Desoldering pump guide

For electronics and hobbyists is one desoldering indispensable if individual components of printed circuit boards must be solved. Depending on the intended use, they are available in mechanical or electronic versions. Both models are equally suitable for vacuuming solderHowever, there are differences in handiness and suction power, especially in continuous operation.

Mechanical desoldering pumps

All manual desoldering pumps have a heat-resistant plastic tip, such as Teflon, which does not adhere to the solder. They consist of a cylinder with recessed piston, which is tensioned and released by means of a helical spring. When pressing a button, the spring is released and provides a negative pressure, which absorbs the liquid solder. The accumulated solder cools in the cylinder and is stored there. When re-tensioning the spring, the remains fall out. Mechanical desoldering pumps are cheap and well suited for hobby electronics. Nevertheless, some points are to be considered. Cheap desoldering pumps usually have to be cleaned and regreased more often, the springs do not last too long and not all solder joints are completely freed from the solder. Such simple pumps are usually already available under 2EUR, for example the Wentronic desoldering or cheap models from Silverline. They are big, fit well in the hand and the opening of the tip is large enough to free even thick solder joints from solder.
Disadvantages of the large pumps are recognizable in continuous use: they are difficult to clamp and not always easy to operate with one hand. Anyone who has to solder many solder joints quickly reaches its limits.
Smaller and more manageable pumps are more expensive, but show their benefits from the beginning. Often they can be operated with one hand and also with one hand in the AshtrayDrain. The constant putting out of hand of the soldering iron during the clamping process is eliminated – a faster work is guaranteed. Mostly they are made of higher quality materials and therefore need less frequent cleaning. Often the tip is also finer, enabling more accurate desoldering on tightly printed circuit boards. The ERSA 0VACX model, which is not only distinguished by its ergonomic shape and suction power, but also easier to clean than other models, has proven its worth.

Electric desoldering pumps

In the professional field, electrically operated desoldering pumps are used. In these devices, the Enttötspitze is usually made of metal, it transfers heat to the Lotstelle. The heated solder is also removed by means of vacuum suction function of the solder joint. For this purpose, the pump is connected to a vacuum supply or the negative pressure is generated by means of a vacuum pump. The triggering works here by means of a hand switch or foot pedal.
Electric pumps are not as expensive as you might think. Cheap devices only cost about as much as an expensive mechanical pump. High-priced models such as the Gowe electric vacuum pump are suitable, among other things, for desoldering very fine parts such as microchips or closely soldered circuit boards on which a large number of solder joints are present. The insert guarantees a clean working as well as fast progress without the soldering ironto have to leave the hand. Even combined solder desoldering stations are a good alternative because the heater does not need to be purchased twice.
When using electric pumps with temperature control, it is important to pay attention to what temperature is preheated, because sensitive components can be damaged by the heat.

Cleaning the desoldering

Manually operated desoldering pumps pick up the liquid solder in the cylinder and after cooling, the material falls out of the opening during clamping. Depending on the quality, the opening clogs over time and the pump must be disassembled and debris removed. With cheap models, this can happen even more often during a desoldering operation. This is annoying and costs unnecessary time, which is why the purchase of a more expensive pump is well worth, for example, the model Edsyn Soldapult Deluxe, which even acts antistatic. Or you can create several desoldering pumps at the same time and clean them all after use.
Electric pumps usually take up much more solder before they need to be cleaned. This makes work easier, especially when a large number of solder joints have to be depleted. Electrical appliances contain a solder pot, which only needs to be emptied from time to time. The tip does not clog and rarely a filter needs to be replaced. The use is worthwhile especially for multiple killers.
