PCB design is the core Items of the product

Over the years, PCBs seem to be “downgraded” in the field of electronic engineering, becoming an electronic engineer who only pays behind the scenes. Managers believe that PCB layout is a negligible problem, not a design engineer needs to care, but with digital circuits Faster and faster, RF circuits are also placed on the PCB, which has become a limiting factor in many designs. Computer-aided design (CAD) tools can help engineers design boards, but CAD's automatic winding function is usually Will bring more questions...


 Like all new technologies, engineers took a while to accept and promote printed circuit boards (PCBs). In the 1960s, American veteran electronics industry Zeneth always advertised their use of point-to-point wiring. And now, almost all electronic products are built on PCB.



PCB board design software:
1) Domestic use is more protel, protel 99se, protel DXP, Altium, these are a company development, constantly upgrading software, the current version is Altium Designer 15 is relatively simple, the design is more casual, but do complex PCB these The software is not very good.

2) Cadence spb software Cadence spb This is the Cadence software. The current version is Cadence SPB 16.5. The ORCAD schematic design is an international standard. PCB design and simulation are very complete. It is more complicated than protel, mainly required and complicated. However, the design is well regulated, so the design is more effective and more powerful than protel.

3) Mentor's BORDSTATIONG and EE, which BOARDSTATION is only suitable for UNIX systems, not for PC design, so there are fewer people. The current MentorEE version of Mentor EE 7.9 and Cadence spb belong to the same level of PCB design software. Some places are worse than cadence spb, its strength is the pull line, flying line, known as the flying line king.

4) EAGLE Layout This is the most widely used PCB design software in Europe. The above mentioned PCB design software, more used, Cadence spb and MentorEE are well-deserved kings. If it is a beginner design PCB I think Cadencespb is better, it Can give designers a good design habit, and can guarantee good design quality.
