Indlela yokufumana umngxuma oyimfama kwibhodi yePCB? Kwintsimi yokuvelisa i-electronics, i-PCB (iBhodi yeSekethe eprintiweyo, ibhodi yesekethe eprintiweyo) idlala indima ebalulekileyo, idibanisa kwaye ixhasa amacandelo ahlukeneyo ombane, ukwenzela ukuba izixhobo zombane zisebenze ngokufanelekileyo. Imingxunya eyimfama yinto eqhelekileyo yoyilo kwimveliso yePCB ukudibanisa iisekethe kumanqanaba ahlukeneyo, kodwa zihlala zinzima ukuzifumana kwaye zijonge. Eli nqaku liza kuchaza indlela yokufumana imingxunya eyimfama kwiibhodi zePCB ukuqinisekisa umgangatho kunye nokuthembeka kwebhodi.
1. Sebenzisa iindlela zokuhlola amehlo
Indlela yokufumana umngxuma oyimfama kwibhodi yePCB? Ukuhlolwa kwamehlo yindlela eqhelekileyo esetyenziselwa ukufumana imingxuma eyimfama kwiibhodi zePCB. Ngokusebenzisa i-microscope enesisombululo esiphezulu, amagcisa anokukhangela ngokusondeleyo kumphezulu we-PCB kwimingxuma enokwenzeka. Ukuphucula ukuqwalaselwa, umthombo okhethekileyo wokukhanya, njengokukhanya kwe-ultraviolet, unokusetyenziselwa ukunceda ukuchonga indawo yomgodi oyimfama.
Ukongezelela, i-microscopes yedijithali kunye neekhamera ezichanekileyo zingasetyenziselwa ukugcina uqwalaselo kwifom yedijithali ukuhlalutya okulandelayo kunye nokurekhoda. Le ndlela ifanelekile kwimveliso yebhetshi encinci kunye nezigaba zophando kunye nophuhliso, kodwa inokuthatha ixesha kwaye isebenze kwimveliso enkulu.
2. Sebenzisa ukufumanisa iX-reyi
Ukuhlolwa kwe-X-reyi yindlela enamandla kakhulu enokusetyenziswa ukufumana imingxuma eyimfama engcwatywe kwiibhodi zePCB. Ibhaqa indawo yomngxuma oyimfama ngokukhanyisa ibhodi yePCB kwaye ibambe umfanekiso weX-reyi obonakalisiweyo. Ngenxa yokugqobhoza kweX-reyi, kunokwenzeka ukubona imingxunya enzulu kunokuba kubonwe umphezulu nje.
Uhlolo lweX-reyi luphawu oluphezulu kwaye lufanelekile kwindawo yemveliso emikhulu. Nangona kunjalo, ifuna izixhobo kunye nokuqeqeshwa kwabaqhubi abanamava, ngoko ke kunokubakho imida malunga neendleko kunye neemfuno zobugcisa.
3. Sebenzisa iteknoloji yokufumanisa ukushisa
Itekhnoloji yokufumanisa i-Thermal yindlela yokusebenzisa izixhobo zokubona ubushushu ukufumana imingxuma eyimfama engcwatywe kwiibhodi zePCB. Kule ndlela, ubukho bokutshisa iimfama bunokubonwa ngokubeka umthombo wobushushu kwelinye icala lebhodi yePCB kunye nokubeka esweni utshintsho lobushushu kwelinye icala. Ngenxa yokuba ukungcwatywa okungaboniyo kuchaphazela ukuqhutyelwa kobushushu, kubonisa iimpendulo ezahlukeneyo zokushisa ngexesha lokubona.
Indlela yokufumana umngxuma oyimfama kwibhodi yePCB? Ukukhetha indlela efanelekileyo kuxhomekeke kwisikali semveliso, uhlahlo lwabiwo-mali kunye neemfuno zobugcisa. Kungakhathaliseki ukuba yeyiphi indlela esetyenziswayo, kuyimfuneko ukuqinisekisa umgangatho kunye nokuthembeka kwebhodi ye-PCB ukuhlangabezana neemfuno zezixhobo zombane. Kwinkqubo yokuvelisa i-PCB, ukukhangela okusebenzayo kwemingxuma eyimfama kubalulekile ukuqinisekisa umgangatho kunye nokuthembeka kwebhodi yesekethe.
