Thaum tsim cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, cov kua nplaum siv tau siv. Nws yog siv rau mounting hluav taws xob qhov chaw ntawm microcircuits thiab yuav tsum muaj cov tsis tsim nyog rau hluav taws xob thiab thermal kuj.
Nyob rau hauv tsab xov xwm no peb yuav saib qhov muaj pes tsawg leeg thiab kev siv ntawm cov nplaum.
Cov nplaum nplaum yuav tsum muaj qhov tshwj xeeb me me thiab thermal kuj. Tib lub sijhawm, nws cov khoom tiv tauj yuav tsum muaj zog, txhim khu kev qha thiab ruaj khov.
Nws tuaj yeem tsim cov yam ntxwv hluav taws xob ruaj khov ntawm cov nplaum los ntawm kev qhia cov hmoov npib tsib xee rau hauv nws cov muaj pes tsawg leeg. Qee zaum palladium, nyiaj thiab kub yog siv rau cov laj thawj no. Qhov ntau ntawm cov hlau feem ntau nyob rau hauv qhov muaj pes tsawg leeg ntawm cov nplaum, qhov zoo dua qhov tam sim no ntws, tab sis lub zog tiv tauj yuav qis dua.
Cov nplaum nplaum yuav elastic, thiab kev sib txuas yuav muaj zog dua yog tias cov ntaub ntawv polymer tau nkag mus rau hauv nws cov muaj pes tsawg leeg. Lawv lav cov khoom nplaum zoo thiab cov nplaum nplaum tsawg.
Polymer-based nplaum tiv thaiv ICs los ntawm kev poob siab, kev co thiab mus tas likub hloov pauv.
Cov nplaum nplaum "Kontaktol" ua tau raws li txhua qhov kev xav tau niaj hnub no. Nws muaj viscous muaj pes tsawg leeg raws li hluavtaws resins. Conductivity muab cov hmoov nyiaj zoo. Los ntawm kev ntxiv ntau yam cawv kuab tshuaj rau cov nplaum, nws cov viscosity tuaj yeem hloov kho.
Ntau tus neeg paub txog hams ua lawv tus kheej cov kua nplaum. Lawv paub cov kua nplaum thoob ntiaj teb uas tuaj yeem siv los ua cov kua nplaum tiv thaiv, transistors, microcircuits thiab cov dab dej kub.
Tsis muaj qhov zais zais loj hauv qhov no, hauv qab no peb yuav saib yuav ua li cas ua cov kua nplaum hauv tsev.
1. Peb muab ib lub raj me me ntawm superglue ua los ntawm cov neeg ua haujlwm hauv Suav teb. Qhib lub pob ntawv ci los ntawm sab nraud. Peb tsaug zog nyob rau hauv ua ntej npaj graphite, nyob rau hauv ib tug npaum li cas sib npaug zos rau cov kua nplaum. Graphite tuaj yeem polished nrog ib daim ntawv sau ntawv (xov yooj yim). Lub stylus yuav tsum yog mos. Lub resulting sib tov yog kom huv si tov nrog ib tug match, tom qab uas peb kaw lub ntim ntawv ci. Cov nplaum nplaum yog npaj siv.
Yog tias koj tsis muaj kua nplaum super ntawm tes, koj tuaj yeem siv zaponlak rau lub hom phiaj no.
2. Koj tuaj yeem siv graphite pas nrig ntawm AA roj teeb thiab tib lub zaponlak. Graphite hmoov yuav tsum tau tov nrog zaponlak kom txog thaum qaub cream thickens. Cov kua nplaum no zoo heev conductivity. Nws yuav tsum tau muab sau tseg tias tsuas yog cov lem ntawm lub TV remotes yog rov qab los nrog xws li cov kua nplaum hauv tsev.
3. Cov khoom xyaw no suav nrog cov av graphite zoothiab cov ntaub ntawv tooj liab. Txhawm rau txuas cov ntaub ntawv no, siv cov kua nplaum los yog kua roj vanish. Graphite tuaj yeem raug tshem tawm los ntawm xaum xaum los ntawm kev npaj nws. Cov ntaub ntawv tooj liab tau txais los ntawm kev ua ib daim ntawm tooj liab nrog rau cov ntaub ntawv me me. Peb muab ob feem ntawm cov ntaub ntawv tooj liab thiab ib feem ntawm graphite hmoov av. Peb khi qhov sib tov nrog kua nplaum. Yog tias tsis muaj kua nplaum, koj tuaj yeem siv cov kua roj vanish.
4. Ib tug ntau yam compound nrog zoo heev conductivity thiab lub zog. Peb yuav xav tau 15 g ntawm graphite hmoov, 30 g ntawm nplua nyiaj, tib tus nqi ntawm vinyl chloride copolymer thiab 32 g ntawm purified acetone. Cov muaj pes tsawg leeg yog sib tov meej. Khaws cov kua nplaum rau hauv lub khob ntim.
