Kazhinji, kugadzirwa kwePCB kunonzi Panelization kuwedzera kushanda kweiyo SMT yekugadzira mutsara. Ndeapi ruzivo anofanirwa kutarisirwa mukati Pcb gungano? Ngatitarisei pazviri.

1. Pcb bhodhi furemu (yekunamatira kumucheto) inofanirwa kutora yakavharwa-chiuno dhizaini kuti ive nechokwadi chekuti pcb bhodhi haizoremara mushure mekunge yagadziriswa pane yechigadziro;

2, pcb bhodhi chimiro padhuze sezvinobvira kukwere, yakakurudzirwa 2 × 2, 3 × 3 …… Jigsaw, asi kwete muYin uye Yang bhodhi;

3, pcb bhodhi upamhi ≤260mm (Siemens mutsetse) kana ≤300mm (Fuji mutsetse); Kana otomatiki kugovera kunodiwa, upamhi × kureba pcb board ≤125mm × 180mm;

4, rimwe nerimwe bhodhi mudiki pcb board rinofanirwa kuve nematanho matatu ekumisikidza, 3≤ aperture ≤6 mm, kumucheto yekumisikidza gomba mukati me1mm haibvumirwe waya kana chigamba;

5, iyo yepakati chinhambwe pakati pekapu diki kudzora pakati pe75mm ~ 145mm;

6, kana uchimisikidza poindi yekumisikidza poindi, kazhinji munzvimbo yekumisidzana yakakomberedza nzvimbo yakavhurika yekutenderera 1.5mm yakakura kupfuura yayo;

7.Panofanira kunge pasina mudziyo muhombe kana chiwedzeredzwa padhuze nepanongedzo pakati pekunze furemu uye yemukati ndiro diki, uye kumucheto kwezvikamu uye pcb bhodhi inofanirwa kuve nenzvimbo yakakura kudarika 0.5mm kuona kushanda kwese kweiyo yekucheka chishandiso;

8. Makomba mana ekumisikidza anovhurwa pamakona mana efuremu rekunze rebhodhi, ine aperture ye4mm ± 0.01mm; Simba regomba rinofanira kunge riine mwero kuti rive nechokwadi chekuti haritsemuke mukuita kwemahwendefa epamusoro uye ezasi; Aperture uye chinzvimbo chakaringana kuve chakakwirira, chakatsetseka gomba pamadziro pasina burr;

9. Pamwechete, QFP ine nzvimbo isingasviki 0.65mm ichaiswa munzvimbo yekudyidzana kwechiratidzo chePCB chese bhodhi yekumisikidza uye yekuisa-yakanaka podhi yekuisa; Iko kumisikidza datum zviratidzo zvePCB sub-mabhodhi anofanirwa kushandiswa ari maviri uye akarongedzwa pane iyo diagonal yezvinzvimbo zvinhu;

10, hombe zvikamu zvinofanirwa kuve nekuisa makoramu kana masosi ekumisikidza, senge I / O interface, maikorofoni, bhatiri interface, micro switch, headphone interface, mota, nezvimwe.
