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
When you finish your PCB design and PCB fabrication, the next step is to perform PCB assembly and final integrity electronic project testing. PCB assembly is a very critical work in the whole of electronics projects manufacturing process. There would be a big cost and time lost if there is an anti-repair failure form the … Continued
Silkscreen is one of important compositions to a complete PCB board fabrication, especially it’s high importance to PCB assembly. What is the PCB silkscreen? The silkscreen is a layer of ink printed on the bare circuit board used to identify the electronic components, Rev. no.#,test points, marks, logos, symbols, etc. Normally it is printed on … Continued
To perform the correct PCB production of your printed circuit board, it must have a label in the copper of the PCB top and PCB bottom layer, for multilayer PCB additionally on the inner layers. In China, it was once common practice to label the Component Side (assembly side) with BS, and the solder side … Continued
A symmetric copper distribution (copper balance) on the circuit board is very important, because asymmetric copperleads to bow and twist effects in PCB fabrication process,and finally will affect the soldering quality of components in PCB assembly process. This warping of the form is caused by thermal loads in the circuit board, such as those caused … Continued
Optimize the global manufacturing cost of PCB and PCBA prototypes When it comes to start a PCB design for prototypes, Most circuit board designers like to put various PCBs (the same layer count and stack up but with difference in size, shape etc) into one panel to optimize the cost in the PCB fabrication and … Continued
