Logic board iphone 7

Types of Logic Board iPhone 7

The iPhone 7 logic board comes in two primary types based on storage capacity: the 32GB logic board and the 128GB/256GB logic board.

Every iPhone 7 is designed with a respective logic board that is unique to the device. The logic board is sometimes referred to as the main board of the iPhone. It is the primary circuit board, also known as the motherboard. The logic board seamlessly integrates all the essential components and features required for the iPhone to function. This includes the CPU, RAM, storage, and various other connectors and chips that support the device's capabilities. Every iPhone 7 has a logic board uniquely designed to match the model. The model signifies compatibility with a particular case and set of components. This means that using a different iPhone 7 logic board on the phone may result in incompatibility upon powering it on. The process of swapping these boards is very tedious and requires a lot of expertise and delicate handling of the components. First, the phone has to be powered down before removing the screen. Adhesive holds the screen to the frame of the phone and has to be cut off using a heated blade. After the screen, the battery has to be taken off too, using a suction cup and the same heated blade. Upon accessing the logic board, all screws have to be removed using the very small screwdriver set. Once the board is removed, the SIM tray and any attached assembly can be inserted into the other board before reassembling the phone.

The 32GB logic board is meant for basic smartphone tasks like calling, texting, browsing, and using light apps. On the other hand, the 128GB/256GB logic board can store large photos, download movies and games without worrying about running out of space. Most of the apps in the app store will function normally and faster since the user will have access to 4GB RAM on the iPhone 7 logic board. More storage also enhances a phone's resale value, and users are less likely to delete apps or files to create space. This logic board also comes with upgraded iOS versions.

Another classification of iPhone 7 logic boards is unlocked boards and locked boards. Unlocked boards are those that weren't tied to any specific carrier network when they were first sold. They can be used with any network provider worldwide. Locked boards are originally sold locked to a specific carrier network and can only be used under that network. Sometimes, locked boards can be unlocked. Users will have to check with the network provider, as some companies allow unlocking after meeting certain conditions. There's also a distinction between original and aftermarket iPhone 7 logic boards. Original boards were manufactured by Apple for the iPhone 7 device, while aftermarket boards were made by a third-party supplier. Some aftermarket boards are compatible with the phone, but their quality may vary.

Function and feature of logic board iPhone 7

The iPhone 7 logic board is a small circuit board containing several components that help the phone function well. It is compact, measuring around 138mm x 67mm x 1mm. That way, it fits snugly inside the iPhone 7 frame. This keeps the phone lightweight and slim. The board has numerous soldered parts. They include the CPU, NAND flash memory, and various capacitors and connectors. The board is well laid out. All parts connect through circuits so that signals and power can move between them.

• Key Functions

  The logic board has several important functions. It controls the phone's processing, data storage, and connectivity. The iPhone 7 uses a powerful A10 Fusion CPU and an embedded controller on the logic board. Together, they determine the phone's speed, performance, and efficiency. They also execute instructions and run programs. There is flash memory storage, or RAM, on the logic board. It holds the operating system, apps, and user files. This coherent design means everything works smoothly to provide a good user experience.

• Compatible Parts

  When repairing or replacing the logic board, using compatible parts is essential. Compatible connectors, screws, and adhesive allow seamless reassembly. They ensure the new or repaired board functions as intended. Features such as the board's state of oxidation can also signal compatibility. Parts from a board with similar oxidation levels to the one being replaced are more likely to work together without issues. They reduce the risk of connection failures and other functionality problems.

• Repair and Replacement

  Replacing a broken logic board is usually only sometimes successful, depending on the damage. Replacing the board can fix hardware issues sometimes. But since each board is uniquely programmed to the phone it was initially installed in, other functions like Touch ID may fail even after replacing the logic board. This makes regular phone backups very important. Data is not permanently lost even if the logic board gets damaged beyond repair.

Applications of Logic Board iPhone 7

There are many ways the iPhone 7 logic board can be utilized. Here are some of them:

• Phone Repair Shops

  Them buying the logic boards can reduce or increase the efficiency of repairs. If a repair shop buys the whole logic board, it can replace many damaged or malfunctioning phones and save the time spent looking for individual components to repair a phone. Buying in bulk can also make them save costs, thus increasing profit margins.

• Electronic Waste Recycling

  Logic boards hold different metals, such as copper, that can be recycled. Buying these logic boards in large quantities from various suppliers can help them collect more of these boards and the metals that can be recycled and used to create new products. This is not only beneficial for their business but also helps to reduce electronic waste.

• Refurbishing

  Some businesses specialize in refurbishing used electronics and selling them as secondhand phones. The available logic boards can be used to repair and upgrade those phones. These businesses can then sell the refurbished phones as budget-friendly options for customers looking for affordable alternatives to new phones.

• Parts Harvesting

  For businesses that have repair stores, buying iPhone 7 logic boards in bulk can be helpful in that they can use any part of the board to fix other working boards, thus reducing repair costs and time. They can also use the parts to upgrade existing phones in their inventory or to make custom electronics.

• Art and Craft Projects

  Some people enjoy using electronic materials to create art. Using the logic boards for art and craft projects can be a fun hobby for people who are interested in electronics and love creating art and want to turn their loose logic boards into creative art pieces.

How to choose logic board iPhone 7

Purchasing an iPhone 7 logic board is not as easy as it sounds. It needs a few considerations to make sure the selected one is in good condition and will work well. Here are a few tips to help buyers make the right decision.

• Condition

  The logic board is an important part of the iPhone 7. Without it, the phone is not usable. So, when purchasing the iPhone 7 motherboard, make sure it is in good condition. A good condition logic board will have no signs of damage or corrosion. Also, if possible, test the logic board. Ensure all the connectivity options are working properly.

• Refurbished or Used

  When it comes to iPhone 7 logic boards, buyers have two options to choose from. They can either purchase refurbished ones or used.

They can have major damages or become faulty after usage. However, they are more affordable than refurbished ones. Depending on the budget and target customers, buyers can choose which one will work well.

• Part Compatibility

  It is important to know that there are two types of iPhone 7. This simply tells us that the logic boards for both models are not the same. The boards have different part numbers. So, to avoid mix-ups, referring to the compatibility model is highly recommended. Also, make sure the motherboard is compatible with other components and accessories.

• Supplier Reputation and Warranty

  When it comes to purchasing electronic components, checking the supplier's reputation is important. Check reviews from previous customers to see how satisfied they are with the purchase. Also, check if the supplier provides warranties on the parts they sell. This shows that the supplier is confident in the quality of the parts he sells.

Q: Does an iPhone 7 hold water even with a changed back cover?

A: If the back cover is changed, the iPhone 7 won't be able to hold water again until a skilled person puts in a new water-seal ring. When the back cover is put on, a special rubber ring called a water-seal ring has to be added all around the edge so water stays out. This ring has to be put in right for the phone to resist water again. Without it, water can get inside through the gaps between the cover and the phone.
