Developing a fast cordless soldering iron via induction heating

Geometrical effects in a Joule heating problem from miniature soldering

The soldering of small, delicate electronic devices by means of a blade thermode (a small, thin, rectangular or -shaped soldering iron) requires the lower side of the thermode to have a uniform temperature distribution. This is not easily obtained: during start-up the corners tend to be too hot, and too cold in the stationary phase. In the present study the various aspects that determine the he...

designing a fast locking pll

a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...

Development of a Model for Induction Heating

Frequency Selectable Induction Heating Targets

This paper examines a scheme for developing frequency selectable induction heating targets for stimulating temperature sensitive polymer actuators. “Frequency selectable” implies that each target has a frequency at which it heats preferentially compared to other remaining targets. Single-turn conductors whose critical dimensions are small compared to their associated skin depth (over the freque...

A reactor for high-temperature pyrolysis and oxygen isotopic analysis of cellulose via induction heating.

A reactor for converting cellulose into carbon monoxide for subsequent oxygen isotopic analysis via continuous flow isotope ratio mass spectrometry is described. The system employs an induction heater to produce temperatures >or=1500 degrees C within a molybdenum foil crucible positioned by boron nitride (BN) spacers within a quartz outer sleeve. For samples of a homogeneous working standard ce...
