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.

Testing of components

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.
