Apple iPhone 7 - Specification - Disassembling procedure

1. Apple A10 Fusion processor with embedded M10 motion coprocessor
2. 32, 128, or 256 GB onboard storage capacity
3. 4.7-inch IPS multitouch Retina HD display with 1334 × 750 pixels (326 ppi)
4. 12 MP camera with f/1.8 aperture, optical image stabilization, and 5x digital zoom
5. 7 MP FaceTime HD camera with f/2.2 aperture and 1080p HD recording capability
6. Non-mechanical Touch ID home button driven by new Taptic Engine
7. 802.11a/b/g/n/ac Wi‑Fi + MIMO Bluetooth 4.2 + NFC
As you oppen iPhone 7,a few new additions on the surface:
A 1334-by-750, LED-backlit IPS display with a P3 color gamut and 25% higher brightness than that of the 6s.
An f/1.8, 12 MP camera with built-in optical image stabilization. Apple claims it's 60% faster and 30% more efficient than the previous generation.
A quad-LED True Tone flash that's 50% brighter than the iPhone 6s.
The iPhone 7 shares exact dimensions (138.3 mm × 67.1 mm × 7.1 mm) with its predecessor, the iPhone 6s-but has dropped a little weight, coming in at 138 grams compared to the 143 grams of the iPhone 6s.
Power off your iPhone before beginning disassembly.
Remove the two 3.6 mm Pentalobe screws next to the Lightning connector.
If the plastic depth gauge is attached at the center of the Sclack, remove it now -it's not needed for larger phones like the iPhone 7.
Close the handle on the Sclack, opening the suction cup jaws.
Place the bottom of your iPhone in between the suction cups.
Position the Sclack's upper suction cup against the display, near the home button.
Open the handles to close the jaws of the Sclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone
After briefly fighting through some sticky adhesives to open the case, you faced with another set of repair obstacles teeny tiny tri-point screws securing the cable bracket etc
With the front panel and strings of sticky glue out of the way, you can whip out our trusty spudger and disconnect the battery. Next, it's time to set our spudger to the task of popping off display connectors.
The iPhone 7 camera boasts a larger f/1.8 aperture, new 6-element lens and 12 MP sensor, four LEDs, and a flicker sensor that can sense flickering light and compensate for it in your photos and videos.
With the new camera out of the way, You can work our way deeper into the 7.
Next out: the audio baffle that thinks it's a headphone jack.
According to Apple, this plastic component is a barometric vent. With the added ingress protection afforded by the watertight seal, the iPhone uses this baffle to equalize the internal and atmospheric pressures in order to have an accurate altimeter.
This Taptic Engine takes advantage of its extra legroom, sizing up for its home button haptic duties.
With the path cleared, you can  use handy spudger to release the adhesive from beneath the battery.Wind up and peel out the three battery pull tabs.
The iPhone 7's power source. 
Actually, it's a relatively benign Lithium-ion battery. This 3.8 V, 1960 mAh battery is rated for a capacity of 7.45 Wh.
Apple claims that this upgraded cell will provide up to 14 hours of 3G talk time, 14 hours of Wi-Fi internet browsing, and 10 days of standby.
The iPhone 7 speaker ships with a leash stick-on Wi-Fi diversity antenna that connects to the logic board.
Waterproofing alert. The speaker's output duct fits over a rubber speaker grille gasket for an added layer of ingress protection.
This design is nigh identical to the one we unearthed in the iPhone 7 Plus a couple hours ago.
The duct also has a fine mesh in case the speaker grille doesn't do its water-blocking job.
The SIM eject tool ,pushes on a plastic pin, that pushes a metal pin, which in turn, ejects the SIM tray.
Apple added a rubber gasket around the SIM tray.
You can Now remove the logic board to take a closer look at some silicon.
If you look closely, you'll see minor differences in connector sizes and locations, post holes, and screw locations between the logic board of iphone 7 and 7 plus.

After logic board is out, its free to pick out the Lightning connector assembly.
Prying up the light adhesive went well, but our first tug was in vain. There are some extra screws in this port.
It seems like Apple has taken our warning to heart. Without a headphone jack to bear the burden of audio connections, this port will get a lot more wear, and it's been well reinforced.
Other denizens of the Lightning cable an antenna, two  microphones, two speaker grille plugs, and the Lightning port.
Scraping the bottom of the barrel phone case,  snag an antenna flex cable.
Also, a spidery mess of button cables. They're thin and fragile and tricky to remove intact, but they also snuggle up to a lot of waterproofed components. 
With the rear case nearly stripped, turn attention to the volume buttons that gave some trouble in the 7 Plus.
Persistent tugging with some tweezers rewards with a broken retaining flap, but this button cover still won't come quietly.
Next out is this weird c-clip looking thing.
And the button finally comes off, With two tiny gaskets, Apple is serious about this waterproofing.
This three-part mechanism is much more difficult to disassemble than the button covers, but hopefully the seal it provides means this removal procedure will be needed less frequently.
After some peeling, free the earpiece speaker and an all-new 7 MP FaceTime HD camera with deep trench isolation and auto image stabilization.
This is quite the upgrade from the 5MP FaceTime camera in the 6s.
The earpiece speaker is no slouch either, having been upgraded to serve as a second loudspeaker for legit stereo sound.
Also pluck out the solid state mini touch sensor, home "button."
