An electronics technician needs to remove excess solder from a circuit board contact using a manual spring-loaded desoldering pump (solder sucker). Arrange the procedural steps in the correct sequence from first to last.
- 1Depress the spring-loaded plunger until it locks into the cocked position.
- 2Apply the heated soldering iron tip to the joint until the solder liquefies completely.
- 3Position the heat-resistant nozzle of the pump directly against the molten solder pool.
- 4Press the actuator release button to create a vacuum and draw the molten solder into the tool cylinder.
Cevap
The correct sequence is: prime the plunger into the locked position, melt the solder with the iron tip, place the nozzle directly over the molten pool, and trigger the release button to vacuum the solder.
A manual desoldering pump relies on rapid vacuum suction. The tool must be pre-cocked before thermal application. Once the iron melts the joint, the nozzle is placed adjacent to the iron tip over the liquid pool, and the release button is pressed immediately to extract the molten alloy before it solidifies.
