Ukutshintsha ubuchule 6×6 SMTyenye yezona mveliso ze-elektroniki ezithengiswa kakhulu, ngenxa yosetyenziso olubanzi lwezicelo, iye yathandwa luninzi lwabathengi, nokuba imveliso ilunge kangakanani na njengomntu olungileyo, akukho nto igqibeleleyo, kukho iziphene ezithile kwaye iintsilelo.Kukho iingxaki malunga nale mveliso, kodwa ilungile malunga nokusetyenziswa ngokubanzi kunye nomgangatho.Iingxaki zinokulawulwa kwaye ziphetshwe, njengokusebenzisa nokugcina.Ukusetyenziswa nokugcinwa ngokufanelekileyo kunokwenza ubomi bube bubude.Oku kulandelayo kumalunga ne-tACT switch 6x6 yeengxaki eziqhelekileyo.
Ukutshintsha ubuchule 6×6 SMT iingxaki eziqhelekileyo
Ixabiso eliphezulu lokuchasana: okwangoku, abathengi abaninzi abaqhelananga kakhulu nexabiso lokumelana ne-TACT switch 6 × 6.Ngokuqhelekileyo, ixabiso lokuchasana lokutshintsha kwethu lilawulwa ngaphantsi kwe-30m Ohms, ngoko ukusebenza koqhagamshelwano kunye nobomi bokutshintsha kuhle kakhulu, kodwa ezinye iiswitshi zinexabiso eliphezulu lokuxhathisa emva kokushisa kweziko kunye novavanyo lobomi.Yintoni ifuthe lokuchasa okuphezulu kwi-tACT switch 6x6?Ukuba ukuchasana kuphezulu, indawo yoqhagamshelwano ye-shrapnel kunye ne-PIN ye-PIN yokutshintsha incinci.Indawo encinci yokudibanisa iya kukhokelela ekutshintsheni ukungaqhagamshelani.Xa iswitshi ingaqhagamshelwanga, kuya kuba kubi.
Ke ngoko, kufuneka silumke malunga nokumelana nokutshintsha, i-shrapnel kunye ne-PIN yeemfuno ze-electroplating ziphezulu, ixabiso lokumelana ne-electroplating liya kuba liphantsi.Ukutshintsha kuvavanyo lobomi, umphezulu we-shrapnel uya kunxiba, ukuba i-plating incinci, ukuchasana kuphezulu, ukutshintshwa kubi.
Ezimbini, ukuncamathela: ultra-obhityileyo TACT iswitshi 6 × 6 ngokubanzi eyaziwa ngokuba switsha film obhityileyo, switsha obhityileyo kufuna ifilimu obhityileyo, ukuze kuzuzwe obhityileyo ngokwenene.Kodwa ubuninzi bokusebenza kweqondo lokushisa kwefilimu akulunganga, emva kokuba isithando somlilo siya kuwela i-phenomenon.Ixesha lethu lobuchwephesha lathi ukunamathela, enyanisweni, ifilimu ye-viscosity kunye nokungenisa ifilimu ye-PI ilungile kakhulu, ukunamathela kwayo yi-400 g, ngokuhambelana kakhulu nokutshintsha kokusetyenziswa, ukukhanya okuhlala kwehla kangakanani, ukuba kunzima kakhulu kuya kutshintsha ngokuhambelana nesigxina. , abavelisi abaninzi ukuze kugcinwe iindleko zokukhetha ifilimu ye-PI ephantsi, ukutshintshela kulula kakhulu kwiingxaki zokunamathela, Cebisa wonke umntu ukuba abuze umenzi kakuhle ngaphambi kokuthenga.
Okwesithathu, emva kokuba isithando somlilo asikwazi ukucinezela: i-switch enhle, emva kwamava e-welding backflow ayikwazi ukucinezela, ihlwempu kakhulu.Abathengi abaninzi nabo basabela kule ngxaki, ngoko yintoni unobangela?Ukutshintsha kwepetshi kuhambelana ne-PCB, kwaye i-PIN incamathele kwi-solder paste.Ukuba umngxuma we-mesh yentsimbi mkhulu kancinane, i-solder paste kulula ukugeleza ngaphakathi kwi-switch.Ukuba kukho umzimba wangaphandle ngaphakathi kokutshintsha, ngokuqinisekileyo kuya kuchaphazela ukuhamba kwayo.Eyona iqhelekileyo ayishukumi.Enye imeko kukuba ukusebenza kokutywinwa kokutywina akulunganga, gibela kwiswitshi ngaphakathi, ke ingxaki iza.
