PCBs can have or two copper layers, based on which they can be called single sided or double sided. Typically, the main insulating substrate used in PCBs is “FR-4 glass epoxy”.

2. A printed circuit board (PCB) is intended to connect and support varied
kinds of electronic components with the help of conductive elements. Most
of the electronic components are soldered on the PCB or may be embedded
in what is known as the substrate. PCBs can have or two copper layers,
based on which they can be called single sided or double sided. Typically,
the main insulating substrate used in PCBs is “FR-4 glass epoxy”.

3. Printed circuit boards, as mentioned, are a
must in the electronic industry. While there
are other alternatives such as ‘point to point
construction’, printed circuit boards are
effective an extremely useful for varied kinds
of production needs. Typically, PCBs come in a
wide range of specifications, and are
customizable to fit your specific needs. PCBs
require design effort on part of the
manufacturer to get the right kind of circuit.

4. All PCB manufacturing services are not
the same, and therefore, expertise is an
aspect you cannot compromise with. You
also need to understand their client base,
because that can tell a lot about the
kind of work they have done so far.

5. PCB manufacturers are expected to be transparent and extremely honest
with their clients as far as quality tests are concerned. If required, they
must be willing to discuss their testing process in detail. Also, the pricing
should be as flexible as possible.
