BATTERY CONTACT | EQUIP TEST

 

Importance of Battery Contact

 

Battery contact is a metal part that connects the battery to an electronic component or device. There are two components involved, a battery spring and a contact. It is made of various metals and has a specific shape and size that is determined by the type of battery. A typical battery has two connectors for both positive and negative terminals. To have a power supply in electronic components both terminals need to be in contact with a battery. This component is developed to be the most important component of any electronic circuit.

 

Depending on the battery type, these contacts come in a variety of shapes and sizes. The circuit couldn’t connect to a battery if there was no contact present. 

 

Construction of a battery contact depends upon various criteria such as: 

·         Type of material used to make a battery

·         The shape needs to be proportionate to the battery

·         How much power or load would provide to that electronics component

·         Must be capable to hold the battery as well as resist towards the load

·         The position of contact then should go for the manufacturing process

 

Choosing the right metal for the contact is irrespective of battery type. They are made with specific metals like Nickel-plated, Steels, Beryllium Copper, Gold, platinum, phosphor bronze, brass, Tin plating, Copper plating, Zinc plating. 

 

Types of contact:

·         Surface-mounted

·         Cylindrical and spring

·         PC battery

·         Enclosure

 

Surface Mounted batterycontact is used in the small-scale circuits preferred to design PCB circuits. Cylindrical and spring are the best and cheapest among others due to their designed battery space. Precautions must be taken when cleaning these electrical components, as failure to do so can result in burns from corrosion.

 

The design of a battery’s contact is determined by two factors: fixed or flexible structured, or a combination of both. This concept is usually taken from the prototype stage to the manufacturing stage by the company that manufactures batterycontact. They accomplish this by employing sophisticated techniques such as hydraulic presses, power presses, four-slide, and multi-slide equipment. Once a concept has been approved, they create an engineering prototype; the project can begin right away.

                        BURN IN TEST | EQUIP TEST

What Is Burn-in Test?

 

The burn-in test is a test of electrical and thermal that stress in any semiconductor device for detecting early failure. There are three types of semiconductors failure such as early failure, random failure, or wear-out failure. This test has two types static burn-in testing and dynamic burn-in testing. Ages of practice those discover excellent techniques to predict the system’s validity. These techniques are determined to protect systems from damages and failures. 

 

Burn-in test is a technique to finds the fault in a semiconductor device or a failure before getting assembled in any system. This test forces every device to reach its maximum limit till it becomes a failure. The whole process is taken under the expert’s supervision also the capacity of the device is analyzed. It improves the reliability of the component to be used in a system. The Burn-in test is critical in removing defective parts from the production line after they have been manufactured.

 

Types of Burn test failures,

 

• Early failure can be found at the initial stages of any semiconductor device during operation. It helps in analyzing the early failure rate.
• Random failure can be found over a long period where the failure rate is constant. It helps in analyzing uncertain failures. 
• Wear-out seems to occur at the end of the production line testing. The devices frequently undergo this failure as compare to Early and Random failure rates.

 

A Burn-in test is a process for detecting and discarding defective solid-state electronic components before they are sold or incorporated into electronic devices. 

 

Equip-Test probes like High-Current probes were designed to reach high pointing accuracy and lifelong durability. High-Current probes are categories under their load capacity such as high-current probes up to 20 amperes, two types of high-current probes up to 30 amperes, and two probes up to 50 amperes. This test is one of the applications of these test probes to prove their reliability. The high-current probe has its own unique designer tip. Each and every test probe was designed to be more productive and easy to handle.

                               RF TESTING | EQUIP TEST

                          How useful RF Testing is?

In this highly tech-savvy world, we are more or less dealing with radio waves-aided activities daily whether it’s directly or indirectly. To keep airwave highways free from congestion, Radiofrequencytesting plays a key role. This is why proper testing and setting up of radio frequencies are very important. Radio frequency (RF) is the oscillation rate of electromagnetic radiation spectrum or electromagnetic radio waves. In simpler terms, it is the vibration that we use to tune for a specific radio broadcast.

 

RF testing enhances the functionality and performance of radio and telecommunications equipment so that the devices won’t overlap with other users’ radio frequency spectrum and go on verifying whether the radio equipment is using the radio spectrum effectively or not. Wi-Fi, GPS, Cellular devices, PMR radio radiofrequency testing. Compliance with frequency standards is governed and approved concerning market regulations.  Therefore, proper RF testing carries so much importance these days.

What is Wi-Fi?

Wi-Fi stands for 'wireless fidelity.'  It means a computer can access the Internet without wires or cables. Wi-Fi is a wireless connection allowing the users to avail the Internet without being connected to a cable. Radio signals are transmitted from one system or Bluetooth device to a wireless router or wireless local area network (WLAN). Laptop, PCs and Personal Digital Assistants (PDAs) utilize Wi-Fi technology.

 

All You Need to Know about Kelvin Probe

 

Kelvinprobe is test equipment that measures the functional difference between the tip and sample when achieving the thermal equilibrium state, and also marks the electric potential difference in its work and external or internal applied voltage during the experiment. It is a non-contact, non-destructive experimental device used to investigate the properties of materials. It is a highly sensitive instrument used to analyze changes in the contact potential difference between a metal and a given sample.

 

It has been assumed that the given materials Fermi level is unchanged during the experiment; the changes in the Kelvin probe junction contact potential differential can then be attributed entirely to changes at the sample surface. Some terms may be expressed differently depending on your knowledge: Fermi-level, surface potential, surface diode, work function, corrosion potential, contact potential, and the other terms are used in this article. 

 

Experimentally we can say that Kelvin Probe needs to be positioned, such a way that its tip touches the reference material so that it measures the Single Electron Transistor Device. Based on this experiment, the Probe has been converted into a highly sensitive tool for analyzing the surface properties of materials. Metals, alloys, semiconductors, and even insulators, are among the materials to which they can be applied.

 

The Kelvin test has two types;

• 2-wire measurements
• 4 -wire measurements 

 

Connecting one lead to one end of the trace and the other end to the other end completes the circuit and allows current to flow through the metal when measuring resistance with an ohmmeter. Once the current is flowing, the resistance will be calculated using the ohms law. The 4-wire probe was originated to improve the overall quality of the products.

 

Equip-Test Probes have a testing kit that includes a Kelvinprobe, which we knew as the heart of any Test fixture. This probe offers high-performance with the best quality and values. It also provides the best possible available solution for everyone concerned to ensure the ROI for our customers.
