Surface Mount PCB Assembly is a procedure in electronic manufacturing in which electronic circuits are produced. This is done by placing the modules in direct contact of the surface of PCB/ Printed Circuit Board.

Surface Mounting was originally knows as planar mounting. Earlier, the method that was applied was the fitting of components in the printed circuit board with the wires punched through a hole. This was the ‘through-hole technology’ that was largely followed. But over the years, this has been replaced by the SMT PCB Assembly mode.

Surface Mount Printed Circuit Board Assembly is basically a technique of packaging of the circuit board where on top of the board lead wires or chips or pins (the several components) are soldered on. In the case of the SMT PCB Assembly, they are considered to be faster and efficient than the ‘through hole’ technology of placing the pins. The lead chips and pins are soldered directly through the board and are placed underneath it. Because of this method no holes are drilled atop the board and the real estate underneath the device can also be put to use on other layers of boards.

The Surface mount component can vary from smaller pins or lead chips or even solder balls. The BGA Assembly, in other words- Ball Grid Array-is another popular chip. This is basically used for integrated circuits as they provide more interconnected pins. As a result, the whole surface area as well as the bottom surface of the board can be utilized. The ball leads are shorter in size and they are soldered in the board with precise automated process. Thus, they are very efficient and provide one with a higher speed.

Surface-mount PCB Assembly refers to the process of manufacturing and designing PCBs or Printed Circuit Boards without drilling holes as in the Pin Through-Hole method. Instead, the components that require soldering are mounted directly over the surface of the PCBs. The components thus formed, are more minute and smaller than their PTH counterparts as they do not require making holes and may or may not contain leads. The equipment or accouterments required to carry out SMT comprise reflow oven, solder paste screen printer, inspection equipments, repair tools, solven cleaning products and the likes.
What to Consider while Designing an SMT

One of the main considerations while undergoing any electromechanical assembly is the thermal compatibility and this holds true for SMT as well. The packaging of the Surface Mount PCB products is something which requires attention for checking into the thermal issues.
The reliability of the final product is largely dependent on packaging as with increase in the density of the latter, there is bound to be thermal problems which affect the PCB in the whole. PCBs assembled using SMT are made of FR-4 Glass Epoxy Substrates which tend to react with ceramic packaging leading to reliability issues of the solder-joint. The CAD system is also something that needs to be considered while manufacturing SMT PCBs. Packaging moisture density, market requirements are other things which are looked into by designers before carrying out SMT assembly of PCBs.
Advantages of SMT PCB

Surface mount technology of PCB design and manufacture comes with a number of benefits making this method a more preferable one than the Through-hole one. The components of the SMT PCBs are much lighter in weight and consequently occupy much lesser space than the through-hole ones. Moreover, due to the attenuated space taken up by the components the cost for board also reduces considerably thus leading to overall saving.

Through Hole Versus Surface Mount PCB Assembly

While enlightening yourself about the fundamentals of Electronic and Electromechanical Assembly, you need to understand the basics of two of the most important technologies- that of Surface Mount and Through Hole. The two are methods of performing Printed Circuit Board Assemblies and are largely performed by contract PCB assembly companies. Take a look at the discussion concerning the two.
Through-Hole Technology
Through-hole technology of PCB Assembly embraces drilling of the components into the Printed Circuit Board through holes by using lead. It is followed by a soldering process, through manual or automated insertion by machines.

Surface Mount PCB Assembly
The Surface Mount technology involves the intricate soldering of the PCB by mounting the components atop the board. The PCB in Surface-Mount technology comprises solder copper pads or flat pads plated with tin, lead or gold which come without holes. Reputed contract electronic manufacturers like Denis Ferranti use solder pastes and fluxes which are soluble in water in order to attenuate the efforts of the residue cleaning.

Advantages of Surface Mount over Through-Hole
The advent of the Surface Mount PCB Assembly technology has brought forth many benefits with relation to cost and design of the Printed Circuit Boards and is thus replacing Through-hole technologies in most electronic manufacturing companies. One of the main advantages with the Surface-Mount technology is the small size of the components with density higher than their through-hole counterparts. The small size of the components makes them take up smaller areas or spaces on the PCBs which also leads to considerable cost-cutting. The weight of the SMT components has been found to be about one-tenth of those for through-hole assembly. Surface mount leads to a considerable reduction of vibration, shock and electrical noise as well. Not to speak of the handsome reduction in costs which is brought about by way of manufacturing through use of lesser holes and smaller board, large volumes of production, lesser material handling and many more.

The Great Technology- Surface Mount Assembly

admin — Tue, 25 Sep 2012 09:01:44 +0000

Surface Mount Assembly or the technology is a method to construct electronic circuit in which the materials are organized directly onto the surfacing area of printed circuit boards. Any electronic device which is made in this way is termed a surface mount device. In the manufacturing organization it has highly replaced the “hole” technology producing technique of setting components wire pioneers into holes in those circuit boards. Both methods can be handled on the similar board for materials not matched to surface organizing like semiconductors of power and the transformers. As the SMT component and Contract Electronic Manufacturing Services are generally smaller than its own through-hole complementary part, it has either little leads or nothing at all. SMT component may have some leads of styles or short pins, BGAs, flat contacts or conclusion on the figure of the component.

Surface Mount Assembly was industrialized in the 1960s and appeared extensively used in the end of the 1980s. Most of the leading work in that technology was done by IBM. The design technique was first revealed by IBM in the year 1960 in a little scale computer and it was later used in the Launch Vehicle Digital Computer which is used in the influent unit that leaded all Saturn V and Saturn IB vehicles. The components were unthinkingly redesigned to have a little metal tabs or the caps which are used at the end that could easily be soldered to the surfacing area of those PCBs. By this components become much smaller and the components placements on the each of two sides of the board appear as much more common with the organizing surface than through-hole organizing and permitting much higher densities of circuit. Sometimes only the joints of the solders hold the part to the boards but parts on the second side or on the bottom side of that board are temporarily went out of danger with some dots of glue as well. SMDs and Contract Electronic Manufacturing Services are generally built physically light and small for that reason.
