Iyo magetsi yekuchengetedza nzvimbo inonyanya kuenderana nehuwandu hwefekitori yekugadzira ndiro, iyo inowanzoita 0.15mm.Kutaura zvazviri, inogona kunge iri pedyo.Kana dunhu risingaenderane nechiratidzo, chero bedzi pasina pfupi pfupi uye ikozvino yakakwana, yakakura ikozvino inoda kukora wiring uye spacing.
1.Distance pakati waya
Chinhambwe chiri pakati pemakondakita chinoda kutariswa zvichibva pakugona kugadzira kwemugadziri wePCB.Zvinokurudzirwa kuti chinhambwe chiri pakati pemakondakita chingangoita 4mil.Nekudaro, mamwe mafekitori anogona zvakare kugadzira ane 3/3mil mutsara wakafara uye mutsara wemitsara.Kubva pakuona kwekugadzirwa, hongu, iyo yakakura zviri nani pasi pemamiriro ezvinhu.Iyo yakajairika 6mil ndiyo yakajairika.
2.Spacing pakati pedhi newaya
Nharaunda pakati pepedhi nemutsara kazhinji haisi pasi pe4mil, uye yakakura chinhambwe pakati pepedhi nemutsara kana paine nzvimbo, zviri nani.Nekuti pad welding inoda kuvhurwa kwehwindo, kuvhurwa kwehwindo kwakakura kupfuura 2mil yepadhi.Kana nzvimbo yacho isina kukwana, haizongokonzeresa kupfupika kwemutsara wemutsara, asi zvakare kutungamirira kune kuratidzwa kwemhangura yemutsara.
3.Kupatsanurana pakati pePad nePad
Nharaunda pakati pepedhi nepedhi inofanira kunge yakakura kudarika 6mil.Zvakaoma kuita solder stop-welding bhiriji isina kukwana pad spacing, uye IC padhi yemataneti akasiyana inogona kunge iine dunhu diki kana welding yakavhurika weld zambuko.Nharaunda pakati petiweki padhi uye padhi idiki, uye hazvina kunaka kuparadzanisa zvakagadziridzwa zvikamu mushure mekunge tini yanyatsobatanidzwa pane welding.
4.Copper nemhangura, waya, PAD spacing
Nharaunda pakati peganda remhangura mhenyu uye mutsara uye PAD yakakura kupfuura iyo pakati pezvimwe zvinhu zvemutsetse, uye chinhambwe pakati peganda remhangura nemutsetse uye PAD yakakura kupfuura 8mil kufambisa kugadzirwa nekugadzira.Nokuti ukuru hweganda remhangura hazvidi kuita zvakakosha, zvishoma zvishoma uye zviduku hazvina basa.Kuti uvandudze goho rekugadzirwa kwezvigadzirwa, nzvimbo pakati pemutsara nePAD kubva paganda remhangura inofanira kunge yakakura sezvinobvira.
5.Spacing yewaya, PAD, mhangura neplate edge
Kazhinji, chinhambwe chiri pakati pewaya, padhi uye ganda remhangura uye mutsara wecontour unofanirwa kunge wakakura kupfuura 10mil, uye isingasviki 8mil inotungamira mukuratidzwa kwemhangura pamucheto weplate mushure mekugadzirwa nekuumbwa.Kana mupendero weplate iri V-CUT, ipapo nzvimbo yacho inofanira kunge yakakura kupfuura 16mil.Waya nePAD haingori mhangura chete yakafumurwa zviri nyore, mutsara uri padyo nekumucheto kwendiro inogona kunge iri diki, zvichikonzera matambudziko ekutakura azvino, PAD diki inokanganisa welding, zvichikonzera kushata.`
