Kwihlabathi elivela ngokukhawuleza le-elektroniki, imfuno ye-PCB esebenza kakhulu ayizange ibe nkulu. Phakathi kweentlobo ngeentlobo ze-PCB, i-PCB ene-6-layer ivelele ngenxa yokukwazi kwayo ukwamkela i-circuitry enzima ngelixa igcina i-compact form factor. Eli nqaku lijonge kubugocigoci be-6L PCB, ngakumbi leyo inemingxuma engaboniyo, kwaye iphonononga indima yabavelisi be-PCB ekunikezeni iimveliso ezikumgangatho ophezulu ezinemiphetho ephezulu efana ne-EING.
Ukuqonda i-6L PCB
I-PCB ene-6-layer iqulathe imigangatho emithandathu yokuqhuba eyahlulwe ngemathiriyeli yokugquma. Olu lungelelwaniso lwemigangatho emininzi luvumela ukwanda koxinzelelo lwesekethe, luyenza ilungele usetyenziso kunxibelelwano lomnxeba, i-elektroniki yabathengi, kunye neenkqubo zeemoto. Amaleko aqhele ukucwangciswa ngolungelelwaniso oluthile lokwandisa imfezeko yomqondiso kunye nokunciphisa ukuphazamiseka kwe-electromagnetic interference (EMI).
Ulwakhiwo lwe-6L PCB lubandakanya iinkqubo ezininzi ezibalulekileyo, kubandakanywa ukupakishwa komaleko, ukulalisa, ukugrumba, kunye ne-etching. Inyathelo ngalinye kufuneka lenziwe ngokuchanekileyo ukuqinisekisa ukuba imveliso yokugqibela ihlangabezana neemfuno ezingqongqo zezixhobo zombane zanamhlanje.
Ukubaluleka kwemingxuma eyimfama
Enye yezinto ezintsha ezinokuthi zifakwe kwi-6L PCB kukusetyenziswa kwemingxuma eyimfama. Umngxuma oyimfama ngumngxuma ongahambi yonke indlela ngePCB; idibanisa umaleko omnye okanye ngaphezulu kodwa ingabonakali ukusuka kwelinye icala. Esi siqalelo soyilo siluncedo ngakumbi kwiimpawu zendlela kunye noqhagamshelo lwamandla ngaphandle kokubeka esichengeni imfezeko yonke yebhodi.
Imingxunya engaboniyo inokunceda ukunciphisa unyawo lwebhodi, ivumela uyilo oluxineneyo. Bakwaququzelela ulawulo olungcono lwe-thermal ngokubonelela ngeendlela zokutshatyalaliswa kobushushu. Nangona kunjalo, ukwenziwa kwemingxunya engaboniyo kufuna ubuchule obuphambili kunye nokuchaneka, oko kukwenza kubaluleke ukusebenzisana nomenzi wePCB obekekileyo.
Indima yabavelisi bePCB
Ukukhetha umenzi we-PCB ofanelekileyo kubalulekile ekuphumezeni umgangatho ophezulu we-6L PCB ezinemingxuma engaboniyo. Umenzi othembekileyo uya kuba nobuchule obufunekayo, iteknoloji, kunye namanyathelo okulawula umgangatho ukuze aqinisekise ukuba imveliso yokugqibela ihlangabezana nemigangatho yoshishino.
Xa ukhetha umenzi wePCB, qwalasela le miba ilandelayo:
Amava kunye nobuGcisa: Khangela abavelisi abanerekhodi eqinisekisiweyo ekuveliseni ii-PCB zamanqanaba amaninzi, ngakumbi abo banobuchwepheshe bomngxuma oyimfama.
Itekhnoloji neZixhobo:Iinkqubo zokuvelisa ezikwinqanaba eliphezulu, ezifana nokugrumba i-laser kunye nokuhlolwa kwe-automated optical inspection (AOI), zibalulekile ekudaleni imingxunya eyimfama echanekileyo.
Ukuqinisekisa umgangatho:Umenzi ohloniphekileyo uya kusebenzisa imilinganiselo engqongqo yokulawula umgangatho, kubandakanywa ukuvavanywa kokusebenza kombane kunye nokunyaniseka komatshini.
Ukhetho Lwenu:Ukukwazi ukwenza uyilo, kubandakanywa ubungakanani kunye nokubekwa kwemingxuma engaboniyo, kubalulekile ukuhlangabezana neemfuno zeprojekthi.
I-Resin Plug Holes: Isisombululo seMingxunya eyimfama
Ukuphucula ukusebenza kwee-PCB ze-6L ezinemingxuma eyimfama, abavelisi bahlala besebenzisa imingxuma yeplagi ye-resin. Obu buchule bubandakanya ukuzalisa imingxuma eyimfama ngesixhobo sentlaka, esisebenza ngeenjongo ezininzi:
Ukwahlulwa koMbane:Imingxuma yeplagi ye-resin inceda ukukhusela iibhulukhwe zombane phakathi kweengqimba, ukuqinisekisa ukusebenza okuthembekileyo.
Ukuzinza koomatshini: I-resin yongeza ingqibelelo yesakhiwo kwi-PCB, iyenza ixhathise ngakumbi kuxinzelelo lomatshini.
Ukugqitywa komphezulu: EING
Ukugqitywa komphezulu wePCB yinto ebalulekileyo echaphazela ukusebenza kwayo kunye nokuthembeka. I-EING lukhetho oludumileyo phakathi kwabavelisi ngenxa yeempawu zayo ezizodwa. Oku kugqiba kubandakanya inkqubo enamanyathelo amabini: i-electroless nickel plating elandelwa kukuntywiliselwa kwegolide.
Iinzuzo ze-EING:
I-Solderability:I-EING ibonelela ngomcaba othe tyaba, nomgangatho ophucula ukuthengiseka, okwenza kube lula ukuncamathisela amacandelo ngexesha lokuhlanganisa.
Ukuxhathisa ukonakala:Uluhlu lwegolide lukhusela i-nickel engaphantsi kwi-oxidation, iqinisekisa ukuthembeka kwexesha elide kwiimeko ezahlukeneyo zokusingqongileyo.
Ukucaba:Umphezulu ogudileyo we-EING ulungele amacandelo alula, axhaphake kakhulu kwizinto zombane zanamhlanje.
Ukuhambelana:I-EING iyahambelana nezixhobo ezahlukeneyo ze-PCB kwaye ingasetyenziswa kwiibhodi ezinemingxuma eyimfama, ukuqinisekisa ukuhlanganiswa okungenamthungo kwezinto zoyilo.
