PCB Panelmitemo uye nzira
1. Zvinoenderana nezvinodiwa zvemaitiro emafekitori akasiyana egungano, ukuru hwepamusoro uye saizi shoma yepaneru inofanira kunzwisiswa zvakajeka.Kazhinji, PCB idiki pane 80X80mm inoda kuiswa mapaneru, uye saizi yepamusoro inoenderana nekugona kugadzirisa kwefekitori.Muchidimbu, pcb saizi inofanira kusangana nezvinodiwa zveSMT midziyomafittings, ayo anobatsira SMT chigamba kugadzirisa uye kubatsira kusarudza ukobvu hwePCB board.
2. Gungano uye sub-boarding inofanira kusangana nezvinodiwa zveDFM neDFA, uye panguva imwechete iva nechokwadi chokuti gungano rePCB rakagadziriswa uye harina kukanganisa nyore nyore mushure mekuiswa pachigadziro.Iyo inoparadzanisa groove pakati pemapuranga inofanirwa kusangana nezvinodiwa flatness yepasi panguvaPCBAchip processing.
3. MuPCB paneldesign, kurongeka kwezvikamu kunofanira kudzivisa kuparadzanisa kushungurudzika uye kukonzera kuputika kwechikamu.Iko kushandiswa kwepre-scored panel chimiro kunogona kuderedza warpage uye deformation panguva yekuparadzaniswa kwebhodhi, uye kuderedza kushushikana kwezvikamu.Kusvikira zvishoma, edza kusaisa zvakakoshazvikamuinoteverakudivi rekuita.
4. Ukuru uye chimiro chepaneti chinobatwa maererano neprojekti chaiyo, uye chimiro chechimiro chiri pedyo nekona sezvinobvira.Inokurudzirwa zvakanyanya kushandisa iyo 2 × 2 kana 3 × 3 mapaneru nzira.Hazvikurudzirwi kusanganisa yin uye yang panels kana zvisingadiwi;
5. Kana iyo ratidziro yebhodhi yependero yekubatanidza ichipfuura kupindira pakati peakawanda-akabatana mabhodhi, inogadziriswa nekutenderedza iyo yakabatana + process side kudzivirira hurombo husina kunaka hwekukuvara kwekudhumhana panguva yekufambisa kana kubata maitiro.mushure mekuvhara.
6. Mushure mekugadzirwa kwepaneru, inofanirwa kuve nechokwadi kuti mupendero wenzvimbo yekunongedza yebhodhi hombe inosvika 3.5mm kubva kumucheto kwebhodhi (iyo shoma yemuchina unorovera kumucheto kwePCB ndeye 3.5mm. ), uye maviri diagonal referensi mapoinzi pabhodhi hombe haigone kuiswa symmetrically.Usaise mareferensi mapoinzi akaenzana, kuitira kuti reverse/ reverse divi rePCB rikwanise kupinda muchina kuburikidza nebasa rekuzivikanwa remudziyo wacho.
7. Kana ukobvu hwePCB bhodhiiri pasi pe 1.0mm, simba rebhodhi rese repaneru richadzikiswa zvakanyanya (rakapera simba) kana iyo splicing joint kana v-cut groove yawedzerwa, nekuti iyo V-cut yakadzika ndeye 1/3 yebhodhi ukobvu, Pakati pe iyo PCB board inoshandiswa pakusimba, uye chikamu chetsigiro skeleton - girazi fiber jira V rakaputsika, zvichikonzera kupfava kwakakosha kwesimba.Kana ikasatsigirwa nejig, inokanganisa maitiro ari pasi pePCBA.
8. Kana dziripozvigunwe zvegoridhepaPCB, kazhinji isa zvigunwe zvegoridhe kunze kwebhodhi kwakananga kwenzvimbo isina kutsemuka.Mucheto wechigunwe chegoridhe haugone kuiswa kana kugadziriswa.
