Yepamusoro-mhando PCB zvikamu (PCBA) zvave chinhu chikuru chinodiwa muindasitiri yemagetsi. PCB Assembly inoshanda sechinhu chakabatanidzwa kune zvakasiyana-siyana zvemagetsi. Kana mugadziri wePCB akatadza kuita oparesheni nekuda kwechikanganiso chekugadzira, mashandiro emhando dzakasiyana dzemagetsi anotyisidzirwa. Kuti udzivise njodzi, PCBS nevagadziri vegungano vava kuita mhando dzakasiyana dzekuongorora paPCBas pamatanho akasiyana ekugadzira. Iyo blog inokurukura akasiyana PCBA maitiro ekuongorora uye mhando dzehurema dzavanoongorora.

PCBA check method

Nhasi, nekuda kwekuwedzera kuoma kwemabhodhi edunhu akadhindwa, kuzivikanwa kwezvakaremara zvekugadzira kunonetsa. Nguva zhinji, PCBS inogona kuve nehurema senge akavhurika uye mapfupi maseketi, mafambiro asiri iwo, ma welds asingaenderane, zvisizvo zvisizvo, zvakaiswa zvisizvo zvisizvo, zvakaremara zvisiri zvemagetsi, zvisipo zvemagetsi, nezvimwe. Kuti udzivise aya ese mamiriro, turnkey pcb gungano vagadziri vanoshandisa zvinotevera nzira dzekuongorora.

All of the techniques discussed above ensure an accurate inspection of electronic PCB components and help ensure the quality of PCB components before they leave the factory. Kana uri kufunga PCB gungano kuti rinotevera purojekiti, iva nechokwadi kuwana zviwanikwa kubva akavimbika PCB gungano masevhisi.

Hunhu hwekugadzira hunogara hunoenderana nekushanda kwakakodzera kweSMT. Naizvozvo, vasati vatanga kuungana uye kugadzira, vagadziri vePCB vanoita ongororo-yekutanga kuona kuti michina yeSMT yakaiswa zvakanaka. Ongororo iyi inovabatsira kuona vacuum nozzles uye matambudziko ekumisikidza anogona kudzivirirwa mukugadzirwa kwevhoriyamu.

Kuongorora kunoonekwa kana kuvhurika – kutarisa kweziso ndeimwe yemaitiro anonyanya kushandiswa ekuongorora panguva yegungano rePBB. Sezvinoratidzwa nezita racho, izvi zvinosanganisira kuongorora zvikamu zvakasiyana-siyana kuburikidza neziso kana detector. Kusarudzwa kwemidziyo kuchaenderana nenzvimbo ichaongororwa.Semuenzaniso, kuiswa kwezvikamu uye kudhindwa kwe solder paste kunoonekwa kune ziso rakashama. Nekudaro, madhipoziti ekuisa uye mapedhi emhangura anogona kungoonekwa neZ-yepamusoro detector. Mhando yakajairika yekuongororwa kwechitarisiko inoitwa pane reflow weld yeprism, uko mwenje unoratidzwa unoongororwa kubva kumakona akasiyana.

Otomatiki optical kuongorora

AOI ndiyo yakajairika asi yakazara maitiro ekuongorora maitiro anoshandiswa kuratidza hurema. AOI inowanzoitwa pachishandiswa makamera mazhinji, mwenje masosi, uye raibhurari yemadhizaini akatungamirwa. AOI masisitimu anogona zvakare kudzvanya mifananidzo yemajoini anotengeswa pamakona akasiyana uye zvikamu zvakarereka. Many AOI systems can check 30 to 50 joints a second, which helps minimize the time needed to identify and correct defects. Nhasi, masisitimu aya anoshandiswa mumatanho ese ekusangana kwePCB. Pakutanga, maAOI masystem anga asingatariswe seakakodzera kuyera solder yekubatana pakakwirira paPCB. Zvakadaro, nekuuya kwe3D AOI masisitimu, izvi zvave kugona. Pamusoro pezvo, masisitimu eAOI akanakira kuongorora maumbirwo akaomarara ane spacing ye0.5mm.

X-ray kuongororwa

Nekuda kwekushandiswa kwavo mumidziyo midiki, kudiwa kwedenser uye compact saizi yedunhu redunhu bhodhi zvikamu zviri kukura. Surface mount tekinoroji (SMT) yave sarudzo yakakurumbira pakati pevagadziri vePCB vari kutsvaga kugadzira yakaomesesa uye yakaoma PCBS vachishandisa BGA yakarongedza zvinhu. Kunyangwe SMT ichibatsira kudzikisa saizi yePCB mapakeji, inosumawo kumwe kuomarara kusingaonekwe neziso rakashama. Semuenzaniso, diki chip package (CSP) yakagadzirwa neSMT inogona kunge iine 15,000 welded zvinongedzo izvo zvisiri nyore kusimbiswa nemeso. Apa ndipo panoshandiswa maX-ray. It has the ability to penetrate solder joints and identify missing balls, solder positions, misalignments, etc. Iyo X-ray inopinda mu chip package, iyo ine chinongedzo pakati peyakasimba yakabatana redunhu bhodhi uye solder joint pazasi.

Ese matekiniki akurukurwa pamusoro anovimbisa kuongororwa kwakaringana kwezvinhu zvemagetsi uye kubatsira PCB vanounganidza kuti vaone kunaka kwavo vasati vasiya chirimwa. Kana iwe uri kufunga nezvePCB zvinoumba zveako rinotevera chirongwa, ita shuwa kuti utenge kubva kune anovimbwa pcbbbbmugadziri.
