Introduction to Rapid Metal core PCB Prototyping
What Exactly is Rapid Metal core PCB Prototyping?
The idea behind rapid metal core PCB or rigid printed circuit board
(PCB) prototyping is to develop sample circuit board assemblies which can be
used as the models for manufacturing brand-new products. The reason that a
prototype needs to be developed quickly and with maximum flexibility built in,
is so that specific ideas can be implemented, tested, and then modified as
needed. In most cases, rapid PCB prototyping can be completed in less than a
week, and sometimes far less than that, depending on the complexity of the
desired assembly, and the PCB manufacturing objectives.
How it works
In the first step, computer-aided design (CAD) software uses specific layout data as its input to generate a number of circuit board prototypes. After having chosen the most desirable circuit board material for the project, fabrication of the actual PCB can begin. In the next phase, either a laser system or circuit board plotter is used to impose the layout of circuitry on the circuit board material.
For most applications, a circuit board
plotter would be used, and for those involving RF applications or ultra-fine
structures, a laser system would be a better choice. In this manner, circuit
boards can be imprinted on either a single side or on both sides before testing
begins. During testing, the conducting paths of the circuitry provide test
results which indicate whether or not modifications are necessary to achieve
the objectives of the PCB.
Why quick turn PCB prototyping is so
advantageous
In the past, electronic design and
manufacturing wasn’t nearly so efficient, with quick turn PCB prototypes taking weeks to
develop and test, and as everyone knows who’s associated with a business
enterprise, time is money. Getting new ideas to market in the shortest time
possible is pretty much the default mantra where electronics are concerned.
Compared to the development life cycle of a decade or two ago, rapid PCB
prototyping is lightning fast, and can literally be accomplished in as little
as a few hours, depending on the extent of testing.
Another advantage is that even the most
diverse and complicated circuit board designs are manageable through this kind
of prototyping. Since the CAD software does all the real design work in
super-fast time, more emphasis can be placed on the testing and modification
phase to achieve the desired results, and fine-tune the design.
