The steps towards a basic CanSat

Going through all this is necessary.

Soldering

Connecting the sensors • What goes where? • Use hand-outs

• 5V • 0V

• Analogue inputs

• Connectors

• The side with the white lines is the top side

Soldering

• Sensors

Soldering

• Start with the headers • Simple and easy starting point • A good place to practice soldering

Soldering

• Connecting components to PCB • Components on top side • Soldering on bottom side

• What is a good solder connection?

Soldering

• Good or bad?

Soldering

• Good

Soldering

• Soldering takes time (between 1 and 2 seconds) • Heat up both surfaces • Then apply solder

• End result should be: • A smooth surface • Solder all around the component leg

Practical session

• First solder the headers • Solder and test sensors one by

one • Use the correct side for the

headers • Otherwise the + and – signs are on

the wrong position
