Kwinkqubo ye PCB uyilo, ukuba kunokwenzeka ingozi kunokuxelwa kwangaphambili kwaye kuthintelwe kwangaphambili, izinga lokuphumelela loyilo lwe-PCB liya kuphuculwa kakhulu. Iinkampani ezininzi zivavanya iiprojekthi ngesalathiso sezinga lokuphumelela kwebhodi yoyilo ye-PCB.

Isitshixo sokuphucula umgangatho wempumelelo webhodi kuyilo lwendlela yokuthembeka. Kuyilo lwenkqubo ye-elektroniki yangoku, zininzi izicwangciso zemveliso, abenzi be-chip bazenzile, kubandakanya ne-chip oza kuyisebenzisa, indlela yokwakha isekethe yomda kunye njalo njalo. Uninzi lwexesha, iinjineli zehardware akufuneki ziqwalasele ingxaki yomgaqo wesekethe, kufuneka zenze i-PCB yazo.

Nangona kunjalo, kukwinkqubo yokuyila i-PCB ukuba amashishini amaninzi ahlangabezana nobunzima, nokuba uyilo lwePCB aluzinzanga, okanye alusebenzi. Kumashishini amakhulu, abavelisi abaninzi be-chip baya kubonelela ngenkxaso yezobugcisa kunye nesikhokelo kuyilo lwe-PCB. Kodwa amanye amashishini amancinci naphakathi anengxaki yokufumana inkxaso enjalo. Ke ngoko, kuya kufuneka ufumane indlela yokwenza ngokwakho, ekhokelela kwiingxaki ezininzi, ezinokufuna iihlelo ezininzi kunye nexesha elide lokulungisa ingxaki. Ngapha koko, ukuba uyayiqonda indlela yoyilo yenkqubo, oku kunokuthintelwa. 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? Oku kufuna ukuvavanywa kwinqanaba lokuqala, kwaye akukho nzima ukuvavanya ingxaki. Ulwazi oluncinci lokuthembeka komqondiso kunye nemisebenzi embalwa elula yesoftware inokuyenza.

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. Zininzi iingxaki, isoftware yokulinganisa ayinandlela yokusombulula, kufuneka ilawulwe ngumyili. Isitshixo seli nyathelo kukuqonda ukuba buphi ubungozi kwaye wenzeni ukubathintela, kwakhona ngolwazi lokunyaniseka komqondiso.

Ukuba la manqaku mathathu anokubanjwa kakuhle kwinkqubo yoyilo lwe-PCB, umngcipheko woyilo lwe-PCB uya kuncitshiswa kakhulu, ukubakho kwempazamo kuya kuba kuncinci kakhulu emva kokuba ibhodi ibuyiselwe umva, kwaye ukulungisa ingxaki kuya kuba lula.
