4 Layeri ENIG Impedance Igenzura Umuringa Ukomeye PCB
Ibyitonderwa Kubushakashatsi Bwubushakashatsi Bwumuringa Ukomeye PCB
Hamwe niterambere ryikoranabuhanga rya elegitoronike, ingano ya PCB ni ntoya kandi ntoya, ubucucike buragenda burushaho kuba bwinshi, kandi ibice bya PCB byiyongera, bityo, bisaba PCB kumiterere ihuriweho, ubushobozi bwo kurwanya kwivanga, inzira nibisabwa bikenewe ni byinshi kandi hejuru, nkibiri mubishushanyo mbonera cyane, cyane cyane kubikorwa byumuringa uremereye wa PCB, gukora ubukorikori no kwizerwa mubikorwa byubwubatsi, bigomba kumenyera igishushanyo mbonera kandi byujuje ibisabwa mubikorwa byo gukora, gukora igishushanyo mbonera ibicuruzwa neza.
1. Kunoza uburinganire n'ubwuzuzanye bw'imbere y'umuringa
. ubunini bw'isahani kandi bigira ingaruka kumyanya ikurikira.
.Igice cyimbere cyo gukwirakwiza umuringa ntabwo gisa, kandi urupapuro rwibicuruzwa biroroshye kubaho.
Ibibazo byavuzwe haruguru bigomba kunozwa mugushushanya ibicuruzwa, hashingiwe ku kutagira ingaruka ku mikorere n’imikorere y’ibicuruzwa, urwego rwimbere rw’ahantu hatarimo umuringa hashoboka.Igishushanyo mbonera cy'umuringa hamwe n'umuringa, cyangwa guhindura ubuso bunini bw'umuringa ukabishyira hejuru y'umuringa, guhuza inzira, gukora uburinganire bwacyo, guhuza neza, gukora imiterere rusange yibibaho bihuje kandi byiza.
2. Kunoza igipimo cyumuringa gisigaye cyimbere
Hamwe no kwiyongera kwuburebure bwumuringa, ikinyuranyo cyumurongo ni cyimbitse.Kubijyanye nigipimo kimwe gisigara cyumuringa, ingano yo kuzuza resin igomba kwiyongera, birakenewe rero gukoresha impapuro nyinshi zakize igice kugirango zuzuze kole.Iyo resin ari nkeya, biroroshye kuganisha kubura lame lamination hamwe nuburinganire bwubunini bwisahani.
Igipimo gito cyumuringa gisigaye gisaba umubare munini wa resin kugirango wuzuze, kandi resin igenda ni mike.Mubikorwa byumuvuduko, ubunini bwurwego rwa dielectric hagati yumuringa wumuringa, agace k'umurongo hamwe nubutaka bwa substrate bifite itandukaniro rinini (ubunini bwurwego rwa dielectric hagati yumurongo ni muto cyane), byoroshye kuganisha kuri kunanirwa kwa HI-POT.
Kubwibyo rero, igipimo gisigaye cyumuringa kigomba kunozwa uko bishoboka kwose mugushushanya umuringa uremereye wumuringa PCB, kugirango bigabanye gukenera kuzuza kole, kugabanya ingaruka zokwizerwa zo kuzuza kole yuzuye kutanyurwa no kurwego ruciriritse.Kurugero, ingingo zumuringa hamwe nigishushanyo mbonera cyumuringa gishyirwa ahantu h'umuringa.
3. Ongera ubugari bwumurongo n'umurongo utandukanijwe
Kumuringa uremereye PCBs, kongera umurongo wubugari bwumurongo ntibifasha gusa kugabanya ingorane zo gutunganya ibiti, ariko kandi bifite iterambere ryinshi mukuzuza kole yuzuye.Umwenda wa fibre fibre yuzuyemo umwanya muto ni muto, kandi umwenda wa fibre fibre yuzuye umwanya munini ni byinshi.Umwanya munini urashobora kugabanya umuvuduko wo kuzuza kole yuzuye.
4. Hindura neza igishushanyo mbonera cy'imbere
Kumuringa uremereye PCB, kubera ko uburebure bwumuringa ari mwinshi, hiyongereyeho hejuru yuburinganire, umuringa wabaye mubunini bunini, mugihe cyo gucukura, guterana ibikoresho byimyitozo kumwanya muremure biroroshye kubyara imyenda yimyitozo , hanyuma bikagira ingaruka kumiterere yurukuta rwumwobo, kandi bikagira ingaruka kumyizerere yibicuruzwa.Kubwibyo, murwego rwo gushushanya, urwego rwimbere rwibipapuro bidakora bigomba kuba bike nkibishoboka, kandi ntibisabwa kurenza ibice 4.
Niba igishushanyo kibyemereye, ibice byimbere bigomba kuba binini uko bishoboka.Udupapuro duto tuzatera impagarara nyinshi mugikorwa cyo gucukura, kandi umuvuduko wo gutwara ubushyuhe urihuta mugikorwa cyo gutunganya, byoroshye kuganisha kumuringa Angle yamenetse mumapaki.Ongera intera iri hagati yimbere yimbere yigenga nurukuta rwumwobo nkuko igishushanyo kibyemerera.Ibi birashobora kongera intera itekanye hagati yumuringa wumuringa nu gipande cyimbere, kandi bikagabanya ibibazo biterwa nubwiza bwurukuta rwumwobo, nka micro-ngufi, kunanirwa kwa CAF nibindi.
