insert sim card on 6630 - GSM-Forum

felyks · 04-06-2007, 18:57

Hi guys.
Today I spend all day reparing 6630. It is not recognize sim card.

What I tried:
- resolder battery connector (I didnt replace with new one.)
- resolder sim tray (I didnt replace with new one.)
- remove "sim ic" aka sim filter and I make jumpers (see pic)
- remove capacitor for sim and measur it (has 100nF). I solder it back.
- I try use battery from 6600.
- I measure voltage on sim. When I turn on the phone there is some voltage for about 40 ms, then go to 0V.
- I measure sim i/o pins with oscilloscope. There was something (when voltage on sim is "on".)
- I try insert second sim.

Other stuff on phone works (mmc not tested)

I receive this nokia from friend. Nokia fall from 1-2 meters.

What else can I try? I heard to connect voltage for sim card from battery, but I am not pretty shure that will work. Sim card =1,8/3V battery= 3,7V.

Okay.. I will try this at Friday. What temperature you suggest?

nycu · 04-11-2007, 07:35

Somewhere between 320-350 degrees celsius and lots of flux paste.

felyks · 04-11-2007, 08:24

Why flux paste if I only rehot. I will not reball, just rehot.
or what do you mean with rehot?

nycu · 04-11-2007, 09:32

The flux helps spread the heat quikly and eavenly.

felyks · 04-11-2007, 10:45

Okay, I have flux in pen and in bottle. I shoud use that one in a bottle, right?

nycu · 04-11-2007, 14:10

felyks · 04-14-2007, 09:19
