Today, we will not discuss PCB design. Everyone knows that “circuit short circuits” are problems that PCB manufacturers encounter almost daily, and they are relatively difficult to solve. The improvement of this issue directly relates to production costs and the qualification rate of finished products. The first step in improvement is inspection. Below, I will … Read more
1.1 Basic Recognition Mnemonics A circuit board can change in countless ways; the combination of components is key. Resistors and capacitors are the most common; understanding their symbols is essential. Resistance changes and capacitor leakage; remember the basic characteristics. Inductance and voltage changes can be checked; measure the PN junction of transistors. MOSFETs can be … Read more
When performing PCB soldering, we need to strictly control the entire soldering process to ensure the quality of the soldering. Below are the key considerations for PCB soldering. 1. After receiving the bare PCB, first conduct a visual inspection to check for issues such as short circuits or open circuits. Then familiarize yourself with the … Read more
1 Tools for Manual Soldering Any electronic product, from a rectifier made up of a few components to a computer system composed of thousands of parts, is constituted by basic electronic components and functions, connected according to circuit principles using specific techniques.Although there are various connection methods (e.g., wrapping, crimping, adhesive), the most widely used … Read more
