Maitiro Ekudzivirira Makomba Asina Mhangura muHigh Aspect Ratio PCBs: Ruzivo Runokosha Pakugadzira PCB
Kunzwisisa Kukosha kweHukuru hweMaburi kusvika paHukobvu muKugadzira PCB
Mukugadzira maPCB, chiyero chehukuru hwegomba nehukobvu, inozivikanwawo se chiyero cheaspect, chinhu chakakosha chinokanganisa kunaka kwekuisa maburi. Chiyero ichi chinoverengerwa nekukamura ukobvu hwePCB nedhayamita yeburi, inowanzonzi chiyero chehurefu kusvika padhayamita (L/D).
Semuenzaniso, kana ukobvu hwePCB huri 1.60 mm uye dhayamita yegomba iri 0.2 mm, chiyero chechikamu ndeche8:1. Chiyero chidiki chechikamu chinoratidza mabhodhi matete ane maburi makuru, izvo zvinowanzoita kuti pave nemigumisiro iri nani yekubatanidza ma ion nekuda kwekugoverwa kwema ion kwakaenzana panguva yekushandiswa kwe electroplating.
Zvisinei, maPCB ane chiyero chepamusoro—avo vane mabhodhi matete nemaburi madiki—vanokonzera matambudziko makuru panguva yekushandiswa kwemagetsi, zvichikonzera zvikanganiso zvakaita se maburi asina mhangura (inozivikanwawo se "blind vias" kana kuti "voids") uye plating isina kunaka.
Chii Chinokonzera Maburi Asina Mhangura muHigh Aspect Ratio PCBs?
- Mabhubhu Madiki uye Kuvharika
Mutsika dzechinyakare electroplating yakananga (DC) Kana zvaitwa, mushonga we electroplating unogona kubata mabhubhu madiki ari mugomba, zvichidzivirira mhangura kuti isaputire madziro emaburi zvakaenzana. Mabhubhu aya anogona kuvharira kuyerera kwemhangura, zvichikonzera nzvimbo dzisina mhangura yakakwana. - Kuchenesa Zvisina Kunaka Panguva Yekurapwa Kwemwana Asati Arapwa
Kana PCB isina kucheneswa zvakanaka isati yaiswa jira, tsvina kana zvasara zvinogona kuramba zviri mumakomba. Izvi zvinodzivirira mhangura kuti isanamatira pamadziro emakomba, zvichiita kuti pave nenzvimbo dzisina kusimba. - Zvikanganiso zveBooresa
Pakuboora maburi ane chiyero chakakwirira, kana chidimbu chekuboora chisina kupinza zvakakwana, chinogona kukonzera matambudziko pamusoro pegomba. Pane kubvisa zvinhu zviri nyore, chidimbu chekuboora chinogona kukweva uye kubvarura resin kana fiberglass, zvichisiya nzvimbo dzakaomarara. Izvi zvinogona kukanganisa maitiro ekuputira uye kutungamira pakunamatira kwemhangura kusina kunaka.
Kuchinja Kwakaita Huwandu hweChimiro Kunokanganisa Sei Hunhu hweKuisa Plating
Zve maPCB ane chiyero chepamusoro (semuenzaniso, 14:1, 16:1, kana kunyange 20:1), maitiro ekuisa plating anova akaoma zvikuru. Mhinduro ye electroplating inonetseka kuisa mhangura zvakaenzana, kunyanya munzvimbo dzemukati dzemaburi, izvo zvinoguma ne mhedzisiro yembwa nepfupaIzvi zvinoreva kuti pamusoro pegomba rinokura nepo chikamu chepazasi chinoramba chakavharirwa pasi.
Pamusoro pezvo, gomba iri kuwanda kwemagetsi emagetsi inosiyana-siyana pamusoro pegomba. Pamusuwo wegomba, huwandu hwemagetsi hwakakwira, nepo muzvikamu zvakadzika, hwakaderera. Kupararira kusina kuenzana uku kunoita kuti pave nekusanyatsoiswa zvakanaka kwesimbi muzvikamu zvepazasi zvegomba, zvichibatsira pakuumbwa kwe maburi asina mhangura.
