Conrad Thermostat Variable Temperature Switch Kit With Sensor 192082 Hoja De Datos

While soldering the components see to it that they (unless indicated otherwise) 
are soldered on to the plate without any gap. All projecting connection wires are 
cut directly above the solder joint. 
Since the solder points in this kit are very small ones, lying partly very close to 
one another (risk of solder straps), the soldering must be done here only with a 
soldering iron with a small soldering tip. Do all the soldering and assembly work 
very carefully. 

If you do not have much practice in soldering, then it is advisable to go through 
these soldering instructions before you actually start soldering. Soldering must be 
learnt. 
1. Never use soldering grease or soldering fluid when soldering electronic 

components. These contain acids, which can damage the components and 
conducting paths. 

2.  Only electronic tin SN 60 Pb (i.e. 60% tin, 40% lead) with a colophony core 

may be used as soldering material, which at the same time also acts as 
soldering flux. 

3.  Use a small soldering iron with max. 30 watt heating power. The soldering tip 

should be tinder-free, so that the heat can be discharged properly. This 
means: The heat from the soldering iron must be conducted properly to the 
point to be soldered. 

4.  The soldering itself should be done quickly, because a longer duration of 

soldering can damage the components. Similarly, it also leads to release of 
eyelets or copper pathways. 

5.  For soldering the properly tinned soldering plate is kept on the point to be 

soldered in such a way that it touches the component wire and the conducting 
pathway at the same time. Simultaneously, soldering tin (not very much) is 
added, which also gets heated up. As soon as the soldering tin starts to flow, 
take it away from the solder joint. Then wait for a moment, till the solder left 
behind has blended properly and then remove the soldering iron from the 
solder joint. 

6.  See to it that the component you have just soldered is not moved for approx. 

5 seconds after you remove the soldering iron. What remains after that is a 
silvery shining, smooth solder joint. 

7.  A prerequisite for a smooth solder joint and good soldering is a clean, non-

oxidised soldering tip. With a dirty tip it is absolutely not possible to do a clean 
soldering. Therefore, after every soldering, wipe away the extra soldering tin 
and dirt with a damp sponge or with a silicone wiper. 

8.  After soldering the connection wires are cut directly above the solder joint with 

a wire cutter.
