5 yakakosha PCB panelization dhizaini matipi ePCB Assembly

Mukuita kuungana kwePCB, tichada michina yeSMT yekunamira zvinhu paPCB.Asi sezvo saizi yega yega yePCB, chimiro kana zvikamu zvakasiyana, kuitira kuti zvigadzirise zvirinani kuSMT kuunganidza maitiro, kunatsiridza kugona uye kuderedza mutengo wegungano.NdosakaPCB musangano mugadziriinoda kumisikidza panelization yePCB.PCBFuture inokupa 5 guildlines yePCB yako panelization kuti ive nani PCB gungano.

Mazano 1: Saizi yePCB

Tsanangudzo: Saizi yePCB inogumira nekugona kwemagetsi ekugadzira ekugadzira mutsara michina.Naizvozvo, saizi yePCB inofanirwa kutariswa patinenge tichigadzira mhinduro dzechigadzirwa.

(1) Iyo yakakura PCB saizi inogona kuiswa paSMT PCB dhizaini yegungano zvinoenderana neyakajairwa saizi yePCB, yakawanda saizi i20 ″ × 24 ″, iyo njanji yakafara 508mm × 610mm.

(2) Saizi yatinokurudzira inoenderana nemidziyo yeSMT PCB board line.Inobatsira pakugadzirwa kwechigadzirwa chega chega uye inobvisa bhodhoro remidziyo.

(3) Kune madiki-saizi maPCB, isu tinofanirwa kugadzirwa se splicing board kuti tivandudze kugadzirwa kwemutsetse wese wekugadzira.

Zvido zvekugadzira:

(1) Kazhinji, ukuru hwepamusoro hwePCB hunofanira kugumira kune huwandu hwe460mm×610mm.

(2) Iyo yakakurudzirwa saizi renji ndeye (200 ~ 250) × (250 ~ 350) mm, uye chikamu chinofanirwa kunge chiri pasi pe2.

(3) Kune maPCB ane saizi isingasviki 125mm×125mm, iyo PCB inofanira kupatsanurwa kune saizi yakakodzera.

Mazano echipiri: Chimiro chePCB

Tsanangudzo: Midziyo yekuunganidza yeSMT inoshandisa njanji kuendesa maPCB, uye haigone kutamisa maPCB asina kurongeka, kunyanya maPCB ane maburi mumakona.

Zvido zvekugadzira:

(1) Chimiro chePCB chinofanira kunge chiri chikwere chenguva dzose chine makona akatenderedzwa.

(2) Kuti ive nechokwadi chekugadzikana kweiyo nzira yekutapurirana, iyo isina kuumbwa PCB inofanirwa kushandurwa kuita skweya yakajairwa nekupatsanura, kunyanya mapeji epakona anofanirwa kuzadzwa kuitira kudzivirira kuti wave soldering iri kusungirirwa neshaya. uye zvozoita kuti bhodhi rizadzwe panguva yekuendesa.

(3) Iyo yakachena SMT bhodhi inotenderwa kuve nemapundu, asi iyo gap saizi inofanira kunge isingasviki chikamu chimwe muzvitatu chehurefu hwedivi raanowanikwa.Kune avo vasingazadzise chinodiwa ichi, isu tinofanirwa kugadzira hurefu hwemaitiro ekugadzira.

(4) Pamusoro pekugadzirwa kwechigunwe chegoridhe, mipendero pamativi ese echipimo inofanirawo kukwizwa (1 ~ 1.5) × 45 ° kufambisa kupinza.

Mazano 3: Iyo PCB yekushandisa stips (PCB miganhu)

Tsanangudzo: Saizi yePCB boarders pane zvinodikanwa zvekutakura njanji yemidziyo.Zvakadai se: michina yekudhinda, michina yekuisa uye reflow soldering mavira.Ivo vanowanzodikanwa kuendesa mupendero (Border) pamusoro pe3.5mm.

Zvido zvekugadzira:

(1) Kuti uderedze deformation yePCB panguva yekutengesa, iyo yakareba yedivi nzira yeiyo isina kuisirwa PCB inowanzoshandiswa senzira yekufambisa.Uye iyo splice PCB, iyo yakareba yedivi nzira inofanirwa kushandiswawo senzira yekufambisa.

(2) Kazhinji, mativi maviri ePCB kana splice PCB yekufambisa nzira anoshandiswa seyekufambisira divi (PCB miganhu).Hudiki hwehupamhi hwePCB miganhu ndeye 5.0mm.Panofanira kunge pasina zvikamu kana majoini ekutengesa kumberi nekumashure kwedivi rekutapurirana.

(3) Kudivi risiri rekutapurirana, hapana chinorambidzwa muSMT PCB musanganomidziyo, asi zviri nani kuchengetedza 2.5mm chikamu chinorambidzwa nzvimbo.

Mazano 4: Kuisa gomba

Tsanangudzo: Mazhinji maitiro akadai sePCB kugadzira, PCB gungano, uye kuyedza zvinoda kumira zvakanaka kwePCB.Naizvozvo, zvinowanzodiwa kugadzira makomba ekumisikidza.

