Hi Adrian, Thanks again for all your tips and tricks about soldering the SMD. I think I will be able to build the DDS board successfuly now ! I wrote to Kari from RF Device to buy a new DDS board with resistors, ferite beads, inductors, capacitors, diodes, transistors and all the IC's including DDS ...

Hi Adrian,

Thanks a lot for your answer to my post.

I have some other questions : what kind of flux and solder did you used and what was the temperature of your soldering station when you soldered the DDS and PIC ?

Thanks again for your answers.

:o Hello, When soldering DDS an PIC on DDS board I encountered many difficulties even using flux, small gauge solder (Sn62Pb36Ag2 0.3 mm) and a soldering station with a small tip so I made many solder bridges and was unable to remove them using solder wick and bent IC legs and broke board tracks. So ...

Good morning,

I was be able to buy the needed parts from RFDevice.

All is right !

Good evening, I've bought a few months ago the TRX2A kit but left the kit in the box. Last week I decided to begin the assembly with DDS board, but unfortunately I broke the PCB with resistors, trimer, inductors, ferrite beads, capacitors, diode, transistors and IC's including DDS and ...
