Ukukhiqizwa kwe-PCB ne-PCBA esezingeni eliphezulu | INJABULO EGCWELE ECEBILE ngokuhlolwa kwe-X-RAY

Endleleni eguqukayo ye-SMT (Surface Mount Technology), ikhwalithi ye-PCBA (Printed Circuit Board Assembly) ibe yitshe lesisekelo kubakhiqizi be-SMT ukuthi bavelele emakethe. Kusukela esigabeni sokuqala se-Pcb Prototype, ukuhlela ngokucophelela ukwakheka kwe-Pcb kanye nokwakheka kwayo, kuya enkambisweni eqinile ye-Pcb Assembly And Testing, isinyathelo ngasinye sibalulekile kwikhwalithi yomkhiqizo. I-RICH FULL JOY, ngokubambisana ne-Unico Inspection, iveza i-AX7900 Micro-focus X-RAY Fluoroscopy Inspection Equipment. Ngamandla obuchwepheshe angenakuqhathaniswa kanye nomklamo ohlakaniphile, isebenza njengomqaphi wokugcina wekhwalithi ye-PCBA, iqinisekisa ukuthi yonke ibhodi yesifunda ikhanya ngokuphelela okungenaphutha.​

I-AX7900 Micro-focus X-RAY Fluoroscopy Inspection Equipment iyisibonakaliso esibonakalayo sokuphishekela kwe-RICH FULL JOY ikhwalithi. Ihlanganisa ingqikithi yezinkambu ezine zobuchwepheshe eziyinhloko: i-optics, i-mechanics, i-electronics, kanye nokucutshungulwa kwezithombe zedijithali. Ingxenye eyinhloko, umthombo we-X-ray ogxile kakhulu, yenziwe ngobuchwepheshe obusezingeni eliphezulu. Lo msebe we-X-ray ogxile kakhulu ufana nokubuka okungenakunyakaziswa kwe-RICH FULL JOY okubheke phambili. Ngokusebenzisa umehluko ekumuncweni kwe-X-ray ngezinto ezahlukahlukene, ingena ebusweni bamabhodi wesekethe we-PCBA futhi igxile ezakhiweni zawo zangaphakathi eziyinkimbinkimbi. Kungakhathaliseki ukuthi kungamakhona afihliwe amabhodi wesekethe anezingqimba eziningi noma ukwakheka kwangaphakathi kwamadivayisi apakishiwe, yonke imininingwane yemizuzu ivezwa ngokucacile ezithombeni zokuhlola, kungashiyi ndawo yeziphambeko ezingaba khona.​

I-flat panel detector enencazelo ephezulu ehlanganiswe kudivayisi imele "njengeso legolide" lokuhlola ikhwalithi, umsebenzi wobuciko owenziwe yi-RICH FULL JOY. Inezindawo eziningi zokuthatha izithombe ezisebenzayo ezingama-130×130mm, isebenza njengekhanvasi ebanzi yokuqinisekisa ikhwalithi, ibamba ngokucophelela yonke imininingwane ye-PCBA ngokunemba okungenakuqhathaniswa. I-matrix yayo yamaphikseli angu-1536×1536, ehlanganiswe nosayizi wamaphikseli amancane angama-micron angu-85, inikeza izinga elimangalisayo lokucaca kwesithombe, okuvumela ukutholakala kwamaphutha amancane njengengxenye eyodwa kweziyishumi yobubanzi bezinwele zomuntu.

Ngesilinganiso sohlaka samafreyimu angu-20 ngomzuzwana, iqinisekisa ukubonakala okungenamthungo nesikhathi sangempela kwezithombe zokuhlola, ihlinzeka opharetha ngolwazi olusheshayo nolunembile. Umsebenzi wokuthambekela kwe-±30°, ohambisana nobubanzi bokunyakaza obungu-300mm, uvumela ukuhlolwa okuphelele, kwamadigri angu-360 kwe-PCBA kuzo zonke izinhlangothi nezindawo ezingacatshangwa. Lokhu kuqinisekisa ukuthi azikho izinto ezibeka engcupheni ikhwalithi, kungakhathaliseki ukuthi zincane noma zifihliwe kangakanani, ezingagwema ukuhlolwa kwayo, zivikele ubuqotho kanye nobuhle bayo yonke i-PCBA ekhiqizwayo.

