1. Injongo yoyilo lwe-PCB kufuneka icace. Imigca ebalulekileyo ebalulekileyo, ubude be-wiring kunye nokuqhubekisa ii-lops zomhlaba kufuneka zibe ngqongqo kakhulu. Kwisantya esisezantsi kunye nokungafani kwemigca yomqondiso, inokubekwa kwindawo ephambili ye-wiring kancinci. . Iinxalenye ezibalulekileyo zibandakanya: ukwahlulwa kombane; Iimfuno zabade zemigca yewotshi yememori, imigca yokulawula kunye nemigca yedatha; I-wiring yemigca yokukhawulezisa eyakhawulezayo, njl. Njl. I-wiring yeli candelo ibaluleke kakhulu. I-TOPOLOTION yokusasazwa kwemigca yolawulo kunye nemigca yedilesi, kunye nolawulo lobude lolawulo lwemigca yedatha kunye nemigca yewoyini kufuneka ithathelwe ingqalelo. Kwinkqubo, ngokwephepha ledatha ye-chip kunye ne-frequency yenyani, imigaqo ethile ye-wiring inokufumaneka. Umzekelo, ubude bemigca yedatha kwiqela elinye akufuneki ukuba bahluke ngaphaya kweMils engaphezulu, kunye nomahluko wobude phakathi kwejelo ngalinye akufuneki ludlule iils ezininzi. Mil njalo njalo. Xa zimiselwe ezi mfuno, abayili be-PCB banokucelwa ngokucacileyo ukuba bazisebenzise. Ukuba zonke iimfuno ezibalulekileyo zokulondolozwa kucacile, zinokuguqulwa zibe zizithintelo zemingxunya kuphela, kwaye isoftware yesoftware ezenzekelayo kwi-CAD inokusetyenziswa ukufezekisa uyilo lwe-PCB. Ikwayindlela yophuhliso kwi-PCB ye-PCB ephezulu.

2. Ukuhlolwa kunye nokugqwetha xa ulungiselela iBhodi, qiniseka ukuba kukho i-Multing Pines kwi-PIN, igcinwe ukuba ingaba ikhona i-Multing ye-TIn, i-PIN., Njl njl. Lo mkhwa ulungileyo unokuthintela ukonakaliswa ebhodini emva kokugoba ngamandla. Kwinkqubo yokulungisa ingxaki, kufuneka ube nengqondo yoxolo. Yinto eqhelekileyo kakhulu ukuba idibane neengxaki. Into ekufuneka uyenzile kukuthelekisa ngakumbi kunye nohlalutyo, kwaye ngokuthe ngcembe ukuphelisa oonobangela. Kuya kufuneka ukholelwe ngokuqinileyo ukuba "yonke into inokusonjululwa" kunye "neengxaki kufuneka zisonjululwe." Kukho isizathu sayo ", ukuze ukuba ubudygungcy bube yimpumelelo ekugqibeleni.

3. Amanye amagama anesishwankathelo ngoku ukusuka kwimbono yobugcisa, yonke uyilo linokuhlala ekugqibeleni, kodwa impumelelo yeprojekthi, iQela eliQhelekileyo, iQela eliSebenzayo, kunye nezinto ezinokwenziwa, kunye namalungiselelo abasebenzi anokuqinisekisa impumelelo yeprojekthi. Injineli ye-hardware ingumphathi weprojekthi. Kuya kufuneka anxibelelane nehlabathi elingaphandle ukufumana iimfuno zoyilo lwawo, emva koko ashwankathe kwaye azihlaziye zibe zizinto ezithile zekhompyuter. Kukwayimfuneko ukunxibelelana ne-chip ezininzi kunye nababoneleli sisisombululo sokukhetha isisombululo esifanelekileyo. Xa kugqityiwe umzobo occkimatic, kuya kufuneka alungiselele abalingane ukuba basebenzisane novavanyo kunye nokuhlolwa, kwaye nokusebenza neenjineli ze-CAD ukugqiba uyilo lwe-PCB. . Kwangelo xesha, lungiselela uluhlu lwe-bom, qala ukuthenga kunye nokulungiselela izixhobo, kwaye uqhagamshelane nomvelisi wokulungisa ukugqibezela ukufakwa kwebhodi. Kwinkqubo yokulungisa ingxaki, kufuneka aququzelele abanjineli besoftware ukusombulula iingxaki eziphambili ngokudibeneyo, besebenzisana neenjineli zovavanyo ukusombulula iingxaki ezifunyenwe kuvavanyo, kwaye balinde ukuba imveliso isungulwe kwindawo. Ukuba kukho ingxaki, kufuneka ixhaswe ngexesha. Ke ngoko, ukuba ngumyili wehardware, kufuneka usebenzise izakhono zonxibelelwano ezilungileyo, amandla okuhlengahlengiswa kunye nokwenza izigqibo xa ujongene nemicimbi emininzi ngaxeshanye, nesimo sengqondo esihle nesinoxolo. Kukho ukhathalelo kunye nobunzulu, kuba ukungakhathali okuncinci kwi-Hardware uyilo luhlala lubangela ilahleko enkulu yoqoqosho. Umzekelo, xa iBhodi yenzelwe kwaye amaxwebhu okugqiba kugqityiwe ngaphambili, ukungasebenzi kubaluleke kakhulu ungqimba kunye nomaleko womhlaba ukuze uqhagamshelwe. Kwangelo xesha, emva kokuba ibhodi ye-PCB yenziwe, yabekwa ngokuthe ngqo kumgca wokuvelisa ngaphandle kokuhlolwa. Kwakufunyanwa kuphela ngexesha lovavanyo kuphela apho kwafunyanwa ingxaki yesekethe emfutshane, kodwa amacandelo esele ethengisiwe ebhodini, okukhokelela kumakhulu amawaka elahleko. Ke ngoko, ukuhlolwa ngononophelo nangovavanyo olunamandla, uvavanyo olunoxanduva, kunye nokuqokelelwa kwenqanaba le-Hardware kunokwenza inkqubela phambili eqhubekayo, emva koko wenze impumelelo kwishishini.
