Steps To Follow In Order To Find The Electronic Components Supplier

Selecting the right electronic supplier is the foremost step to ensure that you get quality electronic components. Whether it is new or obsolete and discontinued electronic components, if you want to buy any component when the need arises, you should look for the suppliers that supply hard to find, long lead time electronic components.

Always be careful and never purchase counterfeit parts or any of the damaged components. For the long term sustenance of the components, it is necessary to go for the right vendor. Doing proper research about the technical knowledge, marketing, customer support system, product range and other factors should be considered before choosing your dealer.

The suppliers you decide on should be authenticated and certified to do this business. Fraudulent firms providing counterfeit products should be avoided. If the products turned out to be fake rather than genuine original products could create some serious problems later.

Next thing to keep in mind is the timely delivery. If the product arrives too late then it's of no use. So the suppliers which can provide you products under the agreed time have the potential to make the successful business partnership.

And the price of the components should be the standard ongoing market price. However if you are getting exceptional services with extra bucks and if they are within your budget, then paying more is totally worth it.

Next one is the component testing. The components have to be checked time to time for defects and flaws. All these steps are crucial to find the suitable components supplier. This way you don't have to worry about fake or defective pieces reaching you.

And the parts which have now become out of date can be difficult to find. So the dealer which can provide you any component in timely manner is the one you should prioritize even if you have to pay extra than the normal fees charged.

How to Test the Basic Electronic Components?

PCB, printed circuit board, is composed of variety of basic electronic components including capacitors, resistors, diodes, transistors and fuses. If any one of the component fails, the PCB may fail. Therefore, after buying electronic component from distributor, it’s important that each component be monitored and tested so that the performance is not hindered.

You may need a test gear for testing the components. The most suitable item of test gear is Multimeter. This can test almost 90% of all components.

Before you measure any component, you need to know what you are checking. If you are measuring voltage, select the AC range or DC range. If you are measuring resistance, select the Ohms range (x1 to x10k). If you are measuring current, select the appropriate current range DCmA 0.5mA to500mA.

You must select a voltage or current range that is higher than the maximum expected value, to avoid the needle swinging across the scale and hitting the end stop.

Reading 4-Band Resistors

Commonly the resistor has 4 bands and is called 10% resistor. Before testing a resistor, find the accurate reading for the specific resistor. Then connect the multimeter leads to specific resistor and then run a test. If the results are too high, this may indicate an open resistor or a resistor that has acquired a higher value.

Testing a Capacitor

One end of the capacitor should be removed from the circuit. The power supply to the capacitor should match the range of the capacitor so as not to overload the device. The possible outcomes can be the capacitor can short the meter that will reflect the output voltage of the power supply; if the capacitor is leaking, the meter reading will fluctuate, if the meter registers no jump at all, the capacitance is too low to register a result.

Testing a Diode

Disconnect one end of the diode from the circuit board and use an analog meter, identify the red and black meter probes. Set the meter between 1 and 10 ohms, connect the black probe to the cathode and the red probe to the anode. If the meter registers two readings, the diode may be leaky. If the meter registers some resistance, then the diode is forward biased.

To get the maximum performance, proper testing procedure should be followed along with the precautions.

Things You Need To Know About Active and Passive Components

The electrical components are of two types - active and passive. The component which is used for power gain is active component and the one which uses the energy is passive component. Electronic circuits needs active components in order to function.

Components that utilize the power instead of delivering it is passive component. They depend on active components to function as they cannot control the current flow on their own. Passive components can multiply the signal by values that are less than one.

They can however reserve energy for the later use when there is a need to release energy  and are used to filter the signals and have the ability to oscillate them. Some of the Active components are as follows:

Diodes: It is a pn junction that conducts the current in single direction only. They require some energy source to perform operation. If the reverse voltage is high enough then they can also create a reverse current.

BJT Transistors: These are Bipolar Junction Transistors. They have two pn junctions and operate in four modes. Both holes and electrons are carriers in the transistor structure.

Digital integrated circuits: These integrated circuits have digital pluses and could be multi-million component computer to simple counters.

Displays: They are used to display the output to the user.

Passive components do not require external energy, some of the passive components are as follows:

Resistors: They are used to create resistance in the current flow.

Potentiometer: They are used to create variable resistance which can be changed with a tap.

Capacitors: The energy can be stored in the electric field through capacitors.

Connectors: To connect different parts of the circuit for the signals, we use connectors.

Relay: It is a switch which can be turned on and off using an electromagnet.

If you want to buy passive components, consults the dealers in your area which can provide you high end products that satisfy your requirements.

Types of Electronic Passive Components That Are Used

Electronic components are categorized in two categories active and passive components. Components which make the energy in the form of voltage are called active components and components which stores the energy in the form of voltage are called passive components.

Electrical Passive Components in an electrical system do not need any electrical power in order to operate. They are incapable of power gain. Some of the different sorts of components include fixed resistors, capacitors, surge protection components and inductors.

These kinds of components do not amplify the power of the signal. Though, it is possible for the passive components to boost voltage or current through an LC circuit that stores electrical energy. Generally, there are two type of passive components - lossless and dissipative.

Dissipative —These components are not capable of absorbing power from external circuits over time.

Lossless — these components do not have a net power flow into the component. Some of the common examples include inductors, oscillators, capacitors and transformers.

What Types of Passive Components Exist?

