Technology has been continuously evolving, and the
same is true for soldering as well. The most popular type of soldering process these
days is surface mount technology, wherein all the components are simultaneously
soldered onto a printed circuit board. However, it may not allow for highly
precise soldering applications. It is for this reason that many manufacturers
have gone back to adopting selective, through-hole soldering. Here are top
three benefits of selective soldering.
Benefit
#1: Precision
Selective soldering allows forming a conductive bond
on a printed circuit board at specific locations. It essentially means that
while all other components can be wave soldered, some through-hole components at
particular places can be selectively soldered, achieving high efficiency of
joint and precision.
Benefit
#2: Workability
Selective soldering is preferred by many manufacturers, even though it
has to be done manually because this technology is not very costly. The
through-hole pins and paraphernalia are also not as sensitive as its more
famous counterpart – the surface mount technology.
Benefit
#3: Process optimization
Because selective soldering allows the technicians
to target specific regions or areas on a printed circuit board, it induces
repeatability into the process and leads to higher throughput and fewer
defects. The best thing is that it can be automated, allowing for the
elimination of human errors.
The reasons listed above demonstrate that selective
soldering is ideal for through-hole applications.
