Final tricks and tips of sure shot assembling technique

We are on the process of discussing important tips to enable us to assemble the circuit schematics on the selected PCB for optimum performance and to get its utility value.  In this aspect we shall go through certain additional tips that will fetch you good working condition of the project in our assembling and construction work.

Bending the components

There may be some occasions where we have to bend the terminals of the circuit elements that go into the PCB before inserting into the holes for soldering purpose. Before inserting certain components, we may require them to bend its terminals suitable in length, so that the terminals of the components go into the appropriate holes in the PCB.

 

Care should be taken to bend the terminals to just required and should not be twisted indiscriminately as otherwise the terminals may dislodge from the component and become useless. Then the component may become useless and a new one has to be replaced. This tells upon the cost of the project as we may have to incur more expenses in procuring another one to replace the damaged one. This is especially true with transistors and ICs which are costlier and dearer.  

The leads or the terminals should be neatly and appropriately bend so that it should not be a hindrance to other components, as otherwise it may short with some other component leads and the circuit may become dead.

Further extra length of the leads of the components like resistors, capacitors after soldering into the PCB  should be trimmed neatly so that it looks good besides avoiding shorts with other component leads.

Use of sleeves

It is a good idea that the leads may be covered with sleeves of insulated material like plastic so that the bare opening may be avoided. Sleeves, especially for vital components are absolutely required for good project building work. Wherever component leads require sleeves it should be used for safety of performance. It also avoids fire hazards when they come into contact with bare terminals and short circuited.

Fixing with screws and nuts

Some power transistors and ICs may require heat sinks to be fixed on the body for heat dissipation. In certain assembly work heat sinks may be directly soldered on PCB if provision is available, otherwise it should be neatly fastened to the body with bolts and nuts.  Only recommended set of heat sinks should be used which come with set of screws and bolts. Also it is recommended to use heat sink paste with the components for optimum performance.

Cabinet

Last but not the least is housing the project in the appropriate cabinets. For every project to give professional look, appropriate cabinet should be used to house the assembled projects. Without cabinet it may look crude and does not pass quality control approval. Metal cases, wood cases or plastic cases can be used as cabinet depends upon the project and the gadgets.  The Cabinet is used predominantly to avoid electric shock and heat and fire hazards.

Conclusion

We have so far elaborately discussed almost all the vital tips and tricks for successful and efficient assembling of circuit designs with my designed PCBs. I am sure that the above discussions will definitely give utmost confidence in successful project building by anyone who are interested in electronics.
