Steps in assembling process
We have so far elaborately discussed the great task of
fabrication of PCB of a circuit design and successfully learnt the art of
making PCB for our project work. With this ready made PCB, we are ready to
assemble the circuit schematic on the PCB. Assembling the circuit schematic on
the board is also an important task to put our gadget to work satisfactorily.
As such the assembling process also involves many steps. In this post we shall observe and learn such important
steps and the procedures to be followed for successful assembling the schematic
to put the completed one to perform as it should be.
Steps in assembling work
We shall discuss here the important steps involved in
assembling the project design. Some of the important steps that one should take
before assembling are listed below. Procuring the appropriate and right components,
testing of the components if necessary prior to hooking up on the board,
selection of proper solder and iron for soldering work, observing precautions
in soldering some of the vital and sensitive components, validating the hooking
up process and finally finishing the assembly work for sustained work and for
optimum performance are some of the steps to be followed in assembling work.
Procurement of components
After getting ready the concerned PCB for which the
circuit design has been made, all the component elements that go into the board
are to be listed as per the specific circuit diagram of the project which we
are going to assemble for procurement. The list may include ICs, transistors,
diodes, capacitors, resistances, LEDs, relays, transformers, power supply
sources such as batteries and connecting wires including the appropriate grade
solder etc. One should procure the circuit elements and associated items from
the local electronics mart. Once these items are procured completely, then only
the assembling work should be started.
Ensuring availability
Sometimes certain vital components may not be readily
available from the local market. Arrangements should be made to procure such
locally not available components from the original sources where it is
manufactured. Sometimes we ourselves have to locally get ready the items if
possible and should be home made and available at the time of assembling work.
One may not be able to start the assembling work if particular important schematic
components like IC or transistor are not available as sometimes due to scarcity
or manufacturing of such items are stopped by the manufacturer themselves. Availability of components has to be ensured
or at least equivalent components should be made available. Sometimes homemade/handmade
components are required to be prepared at home for the assembling. For anything
all the items should be made available for assembling. For want of components
the assembling work should not be stopped.

Another important task with the components procured is
its working condition. Defective or under performed items should be discarded
and only quality component should be used for satisfactory performance of the gadget
which we are going to assemble. To ensure quality and if necessary the
components may be checked for its, continuity, short/open condition etc., to
avoid later on confusion, delay and for cost effectiveness. Future
complications in the performance of the circuit can be avoided by prior checking
the vital components before soldering.
As such procurement of good quality components prior to
assembling is one of the major tasks and to be carried out as a first step in
successful assembling of PCB of your favourite project. We shall discus the
other steps in our coming posts.
