Abstract
Disclosed is a test system for testing electric connections, in particular soldered connections, between electronic components and a printed circuit board to be tested, characterized in that the test system includes a subassembly, which is movably mounted in a housing of the test system, and a current and/or voltage source for energizing the circuit board to be tested, the current and/or voltage source being arranged in the housing of the test system in such a way as to be movable in at least two directions in space.
Claims12
A test system for checking electrical connections between electronic components of a circuit board, comprising:
- a temperature measurement device configured to measure a temperature of the electrical connections and the electronic components and to determine characteristic thermal values of the electrical connections and of the electronic components;
- a housing and
- a communication interface having at least three electrically-conductive contact tips, which, by contacting with a contacting arrangement on the circuit board having several contacting points, enable data exchange with a data memory of the circuit board, wherein the data exchange takes place according to a communication protocol.
A test system for checking electrical connections between electronic components of a circuit board, comprising:
- a temperature measurement device configured to measure a temperature of the electrical connections and the electronic components and to determine characteristic thermal values of the electrical connections and of the electronic components;
- a housing;
- and
- a test module which is movably arranged in at least two spatial directions arranged in the housing,
- wherein the temperature measurement device is rigidly connected to the test module,
- wherein the test module includes a sensor device for detecting an identification feature of the circuit board, including a barcode, a serial number, or a QR code, wherein the test system is configured to use the identification feature to retrieve a record of a permissible temperature profile for that type of board.
A test system for checking electrical connections between electronic components of a circuit board, comprising:
- a temperature measurement device configured to measure a temperature of the electrical connections and the electronic components and to determine characteristic thermal values of the electrical connections and of the electronic components;
- a housing;
- and
- a test module which is movably arranged in at least two spatial directions arranged in the housing,
- wherein the temperature measurement device is rigidly connected to the test module, and wherein the test module includes at least one tool component for repairing electrical connections on or at the circuit board, wherein the tool component is controlled on the basis of measured values determined by means of the temperature measurement device.
A test system for checking electrical connections between electronic components of a circuit board, comprising:
- a temperature measurement device configured to measure a temperature of the electrical connections and the electronic components and to determine characteristic thermal values of the electrical connections and of the electronic components;
- a housing;
- a test module which is movably arranged in at least two spatial directions and toward an underside of the circuit board arranged in the housing;
- a communication interface;
- and
- at least one pin-shaped test tip, wherein the at least one test tip is configured to be freely movable above the circuit board to be tested, wherein the at least one test tip is arranged to be guided from above for testing an electrical integration of electronic components on the circuit board by determining resistance values of contact points on the circuit board,
- wherein the communication interface and the temperature measurement device are rigidly connected to the test module.
