INTRODUCTION

This is the time when i done with PCB. To install all components in PCB i need to make a holes first but not all components have same leg in size. thus i need use a differences size of driller to make holes then soldering

MAKING HOLE AND SOLDERING THE COMPONENTS

1.0 DRILLING PCB  

To complete the PCB production, fix the board to a piece of wood, drill holes (holes should be at least 0.1 mm bigger than pins/wires), and cut the board to the desired size. i also used varnish spray as a finishing coat. 

the driller is using 12 v supply, 350-550 mA where its using adapter AC / DC

the size of every holes are not same with each others as the components are not same. thus every size of holes i drilled depends on the components leg size

2.0 SOLDERING

before do the soldering, i recheck all connection with multimeter to see either the connection line is connected or not. then i solder all of components as the task (refer to of the project). the soldering tips applied as i want the best result of my project.
