The Function of Solder Paste
Solder paste is a new type of welding material accompanied by SMT. It is a paste mixture formed by mixing solder powder, flux and other surfactants and thixotropic agents. Mainly used in SMT industry PCB surface resistance, capacitance, IC and other electronic components welding.
In the 1970s, Surface Mount Technology refers to printing and coating solder paste on the solder paste pad of printed circuit board, and accurately sticking the surface mount components on the solder paste pad, heating the circuit board according to a specific reflux temperature curve, so that the solder paste can melt. The alloy component is cooled and solidified to form solder joints between components and printed circuit boards to realize metallurgical connection technology.
Solder paste is a new kind of welding material accompanied by SMT. Solder paste is a complex system, is made of solder powder, flux and other additives mixed paste. The solder paste has a certain viscosity at room temperature, which can initially stick the electronic components in the established position. At the welding temperature, with the volatilization of solvent and some additives, the welded components and printed circuit pad will be welded together to form a permanent connection.
Working mode
Using scraper, stencil, PCB is fixed by vacuum suction. The optical positioning points (MARK points) of the substrate and the stencil on the worktable are aligned by the camera of the printer, and then the substrate and the stencil are finely adjusted so that the pattern of the substrate pad and the opening pattern of the stencil are completely coincident
The Function of scraper
In SMT solder paste printing PCB board, one of the processes is to use a scraper to squeeze solder paste, so as to transfer solder paste from the steel screen to the PCB board. The scraper system is the most complex motion mechanism on the printing press, including the scraper fixing mechanism, the transmission control system of the scraper, etc.
The function of the scraper system is to make the solder paste expand into a uniform layer on the whole template area. The scraper presses the template to make the template contact with PCB. The scraper pushes the solder paste on the stencil forward while filling the stencil opening; When the template is removed from the PCB, leave a solder paste of appropriate thickness on the PCB corresponding to the template figure

Service
Our service can be divided into three parts: pre-sales service, in-sales service and after-sales service:
1)Pre-sales service can be called professional product consultation. If you are particularly familiar with the patch machine industry, we have special technical consultants to answer the technical questions you want. If you want to move into this industry, we also have special personnel who can provide some information about the patch machine to make you more familiar with the pick and place machine
2)Service in sales refers to that you have paid a deposit in advance, and after the production of your products, we will regularly share the progress of product production with you. Of course, if you have other requirements during this period, you can also say it, and then we will make your expectations for the products.
3)After sales service refers to all the services we provide when you receive the products. We have a special after-sales department to serve you, such as guiding installation, training employees, regular follow-up, sharing industry information and so on.
ETON as the leading manufacturer of global photo electronic high speed pick and place machine, the products are exported more than 20 countries and regions, including India, Vietnam, Tunisia, Egypt, Turkey, Russia, Thailand, etc.Take India as an example,We have many big clients in India, Such as RK,SURYA,Fiem,Calcom,POLYCRB, etc. We have sold over a hundred machines to India.