Mhinduro Dzakadzama Dzekudzivirira Maburi Asina Mhangura muHigh Aspect Ratio PCBs
Kuti vadzivise matambudziko aya, mafekitori emazuva ano ekugadzira maPCB ari kutendeukira ku kuputira kwemoyo tekinoroji, iyo inokunda zvakawanda zvezvipingamupinyi zveDC electroplating yechinyakare.
Pulse Plating yeKuisa Mhangura Yakaenzana
Kuisa ma pulse plating kunoshandisa alternating current ne controlled pulses kuti kuwedzere kushanda zvakanaka kwe copper deposition. Kusiyana ne DC plating yakajairika, kuisa ma pulse plating kunowedzera kufamba kwema ion mukati megomba, zvichiita kuti copper deposit yakaenzana mugomba, pagedhi uye munzvimbo dzakadzika. Izvi zvinoita kuti plating ive nani uye zvinodzivirira kuumbwa kwemaburi asina copper.
Pamusoro pezvo, pulse plating inoita kuti mhangura igare zvakaenzana pasina kuwedzera ukobvu hwemhangura pamusoro pebhodhi, zvichichengetedza kusimba kwemasekete ane density yakakura, mitsetse mitete, uye kupindirana kwakaringana.
Mamwe Maitiro
- Maitiro Akavandudzwa Ekuboorera
Kushandisa mabhora ekudhirowa nemazvo kunogona kuita kuti maburi ave akatsetseka uye akachena, zvichivandudza kunaka kwenzvimbo yacho uye kuona kuti mapurasitiki acho anoshanda zviri nani. - Kurapwa Kusati Kwaitwa Kwakanaka
Kuchenesa nekunyatsogadzirisa maburi ePCB kunogona kuita kuti mhangura inamatire zviri nani. kucheka kwemakemikari kana kuchenesa plasma nzira dzekushandisa dzinogona kubvisa chero tsvina uye kuvandudza kunaka kwemadziro egomba, zvichiita kuti pave nemigumisiro iri nani yeplating. - Kushandisa Midziyo Yepamusoro Yekuputira
Mafekitori emazuva ano ePCB anoshandisa michina yakagadzirirwa kubata maPCB ane aspect ratio yepamusoro. Izvi zvinosanganisira matangi emagetsi akavandudzwa, masisitimu epamusoro ekusefa mhinduro, uye nzira dziri nani dzekudzora mashandiro emagetsi.
Ungagadzira sei gomba riri mumufananidzo uri pazasi?
✅Mhinduro: Richfulljoy's pulsed VCP inogona kudzivirira kuitika kwemakomba nemakomba akawandisa muDC plating. Kushanda zvakanaka kwe current density plating kwakanyanya, uye pasi pe pulse plating system, inogona kuita kuti mukati nekunze kwegomba zvive zvakanaka kwazvo. Kugoverwa kwe coating kunogona kuwanikwa, uye pamusoro pe copper haiwedzere, uye pamusoro pe copper haiwedzere, uye thin circuit uye high-precision impedance zvinogona kuvimbiswa.
Kuvandudza Hunhu muKugadzira PCB Yepamusoro
Mukugadzirwa kwePCB kwakakwirira, kudzivirira maburi asina mhangura Zvakakosha pakuchengetedza kunaka kwechigadzirwa uye mashandiro azvo. Nekunzwisisa matambudziko ane chekuita nekuisa plating mumagadzirirwo ehigh aspect ratio uye kushandisa matekinoroji epamusoro senge kuputira kwemoyo, Vagadziri vePCB vanogona kuve nechokwadi chekuti mapurasitiki acho anoshanda zvakanaka uye akavimbika.
Kana uchibatanidzwa mune Kugadzirwa kwePCB kana kushanda ne Mafekitori ekugadzira maPCB, zvakakosha kuziva nezvemaitiro aya uye kushanda nevagadziri vane hunyanzvi hwekugadzirisa maPCB ane aspect ratio yepamusoro netekinoroji yazvino.
