In this post we shall observe certain important tasks while assembling the circuit design on the selected PCB for our project. Next to procurement of all the necessary circuit elements that have been designed to go into the circuit for assembling, the following preparatory tasks to be performed for successful assembling of the project.

The solder

The components have to be soldered on the PCB for making electrical contacts. Here two purposes are taken care of namely, as said earlier, making electrical contacts with the components as required by the circuit design and the other is firmly holding the components to the board and prevents from falling off or dangling loosely thereby avoiding instability of the components. The components get firm footage on the board and stand or lie steady.

Right solder

Always make use of good solder for making joints. In this regard for PCB soldering purpose 60/40 solder is preferable. That is 60% tin and 40% lead combination makes strong bonding apart from making good electrical contact between the component terminals and the PCB copper track. The soldering will be very shiny and smooth. Further this solder melts at sufficiently low hot iron and thereby making good solder contact. Preferably dry solder is avoided if you use this combination of solder wire.

Soldering paste

Some use soldering paste when making soldering on PCB. Applying soldering paste on the terminals and joining points clean the surface and removes any greasy matter with the wire terminals and thereby making good solder contact. High quality rosin cored 60/40 solder is readily available in the market and one can purchase that and use it instead of using separate paste. Anyhow and at any cost making dry solder should be avoided as it will create peculiar and intolerable performance of the circuit and future complications may be avoided. As such one should give much importance to soldering on PCB.

Many types of soldering irons are available in the market. Each specific type is meant for specific purpose of soldering.  For our PCB soldering purpose ordinary 10 to 15 Watts soldering iron with round or small flat tip based iron will serve the purpose. More than 75W soldering iron may be required for heavy duty soldering purpose.   Almost all soldering irons are electrically operated. Hence soldering iron should have proper earth connection with the power supply to avoid shock as well as safe while soldering CMOS ICs.

Maintenance of soldering iron

Maintenance of soldering iron is very important aspect for effective and quick soldering work. The tip of the soldering iron should be cleaned then and there and especially when it is hot. Clean tip makes the work perfect and gives quick and efficient soldering joints, which is a successful trick for the project to function as desired.

The tip of the iron should be sufficiently hot so that the solder should melt easily and flow around the joints when attempting soldering. Low or insufficient heat will make dry joints which should be avoided. Apply heat and solder simultaneously to make joints. Please do not take solder on the iron to the terminal and solder it. The other way is the correct method of soldering.

In this post we have widely discussed how best we can make use of the soldering technique for successful assembling. In our coming post we shall learn more hints on successful assembling technique.
