Crystallite size L a was calculated 11 using Eq. can be expressed as follows Eq. Smooth surfaces of cross sections were prepared using a rotary microtome Leica RM, DE.

Particles were scraped off the samples, suspended in ethanol, deposited on mesh copper grids and subsequently air-dried. The analysis of crystallite size L a was performed for spruce and paper samples by applying the Scherrer equation Eq.

The obtained diffraction profiles showed broad peak bands, due to the translational and rotational disorder of the sp 2 -hybridized graphene layers turbostratic arrangement resulting in unreliable hkl reflections and making them unsuitable for estimating crystallite sizes following the Scherrer equation.

Thus, calculating the crystallite sizes with diffraction patterns from samples treated with lower laser fluence was impossible. It is therefore suggested to estimate the crystallite sizes using a fitting approach of scattering profiles developed by Ruland and Smarsly 11 , 31 , However, samples treated with high laser fluence showed more distinct and peaks which allowed a simple estimation using Eq.

The C 1 s area was deconvoluted in four main signals, The amount of iron is relatively low for both wood between 1. The differences observed within the absolute values amongst the samples are possibly related to topographic effects Fourier-transform infrared spectroscopy FTIR was performed in attenuated total reflection ATR mode with a FT-IR spectrometer Tensor 27, Bruker, Switzerland.

Mechanical tensile tests were performed according to ISO with three sample types Supplementary Fig. End tabs were glued with commercial polyurethane adhesive.

Before testing, electrodes copper wires were glued with conductive silver paste to the end of the conductive area and connected to a source measure unit , Keithley Instruments, US for monitoring the resistivity change during tensile test Supplementary Fig.

When it is use for industrial work environment use different soldering irons are used such as: Soldering Pencils: For cheap and less efficient use, soldering pencils are the best option.

Soldering Gun: Soldering gun is a better option for hobbyist and repairman due to its short warm up time. Soldering Station: Soldering station is a better version of soldering iron which is used by professional PCB designers. Rework Station: Rework stations are advanced form of soldering iron which provide all things necessary when soldering a circuit.

What are the advantages of solder? Can you start a fire with a soldering iron? The soldering iron works on the principle of heating element when current is pass through it. To overcome these difficulties a side thermostat button 27 is provided to set the temperature in this compact iron arrangement.

The detailed side thermostat control is the subject of U. Referring to U. Also, as part of the soleplate casting is a series of ribs 32 suitably formed for distributing steam in a known manner out through soleplate ports To provide normal steam from the iron, a forward generator 36 receives water drops at its front through valve assembly 37 when button 16 is in the up position all as shown and as well-known.

The water dropping into the hot steam generator 36 flashes into steam and the resulting steam is distributed by ribs 32 through exit ports For an extra surge of steam in the iron described, there is provided a rear surge generator 38 which is supplied with an extra quantity of water directly as shown to generate steam on demand, the steam following through the distribution passages formed by ribs 32 in a slightly different manner from the forward steam generator.

Cooperating with ribs 32 and soleplate 10 there is provided a coverplate 40 to define the steam distributing means from both generators 36 and For delivering water to the soleplate for steam generation, a suitable internal pump 42 and water valve structure 37, both individually known in the art, are connected respectively to buttons 18 and 16 and to the tank for manually and selectively delivering water to the steam soleplate generators 36 and This is the general operation described in said U.

With improved irons using electronic controls to sense and activate different functions, and using modern day technology, it is possible to provide a complete low voltage DC electronic circuit control means all on a single printed circuit PC board to control many iron functions such as a ready light, automatic shut-off, temperature control, or various other desired features.

However, heat is generally an enemy of such control circuitry and, of course, an iron is designed as a large heat generator. Thus, it becomes necessary to isolate the electronic circuit control means and its printed circuit board and this is usually done by locating the circuitry or control apparatus as far away from the soleplate as possible.

Typical of this structure is shown in U. Also, the use of plastic housings or shells additionally requires the control circuitry to be well removed from the massive soleplate heat generator for isolating it from the heat due to the poor conductivity of the plastic which cannot conduct heat away from the circuitry.

Since irons operate from AC house voltage, and the electronic circuitry from a low voltage DC supply, it is necessary to reduce and rectify the voltage if the iron is to be controlled by the low DC voltage electronic control means.

