PCB marongerwo mitemo:
1. Mumamiriro ezvinhu akajairika, zvikamu zvose zvinofanira kurongwa panzvimbo imwechete yebhodhi redunhu.Chete kana iyo yepamusoro layer yanyanya kuomarara ndipo panogona kuiswa mimwe michina ine hurefu hushoma uye yakaderera kupisa, senge chip resistors, chip capacitors, uye Chip ICs inoiswa pazasi layer.
2. Pasi pechikonzero chekuvimbisa kushanda kwemagetsi, zvikamu zvinofanira kuiswa pane gridhi uye zvakarongeka zvakafanana kune mumwe nemumwe kana vertically kuitira kuti zvive zvakanaka uye zvakanaka.Kazhinji, zvikamu hazvibvumirwi kupindirana;zvikamu zvinofanira kurongeka zvakabatana, uye zvikamu zvinofanira kurongeka pakugadzirisa kwose.Kugovera kwakafanana uye kuenderana kusimba.
3. Iyo shoma shoma pakati pepadhi padhi maitiro ezvikamu zvakasiyana pabhodhi redunhu inofanira kuva pamusoro pe1MM.
4. Nharaunda kubva kumucheto kwebhodhi redunhu kazhinji haisi pasi pe2MM.Chimiro chakanakisa chebhodhi redunhu irectangle ine aspect ratio ye3:2 kana 4:3.Kana saizi yebhodhi redunhu yakakura kupfuura 200MM ne150MM, bhodhi redunhu rinogona kutakura Mechanical simba.
PCB Dhizaini Mafungiro
(1) Dzivisa kuronga mitsara yakakosha yechiratidzo pamucheto wePCB, senge wachi nekuisazve masaini.
(2) Chinhambwe pakati pechasi pasi waya uye mutsetse wechiratidzo chinenge 4 mm;chengetedza chikamu cheiyo chassis pasi waya isingasviki 5: 1 kuderedza inductance maitiro.
(3) Shandisa iyo LOCK basa kukiya zvishandiso uye mitsara ine zvinzvimbo zvakatemerwa, kuitira kuti zvisazoshorwa mune ramangwana.
(4) Hupamhi hudiki hwewaya hahufanire kunge huri pasi pe0.2mm (8mil).Mune yakakwirira-density uye yakakwirira-chaiyo yakadhindwa maseketi, hupamhi uye nzvimbo yewaya zvinowanzoita 12mil.
(5) Iyo 10-10 uye 12-12 misimboti inogona kushandiswa kune waya pakati peIC pini yeDIP package, kureva, kana waya mbiri dzichipfuura pakati pepini mbiri, dhayamita repadhi rinogona kusetwa ku50mil, uye iyo upamhi hwemutsara uye kupatsanurwa kwemutsara zvese 10mil, kana waya imwe chete ikapfuura pakati pepini mbiri, dhayamita yepedhi inogona kusetwa kusvika 64mil, uye upamhi hwemutsara uye mutsara wemutsara zvese zviri 12mil.
(6) Kana iyo dhayamita yepedhi iri 1.5mm, kuitira kuti uwedzere kupenengura simba repadhi, unogona kushandisa refu denderedzwa padhi nehurefu husingasviki 1.5mm uye hupamhi hwe1.5mm.
(7) Dhizaini Kana mitsetse yakabatana nemapedhi yakaonda, kuwirirana pakati pemapadhi uye mitsara kunofanirwa kugadzirwa muchimiro chekudonhedza, kuitira kuti mapedhi haasi nyore kusvuura uye mitsara nemapedhi hazvisi nyore kubvisa.
(8) Paunenge uchigadzira machira emhangura akakura, panofanira kunge paine mafafitera pamhangura, maburi ekubvisa kupisa anofanira kuwedzerwa, uye mahwindo anofanira kugadzirwa kuita mesh shape.
(9) Pfupisa kubatana pakati pepamusoro-frequency zvikamu zvakanyanya sezvinobvira kuderedza kugovera kwavo paramita uye kupindirana kwemagetsi emagetsi.Zvikamu zvinokonzeresa kukanganisa hazvigone kunge zviri padhuze kune mumwe nemumwe, uye zvinopinda uye zvinobuda zvinofanirwa kuchengetwa zviri kure sezvinobvira.
