ESD Warning 

 

 

Electronic components and circuits are sensitive to 
ElectroStatic Discharge (ESD). When handling any circuit 
board assemblies including Connect Tech COM Express 
carrier assemblies, it is recommended that ESD safety 
precautions be observed. ESD safe best practices include, 
but are not limited to: 
 

 

Leaving circuit boards in their antistatic packaging 
until they are ready to be installed. 

 

Using a grounded wrist strap when handling circuit 
boards, at a minimum you should touch a grounded 
metal object to dissipate any static charge that may be 
present on you. 

 

Only handling circuit boards in ESD safe areas, which 
may include ESD floor and table mats, wrist strap 
stations and ESD safe lab coats. 

 

Avoiding handling circuit boards in carpeted areas. 

 

Try to handle the board by the edges, avoiding contact 
with components.
