Kuphando lwe PCB iteknoloji yokujika umva, umva wokutyhala umzobo wesakhelo ubhekisa umva wefayile yefayile yePCB okanye umzobo wesekethe wePCB uzotywe ngokuthe ngqo ngokwento ebonakalayo yemveliso, ukuze uchaze umgaqo kunye nemeko yokusebenza kwebhodi yesekethe. Ukongeza, umzobo wesekethe ukwasetyenziselwa ukuhlalutya ukusebenza kweemveliso ngokwazo. Kuyilo lwangaphambili, uphuhliso lwemveliso ngokubanzi kufuneka luqale lwenze uyilo lwesikim, emva koko lwenze uyilo lwePCB kuyilo loyilo.

I-schematic ye-PCB inendima ekhethekileyo, nokuba isetyenziselwa ukuhlalutya imigaqo yebhodi yesekethe kunye neempawu zokusebenza kwemveliso kufundo olubuyela umva, okanye njengesiseko kunye nesiseko kuyilo lwe-PCB kuyilo lwangaphambili. Ke, ungawutshintsha njani umba we-PCB, kwaye zeziphi iinkcukacha ekufuneka ziqwalasele inkqubo yokubuyela umva, isekwe kumaxwebhu okanye kwizinto eziyinyani?

1. Yahlula ngokufanelekileyo iindawo ezisebenzayo

Xa umzobo wesikimu sebhodi ye-PCB uyilelwe ngokwahlukileyo, ukwahlulwa ngokufanelekileyo kweendawo ezisebenzayo kunokunceda iinjineli zinciphise ingxaki engeyomfuneko kwaye ziphucule ukusebenza komzobo.Ngokubanzi, izinto ezinomsebenzi ofanayo kwi-PCB ziya kulungiswa ngendlela esembindini, kwaye indawo esebenzayo yokuhlukanisa inokuba nesiseko esilungileyo nesichanekileyo xa iskimatic ibuyiselwe umva. Nangona kunjalo, ukwahlulwa kwale ndawo yokusebenza akungqinelani. Ifuna iinjineli ukuba zibe nokuqonda okuthile kolwazi olunxulumene nesekethe lwe-elektroniki. Kuqala, fumana izinto ezingundoqo kwiyunithi esebenzayo, emva koko ngokonxibelelwano lomkhondo, fumana ezinye izinto zento efanayo, kwaye wenze ulwahlulo olusebenzayo. Ukusekwa kwezahlulelo ezisebenzayo sisiseko sesikimu. Kwakhona, ungalibali ukusebenzisa iinombolo zecandelo ebhodini ngexesha lenkqubo, ezinokukunceda ukwahlula ukusebenza ngokukhawuleza.

2. Fumana iibhentshi

Esi salathiso sinokuthi siyinxalenye ephambili yebhodi yekopi ye-PCB ekuqaleni komzobo wobugcisa. Emva kokuba iinxalenye zesalathiso zichongiwe, ukuzoba ngokungqinelana nezikhonkwane zala malungu ekubhekiswa kuwo kunokuqinisekisa ukuchaneka komzobo wesikimu kwinqanaba elikhulu. Ukuzimisela kwenxalenye yesalathiso ayisiyongxaki inzima kwiinjineli. Ngokwesiqhelo, icandelo elidlala indima enkulu kwisekethe linokukhethwa njengecandelo lesalathiso. Zihlala zikhulu kwaye zinezikhonkwane ezininzi, ekulula ukuzolula. Njengeesekethe ezihlanganisiweyo, abaguquli, abaguquli, njl., Banokusebenza njengesalathiso esifanelekileyo.

3, ukwahlula ngokuchanekileyo imigca, umgca ofanelekileyo

Ukwahlula umhlaba, amandla kunye nemigca yemiqondiso, iinjineli nazo kufuneka zibe nolwazi lokunikezelwa kwamandla, uqhagamshelo lwesekethe, iintambo zePCB njalo njalo. Umahluko phakathi kwezi zingcingo ungahlalutywa kunxibelelwano lwezinto, ububanzi befoyile yobhedu kwisekethe, kunye neempawu zombane ngokwazo. Kwimizobo ye-wiring, iingcingo zomhlaba zingasetyenziselwa kwinani elikhulu leesimboli zomhlaba ukunqanda ukuwela nokusasaza imigca. Imigca inokubonwa ngokucacileyo ngokusebenzisa imigca eyahlukeneyo ngemibala eyahlukeneyo, kwaye iisimboli ezikhethekileyo zinokusetyenziselwa izinto ezahlukeneyo, kwaye kwaneesekethe zeyunithi zinokutsalwa ngokukodwa kwaye ekugqibeleni zidityaniswe.

4. Yazi kakuhle inkqubo-sikhokelo esisiseko kwaye ujonge kwimizobo efanayo efanayo

Kwezinye iindlela ezisisiseko zesakhelo se-elektroniki kunye neendlela zokuzoba zomgaqo, iinjineli kufuneka zikwazi, kungekuphela nje ukuzoba ngokuthe ngqo ukwenziwa kwesiseko seyunithi elula kunye neklasikhi, kodwa ikwenze nesakhelo esipheleleyo seesekethe zombane. Kwelinye icala, musa ngoyaba iimveliso ezifanayo elektroniki kwibhodi ikopi umzobo wesikimu womzobo uye ukufana ezithile. Iinjineli zinokusisebenzisa ngokupheleleyo iskimu esifanayo ukwenza umva kwisikimu esitsha semveliso esekwe kumava.

5. Jonga kwaye wenze ngcono

Emva kokugqiba iskimu, kufuneka ubuyisele uyilo lwe-PCB ngokuvavanya nokujonga amakhonkco. Ixabiso lamagama ezinto ezibuthathaka kwiiparitha zokuhanjiswa kwePCB kufuneka zihlolwe kwaye zilungiselelwe. Ngokomzobo wefayile ye-PCB, umzobo wesikimu uthelekiswa kwaye uhlahlelwe ukuqinisekisa ukuba umzobo wesikim uyafana ngokufanayo nomzobo wefayile. Ukuba ulungelelwaniso lwesikimu lufunyenwe lungazifezekisi iimfuno ngexesha lokuhlolwa, ulungelelwaniso luya kuhlengahlengiswa kude kube kufanelekile ngokupheleleyo, kumiswe emgangathweni, kuchanekile kwaye kucacile.
