Iibhodi zesekethe ze-PCB zisetyenziswa ngokubanzi kwiimveliso ezahlukeneyo ze-elektroniki kwihlabathi lanamhlanje eliphuhlileyo. Ngokutsho kwamashishini ahlukeneyo, umbala, imilo, ubungakanani, umaleko, kunye nezinto zeebhodi zesekethe zePCB zahlukile. Ngoko ke, ulwazi olucacileyo luyafuneka kuyilo lweebhodi zeesekethe ze-PCB, ngaphandle koko ukungaqondi kakuhle kuyenzeka. Eli nqaku lishwankathela iziphene ezilishumi eziphezulu ngokusekelwe kwiingxaki kwinkqubo yoyilo lweebhodi zesekethe zePCB.
1. Inkcazo yenqanaba lokucubungula ayicacanga
Ibhodi enecala elinye yenzelwe kwi-TOP layer. Ukuba akukho myalelo wokwenza ngaphambili nangasemva, kunokuba nzima ukuthengisa ibhodi ngezixhobo kuyo.
2. Umgama phakathi kwendawo enkulu yefoyile yobhedu kunye nesakhelo sangaphandle sisondele kakhulu
Umgama phakathi kwefoyile yobhedu yendawo enkulu kunye nesakhelo sangaphandle kufuneka sibe yi-0.2mm ubuncinane, kuba xa ugaya imilo, ukuba igalelwe kwi-foil yobhedu, kulula ukubangela ukuba i-foil yobhedu idibanise kwaye ibangele ukuba i-solder ixhathise. ukuwa.
3. Sebenzisa iibhloko zokugcwalisa ukuzoba iipads
Ukuzoba iipads ezineebhloko zokugcwalisa kunokudlula uhlolo lwe-DRC xa kuyilwa iisekethe, kodwa hayi ukusetyenzwa. Ke ngoko, iipads ezinjalo azikwazi ukuvelisa ngokuthe ngqo idatha yemaski ye-solder. Xa ukuchaswa kwe-solder kusetyenziswe, indawo yebhloko yokuzalisa iya kugutyungelwa ngokumelana ne-solder, okubangela ukuba isixhobo I-Welding inzima.
4. Umaleko womhlaba wombane uyintyatyambo yeentyatyambo kunye noqhagamshelo
Ngenxa yokuba yenzelwe ukunikezelwa kwamandla ngendlela yeepads, umgangatho womhlaba uchasene nomfanekiso kwibhodi eprintiweyo yangempela, kwaye zonke iidibaniso ziyimigca eyodwa. Qaphela xa udweba iiseti ezininzi zonikezelo lwamandla okanye imigca emininzi yokuhlukanisa umhlaba, kwaye ungashiyi izikhewu ukwenza amaqela amabini Isiphaluka esifutshane sonikezelo lwamandla asinakubangela ukuba indawo yokudibanisa ivalwe.
5. Abalinganiswa abangafanelekanga
Iipads ze-SMD ze-cover cover pads zizisa ukuphazamiseka kwi-on-off test yebhodi eprintiweyo kunye ne-welding component. Ukuba uyilo loonobumba luncinci kakhulu, luyakwenza ushicilelo lwesikrini lube nzima, kwaye ukuba lukhulu kakhulu, abalinganiswa baya kuthibelana, benze kube nzima ukwahlula.
Iiphedi zesixhobo sokuxhoma 6.zimfutshane kakhulu
Olu lolovavanyo lwe-on-off. Kwizixhobo ezixineneyo kakhulu zokukhwela umphezulu, umgama phakathi kwezikhonkwane ezimbini mncinci kakhulu, kwaye iipads zikwabhityile kakhulu. Xa ufaka izikhonkwane zokuvavanya, kufuneka zigxadazwe phezulu naphantsi. Ukuba i-pad design imfutshane kakhulu, nangona ingekho Iya kuchaphazela ukufakwa kwesixhobo, kodwa iya kwenza ukuba izikhonkwane zokuvavanya zihluke.
7. Isetingi yephedi yecala elinye kwindawo yokuvula
Iiphedi ezinecala elinye aziqhelwanga. Ukuba imingxuma egrunjiweyo idinga ukumakishwa, indawo yokuvula kufuneka yenziwe njenge-zero. Ukuba ixabiso liyilelwe, ngoko xa idatha yokugaya yenziwe, ulungelelwaniso lomngxuma luya kubonakala kule ndawo, kwaye iingxaki ziya kuvela. Iiphedi ezicalanye ezifana nemingxuma egrunjiweyo kufuneka ziphawulwe ngokukodwa.
8. Ukudityaniswa kweepadi
Ngexesha lenkqubo yokugaya, i-drill bit iya kuphulwa ngenxa yokugaya ezininzi kwindawo enye, okubangela umonakalo womngxuma. Imingxunya emibini kwibhodi ye-multi-layer idibanisa, kwaye emva kokuba i-negative izotywa, iya kubonakala njengeplate yokuhlukanisa, okubangela i-scrap.
9. Kukho iibhloko ezininzi zokuzalisa kuyilo okanye iibhloko zokuzalisa zizaliswe ngemigca emincinci kakhulu
Idatha yokufota ilahlekile, kwaye idatha yokufota ayiphelelanga. Ngenxa yokuba ibhloko yokuzalisa itsalwa nganye nganye ekusekweni kwedatha yokukhanya, ngoko ke inani ledatha yomzobo okhanyayo owenziweyo mkhulu kakhulu, okwandisa ubunzima bokucubungula idatha.
10. Ukusetyenziswa kakubi komgangatho wegraphic
Olunye unxibelelwano olungenamsebenzi lwenziwe kwezinye iileya zegraphics. Ekuqaleni yayiyibhodi enemigangatho emine kodwa iileya ezingaphezu kwesihlanu zeesekethe ziyilwe, nto leyo ebangele ukungaqondi kakuhle. Ukwaphulwa koyilo oluqhelekileyo. Umaleko wegrafiki kufuneka ugcinwe ucocekile kwaye ucace xa uyilwa.
