For designers who are new to circuit boards, a thorough understanding of the production process is essential for effective design. Thus, it is important to gain some insight into circuit board manufacturing.
The basic production process of a circuit board is as follows:
1. **Step 1**: Create a circuit board schematic diagram that meets the requirements based on the circuit’s needs and desired functions. The primary guideline for schematic design is ensuring that the performance and functions of various components are properly aligned. The schematic effectively conveys the circuit board’s intended functionality. Designing the circuit board schematic is the first and most critical step in circuit board production, warranting our full attention.
2. **Step 2**: Once the PCB schematic design is complete, the next task is to effectively package the components using PROTEL software. This ensures that the circuit board components are arranged in a uniform manner, maintaining consistent appearance and size.
**Step 3:** Generate the drawing of the circuit board. Once it is created on the computer, we must position each component according to the dimensions of the specific PCB panel. This ensures that the leads of the components distributed across the circuit board do not cross over each other. Finally, a DRC inspection must be performed on the circuit board to avoid any crossover errors in the pins or leads during the wiring process.
**Step 4:** Use special carbon paper to print the designed PCB diagram with an inkjet printer. Then, press the side with the printed circuit diagram against the copper plate and place it on a heat exchanger for hot printing. This process transfers the circuit diagram ink from the carbon paper to the copper plate.
**Step 5:** Manufacture the circuit board. Prepare a solution by mixing sulfuric acid and hydrogen peroxide in a 3:1 ratio. Immerse the copper plate with ink stains into this solution and wait for about three to four minutes, or until all the copper, except for the ink stains, has been etched away. Remove the copper plate and rinse off the solution with clean water.
**Step 6:** Punch the circuit board. First, use a hole drilling machine to drill the holes marked on the copper-clad board one by one. After this operation is complete, insert each component from the back of the copper-clad board, ensuring that two or more pins are aligned. Then, soldering tools are required to secure the components to the copper-clad board.
**Step 7:** After the soldering process is finished, the next step is to conduct a comprehensive test on the circuit board. If any issues are detected during testing, it is necessary to analyze the PCB schematic diagram to locate the problem. Once identified, re-soldering and replacing components can be carried out. When testing reveals no issues, the production of the circuit board is complete!
