没有听说过用explosion的,你可以参考IPC-A-610D中的10.2.2 Laminate Conditions – Blistering(起泡)and Delamination(分层):
Blistering - Delamination in the form of a localized swelling
and separation between any of the layers of a lamination base
material, or between base material and conductive foil or protective
coating
Delamination - A separation between plies within a base
material, between a base material and a conductive foil or any
other planar separation with a printed board.
其实就口语来讲,用得最多的应该是Popcorn(爆米花),老外习惯用法。
