connection, diode internal welding, BGA welding and other tests. The X-ray machine is an X-ray machine that can be connected to computers for image processing. Such industrial inspection portable X-ray machines provide excellent solutions for the field of factory appliance maintenance.

Radar Level Gauge Sensor

It is used for continuous level measurement. The signal transmitted by its sensor is collected by the receiving system after being reflected by the target, and the distance of the target is determined by measuring the reflection running time. Then the level distance is converted into an output signal and output as a measured value.

The liquid level radar is applicable to the continuous non-contact liquid level measurement of liquid cargo tanks and overflow tanks of oil tankers and chemical carriers. It is also applicable to the liquid level monitoring of other oil tanks, towers, tank equipment and oil production platforms. Its measurement results are not affected by medium replacement, temperature change and gas or steam coverage.
