Abstract
An electrical probe apparatus for facilitating the testing of printed circuit boards is constructed in a gas tight manner. This allows the printed circuit board to be held by suction without losing vacuum pressure through the probe. A silicon rubber sleeve serves as the vacuum seal, and its resilience urges the probe into firm contact with the circuit under test.