Ezimweni zokusetshenziswa okusebenzayo, i-AX7900 ikhombisa ikhono eliyingqayizivele le-RICH FULL JOY lokulawula ikhwalithi. Ezinkingeni ezifana nokusongelwa okubandayo kwejoyinti le-solder, ingakhomba ngokunembile izikhala ezincane, ezincane njenge-micrometer eminingana, phakathi kwamalunga e-solder nama-pad. Uma ibhekene nezingozi zesekethe esifushane, idivayisi ingangena ungqimba lokufakelwa kwebhodi lesekethe futhi inqume ngokucacile ukuthi kukhona ukuxhumana kukagesi okungajwayelekile phakathi kwamasekethe. Izingozi ezifihliwe ezifana namabhamuza kanye nemifantu ngaphakathi kwezingxenye nazo zivezwa ngokugcwele ngaphansi kokuhlolwa kwe-AX7900. Umsebenzi wayo oyingqayizivele wokulinganisa ungabala ngokunembile ivolumu kanye nendawo yamabhamuza emikhiqizweni ye-elekthronikhi/ye-semiconductor, nge-margin yephutha elawulwa ngaphakathi kwe-1%. Umsebenzi wokuhlela isikhundla uvumela abasebenzisi ukuthi basethe kalula amaphuzu amaningi okuhlola, okuvumela ukuhlolwa kwamaphuzu amaningi. Kungakhathaliseki ukuthi amaphakheji e-BGA (Ball Grid Array) ayinkimbinkimbi noma amadivayisi e-QFP (Quad Flat Package) anabantu abaningi, ingaqeda ukuhlolwa ngokushesha nangokunembile. Umsebenzi wokuzulazula okuzenzakalelayo, ohlanganiswe nokusetha isithombe okuzenzakalelayo okuqopha ulwazi lwephuzu lesici, kuvumela opharetha ukuthi basebenzise izinkinobho ezimbalwa nje, futhi idivayisi ingathola ngokushesha indawo yokuhlola ekhethiwe futhi ithole ngokuzenzakalelayo idatha yokuhlola yomlando ukuze ihlaziywe ngokuqhathanisa, okuthuthukisa kakhulu ukusebenza kahle kokuhlola nokunemba nokwakha umugqa wokuzivikela oqinile wokulawula ikhwalithi.

Thatha inkampani ye-elekthronikhi eyaziwayo njengesibonelo. Ngaphambi kokubambisana ne-RICH FULL JOY nokwethula i-AX7900, izinga lokungasebenzi kahle komugqa wayo wokukhiqiza we-PCBA ngenxa yeziphambeko ezifihliwe laliphezulu ngamaphesenti angu-3, ​​okwaholela ekulahlekelweni komnotho kwaminyaka yonke okungaphezu kwezigidi eziyishumi zama-yuan ngenxa yezinkinga zekhwalithi yomkhiqizo. Kodwa-ke, ngemuva kokusebenzisa ukuhlolwa kwenqubo ephelele ne-AX7900, izinga lokungasebenzi kahle lehle laya ngaphansi kuka-0.1%, kanti izinga lokubuyiselwa kwemikhiqizo emakethe lalicishe libe yi-zero. Le mpumelelo emangalisayo ayigcinanga nje ngokusindisa inkampani inani elikhulu lezindleko kodwa futhi yasiza imikhiqizo yayo ukusungula idumela elihle kakhulu emakethe, ukwaneliseka kwamakhasimende kukhuphuka kancane kancane.​

I-RICH FULL JOY ibilokhu ikholelwa ngokuqinile ukuthi ikhwalithi iyisisekelo sentuthuko yebhizinisi. Zonke izici ze-AX7900 Micro-focus X-RAY Fluoroscopy Inspection Equipment, kusukela ocwaningweni nasekuthuthukisweni kuya ekukhiqizeni, ziye zabhekana nokulawulwa kwekhwalithi okuqinile kanye nokuhlolwa kokusebenza yi-RICH FULL JOY. Akuyona nje ingxenye yemishini yokuhlola; ukuzibophezela okungapheli kwe-RICH FULL JOY ekuvikeleni ikhwalithi ye-PCBA. Ukukhetha i-RICH FULL JOY kanye ne-AX7900 kusho ukukhetha isiqinisekiso sokugcina sekhwalithi, okwenza wonke amabhodi wesekethe we-PCBA akhanye emakethe ngekhwalithi engenaphutha futhi awine ukwethenjwa.
