Bright Idea! Stop importing from China and Invest in LED Assembly Equipment
MARKET DEMAND FOR LED MANUFACTURING
Today, LEDs are used for bulbs and tubes but increasingly they are being used in the many lighting components necessary for automobiles, airplanes, appliances, computers, electronics, televisions and more. LEDs use a whopping 80% less energy than old Incandescent Lighting and 50% less than Compact Fluorescent Lighting. Soon, international mandates to deal with climate change, like the Paris Agreement, will make an already huge market, topple over with growth and opportunity.
LEDs offer a promising solution to deal with energy agendas set forth by conventional international treaties and local environmental policies that seek to gain quantifiable reductions in fossil fuel usage. LEDs are a simple, yet integral solution to improving energy efficiency and helping to solve the issue of climate change. Are you keeping up with the Paris Agreement and what that means for a BOOMING LED Market?

Profesional in AI/SMT machine and spare parts of AI/SMT .
1.We have original drawing ,what we can make is almost the same quality with original spare parts.
2.All the process when manufactured ,our engineer would give guide and test the quality.
3.Only when the qulity is passed will we let the parts into our store.
4.Also we can control our spare parts in a very low price, when control it on a good quality.
Electronics manufacturing using surface-mount technology (SMT) simply means that electronic components are assembled with automated machines that place components on the surface of a board (printed circuit board, PCB).
Electronics manufacturing using surface-mount technology (SMT) simply means that electronic components are assembled with automated machines that place components on the surface of a board (printed circuit board, PCB). In contrast to conventional through-hole technology (THT) processes, SMT components are placed directly on the surface of a PCB instead of being soldered to a wire lead. When it comes to electronic assembly, SMT is the most frequently used process in the industry.
Electronic assembly encompasses not only placing and soldering components to the PCB, but also the following production steps:
- Applying soldering paste, which is made of tin particles and flux, to the PCB
- Placing SMT components to the soldering paste on the PCB
- Soldering the boards with a reflow process.
Applying Soldering Paste
Applying soldering paste is one of the first steps in the SMT assembly process. Soldering paste is “printed” on the boards using the silk-screen method. Depending on the design of the board, different stainless-steel stencils for “printing” the paste onto the board and various product-specific pastes are used. Using a laser cut stainless-steel stencil custom made for the project, the soldering paste to be applied only to the areas where components will be soldered. After the soldering paste is on the boards, a 2D-soldering paste inspection is performed to ensure that the paste is evenly and correctly applied. Once the accuracy of the soldering paste application has been confirmed, the boards are transferred to the SMT assembly line, where the components will be soldered.
Component Placement and Assembly
The electronic components to be assembled come in trays or reels, which are then loaded into the SMT machine. During the loading process, intelligent software systems ensure that components are not inadvertently switched or misloaded. The SMT assembly machine then automatically removes each component with a vacuum pipette from its tray or reel and places it on its correct position on the board using precise pre-programmed X-Y coordinates. Our machines are capable of assembling up to 25,000 components per hour. After the SMT assembly is completed, the boards are moved on to the Reflow ovens for soldering, which affixes the components to the board.
Component Soldering
To solder electronic components, we use two different methods, each of which has distinct advantages depending on the order quantity. For series production orders, the Reflow-soldering process is used. During this process, boards are put in a nitrogen atmosphere and are gradually warmed up with heated air until the soldering paste melts and the flux vaporizes, which fuses the components to the PCB. After this stage, the boards are cooled off. As the tin in the soldering paste hardens, the components become permanently affixed to the board and the SMT assembly process is completed.
For prototypes or highly sensitive components, we have a specialized vapor-phase soldering process. In this process, boards are heated until the specific melting point (Galden) of the soldering paste is reached. This allows us to solder at lower temperatures or solder different SMT components at different temperatures depending on their individual soldering temperature profiles.
AOI and Visual Check
Soldering is the second-to-last step of the SMT assembly process. In order to ensure the quality of the assembled boards, or to catch and correct a mistake, AOI visual inspections are performed for almost all series production orders. Using several cameras, the AOI system automatically checks each board and compares the appearance of each board with the correct, pre-defined reference image. If there are any deviations, the operator of the machine is informed of the potential problem, who then corrects the mistake or pulls the board from the machine for further inspection. The AOI visual check ensures consistency and accuracy in the SMT assembly production process.
Automation technique is applied to the development of mechanical manufacturing industry ，which can greatly improve productivity, in other hands, the machinery manufacturing automation technology is currently one of the most valuable in the world of science and technology, it is to promote the development of social productivity and also make people’s life become more quickly, play an important role in improving people’s living standard.
But with the development of mechanical processing manufacturing, also can not avoid artificial operating machinery and equipment, and always heard the sad news, such as workers injury or death when operating the machine.On May 29, a factory ‘s worker body is stuck to the machine unfortunately when operating the machine， while firefighters rushed to the rescue, the women were taken to a hospital successful, but the last，the woman died of his wounds.This let us deep thinking.
So in our SMT/AI industry，every workers must to know the machine security issues and safety guidelines，it‘s very important，we must ensure the safety of workers！
Security issues and safety guidelines：
1 Tooling cuff requirements beam, work shoes should be prevented slippery, and can’t wear high heels.
2 When working alongside the material stack， must press the STOP button bright women scarves.
3 The woman should on long hair to disk, and the men tie to close firmly, prevent into the machine at work.
4 Single machine operation, it is strictly prohibited to many people at the same time.
5 Hands in upper and lower, inside the machine components to use pliers or tweezers (axial element), hands, hands after leaving the plug-in area, then operate the control panel.
6 Must sure to remove all tools sundry machine worktable when start to operate the machine.
7 Work in it is prohibited to put any goods on the worktable, so as not to damage the machine.
8 In the work such as unexplained machine stopped suddenly, may not be reached below the plug-in head.
9 Plug-in mistakes in normal production, may not be reached to the head.
10 For the automatic machine, the machine in normal production, it is forbidden to reach into to send slab bridge.
11 To understand the mesa machine movement area, not collision.
Maybe there are more things we should care，safety is the basis of the production.So please every factory ’s leader pay more attention to the Security issues and the workers must be more care.
