Embodiment 1

[0037] Such as figure 1 As shown, the PCB packaging architecture method of the present embodiment includes the following steps:

[0038] 1. If image 3 As shown, a logic symbol is established in the logic symbol library, which includes the pins and mounting holes of the component and its auxiliary components. Among them, the auxiliary components of the components include: heat dissipation components, positioning components and structural firmware. The aforementioned logic notation (see image 3 ) is in the case of figure 2 The traditional logic symbol of the component is made by adding the logic of the pins and mounting holes of the auxiliary component, image 3 Middle A is the logic of mounting holes and positioning holes required for structure and heat dissipation.

[0039] 2. Establish traditional packaging symbols for components (such as Figure 4 shown), and then establish an auxiliary packaging symbol according to the structural characteristics of the auxiliary co...

Abstract

The invention discloses a PCB (printed circuit board) packaging architecture method, which includes the steps: setting up a logic symbol in a logic symbol library, wherein the logic symbol comprises pins and mounting holes of an element and an auxiliary component thereof; setting up a traditional packaging symbol of the element, setting up an auxiliary packaging symbol according to the structural characteristics of the auxiliary component of the element, and combining the traditional packaging symbol and the auxiliary packaging symbol into integrated package or associating the traditional packaging symbol with the auxiliary packaging symbol into a combined packaging symbol; and mapping the logic symbol and the corresponding integrated package or combined package, and storing the integrated package or combined package into a PCB packaging bank for integral calling or combination calling. Using the PCB packaging architecture method can improve operating efficiency, reduce repetitive operations in PCB design and improve PCB design accuracy.

Description

technical field [0001] The invention relates to PCB (printed board) design, in particular to a method for PCB package structure. Background technique [0002] Integrated circuit packaging not only plays the role of connecting the bonding points in the integrated circuit chip with the external circuit, but also provides a stable and reliable working environment for the integrated circuit chip, and protects the integrated circuit chip mechanically or environmentally, so that the integrated circuit The chip can perform normal functions, and its high stability and reliability are guaranteed. With the continuous development of wafer technology, the size of transistors continues to decrease. According to Moore's Law, the number of transistors that can be accommodated on an integrated circuit will double every 18 months, and the performance will also double; Therefore, the complexity of integrated circuit packaging is also constantly increasing, and the packaging form has also dev...
