摘要：
Embodiments relate to a test method for testing an unpopulated printed circuit board. The method can involve the steps of: exposing the unpopulated printed circuit board to temperatures of a reflow soldering process in a first step; and testing the electrical connections of the unpopulated printed circuit board. Embodiments also relate to a test device and a method for producing populated printed circuit boards.
