Question Resistor film chipping

[nsharpeaus]

Hi All !

I hope ye are keeping well !

I have recently received a board for my electronics hobby and some of the outer film on the PTH resistors seem to be chipped. The metal casing underneath is showing.

I assume the resistors are not populated into the board in this condition. I assume it has something to do soldering process?

Does anyone know why and how it could happen please?

Thanks in advance,

Noel.

maybe while bending the resistors, the used tool was too close to the component itself
