PROBLEM TO BE SOLVED: To provide a circuit board that reduces variations in thickness of a thin-film conductor layer.SOLUTION: A circuit board 4 comprises: a ceramic substrate part 1 that has a ceramic substrate 11 and a circuit conductor 12; and a thin-film multilayer part 2 having a ...
How to Design a Circuit Board: An Introduction A common mistake of amateur layout designers is racing to get to the board level of design. It’s not hard to understand why: the board is the fun part of the design, where users play a 3D puzzle game trying to find the best-engineered ...
The same confidence is reflected during times when I need to test a circuit board. While there’s no steering wheel involved, I have other tools that help in identifying faults in the circuit. It can be a struggle but when you have a systematic test procedure you’re bound to locate the...
The question "How to read circuit boards" or "How to read schematics" often arises for beginners. Sometimes "What is this component" may also arise. These questions can be solved altogether in this article guiding how to read a circuit board and identify components. How to Read Circuit Boar...
Welding connection is a commonly used connection method between PCBs, usually divided into manual welding and automated welding. Manual welding usually requires the use of electric soldering iron and soldering tin. The circuit board components that need to be connected are heated by soldering iron to...
When you can't find plans, reading a circuit board is the only way to replicate or repair an old circuit. This can be a daunting and time-consuming task. Older circuit boards may contain unrecognizable parts that are no longer manufactured. Others may feature custom-integrated circuits that ...
To design a Printed Circuit Board (PCB), you need to draw holes, pads, and wires for your circuit. When you’re done drawing the board, you can either send the design to a manufacturer that will make it for you (it’s actually pretty cheap) – or you can etch it yourself at home...
1.When there is a large-scale integrated circuit on the circuit board to be repaired, pay attention to the reset problem. 2.It is best to put it back on the device before the test, turn it on repeatedly, try the shutdown device, and press the reset button several times. ...
Learning how to check circuit board components is easy. This is why we have explained the process. Fluid leakage, burned circuit components, power-related concerns, soldering errors, including connection shorts on PCBs are among the prevalent failures on the circuit boards. Smaller copper trace is...
Learn how to make a PCB with step-by-step guidance, from designing circuits to etching and assembling your custom boards.
