Akadhindwa redunhu bhodhi: tsananguro, izita

The akadhindwa redunhu bhodhi iri STRUCTURAL Kufananidzira kuti unosanganisira dielectric chawo uye mhangura conductors, izvo rakachengetedzwa uri substrate muchimiro metallized zvikamu. Rinotibatsira remubatanidzwa zvigadzirwa redunhu zvinhu.

The redunhu bhodhi rine nhamba zvakanakira ichienzaniswa unorema (inoshandisa dzidziso) kugadzwa kushandisa netambo uye waya:

• High arambe achirema Kubhururuka redhiyo zvinoriumba uye dzavo yeimwe, zvichiguma yekudyidzana akaderedza kukura uye uremu;
• kugamuchira conductors uye kudzivirirwa hukawanika, uye radioactive zvinhu mune rimwe rwokugadzira kutenderera;
• Kugadzikana, repeatability maitiro akadai capacitance, conductance, inductance;
• kumhanya uye ruzha kutapata hushande;
• kuramba zvemaziso uye okunze zvinofurira;
• Standardization uye kubatana zviri zviripo uye magadzirirwo mhinduro;
• kuvimbwa edunhu, dzakabatana uye mudziyo yose;
• nani processability somugumisiro kunzwisisa kushandisa michina rwokuungana kushandiswa, kuzvidzora uye kuchinja kwacho;
• yakaderera basa zvikuru, zvinhu zvinodyiwa uye mari inoshandiswa.

The akadhindwa redunhu Puranga anewo zvainovhiringidzawo, asi ivo vari vakasvimha: zvishoma maintainability uye yakakwirira kunzwisisa zvokuwedzera kugadzira kuchinja.

Chinobatanidza makadhi akadaro anosanganisira dielectric nechigadziko, esimbi unhani, inova mufananidzo conductors akadhindwa, kuonana Mapedhi; kugadzirira uye kuwedzera maburi.

Zvinodiwa kuti dzinoshanda zvigadzirwa izvi GOST

• Akadhindwa redunhu bhodhi inofanira kuva homogeneous ruvara pamusoro dielectric substrate kuti monolithic ari mamiriro, dzisina dzakawanda vesicles, rinosakara, inclusions vatorwa, makatsemuka, machipisi, mwanda. Zvisinei akabvumira anokwenya kuroorwa, simbi inclusions, kubviswa tichingoda neprotravlennogo kuroorwa mugove uye kuratidzwa sechivako iyo haachinji magetsi parameters zvibereko, hazvideredzi zvinobvumidzwa kure pakati nomufananidzo zvinhu.
• Figure - zvakajeka, ane mvere unopinza, hapana Maronda akasiyana, makatsemuka, peeling, chero chokushandisa. Zvishoma echitema vemo, asi kwete kupfuura shanu pfungwa por sikweya decimeter, pamwe proviso kuti vamwe njanji upamhi kuchaita dzinoenderana shoma zvinobvumidzwa; kutsemuka urefu kune millimeters matanhatu uye kudzika 25 microns.

Kuti uvandudze ngura kuita uye kuvandudza solderability bhodhi pamusoro zvemapuranga ne electrolytic sezvamunoita iyo inofanira kuva chinoenderera, pasina peeling, anoputsa uye podgarov. Kugadzirira uye kuwedzera maburi anofanira kuraswa maererano pamufananidzo. Kuva kutsaudzira yakajeka zvakarurama kirasi kubhadhara. Kuti uvandudze rakavimbika pokunamatidza pamusoro romukati hukawanika yose hunowedzera maburi sprayed mhangura layer ane ukobvu zvishoma pane 25 microns. Izvi anonzi - metallization kuti maburi.

Chii pcb makirasi? Pasi pfungwa iyi zvinoreva makirasi zvakarurama kugadzira redunhu mapuranga, ivo yakapiwa GOST 23751-86. Zvichienderana nomufananidzo arambe achirema of akadhindwa redunhu bhodhi rine shanu makirasi zvakarurama, pakusarudza zvakatemwa nokuda hwokugadzira kwemashoko vachida chechetere. Rokutanga uye rechipiri makirasi regai zvinoda zvakarurama michina uye vanoonekwa chisingakoshi kubereka. Rechina nerechishanu makirasi zvinoda anokosha zvinhu, inokosha midziyo, akakwana rucheno mukurima zvivako, mhepo kutonhodza, tembiricha kuzvidzora. Domestic emakambani gobvu kubereka rakadhindwa vematunhu mapuranga mukirasi rechitatu zvakarurama.
