1. Kudzivirira Tin-Yakabatanidza Short Circuits
Iyo yekuchengetedza nzvimbo inowirirana zvakanyanya nesimbi mesh yekuwedzera panguva yeSMT chigamba kugadzirisa. Zvinhu zvakadai sesimbi mesh kuvhura saizi, ukobvu, kunetsa, uye deformation zvinogona kukonzera welding kutsauka, zvichitungamira kumapfupi maseketi nekuda kwekuvharwa kwerata.
2. Kufambisa Mashandiro
Nzvimbo yakakwana inogonesa kushanda zvakanaka panguva yekukwesheswa kwemaoko, kusarudza welding, tooling, rework, kuongorora, kuyedzwa, uye kusangana. Kupatsanura kwakakodzera kunopindirana nezvinodiwa nzvimbo yekushanda.
3. Kunzvenga Bridging muChip Components
Component spacing inokanganisa kuvimbika kwegungano. Semuenzaniso, kana ma chip components ari padhuze zvakanyanya, solder paste inogona kukwira kumusoro kwesoldering, ichiwedzera njodzi yebhiriji uye mapfupi maseketi, kunyanya ane zvitete zvidimbu.
4. Safety Spacing sezvo Variable
Component spacing zvinodiwa zvinoenderana nekugona kwemidziyo uye gungano rekugadzira zviyero. DFM software inoshandisa kuomarara kwemazinga — tsvuku, yero, uye girinhi — kuratidza kuchengetedzwa kwemazinga ekuona maparamendi epakati pechikamu.
Zvikanganiso zveUnreasonable Component Layout
- MaConnectors Akaiswa Padyo Zvakanyanya
Zvikamu zvepamusoro semakonitani zvinoda nzvimbo yakakwana. Kuva pedyo kwepedyo kunogona kuita kuti rework isingagoneki mushure mekusangana.
- Diki Spacing Pakati Pemidziyo
Midziyo yakapatsanurwa isingasviki 0.5mm bhiriji rengozi nekuda kwesimbi isina kufanira mesh template dhizaini kana kukanganisa kudhinda. Izvi zvinogona kukonzera mapfupi maseketi uye kuderera kwechigadzirwa kuvimbika.
- Matambudziko ane Yakakura Chikamu Kuiswa
Kuvhara kurongeka kwezvinhu zvakakora zvinogona kuita kuti mushini weSMT udhumanane nezvinhu zvakamboiswa, zvichikonzera nzira dzekuchengetedza uye kumisa mashandiro.
Nyaya Yechidzidzo: Dunhu Dfupi kubva Kusina Kukwana Mupakana
Tsanangudzo yeNyaya
Capacitors C117 uye C118 akaiswa pasi pe 0.25mm kure, zvichiita kuti tini-yakabatana pfupi yedunhu panguva yeSMT chigamba kugadzirwa.
Impact yeDambudziko
- Kushanda kwechigadzirwa kwakakanganiswa nemapfupi maseketi.
- Kugadziridzwa kwebhodhi kuwedzera nzvimbo kwakanonoka kutenderera kwebudiriro.
- Mapfupi mapfupi maseketi anogona kuunza njodzi dzekuchengetedza, zvichikonzera kutadza kwemushandisi uye kurasikirwa kukuru.
Wonderfulpcb DFM Assembly Analysis yeSpacing Detection
Wonderfulpcb DFM inopa yepamusoro chikamu chekuona nzvimbo kudzivirira kusanganisa nyaya. Basa rayo rekuongorora gungano rinoita kuti kutevedzerwe zviyero zvepakati pezvishandiso zvakasiyana, kuderedza njodzi mukugadzirwa kwegungano reSMT.