Ngoko ke, kucetyiswa ukuba abathengi kufuneka banikele ingqalelo kule ngxaki kwinkqubo yokuvelisa.
Isine, isiciko sivaliwe: kwinkqubo yokuvelisa, kuya kubakho ukuvuza kwesiciko kunye nokutshintsha ukuphendula kwabathengi.Isigqubuthelo sokutshintsha esilungileyo siphuma njani?Okokuqala, kufuneka siqonde isakhiwo sokutshintsha, isigubungelo sokutshintsha sisemva kwekhava, le minyaka yesigidi yenkqubo yokuvelisa rhoqo.
Ukuba uqhelene nayo, uya kufumanisa ukuba i-cover iqiniswe ngamanqaku amane e-riveting kwisiseko.Ngethuba nje iindawo ezine ze-riveting zikhululekile okanye iindawo ze-riveting ziyancipha okanye zikhubazekile emva kokushisa okuphezulu, isigqubuthelo siya kuwa.Qaphela kuphela ezi ngxaki zimbini zilandelayo ukukhusela isiciko, isiseko sokusebenzisa izinto ezichasene nobushushu, amanqaku amabini e-riveting kwi-riveting esisigxina, yenza umsebenzi omhle weengxaki ezimbini ezingentla, le ngxaki ixazululwe ngokugqibeleleyo.
5. Ukuvakalelwa kwesandla: Abathengi abaninzi baye baphendula, kwaye imvakalelo yesandla yeesampuli ezithunyelwe ngabaxhasi abaninzi zihambelana kakhulu, kodwa xa kuziwa kwimveliso yobuninzi, ukuvakalelwa kwesandla kuyahluka.Enyanisweni, le ngxaki ixhaphake kakhulu, sonke siyazi ukuba i-switch feel and force force ilawulwa yi-shrapnel.Sihlala sisithi i-shrapnel ihlulwe ibe yi-phosphorus copper shrapnel kunye ne-stainless steel shrapnel.Okwangoku, abavelisi abaninzi bakhetha i-phosphorus copper shrapnel ukuze kugcinwe iindleko.I-Phosphorus copper shrapnel iyabiza kakhulu, nto leyo ekwasisizathu sokusetyenziswa ngokubanzi.Kodwa i-phosphor copper shrapnel emva kokushisa kwesithando somlilo kuya kuvelisa inguqu, i-shrinkage ibaluleke kakhulu, ngoko ikhokelela ekuvakaleni kwesandla esibi.
Ukusetyenziswa kwe-shrapnel yensimbi engenasici ayiyi kuba nale ngxaki, kodwa ixabiso le-shrapnel yensimbi engenasici liphezulu kakhulu, okubangela ukuba abaninzi abavelisi bakhethe umngcipheko we-phosphorus shrapnel yobhedu, ngoko ekuthengeni i-TACT switch 6 × 6 kufuneka ibuze imibuzo ecacileyo. .
Isithandathu, ucinezelo olukhanyayo aluqhubekiyo: abathengi abaninzi, ekusebenziseni imveliso bahlala befumanisa ukuba iqhosha leqhosha aliphenduli, libe nzima kakhulu ukucofa, imveliso inempendulo esebenzayo.Ngenxa yokuba utshintsho lwethu luvezwe emoyeni, iimveliso ezininzi ezigqityiweyo azitywinwa, kwaye abathengi be-elektroniki badinga ukuchithwa kobushushu.Kwimozulu emanzi, i-shrapnel yokutshintsha kulula ukuba i-oxidized, ukusebenza koqhagamshelwano emva kwe-oxidation ayilungile njengangaphambili, oko kukuthi, kukho ingxaki yokucinezela ukukhanya.
Xa sisusa iswitshi, sifumanisa ukuba kukho indawo encinci emnyama kwi-shrapnel, kwaye le ndawo incinci emnyama yimpembelelo ye-oxidation ye-shrapnel.Ngoko ke, kucetyiswa ukuba iimveliso ze-elektroniki esingazisebenzisiyo ngamaxesha aqhelekileyo kufuneka zibekwe kwindawo eyomileyo, kwaye iindawo ze-elektroniki ezihlawulelwayo kufuneka zifakwe kwi-oxidized.
