Iyo ikibaho cya PCB gipakiye vacuum hanyuma kikoherezwa nyuma yubugenzuzi bwa nyuma bwibicuruzwa, kubibaho mu byiciro byabigenewe, abakora inama rusange yumuzunguruko bazakora ibarura ryinshi cyangwa bategure ibice byinshi byabigenewe kubakiriya, hanyuma bapakira vacuum nububiko nyuma ya buri cyiciro cyibicuruzwa Byarangiye.Gutegereza koherezwa.None se kuki ikibaho cya PCB gikenera gupakira vacuum?Nigute wabika nyuma yo gupakira vacuum?Ubuzima bwayo bumara igihe kingana iki?Xiaobian ikurikira yinganda zumuzunguruko wa Xintonglian izaguha intangiriro.
Uburyo bwo kubika ikibaho cya PCB nubuzima bwacyo:
Kuki ikibaho cya PCB gikenera gupakira vacuum?Abakora inama y'ubutegetsi ya PCB baha agaciro gakomeye iki kibazo.Kuberako ikibaho cya PCB kidafunze neza, zahabu yo kwibiza hejuru, amabati hamwe nibice bya padi bizahinduka okiside kandi bigire ingaruka kumasuderi, bidahuye nibikorwa.
None, nigute wabika ikibaho cya PCB?Ikibaho cyumuzunguruko ntaho gitandukaniye nibindi bicuruzwa, ntigishobora guhura numwuka namazi.Mbere ya byose, icyuho cyubuyobozi bwa PCB ntigishobora kwangirika.Mugihe cyo gupakira, igice cya firime ya bubble igomba gukikizwa kuruhande rwagasanduku.Kwinjiza amazi ya firime ya bubble nibyiza, bigira uruhare runini mukwirinda ubushuhe.Birumvikana ko amasaro adafite ubushuhe nayo ntangarugero.Noneho ubitondere kandi ubishyireho ikimenyetso.Nyuma yo gufunga, agasanduku kagomba gutandukanywa nurukuta kandi kakabikwa ahantu humye kandi gahumeka kure yubutaka, kandi bigomba no kurindwa izuba.Ubushyuhe bwububiko bugenzurwa neza kuri 23 ± 3 ℃, 55 ± 10% RH.Mubihe nkibi, imbaho ​​za PCB zivura hejuru nka zahabu yibiza, electro-zahabu, amabati ya spray, hamwe nifeza ya feza birashobora kubikwa mumezi 6.Ikibaho cya PCB hamwe nubuvuzi bwo hejuru nka immersion tin na OSP birashobora kubikwa mumezi 3.
Ku mbaho ​​za PCB zidakoreshwa igihe kinini, nibyiza ko abakora imbaho ​​zumuzunguruko bashushanya irangi ryamabara atatu.Imikorere y'irangi-itatu irashobora gukumira ubushuhe, ivumbi na okiside.Muri ubu buryo, ubuzima bwo kubika ubuyobozi bwa PCB buzongerwa kugeza kumezi 9.
