A conformal coating is a type of thin polymeric film applied to a PCB (printed circuit board) by machine or by manual in order to have the electronic PCB boards and its components to be protected from the environment and corrosion. Normally, the film is applied at typical thickness of 25-250µm and ‘conforms’ to the shape of … Continued
When it comes to talk about PCBs (printed circuit boards), nearly it is impossible to get a fixed answer that how many layers you can have. Some IC test mainboards even have nearly a hundred layers in their construction; but, the most consuming electronic products only have common layered PCBs usually from two to four … Continued
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
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
Within any simple electronic devices we used nowadays, there is a PCB (printed circuit board) drive it to run. The PCB is the core component of the electronic devices, whether it is a consume product such as battery charger, the communication equipment such as mobile phone, or transportation tool such as vehicle, even it is … Continued
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
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
When you finish your PCB layout design and then you can send it to PCB manufacturers who provide custom circuit board service to have your PCB board manufactured. And, you can plan your final electronic PCB assembly after custom circuit board printing process finished. The engineering flow process before manufacturing electronic PCB Normally, the designer … Continued
Introduction PCB stackup is an important factor in determinate the EMC (Electron-Magnetic compatibility) of a electronic product. When we talk about the PCB stack up, we are referring a multi-layer printed circuit board ). A good stack-up can be very helpful in reducing the radiation and the electromagnetic interference from loops on the PCB. On … Continued
Nowadays,PCB manufacturing is hot competitive, and there is lot of worldwide manufacturing capacity factories for any technology challenge circuit boards. If you’re ready to look for a professional PCB manufacturer for your next project, more or less it can be difficult to determine who is the best option to produce your circuit board. Different PCB fabricators … Continued
