Qhov tseem ceeb tsim kev txiav txim siab rau lub davhlau ya nyob twg pwm tsim feem ntau suav nrog cov hauv qab no:
Kev siv cov khoom siv thiab pwm kev sib xyaw ua ke
Kev txuag khoom:Cov khoom yuav tsum tau khaws cia kom ntau li ntau tau thaum lub sij hawm tsim layout. Txij li thaum cov khoom siv strip pitch twb txiav txim siab los ntawm cov khoom lossis cov neeg siv khoom thiab tsis tuaj yeem hloov pauv tau, kev ua kom zoo tuaj yeem txiav txim siab hauv cov khoom siv dav, xws li siv ib zaug - cov khoom ob - kab lossis ob - cov ntaub ntawv ob - cov txheej txheem ntxig rau kev txhim kho cov khoom siv.
Shortening Pwm Length:Thaum lub sij hawm tsim pwm, ntau cov txheej txheem yuav tsum ua kom tiav nyob rau hauv tib kauj ruam kom ntau li ntau tau kom txo tau pwm ntev thiab tshem tawm cumulative yuam kev tshwm sim los ntawm machining raug. Qhov no pab txhim kho stamping ceev thiab seem stability, thiab txo tus nqi ib yam khoom.
Kev kho ntawm Tie Deformation
Hom Tie Deformation:Feem ntau khi deformations nyob rau hauv lub davhlau ya nyob twg pwm muaj xws li khi dabtsi yog khoov, khi twisting, thiab khi serpentine.
Txoj kev hloov kho:Rau leadframe deformation, ntau txoj kev hloov kho tuaj yeem txais yuav, xws li kev hloov kho siab zog (siv lub zog siab rau qhov chaw deformed, los yog tam sim ntawd siv lub zog siab nyob rau hauv qhov kev taw qhia tom qab deformation tshwm sim, los yog siv lub zog hloov kho thaum lub sawb tab tom yuav tawm ntawm qhov tuag los tiv thaiv qhov deformation), kho lub feeder, thiab xyuas thiab kho lub voj voog ntawm tus txiv neej thiab lub kaum sab xis. Tsis tas li ntawd, lub zog muaj zog hauv cheeb tsam, kev hloov kho cov txheej txheem, thiab cov txheej txheem khoov tsim nyog thiab cov qauv tseem yog qhov tseem ceeb.
Kev txiav txim siab tsim tseem ceeb rau IC Terminal Tuag
High Precision Requirements:IC leadframes yog cov khoom siv hlau tseem ceeb hauv cov khoom siv hluav taws xob thiab cov ntaub ntawv xov xwm, thiab lawv cov stamping tuag yuav tsum muaj qhov siab. Tuag tsim yuav tsum tsis tsuas yog xav txog kev tsim thev naus laus zis thev naus laus zis nkaus xwb tab sis kuj tseem muaj cov khoom siv ua haujlwm siab -precision processing.
Cov ntsiab lus tseem ceeb rau Leadframe Stamping Processing:Lub hauv ntej kawg ntawm lub puab qhia pins ntawm lub leadframe yuav tsum siab flatness thiab embossing.
