The design drawing of the PCB schematic diagram should be neat, with clear characters, thick lines and clear subdivisions, making it easy to read. It is essential that the schematic diagram follows national standards.
The layout should be uniform. Planning the location of various graphic symbols in advance and determining the size of the graphic symbols are important steps. The main PCB manufacturer’s principle drawing should be positioned above the PCB layout drawing, or on another page, to ensure that the entire drawing is evenly and coordinated. Failing to do so may lead to difficulties in understanding the layout and potential errors.
The PCB manufacturer must label the position symbol of each component to the left or above its corresponding symbol on the drawing. Each position symbol consists of text symbols (letters) and footnote serial numbers (numbers). Components should be marked with position sequence numbers, such as R1, R2, R3… for resistors, and C1, C2, C3… for capacitors, based on their positions in the figure from top to bottom and left to right. If a product comprises multiple units, its sequence number can be compiled accordingly, like 3R1, 3C1, etc.
To facilitate reading the diagram, the code and basic data of each component provided by the PCB manufacturer can be directly written on the diagram, or a component list can be attached. The component list should detail the number, code, name, model, and quantity of each component, among other information. Components should be classified, and the sequence numbers of similar components should be filled in from top to bottom. After listing one type of component, leave a row before listing another type. During component assembly, it is crucial to install and solder them strictly according to the components listed in the detailed list. Series components are best drawn on a straight line, with their symbol centers aligned when connected in parallel.
