What is Electronic test/probe test

Combine Automatic optical alignment system and the traditional flying needle machine together,with the help of image-processing software and flying-pin-only cameras, flying probe test is easier and more accurate.The electronic test for circuit boards is performed after manufactured. All the pcb manufactured by PCBWay must be checked with flying probe test. The layout is analysed according to the pcb file for short circuits and interruptions. This is important because only the E-test detects inco...

Comparison of several PCB surface finish types

PCB surface finish is a coating between a component and a bare board PCB. It is applied for two basic reasons: to ensure solderability, and to protect exposed copper circuitry. As there are many types of surface finishes,selecting the right one is no easy task, especially as surface mounts have become more complex and regulations such as RoHS and WEEE have changed industry standards.HASL(Hot Air Solder Leveling) / Lead Free HASLHASL is the predominant surface finish used in the industry. The pro...

Flexible PCB vs Rigid PCB

Flexible PCB (also variously referred to around the globe as flex circuits, flexible printed circuit boards, flex print, flexi-circuits) are members of electronic and interconnection family. They consist of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits. The technology has been used for interconnecting electronic devices since the 1950s in one form or another. It is now one of ...

What is Rigid-Flex PCB?

Rigid-Flex printed circuit boards are boards using a combination of flexible and rigid board technologies in an application. Most rigid flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally, depending upon the design of the application. The flexible substrates are designed to be in a constant state of flex and are usually formed into the flexed curve during manufacturing or installation.Rigid-Flex designs are more ...

Aluminum PCB vs FR-4 PCB

What is Aluminum PCB?Among all Metal core PCBs, Aluminum PCBs is the most common type - the base material consists of aluminum core with standard FR4. It features a thermal clad layer that dissipates heat in a highly efficient manner, while cooling components and increasing the overall performance of the products. Currently, Aluminum Backed PCBs is regarded as the solution to high power and tight tolerance applications. Price ComparesFR-4 PCB is a very conventional PCB type of electronic industr...

What are Plated Half-Holes(Castellated Holes)

Plated half holes(castellated holes)are holes that made off the edge of the boards plated withcopper using a specialized process. It is predominantly used for board-on-board connections, mostly where two printed circuit boards with different technologies are combined.Through connecting the PCBs together directly, the whole system is considerably thinner than a comparable connection with multi-pin connectors. The plated edges are also useful in producing mini PCB modules. Plated half holes are av...

What is the meaning of Glass Transition Temperature (Tg)

The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from a hard, glassy material to a soft, rubbery material.Circuit board material must flame-resistant, it can’t be burned at a certain temperature and only be soften. The temperature point is called the glass transition temperature (Tg).The higher Tg point means higher temperature requirement during lamination. And the boards will be hard and crisp...

What is Solder Mask Bridge and Solder Mask Opening on a PCB

1.Solder Mask Bridge: The oil between two pins of component is solder mask bridge, generally refers to intensive IC pin (check the below picture). If the distance of pin is too small, it will be recommended to cancel the solder mask bridge and take advantage of solder mask opening technology.2.Solder Mask Openings: the place without solder mask calls solder mask opening3.PCBWay can accept the minimum distance between IC pins is 0.2mm (check the below picture), if the distance less than 0.2mm, we...

Why is there additional cost for panel PCBs?

The reason why the cost of panel pcb will increase is it lower substrate utilization.PCB substrate is a fixed size, when your board is small, manufacturers can make panel by themselves, so the rate of substrate utilization is high and less waste area, the cost will decrease.But if your design is panel, the manufacturer must treat your panel as the basic unit, so the rate of substrate utilization is low and the cost will rise. And it needs V-cut and route.And many different designs on the same b...

Blind vias and Buried Vias

Blind and buried vias are only available on boards with at least four layers. Unlike regular vias on a two layer board which connect the two surface layers, buried and blind vias connect the inner layers with either other adjacent inner layers or adjacent surface layers.Blind Vias: Connects an inner layer with the adjacent surface layer, they are only visible on one side of the boards and so are called 'blind' vias. Buried Vias: Connects two adjacent inner copper layers. They are not vis...

What should I do if my PCB does not require solder mask?

Unlike the copper layer, the solder mask layer is negative. This means a solid object in the layer corresponds to a hole, or opening in the solder mask layer (an area without solder mask covering). Therefore, for a board that requires the surface to be fully covered with solder mask, the solder mask layer should look like this, an empty outline of the boards. For boards that do not require solder mask at all (exposed traces and bare FR-4 substrate material), then the solder mask layer should be ...
