Pin Hole & Blow Hole Soldering Defects and Remedies on PCB Solder Joint

Pin hole or blow hole defects are the same problem caused by the printed board outgassing during wave soldering. Pin hole and blow hole formation during wave soldering is generally associated with thickness of copper plating. Moisture in the board escapes through either thin copper plating or voids in the plating. The plating in the …

Types of Electric Current

Electrical current is the flow of charged particles. It is similar to flow of water molecules in a river. Electric current is of two types:

  1. Direct Current (DC)
  2. Alternative Current (AC)

Direct Current: (DC):

In this type of electric current, direction is always same. The electric current generated from a cell or battery is DC. …

Basic Electronics Definition | What is Electronics

Electronics is science of controlled activities or movement of free electrons present in Atom of a matter.
The first electronic component every made in 1906 was triod or triode.

Triode - A triode is an electronic amplification device having three active electrodes.

Electronics is used in factories, at home, in medical field, defense etc.

Electronic Components:

All electronic components are divided into two categories:

  • Active Devices
  • Passive

Soldering in Electronics – Hand Soldering | Automated Soldering | SMT Soldering | BGA Soldering | All Process of Soldering in Electronics

Soldering in electronics is all about joining electronic components to the PCB by hand using soldering station or soldering iron, or wave soldering using wave soldering machine or reflow soldering using reflow machine.  Soldering can be either hand soldering or automated soldering. It can also be either thru-hole soldering or SMT Soldering using Surface Mount …

SMT Book – Surface Mount Technology Book PDF

Good SMT Book (Surface Mount Technology) is rare to find. Here I explain about one and only available best SMT Book that comprehensively covers this field of electronics.

Potential Difference

What is Potential Difference?

Potential difference can be simply defined as the difference of electrical potential between two points. When two positive charges when brought close to each other, they repel. When two negative charges are brought close to each other, they also repel. But when a positive and a negative charge brought close together, …

Electric Current

What is Electric Current?

Electric current is the flow of electric charge (charged particles) through a conductor with respect to time. The process is similar to flowing of a river in one direction. Electric current is measured by the number of “free electrons” passing a particular point in a circuit per second. So we can …

Structure of an Atom

During our school days, we all studied in science that atoms are made up of 3 particles – electrons, protons, and neutrons. The arrangement of electrons and protons are different in different elements. We also learnt that electrons are negatively charged (-) and revolve around the nucleus of the atom in concentric paths …

Electronics History Timeline (600 BC to 2007)

Electronics is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons. This control of electrons is accomplished by devices that resist, carry, select, steer, switch, store, manipulate, and exploit …

ESD Safe – Electrostatic Discharge Safety

What is ESD?

ESD stands for electrostatic discharge. ESD can be defined as transfer of electric charge between two different objects charged to different electric potentials. This happens when the two object are brought in contact with each other. Electrostatic Discharge can also happen when two objects with different electric potentials due to static induction …

How is Electricity Generated, Transmitted and Distributed?

Electricity generation, transmission and distribution is a complex engineering process. The process requires huge investment and skilled manpower.

The basics of generating electricity remains the same in all forms of electricity such as hydroelectricity, electricity generated using coal, nuclear electricity, renewable energy sources etc.

How is Electricity Generated?

Electricity is generated or produced by turning …
