The copper skin covered by the dry film is protected through the etching line, while the copper skin not protected by the dry film is etched away. PCB Fabrication Process- Inner Layer Etching Etching All operators need to wear anti-static clothing. The air shower door must clean personnel entering. Therefore, the environmental sanitation requirements are very high. Photo-imaging is the primary process of open and short circuits. The exposed core plate is developed, the unexposed dry film is set to reveal the original copper skin, and the exposed dry film is retained. Inner Layer Imaging Inner FilmĪ dry film is applied to the bare copper core board, and all photo images reactions are performed on the dry film. Generally, it is dried at 150℃ for 3-4 hours.

The primary purpose of drying is to remove the moisture in the board and prevent it from warping during processing. PCB Fabrication Process- Production Prepare Cut LaminationĬutting and laminating according to the size of the finished board or the size of the panel Drying

Then start to arrange production after confirmation. The customer sends us a document it is submitted to the engineer for review and accurate quotation again help confirm whether the production documents are missing or wrong also determine the process steps and associated checks. To ensure the design fulfills minimum tolerances during the manufacturing process, almost all PCB Fab Houses run Design for Manufacture (DFM) checks before circuit boards fabrication.Īfter all the checks are complete, the PCB design can be printed.

So it needs a thorough examination, designers forward PCB files to PC Board Houses for manufacturing.

) to design the circuit, it helps avoid issues caused by discrepancies.ĭifferent PCB design software possibly calls for additional Gerber file generation steps(we provide knowledge about generating Gerber files in Altium and Eagle) they all encode comprehensive vital information, including copper tracking layers, drill drawing, apertures, component notations, and other options. NOTE: Before PCB fabrication, designers should inform their contract manufacturer about the PCB design software version used(Commonly-used PCB design software includes Altium Designer, OrCAD, Pads, KiCad, Eagle, etc. Prototype circuit boards should be rigorously compatible with the designer who creates a PCB layout using PCB design software. You have to take care of certain things while designing the PCB layout, such as the width of the routes, connecting different elements, and placing vias of a specific size. PCB manufacture and design always start with a plan: the designer lays out a blueprint for the PCB that fulfills all the requirements as outlined. To design the PCB layout in any readily available simulator. The beginning step of any PCB manufacture is, of course, the design. PCB Fabrication Process- PCB Design and Layout

We ensure that our products meet our promises through stringent product specifications and quality controls than other suppliers. This ultimate guide covers the most critical steps in the production of PCBs. Here, we will introduce you to the entire PCB fabrication process of our factory. Producing a PCB is a complex process that involves many steps. PCB Fabrication Process employs many new areas of technology that have led to significant improvements in reducing the size of the components and rails used and the reliability of the board. The PCB fabrication process is an essential element of the electronics production lifecycle.
