    Hello Fellow Modders,

    So I feel really stupid now: I have tried to solder all the connectors for the GPIO pins onto the board and I suppose my soldering skills are shot. There is a chip that have the numbers 620 on it and I've now fried two of them - ad in they're literally melted (the other was on a WRT54G ver.3.1 - I loved that router!). See the pictures below for details.

    My question is - can I replace this chip and, if so, any tips on keeping a steady hand? Also, it seems to be the CLK (clock/timing?) part so I was also wondering if there is a way around or another place to solder the points for the MMC mod.


    I'm running DD-WRT version 23 SP3 std. on both and they worked great before I started tinkering.

    Thanks in advance. Email is jason1550 <@/at> gmail <./dot> com.

    bad luck, must need very fine tip soldering iron and steady hand!

    I guess that's just a 4 way resistor pack you've cooked, but whether the resistors are 620 Ohms or 62 I couldn't tell you! The way it would be changed in a 'lab' would be with a infra-red heat source with a metal mask over all the surrounding chips. Do you have a local University with a electronics lab nearby?
