Juotepumpulla

Juotepumpulla, also known as a desoldering pump or solder sucker, is a simple mechanical device used in electronics soldering to remove molten solder from a joint. It typically consists of a hollow cylinder with a plunger mechanism, a spring, and a nozzle made of heat-resistant material. When the plunger is pulled back, it creates a vacuum inside the cylinder. When the tip of the pump is placed near a heated solder joint, the trigger or button is pressed, releasing the plunger and rapidly drawing the molten solder into the cylinder, effectively cleaning the joint.

The primary purpose of a juotepumpulla is to correct soldering mistakes, remove excess solder, or desolder components for repair or replacement. It is a common tool in hobbyist electronics work and professional repair settings due to its affordability, ease of use, and effectiveness in many desoldering tasks. Different sizes of nozzles are available to suit various soldering applications. While effective, it may not always remove all traces of solder, and for more critical desoldering operations, desoldering braid might be preferred as a complementary tool. The internal mechanism can be cleaned periodically to ensure optimal vacuum pressure and prevent solder buildup from affecting performance.
