A. Gutunganya uruganda rwa PCB
1. Esching yarenze umuringa
Umuringa wa electrolytic yakoreshejwe ku isoko muri rusange uruhande rumwe rusubira inyuma (rusanzwe ruzwi ku izina rya file) hamwe na plapy imwe (bizwi nka foil foil). Ihuriro rusange ry'umuringa muri rusange riri muri rusange umuringa umuringa hejuru ya 70um, umutuku wa Foil na 18um. Ibikurikira Ashish Hasiba ahanini nta bangango y'umuringa yanze. Iyo igishushanyo cyumuzunguruko kiruta umurongo wa ETCHING, niba hari umuringa wa file uhinduka ariko ibipimo bya ETCHING ntibihindura, ibi bizatuma umuringa uhinduka mubisubizo birebire.
Kuberako zinc ibanza ibyuma bikora, iyo insinga yumuringa kuri PCB yuzuyemo igisubizo kinini, bizatera uruhande rwinshi rwumurongo, bigatera umurongo uhindagurika ku murongo, bigatera umurongo wo guhinduranya uruhande rumwe kandi utandukanijwe na substrate, ni ukuvuga, insinga z'umuringa.
Ikindi kibazo nuko nta kibazo na PCB cyometseho ibipimo, ariko gukaraba no kumisha ntabwo ari byiza nyuma yo kukikizwa, bigatuma umugozi wumuringa ukikijwe nubuso bwa PCB. Niba bidatunganijwe kuva kera, bizanatera uruhande rwumuringa mwinshi. Umuringa.
Ibi bintu muri rusange byibanda kumirongo yoroheje, cyangwa mugihe ikirere kijimye, inenge zisa zizagaragara kuri PCB yose. Wambure insinga yumuringa kugirango urebe ko ibara ryubuso bwayo hamwe nurwego rufatiro (ubwito bwitwa roughene) bwahindutse, butandukanye numuringa usanzwe. Ibara rya foil riratandukanye. Ibyo ubona ni ibara ry'umuringa w'umwimerere wo hasi, kandi imbaraga za shitingi z'umuringa ku murongo wijimye nazo zirasanzwe.
2. Kugongana kwaho byabereye mubikorwa bya PCB, kandi insinga z'umuringa yatandukanijwe nisuka ingufu zingufu zo hanze
Iyi mikorere mibi ifite ikibazo cyo kugashira, kandi insinga z'umuringa izagaragara cyane, cyangwa ibishushanyo cyangwa ibiranga ingaruka mu cyerekezo kimwe. Kuramo insinga y'umuringa ku gice gifite inenge hanyuma urebe hejuru y'umuringa, urashobora kubona ko ibara ry'isonga ry'ibisanzwe, ntihazabaho ruswa ku nkombe z'umuringa ari ibisanzwe.
3. Igishushanyo mbonera cya PCB
Gushushanya imirongo inanutse hamwe numupira wamaguru wijimye kandi uzatera no kugata hejuru yumuzunguruko no kujugunya umuringa.
B. Impamvu yo kumara
Mubihe bisanzwe, umuringa wa file na preff wef izaba hamwe rwose mugihe kinini cyubushyuhe bukabije bwiminota irenga 30, bityo gukanda ntigushyirwaho iminota irenga 30 Ariko, mugihe cyo kwishora no gufatanya, niba PP yanduye cyangwa umuringa byangiritse cyane, cyangwa ibyapa binini nyuma yo kuragira umuringa hafi yumurongo utari muto.
C. Impamvu zo Kumenyekanisha ibikoresho fatizo:
1. Nkuko byavuzwe haruguru, ibisanzwe bya electrolytic y'umuringa, ibicuruzwa byose byagiye bisingwa cyangwa umuringa ushyizwe ku nkuma. Niba agaciro ka fatizo k'ubwoya ari kamere mugihe cyo gukora umusaruro, cyangwa mugihe ibishuko / umuringa, amashami ya kristu akennye, bigatuma umuringa wanditseho, imbaraga z'umuringa zidahagije. Nyuma yimyanya mibi yafashwe muri PCB, insinga z'umuringa izagwa kubera ingaruka zimbaraga zo hanze mugihe zicomeka muruganda rwa elegitoroniki. Ubu bwoko bw'umuringa bukennye ntibuzagira ruswa igaragara iyo ikuramo insinga yo kureba hejuru y'umuringa (ni ukuvuga ubuso bw'inyabukuru), ariko imbaraga za file yumuringa zose zizaba umukene cyane.
2. Guhuza nabi umuringa hamwe na resin: bamwe bashizeho imitungo yihariye, nkimpapuro za htg, kuko sisitemu ya resin ikoreshwa na polekile ya resin yoroshye. Urwego rwo guhura ni hasi, kandi ni ngombwa gukoresha umuringa hamwe nimpinga idasanzwe kugirango uhuze. Umuringa wakoreshejwe mugukora laminates ntabwo ahuye na sisitemu ya resin, bikavamo imbaraga zidahagije zurupapuro rwicyuma-cyuma cyijimye.
