Hi,


I want to test a SIM868 GSM/GPRS + GPS module, but I’m not sure what the best approach is for connecting it temporarily without permanent soldering.

• The module I have is an LGA version (surface-mount).
• I want to avoid soldering directly if possible.
• I’ve heard about LGA sockets, breakout boards, and pogo pin adapters, but I don’t know which is most practical for testing.

Which method would you recommend for safely testing the SIM868 module, especially if I want to connect it to a microcontroller for experimentation?


Thanks in advance!

 

Are you wanting to socket this?

Pogo pins will work but I don't think there are any small enough.
I have worked with companies that make sockets, but their prices are high.
One method I used: We made a PCB with the matching footprint. But you can't reliably just push the two together. There is a company in Japan that makes a soft flexible piece of rubber that is about 1mm thick. It has millions of vertical wires hidden inside. It makes a reliable connection from the Device Under Test to a PCB. I can't remember the companies' name now.
