Assembled an ESR component tester by yourself

In this article we will learn the way on how we assemble a tester component or people call it an ESR meter. They name it an ESR meter because the tool that we are going to assemble is able to display the value of ESR (equivalent series resistance) on a capacitor which is very important for a technician. Component tester or ESR meter that we are going to assemble here are made based on PCB component tester sold by With the very small size of course the result will come up with a component tester or an ESR meter …

How to Solder a SMD Component

Soldering? Generally using what? Of course using a solder, the most common and many people using it. Actually, in fact there are several conditions that require us to use other type of solder to assembly electronic components. Just like laptop or hand phone mechanics that need other type of solder to help their job. That is a blower, there is also an infrared solder. This type of solder is required for servicing a laptop or hand phone, used for installing and uninstalling the BGA component, the component that its pad solder is at the bottom of the component, so that …
