SMT electronic patch

SMT patch introduction

Update time: 2018-05-30
SMT patch refers to the abbreviation of the series of process flow based on the PCB. The printed circuit board (PCB) is a printed circuit board.
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. Surface Mount Technology (SMT) is called surface mount or surface mount technology. It is a kind of short leads or leadless surface mount components (referred to as SMC / SMD, Chinese called chip components) mounted on a printed circuit board on the other surface of the surface or substrate (Printed Circuit Board, PCB) by Reflow soldering or dip soldering and other methods of solder assembly circuit assembly technology.
Under normal circumstances, we use electronic products are pcb plus a variety of capacitors, resistors and otherelectronic components designed according to the design of the circuit diagram, so all kinds of electrical appliances require a variety of different smt chip processing technology to process.
The basic components of the process SMT: Printing Paste -> Parts Mount -> Reflow contact -> the AOI optical detection -> Maintenance -> scoreboard.

Some people may ask why it is so complicated to pick up an electronic component. This is actually closely related to the development of our electronics industry. Today, electronic products are pursuing miniaturization, and previously used perforated plug-in components. Can't zoom out. Electronic products have more complete functions, and the integrated circuits (IC) used have no perforated components, especially large-scale, high-integration ICs, and surface patches have to be used. With product batching and production automation, the factory must produce high-quality products to meet the needs of customers and strengthen the development of market-competitive electronic components, integrated circuit (IC) development, and multiple applications of semiconductor materials at low cost and high output. The electronic technology revolution is imperative and pursues international trends. It can be imagined that in the case of intel, amd and other international cpu, the production process of the image processing device manufacturer is refined to 20 nanometers and nanometers, and the development of the smt surface assembly technology and process is also not allowed to be the case.

Smt chip processing advantages: high assembly density, electronic products, small size, light weight, patch components, the size and weight of only about 1/10 of the traditional cartridge components, the general use of SMT, the electronic product volume reduction 40% ~ 60 %, weight loss 60%~80%. High reliability and strong vibration resistance.The solder joint defect rate is low. High frequency characteristics. Reduced electromagnetic and radio frequency interference. Easy to automate and increase productivity. Reduce costs by 30% to 50%. Save on materials, energy, equipment, manpower, and time.

It is due to the complexity of the smt chip processing process, so there are a lot of smt chip processing factory, professional smt patch processing, in Shenzhen, thanks to the vigorous development of the electronics industry, smt chip processing achievements The prosperity of an industry.
