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 Technology.

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, they attract each other. When …

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 conclude and define electric current …

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 called orbits. Protons are …

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 the electron.

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 are brought together either intentionally …

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 or rotation of turbines. These …

10 Easy Ways on How to Slash Electricity Power Utility Bill

People around the world are bothered about increasing energy costs and rising home electric bills. The home electric meter is also moving fast because of more and more use of home appliances and gadgets. The electric bill gets higher during summer with heavy cooling demands. People want to know how to save energy at home and office and slash electricity …

Lead-Free (Pb-Free) Solder and Composition

Lead-Free Solder: Solder with NO Lead (Pb). Lead-Free is taking rapid momentum around the world after the EU (European Union) Directives to wipe off lead (Poison) from electronic soldering considering its health and environmental effects

RoHS: Restriction of Hazardous Substances [ lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE).]…

All about Semiconductor

A semiconductor can be defined as a substance with properties of a conductor and insulator (electricity).

A semiconductor can conduct electricity under certain circumstances but not always. This property of a semiconductor makes it a good medium to use electricity in a controlled manner as and where required.

Conductance of a semiconductor depends on several factors such as …

Top 10 Consumer Electronics Companies in the World

Consumer electronics has become a part of our everyday life. Electronics products and gadgets in the group of consumer electronics include all such electronic equipments that we use in our everyday life – entertainment, communication and other home and office electronic equipments and gadgets. Personal computers, laptops , television, telephones, mobile cell phones, MP3 players, MP4 players, audio …

How Electronic / Electrical Circuit Works

Electric charge is nothing but flow of electrons from one object to another. We all know that an atom is made up of electrons, protons and neutrons (look at the diagram on the right that explains the structure of an atom).

Electrons are negatively charged and protons are positively charged while neutrons are neutrally charged. At the same time the …

Ball Grid Array (BGA) Package

Ball Grid Array or BGA is a surface-mount package (with no leads) utilizing an array of metal spheres (solder balls) for electrical interconnection. BGA solder balls are attached to a laminated substrate at the bottom of the package. The die of the BGA is connected to the substrate by wire bonding or flip-chip technology. The BGA substrate has internal conductive …

SMT Troubleshooting (SMT / SMD Problem and Solution)

SMT (Surface Mount Technology), like other SMD Soldering and PCB assembly technology is not ZERO-Defect soldering process. There will always be some or the other defect in any Electronics PCB assembly in both Thru-Hole and SMT.

Here I will discuss some of the most common faults and causes of SMT defects and possible solution and troubleshooting.
