Over the years, PCB seems to have been "downgraded" in the field of electronic engineering, and has become an unknown hero who silently paid behind the scenes. The managers believe that the PCB wiring is insignificant manufacturing problem, not what design engineers need to care; It is getting faster and faster, and the RF circuit is also put into the PCB. The circuit board has become a limited factor in many designs. Although the computer -aided design (CAD) tool can help engineers design circuit boards, the automatic winding function of CAD usually will usually be Bring more problems ...

     Just like all new technologies, the engineer took a while to accept and promote the printing circuit board (PCB). In the 1960s, the old American electronics operator Zeneth President President Point-To-Point WIRING, as shown in Figure 1; now, almost all electronic products are made of PCB.

     However, for many years, PCB seems to have been "downgraded" in the field of electronics engineering, and has become an unknown hero who silently paid behind the scenes. The managers believe that the PCB wiring is an insignificant manufacturing problem, not what design engineers need to care; It is getting faster and faster, and the RF circuit is also put into the PCB. The circuit board has become a limited factor in many designs. Although the computer -aided design (CAD) tool can help engineers design circuit boards, the automatic winding function of CAD is usually usually the function. It will bring more problems.

  My master, John Massa boss taught me the centrality of my PCB in the design work (Centrality); Massa's boss always finds a new method of designing and creating circuit boards. When our peers are still discussing the instructions of the 68020 chip, Massa is already talking about the circuit board wrap and the prototype production that can be completed in one night.

     Massa said: "In my 40 years of electronic design experience, the circuit board always hinders the restricted factors of each design project;" you should not just make the circuit diagram in order to cope with the work. The circuit diagram is converted into a certain product that can be created and sold.

     Modern PCB is not only a time killer, but also a key component with precise design requirements; the operating frequency and signal rising/down time of electronic devices have become faster and faster, so PCB has become increasingly important. Look at the following small stories that have happened, you will get some inspiration.
