This film is blue light sensitive so all the lights into the This machine does this automatically or sometime done this process manually.
Then panel is first coated with a layer of photosensitiveįilm, the photoresist, which is hot-rolled onto the copper. To enter into this room, we need to put on a special type of Anti-Static Clothes, and we need to pass through a dust cleaning chamber. This process took about 40 min of time, and then the board automatically goes to another room for next step.

After that the board goes through a series of process, where copper is plated up to a thickness, depending on the requiredįinal finish for the panel. This is a multi-stage process and everything is controlled by computer to ensure about 1-micron thick copper has deposited over the walls of the hole.īefore the electroplating, the PCBs need to be micro-etched to roughen the surface of the boards, strengthen the bonding force of copper ions, and remove the residue and oxide on theīoards surface to avoid contamination of the copper plating tank. The panels are carried through a series of chemical and The operator loads the panels onto the flight bars, the panels themselves act as cathodes for electroplating. This is a air driven drill which can rotate up to 150,000 revolutions per minute, the high speed drills makes the hole walls cleaner.Īfter that the corners are trimmed to make it rounded, then the surface is cleaned and the machines automatically smooth the edges of the boards.Īs the Board has drilled for making connection between top and bottom layer but the middle layer is nonconductive fiber glass, so to make connection between top and bottom layer the boardĬomes for electroplating. The correct size, and then loads it into the drill head. The machine selects the drill to use from the drill rack and checks that it is Those machines areĬomputer-controlled, after selecting the right drill program the machine starts working, Drill change is fully automatic. The operator takes a MDF board as exit material, then he loads one or more PCB panels and place it on the machine, and finally adds a sheet of aluminum as entry foil. For connecting the leaded components and for the via holes that link the copper layers together. This table is designed to help you understand if our capabilities are a match for your design.It willĪlso allow you to plan ahead and create your design within these capabilities so that you can be sure we can produce your PCB.Īfter cutting the boards, they come to the drilling room. In the table below is a key PCB capability list of NextPCB’s printed circuit board manufacturing. Handle through the factory thus the production cost also decreases. After checking several circuits, they combine them on a large production panel which is much more efficient to

After we make a PCB order in NextPCB website, first engineers inspect our uploaded PCB file, it conducts a DFM review by checking the trace widths, the space between the traces, hole sizeĮtc and ensure the design is error free and fits within manufacturing capabilities.
