Guozi ntsiav tshuaj feem ntau xa mus rau khawm shrapnel
Lub khawm shrapnel (tseem hu ua hlau dome, snap dome) yog ua los ntawm ultra-nyias (0.05mm-0.1mm thickness) thiab ultra-thick (feem ntau nyuaj) stainless hlau 301 lossis 304 cov ntaub ntawv.Lub khawm shrapnel yog ib feem tseem ceeb ntawm kev hloov.
Suav lub npe: khawm shrapnel
Kuj tseem hu ua: lauj kaub slices
Khoom siv: Stainless hlau 301 lossis 304
Txoj kab uas hla: 3mm-20mm
Button shrapnel feem ntau yog siv rau hauv cov keyboards membrane, dome contact switches, PCB boards, FPC boards, khoom kho mob thiab lwm yam khoom.Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub pob shrapnel: Lub pob shrapnel ntawm lub pob membrane yog nyob rau ntawm qhov chaw ntawm PCB pawg thawj coj saib (feem ntau nyob rau saum cov ntiv tes golden ntawm lub rooj tsav xwm Circuit Court).Thaum nias, qhov chaw nruab nrab ntawm lub shrapnel yog concave thiab kov lub voj voog ntawm PCB., Yog li tsim lub voj voog, qhov tam sim no dhau mus, thiab tag nrho cov khoom tuaj yeem ua haujlwm ib txwm.
Feem ntau, cov pa khawm shrapnels tau muab faib ua round hlau shrapnel, cross-shaped hlau shrapnel, daim duab peb sab hlau shrapnel, thiab oval hlau shrapnel raws li lawv cov duab sib txawv.Txoj kab uas hla ntawm 3 hli mus rau 20 hli, thiab lub zog ntawm 100g txog 600gf.Raws li kev kho deg electroplating, nws tuaj yeem muab faib ua: kub plating, npib tsib xee plating, nyiaj plating, ci ntsa iab thiab lwm yam.Muaj ob hom electroplating ib leeg thiab ob sab electroplating.
