How to design the safety spacing of PCB? Electricity-related safety spacing

How to design the safety spacing of PCB?                                                                          Electricity-related safety spacing 1. Spacing between circuit. For the processing capacity, the minimum spacing between wires should be no less than 4mil. The mini line spacing is the... Read More

Detail PCB through hole, back drilling points

 Through hole design of HDI PCB In high speed PCB design, multi-layer PCB is often used, and through hole is an important factor in multi-layer PCB design. The through hole in PCB is mainly composed of three parts: hole, welding pad area around hole and POWER layer isolation area. Next, we will u... Read More

16 kinds of PCB weld defects

Every day has learned a little of PCB and I believe I can become more and more professional in my work. Today, I want to introduce 16 kinds of PCB weld defects from appearance characteristics, hazards, causes.   1.Pseudo Soldering Appearance characteristics: there is an obvious black boundary bet...

PCB Industry Terms and Definitions– Power Integrity

Power integrity (PI) Power Integrality, referred to as PI, is to confirm whether the voltage and current of Power source and destination meet the requirements. Power integrity remains one of the biggest challenges in high-speed PCB design. The level of power integrity includes chip level, chip pa... Read More

PCB plate percolation occurs during dry film plating

The reason for the plating, it shows that the dry film and copper foil plate bonding is not strong, so that the plating solution deep, resulting in the “negative phase” part of the coating thickening, most PCB manufacturers are caused by the following reasons: 1. High or low exposure ... Read More

Metal substrate plug hole technology

     With the rapid development of electronic products to light, thin, small, high-density, multi-functional and microelectronic integration technology, the volume of electronic components and printed circuit boards is also shrinking exponentially, and the assembly density is increasing.In order ...

Ways to find defective PCB board

By Measuring Voltage   The first thing to confirm is whether the voltage of each chip power pin is normal or not, then check whether the various reference voltage is normal or not, in addition to the point of the working voltage. For example, a typical silicon triode has a BE junction voltage o...
