What is the best soldering iron and tip to use on circuit boards?
Soldering irons come in a variety of sizes and shapes. There is a wide selection of soldering irons, soldering pencils, soldering stations and soldering guns available on market in the USA.
Which soldering iron is the best soldering iron for you depends on the soldering work you are planning to do and how often you are planning on using your soldering iron. The following four factors should be taken into consideration when picking a soldering iron that will be used for soldering projects on circuit boards:
1) ) type of the soldering tools
2 wattage of the soldering iron
3)temperature control
4) tip size and shape
Types of soldering tools
All soldering tools can be divided in four different groups
-Soldering pencils
-Soldering station
-Soldering rework /repair stations systems
-Soldering guns
Soldering pencils
Soldering pencils are the simplest (and the cheapest) soldering tool. Soldering pencils are good only for simple do-it-yourself projects. The price range of the soldering pencils is $10-$30
Soldering stations
Soldering station consists of two parts: soldering pencil and a power station. Soldering pencil is attached to a power station. Power station controls temperature of the iron tip in the wide range. It automatically keeps the iron tip at an appropriate temperature. Desired temperature of soldering iron is set with knob on the face plate of power station. Soldering station can be used for most of soldering projects. It can be used for soldering of through-hole components on circuit board as well as for soldering of very fine surface-mount components as small as 0603 and 0805. The price range of the soldering stations is $40-$150.
Soldering rework /repair stations systems
Soldering rework/repair systems are complex soldering tools which are mostly used in industry or in the high-volume manufacturing facilities. This soldering systems are the most expensive soldering tools since they usually consist of power station and 4 or 5 hand pieces including soldering iron, hot-air gun, tweezers , vacuum pump which is used for the de-soldering work. The price range of the soldering systems is $250-$2500.
Soldering guns
I do not recommend using soldering guns for fine soldering projects on circuit boards.
The most popular brand names for soldering irons in the USA are Weller, Pace and Hakko. Aoyue soldering irons are less popular brand name in the United States then Weller or Pace. However, Aoyue soldering irons are much cheaper and they are good combination of quality and price.
There is a wide selection of iron tips. Iron tips come in different shapes and sizes. For most soldering projects you can use screwdriver tip 0.062" or 0.032". For fine soldering projects and for soldering of small surface-mount components you can use conical tip 1/16".
Conclusion
I recommend a temperature controlled 50W soldering station. This soldering station will be excellent tool for most of soldering projects. My top recommendations are:
-Weller WESD51 soldering station (digital)
- Weller WES51 soldering station (analog)
- Hakko FX-888 soldering station
- Aoyue 2702A soldering station
- Pace ST-25 soldering station
Can you take smiggle skins off?
Yes You Can Take Them Off!
But You Have To Peel Them Off Very Carefully Or They Will Rip And Leave Stains On Your Device.
Electronic temperature sensor?
Electronic temperature sensors are basically a transducer which convert the heat energy to equivalent voltage . they are thermocouple and also some heat sensing device are available which change their electronic parameter when temperature change those are used in vehicle and aircraft for temperature controlling and cooling.
Additional hard ware refer to digital circuits in electronics domain. the term extra hardware means extra logic devices gates after using universal devices like multiplexer decoder and memories. the number extra hardware can be fixed by using proper solving of k maps.
yes Philips is really a good brand in the field of electronics. they manifacture cfl electronic radios, cassette player and music system . they are also providing good quality and effective coast(economical). so i will you recommened you for Philips.
What are the 2 ways to find out which is the positive leg and which is negative - led?
On an LED, one leg will be shorter than the other.
The shorter leg is the negative polarity.
the back to back connection of any component is called series connection
for example
if u have 2 battery's with u . u wanna connect them in series then
one of the positive end is taken +ve terminal and the another end of the same battery must be connected to the +ive end of the another battery and then take the -ve terminal from the another end of the second battery
When was an inexpensive portable ventilator invented?
Matthew Callaghan, inventor of the OneBreath portable ventilator. He began developping the device four years ago, after realizing that logistically, since ninety-five percent of the ventilators in the U.S. are already in use at any given time, if many people became ill at once (say due to a flu pandemic), medical professionals would be forced to make some very difficult decisions. Plus, to buy new state-of-the-art models, it would cost hospitals anywhere from three to forty thousand dollars.
Where multi-layer PCB is used?
Multi layer pcb is modern pcb which has more than two layers. it is used in those devices where the circuit is more complex and it should be fabricate on small area of pcb. the examples are latest computer microprocessor and VLSI digital systems.
Why do electronics stop working when they get wet?
Either by corrosion or parts short out in the water.
Can you replace metal shield of co-axial cable?
Not easily. You can put a new coax end on the cable though and that should solve your problem.
You can do it the hard way and somehow ground the metal shield that is left on the cable as that is the main function of the shield. (but not the only)
What is the difference between 13.56mhz and 125khz?
There are at least three separate answers depending on what is really being asked.
The mathematical "difference" between 13.56 MHz (13,560,000 Hertz) and 125 KHz (125,000 Hertz) can be found by subtracting the smaller value from the larger. The answer is 13.435 MHz (13,435,000 Hertz).
The "obvious" difference between these two values is that 13.56 MHz is a much higher frequency measurement than the relatively slower 125 KHz measurement.
An "industrial application" difference is that the higher frequency, 13.56 MHz is useful in radio communications while the lower frequency (125 KHz) may be useful in Ultrasound applications. The electromagnetic qualities of the frequencies themselves determine their most useful applications.
electronic door lock is a device which is used for door locking . it will require password for opening it. for example if you purchase and install it than you need to enter some confidential password to open your door without password device will not active and keeps door shut.
What sensors are used on water rides?
Do you mean that sees if a person can go? If so, google Launch Logic and see the first hit.
What household items have leds?
LEDs make light, so some lights, usually outdoor ones, and some new TVs are LED backlit. Also most computer LCD screens are LED based. There are some more though.
IC's which starts from 7 are most of them are digital ic's . not all the IC's starts with 7 for example LM380 audio IC CTC810 audio amplifier ic
and lm317 voltage regulator ic ,NE555 timer ic, 4017 counter and so other.
there are no fact behind them .

What does piezo-electronic effect mean?
Piezo electric effect says that-
"If you applied mechanical vibration on the surface of crystal than the voltage will generate on the another surface and vice versa is also true."it is called piezo electric effect.
I'm guessing you didn't buy this new.
The drier should be supplied with a new overlay panel OR the overlay will be under the now upside down panel - if it's underneath be warned - you only get one chance as the old one won't go back on
