Specifications
SMT refers to surface mount technology, which is the most popular technology and production process applied in the circuit board assembly line. In the pick and place system, it is the circuit
assembly technology that mounts no-lead or short-lead surface assembly components on the surface of a printed circuit board or other substrates, then solders and assembles them by reflow soldering
or IP soldering. The advantages of SMT chip mounter: high assembly density, the small size of electronic products, lightweight, high reliability, strong vibration resistance, easy to realize
automation, help customers improve production efficiency, reduce costs by 30%-50% by saving materials, energy equipment, manpower, time, etc.

THE ADVANTAGES OF SMT ASSEMBLY
SMD assembly device makes the creation and production of electronic circuits easier. Surface mount technology machines are especially important in complex circuits. Higher levels of automation have
saved our entire industry time and money. Smaller size and reduced weight are the two main advantages of SMT. Components can be more closely aligned, and the final product will be more compact and
lighter.
The main advantages of SMT Assembly:
1. Automatic correction of component placement: the surface tension of the solder forces the component to align with the pad. This reduces placement errors.
2. The cost of the smaller SMD or component is lower than its larger through-hole version. You can combine through-hole and SMT manufacturing on the same board to achieve greater functionality.
3. Smaller deliverables and lower lead induction provide you with a smaller radiation loop area, resulting in better electromagnetic compatibility.
4. Faster production setup-assembly can be carried out without drilling the circuit board. Higher circuit speed-most manufacturers regard this as the number one advantage. Through the
standardization of design and components, manufacturing automation can be achieved.
5. Lower resistance: inductance-high frequency performance reduces the undesirable consequences of RF signals. Reducing or eliminating drilling, shortening the set-up time can increase the
manufacturing speed. Multitasking-high-end components are more versatile.
6. More components can be placed on both sides of the board, creating more connections for each component. The electronics assembly line machines (surface mount assembly equipment) requires fewer
circuit boards. Welding can be customized. The components are connected with solder, which is also glue. Better performance can be achieved under shock or vibration mechanical conditions. SMT
connection is more reliable.
SMT ASSEMBLY PROCESS
The assembly process of SMT and its process flow mainly depend on the type of surface mount component (SMA), the types of components used, and the conditions of assembly equipment. In general, SMA
can be divided into three types of single-sided mixed assembly, double-sided mixed assembly and full-surface assembly, a total of six assembly processes. Different types of SMA have different SMT
assembly process, and the same type of SMA can also have different SMT assembly process.
Choosing an appropriate assembly method according to the specific requirements of the patch processing and assembly products and the conditions of the surface mount machines are the basis for
efficient and low-cost assembly and production. It is also the main content of the SMT process design.
1. Single-sided hybrid assembly method
The first type is single-sided hybrid assembly that is SMC/SMD and through-hole plug-in components (17HC) are distributed on different sides of the PCB, but the welding surface is only one-sided.
This type of assembly process all use single-sided PCB and wave soldering (currently double-wave soldering is generally used).
2. Double-sided hybrid assembly method
The second type is double-sided hybrid assembly. SMC/SMD and THC can be mixed and distributed on the same side of the PCB. At the same time, SMC/SMD can also be distributed on both sides of the
PCB. Double-sided hybrid assembly adopts double-sided PCB, double wave soldering or reflow soldering. In this type of assembly method, there is also a difference between the first-sticking process
and the after-sticking SMC/SMD. Generally, it is reasonable to choose according to the type of SMC/SMD and the size of the PCB. Usually, the first-sticking process is more adopted.
3. Full surface assembly method
The third type is full-surface assembly, with only SMC/SMD on the PCB and no THC. As the current components have not yet fully realized SMT, there are not many such assembly forms in practical
applications. This type of assembly method is generally assembled on a PCB or ceramic substrate with fine-line patterns, using fine-pitch devices and reflow soldering processes.
DIFFERENCE BETWEEN SMT AND SMD ASSEMBLY
SMD is the abbreviation of Surface Mounted Devices which is one of SMT (Surface Mount Technology) components, including CHIP, SOP, SOJ, PLCC, LCCC, QFP, BGA, CSP, FC, MCM etc.
Surface mount components were introduced about twenty years ago, and this opened a new era. From passive components to active components and integrated circuits, they eventually become surface
mount devices (SMD) and can be assembled by pick and place equipment. For a long time, people believed that all pin components could eventually be packaged in SMD.
SMT is the abbreviation of Surface Mount Technology which is currently the most popular technology and process in the electronics assembly industry. SMT is a new generation of electronic assembly
technology which compresses traditional electronic components into a device with a volume of only a few tenths, thus realizing high-density, high-reliability, miniaturization, low-cost, and
automatic production of electronic products. This kind of miniaturized component is called: SMD device (or SMC, chip device). The process method of assembling components on the printed board PCB is
called the SMT process.
At present, SMT technology is mainly realized through equipment which mainly includes loader machine, solder printer, automatic pick and machine, reflow oven, and various auxiliary tools and
equipment.
