- Inzego zishyushye zashyizwe hejuru ya PCB yashongesheje amabati ayobora kandi akishyurwa ahantu hateganijwe (guhuha). Kubikora bigize ikariso irwanya ibimama birashobora gutanga ibyiza. Umusirikare ushyushye n'umuringa bagize couple-sikkim coup uruganda, hamwe n'ubugari bwa 1 kugeza 2mil.
- Indangamuntu kamanda irinda (OSP) muguhinga imbonankubone igikona kama. Iyi filime ya PCB ya Multilayer ifite ubushobozi bwo kunanira okiside, ihungabana ryubushyuhe, nubushuhe kugirango urinde ubuso bwumuringa (okiside cyangwa sulfulisation cyangwa sulfulisation, nibindi) mubihe bisanzwe. Muri icyo gihe, ku bushyuhe bwo gusudira, gusunika amazi bikurwaho byoroshye.
3. Ni-au chemique yatwikiriye hejuru yumuringa hamwe nibyimbye, ni-au ashus theloy Amashanyarazi yo kurinda Inama y'Ubutegetsi Multilayer. Kuva kera, bitandukanye na osp, ikoreshwa gusa nkikibaya cya rustpleof, irashobora gukoreshwa mugukoresha igihe kirekire pcb no kubona imbaraga nziza. Byongeye kandi, ifite kwihanganira ibidukikije ko ibindi bintu byo kuvura hejuru bidafite.
4. Kureka ifeza idafite amashanyarazi hagati ya OSP na Nickel / Gukora zahabu, inzira ya PCB yoroshye kandi yoroshye.
Ibidukikije bishyushye, byishure kandi byanduye biracyatanga imikorere myiza yamashanyarazi no gukundwa neza, ariko kari. Kuberako nta nackeli iyobowe na feza, ifeza yimvura ntabwo ifite imbaraga nziza zumubiri za portale zitagira sital / zahabu.
5 Intego nyamukuru ya Nikel Gutoranya ni ukubuza itandukaniro hagati ya zahabu n'umuringa. Hariho ubwoko bubiri bwa zahabu ya Nikel: zahabu yoroshye (zahabu itunganijwe, bivuze ko itagaragara neza) na zahabu ikomeye (ikomeye, irwanya ibintu byiza). Zahabu yoroshye ikoreshwa cyane mugupakira umurongo wa zahabu; Zahabu ikomeye ikoreshwa cyane muguhuza amashanyarazi.
6. PCB ivanze mu bubiko bwo kuvura hejuru ihitamo uburyo bubiri cyangwa bwinshi bwo kuvura hejuru, inzira zisanzwe ni: nikel zahabu anti-okiside, nikel platique ishyushye Nubwo impinduka muri PCB Mulb Mulb Multilayer inzira ntabwo ikomeye kandi isa nkaho, igomba kumenya ko igihe kirekire cyo guhindura buhoro kizagutera guhinduka gukomeye. Hamwe no gukenera kwiyongera mu kurengera ibidukikije, Ikoranabuhanga ryo kuvura hejuru rya PCB rigomba guhinduka cyane mugihe kizaza.
