iPhone 5G Antenna Replacement

How to replace the 5G UW antenna in your iPhone. Video includes approximate diode mode values for the connection so that you can make sure the antenna is properly installed before putting the logic board back into the housing.

Hello had the soldering iron at 400 C didn't want to stick please what flux you use not on the outside of the pads but on the inside the small square ⬜⬜⬜⬜ ⬜⬜⬜⬜ ⬜⬜⬜⬜ Im doing this right now but the 5G Antenna Wont Stick the to the small boxes ⬜ please help

I have my soldering iron at 840 F so that might be why it was a little easier for me. The flux is only on the outside of the antenna as I found it too difficult to prevent it from sliding around when there was flux underneath. That said, I think that any decent SMD flux should work in this situation.

*840F.

Not a fan of that connecter to solder. The iPhone 14 Pro Max Bluetooth antenna is soldered the same way and it’s a pain to fix if you accidentally add too much heat when fixing the back glass😅

[@GoCellPhoneRepair]

Yeah, strange way to do it in my opinion.

[@LILGRIZZLY]

What kind of flux you to make the Antenna stick specifically please im trying to do my own repair iron Good video btw

[@GoCellPhoneRepair]

I'm using 2UUL from Union Repair at the moment but note that the flux is only on the outside of the antenna connector. The pads underneath will still bond and I don't apply it there to prevent it from slipping around. I've used Mechanic 225, Kingbo, Amtech... all of them work just fine.

Thank you

[@omodelesalu]

When its ripped, does the phone still get 4G network? Or do you have to replace it to get 4G network?

[@GoCellPhoneRepair]

You should still get 4G and in many cases 5G can still function. This antenna is strictly for millimeter wave 5G that you will find in crowded areas like airports.

[@MazenNour-n4l]

is a value of .70 instead of .59 okay?

[@GoCellPhoneRepair]

Sounds close enough. There will be some variance based on different meters.

[@smoothlarryhughes]

where does the other end of the antenna wire connect? I was taking the motherboard out of an iphone 13 pro and tore the same flat cable.

[@inderjeetuppal6462]

Does it work in other countries like India, uk these 5mm uw antenna flex?

[@GoCellPhoneRepair]

As far as I know it is mainly in the US and almost exclusive to high density events like concerts, athletics games, etc.

[@inderjeetuppal6462]

@@GoCellPhoneRepair high density as in?

[@GoCellPhoneRepair]

An exceptionally large number of devices connecting to a single tower.

Where are tests points ? Thanks !

Will this fix my cellular issue on my iPhone 14 pro ? It’s stuck on searching and no service, when I go to setting and click cellular It says Error?

[@GoCellPhoneRepair]

Check settings>general>about and scroll down to modem firmware. There should be a version number there. If not, you have bigger problems, like a bad baseband pmic or some fractured solder joints. The 5G antenna only picks up UW frequency and should not prevent service altogether.

[@nelzaecaasi3915]

Hello. Do you think same diode values in Iphone 14 pro max

[@GoCellPhoneRepair]

I believe so.

[@mazennour9515]

Why don't you use the heat gun?

[@GoCellPhoneRepair]

It’s pretty easy with the iron and anytime I can avoid heating the bottom board I do so because the components on the other side are very sensitive. Using hot air would radiate more to the other internals.