Zvido zvekugadzira:

(1) PaPCB yega yega, maburi maviri ekumisikidza anofanirwa kugadzirwa, imwe idenderedzwa uye imwe yacho yakareba groove chimiro, yekutanga inoshandiswa pakuisa uye iyo yekupedzisira inoshandiswa kutungamira.

Iko hakuna chakakosha chinodiwa kune yekumisikidza aperture, inogona kugadzirwa zvinoenderana neiyo fekitori yako wega.Iyo dhayamita yakakurudzirwa i2.4mm uye 3.0mm.

Makomba ekutsvaga anofanira kunge asina simbi.Kana PCB iri PCB isina chinhu, ndiro yegomba inofanira kugadzirwa kuitira kuisa gomba kuti riwedzere kuoma.

Kureba kwegomba rekutungamirira kunowanzoita 2 nguva dzehupamhi.

Pakati pegomba rekuisa panofanirwa kunge riri kure ne5.0 mm kubva kudivi rekutapurirana, uye maburi maviri ekumisa anofanira kunge ari kure sezvinobvira.Zvinokurudzirwa kuvaisa pane diagonal yePCB.

(2)Kune PCB yakasanganiswa (PCBA ine plug-ins yakaiswa), nzvimbo yemakomba ekumisa inofanira kuenderana.Nenzira iyi, dhizaini yekushandisa inogona kuwana kushandiswa kwakajairwa kwemativi ese ari maviri.Semuenzaniso, screw bottom bracket inogonawo kushandiswa plug-in tray.

Mazano 5: Positioning fiducial

Tsanangudzo: Mouder yemazuva ano, printer, AOI uye SPI zvese zvinotora optical positioning system.Naizvozvo, optical positioning fiducial inofanirwa kugadzirwa paPCB board.

Zvido zvekugadzira:

Positioning fiducial yakakamurwa kuita yepasi rose fiducial uye yemuno fiducial.Iyo yekutanga inoshandiswa kune yese bhodhi chinzvimbo, uye yekupedzisira inoshandiswa pakumisikidza patchwork mwanasikana bhodhi kana yakanaka spacing zvikamu.

(2)Optical positioning fiducial inogona kugadzirwa seskweya, denderedzwa remadhaimani, muchinjiko uye zvakanaka nehupamhi hwe2.0 mm.Kazhinji, zvinokurudzirwa kugadzira 1.0m kutenderera mhangura tsanangudzo nhamba.Iko funga musiyano uripo pakati peruvara rwezvinhu uye nharaunda, isingarambike welding nzvimbo 1 mm yakakura kupfuura iyo optical positioning fiducial inofanira kuchengetwa.Haisi mavara anotenderwa munzvimbo.Kunyangwe paine foil yemhangura mukati memukati pasi pezviratidzo zvitatu pane imwechete board surface inofanira kuenderana.

(3) Pamusoro pePCB pamusoro nezvikamu zveSMD, zvinokurudzirwa kuisa matatu optical positioning fiducial pakona yebhodhi, kuitira kuti uise PCB stereoscopically (mapoinzi matatu anotarisa ndege, inogona kuona kukora kwe solder paste) .

(4) Kuwedzera kune matatu optical positioning fiducial yeplate rese, zviri nani kugadzira maviri kana matatu optical positioning fiducial pamakona ega rega reyuniti ndiro.

(5) Kune QFP ine lead centre chinhambwe chiri pasi kana kuenzana ne 0.5 mm uye BGA ine lead centre chinhambwe chiri pasi kana kuenzana ne 0.8 mm, local optical positioning fiducial inofanira kuiswa pamakona akapesana kuti amire zvakanaka.

(6) Kana paine zvinosungirirwa pamativi ese ari maviri, panofanira kuve neoptical positioning fiducial padivi rega rega.

(7) Kana pasina gomba rekumisa paPCB, pakati peiyo optical positioning fiducial inofanira kunge iri kure ne6.5mm kubva kumucheto wekufambisa kwebhodhi redunhu.Kana paine buri rekumisikidza paPCB, pakati peiyo optical positioning fiducial inofanirwa kugadzirwa padivi pegomba rekumisikidza pedyo nepakati pePCB board.

PCBFuture inogona kupa neTurnkey PCB musanganosevhisi iyo inosanganisira PCB Kugadzirwa, PCB huwandu, Zvikamu zvekutsvaga uye kuyedzwa.Mainjiniya edu anozobatsira mutengi wedu kurongedza mabhodhi pamberi pekugadzirwa kwePCB, uyezve mushure mekupedza bvunzo, isu tichabatsira kupaza chidimbu chimwe nechimwe uye nechikepe kune vatengi vedu.Kana uine chero mibvunzo nezve PCB dhizaini, inzwa wakasununguka kutibata nesu.Tinogona kukupa iwe mahara tekinoroji inotsigira.
