When designing PCBs, it is evident that the routing process is indispensable. The rationality of the routing not only determines the aesthetics of the PCB and its production costs but also reflects the performance of the circuit and its heat dissipation capabilities, as well as whether the performance of the components can be optimized. This … Read more
In microcontroller development, we often need to hand over the designed PCB files to the factory for production. Recently, one of our engineers encountered a troubling issue, as the PCB board lacked Mark points, resulting in deductions from the SMT factory. Today, we will discuss this topic: how important are Mark points in SMT processing? … Read more
