In 1936, the first printed circuit board (PCB) was developed by Paul Eisle. However it wasn’t until the 1950s when the U.S. Defense industry began integrating PCBs within their bomb detonator systems that printed circuit boards found wide application. PCBs are now utilized in almost all manufactured products like, automobiles, cellular telephones, personal computers, among others.

An Overview in the PCB Fabrication Processes

PCBs are initially fabricated with the use of 2 kinds of software. Computer Aided Design (CAD) software is used to design the electronic schematic of the circuit to be produced. After the schematic is made, Computer Aided Manufacturing (CAM) software is used by engineers to produce the Ultrafast PCB Prototype.

After the PCB prototype is designed, the initial step in the fabrication process is always to pick the material in the printed circuit board. There are many different types of PCB materials available, but the popular ones, based on the application and a customer’s requirements, include: Alumina, Arlon, Bakelite, CEM1, CEM5, Ceramic, FR1, FR4, FR4 High Temperature, GeTek, Nelco, Polyimide and Rogers.The design and style requirement dictates the proportions of the PCB (I.e., length, width and thickness).

Right after the material has been selected, the initial process is to apply a coating of copper towards the entire board. The circuit layout will likely then be printed on the board with a photosensitive process. Then, a picture engraving process will be used to ensure that each of the copper that is not portion of the circuit layout will likely be etched out or removed from the board. The resulting copper produces the traces or tracks in the Fast PCB Quote. For connecting the circuit traces, two processes are employed. A mechanical milling process will use CNC machines to eliminate the unnecessary copper through the board. Then, an etch-resistant, silk-screen, printing process is used to protect the regions where traces must exist.

At this particular point inside the PCB fabrication process, the PCB board contains copper traces without any circuit components. To mount the ingredients, holes must be drilled on the points where the electrical and electronics parts are placed on the board. The holes are drilled with either lasers or a special kind of drill bit made of Tungsten Carbide. When the holes are drilled, hollow rivets are inserted into them or these are coated by an electroplating process, which creates the electrical link between the layers from the board. A masking material will be applied to coat the whole PCB with the exception of the pads and the holes. There are many types of masking material such as, lead solder, lead free solder, OSP (Entek), deep/hard gold (electrolytic nickel gold), immersion gold (electroless nickel gold – ENIG), wire bondable gold (99.99% pure gold), immersion silver, flash gold, immersion tin (white tin), carbon ink, and SN 100CL, an alloy of tin, copper, and nickel. The final part of the PCB fabrication process is always to screen print the board so labels and the legend appear at their proper locations.

Testing the caliber of the PCB Board

Before placing the electrical and electronic components on the PCB, the board needs to be tested to confirm its functionality. In general, there are two varieties of malfunctions that can result in a faulty PCB: a quick or even an open. A “short” is really a connection between several circuit points which should not exist. An “open” is a point in which a connection should exist but does not. These faults must qhzwxo corrected before the PCB is assembled. Unfortunately, some PCB manufacturers usually do not test their boards before they are shipped, which can lead to problems on the customer’s location. So, quality testing is a vital process of the Ultrafast PCB Produce. Testing ensures the PCB boards are in proper working condition before component placement.
