2. • A printed circuit board is a self contained model of
electrical support to surface mounted and socketed
components in the electrical devices. The significance
and combination of design, fabrication and customer
demand of Printed Circuit Board plays a vital role in
developing an exact product as specified by the
customer. A trend of complete turnkey has been
adopted in the market right from control
conceptualization, design, surface mount or through-
hole technique, assembling, testing and delivery of
order to the customer.
3. • There are international standards followed to maintain an
assurance over quality as well as durability in the printed
circuit board. This solely depends on the type and level of
design created for a prototype. The challenges faced at the
time of fabrication like inadequate fiducials ( reference
point ) , polarity , hole size, tabs, proper paneling , dry
parts, vias in pads, large deltas, thermal relief , leadless
devices, close proximity of devices, trace cuts, proper
finishing and clear laminate stack solely depends on the
blueprint and the design of the prototype.
4. PCB fabrication process
• Every product or prototype has a different layout as
per the space allocation. There are special software
to design the circuit model on the board. Raw
materials are then arranged as per the volume of
the production, the type of product and purpose of
the product. According to the circuit pattern and
model the quantity and quality of inputs are
decided. This is a significant criterion to be
considered to make the project a cost effective and
qualitative one.
5. • One can move forward with the PCB fab process after
proper planning , design and adequate availability of
raw materials .There are different types of process used
for different kinds of PCB’s like two –sided, one sided
and multilayered . To get started with the fabrication
process the glass fiber is rolled to a particular thickness
as per the design. The substrate material is curved by
passing it to an oven. After that the layering of the
copper foil are placed as per the size of the board. With
this the holes are drilled on the layers as per the design
and layout.
6. • The copper is plated with the help of an additive or
subtractive process. The inner layer core, copper foil
and prepreg are combined together with vacuum,
heat or pressure to laminate them thoroughly. This is
when the PCB is to be fabricated with multi layers. The
copper plating creates metallic base onto the holes
and surface of the board. The outer layer is then
coated with the same type of foil used in inner coating
of the layers in circuit board. Tin plating is done to
maintain the traces , pads and walls while operating
onto the outer layer .
7. • The strip-etch-strip process is used to remove
developed dry resist from the coatings where the
tin plate is not affected. Solder mask technique is
being applied to level the panel. The CNC machine
is used to cut the boards in equal sizes as per the
PCB design and layout. At last the boards are tested
for its durability and raggedness.
8. • The fabrication process depends on the volume of orders
and demand of the PCB assembly or fabrication services to
make it a cost effective and qualitative one. There is a
growing demand of innovative and strategic business models
in dominant industries of USA. The demand of PCB
fabrication service in USA has shown a remarkable growth in
terms of quality of offerings and innovation. The business in
user industries generated new orders in PCB fab in California
. Thus current market trend is a fusion of various
technologies for an error-free, optimal used resources and
quick turnaround for the customers.
