Reliability Analysis of Hole Spacing in PCB Design

Leave a Comment / Blog / By

The production of single-sided or double-sided PCBs typically involves drilling non-conductive or conductive holes directly after the material is cut, while multi-layer boards are drilled after the lamination process. Holes are categorized based on their function, including component holes, tool holes, through holes (Vias), blind holes, and buried holes (blind and buried holes are a

Importance of PCB Layout about Electronic Components in PCBA

Leave a Comment / Blog / By

Proper installation of electronic components on the PCB is crucial to reducing soldering defects. When arranging electronic components, avoid areas with high deflection values and high internal stress. Distribute components evenly, especially those with high thermal conductivity. Avoid using oversized PCBs to prevent expansion and contraction. Poor PCB layout design can affect the PCB’s manufacturability and

How to avoid pitfalls in square slots and square holes of device pins

Leave a Comment / Blog / By

Introduction Nowadays, circuit boards use more SMD components than plug-in components, but for those electronic products with higher heat dissipation requirements, the performance of plug-in components will be better than that of SMD components. In addition, the external interface of the motherboard and the devices of the connector all use plug-in pins, such as USB,
