Whether it is making calls, sending text messages, surfing the Internet, playing games, taking photos and videos, the reception, processing and execution of each instruction are inseparable from the operation of the motherboard. If the mobile phone is compared to a person, then the motherboard is the core organ of the person, and its importance is self-evident. Once it is "sick" or "strikes", the mobile phone will become a lifeless "brick".
Soldering and Desoldering Tools:
Soldering Iron: A High-quality Soldering Iron is essential. Temperature-controlled soldering irons are preferred as they allow you to adjust the heat according to the soldering requirements. For example, a soldering iron with a temperature range from 200 - 450 degrees Celsius can be used for different soldering tasks such as soldering small components like resistors and capacitors (lower temperature) and soldering larger connectors (higher temperature).
Soldering Station: A soldering station usually includes a soldering iron and a temperature control unit. It provides a more stable power supply and accurate temperature adjustment, which is crucial for precise soldering work. Some Advanced Soldering Stations also come with additional features like a soldering iron holder and a sponge for cleaning the soldering iron tip.
Solder Wire: Solder wire is used to create the electrical connections between components. There are different types of solder wire, such as Lead-free Solder Wire and traditional lead-containing solder. Lead-free solder is more environmentally friendly and is widely used nowadays. The diameter of the solder wire also varies, and a 0.6 - 0.8mm diameter is commonly used for mobile phone motherboard repair as it allows for precise application of solder.
Solder Sucker: A solder sucker, also known as a desoldering pump, is used to remove old solder from components or pads. It works by creating a vacuum when the plunger is depressed and then released, sucking up the molten solder. This is useful when you need to remove a damaged or faulty component from the motherboard.
Desoldering Wick: Desoldering wick, also called solder braid, is a copper-plated wire that absorbs molten solder. You place the desoldering wick on the solder joint, heat it with a soldering iron, and the solder is drawn into the wick. It is a good alternative or complementary tool to the solder sucker, especially for fine - pitched components.
Precision Tools:
Tweezers: Precision tweezers are used to handle small components such as chips, resistors, and capacitors. Anti - static tweezers are recommended to prevent damage to sensitive components caused by electrostatic discharge. There are different types of tweezers, such as straight - tipped tweezers and angled - tipped tweezers. Angled-tipped tweezers are useful for reaching components in tight spaces.
Micro-Screwdrivers: Mobile phone motherboards are often held in place with small screws. A set of micro-screwdrivers with different sizes and tip shapes (such as Phillips and flat - head) is necessary to open the phone case and access the motherboard. Some Micro-screwdriver Sets also come with magnetic tips, which can prevent screws from getting lost.
Inspection and Testing Tools
Multimeter: A multimeter is used to test the electrical properties of components and circuits. You can use it to measure resistance, voltage, and current. For example, you can use a multimeter to check if a component is short - circuited or if the power supply to a particular part of the motherboard is correct. Digital Multimeters are more accurate and easier to use than analog ones.
Magnifying Glass or Microscope: Given the small size of components on a mobile phone motherboard, a magnifying glass or a microscope is essential for close - up inspection. A Stereo Microscope with magnification capabilities ranging from 10x - 40x can help you identify tiny cracks, damaged solder joints, or other physical defects on the components.
Cleaning Tools:
Brushes: Soft-bristled brushes, such as nylon brushes, are used to clean the motherboard surface and remove dust, debris, and flux residue. A small, precision brush can be used to clean around components without causing damage.
Cleaning Solutions: Isopropyl alcohol is a common cleaning solution used to clean the motherboard. It can dissolve flux and other contaminants. You can apply it with a brush or a cotton swab to carefully clean the soldering areas and components.
