The difference between DIP and SMD package of LED display
2020-05-25 10:46
    In the production process, packaging is very important. Today, there are two common packaging methods on the market: DIP and SMD packaging. What is the difference between these two packages, and what are the advantages and disadvantages, Shenzhen LED display manufacturer Shenzhen Forbes will answer your questions next:
    What is the role of LED display packaging?
    The outer lead is connected to the electrode of the LED display chip, and at the same time, the LED display chip is well protected, which improves the luminous efficiency and the heat dissipation environment, and thus improves the life of the LED.
    LED display in-line DIP and package SMD comparison effect chart:

  
   1. DIP package
 
    DIP package is an abbreviation of dual inline-pin package, commonly known as plug-in type. It was first developed. The LED lamp beads are produced by the manufacturer, and then inserted by the LED module and LED display manufacturer into the LED PCB lamp board, and the DIP semi-outdoor module and outdoor waterproof module are produced by wave soldering.
 
    However, due to the influence of the diameter of the lamp beads, currently only P6 can be achieved. Other P5, P4 and even higher-density outdoor LED displays cannot be made. But the in-line protection is good, but the viewing angle is not accurate and fixed, generally between 100-110, and high energy consumption, not environmentally friendly, so it is only suitable for outdoor, currently there is a larger market for outdoor P10-P20 Share.
 
    Moreover, it is produced by DIP packaging, the process is complicated, it is not easy to mechanize production, and the production efficiency is low. In addition, there are many DIP manufacturers, there is no high technology and equipment threshold, and competition is fierce. Many manufacturers use inferior raw materials and PCB boards to reduce costs to gain market share. The quality is low and there is almost no perfect after-sales guarantee.
 
    2. SMD encapsulation
 
    SMD package means: surface mount device, which is one of SMT components. Surface-mount components were introduced about twenty years ago, and a new era was created. For a long time, it was thought that all lead components could eventually be packaged in SMD. SMD technology is widely used in LED outdoor display.
 
    We often say that the three-in-one sticker is actually a kind of SMD technology. It refers to the SMT lamp that encapsulates three different colors of RGB LED chips in a same gel at a certain interval.
 
    The advantages of the three-in-one outdoor full-color LED display with stickers are as follows: the viewing angle of the entire screen is relatively larger than that of the in-line screen, and the surface can be diffused and reflected. . The three-in-one overall flatness is easier to control, and has always been the standard technology used in high-definition outdoor LED displays.
 
    With the development of technology and continuous improvement of production technology in recent years, SMD has developed rapidly and the cost has been reduced a lot. It is currently the mainstream product for LED indoor displays. Moreover, it has developed rapidly to the outdoor market, but its brightness, water and moisture resistance have always been difficult to overcome. I believe that the entire industry is constantly developing, and development is the direction of surface stickers.
