1Things To Do And Not To Do While Manufacturing
PCBs - Miracle Electronics
Printed Circuit Boards or PCBs are critical
components of almost every electronic device,
which determines its success or failure.
Different components are connected with one
another on a PCB using circuits and copper
traces, bringing the device to life. Therefore,
we can say that the PCB is the soul of an
electronic body. And, this makes the PCB
designing and layout the most important aspects
of a successful device.
Everything in terms of materials, size,
dimensions, thickness, layers, planes, and
connectivity must be considered, thought of, and
mentioned within the design. Also, the PCB design
takes all kinds of electrical and mechanical
constraints into consideration when laying out a
board for its desired form, fit, and function.
However, with devices becoming smaller and
smaller over time, PCBs are also becoming
smaller, which makes designing and debugging a PCB
2more difficult and complex. This is why even more
careful planning is important, while ensuring
that you have a design-for-test strategy. Here,
you may need to hire manufacturers of PCB
assembly from Germany, one like Miracle
Electronics, who have professional designing and
testing engineering teams who work
collaboratively to bring up the most successful
products. Hiring such professionals can help
you overcome the very common PCB manufacturing
pitfalls, which you may encounter otherwise. For
example, ? If an edge-piece is trimmed too
close, removing the cover and exposing the
copper layer, it can cause insufficient
copper-to- edge clearance. The cover functions
as a protective layer of copper against
corrosion. There must be some space between the
edge of copper and edge of the board, so that
there is no likely risk of shorts during
de-panelization. ? Slivers on the PCB can cause
serious damage and may have a fatal functioning
of the circuit board. This could occur in two
ways during the etching process either by
strips of too thin copper or solder mask
detaching before dissolving and contaminating the
chemical bath or by cutting an area of the
board too deep or too thin. To contradict such
situation, it is important that you design
sections with minimum widths. ? When the
copper-coated holes in the PCB have
imperfections, plating voids occur. The general
function of these holes is to allow current flow
from one side of the circuit board to the other,
which becomes ineffective if the copper
deposition is not perfect, or has
3air bubbles, or is contaminated. Thus, it is
essential that the material is thoroughly
cleaned after drilling the holes. ? Any amount of
insufficient solder mask dams can lead to a
number of issues. Thus, you must be very sure to
verify and eliminate them, or it may result in
solder shorts between fine pitch leads. ? There
must be no acute angles in your design, because
any such presence can cause acid to be trapped
during the etching process, making the circuit
defective. These are only the most common
pitfalls that are observed during PCB
manufacturing. There could be many other minor
faults in the process that may lead to hazardous
outcomes. To prevent all such situations, it is
always better to hire professionals for the job.
So, rely on specialized technicians if you want
to have the best practices being utilized for
your PCB manufacturing. For more Information
