Txhawm rau kom muaj lub suab txuas ntxiv rau suab hauv tsev lossis hauv tsheb, nws tsis tas yuav yuav nws hauv khw. Ua rau nws tsis yog qhov nyuaj txhua. Txhawm rau ua qhov no, koj yuav tsum muaj kev paub me ntsis ntawm kev siv hluav taws xob thiab kev xav me me.
Nws yog qhov tsim nyog
aluminium ntawv, square, sawb, TDA 7294 microcircuit
Cov Lus Qhia
Kauj ruam 1
Nqa 15 x 15 hli txhuas lub xwmfab, koj yuav xav tau nws los ua rooj plaub. Txiav tawm cov xuav. Ua racks ncaj. Tag nrho cov tuab ntawm cov amplifier yuav yog 60 hli, lub khob npog yuav tuab 4 hli, hauv qab yuav yog 1.5 hli, thiab qhov siab qhov siab yuav tsum yog 51,5 hli.
Kauj ruam 2
Ua kab rov tav cov ntsiab. Txhawm rau muab qhov chaw ntsaws rau kom xis, txiav txhua qhov kawg ntawm cov plaub fab ntawm kaum ntawm 45 degrees. Txhawm rau rooj sib hais nrog qhov ntev 430X250X60, koj yuav xav tau yim plaub fab - 4 daim ntev 422 hli, thiab 4 daim ntev 250 hli.
Kauj ruam 3
Daws lub thav duab. Qhov no yuav tsum tau ua cov siv M3 screws, uas yuav yooj yim heev hauv qhov no. Sau ob lub voos xwm fab ib qho rau sawv ntsug. Tom ntej no, ua cov ntsa hauv qab thiab rov qab. Txhawm rau ua qhov no, siv daim ntawv txhuas 1.5 hli tuab tuab. Txiav nrog qhov taub. Thaum koj txiav, ua kom nws muaj millimeter loj dua kom haum cov ntug sib hloov tau yooj yim dua. Rhais cov tiav hauv qab mus rau tus ncej nrog screws.
Kauj ruam 4
Ua nraub qaum ntawm qhov rooj hauv tib txoj kev. Sab nraub qaum ntawm rooj plaub, nruab lub zog txuas, cov tswv yim thiab cov tsho loj, uas zoo tshaj plaws yuav khoom ua ntej. Tom qab ntawd tho qhov nyob rau sab nraum qab phab ntsa. Ua ob txhais ceg rau lub suab nrov, koj tuaj yeem coj lawv npaj-ua los ntawm lub ris tsho qub.
Kauj ruam 5
Ua rau pem hauv ntej vaj huam sib luag. Txhawm rau ua qhov no, siv kab xev tuab 5 hli tuab. Rau rooj plaub, koj yuav tsum tau ua bar uas yuav zais qhov mechanism. Yog tias xav tau, lub cev tuaj yeem pleev xim nrog cov xim pleev xim.
Kauj ruam 6
Ua lub pob hloov hloov hauv txoj kev hauv qab no: luam tawm cov duab ntawm lub neej yav tom ntej ntawm lub tshuab luam ntawv laser ntawm qhov ntsuas kub 1: 1. Tom qab ntawd daim duab yuav tsum tau txiav thiab muab tso nrog cov duab cia rau ntawm qhov ua kom xeb ntawm fiberglass yav dhau los. Tom qab ntawd hloov nws mus rau ntawv ci, ironing nws nrog kub hlau. Nws qhov kub yuav tsum yog nyob ntawm nws qhov siab tshaj plaws. Hlau kom huv si rau 2-3 feeb thiab cia lub board kom txias. Lub toner yuav yaj thiab khi rau ntawm ntawv ci, tom qab ntawd tshem daim ntawv hauv dej sov. Qhov tshwm sim yog qhov kev tshaj lij zoo luam tawm Circuit Board.
Kauj Ruam 7
Ua ib pawg tswj hwm rau lub capacitors los ntawm kev kos nrog tus cwj mem kos duab. Ua li no, siv cov koob txhaj zoo tib yam nrog rab koob tsis meej. Ncuav nitro varnish rau hauv nws lub cev thiab kos paths nrog nws. Etch ob lub log hauv ferric chloride tov thiab sau.
Kauj ruam 8
Cais tawm TDA7294 microcircuit los ntawm lub tshuab hluav taws xob, yog li nws muaj qhov tsis zoo ntawm nws rooj plaub. Qhov no tuaj yeem ua tiav siv cov ntsuas kub-tshwj xeeb ua cua sov, uas yuav tsum me ntsis loj dua li qhov tsuas yog qhov microcircuit lossis mica. Insulate lub hau ntswj ntsia hlau nrog lub tes tsho uas tsis muaj qhov coj ua. Ntxig cov laug cam hauv rooj plaub.
Kauj Ruam 9
Nqa cov tshuab ua kom nrov zog txuas pob qhov rooj rau sab xub ntiag. Tuav lub hau npog sab saum toj.
