Good soldering skills is a must for all electronics aspirant technicians. However, this skills is not that easy to gain as compared to how you see it. It requires practice and patience in order to acquire necessary skill to do it right. Below is a video on how to atleast do basic soldering and desoldering.
ACTIVATION
Do - It - Yourself: Preparing for Soldering Activity
Given:
In digital electronics, a flip-flop is a bistable multivibrator that can store state information. It is a fundamental building blocks of digital electronics systems used in computers, communications and etc.
However, in this activity we will used this flip-flop circuit in a different application.
Directions:
Borrow or Buy the following tools and materials for the soldering activity.
Identify and then buy the components given in the schematic diagram above.
For the Light Emitting Diode (LED), buy two different colors with 10 pieces per color.
For the other components, you will be the one to identify them.
TOOLS
Soldering Iron (40 - 60 Watts)
Soldering Stand
DeSoldering Pump
Mini Drill
Utility Blade/Knife
Hacksaw
MATERIALS
Soldering Lead (2 Meters)
Soldering Paste (Small Size)
Sponge
PCB (2 inches x 2 inches)
Masking Tape
Facemask
Ferric Chloride Solution

APPLICATION
Do - It - Yourself: BASIC SOLDERING & DESOLDERING
Given:
flip-flop2.mp4Flip-Flop Circuit
In this activity, you will make an initial of your name or anything you like with the use of this flip-flop circuit. Examples are; emoticons and the like.
If you still don't have an idea, just watch the video.
Directions:
Remember the PCB designing activity in the week 1. We will perform the same thing in this activity.
After having or finishing the designing and lay-outing of the circuit. We will proceed to boring of holes in your PCB for you to mount the components in the next step.
Mount the components in their respective placement in the PCB. Use the sequence below in mounting the components.
Resistors
Capacitors
Transistors
LED's
After mounting the resistor, the next step to do is soldering it one after the other. Then proceed to the next components.
Considering that you already mounted all the components. The next step is to test the circuit by putting a supply using a 9 volts battery.
