Is this what a damaged FL11 looks like on a iPhone SE?

I haven’t had much luck finding a clear image of what a healthy iPhone SE FL 11 looks like. I assume that I am looking at just the pads, and that my “x40 photo 1” shows one of the transistors that popped off. :(

Hays Clark no transistors at all. There are 3 capacitors and one coil (Ferrite Bead)

Reference Designator C2400 is a 56PF 5% 16V capacitor in a 1005 package

Reference Designator L2400 is a 120 Ohm 210 MA ferrite bead in a 1005 package

Reference Designator C2410 is a 56PF 5% 16V capacitor in a 1005 package

Reference Designator C2411 is a 100PF 5% 16V capacitor in a 1005 package

Yes, looks like all you have are the solder pads.

A 01005 Ferrite bead is essentially a speck of dust if it's laying around on your desk or bench. On your board, it would just look like a dark gray rectangular package measuring ~0.01 inch by 0.005 inch.

You are probably missing FL11, aka FL2400 in the SE —and definitely missing two of the caps. The picture is clear for the two caps, and less clear at FL2400.


If the symptoms that this phone are having are a match for missing gas gauge filter, then you know that FL2400 is not on the board.


Gas gauge problems in SE:

With a charged battery phone will reboot every 3 minutes

Battery percentage reported wrong—will say 1% or 100% or jump up and down erratically


3utools software does not “see” the battery percentage in battery details.


With a dead battery, the low battery “plug me in” logic will not engage, the phone will try to boot instead and show apple logo then loop.


usb ammeter will show low charging current, less than 0.5A


If those are the symptoms, then yes—-send this phone out for SE “little peckers replacement”

I see that you contacted me on iPad Rehab Microsoldering website, but I’m answering here to help anyone else with a similar problem in the future figure out if they have a little pecker problem ;0
