- Functional tests: Perform several tests to check the correct operation of the torque limiter, such as load and endurance tests.
-
Electronic Boards
- Diagnosis: Identify the problem and determine the root cause of the defect on the board. This involves electrical testing, a visual inspection and the use of specialised diagnostic tools to identify faulty components or circuits.
- Removal of defect components: After identifying the defective components, desolder or remove them. This can be done using soldering and desoldering tools, such as precision soldering irons and rework stations.
- Replacement of components: Replace the components with new or repaired components that are compatible and meet the required specifications ensuring that the components are suitable in terms of value, type and tolerance.
- Welding and assembly: New components must be soldered using appropriate techniques, such as reflow soldering or hand soldering. If required, adjust or repair the electrical connections and circuit traces on the board.
- Functional tests: Check correct operation of the repaired board by performing electrical tests, voltage measurements and continuity tests, among others.
