BIOS (basic input/output system) is the program a personal computer's microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer's operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.
A CPU benchmark (CPU benchmarking) is a series of tests designed to measure the performance of a computer or device CPU (or soc). A set of standards, or baseline measurements are used to compare the performance of different systems, using the same methods and circumstances.
LAPTOP BATTERY TESTER
Charging: Two channels can work independently and serve two intelligent batteries separately. Active, pre-charge, constant current and constant voltage are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don't happen to every batteries.

An oscilloscope enables waveforms to be seen and in this way makes it very much easier to see any problems occurring in an electronics circuit. Sometimes the name cathode-ray oscilloscope, or CRO is used. The reason for this is that cathode ray tubes (CRT) used to be used to enable the waveforms to be displayed.
Nowadays, LCDS, or plasma displays are used as they are smaller, and more convenient to use, especially as they do not require the very high voltages of the old crts.
A Ball Grid Array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package.
HOT AIR GUN
Electric heat guns have now largely replaced the 'old fashion' paraffin and bottled gas blowlamps for stripping paint on timber. The hot air flow of a heat gun is less dangerous than a naked flame but it can still cause highly flammable items to catch fire, crack glass and injury if directed onto skin. One great advantage is that the heat is almost instantaneous so the heat gun can be switched off during pauses in the work while the flame blowlamps have the inconvenience of needing to be relit if the flame is extinguished.
The electric heat guns now available are lightweight, easy-to-use tools which make it far less likely to scorch wood or crack glass when used correctly to strip paint.
Industrial fans and blowers are machines whose primary function is to provide and accommodate a large flow of air or gas to various parts of a building or other structures. This is achieved by rotating a number of blades, connected to a hub and shaft, and driven by a motor or turbine.
A soldering iron is a hand tool used in soldering. It supplies heat to melt solder so that it can flow into the joint between two work pieces. A soldering iron is composed of a heated metal tip and an insulated handle.
CCTV (Closed-Circuit Television)
CCTV (Closed-Circuit Television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV relies on strategic placement of cameras and private observation of the camera's input on monitors. ... Maintaining perimeter security.
A Digital Video Recorder (DVR) is an electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device.
A Network Video Recorder (NVR) is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory card or other mass storage device. An NVR contains no dedicated video capture hardware.
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. A data packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.
Stand is used to hold the PCB of a mobile phone while soldering or repairing. It holds the PCB very strongly and doesn’t allows it to move thus helping in repairing. Again, it is important and wise to select a good quality PCB holder rather than a cheaper and inexpensive one.
Solder wire is used to solder electronic components, IC's Or jumper. Composition of most solder wire is Tin / Lead in the ratio 60:40 or 63:37. Since the introduction of ROHS (Restriction of Hazardous Substances) from electronics, more and more companies are using lead-free solder. Lead-free solder wire is available in many compositions but the most common composition is Tin / Silver / Copper in the Ratio 96.5:3.0:0.5. Solder wire is available in different diameters such 2.0mm, 1.5mm, 1.0mm, 0.5mm, 0.2mm etc. For mobile phone repairing 0.5mm solder wire is best suitable. Kester is a world renowned manufacturer and supplier of solder wire and other soldering material.
THINNER OR PCB CLEANER
Thinner or PCB cleaner is used to clean the PCB of a mobile phone. The most common PCB cleaner used in mobile phone repairing is IPA or Isopropyl Alcohol. It is important to buy only good quality PCB cleaner as poor quality PCB cleaners can damage the board.
This is a thin laminated or coated copper wire used to jumper from one point to another on the track of a mobile phone while repairing. Most people doing the work of mobile repairing do jumper to solve many problems.
This is used to remove lamination from jumper wire. It can also be used for several other purposes.
POINT CUTTER It is used for cutting.
NOSE CUTTER It is used for cutting.
It is used to remove and tighten screws while assembling and dissembling a mobile phone. Precision screwdrivers of sizes T4, T5, T6 and forehead are good for most mobile repairing job.
These are needed to hold electronic components, ics, jumper wire etc while soldering and Desoldering.
These are used for cleaning the PCB of a mobile phone while repairing. It is important to buy only ESD-Safe cleaning brushes.
