The design of the printed circuit board is based on the circuit schematic diagram to achieve the functions required by the circuit designer. The design of the printed circuit board mainly refers to the layout design, and the layout of the external connection needs to be considered. Optimized layout of internal electronic components. Optimized layout of metal wiring and vias. Electromagnetic protection. Various factors such as heat dissipation. Excellent layout design can save production costs and achieve good circuit performance and heat dissipation. Simple layout designs can be implemented manually, and complex layout designs need to be implemented with computer-aided design (CAD). The following is a description of the world's famous and powerful PCB layout software.
1, protel, Altium Designer-PCB layout software
Protel is indeed one of the lowest-end PCB layout software in the eda software family. It is easy to make a single-panel, double-layer PCB, but the 4-layer PCB is starting to feel bad.
Nowadays, PROTEL has developed into the Altium Designer series. It is a huge EDA software. It is a complete board-level all-round electronic design system. It includes circuit schematic drawing, mixed circuit simulation of analog circuit and digital circuit, and multilayer printed circuit. Board design (including automated routing of printed circuit boards), programmable logic device design, chart generation, spreadsheet generation, support for macro operations, etc., with Client/Server architecture and compatibility with other designs Software file formats, such as ORCAD, PSPICE, EXCEL, etc., the automatic routing of multi-layer printed circuit boards can achieve 100% throughput of high-density PCB。
2, Mentor pads-PCB layout software
Pad is a software developed by MentorGraphics, which is easy to use in low-end products and is suitable for most small and medium-sized businesses. PADSLayout (PowerPCB) provides interfaces to other PCB layout software, CAM processing software, and mechanical design software to facilitate data conversion and transfer in different design environments. The disadvantage is that it is easy to report errors.
3, Allegro-PCB layout software
Allegro is the advanced PCB layout software from Cadence. Allegro provides a good and interactive working interface and powerful functions. Combined with its front-end products Cadence, OrCAD, and Capture, Allegro provides the perfect solution for today's high-speed, high-density, multi-layer complex PCB design and routing.
Allegro stands out in its class. It is mainly designed for high-speed and high-density multi-layer pcb, but it also has obvious shortcomings. It is difficult to get started, and it is expensive. It is not cost-effective for most SMEs.
The difference between PCB and PCBA
What is a PCB? How did PCBA evolve? What is the difference between PCB and PCBA? Let's take a closer look below.
PCB is the abbreviation of Printed Circuit Board. Because it is made by electronic printing, it is called "printing" circuit board. PCB is an impor...
