IntroductionThe V-CUT is the PCB manufacturer make a partition slot after build the PCB as the customers requirements. Most of the customers will choose to panelize printed circuit boards and split it by there own. The “V” partition line can facilitate the customer to split the panel.Consideration of V-CuttingThe reason why PCB manufacturers usually depanelize printed circuit board before shipping is that they have to consider multiple factors, such as increasing the production capability of SMT (surface mount) equipment and reducing the bottleneck of equipment operation. Second, the PCB manufacturer needs to balance the utilization rate of its board to reduce costs. Third, because of the different design of the printed circuit board, in the PCB manufacturing factory, it usually needs to go through many different processes.Most of the printed circuit boards are FR4 (epoxy-based) or aluminum-based, so it is not very realistic to use manual hands ...

Some electronics hobbyists may have known how to make a custom PCB in-house. However, do you know how do printed circuit boards manufacture in streamlines or factories?PCB manufacturing is more related to chemical and photo-logy than physics. Most PCB manufacturers adopt the dry film developing technique to print circuits into the boards. They also use chemical reactions to electroplate vias and holes on the PCBs.What is Printed Circuit Boards?A printed circuit board (PCB) is the board base for physically supporting and wiring the surface-mounted and socketed components in most electronics. In applications where fine conductive traces are needed, such as computers, PCBs are made by a photolithographic process, in a larger-scale version of the way conductive paths in processors are made.Electronic components are typically placed by the machine onto a finished PCB that has solder joints in place. The PCB bakes in a reflow oven to melt the solder, which joins the connections. Most PCBs...

Printed circuit board is derived from the PCB (Printed Circuit Board), or also known as PWB (Printed Wiring Board). After the 1960s, various electronic and electrical products have been manufactured using electroplated through-hole circuit boards with heat-resistant and high dimensional stability substrates, which have developed rapidly and are still the main resin substrates. As the semiconductor technology developing to high-density structure, the component density also increasing, which formed the trend of advanced PCB. History of Printed Circuit BoardThe concept of laminate circuit board design has existed since 1967, but it was not until 1990 when IBM released SLC technology that microvia technology became practical. Before that, the industry to the full through-hole board, multiple lamination board to build a high wiring density. Due to the rapid progress in materials, photosensitive, thermopolymer insulation materials have been on the market, microvia techn...

Manufacturers understand that there will be a lot of quality control and PCB testing involved in the PCB manufacture process. Many quality tests are done to guarantee that a design can be manufactured at scale and with good quality, although most of this happens behind the scenes and without the designers knowledge. During prototyping, other crucial tests, such as PCB functional testing and IC programming, are usually the responsibility of a designer, and these tests will be folded into production when producing at scale.Whatever degree of testing and inspection you require, its critical to identify the fundamental test requirements for your design and convey them to your manufacturer. Read our list of PCB testing requirements if this is your first time going from prototype to high-volume manufacturing so you know what to anticipate.PCB Testing In ManufacturingSeveral PCB testing processes are carried out during the fabrication and assembly process. These are used to evaluate the qu...

There are many technical differences between 5G cellular technology and previous mobile communications, and these differences will certainly affect the application and selection of PCBs and materials.5G applications are typically divided into sub-6 GHz bands and millimeter wave bands. Most of the initial deployments were based in the sub-6 GHz band; while, the majority of the deployments are in the sub-6 GHz band. With the development of millimeter wave systems, the millimeter wave band will be increasingly used in the future. 5G has the advantage of higher data rates and lower latency.The boom in 5G technology will enable enhanced mobile broadband (eMBB), massive Internet of Things (MMTC), and ultra-reliable low-latency communications (uRLLC). PCBs associated with 5G applications will have higher levels of integration and more functionality, thus requiring higher PCB design requirements and a broader portfolio of circuit materials.PCB heat management consideration5G technology ...
