I-PCB (ibhodi yesekethe eprintiweyo) licandelo eliyimfuneko kwisixhobo sombane, esidibanisa amacandelo e-elektroniki ngemigca yokuqhuba kunye namanqaku okudibanisa. Kuyilo PCB kunye nenkqubo yokuvelisa, imingxunya metallized kunye ngokusebenzisa imingxunya iintlobo ezimbini eziqhelekileyo imingxunya, kwaye nganye inemisebenzi eyodwa kunye neempawu. Oku kulandelayo lucazululo oluneenkcukacha umahluko phakathi PCB metallized imingxunya kunye ngokusebenzisa imingxunya.
Imingxunya enesinyithi
Imingxuma enyityilisiweyo yimingxuma kwinkqubo yokwenziwa kwe-PCB eyenza umaleko wesinyithi kudonga lomngxuma nge-electroplating okanye i-chemical plating. Lo maleko wentsimbi, odla ngokwenziwa ngobhedu, uvumela umngxuma ukuba uqhube umbane.
Iimpawu zemingxuma enesinyithi:
1.Ukuqhuba koMbane:Kukho umaleko wentsimbi oqhubayo eludongeni lomngxuma owenziwe ngesinyithi, ovumela umsinga ukuba uqukuqele ukusuka kwelinye umaleko ukuya komnye ngomngxuma.
2.Ukuthembeka:Imingxunya eyenziwe ngesinyithi ibonelela ngoqhagamshelo olululo lombane kwaye yandise ukuthembeka kwePCB.
3.Ixabiso:Ngenxa yenkqubo eyongezelelweyo yokucwenga efunekayo, ixabiso lemingxuma eyenziwe ngesinyithi idla ngokuba phezulu kunaleyo yemingxuma engenziwanga ngesinyithi.
4. Inkqubo yokuvelisa:Ukwenziwa kwemingxunya eyenziwe ngesinyithi kubandakanya inkqubo yokufakwa kwe-electroplating entsonkothileyo okanye inkqubo yokufakwa kwe-electroless.
5.Isicelo:Imingxunya enyityilisiweyo idla ngokusetyenziswa kwi-PCBS enomaleko amaninzi ukuphumeza uqhagamshelo lombane phakathi kweeleya zangaphakathi
Izinto eziluncedo kwimingxuma enesinyithi:
1.Uqhagamshelwano lwemigangatho emininzi:Imingxunya enyityilisiweyo ivumela ukudityaniswa kombane phakathi kwe-PCBS enemigangatho emininzi, inceda ukuphumeza uyilo oluntsonkothileyo lwesekethe.
2.Imfezeko yomqondiso:Ekubeni umngxuma we-metalized unika indlela efanelekileyo yokuqhuba, inceda ukugcina ingqibelelo yomqondiso.
3.Umthamo wangoku wokuthwala:Imingxuma enyityilisiweyo inokuthwala imisinga emikhulu kwaye ifanele ukusetyenziswa kwamandla aphezulu.
Ukungalunganga kwimingxuma eyenziwe ngesinyithi:
1.Ixabiso:Iindleko zokwenziwa kwemingxunya eyenziwe ngentsimbi ziphezulu, ezinokunyusa ixabiso lilonke lePCB.
2.Ukuntsokotha kwemveliso:Inkqubo yokwenziwa kwemingxuma enesinyithi inzima kwaye ifuna ulawulo oluchanekileyo lwenkqubo yokucwenga.
3.Ubukhulu bodonga lomngxuma:Ukufakwa kwesinyithi kunokunyusa ububanzi bomngxuma, kuchaphazela uyilo kunye noyilo lwePCB.
Ngemingxuma
Umngxuma wokutyhutyha ngumngxuma othe nkqo kwi-PCB ongena kuyo yonke ibhodi ye-PCB, kodwa ayenzi umaleko wesinyithi kudonga lomngxuma. Imingxunya isetyenziselwa ukufakelwa komzimba kunye nokulungiswa kwamacandelo, kungekhona ukudibanisa kombane.
Iimpawu zomngxunya:
1.Ayiqhubeki:umngxuma ngokwawo awuboneleli uxhulumaniso lombane, kwaye akukho luhlu lwetsimbi eludongeni lomngxuma.
2.Unxibelelwano lomzimba:Ngokusebenzisa imingxunya isetyenziselwa ukulungisa amacandelo, afana namacandelo e-plug-in, kwi-PCB ngokudibanisa.
3.Ixabiso:Iindleko zokwenziwa kwemingxuma zihlala zingaphantsi kunezo zemingxuma enesinyithi.
4. Inkqubo yokuvelisa:Ngokusebenzisa inkqubo yokuvelisa umngxuma ilula ngokwentelekiso, akukho nkqubo yokucwenga efunekayo.
5.Isicelo:Ngokusebenzisa imingxunya isoloko isetyenziselwa enye - okanye i-PCBS ene-double-layer, okanye ukufakwa kwecandelo kwi-PCBS enomaleko amaninzi.
Izinto ezilungileyo zomngxunya:
1. Ukusebenza kweendleko:Iindleko zokwenziwa komngxuma ziphantsi, nto leyo inceda ukunciphisa iindleko zePCB.
2.Uyilo olwenziwe lula:Ngokusebenzisa imingxunya yenza lula uyilo lwe-PCB kunye nenkqubo yokuvelisa kuba ayifuni plating.
3.Ukufakwa kwecandelo:Ngemingxuma ibonelela ngendlela elula nesebenzayo yokufakela kunye nokukhusela amacandelo eplagi.
Ububi bemingxuma yokudlula:
1.Uthintelo loqhagamshelwano lombane:Umngxuma ngokwawo awuboneleli uxhulumaniso lombane, kwaye i-wiring eyongezelelweyo okanye i-pad iyadingeka ukufezekisa uxhumano.
2.Unyino losasazo lomqondiso:Imingxuma yokudlula ayifanelekanga kwizicelo ezifuna iileya ezininzi zoqhagamshelo lombane.
3.Umlinganiselo wohlobo lwecandelo:Umngxuma wokutyhutyha usetyenziswa ikakhulu kufakelo lwamalungu eplagi kwaye ayifanelanga amacandelo aphezu komhlaba.
Isiphelo:
Imingxuma enyityilisiweyo kunye nemingxuma ephumayo idlala iindima ezahlukeneyo kuyilo lwePCB kunye nokwenza. Imingxuma enesinyithi inika uxhulumaniso lombane phakathi kweengqimba, ngelixa i-through-holes isetyenziselwa ukufakwa ngokomzimba kwamacandelo. Uhlobo lomngxuma olukhethiweyo luxhomekeke kwiimfuno ezithile zesicelo, ukuqwalaselwa kweendleko, kunye nobunzima boyilo.
