Basic Soldering techniques for freshers/newbie

Soldering is the basic process required in every electronics industry and an individual should have knowledge of soldering if he is an electronics engineer.

Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint, the filler metal having a lower melting point than the work piece. Soldering differs from welding in that soldering does not involve melting the work pieces.

I don't think you should go deep in theory related to soldering but you should know about the basic equipment required to soldering.

Equipment:

1. Solder Iron

2. Solder Wire

It melts and solder the components on PCB

3. Solder Flux

It removes the impurity from the solder wire during melting. it lowers the melting point of solder wire

4. General Purpose PCB

It is a General Purpose PCB on which objects are mounted.

Applications:

- Soldering is used in plumbing, in electronics and metalwork from flashing to jewelry.

- Soldering provides reasonably permanent but reversible connections between copper pipes in plumbing systems as well as joints in sheet metal objects such as food cans, roof flashing, rain gutters and automobile radiators.

- Jewelry components, machine tools and some refrigeration and plumbing components are often assembled and repaired by the higher temperature silver soldering process. Small mechanical parts are often soldered or brazed as well. Soldering is also used to join lead came and copper foil in stained glass work. It can also be used as a semi-permanent patch for a leak in a container or cooking vessel.

- Electronic soldering connects electrical wiring and electronic components to printed circuit boards (PCBs).

How to Remove Solder

Precautions while doing soldering:

1. Hold tightly Solder iron while soldering as the temperature of solder iron is very high can burn your skin if touched.

2. Use flux for better soldering. Take flux and slightly rub on the pins that you are going to mount.

3. Do not put heated solder iron anywhere. Keep it in its case provided.

4. Use slight use of Solder wire while melting on components to avoid shorting between the pins.

Buzzer interface with 8051 microcontroller

Buzzer is a electronic device that converts the electronic signal into buzzing noise, that is applied to it. It can be used as electronic bell or as quiz buzzer in many applications around us. Here, i world like to discuss the interfacing of a small buzzer with 8051 microcontroller and how different projects can be constructed. Buzzer Interfacing: This project shows the interface with AT89S52 microcontroller to a buzzer. When a push button is pressed, the buzzer will get ON and OFF ( number of times set in the code ) and then stops. Circuit Diagram: - The port P1 of the microcontroller is connected to buzzer. This type of connection is possible, if the current requirements of the buzzer is not more than 20mA. The output is in current source mode so that buzzer will turn ON when the output of the port is logic LOW. Switch is connected to port P3 which remains at logic HIGH by pull up resistor. Code: #include "REG52.h" #define buz P1 sbit SW=P3^0; long i...

Comparison Chart Between 8051, 8052, 8031and 8751

8051 is a popular 8-bit microcontroller and has been used in many applications since Intel introduced it. Many 8051 architecture are produced by Triscend, Intel, Atmel, Philips, Infineon (Siemens), ISSI, and Max Corp. Today, 8051 microcontrollers may not be popular but, the 8051 architecture is still popular and employed in thousands of embedded applications. This 8-bit architecture has been different segments such as 8052, 8051, 8751 and 8031 . 8052 is the super-set of 8051 and 8031 is the memory-less microcontroller hence, it has interfaced with external ROM. Whereas, 8751 chip has only 4Kbytes of on chip UV-EPROM. Everyone knows about the general 40-pin microcontroller i.e. 8051 introduced by Intel in 1980s and consists of serial communication pins, Timer, Interrupts, RAM, ROM. It has 4 ports and each port has 8 pins, total 32 pins and other 8 pins for other purposes. 8052 is the super-set of 8051 that consists of 8K bytes of internal RAM (4K in 8051), 256 by...

Different ways to generate delays in 8051

The delay length in 8051 microcontroller depends on three factors: The crystal frequency the number of clock per machine the C compiler. The original 8051 used 1/12 of the crystal oscillator frequency as one machine cycle. In other words, each machine cycle is equal to 12 clocks period of the crystal frequency connected to X1-X2 pins of 8051. To speed up the 8051, many recent versions of the 8051 have reduced the number of clocks per machine cycle from 12 to four, or even one. The frequency for the timer is always 1/12th the frequency of the crystal attached to the 8051, regardless of the 8051 version. In other words, AT89C51, DS5000, and DS89C4x0 the duration of the time to execute an instruction varies, but they all use 1/12th of the crystal's oscillator frequency for the clock source. 8051 has two different ways to generate time delay using C programming, regardless of 8051 version. The first method is simply using Loop program function in which Delay() funct...
