The definition of SMT
SMT is the surface assembly technology,surface mount technology(surface mount technology)(Surface Mounted
Technology abbreviation),is currently the most popular electronic assembly industry,a technology and technology.
What are the characteristics of SMT?
High density,electronic products,small size,light weight,the size and weight of the chip components only traditional packaging components around 1/10,the general use of SMT,the electronic product volume reduction of 40%to 60%,weight reduction of 60%~80%.
High reliability,strong anti-vibration ability.Poor solder joint defect rate.
High frequency characteristics.Reduced electromagnetic and RF interference.
Easy to achieve automation,improve production efficiency.Reduce the cost of 30%to 50%.Saving materials,energy,equipment,manpower,time and so on.
Why use SMT
The pursuit of miniaturization of electronic products,previously used perforation plug-in components have been unable to narrow.
Electronic products function more complete,the use of integrated circuits(IC)has no perforation components,especially large-scale,highly integrated IC,had to use surface patch components.
Product quality,production automation,the factory to low-cost high-yield,quality products to meet customer needs and enhance the competitiveness of the market development of electronic components,integrated circuit(IC)development,semiconductor materials,multiple applications.}
Electronic technology revolution is imperative to chase the international trend.

SMT basic process components:
Silk screen(or dispensing)-placement-(curing)-reflow soldering-cleaning-testing-repair
Screen printing:its role is to paste or patch solder paste printed on the PCB pad,the components for the welding to prepare.The equipment used is silk screen(screen printing machine),located in the front of the SMT production line.
Dispensing:it is the glue drops to the fixed position of the PCB,the main role is to fixed components to the PCB board.The equipment used is the dispenser,located at the front of the SMT production line or after the testing equipment
surface.
Placement:Its role is to accurately mount the surface assembly components to a fixed location on the PCB.The equipment used is a placement machine,located in the SMT production line behind the silk screen machine.
Curing:Its role is to melt the patch,so that the surface assembly components and PCB board firmly bonded together.The equipment used is a curing furnace,located in the SMT production line in the back of the placement machine.
Reflow soldering:its role is to melt the paste,so that the surface assembly components and PCB board firmly bonded together.The equipment used is a reflow oven,located behind the Mounter in the SMT production line.
Cleaning:its role is to assemble the PCB board above the human body harmful welding residues such as flux and so removed.The equipment used for the cleaning machine,the location can not be fixed,can be online or not online.
Detection:its role is to assemble the PCB board for welding quality and assembly quality testing.The equipment used is magnifying glass,microscope,on-line tester(ICT),flying probe tester,automatic optical detection
(AOI),X-RAY detection system,function tester and so on.The position can be arranged in the appropriate place of the production line according to the detection needs.
Rework:its role is to detect the failure of the PCB board rework.The tools used are soldering iron,rework station and so on.Configured anywhere in the production line.
