Soldering of small IC`s without a PCB. Sometimes there is no Evaluation Board or a PCB, for such a case: hand soldering method if a result should be available on the same day. This method takes some hours to solder everything. IC package here: TSSOP-20 EP, Pitch 0.65mm. IC mounted upside down. Exposed Pad soldered with a copper heatsink.

Advantages:

• ready within some hours, if no PCB available
• pins and soldering junctions are easy accessable with voltage probe and current probe
• passive parts easy changeable
• good GND and signal quality
• building in 3D possible
• lowest price

Disadvantages:

• not for more than one piece
• takes some hours to build
