With the rapid development of electronic technology , electronic products have become increasingly demanding , more and more features , although the increasing integration of microarrays , but still can not fully meet the demand , and therefore requires that we be able to progress PCB design to achieve a more rational, more optimized design .
PCB design, PCB design , also known as circuit board called the Printed circuit board, abbreviated as PCB, so the circuit board design , also known as PCB design in English ; circuit board design, draw by hand from the beginning to the present, the more massive component library , and powerful features such as automatic placement and routing , more engineers to help us design the circuit board .
A qualified electronics engineer, engaged in PCB design work must be familiar with more than one circuit board design software. Current mainstream PCB design software and Protel 99se CAM350 two series .
PCB design work carried out , it is a very lengthy process , because , when we conduct circuit board design , it is necessary to choose a suitable own circuit board design , will introduce the following circuit board design tool in everyone select the PCB design software, see which one suitable for them, of course , in their daily use among different tasks, choose a different type of circuit board design software , it is necessary , regardless of what kind of circuit boards design software is not perfect , the key is that we find a cooperative own tools quickly , easily complete their circuit board design.
Circuit board design , concrete can be divided into several parts , namely, schematic design , PCB design, circuit simulation , CAM engineering software , copy board software. Among this paper , we are mainly talking about the circuit board design software , refer to the schematic design and PCB design two parts .
Circuit board design software , generally contain schematic design and PCB design two modules , the mainstream powerful PCB design software, including even more modules , and now the mainstream circuit board design software are PROTEL, OrCAD, Viewlogic, PowerPCB, Cadence PSD, MentorGraphices the Expedition PCB, Zuken CadStart, Winboard / Windraft / Ivex-SPICE, PCB Studio, TANGO, PCBWizard ( with LiveWire supporting PCB production package ), ultiBOARD7 ( with multiSIM2001 supporting PCB production package ) , etc. and so on.
protel software, the most widely used in China , but the current user application pads are constantly increasing, the bottom two were introduced Altium Protel PCB design software series Protel is PROTEL ( currently the Altium) in the late 1980s introduced the circuit board design software , from the initial Protel fo DXS, and then upgrade to Protel for Windows, and then in 1998 , launched protel98, launched a landmark protel 99 and upgraded version of protel 99se in 1999 , currently carried out using Protel 99se PCB design staff , the number is still quite a huge contribution to protel 99se PCB design industry is huge .
