Least Expensive Swing Set

3 (or FPC) - iPhone iPhone 3G 3G/3GS

This "famous" connector to its reputation, alas, the frequency with which changes to the other world. I have read in some forum complaints from users who describe him as a weak component, while others often forced break because improperly.

My opinion is that both are right: the datasheet this connection shows as "insertion tolerance (tolerance of insertion, or how many times you can open / close)" 10 times ", ie 10 times. It will also be a nominal value, and therefore subject to a margin of tolerance, but still little is. Moreover, many times not knowing how to use it, remove the flat without lifting the tab stop, or that is raised too hard, so the connector transfers.

Once unplugged the FPC connector (also called "slot 3") here, you should clean the pcb from residue of the old "pool" - is actually an alloy of lead-free is not easy to remove - and spread a infinitesimal amount of flux, and new pond. Cleaned a isopropyl alcohol, and here's the logic board ready to weld a new connector:

The brilliance of the new pond is an indication of the goodness of the weld. Got a new connector, apply an increasing amount of infinitesimal flux on the legs, is positioned loooong patiently on the seat, making sure to match well the pin, then proceed to the weld. My advice is to establish a first leg in a corner, then replace perfectly and proceed with soldering all the pins on one side, then move on to another. Here is the finished work:

A completed welding the pins will be checked one by one, making a slight lateral pressure, and must not move any way .. if they do it will be necessary to re-weld, always adding an infinitesimal amount of flux and the same pond.

Enjoy!
