Example Embodiment
[0036] Example 1 :
[0037] Such as figure 1 As shown, the PCB packaging structure method of this embodiment includes the following steps:
[0038] 1. Such as image 3 As shown, a logic symbol is established in the logic symbol library, and the logic symbol includes pins and mounting holes of components and auxiliary components. Among them, the auxiliary components of the component include: heat dissipation components, positioning components and structural firmware. The aforementioned logical symbols (see image 3 ) Is like figure 2 The traditional logic symbols of the components are made by adding auxiliary component pins and mounting holes logic, image 3 Middle A is the logic of mounting holes and positioning holes required for structure and heat dissipation.
[0039] 2. Establish traditional package symbols for components (such as Figure 4 As shown), an auxiliary package symbol is established according to the structural characteristics of the auxiliary component of the component
Example Embodiment
[0043] Example 2:
[0044] Such as Image 6 As shown, the PCB packaging structure method of the present invention includes the following steps:
[0045] 1. Create a traditional logic symbol of a component in the logic symbol library (such as Figure 7 Shown); create a new auxiliary logic symbol (such as Figure 8 As shown), the auxiliary logic symbol includes the logic of the pin and mounting hole of the auxiliary component of the component, and the traditional logic symbol is automatically associated with the auxiliary logic symbol. Among them, the auxiliary components of the component include: heat dissipation components, positioning components, and structural firmware.
[0046] 2. Establish traditional package symbols for components (such as Picture 9 Shown), and then create an auxiliary package symbol according to the structural characteristics of the auxiliary component of the component (such as Picture 10 As shown), the auxiliary package symbol includes the package of the pin
