Ib tus neeg siv khoom tsim lub twj tso kua mis kho mob tuaj rau peb xyoo tas los nrog ib qho teeb meem: lub voj voog puag ncig lawv tau teev tseg rau lub keypad tau hloov ntawm PCB thaum lub sij hawm ua kom tsis muaj menyuam autoclave. Tom qab tsib lub voj voog, kwv yees li 2% ntawm cov domes tau tig 30 degrees ntawm lub ncoo, thiab kev sib cuag tau sib cuam tshuam. Peb hloov tib lub 6 hli dome, tib lub zog 250g, tib yam khoom SUS301, rau plaub -legged geometry. Kev sib hloov mus rau xoom. Cov neeg siv khoom xav tias peb tau hloov cov khoom siv dome. Peb tsis tau. Peb tsuas yog hloov cov duab xwb.
Geometry ntawm ahlau dome- puag ncig, plaub-legged, lossis hla - hloov pauv nws zaum ntawm PCB, nws tiv taus plua plav li cas, thiab yuav ua li cas nws thiaj li muaj sia nyob ntawm kev poob siab. Feem ntau engineers xaiv txoj kab uas hla thiab quab yuam ua ntej thiab kho geometry raws li lub neej ntawd. Tab sis geometry yog qhov ntsuas uas txiav txim siab seb lub dome nyob twj ywm rau ntawm lub ncoo lossis hloov tom qab siv xyoo.
Hloov, plaub-legged, thiab cross domes staged ntawm ib qho kev sim PCB - txhua qhov geometry sib cuag lub ncoo sib txawv.
Round domes: lub neej ntawd
Ib puag ncig dome yog ib qho yooj yim ncig snap uas tsis muaj ob txhais ceg. Nws zaum ntawm PCB los ntawm zaum ncaj nraim ntawm nws lub npoo, tuav hauv qhov chaw los ntawm daim ntawv dome nplaum saum nws. Kev sib cuag yog tsim los ntawm qhov chaw nruab nrab kov lub PCB ncoo.
Qhov zoo tshaj plaws rau:cov neeg siv khoom siv hluav taws xob uas tsis pom kev vibration lossis thermal cycling. TV chaw taws teeb, teeb- lub thawv sab saum toj, cov keyboards hauv computer. Lub dome puag ncig muab qhov huv tshaj plaws, feem ntau zoo li nyem vim hais tias lub ntug tiv tauj lub ncoo sib npaug txhua txoj kev.
Tsis muaj zog:lub dome tuaj yeem tig los yog hloov ntawm lub ncoo yog tias cov nplaum saum toj no nws poob tack, lossis yog tias cov khoom pom dua thermal shock. Round domes kuj zam cov plua plav tsawg dua li cov domes, vim tias tej plua plav ntawm lub npoo tiv thaiv kev sib cuag.
Plaub-legged domes: lub thauj tog rau nkoj
Ib tug plaub-legged dome muaj plaub lub tab me me uas txuas los ntawm ntug uas zaum ntawm PCB ncoo. Cov tabs ua raws li cov thauj tog rau nkoj, tiv thaiv kev sib hloov thiab lateral txav. Kev sib cuag tseem yog tsim los ntawm qhov chaw nruab nrab, tab sis ob txhais ceg ua kom lub dome nyob rau hauv lub ncoo txawm tias cov nplaum saum toj no tsis ua haujlwm.
Qhov zoo tshaj plaws rau:automotive, industrial, thiab cov khoom kho mob uas pom kev vibration, thermal cycling, lossis sterilization. Plaub -legged geometry yog qhov peb spec rau lub kauj log hloov, cov twj tso kua mis, thiab lub Hoobkas hauv pem teb keypads qhov twg lub dome yuav tsum nyob twj ywm rau 10 xyoo.
Tsis muaj zog:qhov nias yog me ntsis nkig tshaj ib puag ncig dome, vim hais tias ob txhais ceg hloov txoj kev lub dome snaps los ntawm. Lub zog kam rau ua yog me ntsis dav. Ob txhais ceg kuj xav tau ib lub ncoo loj me ntsis, yog li lub hauv paus ncoo yuav tsum muaj tsawg kawg yog 0.5 mm loj dua ib puag ncig dome ncoo.
Plaub -legged domes - ob txhais ceg txuas lub dome ntawm PCB ncoo thiab tiv thaiv kev sib hloov.
Hla domes: hmoov av thiab qaij fighter
Ib tug ntoo khaub lig dome muaj plaub caj npab ncua ntawm qhov chaw es tsis txhob ntawm ib tug nruam rim. Lub caj npab nqa tawm ntawm lub ncoo thaum lub dome snaps, uas txhais tau hais tias plua plav thiab paug ntawm lub ncoo tsis tiv thaiv kev sib cuag. Hla domes kuj zam tawm - nruab nrab nias: yog tias tus neeg siv nias tus yuam sij me ntsis tawm -axis, tus ntoo khaub lig caj npab tseem snaps sib npaug.
Qhov zoo tshaj plaws rau:Cov khoom siv sab nraum zoov, qhov chaw muaj plua plav, thiab cov keyboards uas tus neeg siv hnav hnab looj tes lossis nias tsis raug. Cov cuab yeej siv kev tsim kho, kev tswj kev ua liaj ua teb, thiab cov consoles hauv hiav txwv yog cov ntawv hla -dome. Tus ntoo khaub lig geometry kuj yog qhov kev xaiv raumembrane hloovpanels qhov twg lub overlay yog tuab thiab xovxwm taw tes yog tsis paub tseeb.
Tsis muaj zog:ntoo khaub lig domes muaj lub neej luv dua li puag ncig lossis plaub -legged domes, vim hais tias caj npab flex ntau dua thiab qaug zog sai. Lawv kuj xav tau thaj chaw loj dua thiab qhov siab dua dome profile, uas ntxiv rau pawg- nce siab.

Pad tsim hloov los ntawm geometry
PCB pad layout yuav tsum phim lub dome geometry. Ib puag ncig dome xav tau ib lub voj voog txuas ntxiv. Plaub-legged dome xav tau lub ncoo kom nthuav tawm hauv qab txhua ceg, yog li lub ncoo loj dua. Tus ntoo khaub lig dome xav tau lub ncoo kom nthuav tawm hauv qab txhua caj npab, uas txhais tau hais tias lub ncoo tsis yog lub voj voog yooj yim tab sis plaub-lobed zoo li.
Thaum koj xa peb daim duab rau kev caidome daim ntawv arraylos yogtuag- txiav module, qhia rau peb ib puag ncig cov khoom yuav pom thiab peb yuav pom zoo rau txoj cai geometry. Peb kuj xa cov qauv geometry pub dawb kom koj tuaj yeem hnov qhov txawv ua ntej cog lus rau kev ua haujlwm ntau lawm. Rauneeg siv khoom electronics domes, automotive domes, los yogsilicone khawmcov rooj sib txoos,hu rau Shanyo engineeringrau kev txhawb nqa kev xaiv geometry.
