Sau Circuit Court board: piav qhia, los

Cov ntawv luam Circuit Court board yog ib tug yam ntxwv caij uas muaj xws li ib tug dielectric puag thiab tooj liab conductors, uas yog tso rau ib tug substrate nyob rau hauv daim ntawv ntawm cov metallized seem. Nws muab ib tug compound ntawm hluav taws xob Circuit Court hais.

Lub Circuit Court board muaj ib tug xov tooj ntawm zoo piv nrog rau tej (hinged) installation siv cables thiab nyob ntawm tej:

• High ceev mounting ntawm xov tooj cua Cheebtsam thiab lawv lub tebchaw, ua rau nws txo loj thiab nyhav;
• tau txais conductors thiab shielding chaw, thiab tej ntsiab nyob rau hauv ib tug nkaus xwb hauj voj voog;
• stability, repeatability yam ntxwv xws li capacitance, conductance, inductance;
• kev kub ceev thiab cov suab nrov tiv thaiv circuitry;
• kuj mus txhua yam thiab climatic influences;
• standardization thiab kev koom ua ke ntawm kev siv technology tshiab thiab tsim kev daws teeb meem;
• cia siab rau lub rooj sib txoos, cov chav nyob thiab tus ntaus ntawv raws li ib tug tag nrho;
• zoo processability raws li ib tug tshwm sim ntawm txoj automation ntawm los ua ke ua hauj lwm, los tswj thiab hloov haujlwm;
• tsawg zog khov, cov ntaub ntawv uas noj thiab cov nqi.

Cov ntawv luam Circuit Court board kuj muaj drawbacks, tab sis lawv yog cov heev me ntsis: tas maintainability thiab siab complexity ntawm ntxiv tsim kev hloov.

Lub ntsiab ntawm tej cards muaj xws li ib tug dielectric puag, ib tug nws yog xim hlau txheej, uas yog ib tug qauv ntawm cov luam conductors, hu rau los; kho thiab mounting qhov.

Yuav tsum uas siv rau cov khoom GOST

• Sau Circuit Court board yuav tsum tau muaj ib tug homogeneous xim nyob rau hauv dielectric substrate yuav tsum tau monolithic nyob rau hauv cov qauv, tsis txhob muaj internal hlwv, cov dab dej ntxuav, txawv teb chaws inclusions, tej kab nrib pleb, chips, bundles. Txawm li cas los tso cai nkaus xwb khawb, hlau inclusions, tshem tawm ntawm ib co kua nplaum neprotravlennogo ib feem thiab zaub ntawm cov qauv uas tsis hloov qhov hluav taws xob tsis muaj cov khoom, tsis txo cov pub kev ncua deb ntawm cov qauv ntsiab.
• Daim duab - meej, nrog ib tug tus ntug, tsis muaj blisters, tej kab nrib pleb, tshwv, txoj lw cuab tam. Me ntsis lub zos tsuas, tab sis tsis ntev tshaj tsib ntsiab lus ib square decimeter, nrog rau cov proviso hais tias tus so ntawm txoj kev khiav dav yuav sib haum mus rau qhov tsawg kawg nkaus pub; nrib pleb ntev rau millimeters thiab ib tug tob ntawm 25 microns.

Yuav kom txhim kho txoj kev xeb kev kawm thiab txhim kho solderability board nto coated los ntawm electrolytic muaj pes tsawg leeg uas yuav tsum tau tas mus li, tsis muaj tshwv, so thiab podgarov. Kho thiab mounting qhov yuav tsum tau muab pov tseg ntawm nyob rau hauv raws li cov duab. Pub kom muaj ib tug sib txawv txhais raug hauv chav kawm ntawv tus nqi. Nyob rau hauv thiaj li yuav txhim kho cov kev cia siab rau ntawm soldering rau tag nrho cov sab hauv chaw ntawm mounting qhov tsuag tooj liab txheej, uas nws thickness yuav tsum muaj tsawg tshaj 25 microns. Qhov no yog hu ua - metallization ntawm qhov.

Yuav ua li cas yog PCB kawm? Nyob rau hauv cov tswvyim no implies cov chav kawm precision raug Circuit Court laug cam, lawv yog muab los ntawm GOST 23751-86. Nyob ntawm seb tus qauv ceev ntawm cov ntawv luam Circuit Court board muaj tsib cov chav kawm ntawm cov neeg, cov kev xaiv uas yog txiav txim los ntawm cov kev khoom ntawm lub enterprise theem. Cov thawj thiab thib ob cov hoob kawm tsis yuav tsum tau precision cov khoom thiab pom tau hais tias pheej yig rau tsim. Cov plaub thiab tsib chav kawm yuav tsum tau tshwj xeeb cov ntaub ntawv, tshwj xeeb cov khoom, tag nrho huv nyob rau hauv cov chaw ntau lawm, huab cua txias, kub tswj. Domestic qhauj loj ua luam Circuit Court pab ntsa ntawm peb chav kawm ntawv ntawm cov neeg.
