The AoyueINT2703A+ Advanced LeadFree Repairing System is a

reworking equipment that combines the functionality of Hot Air Gun,

SolderingIron,SmokeAbsorber,andDesolderingGuninonepackage.

ThedualportsystemoftheInt2703A+allowssimultaneoususeof

thedesolderinggunandsolderingiron.

The nozzle is specially designed with air spreader technology to

disperseheatandairevenlygreatlyenhancingtheheatoutputformore

effective reflows. When paired with our fourth generation BGA nozzle

technology, reworking larger BGAs (CPUs GPUs) will be even more

efficientandrepeatable.

It has several safety features such as the autocooling process of

the Hot Air Gun. This functionality protects the device (and its

components) from excessive heat upon reaching any of the following

conditions: (1) when the soldering gun remained idle on its resting

handle after a certain period and (2) when the temperature of the

deviceisaboveasafethresholduponturningoff.

It has several advanced features such as solder iron and
