1. Apparatus for use with an object having first and second surfaces and a vacuum-plasma chamber, the apparatus comprising:
a vacuum-plasma-jig configured to receive the object during application of a vacuum plasma-treatment to the first surface of the object within the vacuum-plasma chamber, the vacuum-plasma jig comprising:
a receptacle configured to receive at least a portion of the second surface of the object when the second surface is placed upon the receptacle; and
a base upon which the receptacle is disposed,
wherein:
the receptacle and base are shaped such that when the receptacle receives the portion of the second surface of the object, there is a hollow space proximate to the portion of the second surface of the object, and
the jig defines a channel therethrough, a first end of the channel opening to an exterior of the vacuum-plasma-jig and a second end of the channel opening to the hollow space, a ratio of a length of the channel in mm to a mean cross-sectional area of the channel in square mm being greater than 100:1.
