1. Why is SMT a widely used option for PCB assembly?
Printed circuit boards have been used across the world for years but the way they have been
manufactured has changed over time and it’s essential that you become acquainted with the
different methods for the same before you select a feasible option according to your necessities.
It is basically the process of attaching printed circuit boards with your electronic components.
There are two methods of this PCB assembly. Both are widely used due to their applications in
the industry.
Through Whole construction
Point to point construction was replaced by through-hole construction. It is used for the process
of soldering the leads of components with the pads, which are placed on the other side of the
PCB. The use of mounting machines is common for the same. There might be cases however,
which require additive precision and this is when the assembly is done by hands as well.
SMT technique
Surface mount technology is also widely used for PCB assembly. It is done by directly attaching
components to the PCB. They are used at smaller denominations and used for intricate PCB
boards where there might be few or no leads used. In that place, there are pins, solder balls and
even flat contacts used.
Benefits
Being of a relatively smaller scale makes SMT technology all the more functional. They have a
larger number of connections and this makes it possible for them to be used at a wider gyre.

2. Components can be placed at either sides of the printed circuit board and this is what tends to
make them all the more useful. They are relatively cost effective when compared with the other
modes of printed board circuit assembly.
It would be right to say that this is a much more streamlined manner of PCB assembly services.
It has definitely cut short on time and money for electronic manufacturers and this has helped
the productivity to increase manifold.
All you need to do is consider various options before you decide on something. Analyzing your
type of requirement, and focusing on getting your work done in the most efficient manner, shall
help you choose better. This way you shall be able to find the most suited option according to
your specific requirement and help you form the best PCB assembly boards. Researching well
shall also help you land on the most befitting option according to your specific industrial
requirements.
