The Evolution of PCB Factory Over the Years

The PCB (printed circuit board) photosensitive process is a key step that uses light to transfer circuit images onto the printed circuit board. Professional PCB factory, with advanced equipment and rich experience to perform this task. The photosensitive process begins by creating an image of the circuit on a computer and converting that image into a format that can be read by a lithography machine. Once the image is created and transformed, it can be transferred to a printed circuit board containing light-sensitive material. When exposed to strong ultraviolet light, light-sensitive materials begin to harden. The parts that are not exposed to ultraviolet light are washed away, leaving behind an image of the hardened circuit. SprintPCB's photosensitive process is not only accurate but also efficient, enabling the rapid production of high-quality printed circuit boards, using the latest equipment and technology to ensure that each board meets customer needs and standards.

PCB(printed circuit board) circuit layout is a complex design that determines the function of a product, and the process of creating these layouts is a fusion of art and science. Using advanced CAD(Computer Aided Design) software, the various electronic components on the circuit board, such as resistors, capacitors and integrated circuits, are carefully set up. This is the process of connecting these components using conductive rails while minimizing interference. After identification, undergo a review process. Check for potential problems, such as signal interference or heat issues. This involves several steps, including etching, drilling and welding, all of which are carried out on precision machinery at the SprintPCB factory.

Computer Aided Design (CAD) software is used to design accurate modeling and simulation, using CAD software that allows designers to create and test circuit board designs in a virtual environment.  Help designers draw circuit diagrams, place components, and perform electrical performance tests.  It also has a powerful simulation function, which designers can use to simulate the performance of the board under various conditions, including temperature changes, voltage fluctuations, and so on.  This ensures that the circuit board can provide stable and reliable performance in actual use.  CAD software can communicate directly with production equipment, converting design data into instructions that the machine can understand.

Lithography is an important process for the production of printed circuit boards (PCBS) at the SprintPCB factory, and the first step is to prepare the artwork. Will print to film or photomask. The photomask is a transparent sheet etched with a circuit pattern, and this specialized device is aligned on a copper-clad plate. Once the photomask and the copper plate are aligned, the photomask shields specific areas of the copper surface while leaving other areas exposed. This exposure alters the solubility of the photosensitive material applied to the surface of the plate, allowing it to be selectively removed from the exposed area. A developing board that removes light-sensitive materials from areas exposed to light. The remaining material forms a circuit pattern on the copper surface. The uncovered copper is then etched away with a chemical solution to remove any excess copper from the board surface. By employing advanced technology and high-quality materials, SprintPCB factories ensure that their PCBS are reliable and durable, meeting the needs of customers in various industries.
