    PSoC 4: CY8C4146FNI-S433T Cover/Coating

    JaSc_4288446

      Hi,

       

      On the CY8C4146FNI-S433T (PSoC 4 in 35-Ball WLCSP Package) there is a cover/coating. During the assembly process of our printed circuit assembly, this cover is sometimes damaged. This cover/coating appears to only contain the device markings such as pin 1 location and part number.

       

      Does this coating serve any purpose other than identification? And if it is damaged during the assembly process, is it going to affect the performance of the device?

       

      What is the best way to prevent damage to this coating? It seems quite sensitive to heat and pressure when the assembly is being thoroughly cleaned.

       

      Thank you.
