PCB Without Mark Points: The Critical SMT 'Lifeline' Engineers Must Be Aware Of

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
