SMT patch popular and the most important equipment


Reasons for the popularity of SMT patches in the electronics industry

SMT industry introduction

SMT: Abbreviation of English Surface Mount Technology, Chinese means surface mount welding (mounting) technology, the technology of soldering electronic parts to the surface of the circuit board. As a new generation of electronic assembly technology, SMT products have the advantages of compact structure, small size, vibration resistance, and high production efficiency. SMT has occupied a leading position in the circuit board assembly process. The main equipment of the SMT assembly line: printing Machine, placement machine, reflow soldering, etc.

Why is smt patch processing technology so popular? Advantages of SMT chip processing:

1. Electronic products are small in size and high in assembly density

The volume of SMT chip components is only about 10% of traditional package components, and the weight is only 10% of traditional plug-in components.

2. High reliability and strong anti-vibration ability

SMT chip processing uses chip components, which have high reliability, small size, light weight, strong anti-vibration ability, automatic production, high installation reliability, and low solder joint defect rate.

3. Good high frequency characteristics and reliable performance

Because the chip components are firmly mounted, the devices are usually leadless or short leads, which reduces the influence of parasitic inductance and parasitic capacitance, improves the high-frequency characteristics of the circuit, and reduces electromagnetic and radio frequency interference.

4. Improve productivity and realize automated production

The automatic placement machine (Yamaha automatic placement machine ysm-10/ysm-20) uses a vacuum nozzle to suck and release the components. The vacuum nozzle is smaller than the shape of the component, which improves the installation density.

5. Reduce costs and reduce expenses

SMT patch processing technology can save materials, energy, equipment, manpower, time, etc., and the cost can be reduced by up to 30% and 50%!

It is precisely because of the complexity of the process flow of SMT chip processing that there are many SMT chip processing factories that specialize in SMT chip processing.

The most important equipment in SMT patch processing

The core equipment in SMT placement processing is the SMT placement machine. The automatic placement machine is used to achieve high-speed, high-precision and automatic placement of components. It is the most critical and complex in the entire SMT production. equipment. The placement machine is the main equipment in the SMT production line. The placement machine has developed from an early low-speed mechanical placement machine to a high-speed optical centering placement machine, and has developed to a multi-functional, flexible connection and modularization.

Mounter as a high-tech product, safe and correct operation is very important to the machine and to people. The most basic thing to safely operate the placement machine is that the operator should have the most accurate judgment and follow the following basic safety rules.

The operator of the machine should receive the operation training under the correct method; When checking the machine, replacing parts or repairing and internal adjustment, the power should be turned off (the machine must be checked and repaired when the emergency button is pressed or the power is turned off; make sure to read When adjusting the machine, the YPU (programming component) is in your hands to stop the machine at any time; make sure that the “interlocking” safety equipment is kept effective to stop the machine at any time, and the safety inspection on the machine cannot be skipped or short-circuited. Otherwise, personal or machine safety accidents are prone to occur;

During production, only one operator is allowed to operate one machine; during operation, make sure that all parts of the body, such as hands and head, are outside the moving range of the machine; Use the machine in a flammable gas or extremely dirty environment.

In addition, it should be noted that SMT chip processing plants are strictly prohibited from operating on the machine without training; safety, machine operators should operate the machine strictly in accordance with the operating specifications, otherwise it may cause damage to the machine or endanger personal safety; machine operators should be careful.
