TXMC638 User Manual Issue 1.0.2

Page 11 of 86

3 Handling and Operation Instruction

ESD Protection

3.1

The TXMC638 is sensitive to static electricity. Packing, unpacking 
and all other handling of the TXMC638 has to be done in an ESD/EOS 
protected Area.

Thermal Considerations

3.2

Forced air cooling is recommended during operation. Without forced 
air cooling, damage to the device can occur.

Please also note chapter “Thermal Management”.

Assembling Hints

3.3

When disassembling the TXMC638 from carrier board please keep 
the mechanical stress as low as possible.
