Chii chinonzi pcba bvunzo

PCBA patch process process yakaoma kwazvo, inosanganisira PCB board kugadzira process, chikamu chekutenga uye kuongorora, SMT chigamba musangano, DIP plug-in, PCBA kuyedzwa uye mamwe maitiro akakosha. Pakati pavo, PCBA bvunzo ndiyo inonyanya kukosha yemhando yekudzora chinongedzo mune yese PCBA yekugadzirisa maitiro, iyo inosarudza yekupedzisira kuita kwechigadzirwa. Saka ndedzipi PCBA bvunzo mafomu? Chii chinonzi pcba bvunzo

1, ICT bvunzo inonyanya kusanganisira yedunhu pa-off, voltage uye zvazvino kukosha uye wave curve, amplitude, ruzha, nezvimwe.

2, FCT bvunzo inoda kuita IC chirongwa kupfura, kutevedzera mashandiro ePCBA board yese, kutsvaga matambudziko muhardware uye software, uye yakashongedzerwa neinodiwa chigamba kugadzirisa kugadzirwa kwekugadzirisa uye bvunzo rack.

3, bvunzo dzekuneta kunonyanya kuenzanisira PCBA bhodhi, uye kuita yakakwira-frequency uye kwenguva refu kushanda kweiyo basa, tarisa kana kutadza kuchiitika, kutonga mukana wekutadza muyedzo, uye mhinduro yekushanda kwePCBA. bhodhi mune zvigadzirwa zvemagetsi.

4, bvunzo munzvimbo dzakaomarara inonyanya kufumura bhodhi rePCBA kune tembiricha, humidity, kudonha, splash, vibration yemutengo wemuganho, kuwana mhedzisiro yebvunzo yemasampuli asina kujairika, kuitira kuti ape kuvimbika kwePCBA board yese. batch.

5, kuchembera bvunzo kunonyanya kusimba PCBA bhodhi uye zvigadzirwa zvemagetsi kwenguva yakareba, ramba uchishanda uye tarisa kana paine kukundikana, mushure mekuchembera bvunzo zvigadzirwa zvemagetsi zvinogona kutengeswa mumatche.PCBA maitiro akaoma, mukugadzirwa uye kugadzirisa maitiro, panogona kunge paine matambudziko akasiyana nekuda kwemidziyo isina kufanira kana kushanda, haigone kuvimbisa kuti zvigadzirwa zvinogadzirwa zvinokodzera, saka zvinodikanwa kuita PCB bvunzo kuona kuti chigadzirwa chimwe nechimwe hachizove nematambudziko emhando.

Nzira yekuedza pcba

PCBA bvunzo dzakajairika nzira, pane kunyanya dzinotevera:

1. Kuedza nemaoko

Manual test ndeyekuvimba zvakananga nechiratidzo kuyedza, kuburikidza nechiratidzo uye kuenzanisa kusimbisa kuiswa kwezvikamu paPCB, iyi tekinoroji inoshandiswa zvakanyanya. Zvisinei, nhamba huru uye zvikamu zviduku zvinoita kuti nzira iyi ive shoma uye isingakodzeri. Uyezve, kumwe kukanganisa kwekushanda hakusi nyore kuonekwa uye kuunganidza data kwakaoma. Nenzira iyi, dzimwe nzira dzekuongorora nyanzvi dzinodiwa.

2, otomatiki Optical kuongorora (AOI)

Otomatiki yekuona yekuona, inozivikanwawo seye otomatiki yekuona bvunzo, inoitwa neyakakosha detector, inoshandiswa isati yasvika uye mushure me reflux, uye polarity yezvikamu zviri nani. Zviri nyore kutevera kuongororwa inzira yakajairika, asi nzira iyi haina kunaka yekuzivikanwa kwedunhu pfupi.

3, kubhururuka tsono bvunzo muchina

Kuyedzwa kwetsono kwakawana mukurumbira mumakore mashoma apfuura nekuda kwekufambira mberi mukurongeka kwemuchina, kumhanya, uye kuvimbika. Mukuwedzera, kudiwa kwemazuva ano kwechirongwa chekuedza nekukurumidza kutendeuka uye jig-isina simba rinodiwa pakugadzirwa kwePrototype uye kugadzirwa kwakaderera kunoita kuti kuongorora tsono inobhururuka ive sarudzo yakanakisisa.4. Kuedza kushanda

Iyi inzira yekuyedza yePCB chaiyo kana imwe unit, iyo inoitwa nemichina yakasarudzika. Kune marudzi maviri makuru ekuedza kushanda: Final Product Test uye Hot Mock-up.

5. Manufacturing Defect Analyzer (MDA)

Mabhenefiti makuru eiyi nzira yekuyedza yakaderera kumberi mutengo, yakakwira kuburitsa, nyore kutevera kuongororwa uye nekukurumidza kupfupika kupfupi dunhu uye yakavhurika yedunhu kuyedzwa. Chakashata ndechekuti kuyedzwa kwekushanda hakugone kuitwa, kazhinji hapana chiratidzo chekuvhara bvunzo, chigadziriso chinofanira kushandiswa, uye mutengo webvunzo wakakwira.

pcba bvunzo midziyo

Yakajairika PCBA bvunzo michina ndeiyi: ICT yepamhepo tester, FCT inoshanda bvunzo uye kuchembera bvunzo.

1, ICT online tester

ICT ndeye otomatiki on-line tester, ine huwandu hwakasiyana hwekushandisa uye iri nyore kushanda. ICT otomatiki pamhepo detector inonyanya kugadzirwa dhizaini, inogona kuyera kuramba, capacitance, inductance, integrated circuit. Inonyanya kushanda pakuona dunhu rakavhurika, dunhu diki, kukuvara kwechikamu, nezvimwe, nzvimbo yekukanganisa chaiyo, kugadzirisa nyore.

2. FCT inoshanda bvunzo

FCT basa bvunzo ndeyekupa simulation inoshanda nharaunda senge kunakidzwa uye kuremerwa kwePCBA bhodhi, uye kuwana akasiyana ematunhu maparamendi ebhodhi kuti aone kana anoshanda maparamendi ebhodhi anosangana nezvinodiwa zvekugadzira. FCT inoshanda bvunzo zvinhu zvinonyanya zvinosanganisira voltage, zvazvino, simba, simba chinhu, frequency, basa kutenderera, kupenya uye ruvara, kuzivikanwa kwehunhu, kucherechedzwa kwezwi, kuyera tembiricha, kuyera kudzvanywa, kufambisa kwekufamba, FLASH uye EEPROM kupisa.

3. Kuchembera bvunzo

Muedzo wekuchembera unoreva maitiro ekuenzanisa zvinhu zvakasiyana zvinosanganisirwa mumamiriro chaiwo ekushandiswa kwechigadzirwa kuita zvinoenderana nemamiriro ekusimudzira kuyedza. Bhodhi rePCBA rezvigadzirwa zvemagetsi rinogona kushandiswa kwenguva yakareba kutevedzera kushandiswa kwevatengi, kupinza/kubuda bvunzo kuona kuti kuita kwayo kunosangana nezvinodiwa nemusika.

Aya marudzi matatu emidziyo yekuyedza akajairika muPCBA maitiro, uye PCBA kuyedzwa muPCBA kugadzirisa maitiro kunogona kuona kuti PCBA board inounzwa kumutengi inosangana nezvinodiwa nevatengi dhizaini uye inoderedza zvakanyanya mwero wekugadzirisa.
