Enqubeni ye- PCB design, uma kungenzeka izingozi zingabikezelwa kusengaphambili futhi zigwenywe kusengaphambili, izinga lokuphumelela kwe-PCB design lizothuthukiswa kakhulu. Izinkampani eziningi zihlola amaphrojekthi ngenkomba yezinga lempumelelo lebhodi yokwakha ye-PCB.

Isihluthulelo sokwenza ngcono izinga lokuphumelela kwebhodi ukuklama ubuqotho besiginali. Ekuklanyeni kwamanje kohlelo lwe-elekthronikhi, kunezinhlelo eziningi zomkhiqizo, abenzi be-chip abakwenzile, kufaka phakathi ukuthi iyiphi i-chip ezosetshenziswa, indlela yokwakha isekhethi lomngcele njalonjalo. Isikhathi esiningi, onjiniyela behadiwe akudingeki bacabangele inkinga yesimiso sesifunda, badinga nje ukwenza i-PCB yabo.

Kodwa-ke, kunqubo ye-PCB design lapho amabhizinisi amaningi ahlangabezana nobunzima, noma ukwakheka kwe-PCB kungazinzile, noma kungasebenzi. Kumabhizinisi amakhulu, abakhiqizi abaningi be-chip bazohlinzeka ngosizo lobuchwepheshe kanye nokuholwa ekwakhiweni kwe-PCB. Kepha amanye amabhizinisi amancane naphakathi nendawo anenkinga yokuthola ukusekelwa okunjalo. Ngakho-ke, kufanele uthole indlela yokukwenza ngokwakho, okuholela ezinkingeni eziningi, ezingadinga izinhlelo eziningana nesikhathi eside sokulungisa amaphutha. Eqinisweni, uma uqonda indlela yokwakha yohlelo, lokhu kungagwemeka. 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? Lokhu kudinga ukuhlolwa kusenesikhathi, futhi akunzima ukuhlola inkinga. Ulwazi oluncane ngobuqotho besiginali kanye nokusebenza okulula kwesoftware kungakwenza.

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. Kunezinkinga eziningi, isoftware yokulingisa ayinandlela yokuyixazulula, kufanele ilawulwe ngumklami. Ukhiye walesi sinyathelo ukuqonda ukuthi zingakuphi izingozi nokuthi yini okufanele uyenze ukuzigwema, futhi ngolwazi lobuqotho besiginali.

Uma amaphuzu amathathu angabanjwa kahle kwinqubo yokwakhiwa kwe-PCB, khona-ke ingozi yokwakha i-PCB izoncishiswa kakhulu, amathuba wephutha azoba mancane kakhulu ngemuva kokudonswa emuva kwebhodi, futhi ukulungisa iphutha kuzoba lula.
