4 PCB Design Rules Of Utmost Importance - Miracle Electronics

1
Designing a PCB can be a very challenging job, as
it requires extreme care while mentioning all
the detailing. One small mistake and the entire
board can malfunction, causing the entire
application to fail. This is why you should be
hiring sureshot experienced and reliable PCB
manufacturers to design and manufacture the PCBs
for your application.
Miracle Electronics tops the list of the best PCB
manufacturers from India, where you have a team
of skilled designers with whom you can sit and
discuss on your requirements, and expert
engineers who can translate your requirements
into a product. Also, if you have such an
authorized manufacturer handling your job,
youll have nothing to worry about as you can
rest assured that your product is being examined
and tested at every stage to ensure perfect
manufacturing. Every designing rule is taken care
of, and any violations, identified and tackled
at the earliest. Just in case you are inquisitive
to know, well let you know in this blog about
the most common PCB design rules, which if
violated, can cause serious damage. Copper
spacing and trace width

Copper spacing, which refers to the air gap
between two adjacent copper features, and the
trace width, which refers to the width of a
copper feature and conductors, should be
perfectly calculated. For example, the minimum
copper space and trace width for 1 ounce of
finished copper weight should be 0.005 for 2
ounce should be 0.006 for 3 ounce should be
0.010 and for 4 ounce should be 0.012. Zero
exposure of copper Any amount of exposed copper
on the PCBs edge or the inside of cut-outs, and
the inside of non-plated drill holes can be
problematic. To avoid this, certain instructions
need to be followed. For example, single boards,
tab-routed arrayed boards, and boards with
cut-outs should have both the outer and inner
copper layers at least 10 mils away from the
center of the board edge, in order to prevent
exposed copper. Drill hole measurements and
spacing Drill holes that are small or too close
to other drill holes can create problems. There
should thus be a minimum of 10 mils edge-to-edge
spacing between drilled holes, having a diameter
of less than 65 mils or the drill bits can break
during high speed drilling. Annular ring
measurements The annular ring is the portion of
conductive material that surrounds a hole. A
minimum of 0.005 and 0.007 is required for an
annular ring for vias and component holes
respectively. Moreover, the vias with connecting
traces should have a pad that is 10 mils larger
than their drill, and the component holes with
electrical connections should have a pad that is
14 mils larger than their drill. On the other
hand, tooling holes with no electrical
connections can have a 0 mil annular ring. These
are the four most common design features that
need to be certainly followed in order to have a
skillfully performing PCB. And, when you have one
of the best PCB manufacturers from India
handling the job, every other detail is also
considered to ensure that every aspect of quality
management is followed. This is why you must
always hire only an expert and experienced PCB
manufacturer for the job.
