Before you send your board layout to PCB manufacturing, you should always check your board for errors. There is always a chance of errors when you design a board. Very often there are mistakes on a board. And very often you don’t discover it before you have manufactured the circuit board and are trying to troubleshoot it. [Read more…]
This is my step-by-step guide to schematic drawing in Eagle. Let us say we find the circuit above interesting and want to build a real electronic circuit out of it to test in the real world. The first step is [Read more…]
To be able to read schematics you must know the schematic symbols. Here is an overview of the most used symbols in circuit diagrams. [Read more…]
You don’t need fancy equipment to do SMD soldering at home. You can easily do it using a soldering iron.
SMD stands for Surface Mount Device and they are components that you solder on the surface of a circuit board.
Let me guide you through how to do SMD soldering with a soldering iron.
To know how to desolder a solder joint is maybe just as important as knowing how to solder.
Sometimes you need to make a correction to your electronic circuit. Maybe you soldered a diode in the wrong direction or maybe two of your pads have accidentally been connected by some extra solder.
In these cases you need to know desoldering. [Read more…]
