PCB Design Factors Affecting PCB Assembly Processing

PCB assembly process is based on the production data of PCB design and specification of PCB fabrication. Excellent PCB design will facilitate subsequent PCB assembly processing, while incomplete design will affect the processing process and even affect the quality of the final PCB assembly product. So what are the PCB design factors that will affect … Continued

What is the PCB thermal dissipation and how to optimize it?

PCB thermal dissipation so important to make it’s electrical device works properly,but how to make the PCB more dexterous? (The electrical energy consumed by electronic equipment during operation, such as radio frequency power amplifiers, FPGA chips, and power products, some of is working needed, but most of which is converted into heat and dissipated) 1. … Continued

The difference of PCB Back Drilling and Controlled Depth Drilling

What is back drilling or controlled depth drilling in PCB? PCB Back drilling is one of the special controlled depth drilling (NPTH) in the loop of PCB manufacturing process. Normally, there will be various challenges in engineering and production when it comes to PCB design and printed circuit board manufacturing and one of them is … Continued

Must knows to heavy copper PCB and it’s manufacturers

What is the heavy copper PCB Usually, when out-layers or inner-layers of any printed circuit board are specified to use ≥2oz base copper foil, we call it heavy copper PCB (or thick copper PCB board). For final finished copper thickness (means base copper + plating copper) we normally follow customers’ requirements to do.But,if no specific … Continued