The gamut of passive components when it comes to their function and form in different devices, and there are many types out there:

Capacitors — a capacitor is a component that can actually accumulate and hold a charge in a way that is similar to the work of a battery. It can hold the charge even in the absence of the voltage.

Fixed Resistors — Fixed resistor is a part of an electrical circuit. The resistor helps to reduce the flow of current through the circuit. Resistors come in two different types -  variable and fixed. The fixed resistors have a predetermined value and are unable to change.

Inductors — Inductors store energy within their magnetic field and provide the circuit with that energy when it needs it. They have a cylindrical core having a number of coils of conducting wire around it.

Cost Management While Choosing Electronic Component Supplier

The suppliers you choose in electronics manufacturing decides the success and profitability of your product. The reliability and quality of a product depends upon the electronic components suppliers. The important factors to keep in mind while choosing the supplier are reliability and high-quality of the products while managing operating costs are as follows:

Factors Influencing Cost 

A host of factors drive your cost up or down depending on how well you structure your agreement with your supplier. Depending on the period of time your products  are being covered and the scope of supplier’s warranty, the cost structure can vary. Tariffs, transportation, duties, engineering services, prototyping costs, and authorization services for returning materials are among critical cost factors that are mostly overlooked.

Lack of Visibility in Price Structure

Some manufacturers are hesitant in providing breakdown of price in a detailed way that specifies test, labour, manufacturing overhead, material cost, labour, cost of acquisition, and profit or gross margin. But without clarity in cost breakdown, how can you know about the cost improvement opportunities you could get in the future or the kind of assumptions used in product quoting.

Ambiguity in Details Regarding Supply Chain Model

It is always better to have discussion beforehand whether all transportation costs such as duties,  taxes, and freight, taxes included, or will they be separately invoiced? All of these can have a perceptible impact on your product cost.

Lack of Attention to Non-price Issues

The cost structure for repairing products that are not in warranty, the inventory for warranty repairs under different cost structure and different locality and how do quality associated metrics like per part million failure rates and yield play into the total price.

If you are looking for electronic component suppliers then classify the supplier based on your specific requirements and supplier ratings to ensure that you get certifiable, high quality and OEM-traceable products.

Challenges Faced By Supply Chain Managers

Obsolete components are the hard to find electronic components in the regular market. With technological advancements everyday, it is becoming challenging to find obsolete components. Supply chains are not left unhinged under this scenario, they go through several challenging phases and deal with real issues everyday. Some of the challenges being faced by supply chain managers today have been listed below:

Inventory Management:

Inventory is no longer associated with just box counting alone. Today, the warehousing industry is one of the most challenging phenomenon and it must work in synch with other company departments to exceed client expectations. In order to cope up with timely delivery of large orders, the companies need to stock enough inventory to avoid any delays in orders or else the profits might be affected.

Supplier Management:

Like with great power comes great responsibility, similarly with inventory comes suppliers and it can be a daunting task to manage them. Supply chain managers have to be absolutely aware when they need to procure one item or more from a supplier. They also have to manage the suppliers in an adequate manner to maintain their services with consistency and reliability at the right prices.

Quality Control:

Ever since globalization, managers often face challenges in the form of maintaining quality control of the products manufactured overseas, which are not in synch with prescribed standards of their country. Thus, supply chain managers also have to ensure that different products they procure are of standardized quality and can fit well in the supply chain. Failing to do so can affect the cash flow adversely.

Risk Management:

Supply chain managers have to take care of supplier issues in such a way that it doesn’t affect the company adversely. They often have different vendors around the globe to mitigate the risk of losing supply from a single supplier in case of any calamities like earthquake etc. They need to have proper backup plans to maintain their company’s profits at all times.

Hence, a supply chain manager’s job isn’t easy. They have to factor in all risks and possibilities across the supply chain at all times. SCM is a silent process but has to run smoothly for a company to function properly.

Emerging Challenges In Electronics Industry

The advancement in electronics industry is often startling and there has been a major paradigm shift over the past few decades. The manufacturing division of electronic components has direct impact on the electronic component distributors in the market.

The electronic companies have to be on their toes at all time and change swiftly with time to meet the emerging challenges in the market. Let us have a look on some challenges being faced by the electronics industry and distributors alike:

Reduced Operating Margins

Constant innovations and global competition have driven the prices down. In such a scenario, the companies need to be cost-efficient in all perspective to maintain their profits.

Complicated Supply Chains Globally

Almost every company has to play their cards well and stay well as per international standards while properly allocating both internal and external resources. Multiple issues like compliance and traceability are putting additional operational burdens on the companies. Sometimes the components and additional subcomponents travel across three continents or more before reaching their final destination and then the final user.

Managing Warranty and Service

In order to leverage the supply chain across the globe, a lot more focus is laid on managing the quality. Superior quality and traceable systems improve the warranty reserve and service hours in the post production department.

Diminishing Product Life cycles

Consumer preferences can change instantly and as a result all EMS companies and other contract based manufacturers must be equipped with a New Product Introduction (NPI) process. Effective communication between manufacturing, sales and R&D are integral for timely products launches with the right volume and targets.

Uncertainty In  Demand

Volatile economics and cyclic demands can create a lot of fluctuation in production. It is important to have lean capabilities and keep a demand aligned inventory.

The increasing standards and regulations are driving companies to account more for CSR- Corporate Social Responsibility. Since E-Waste is one of the hot topics these days and a lot of stress is being laid saving the environment, the companies must think of complete lifecycle of products while making decisions.
