Drilling For the multi-layer circuit board transmit signals between layers holes need to be drilled or lasered into to create vias that connect the layers. Drilling is different based on the kind of via that is being utilized and is usually performed using a set of 2-3 panels at one time. The final product will typically be five millimeters larger than the finished product because these holes are coated with copper to send electrical signals via the Electroless Copper Deposition. Hidden and blind vias need to be constructed prior to that process of laminating. Incorporating these vias to your PCB design may raise the price due to additional steps to be followed. Electroless Copper Deposition & Dry Film Outer Layer After holes are made in the substrate, any excess resin and debris is cleaned by using mechanical and chemical processes. After that, a fine layer of copper is then deposited across all exposed surfaces of the panel, forming an aluminum foundation for an electroplating. Like the development/etch/strip method that was previously used, dry film is sprayed onto the outside on the panel. It is exposed to direct laser imaging and leaves a conductive pattern. Electroplating, Stripping, and Etching With the pattern that conducts and drill holes visible the panel is then set in an electroplating bath of copper that is enriched with sulfuric acid, as well as copper sulfurate. When an electrical charge is added to this bath the bath, copper is deposited on the surface that conducts electricity on the board in an average thickness of 1 millimeter. The plate is removed and placed in an etching bath with tin for use to act as an etching barrier.   After plating is complete The drying film will be removed, and the exposed copper that was not covered by tin, is removed leaving only the trace pads, as well as other designs that are left on the plates. The remainder of the tin is chemically removed and only the copper remains in the precise zones. At this moment your printed circuit board has been put together, but it's still not yet ready to be assembled. Solder Mask, Silkscreen, and Surface Finish Prior to moving on towards step 3: PCB assembly stage The printed circuit board is secured with an solder mask that has the same UV exposure as at the time of the photoresist. This gives the printed circuit board its distinctive green hue, but other colors are also possible. Solder masks are an extremely small layer of polymer which shields copper traces printed on the board from the oxidation. It also blocks solder bridges that are created when an unintentional connects two conductors, which can compromise the function of a circuit printed board. Solder mask color may be selected at this point However, the majority of manufacturers choose green as it is helpful in detecting defects thanks to its bright contrast and visibility to trace, which is essential in the PCB prototyping phase. The color of the Solder mask doesn't typically alter the function of a PCB, however the darker shades are more prone to heat absorption and therefore not suitable for applications that require high temperatures.. After the solder mask is been applied, the component reference designations and other board markings are screened onto the circuit board. The silkscreened mask and solder ink cure by baking the circuit board inside an oven. The final step is to apply a surface polish is applied over metal surfaces that are not covered by the mask for solder. This shields the metal and assists in the soldering process in the PCB assembly process.   Assembly Preparation, Inspection, and Testing With the PC fabrication process completed The boards are then subjected to an array of checks and tests to verify their performance prior to being assembled or shipped. Automated testing equipment is used to identify any imperfections that might cause problems for the board. Any PCBs which fail the requirements are rejected.
