Shenzhen, China - September 19, 2020 - PCBONLINE, a global high-end PCB manufacturer
servicing electronics manufacturing (EMS) customers in defense, aerospace, medical,
and other high-end industries, has posted a technical blog entitled, "Comprehensive Guide
to SMT Stencils." It answers questions about what are SMT (Surface Mount Technology)
and SMT stencils and what are they used for, where do you get SMT stencils for PCB
assembly, what are the different types of SMT stencils, and how do you use SMT stencils?
Comprehensive Guide to SMT Stencils
SMT (Surface Mount Technology) stencils are very important for PCB designing
and manufacturing. If you can't decide which type of SMT stencil to go for and you
need a detailed guide for this topic, then you're in the right place. This article
will focus on every aspect of PCB stencils and by the time you reach the end, you
will develop a crystal-clear idea of using SMT stencils.
What Are SMT and SMT Stencils?
Surface Mount Technology (SMT) is a very common term used in electronic engineering.
It is a technique used to design circuit boards where the components are mounted
on top of the PCB. The usual technique of making circuit boards is the through-hole
technology where the components are fixed on the board by sliding their terminals
into holes present on the circuit board and soldering the components? legs from
the other side.
The components used in through-hole technology have longer legs since they need
to slide through the hole. On the other hand, the components used in SMT-based PCBs
have smaller legs and they are generally smaller in size as compared to regular
components.
Due to the small size of SMT components, placing them on the PCB is a sensitive
task that requires great accuracy and needs to be handled with a lot of care. SMT
stencils are a life-saver when it comes to PCB assembly and manufacturing because
they allow you to place the tiny and delicate components on the circuit board without
any hassle.
Laser cut stencils are designed according to the PCB layout and then a solder
paste is poured on top of the circuit board and while it is drying, you can place
your components on the board so that they are mounted on the PCB surface correctly.
What Are SMT Stencils Used For?
Using SMT stencils for PCB manufacturing is indeed a great choice because it
solves many problems that you would otherwise face in manual PCB assembly. The advantages
of SMT stencils include: No Short Circuits The chances of short circuiting are high
when applying the solder paste without an SMT stencil. Using one will ensure that
there are no short circuits in your PCB.

No Gaps in Soldering Process
Laser cut stencils allow you to apply a smooth layer of solder paste which leaves
no gaps in the soldering process.
