In the electronics manufacturing industry, ionic contamination testing of PCBs (printed circuit boards) is a critical step in ensuring product quality. Ionic contamination refers to the residual charged ions on the PCB surface. These contaminants primarily originate from manufacturing processes such as soldering additives, cleaning chemicals, humidity control, electroplating, wave soldering, and reflow soldering. These…
For later component assembly,especially manual assembly,a PCB assembly drawing is usually drawn for component placement and positioning .At this time,the silkscreen position number shows its necessity. Friends who are new to PCB drawing must have experienced this operation.Manually adjusting the silkscreen position number of components one by one is very tedious and inefficient… Is there…
In actual research, we have summarized four main sources of interference:power supply noise,transmission line interference,coupling,and electromagnetic interference(EMI).By analyzing various interference issues in high-frequency pcbs and combining them with practical application,we have proposed effrctive solutions. 1.Power Supply Nosie In high-frequency circuits,power supply noise has a particularly significant impact on high-frequency signals.Therefore,a low-noise power supply is paramount.Here,a…
PCB Design Step 1: Preliminary Work for PCB Copying PCB Design Step 2: Create a Customized Footprint Library for Non-Standard Components It is recommended that you place all your drawn components into a dedicated design file for your own PCB library.
