PCBA Tech - Application analysis of SMT patch in the electronics industry

This article is mainly about the analysis of the reasons why SMT chip processing is widely used in the electronics industry

Patch processing is also called SMT patch processing or surface mount technology. Almost 90% of electronic products now use SMT chip processing technology, so why can chip processing be widely used in the electronics industry?

1. SMT chip processing reduces the volume of electronic products. In life, we can all feel that the size of current electronic products is getting smaller and smaller, from the big brothers used in the past to the small smart phones used now, from the bulky desktop computers used in the past to the super notebook. This is mainly due to the use of SMT chip processing technology to reduce the volume of electronic products by 60%, which greatly improves the assembly density of computer motherboards or mobile phone chips, thereby improving the performance of electronic products, and the volume is also Can be reduced, in line with people's current habits.

2. SMT chip processing makes electronic products easy to automate production. In order to realize the automated production of electronic products, it is necessary to consider whether the area of the PCB board has enough space for the insertion head of the automatic plug-in to insert the components, so as to realize the automated production. The first major advantage of SMT processing is the high assembly density, while also reducing the size of the PCB circuit board, making it possible to achieve full-line automated production.

3. The electronic components processed by SMT patches are firmly mounted. The devices are usually leadless or short leads, which reduces the influence of parasitic inductance and parasitic capacitance, and improves the high-frequency characteristics of the circuit.

4. SMT chip processing makes the electronic components have strong shock resistance and high reliability. According to statistics, in the process of patch processing, the rate of bad solder joints is generally less than 10 parts per million, which is an order of magnitude lower than the wave soldering technology of PCB through-hole plug-in components. It also makes the electronic components have strong shock resistance. Oscillation causes the pins on the component board to fall off.

5. SMT chip processing reduces production costs. Production cost is a problem that every manufacturer must consider. Combining the four advantages mentioned above, the use of patch processing technology can reduce the area of the printed board and reduce the cost of materials, and due to the improvement of frequency characteristics, Reducing the cost of circuit debugging, and at the same time SMT automated production also improves the production efficiency, to a certain extent also saves a lot of costs. In addition, because the processed electronic components are small in size and light in weight, packaging, transportation and storage costs are reduced.

The above is an analysis of the reasons why SMT chip processing is widely used in the electronics industry
