What You Should Know About Surface Mount Technology

We are living in an age where scientific progress has been quite astounding and the scientists are coming up with modern devices and apparatuses. Working of these devices and apparatuses is entirely based upon the new findings. The use of printed circuit board has changed the mechanism of all major devices. They have become smaller yet more powerful and the credit for that should go to the scientific development. However, the best is yet to come.

Surface Mount Technology or SMT has been a way of creating electronic circuits in such a manner where the components are placed one over another on the printed circuit board. The devices that are made on this technique or technology are termed as Surface Mount Devices. The components can be placed or used on the same board. However, the technicians take special care for installing the bigger components like larger transformers and power semiconductors. The technicians use SMT as a component that is relatively smaller that the other technology which is known as Through-Hole (TH) technique. Instead of general fixing methods, they use short pins and solder balls to fix these components on the board.

As said earlier, the SMT technique is different from Through-hole techniques. The difference lies in the components also that are used in these techniques. The major equipment for SMT include the following:

• Pick-and-Place Machine

• Equipment for Soldering SMT/ Soldering iron

• Equipment for Re-flow Soldering

• Equipment for Cleaning solvent in SM Technology

• Solder-Paste Screen Printer for SMT Stencil Printer

• Baking and Curing Oven for SM Technology

• Inspection and Repairing Equipment for SM Technology

Since the Surface Mount Devices (SMD) are the parts and parcels of SMT, therefore the components attached with with SMD also remain connected to the SMT. These components include:

• Surface Mount Resistors and Capacitors

• Plastic Leaded Chip Carriers (PLCC)

• Leadless Ceramic Chip Carriers (LCCC)

• Ball Grid Array (BGA)

• Ceramic Leaded Chip Carriers (CLCC)

• Small Outline Transistors (SOT)

• Small Outline Integrated Circuit (SOIC and SOP)

• Small Outline J Packages (SOJ)

• Fine Pitch SMD Packages (QFP, SQFP)

Modern Uses/ Applications:

Since the technology behind SMT is proven time and again, therefore more and more electronic companies are showing a readiness towards using the technology in the forthcoming products. Both LED and LCD televisions use the SMT techniques and the results are quite evident to us. These televisions have better technical utilities than their predecessors. The technology powers the Printed Circuit Boards that are separately useful for modern lighting devices that are used in the public places. These lights get more intensity without consuming much power.

With the on-going efforts of the scientists, you can always expect better equipments would come in due course of time which will be more efficient than what we find around us at present. As far as the utilities of SMT stencil printer by Millennium Circuits Limited is concerned, it has been adopted in the bigger printing organizations. They are better than the existing ones.
