Kurwanya gukurikiranwa kwumuringa wambaye umuringa laminate mubisanzwe bigaragazwa nigereranya ryikigereranyo (CTI).Mubintu byinshi biranga umuringa wambaye umuringa (umuringa wambaye umuringa wa laminates mugihe gito), gukurikirana ukurwanya, nkigipimo cyingenzi cyumutekano no kwizerwa, wagiye uhabwa agaciro na Ikibaho cyumuzunguruko wa PCB abashushanya n'abashinzwe kuyobora imizunguruko.

Agaciro CTI kageragejwe hakurikijwe uburyo busanzwe bwa IEC-112 "Uburyo bwo Kwipimisha Kugereranya Ikigereranyo cyo Gukurikirana Ikigereranyo cya Substrates, Ikibaho cyacapwe hamwe n’Inteko zicapuwe", bivuze ko ubuso bwa substrate bushobora kwihanganira ibitonyanga 50 bya 0.1% bya amonium chloride The agaciro gakomeye cyane (V) aho igisubizo cyamazi kidakora ibimenyetso byamashanyarazi.Ukurikije urwego rwa CTI rwibikoresho, UL na IEC babigabanyijemo amanota 6 n amanota 4.

Reba Imbonerahamwe 1. CTI≥600 nicyiciro cyo hejuru.Umuringa wambaye umuringa ufite indangagaciro za CTI zikunda gukurikiranwa igihe zikoreshejwe igihe kirekire ahantu habi nko umuvuduko mwinshi, ubushyuhe bwinshi, ubushuhe, n’umwanda.

Mubisanzwe, CTI yimpapuro zisanzwe zishingiye kumuringa wambaye laminates (XPC, FR-1, nibindi) ni 50150, naho CTI yumuringa usanzwe ushingiye kumuringa wambaye laminates (CEM-1, CEM-3) hamwe na fibre isanzwe yibirahure. imyenda ishingiye ku muringa yambaye laminates (FR-4) Iva kuri 175 kugeza 225, idashobora kuba yujuje ibyangombwa bisabwa by’umutekano by’ibikoresho bya elegitoroniki n’amashanyarazi.

Mubisanzwe IEC-950, isano iri hagati ya CTI yumuringa wambaye umuringa laminate na voltage ikora ya icyapa cyumuzunguruko kandi intera ntoya (Intera ntarengwa ya Creepage) nayo iteganijwe.Umuyoboro mwinshi wa CTI wambaye laminate ntabwo ukwiranye gusa n’umwanda mwinshi, Irakwiriye kandi cyane cyane kubyara imbaho ​​ziciriritse zicapishijwe imashanyarazi zikoreshwa cyane.Ugereranije n'umuringa usanzwe wambaye laminate hamwe no gukurikiranwa gukomeye gukurikiranwa, umurongo utandukanya imbaho ​​zumuzingo zacapwe zakozwe hamwe nizambere zirashobora kwemererwa kuba nto.

Gukurikirana: Inzira yo gukora buhoro buhoro inzira iyobora hejuru yikintu gikomeye gikingira munsi yibikorwa bihuriweho n'umuriro w'amashanyarazi na electrolyte.

Kugereranya Ikurikiranwa (CTI): Agaciro keza cyane aho ubuso bwibintu bushobora kwihanganira ibitonyanga 50 bya electrolyte (0.1% ya amonium chloride yo mu mazi) bitagize ibimenyetso byerekana, muri V.

Icyemezo cyo gukurikirana ibimenyetso (PTI): Kwihanganira agaciro k'umubyigano aho ubuso bwibikoresho bushobora kwihanganira ibitonyanga 50 bya electrolyte bitagize ibimenyetso byerekana imyanda, byagaragaye muri V.

Ikigereranyo cya CTI kugereranya umuringa wambaye laminate

Kongera CTI yibikoresho byurupapuro ahanini bitangirana na resin, kandi bikagabanya genes zoroha karubone kandi byoroshye kubora mubushuhe muburyo bwa molekuline.
