Serivisi imwe yo gukora ibikoresho bya elegitoroniki, igufasha byoroshye kugera kubicuruzwa byawe bya elegitoronike kuva PCB & PCBA

Wige ibi, isahani ya PCB ntabwo igaragara!

Mugihe cyo gukora imbaho ​​za PCB, ibintu byinshi bitunguranye bizabaho, nkumuringa wa electroplated, umuringa wumuringa, isahani ya zahabu, amabati ya tin-gurşine hamwe nibindi bisate. None niyihe mpamvu yo gutandukana?

Munsi yumucyo wumucyo ultraviolet, fotinitiator ikurura ingufu zumucyo ibora mumatsinda yubuntu itera fotopolymerisation kandi ikora molekile yumubiri idashobora gukemuka mugisubizo cya alkali. Mugihe cyerekanwe, kubera polymerisime ituzuye, mugihe cyiterambere, firime irabyimba kandi yoroshya, bivamo imirongo idasobanutse ndetse na firime igwa, bikaviramo guhuza nabi hagati ya firime numuringa; Niba guhura birenze urugero, bizatera ingorane mumajyambere, kandi bizanatanga umusaruro no gutobora mugihe cyo gufata amasahani, bikora plaque yinjira. Ni ngombwa rero kugenzura ingufu zigaragara; Nyuma yubuso bwumuringa bumaze gutunganywa, igihe cyogusukura nticyoroshye kuba kirekire, kuko amazi yisuku nayo arimo ibintu bimwe na bimwe bya acide, nubwo ibiyirimo bidakomeye, ariko ingaruka zubuso bwumuringa ntizishobora. gufatanwa uburemere, kandi ibikorwa byogusukura bigomba gukorwa hubahirijwe ibisobanuro byakozwe.

Sisitemu yo kugenzura ibinyabiziga

Impamvu nyamukuru ituma igipande cya zahabu kigwa kiva hejuru ya nikel ni uburyo bwo kuvura nikel. Ibikorwa bibi byo hejuru bya nikel biragoye kubona ibisubizo bishimishije. Ubuso bwa nikel biroroshye gukora firime ya passivation mukirere, nko kuvura nabi, bizatandukanya urwego rwa zahabu nubuso bwa nikel. Niba activation idakwiriye muri electroplating, urwego rwa zahabu ruzavanwa hejuru yubutaka bwa nikel hanyuma rukuremo. Impamvu ya kabiri ni uko nyuma yo gukora, igihe cyo gukora isuku ni kirekire cyane, bigatuma firime ya passivation yongeye gushingwa hejuru ya nikel, hanyuma igashyirwaho zahabu, byanze bikunze izana inenge muri kote.

 

Hariho impamvu nyinshi zo gusiba amasahani, niba ushaka gukora ibintu nkibyo mugikorwa cyo gukora amasahani ntibibaho, bifite aho bihurira cyane nubwitonzi ninshingano zabatekinisiye. Kubwibyo, uruganda rwiza rwa PCB ruzakora amahugurwa asanzwe kuri buri mukozi wamahugurwa hagamijwe gukumira itangwa ryibicuruzwa bito.
