What is Soldering ? Soldering is a process in which two or more metal items are joined together by melting and then flowing a filler metal into the joint—the filler metal having a relatively low melting point. Soldering is used to form a permanent connection between electronic components. Things required for soldering Soldering iron Solder (Tin Lead) Flux (Soldering Paste)  Soldering Iron Stand  Tweezers  Hot Air gun required for SMD soldering Desoldering pump or Desolder Sucker    Let's check these into more details. Flux (Soldering paste) We call also flux as Flowing agent, Purifying agent and Cleaning agent. What are the chemicals used in the flux ? Sodium Carbonate Potash Borax Lead Sulphide   We Need this flux for two different usages.  Separate the metals solder the metas Flux is used for Oxidation and Impurities removal. Means when we are soldering it will remove the oxygen and the dusts from the soldering point. This will make your solderi...

The Winbond 25Q32 is a really cool part : high capacity (32 MBytes), very fast, good support for many standard instructions, supports wide bus modes... But it can be expensive depending on the application. Winbond 25Q32 is commonly used flash memory in the LED/LCD Tv's. Electricians in Sri Lanka call this with the different names such as  FLASH IC PROGRAMMABLE IC BIOS IC EEPROM IC EMMC IC SPI IC There are different series of IC's available in the market i'll mention few here 24 Series  25 Series  29 Series  Electricians mostly call this 24 Series only as Flash IC and the 25 series IC's called as EPROM/ SPI IC.  25 series is the one commonly used for LED or LCD TV's. SPI stands "Serial peripheral Interface" Serial peripheral means electronic device which can operate out of the microcontroller and which supports microcontroller functions. Also this is called as EPROM means "Erasable Programmable Read Only Memory". you can programme this with a ...
