fanout vs. pin escape

tltoth over 15 years ago

Does anyone know what the difference is between fanout and pin escape ?

thanks

Hi
Usually, the fanout means that a routing trace is drawn out from a SMD pad and connected to a PTH or a via.
On the other hand, the pin escape means it is a neck-down trace such as a trace between fanout vias or BGA pads or PTH pins.
In addition, such as the following,
Nominal Trace Width:6mil, partially 4mil(pin escapes only)

Hope this helps.

Regards,
Tomo
