Desoldering Pump

The DP-366A is an extended-length ESD manual desoldering pump measuring approximately 27.5 × 333 mm. Official information specifies suction greater than 38 cm-Hg, making it suitable for multilayer PCBs and larger solder joints.

It is suitable for electronic production, repair, and desoldering where static control is required. The ESD design reduces the risk of tool charge but must still be used with a complete grounded antistatic workstation.

The ESD housing supports static control, while the longer barrel provides strong instantaneous suction. Compliance with a facility's required resistance range must still be confirmed from documentation and on-site testing.

The strong suction is suitable for multilayer boards and joints with larger amounts of solder, but the solder must first be melted completely. Nozzle distance from the joint also directly affects performance.

De-energize the circuit, cock the pump, melt the solder completely with an iron, position the nozzle close to the molten solder, and trigger it immediately. Add flux if necessary and avoid heating the pad repeatedly for an extended period.

Official information positions it for multilayer PCBs and larger joints above approximately 5 mm. Actual performance depends on solder volume, thermal mass, nozzle size, and seal condition.

No. An ESD tool is only one part of static control. Operators must still use grounded wrist straps, work mats, grounding points, and environmental monitoring according to site requirements.

After the nozzle has cooled completely, open the collection chamber, remove debris, and inspect the piston, spring, and seals. Prevent solder from blocking the air path and test suction after reassembly.

Both are high-suction manual desoldering pumps. The DP-366A emphasizes an extended ESD design, while the DP-366P emphasizes a rear-pull mechanism, non-slip grip, and replaceable nozzle. Select according to ESD requirements and handling preference.

Confirm the ESD specification, availability of nozzles and seal consumables, suitability of its size for the work space, and the intended market package. For production use, conduct an actual desoldering trial first.
