Title: Perfboard for very small chip?
Post by: bfish3385 on May 16, 2012, 10:29:05 PM

May be simple question, but...

Does anyone know a good way to hook up a chip when the spacing is very small between the interfaces and only half-circle edges are exposed?
I bought this chip:

in hopes that I could rig it up to my circuit (I moved all the parts from the $50 dollar robot to a breadboard) so I can get UART via bluetooth working. From what I can tell from the tech pub they have at the website above, there is a 1.38mm spacing on the sides to 1.5mm spacing on the bottom between pins -- so definitely not the standard 0.1" spacing. I tried a few searches for perfboards that have pre-punched holes of this size but haven't come up with anything that seems hopeful -- any ideas/special techniques?? It looks too small to solder with regular tools...

After this I can attempt to hook up the Tx/Rx pins, ground  + power and then work out trying to get the usb dongle to recognize the device...but one step at a time!

Thanks a lot in advance....
