Geedi socodka PCB naqshadeynta, haddii khataraha suurtagalka ah la sii saadaalin karo horayna looga fogaan karo, heerka guusha ee naqshadeynta PCB si weyn ayaa loo hagaajin doonaa. Shirkado badan ayaa qiimeeya mashaariicda iyagoo tilmaamaya heerka guusha ee guddiga naqshadeynta PCB.

Furaha lagu hagaajinayo heerka guusha ee guddigu waa naqshadaynta sharafta signalada. Naqshadaynta nidaamka elektiroonigga ah ee hadda jira, waxaa jira qorshayaal wax -soo -saar oo badan, soo -saareyaasha chip -ka ayaa sameeyay, oo ay ku jiraan waxa chip loo isticmaalo, sida loo dhiso wareegga durugsan iyo wixii la mid ah. Waqtiga intiisa badan, injineerada qalabka si dhib leh uma baahna inay tixgeliyaan dhibaatada mabda’a wareegga, kaliya waxay u baahan yihiin inay samaystaan ​​PCB iyaga u gaar ah.

Si kastaba ha ahaatee, waxay ku jirtaa habka naqshadeynta PCB -ga in shirkado badan ay la kulmaan dhibaatooyin, ama qaabeynta PCB -ga waa mid aan degganeyn, ama ma shaqeynayo. Shirkadaha waaweyn, soo -saareyaal badan oo jajab ah ayaa siin doona taageero farsamo iyo hagitaan ku saabsan naqshadaynta PCB. Laakiin qaar ka mid ah shirkadaha yaryar iyo kuwa dhexdhexaadka ah ayaa ku adag inay helaan taageeradaas. Sidaa darteed, waa inaad raadsataa hab aad adigu ku samayso, taas oo keenta dhibaatooyin badan, kuwaas oo laga yaabo inay u baahdaan dhowr cadad iyo dib -u -habayn dheer. Dhab ahaantii, haddii aad fahanto habka naqshadeynta nidaamka, tan waa laga fogaan karaa. Here are three tips for reducing PCB design risk.

1, the system planning stage is best to consider the problem of signal integrity, the whole system is built like this, the signal from one PCB to another PCB can receive correctly? Tani waxay u baahan tahay in la qiimeeyo marxaladda hore, mana aha wax adag in la qiimeeyo dhibaatada. Aqoon yar oo ku saabsan daacadnimada signalada iyo dhowr hawlgallo software oo fudud ayaa samayn kara.

Second, in the PCB design process, the use of simulation software to evaluate the specific wiring, observe whether the signal quality can meet the requirements, the simulation process itself is very simple, the key is to understand the principle of signal integrity knowledge, and used for guidance.

Third, in the process of PCB, we must carry out risk control. Waxaa jira dhibaatooyin badan, software jilitaanku ma laha hab lagu xaliyo, waa inuu xakameeyaa naqshadeeye. Furaha tallaabadan ayaa ah in la fahmo halka ay khatartu ku jirto iyo waxa la sameeyo si looga fogaado, mar labaadna la ogaado daacadnimada signalada.

Haddii saddexda dhibcood si fiican loogu fahmi karo geedi socodka naqshadeynta PCB, markaa halista naqshadeynta PCB si weyn ayaa loo dhimi doonaa, suurtagalnimada qaladku aad bay u yaraan doontaa ka dib marka guddiga dib loo soo celiyo, iyo ka saariddu waxay noqon doontaa mid sahlan.
