Qauv lub rooj tsavxwm - dab tsi yog hais tias?!

Ib tug kev loj hlob lub rooj tsavxwm yog ib tug saj zawg zog luam Circuit Court board, ie nto, yeej tsim rau mounting ib tug ntau yam ntawm hluav taws xob Cheebtsam. Nws muaj pua pua ntawm qhov uas los ntawm txoj kev hlau ib daim hlab yog electrically interconnected. Lus xaus chips thiab hluav taws xob Cheebtsam yog muab tso rau hauv lub me me-sized qhov thiab ces cob cog rua ntawm daim liab qab nyob ntawm tej. Nyob rau hauv no series ntawm hu muab tso rau hauv sab saum toj, hauv qab thiab nruab nrab ntawm lub Rooj Tswjhwm Saib, tsim los coj ua ke cov ntsiab lus ntau ntawm qhov Circuit Court mus rau hauv av thiab fais fab mov. Nws yuav tsum tau hais txog tias cov kev loj hlob board tsis tau soldering, flux thiab solder. Nyob rau hauv tas li ntawd, thaum ua hauj lwm nrog nws muaj yog tsis muaj mob overheating Cheebtsam, raws li zoo raws li muaj tsis muaj teeb meem uas muaj ntau hom mounting schemes.

Lub hom ntawm kev loj hlob boards

Tam sim no cov kws txawj muaj peb hom ntawm kev loj hlob boards. Ua ntej, nws yog universal qauv, uas yog nyob rau ntawm qhov chaw tsuas metallized vias. Lawv tom qab tus tsim tawm yuav yuav tsum tau kev cob cog rua siv jumpers. Qhov thib ob hom - ib tug tshwj xeeb board. Thaum cov chaw muaj ob txheej txheem Circuit Court (pre-diluted), thiab cov paths thiab qhov kev cai circuits. Thaum kawg, peb hom hais txog qauv laug cam tsim rau cov pab kiag li lawm. Nyob rau hauv cov ntaub ntawv no, tag nrho saum npoo ntawm lub tuav hwj chim tsheb npav, thiab qhia txog cov kwv yees li qhov chaw rau tej daim.

Qauv board, tau nrog nws tus kheej ob txhais tes

Ua ib tug qhob card, yog tias tsim nyog, nws yog heev yooj yooj yim thiab lub hwj chim ntawm ib tug neeg twg. Cov khoom siv rau nws lub hauv paus yog zoo tshaj plaws haum nefolgirovanny PCB. Kab breadboard li no yuav tsum muaj ntaub ntawv siv ib tug pas ntsuas thiab ib tug ntse Awl. Raws li rau lub qhov, lawv yuav tsum tau ua los ntawm ib tug xyaum ntawm 0.8. Sami conductors yuav ua los ntawm tooj liab hlau, thiab qhov tsim nyog xov tooj cua Cheebtsam yog muab siv solder. Nyob rau hauv cov ntaub ntawv no rau tag nrho cov ntsiab tsis mounted rau sab sab thiab los ntawm cov saum toj kawg nkaus. Nyob rau hauv tas li ntawd, nws yog ib qho tseem ceeb uas cov uas nrhiav tau xov tooj cua qhov chaw bent nyob rau hauv xws li ib tug txoj kev uas lawv tau khiav thaum uas tig mus rau cov kev sib cuag neeg xyuas pib. Lub hauv paus ntawm lub qauv lub rooj tsavxwm yog npaj txhij!

Teeb meem ntawm daim ntawv thov kev loj hlob boards

Developers uas los ntawm virtue ntawm cov kev ua ub tas li uas siv cov prototypes ntawm ntau yam siv hluav taws xob, nco ntsoov tias lawv siv yog txuam, raws li ib tug txoj cai, ib tug xov tooj ntawm cov teeb meem. Qhov ib yog cov feem ntau pom tseeb thiab cov lus dag nyob rau hauv lub fact tias tej kev loj hlob board soldered los ntawm txhais tes. Thiab nyob rau hauv cov ntaub ntawv ntawm ua yuam kev nyob rau hauv lub tswvyim nws yog tsim nyog los solder. Secondly, nws yuav tsum tau hais tias yuav ua rau cov ntawv luam Circuit Court board yog feem ntau tsis muaj txiaj ntsim los ua ib tug tib tsab ntawm ib tug siv hluav taws xob. Peb, yog hais tias tus Circuit Court nyob rau hauv analog ICS tsawg degree ntawm kev koom ua ke yog tau tso cai rau ua nto mounting yam, lub microprocessor-raws li cov khoom ua tau li ntawd yog heev yooj yim. Noj rau hauv tus account tag nrho cov yam, nws yog tsim nyog ua ntej rau kev tsom xam txhua yam ua ntej pib mus ua hauj lwm nrog xws li ib tug ntaus ntawv, raws li ib tug qauv board.
