Ukusetyenziswa koHlolo lwe-X-Ray kuLawulo loMgangatho we-PCBA oluQhelekileyo: Ukutyhila iziphene zangaphakathi
Kwindawo ye ibhodi yesekethe eprintiweyo rhoqo (PCB) ukuvelisa, ukuqinisekisa ukuba umgangatho wemveliso ubaluleke kakhulu. Itekhnoloji yokuhlola i-X-ray ivele njengesixhobo esibalulekileyo sokufumanisa iziphene zangaphakathi ezingabonakaliyo, ibonelela ngendlela engonakalisiyo yokuvavanya nokuqinisekisa ukuthembeka kwe-PCBA. Kwiinjineli zolawulo lomgangatho, ukuba nobuchule kule teknoloji kubalulekile ukugcina imigangatho ye-PCBA esetyenziswa rhoqo.
Ukuqonda iMigaqo yoHlolo lwe-X-Ray
Ukuhlolwa kwe-X-reyi kusebenza ngokomgaqo wokufunxwa komahluko, apho izinto ezahlukeneyo zifunxwa ii-X-reyi ukuya kumanqanaba ahlukeneyo ngokusekwe kubuninzi bazo kunye nenani le-athomu. Njengoko ii-X-reyi zingena kwi-PCBA ephindaphindayo, izinto ezifana nemikhondo yobhedu, ii-substrates, amalungu e-solder, kunye nezizalisi zangaphakathi zibonisa iimpawu zokufunxwa ezikhethekileyo. Izinto ezixineneyo ezifana nobhedu zifunxwa ii-X-reyi ezininzi, zibonakala zimnyama kwimifanekiso ephumayo, ngelixa izinto ezingaxineneyo kangako zibonakala zikhaphukhaphu. Ngokuhlalutya ezi mahluko, iinjineli zinokuchonga izinto ezingaqhelekanga zangaphakathi. Umzekelo, umkhondo wobhedu oqhubekayo kufuneka ubonakale njengomgca omnyama ohambelanayo; naluphi na ukuphazamiseka okanye ukungahambelani kunokubonisa isiphene. Le ndlela yokufota inika indlela ecacileyo nesebenzayo yokuhlola ulwakhiwo lwangaphakathi lwe-PCBA.
Izinto Ezibalulekileyo Eziqwalaselweyo Ukuze Uhlolwe Nge-X-Ray Ngokusebenzayo
Ukuphucula iiParamitha zeZixhobo
Ukuchaneka kokuhlolwa kwe-X-ray kuchaphazeleka kakhulu ziisethingi zezixhobo, ingakumbi i-voltage yetyhubhu kunye nomsinga. Kwi-PCBA ephindaphindayo, ezi parameters kufuneka zilungelelaniswe nobukhulu bebhodi kunye nokwakheka kwezinto. Ukuhlola i-PCBA etyebileyo, enezilayi ezininzi kudla ngokufuna i-voltage ephezulu yetyhubhu (ukusuka kwi-100 ukuya kwi-160kV) ukuqinisekisa ukungena ngokwaneleyo. Umsinga wetyhubhu uchaphazela ubunzulu be-X-ray; ukukhetha umsinga ofanelekileyo (oqhelekileyo phakathi kwe-2 ukuya kwi-5mA) kuqinisekisa imifanekiso enokuchasana nokucaca okwaneleyo. Ixesha lokuvezwa yenye into ebalulekileyo; zombini ukuvela kakhulu kunye nokungaveli ngokwaneleyo kunokonakalisa umgangatho womfanekiso. Ngokusebenzisa uvavanyo namava, iinjineli zinokumisela amaxesha okuvezwa afanelekileyo kwiintlobo ezahlukeneyo ze-PCBA, ngokubanzi ukusuka kwimizuzwana embalwa ukuya kwimizuzwana emininzi.
Ukufunyanwa koMfanekiso kunye noHlahlelo
Izixhobo zokubona ezinesisombululo esiphezulu zibalulekile ekubambeni imifanekiso eneenkcukacha zezakhiwo zangaphakathi ze-PCB, nto leyo evumela ukufunyanwa kweziphene ezincinci. Iinkqubo zokuhlola ze-X-ray zanamhlanje zibonelela ngezisombululo ezifikelela kwii-microns ezimbalwa, zityhila iinkcukacha ezintsonkothileyo zeempawu zangaphakathi. Nje ukuba imifanekiso ifunyenwe, isoftware ekhethekileyo inceda iinjineli ekuyicubunguleni nasekuyihlalutyeni. Iimpawu ezinje ngokuphucula umfanekiso, ukufunyanwa komphetho, kunye nokuqatshelwa kweziphene zenza kube lula ukuchongwa kweengxaki ezifana nokungahambelani komkhondo okanye ukungaqheleki kwamalungu e-solder. Umzekelo, ii-algorithms zokuphucula umfanekiso zinokuphucula umahluko, zenze iziphene ezincinci zibonakale ngakumbi; iindlela zokuchonga umphetho zichaza imida yeempawu kunye namalungu e-solder, zinceda ekufumaneni iziphene okanye ukuguguleka; kwaye ukuqatshelwa kweziphene ngokuzenzekelayo kunokuqaqambisa iindawo ezixhalabisayo, kwenze inkqubo yokuhlola ibe lula.
Ukuchonga Iziphene: Iimpawu, Izizathu, kunye nexabiso lokuhlolwa kwe-X-Ray
Iziphene zoMkhondo wangaphakathi
1.Iimpawu: Iziphene zangaphakathi zemikhondo zingabonakala njengeziphazamiso, iishothi, okanye ukubola. Iziphazamiso zibonakala njengeziphazamiso kwimigca eqhubekekayo, iishothi njengeminxibelelwano engalindelekanga phakathi kwemikhondo, kunye nokubola njengeendawo apho imikhondo inciphile okanye inciphile.
