Hand Soldering an LGA Surface Mount Chip

at 8:56 pm. Filed under DIY Hacks, Electronic Hacks

With electronic parts getting less and less hobby friendly there will come a time when you can’t get a part in a through hole DIP format. Our friend Dave from the EEVBlog has a new 3 axis accelerometer that he is playing with. The issue is that it is a LGA surface mount chip these chips only have pads on the underside which makes it a pain to work with unless you are using solder paste and reflowing. Dave demonstrates how the part can be stuck upside down onto a project board using some super glue and then using some wire wrap wire the part is able to have its pads soldered to the project board. The soldering looks simple when it is magnified this much but after soldering these wires onto a thumb drive for the VHS Tape Storage Drive Project I know first hand how hard it is.
