Apparatus and methods are described including a vacuum-plasma-jig () that receives an object () during application of a vacuum plasma-treatment to a first surface () of the object). A receptacle () and base () of the vacuum-plasma-jig () are shaped such that when the receptacle () receives a portion of a second surface () of the object (), there is a hollow space () proximate to the portion of the second surface () of the object (). The vacuum-plasma-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. Other applications are also described.
