Lead Frame Material Strips

Daim ntawv thov ntawmtooj liab ntawv cinyob rau hauv cov hlau lead yog feem ntau yog reflected nyob rau hauv cov nram qab no yam:

● Cov khoom xaiv:
Lead thav duab feem ntau yog ua los ntawm tooj liab alloys los yog tooj liab cov ntaub ntawv vim tooj liab muaj hluav taws xob conductivity thiab siab thermal conductivity, uas muaj peev xwm xyuas kom meej cov teeb liab kis tau tus mob thiab zoo thermal tswj.

● Cov txheej txheem tsim khoom:
Etching: Thaum ua cov hlau lead, cov txheej txheem etching yog siv. Ua ntej, txheej txheej ntawm photoresist yog coated rau ntawm lub phaj hlau, thiab tom qab ntawd nws raug rau cov etchant kom tshem tawm qhov chaw uas tsis tau npog los ntawm photoresist los ua ib qho zoo txhuas thav duab qauv.

Stamping: Ib qho kev tuag zuj zus yog ntsia rau ntawm cov xovxwm kub ceev los tsim cov hlau lead los ntawm cov txheej txheem stamping.

● Kev ua tau zoo:
Lead thav duab yuav tsum muaj hluav taws xob zoo, siab thermal conductivity, txaus lub zog thiab toughness, zoo formability, zoo heev vuam kev ua tau zoo thiab corrosion kuj.
Copper alloys tuaj yeem ua tau raws li qhov yuav tsum tau ua. Lawv lub zog, hardness thiab toughness tuaj yeem hloov kho los ntawm alloying. Nyob rau tib lub sijhawm, lawv yooj yim los ua cov txheej txheem nyuaj thiab meej cov qauv txhuas los ntawm precision stamping, electroplating, etching thiab lwm yam txheej txheem.

● Environmental adaptability:
Nrog rau cov kev cai ntawm ib puag ncig cov kev cai, tooj liab alloys ua tau raws li cov kev lag luam ntsuab xws li txhuas-dawb thiab halogen-dawb, thiab yooj yim rau kev ua tau zoo ib puag ncig.
Nyob rau hauv cov ntsiab lus, daim ntawv thov ntawm tooj liab ntawv ci nyob rau hauv cov hlau lead thav duab yog feem ntau yog reflected nyob rau hauv cov kev xaiv ntawm cov ntaub ntawv tseem ceeb thiab cov kev cai nruj rau kev ua tau zoo nyob rau hauv cov txheej txheem tsim, thaum coj mus rau hauv tus account ib puag ncig tiv thaiv thiab sustainability.
