PRE-REPAIR DEVICE CHECK-IN

•Philips screwdriver

•Spudger

•Tweezers

•Isesamo

•Pentalobe screwdriver

•Magnetic Mat

•Samsung galaxy s7 Digitizer/LCD

TOOLS NEEDED

•Always operate the heat gun on the lowest setting.

•Keep face, hands, hair, and clothing away from the air stream.

•The air nozzle also becomes extremely hot. Never grab the heat gun by the nozzle.

•Never operate the heat gun by laying it on its side on a table. It should be firmly grasped in one hand

at all times during usage.

•Never operate near flammable or explosive liquids and vapors. Cleaning supplies and the 3M #94

Primer are of concern. Make sure fumes are absent from the work area before operating the heat gun

•The heat gun nozzle should never get closer than 2“ to the object being heated.

•Keep heat gun moving. Never stay in one spot.

HEAT-GUN PRECAUTIONS

•Magnetic Pad: During the repair, you will be utilizing a magnetic pad to organize the plethora of

differing screws that you will be pulling out of the iPhone 6S. Below is a list of several internal

components of the iPhone 6S that should never be placed on the pad, or you risk damaging the

hardware or erasing client data:

•LCD/Digitizer Assembly

•Cameras

•Motherboard

•Battery

•Speaker

ADDITIONAL PRECAUTIONS

•Power on/off: To avoid any damage to the hardware during the repair, it is best to have the device

powered off until you can get to and disconnect the battery.

•Battery: Never unplug any flex cables unless the battery has been completely disconnected to avoid

frying your hardware. Do not plug the battery back until all cables have been reconnected.

•Release Screws: Apply pressure on the screw and twist counterclockwise to initially loosen it, then

lighten the pressure and continue twisting until the screw is gently released. Make sure you have

properly sized screwdrivers available for the repair.

•Pin Connectors: extremely fragile and must be plugged or unplugged with extreme caution.

•Battery connector: held down by light adhesive and solder. If not cautious it will come off the

motherboard. Very time consuming to be repaired. Do not break it in the first place.

•Motherboard: small surface mount components can be easily damaged if they are nicked by the

spudger. Always take your time and never touch the surface of the motherboard.

ADDITIONAL PRECAUTIONS

STEP 1 •Power off device.

•Remove sim card.

Disassemble the device

Tools: sim card ejector

STEP 2 •The next step requires you to heat around the frame

of the back glass. Now when you heat around the

frame do it in a constant movement do not let it rest

in just one area.

•You will need to use some type of cards or thin picks

so slide underneath each part you release from the

adhesive so it doesn’t stick back down.

•Take the isesamo or painters knife and slide it in

between where the glass and frame meet. You want

to slide it around the frame if it seems the adhesive

has cooled down heat around the frame again. This

process you will continue as you try to loosen up the

whole back glass.

Disassemble the device

Tools: isesamo or painters knife, heat

gun, plastic cards
