plastic grin

A forced, artificial smile; a smile someone wears despite having no feelings of happiness or joy. John seemed fine at first glance, but before long I could tell that he was wearing a plastic grin and that something was bothering him. Look at his big plastic grin—he's such a con man! I sure hope he doesn't win the election.

At reflow temperatures above the Tg of the laminate material, the z-axis expansion of the laminate is an order of magnitude greater than that of the copper, which forces the copper in tension where it plastically deforms (for example, the copper barrel becomes permanently longer than it was).
