Pofuna kuthandizira kupanga ndikupanga, pcbpcb madera a Jigsaw nthawi zambiri ayenera kupanga chizindikirocho, v-popanga, ndi kuyendera.
Mapangidwe a PCB
1. Mawonekedwe (mafayilo opumira) njira yopumira ya PCB iyenera kutengera njira yotsekera yotsekedwa kuti muwonetsetse kuti njira yopumira ya PCB siinawonongeke atakhazikika pa mawonekedwe.
2. Mbali yonse ya PCB yopukutira ndi ≤260mm (mzere wa snimens) kapena ≤300mm (fuji pamzere); Ngati chokhacho chimafunikira, kutalika kwathunthu kwa njira ya PCB ndi 125mm × 180mm.
3. Maonekedwe a njira ya PCB ndiyafupi kwambiri ndi lalikulu momwe mungathere, ndipo ndikulimbikitsidwa kugwiritsa ntchito 2 × 2, 3 × 3, ... ndi njira yolowera; Koma sikofunikira kuti mufotokozere mabodi abwino ndi oyipa;
PCBV-Dulani
1. Pambuyo kutsegula v-kudula, makulidwe X / 4 ~ 1/3) Kukula kwapamwamba l, koma makulidwe ocheperako X0.4mm. Zoletsa zimapezeka kuti matabwa okhala ndi katundu wolemera, ndipo malire otsika amapezeka kuti matabwa okhala ndi katundu wopendekera.
2. Chifukwa cha malire ochepera, njira yopumira ya V
Chilemba
1. Mukakhazikitsa mfundo zosankhidwa, nthawi zambiri imasiyanitsa malo osakanikirana 1.5 mm okulirapo kuposa mawonekedwe a kusankha.
2. Pali mfundo ziwiri zosiyanasiyana. Malingaliro oyezera a point yolondola ya PCB yonse nthawi zambiri imakhala chidutswa chimodzi. Malo ophunzitsira apamwamba a PCB; Mlingo woyezera mwa kulingalira moyenera za PCB yamagetsi nthawi zambiri amakhala pakona yapamwamba ya PCB PCB PCB.
3. Zigawo za qfp (lalikulu lathyathyathya) yokhala ndi waya) yokhala ndi BGA (mpira gga (a mpira) wokhala ndi mtengowu)
kukonza mbali yaukadaulo
1. Malire pakati pa chimango komanso gulu lalikulu la bolodi, malowo pakati pa bolodi lalikulu ndi gulu lalikulu siliyenera kukhala lalikulu kapena lalikulu, ndipo m'mphepete mwa madera a PCBbPCB ndi malo osungirako a PCBbCC. Kuonetsetsa kuti ntchito yodulira ya CNC yasintha.
Mabowo olondola pa bolodi
1. Amagwiritsidwa ntchito poyang'ana kwambiri gawo lonse la magemu a PCBCC. Panthawi yovuta, QFP yokhala ndi nthawi yochepera 0,65mm iyenera kuyikidwa pakona yake yapamwamba; Zizindikiro zomveka za PCB mwana wamkazi wa bolodi ayenera kuyikidwa m'magulu awiriawiri ndikuyika pamwamba pazinthu zolondola.
2.
Wopanga PCB wabwino ayenera kuganizira zinthu zopanga ndi kupanga popanga mapulani opanga mafashoni owonetsa kuti awonetsetse kupanga bwino, kusintha zokolola, ndikuchepetsa ndalama zambiri.
