Pcbnet.com not only specialized in making quality printed circuit boards with our state of the art equipment, we are also up to our customer’s satisfaction to establish a long-term relationship with them. We want our customers to get the product that will work best for their designated application. If you are new to electronics designing or you want to refresh your mind about the different kinds of PCB, let us help you with that.
A PCB is a fundamental part of electronics. With printed circuit board, you will be able to connect various components to each other. PCB will allow power and signals to be routed between the components. It consists of different layers of materials. The base of the board is made of a material that does not conduct electricity, which is called substrate. Another layer of material, such as copper, is set on the surface where the electricity shall go.
The components are to be attached using metals to conduct electricity. Circuit boards are common in computers, mobile phones, radios and televisions.
Single Sided PCB
Our single-sided PCBs are the cheapest because they are also the simplest to manufacture. They only have one conductive layer since they are only designated for low density designs. We use copper as the conductive layer. For the rigid base, FR4 or fiberglass is readily available. FR4 is an excellent choice for a wide variety of applications due to its up to par thermal, mechanical, and electrical components. However, you can always request for exotic materials like polyimides. We have suppliers in the country and overseas so pcbnet.com could provide special PCBs for you.
To assemble a single sided PCB, we can do through hole or surface mount component. We attach thin wires to each of the component when using through hole technology. We also drill small holes in the substrate and then, pushed the wires inside these holes. Finally, we solder the wirings to the circuit’s connection pads on the opposite side.
Surface mount technology is more innovative. We use stubby L-shaped or J-shaped legs and attach each to the electronic components. To attach them to the board, we apply a solder paste which is a combination of glue, solder, and flux. To reflow or melt the solder, we put them on a state of the art oven. Once it has reflowed, we can say that the final connection is complete. Although this second method requires more careful attention, it eliminates the amount of work needed for through hole technology. We can also add a solder resist and idents for your single sided printed circuit boards.
Double Sided PCB
When you have too much components that single sided PCB can no longer handle, pcbnet.com will advise you to resort to double sided PCB. In this type, we use two conductive layers of a rigid base. The two conductive layers may be connected with each other using a copper plated hole.
Double sided PCBs allow routing around each of the components. The connection will jump between the top and bottom layer through a via. Via, which stands for vertical interconnect access, is a pathway that allows connection to go through the plane of adjacent layers.
Because of the features of double sided PCBs, you can be flexible with your circuits’ designs. You will also be able to increase circuit densities. Our double sided PCBs are also extremely affordable. Both through hole technology and surface mount technology can be applied to this type.
The last one among the three main types of printed circuit boards is multi-layered. We use several layers of substrate that are separated by layers of insulation. Commonly, multi-layered PCBs have four to ten layers. But for our clients who need PCBs for a large production, we can make up to fifty layers of substrate. The complex and dense the circuit design is, the more layers you will need.
To simplify the circuit pattern, we connect the components through plated holes that were drilled to their designated circuit layer. In some cases, pcbnet.com also use extra layers as power planes to supply power to the circuit and to lower EMI or electromagnetic interference levels brought by the circuit designs. This method is necessary for high-powered designs.
With our many years in the industry, you can be assured that we can supply you PCBs of any type in the quickest possible time. Our advancement in PCB assembly is also favorable to our clients.
