Never regard them as just decorations of a PCB board An advanced circuit board won&#39t be able to give its functionality until components are mounted on it A PCB with components mounted on is called an assembled PCB and the manufacturing process is called PCB assembly or PCBA for short The copper lines on bare board called traces electrically link connectors and components to each other They run signals between these features allowing the circuit board to function in a specifically designed way These functions range from the simple to the complex and yet the size of PCBs can be smaller than a thumbnail Solder mask On top of the copper layer is the solder mask which gives each PCB its characteristic green color It insulates copper traces from unintentionally contacting other conductive materials which could result in a short The solder in other words keeps everything in its place Holes in the solder mask are where solder is applied to attach components to the board Solder mask is a vital step for smooth manufacturing of PCBA since it stops soldering from taking place on unwanted parts with shorts avoided Silkscreen A white silkscreen is the final layer on a PCB board This layer adds labels to the PCB in the form of characters and symbols This helps indicate the function of each component on the board These materials and components remain largely the same across all PCBs with the exception of the substrate The substrate material of a PCB changes according to the specific qualities such as cost and bendability each designer is looking for in their finished product The three primary PCB types include Rigid PCB The most common type of PCB base is a rigid one that accounts for majority of PCBAs The solid core of a rigid PCB gives the board rigidity and thickness These inflexible PCB bases consist of a few different materials The most common is fiberglass otherwise designated as \\”FR4\\” Less expensive PCBs are made with materials like epoxies or phenolics though these are less durable than FR4 Automatic Optical Inspection Automatic optical inspection is a more appropriate inspection method for larger batches of PCBAs An automatic optical inspection machine also known as an AOI machine uses a series of highpowered cameras to \\”see\\” PCBs These cameras are arranged at different angles to view solder connections Different quality solder connections reflect light in different ways allowing the AOI to recognize a lowerquality solder The AOI does this at a very high speed allowing it to process a high quantity of PCBs in a relatively short time Flexible PCB Flexible PCBs offer a bit more pliability than their more rigid counterparts The material of these PCBs tends to be a bendable hightemperature plastic like Kapton Metal Core PCB These boards are yet another alternative to the typical FR4 board Made with a metal core these boards tend to spread heat more efficiently than others This helps dissipate heat and protect more heatsensitive board components Surface Mount Technology Sensitive components some very small such as resistors or diodes are placed automatically onto the surface of board This is called SMD assembly for surface mount device Surface mount technology can be applied on small size components and integrated circuits (ICs) For example PCBCart is capable of mounting package with min size 01005 which is even smaller than the size of a pencil point A few preparatory steps have to happen before real PCBA process even begins This helps PCB manufacturers assess the functionality of a PCB design and primarily includes a DFM check Most companies specializing in PCB assembly need the design file of the PCB to start out along with any other design notes and specific requirements This is so the PCB assembly company can check the PCB file for any issues that may affect the PCB&#39s functionality or manufacturability This is a design for manufacturability check or DFM check for short The DFM check looks at all the design specifications of a PCB Specifically this check looks for any missing redundant or potentially problematic features Any of these issues may severely and negatively influence the functionality of the final project For example one common PCB design flaw is leaving too little spacing between PCB components This can result in shorts and other malfunctions The first step of PCB assembly is applying a solder paste to the board This process is like screenprinting a shirt except instead of a mask a thin stainlesssteel stencil is placed over the PCB This allows assemblers to apply solder paste only to certain parts of the wouldbe PCB These parts are where components will sit in the finished PCB The solder paste itself is a greyish substance consisting of tiny balls of metal also known as solder The composition of these tiny metal balls is 965% tin 3% silver and 05% copper The solder paste mixes solder with a flux which is a chemical designed help the solder melt and bond to a surface Solder paste appears as a grey paste and must be applied to the board at exactly the right places and in precisely the right amounts The device starts the pick and place process by picking up a PCB board with a vacuum grip and moving it to the pick and place station The robot then orients the PCB at the station and begins applying the SMTs to the PCB surface These components are placed on top of the soldering paste in preprogrammed locations Once the solder paste and surface mount components are all in place they need to remain there This means the solder paste needs to solidify adhering components to the board PCB assembly accomplishes this through a process called \\”reflow\\” After the pick and place process concludes the PCB board is transferred to a conveyor belt This conveyor belt moves through a large reflow oven which is somewhat like a commercial pizza oven This oven consists of a series of heaters which gradually heat the board to temperatures around 250 degrees Celsius or 480 degrees Fahrenheit This is hot enough to melt the solder in the solder paste Once the solder melts the PCB continues to move through the oven It passes through a series of cooler heaters which allows the melted solder to cool and solidify in a controlled manner This creates a permanent solder joint to connect the SMDs to the PCB Many PCBAs require special consideration during reflow especially for twosided PCB Assembly Twosided PCB assembly need stenciling and reflowing each side separately First the side with fewer and smaller parts is stenciled placed and reflowed followed by the other side Checking for these errors and misalignments can involve one of several different inspection methods The most common inspection methods include Such inspections can occur regularly after the reflow process to identify any potential problems These regular checks can ensure that errors are found and fixed as soon as possible which helps both the manufacturer and the designer save time labor and materials Depending on the type of board under PCBA the board may include a variety of components beyond the usual SMDs These include plated throughhole components or PTH components Manual Soldering Manual throughhole insertion is a straightforward process Typically one person at a single station will be tasked with inserting one component into a designated PTH Once they&#39re finished the board is transferred to the next station where another person is working on inserting a different component The cycle continues for each PTH that needs to be outfitted This can be a lengthy process depending on how many PTH components need to be inserted during one cycle of PCBA Most companies specifically try to avoid designing with PTH components for this very purpose but PTH components are still common among PCB designs Wave Soldering Wave soldering is the automated version of manual soldering but involves a very different process Once the PTH component is put in place the board is put on yet another conveyor belt This time the conveyor belt runs through a specialized oven where a wave of molten solder washes over the bottom of the board This solders all of the pins on the bottom of the board at once This kind of soldering is nearly impossible for doublesided PCBs as soldering the entire PCB side would render any delicate electronic components useless.
