Bokosi lozungulira: kufotokoza, cholinga

Bwalo lamadontho losindikizidwa ndi chinthu chophatikizapo maziko a dielectric ndi amkuwa amkuwa omwe amagwiritsidwa ntchito ku gawo lapansi ngati ma metallized. Amapereka kugwirizana kwa magulu onse apakompyuta.

Komiti yoyang'anira dera yosindikizidwa ili ndi ubwino wambiri poyerekezera ndi kukwera kwa volumetric (hinged) pogwiritsa ntchito zingwe ndi waya:

• Kuthamanga kwakukulu kwa kukhazikitsidwa kwa zigawo za wailesi ndi malumikizano awo, zomwe zimapangitsa kuti kuchepetsedwa kwakukulu muyeso yonse ndi kulemera kwa mankhwala;
• Kupeza ma conductor ndi malo otetezera, komanso ma radioelements mu kayendedwe kamodzi kachipangizo;
• Kukhazikika, kubwerezabwereza kwa zikhalidwe monga chidziwitso, kupititsa patsogolo, kupondereza;
• Kuthamanga kwapamwamba ndi phokoso lopanda chitetezo cha maulendo;
• Kukana kwa zisonkhezero zamakina ndi nyengo;
• Kuyanjanitsa ndi kugwirizana kwa njira zowonjezera zamakono;
• Kudalirika kwa mayunitsi, maunitelo ndi chipangizo chonse;
• Kuchulukanso kwachulukidwe chifukwa cha ntchito yowonongeka yothandizira msonkhano komanso ntchito zowonongeka;
• Kusagwira ntchito mochepa, kugwiritsira ntchito zinthu komanso mtengo.

Komiti yoyang'anira dera imakhalanso ndi zovuta, koma pali ochepa mwa iwo: kuchepetsa kuchepa komanso kusinthasintha kwakukulu kwa kuwonjezera kusintha kwa mapangidwe.

Zida za matabwa amenewa ndizo: maziko a dielectric, zokutidwa ndi zitsulo, zomwe ndi chithunzi cha ojambula osindikizidwa, makalata olankhulana; Kukonza ndi mabowo okwera.

Zofunikira, zomwe zimapangitsa kuzinthu izi GOST

• Mapulogalamu omwe amajambula ayenera kukhala ndi yunifolomu mumtundu wa dielectric, womwe umayenera kukhala wotchedwa monolithic, wosakhala ndi mavubu amkati, zipolopolo, zozizwitsa zakunja, mapiko, chips, ndi makina. Komabe, zokopa zokhazokha, zitsulo zothandizira, zowonongeka kwa malo osaloledwa, komanso kuwonetsera kwasinthidwe kosasintha magetsi a chipangizochi, amaloledwa, sichichepetsa mtunda wokaloledwa pakati pa zinthu za chiwerengerocho.
• Chiwerengerocho ndi chowoneka bwino, chokhala ndi malire, popanda mabulters, misonzi, mawotchi, zida zamatsenga. Zopanda malire zam'derali zimaloledwa, koma osati zoposa zisanu pa digimita imodzi, kupatula kuti mbali yonse ya msinkhuyo ikugwirizana ndi zochepa zomwe zimavomerezedwa; Zithunzi mpaka mamita asanu ndi limodzi ndi kuya kwa microns 25.

Poonjezera maonekedwe a kutupa ndi kuonjezera solderability, pamwamba pa bolodi ili ndi mawonekedwe a electrolytic, omwe ayenera kukhala opitilira, opanda zitsulo, misonzi ndi zinyalala. Kukonza ndi mabowo okwera ayenera kukhala molingana ndi kujambula. Amaloledwa kukhala ndi zopotoka zotsatiridwa ndi gulu lolondola la gululo. Pofuna kuwongolera kudalirika kwa soldering pazitsulo zonse za mkati mwa mabowo okwera, mkuwa wochuluka umayikidwa, ndipo makulidwe ake ayenera kukhala osachepera 25 microns. Ndondomekoyi imatchedwa - metallization ya mabowo.

Kodi makalasi a PCB ndi ati? Mawu awa amatanthawuza magulu a kulondola kwa bolodi kupanga, amaperekedwa mu GOST 23751-86. Malingana ndi kuchuluka kwa chithunzichi, PCB ili ndi makalasi asanu oyenerera, omwe amasankhidwa ndi mlingo wa zipangizo zamakono za malonda. Maphunziro oyambirira ndi achiwiri samasowa zipangizo zamakono ndipo amawonedwa kuti ndi otsika mtengo. Gulu lachinayi ndi lachisanu likufuna zipangizo zapadera, zipangizo zamakono, ukhondo weniweni m'mapangidwe opangira, mpweya wabwino, kusunga ulamuliro wa kutentha. Makampani apanyumba akupanga mapepala ozungulira omwe amasindikizidwa mu kalasi yachitatu yolondola.
