PCB inzira yo kwikuramo ibice byinshi

PCB igizwe n'abantu benshi ni inzira ikurikirana.Ibi bivuze ko ishingiro ryurwego ruzaba igice cyumuringa wumuringa hamwe nigice cya prepreg yashyizwe hejuru.Umubare wibice bya prepreg uratandukanye ukurikije ibisabwa mubikorwa.Byongeye kandi, intangiriro yimbere ishyirwa kumurongo wa bileti hanyuma ikuzuzwa na bilet ya prereg itwikiriwe na feza y'umuringa.Laminate ya PC-ibice byinshi PCB ikorwa.Shyira laminates imwe hejuru yundi.Nyuma yumurongo wanyuma wongeyeho, hashyizweho urwego rwa nyuma, rwitwa "igitabo," kandi buri gice cyitwa "umutwe."

Igitabo kirangiye, cyimurirwa mumashini ya hydraulic.Imashini ya hydraulic irashyuha kandi ikoresha igitutu kinini na vacuum mugitabo.Ubu buryo bwitwa gukira kuko bubuza guhuza hagati ya laminate na buriwese kandi bigatuma resin prereg ihuza hamwe ninturusu.Ibigize noneho bivanwaho hanyuma bikonjeshwa mubushyuhe bwicyumba kugirango ibisigazwa biture, bityo birangize gukora uruganda rukora umuringa wa PCB.

Amabati atandukanye amaze gutemwa akurikije ubunini bwagenwe, umubare wimpapuro zitandukanye uratoranywa ukurikije ubunini bwurupapuro kugirango ube icyapa, kandi icyapa cyometseho giteranirizwa mubice bikanda ukurikije uko bikenewe. .Shyira igice cyo gukanda mumashini ya laminating kugirango ukande kandi ukore.

Ibyiciro 5 byo kugenzura ubushyuhe

. igitutu cyose.

(b) icyiciro cyo gukumira: hejuru yubutaka bwakize ku gipimo cyo hasi.Intangiriro yibanze irashyuha kandi igashonga, kandi intera yububiko bwa resin itangira guhurirana.

. intangiriro yibanze, bivamo gutondeka cyangwa gucamo ibicuruzwa byarangiye.

. guhuza hagati yuburyo bwimpapuro zifatika, munsi yigitutu cyumuvuduko kugirango ube wuzuye wuzuye, hanyuma ibicuruzwa byarangiye kugirango ugere ku gaciro keza.

. by'itangazamakuru, rishobora no gukonjeshwa bisanzwe.Iki cyiciro kigomba gukorwa hitawe kumuvuduko wateganijwe, kandi igipimo gikonje gikwiye kugenzurwa.Iyo ubushyuhe bwa plaque bugabanutse munsi yubushyuhe bukwiye, irekurwa ryumuvuduko rirashobora gukorwa.
