Ngokuqhubela phambili okuqhubekayo kokwakhiwa kwe-5G, iindawo zoshishino ezifana ne-microelectronics echanekileyo kunye ne-aviation kunye ne-Aviation kunye ne-Marine ziye zaphuhliswa ngakumbi, kwaye ezi nkalo zonke zigubungela ukusetyenziswa kweebhodi zeesekethe ze-PCB. Kwangelo xesha linye lophuhliso oluqhubekayo lwale mveliso ye-microelectronics, siya kufumanisa ukuba ukwenziwa kwamacandelo e-elektroniki ngokuthe ngcembe kwenziwa kancinci, kubhityile kwaye kukhaphukhaphu, kwaye iimfuno zokuchaneka ziya zisiba phezulu nangaphezulu, kunye ne-laser welding njengeyona ndlela isetyenziswa kakhulu. iteknoloji kushishino microelectronics, nto leyo ebotshelelwe ukubeka iimfuno eziphezulu neziphezulu kwi-welding degree yeebhodi zesekethe PCB.
Ukuhlolwa emva kokuwelda ibhodi yesekethe PCB kubalulekile kumashishini kunye nabathengi, ngakumbi amashishini amaninzi angqongqo kwiimveliso zombane, ukuba awuyijongi, kulula ukuba nokusilela ekusebenzeni, okuchaphazela ukuthengiswa kwemveliso, kodwa kuchaphazela nomfanekiso wenkampani. kunye nodumo. Izixhobo ze-laser welding eziveliswe yi-Shenzhen Zichen laser zisebenza ngokukhawuleza, isivuno esiphezulu se-welding, kunye nomsebenzi wokubona emva kwe-welding, onokuhlangabezana neemfuno ze-welding processing kunye nokufumanisa emva kwe-welding yamashishini. Ngoko ke, njani ukubona umgangatho PCB ibhodi yesekethe emva ukuwelda? Le ilandelayo Zichen laser yabelana ngeendlela ezininzi ezisetyenziswa ngokuqhelekileyo.
1. PCB indlela yetriangulation
Yintoni unxantathu? Oko kukuthi, indlela esetyenziswayo ukujonga imilo emacala-ntathu. Okwangoku, indlela ye-triangulation iye yaphuhliswa kwaye yenzelwe ukufumanisa umzobo wecandelo lomnqamlezo wesixhobo, kodwa ngenxa yokuba indlela ye-triangulation ivela kwisiganeko esicacileyo sokukhanya kwiindlela ezahlukeneyo, iziphumo zokujonga ziya kuba zihluke. Ngokwenene, into ivavanywa ngomgaqo wokusabalalisa ukukhanya, kwaye le ndlela yeyona ndlela ifanelekileyo kwaye isebenzayo. Ngokubhekiselele kwi-welding surface kufuphi nemeko yesibuko, le ndlela ayifanelekanga, kunzima ukuhlangabezana neemfuno zemveliso.
2. Indlela yokulinganisa ukuhanjiswa kokukhanya kokukhanya
Le ndlela isebenzisa ubukhulu becala inxalenye ye-welding ukuze ibone umhombiso, ukukhanya kwesiganeko sangaphakathi ukusuka kwindlela ethambekele kuyo, ikhamera ye-TV ibekwe ngasentla, kwaye emva koko ukuhlolwa kuqhutywe. Inxalenye ebalulekileyo yale ndlela yokusebenza yindlela yokwazi i-Angle yomphezulu we-solder ye-PCB, ngakumbi indlela yokwazi ulwazi lokukhanyisa, njl., kuyimfuneko ukubamba ulwazi lwe-Angle ngokusebenzisa imibala eyahlukeneyo yokukhanya. Ngokuchasene noko, ukuba kukhanyisiwe ukusuka phezulu, i-Angle elinganisiweyo yindlela yokusabalalisa ukukhanya okubonakalisiweyo, kunye ne-tilted surface ye-solder inokujongwa.
3. Guqula i-engile ukuze ihlolwe ikhamera
Uyibona njani i-PCB emva kwe-welding? Ukusebenzisa le ndlela yokubona umgangatho we-PCB welding, kuyimfuneko ukuba ube nesixhobo esinokutshintsha kwe-Angle. Esi sixhobo ngokuqhelekileyo sineekhamera ze-5 ubuncinane, izixhobo ezininzi zokukhanyisa i-LED, ziya kusebenzisa imifanekiso emininzi, zisebenzisa iimeko ezibonakalayo zokuhlola, kunye nokuthembeka okuphezulu.
4. Indlela yokusetyenziswa ekugxininiseni
Kwezinye iibhodi zeesekethe eziphezulu, emva kwe-PCB welding, iindlela ezintathu ezingentla zinzima ukufumana umphumo wokugqibela, ngoko ke indlela yesine kufuneka isetyenziswe, oko kukuthi, indlela yokukhangela ekugxilwe kuyo. Le ndlela yohlulwe ibe ngamaqela amaninzi, njengendlela yokugxila kwi-multi-segment, ekwazi ukubona ngokuthe ngqo ukuphakama kwe-solder surface, ukufezekisa indlela yokufumanisa ngokuchanekileyo, ngelixa ubeka i-10 i-focus surface detectors, unokufumana indawo ekugxilwe kuyo ngokunyusa. imveliso, ukubona indawo yesolder. Ukuba ichongiwe ngendlela yokukhanya kwe-laser beam encinci kwinto, okoko nje ii-pinholes ezili-10 ezithile zigxadazela kwicala lika-Z, isixhobo esikhokelayo se-0.3mm sinokufunyanwa ngempumelelo.
