Uninzi lweenjineli ze-elektroniki bekufanele ukuba zithengise ibhodiintsimbi yokuthambisa, kwaye ngaba i-solder ton inetyhefu?
1.Ingaba inkonkxa ye-solder enentsimbi ye-solder inetyhefu?
Abanye abasebenzisi be-intanethi benza izikhalazo malunga nokuba wasebenzisa itoti ye-solder unyaka wonke kumzi-mveliso we-PCB.Waziva eqala ukungakhululeki, kwaye isisu sakhe sasidumba kancinci.Ngaba yityhefu yelothe?
Enyanisweni, kukwaxhomekeke ekubeni i-solder wire esetyenziselwa ukudibanisa nge-soldering iron yombane ayinalothe okanye ayikho emsebenzini, kwaye i-load yegazi kufuneka ihlolwe rhoqo.Ukuba ayigqithisi umgangatho, akuyi kubakho ngxaki konke konke.Ngaba i-solder yityhefu?
Ngokuqhelekileyo, ukuba ukhuseleko kunye nokuthengwa kwezinto eziluhlaza kwenziwa ngokwemigangatho kazwelonke, i-solder tin ayiyi kubangela umonakalo omkhulu.Ngoku kusetyenziswa iimveliso ezingenalothe.
Ilothe sisiyobisi esiyityhefu.Ukufunxa ngokugqithisileyo ngumzimba womntu kuya kubangela ityhefu yelothe.Ukuthathwa kwedosi ephantsi kunokuchaphazela ubukrelekrele bomntu, inkqubo yemithambo-luvo kunye nenkqubo yokuzala.Ingxubevange yetoti kunye nelothe yeyona solder isetyenziswa ngokuqhelekileyo.Ine-conductivity yensimbi efanelekileyo kunye nenqanaba eliphantsi lokunyibilika.Ke ngoko, sele isetyenziswe kwitekhnoloji ye-welding ixesha elide.Ubutyhefu bayo ikakhulu buvela kwilothe.Umsi welothe oveliswa ngetoti yokusoda unokukhokelela ngokulula kwityhefu yelothe.
Ilothe yesinyithi inokuvelisa iikhompawundi zelothe, zonke ezichazwa njengezinto eziyingozi.Emzimbeni womntu, ilothe iya kuchaphazela inkqubo ye-nervous kunye nezintso.Ityhefu yokusingqongileyo yelothe kwezinye izinto eziphilayo iqinisekisiwe ngokubanzi.Uxinzelelo lwegazi olukhokelela kwi-10 μ G / dL okanye ngaphezulu luya kuvelisa iziphumo ezibuthathaka ze-biochemical.Ukuba ibonakaliswe ixesha elide, ugxininiso lwelothe yegazi luya kudlula i-60 ~ 70 μ G / dl iya kubangela ityhefu ekhokelela ekliniki.
Ilothe kufuneka ibe yityhefu.Ungasathethi ke ngetoti yokusoda inefuthe elincinane emzimbeni.Nditsho neentsimbi eziqhelekileyo ziya kuba netyhefu ukuba zininzi kakhulu.Xa i-soldering tin, kuya kubakho umsi, oqulethe into enobungozi emzimbeni.Xa usebenza, kungcono ukunxiba imaski, kodwa iya kuba nefuthe elithile.Ngokuqinisekileyo, ukuba ungasebenzisa ucingo lwe-solder olungenayo i-load, luya kukhuseleka kakhulu kunezo zinelothe.
2, Ngaba ilothe-free solder inetyhefu?
Izinto ezisetyenziselwa ukudibanisa i-tin nge-iron soldering yombane yi-solder wire.Nangona inxalenye yayo ephambili iyitoti, ikwanazo nezinye iintsimbi.Ikakhulu yohlulwe ibe yilothe kunye ne-lead-free (okt uhlobo lokhuseleko lokusingqongileyo).Ngokungeniswa komgangatho we-EU ROHS, ngakumbi nangakumbi iifektri zePCB zokuwelda zikhetha i-load-free kunye nokusingqongileyo.Ucingo lwe-lead solder nalo lutshintshwa kancinane endaweni yalo, olungahambelaniyo nokusingqongileyo kwaye olungenakuthunyelwa kumazwe angaphandle.Intlama ye-lead yasimahla, intambo yenkcenkce engenalothe kunye netoti engenalothe zezona mveliso ziphambili kwimarike ngoku.
Ukuyibeka ngokulula: itoni yokudambisa esetyenziswa ngokubanzi inetyhefu ngenxa yendawo yayo ephantsi yokunyibilika, iqulethe i-60% ilothe kunye ne-40% yetoti.Uninzi lwetoti ye-soldering kwimarike ayinanto kwaye iqulethe i-rosin, ngoko ke igesi oyithethileyo iqikelelwa ukuba iguquke xa i-rosin kwi-soldering tin inyibilika ngexesha le-welding.Irhasi ejikisiweyo esuka kwirosin nayo inetyhefu encinci.Le gesi inuka kakubi.
