- 2026/1/18PCB layout development for online testing systemsIn-circuit testing (ICT) is a sophisticated and systematic PCB verification method that allows for the testing of individual components and circuit nodes while the circuit board is fully assembled with all electronic components. Unlike functional testing, which evaluates the overall system behavior and output response, ICT measures fundamental electrical parameters such as resistance, capacitance, inductance, and semiconductor junction characteristics by contacting specific test points with probes.Learn more
- 2026/1/18PCB reverse engineering precautions and methodsThe accuracy of PCB reverse engineering depends on two factors: the precision of the software and the precision of the original image. For software precision, using 32-bit floating-point representation means there are virtually no precision limitations. Therefore, the most crucial factor is the precision of the original scanned image. To illustrate, a 1-megapixel photo is suitable for printing a 5-inch print, but a 20-inch print would be unreadable. Similarly, for circuit boards requiring high precision, a higher DPI must be selected during scanning to achieve a very high-precision PCB layout.Learn more
- 2026/1/18What are the steps involved in assembling a circuit board?To better understand the PCB assembly process, you must have a clear understanding of the most basic unit of a PCB – the base. The base of a PCB consists of the following layers.Learn more
