Lub breadboard yog lub rooj tsav xwm thoob ntiaj teb luam tawm, uas yog, qhov chaw tshwj xeeb uas tsim los rau kev txuas ntau yam xov tooj cua. Nws muaj ntau pua lub qhov, uas yog hluav taws xob txuas nrog hlau strips. Cov lus xaus ntawm microcircuits thiab xov tooj cua yog muab tso rau hauv cov qhov me me no, thiab tom qab ntawd txuas nrog los ntawm cov khoom ntawm cov xov hlau stripped. Nyob rau tib lub sijhawm, cov kab sib txuas nyob rau sab saum toj, hauv qab thiab hauv nruab nrab ntawm lub rooj tsavxwm yog tsim los txuas rau ntau lub ntsiab lus ntawm lub voj voog nrog hauv av thiab lub zog. Nws yuav tsum tau muab sau tseg tshwj xeeb tshaj yog hais tias lub breadboard tsis xav tau ib tug soldering hlau, flux thiab solder. Tsis tas li ntawd, thaum ua hauj lwm nrog nws, tsis muaj kev pheej hmoo ntawm overheating ntawm ib feem, thiab kuj tsis muaj teeb meem nrog rov qab installation ntawm circuits.
Nyob ntawm breadboards
Tam sim no, cov kws tshaj lij paub qhov txawv ntawm peb hom kev tsim qauv tsim. Ua ntej, cov no yog cov qauv thoob ntiaj teb, ntawm qhov chaw uas tsuas muaj
plated qhov. Tom qab ntawd, tus tsim tawm yuav tau txuas lawv sivdhia. Qhov thib ob yog tshwj xeeb boards. Ntawm cov chaw zoo li no muaj ob qho tib si cov saw hlau (pre-wired) thiab lem thiab qhov tsim los rau cov saw hlau uas tsis yog qauv. Thiab thaum kawg, hom thib peb yog cov ntawv luam tawm uas tsim los rau cov khoom siv digital. Nyob rau hauv cov ntaub ntawv no, lub hwj chim rails yog kos nyob rau hauv tag nrho cov nto, raws li zoo raws li cov chaw npaj rau microcircuits.
DIY Breadboard
Kev ua lub rooj tsavxwm hauv tsev yog tias tsim nyog yog qhov yooj yim heev thiab leej twg tuaj yeem ua tau. Raws li cov khoom siv rau nws lub hauv paus, non-foil textolite yog qhov zoo tshaj plaws. Nyob rau hauv cov ntaub ntawv no, cov kab ntawm breadboard yuav siv tau siv ib tug pas nrig thiab ib tug ntse awl. Raws li rau lub qhov, lawv tuaj yeem ua tau siv lub laum 0, 8. Cov conductors lawv tus kheej tuaj yeem ua los ntawm tooj liab hlau, thiab cov khoom siv xov tooj cua tsim nyog tau teeb tsa los ntawm kev sib txuas. Hauv qhov no, tag nrho cov ntsiab lus tsis txuas los ntawm sab hauv qab, tab sis los ntawm sab saum toj. Tsis tas li ntawd, nws tseem ceeb heev uas cov lus xaus
xov tooj cua Cheebtsam tau khoov kom lawv khiav mus rau qhov sib txuas mus rau tus neeg xyuas pib. Breadboard puag npaj!
Breadboard Application Problems
Cov neeg tsim khoom uas, los ntawm kev tsim txiaj ntawm lawv cov haujlwm, tas li siv cov qauv ntawm ntau yam khoom siv hluav taws xob, nco ntsoov tias lawv siv feem ntau cuam tshuam nrog ntau yam teeb meem. Thawj ntawm cov no yog qhov pom tseeb tshaj plaws thiab cov lus dag nyob rau hauv qhov tseeb tias txhua lub rooj tsav xwm prototyping yog soldered los ntawm tes. Thiab yog hais tias muaj ib qho yuam kev nyob rau hauv lub Circuit Court, nws yuav tsum tau re-soldered. Qhov thib ob, nws yuav tsum tau hais tias txhawm rau tsim ib qho qauv ntawm ib qho khoom siv hluav taws xob, nws yog qhov yooj yim heev uas tsis muaj txiaj ntsig los ua lub rooj tsav xwm luam tawm. Thirdly, yog hais tias circuits ntawm analog microcircuits ntawm ib tug tsawg degree ntawm kev koom ua ke raug tso cai nqa tawm los ntawm ib tug hinged mounting txoj kev, ces microprocessor khoom yog heev nyuaj ua li ntawd. Xav txog txhua yam no, nws yuav tsum tau txheeb xyuas txhua yam ua ntej ua ntej pib ua haujlwm nrog cov cuab yeej xws li lub khob cij.