Eyona nto iyingozi kwitoti yokuthambisa ngumsi welothe.Nkqu netoti yokusoda engenalothe inomlinganiselo othile welothe.Umda womsi okhokelayo kwi-gbz2-2002 uphantsi kakhulu kwaye unetyhefu, ngoko ke kufuneka ukhuselwe.Ngenxa yomonakalo wenkqubo ye-welding emzimbeni womntu kunye nokusingqongileyo, eYurophu, ukukhuselwa kwabasebenzi be-welding kunye nokukhuselwa kokusingqongileyo kuye kwanyanzeliswa ngendlela yomthetho.I-Welding ngaphandle kwamanyathelo okukhusela akuvumelekanga.Kumgangatho we-ISO14000, kukho amalungiselelo acacileyo kunyango kunye nokukhuselwa kongcoliseko oluveliswe kwiikhonkco zemveliso.
Itoti iqulethe ilothe.Ngaphambili, kwakukho ilothe kwi-solder wire.I-Solder ihlelwa njengesithuba esiyingozi emsebenzini (kwikhathalogu yesizwe yezifo zemisebenzi);Ngoku amashishini ethu ngokubanzi asebenzisa i-lead-free solder wire.Inxalenye ephambili yitin, kwaye iziko loLawulo lweZifo kunye nemilinganiselo yokuthintela i-tin dioxide;Ayikho kwikhathalogu yezifo zemisebenzi yesizwe.
Ngokuqhelekileyo, umsi welothe kwinkqubo engenalothe awuyi kudlula umgangatho, kodwa zikho ezinye iingozi kwitoti yokuthambisa.Ngokomzekelo, i-soldering flux (i-rosin substances) ineengozi ezithile, ezimele zibonwe ngokwemeko ethile.Abasebenzi badla ngokujonga ukuchongwa kunye nodidi lwetoti esasaziweyo, ukuze babhalwe kakuhle kwaye bafune ukuba ishishini lenze ulungiso (banokunika izimvo kwimanyano yabasebenzi yangaphakathi yomzi-mveliso).Ukuba i-tin iqulethe ilothe, kufuneka ibe yingozi kwimpilo yakho.Ngokuhamba kwexesha, ziqokelelana emzimbeni kwaye zibangele umonakalo omkhulu kwi-immune system ye-nervous system.
I-lead free solder wire ihambelana nokusingqongileyo, kodwa i-lead-free solder wire nayo iyingozi kumzimba womntu.Umxholo ophantsi okhokelayo we-lead-free wire solder ayikho i-lead-free.Xa kuthelekiswa nentambo ye-solder enelothe, i-lead-free solder wire inongcoliseko oluncinci kwindalo kunye nomzimba womntu kunocingo lwe-solder olunelothe.Irhasi eyenziwe ngexeshai-solderinginetyhefu, kubandakanywa ioli yerosin, i-zinc chloride kunye neminye imiphunga yegesi.
3, Indlela yokuthintela intsimbi yokuthambisa yombane kunye nocingo lwe-solder ekubeni yityhefu
Okokuqala, iifektri ze-PCB kufuneka zisebenzise i-RoHS tin wire xa zithengiswe ngentsimbi yombane, kwaye zenze umsebenzi olungileyo wokuthintela: umzekelo, nxiba iiglavu, iimaski okanye iimaski zerhasi, nikela ingqalelo ekungeneni komoya emsebenzini, ube nokuphuma kakuhle. inkqubo, ingqalelo ukucoca emva komsebenzi, kwaye usele ubisi nako ukuthintela ubutyhefu ilothe kwitoti yokuthambisa.
1. Ukuphumla ixesha elithile: ngokuqhelekileyo, kufuneka uphumle malunga nemizuzu eyi-15 ngeyure ukuze unciphise ukukhathala, kuba ukuchasana kubi kakhulu xa ukhathele.
2. Tshaya kancinci kwaye usele amanzi amaninzi, anokuphelisa uninzi lwezinto eziyingozi ezifunxa emini.
3. Sela isuphu yembotyi yembotyi okanye amanzi obusi phambi kokuba ulale, nto leyo enokunciphisa umlilo kwaye incede umoya wakho, kunye neembotyi zemung kunye nobusi kunokuphelisa ubuninzi belothe kunye nemitha efunsiweyo.
4. Kuphephe ukusasazeka kwemitha kwaye uzame ukunqanda ukulinda iifowuni eziphathwayo.
5. Ungakhanyisa intsimbi ye-soldering kwaye uzame ukusebenzisa intloko ye-welding ye-PPD.Ngale ndlela, xa ubushushu bufikelelwe, ungasebenzisa ioyile yokuwelda encinci kunye nerosin ukunciphisa ubungozi emzimbeni wakho,
6. Xa ioli yokuthambisa kunye netoti iqhuma, zama ukubrasha isibhakabhaka ngentloko yakho ecaleni, kwaye uzame ukubamba umoya wakho xa ubrasha amanzi.
7. Sebenzisa amanzi amancinci eTianna, sebenzisa utywala obuninzi, kwaye uxube ngakumbi ngotywala okwethutyana.Isiphumo siphantse sifane.
8. Hlamba izandla zakho.
9. Hlamba ngaphambi kokuba ulale.Zama ukulala kwaye uvuke ekuseni ukuze uqinisekise ukulala ngokwaneleyo.Ngethuba nje ulala kakuhle, ukungcola kunokukhutshwa kunye nomzimba wakho.
10. Sebenza ngeemaski.
