Kev sib xyaw ua ke microcircuit, nyob rau hauv uas tag nrho cov ntsiab lus ua rau ntawm ib qho khoom siv lead ua, tsis tuaj yeem ua nws tus kheej. Tsuas yog qhov thiaj li sib xyaw phiaj xwm tswv yim ua tiav rau tus tswv tsev. Siv SMD cov khoom xyaw, lawv kuj tuaj yeem ua qhov muag me me.
Cov Lus Qhia
Kauj ruam 1
Nrhiav ntawm daim phiaj xwm schematic ntawm lub cuab yeej uas koj xav ua ke ntawm lub hauv paus ntawm lub tsev tsim hluav taws xob microcircuit, ib ntu muaj xws li cov qis hluav taws xob transistors thiab resistors, nrog rau lub zog me me (tsis pub ntau tshaj ob peb puas picofarads) Cov. Seem no yuav tsum muaj ob peb lub ntsiab lus qhov sib txawv rau qhov txuas rau qhov seem ntawm seem - tom qab txhua, qhov no yog raws nraim ntau npaum li cas microcircuit yuav muaj.
Kauj ruam 2
Kos daim duab sib cais ntawm cov qauv ua qauv sab hauv ntawm lub microcircuit. Txheeb cov lej rau nws cov pins, thaum xaiv cov naj npawb ntawm qhov twg, raug coj los ntawm kev yooj yim ntawm kev sib dhos (yuav tsum muaj ob peb txoj kev sib tshuam ntawm tus neeg xyuas pib tsis muaj kev sib txuas) Tsis tas li, cais cais kos duab ntawm lub cuab yeej raws li lub microcircuit no. Xaiv cov tom kawg ua cov duab plaub nrog cov pins, cov zauv ntawm cov khoom sib xws nrog cov uas tau qhia hauv daim duab dhau los.

Sib sau ua ke hluav taws xob sau ntawm cov microcircuit hybrid nyob rau hauv txoj kev yooj yim - ntawm tej yam me me luam tawm lub rooj tsavxwm (suav nrog ib qho tib neeg thoob ntiaj teb) lossis los ntawm cov sib dhos volumetric. Nco ntsoov siv tsuas yog siv cov khoom SMD - tsuas yog ib qho zoo tib yam nkaus xwb tuaj yeem txhim kho qhov ntev ntawm tus qauv. Nws yog qhov ua tau kom txo tau qhov ntom ntawm tus nqi ntawm qee qhov nce hauv ntim los ntawm kev ua rau cov microcircuit multilayer. Hauv qhov no, nws yog ib qho tseem ceeb kom ntseeg tau tias qhov tsis tuaj yeem ua lub voj voog luv ntawm cov khaubncaws sab nraud povtseg uas siv insulating gaskets.

Siv lub tiaj, puag ncig lub thawv ua los ntawm cov khoom siv insulating rau lub tsev rau koj DIY hybrid IC. Hauv qis ntawm nws, txiav kom ntau li cov zis microcircuit muaj. Tom qab muab cov txheej txheem sib dhos hauv rooj plaub, rub cov hlau los ntawm kev txiav, tom qab ntawd rov nruab lub npog thiab lo rau nws nrog Moment kua nplaum lossis lwm yam. Txhawm rau kom tsis txhob muaj qhov tsis quav ntsej ntawm cov kua nplaum vapors, tsis txhob cam lossis siv cov microcircuit kom txog rau thaum cov npoo kom tag. Tsis zoo li niaj hnub monolithic microcircuit, ib qho tshiab uas muaj peev xwm yuav qhib, kho thiab rov ua dua thaum muaj qhov ua tsis tiav. Tab sis qhov teeb meem ntawm kev sib koom ua ke tau qis heev los ntawm cov qauv niaj hnub.
