Such heating is intended for uniform and smooth heating of the microcircuit case before soldering the radioelectronic The components on the boards are mainly hot air, because with this type of soldering, heat transfer occurs from the heated microcircuit to the printed circuit board, as a result of which it takes a rather long time to heat up the necessary element, which can cause it to overheat. Also similar device It will help to save the printed circuit board itself, since in case of uneven heating it can be deformed and delaminate.
This device is an aluminum plate with magnetic legs, equipped with a “pocket” in which a heating element based on posistors is placed, which indicates its increased reliability (due to the absence of components that increase the likelihood of interruptions in operation, such as thermostats), and a long service life , economy (due to low energy consumption), in addition,
Thanks to the self-regulating qualities, posistor heaters can dispense with elements of the control system and stabilizing components, as well as without protection against overheating.
The surface heats up evenly and quickly enough (according to the seller, in 30 seconds the heating temperature will reach about 250 ° C).
The main characteristics of the device are as follows:
• power: 300 W;
• voltage: AC 220 V;
• Dimensions: 120mm x 70mm (L x W).
Note that according to the seller, the plate size may differ from the declared by about 1 cm.
Such a device will be a worthy replacement for the already become a “classic” household iron.
Cost: ~ 350
