Hi, I'm trying to install a d2ckey chip using the alternate method (bottom side) but can't seem to get the solder to stick to the holes. Has anybody tried this and if so, how did you get the solder to stick to the hole. Some pictures would be great. NOTE: I tried soldering to the chip pins and a couple of the traces were lifted. Luckily it is still working. I don't want to solder to the pins anymore but instead using the alternate method. Thanks.