The ideal voltage reducer is a transformer which both isolates and reduces the voltage but this is a rather bulky extra piece of equipment and in a normal steam iron there is little or no room for such a transformer.

Further, the high ambient temperature within the iron would increase the cost of the transformer to further discourage its use.

In accordance with the invention, a power resistor can be used to reduce the voltage to a level where it can be rectified and filtered to energize the electronic circuit but such a resistor dissipates sufficient power or has high enough I 2 R loss to raise the temperature of the surrounding air enough that the plastic enclosure would be heated beyond its temperature rating.

However, the invention discloses a means to mount the power resistor on the hot aluminum soleplate so that the plastic enclosure housing shell temperature is not adversely affected.

In other words, the invention proposes the use of a power resistor which requires a lot of heat dissipation, and mounts it on the hot soleplate so that the hot soleplate itself becomes a heat sink to absorb the I 2 R loss of the power resistor.

This is applicable whether the iron is used dry or as a steam iron. This is the concept of the present invention and, in order to carry it out, a printed circuit board 44 is disposed in the housing shell 12 well away from the soleplate such as high in the handle in the forward portion as diagrammatically shown in FIG.

This control board may perform many suitable functions as in said U. Suffice to say, the AC line voltage must be reduced to supply the printed circuit board for the electronic control and this is achieved by a power resistor 46 of suitable size and design which power resistor is disposed directly on a soleplate 10 mounting so that it is in a thermally close coupling to the soleplate.

The power resistor 46 is suitably connected to the circuit board, as diagrammatically shown at 48, since it is used to reduce the AC voltage to DC voltage--losing much heat in the process. The reduced voltage can be rectified and used by the remote printed circuit board 44 to control some iron functions e.

temperature, ready lights, audio signals, and iron motion detector. Structurally, soleplate 10 may have molded directly thereto suitable spaced ribs 50 such as the pair shown. Ribs 50 form an integral part of the soleplate being molded on the inside surface thereof as shown in FIGS. In order to secure the desired close heat or thermal coupling, it is preferable that the spacing between the ribs be larger than the power resistor so the resistor can be disposed therein directly and preferably with one of its sides in contact with the soleplate as shown in FIG.

The compound locks the resistor in place by cementing the resistor against the soleplate whereby substantially all the resistor heat is conducted directly into the hot soleplate. Thus, by thermally close coupling the resistor to the soleplate by placing an excellent heat transferring or cementing compound between the resistor and the aluminum soleplate and ribs, it is possible to dissipate, for example, 12 watts of power in a ohm, 7 watt resistor which is designed for maximum surface temperature of ° F.

This dissipation of 12 watts was actually done while keeping the surface of the resistor within a ° F. limit when the soleplate was at ° F. Since substantially only the top of the resistor is exposed, in the structure described, very little area is available to radiate higher temperature heat to the plastic housing and substantially all of the heat is conducted directly into the hot soleplate which thereby acts as a heat sink.

It is an alloy whose composition can vary depending upon the nature of work. The main advantage of solder is that it conducts electricity, solidifies quickly and provide strong joints which supports the electronic components on circuit board. The repair of circuit board is also easy.

It is cheap and easy to handle. It has an insulated part to hold it in hand and a heating part which is put at point where soldering is required. When power is turn on the LED light turns on of the soldering iron which indicates heating has started.

Can you use a soldering iron on a circuit board? They are used in power electronics, for instance in transformers and chokes for power supply units, where their energy storage capability and high inductance are crucial.

In audio systems, they help in the filtering and equalization of signals. They are also used in various radio frequency applications, due to their tuning capabilities. Despite the numerous benefits, there are also some limitations associated with the use of iron core inductors.

One main concern is the saturation of the core. When the magnetic field in the core reaches a certain limit known as the saturation point , any further increase in current will not increase the magnetic field.

This can distort signals and lead to inefficiencies. In conclusion, iron core inductors are invaluable in many areas of electronics due to their high inductance, compact size, and energy storage capability.

They are particularly advantageous in power supply and radio frequency applications. However, like any electronic component, they have limitations, and their use needs to be considered carefully in the context of the specific requirements of each application.

As technology advances, we can look forward to improvements and more efficient utilization of these vital components in our electronic systems. The primary purpose of this project is to help the public to learn some exciting and important information about electricity and magnetism.
