Important additional soldering hints 

 

The MMC Reader is located on the opposite of the SLIM-Lumberg connector. 
Therefore the risk to damage the plastic material of this MMC-Reader is potentially high if excessive 
heat is used while removal or soldering of the SLIM-Lumberg connector. 
 
Please follow these instructions: 
 

a)  Remove the SLIM-Lumberg connector with a soldering iron and Desolder Wick 
b)  Clean the Pads afterwards 
c)  Solder the new connecter by using soldering iron under consideration of the max. allowed 

temperature range.
