Soldering Safety and Advice for Different Electronic Components

Soldering involves a process of joining two or more metals by melting and putting filler metal into the joint. Flux is used to facilitate the soldering process. For this purpose, filler materials are available in different alloys for various applications. In electronics assembly, the alloy of 63% tin and 37% lead is the most commonly used.

 When you buy electronic components for your device, you should know that the required soldering techniques because some products require special care while soldering. Here is the essential advice for different components.

  • Resistors: No special precautions.
  • Diodes: Must be connected the correct way round. a= anode, k= cathode
  • IC holders: Ensure that the notch is at the correct end.
  • Capacitors, electrolytic: These are marked + or – near one lead and must be soldered the correct way round.
  • ICs: Carefully insert the ICs the correct way round in their holders after the all soldering is complete.
  • Battery clips and buzzers and other parts with wires: Red (+) and black( –) wires must be connected in the  correct order.

Now when you know the precautions for different applications, have a look at the safety precautions you need to follow when soldering.

Soldering Safety Precautions

1.  Work in an environment that is well lit and ventilated.
2.  Unplug the soldering iron when it is unattended.
3.  Be careful to keep clothes, hair, power cables et., away from the soldering iron tip and the metal shaft.
5.  Always handle the iron by its plastic handle.
6.  Do not point the circuit towards yourself whilst trimming down component legs.

Soldering Iron

1.    Never touch the element of the soldering iron....400°C!
2.    Hold wires to be heated with tweezers or clamps.
3.    Keep the cleaning sponge wet during use.
4.    Do not put the soldering iron on the workbench, return the soldering iron to its stand when not in   use.
5.    Turn unit off and unplug when not in use.

These simple tips will prevent you and your device from any damage. Any error or mistake can cause serious damage.

Some of the Basic Electronic Components and their Functions

When building electronic circuits, we need to work with some of the basic electronic components including resistors, capacitors, transistors, integrated circuits etc. Some of these components are called active components because they are involved in transformation of the energy while other components, that only dissipate energy, are known as passive elements.
























Passive components are also called electrical elements. Some of the examples of passive components are:
Resistors:
A resistor is one of the basic components used in electronic circuits that resist the flow of current.
Capacitors:
Capacitor is the second most commonly used component in electronic circuits. It can temporarily store an electric charge. Capacitors come in different varieties, the two common types being ceramic disk and electrolytic. The amount of capacitance is usually measured in micro farads μF.
Diode:
Through diode, the current flows in only one direction. A diode has two terminals, called the anode and the cathode. Current will flow through the diode, when positive voltage is applied to the anode and negative voltage to the cathode. Current will now flow when these voltages are reversed.
Active components are those that have gain or directionality. Example: transistors, integrated circuits or ICs, logic gates. Active components can be further classified as semiconductor devices such as semiconductor diode, zener diode, Varactor diode etc.
Transistor:
A transistor has three terminals called base, collector and emitter. In this a voltage applied to one of the terminals can control current that flows across the other two terminals. The transistor is one of the most important devices in electronics.
Integrated circuit:
An integrated circuit consists of entire components including electronic circuit, complete with transistors, diodes, and other elements. Integrated circuits are the building blocks of modern electronic devices such as computers and cell phones.
All these components are essential for the building of any electronic components. If you want to buy any of these Electronic Components, you can contact a dealer who has a surplus distribution of electronic components.

3 Things To Check Before Choosing An Electronic Components Supplier

Electronic components are common in every field and place. But some industries heavily rely on these products for their daily operations. This is the reason why businesses look for a reliable supplier in market that they can trust for quality and authentic products. There are many suppliers in market who sell electronic components, but choosing one can be a bit difficult.

A variety of products, good reputation, good reviews and a long list of clients might confuse you, which one to choose. But, your decision should be based purely on your business requirements. This is why you need to check 3 things before you select a supplier.

Quality Assurance – Quality matters the most, which is why you need to make sure that the electronic component business you are choosing has a good quality assurance system in place. Before making a decision, ask for their certifications such as ERAI, ESD, ISO and so on.

Quality assurance will ensure that you purchase only authentic and tested electronic components avoiding fraudulent and counterfeit parts. So, if you can trust a supplier with the quality of products, then you are on the right path.

Shipping Information – This is the second thing that you need to know about a supplier. Gather as much information as you can about their shipping including rates, time, methods and more. Get to know if they process shipping within America or outside of the country (if you are ordering from another country).

Return Policy – Many business owners overlook the return policy, which is not a good idea. You should always have the knowledge of this policy as it may be useful in future. Choosing an electronic component supplier without reading the return policy might put you in a dilemma in case of faulty or damaged products, faded markings, damaged packaging etc.

Check the above mentioned three things before choosing an electronic components company for your business to ensure that you get what you paid for.

Points to Keep in Mind When Buying Obsolete Electronic Components

Electronic items are full of so many tiny components that there is a possibility that something will eventually break in them. Components in a large circuit board can face some serious problems every now or then, simply because there may be so many points of potential failure in the device.

Thus, it becomes a necessity to buy obsolete electronic components. Tiny components like resistors and capacitors are required in large supply. Even if one of them has a little flaw, it can cause critical problems within the entire device, often damaging other parts.

Here are some points to keep in mind when buying electronic components.

Procurement Supplier Selection
Procurement policies and the suppliers create an opportunity to significantly reduce the risk of forged parts.
  • Manufacturer, Franchised Distributor or Agent
In some cases, forged devices may have filled the production flow of a genuine manufacturer. The distributors who sell electronic components should detect the defects and fraudulent products.
  • Independent Distributors
To avoid fraud components, check for the most enlightened ID. IDEA (Independent Distributors of Electronics Association) has created specifications and guidance documents for its customers, in order to reduce the possibility of counterfeit and fake components flowing through their organisations.

Receiving, Inspecting and Examining products

  • Paperwork Considerations...
  • Look for whether the products look genuine?
  • Are there any changes being made to amend quantities, screening levels?
  • Are there any strange font sizes which do not line up with the general layout.
  • Packaging Considerations...
  • Is the packaging used correct to protect components from any further issue.
  • Humidity indicator cards and dry packaging is required if parts are moisture sensitive.
  • Are the dimensions of the package correct.
Look for companies that will give their employees opportunities that benefit both the company and the customers. Choose companies that sell excess electronic components and strive to be the best in their niche.
