Give due attention to diodes and electrolytic capacitors as they are polarity dependent.ĭo the soldering of other components in the same way while keeping in mind that components with long and sensitive leads like capacitors and transistors are soldered last. Start from left most corner of PCB and solder the components one by one on their correct position on PCB.īefore soldering any component see that you have placed it at its right position and with correct polarity. This is to make mounting and dismounting of ICs easy while troubleshooting. ![]() Not ICs but their sockets are to be soldered on PCB. If yes only then proceed further to actually mounting and soldering the parts. But usually values are specified numerically on them.Ĭan you make out the whole working of circuit and are you able to identify each component separately as to where each of them has to be placed? There are different methods in which values are defined on capacitors. The color band on each resistor corresponds to its exact value. ![]() Identification of resistors is done by color coding. Each component has to be soldered in its position on PCB. Also have look at PCB and components supplied along with the kit. It is typically a good habit to have red wire be exclusively power and black exclusively. ![]() Next, make power and ground connections to the chip as shown to the right. For a refresher on how to insert chips into board, see Part V. First of all read the given manual thoroughly and study the circuit given in the figure. First we will start by inserting the chip into the breadboard as shown at left.
