WEEK 9 : SOLDERING PROCESS

Assalamualaikum for all viewers. Last week i already update all the things that i have done for drilling process. Now for this week, i will talk about soldering process. First of all, before we start the work, we have to make sure that we have every tools that we need for this process. i will list down all the tools used in this process.

Now we can start solder all the component. First put the component on the PCB and make sure that the components are in the correct position. Then switch on the soldering iron and wait for 5 minutes in order to make sure that the soldering iron is heat enough. Then put the PCB on the PCB holder so that we can easily doing the solder without having a difficulty during the process. Now we can start solder. During this work, make sure that we not put the soldering iron too long on the PCB because if too long we might give the burn to our PCB and it will damage our PCB. If we want to desolder, we have to use desolder pump to suck the lead. Then use the solder wick to clean the tip of soldering iron.

Now i have done with our soldering process. This time, my partner Zaheerudin still work on the programming for our PIC16F877A. All the update is on his blog http://fyp4bmi.blogspot.com.So that all for this week. Hope you enjoy reading this blog and please leave your comments that can help me  to find what is my mistake if any.
