E biri ebi circuit osisi: nkọwa, designation

The biri ebi circuit osisi bụ a bughi mmewere na-agụnye a dielectric isi na ọla kọpa na-eduzi, nke na-edebe na a mkpụrụ n'ụdị metallized ngalaba. Ọ na-enye a compound nke electronic circuit ọcha.

The sekit osisi nwere ọtụtụ uru tụnyere nnukwu (hinged) echichi iji Gịnị na wires:

• High njupụta arịọnụ redio components na ha ogige, dapụtara na budata belata size na arọ;
• anata eduzi na echebe ebupụta, na redioaktivu ọcha na otu na nkà na ụzụ okirikiri;
• kwụsie ike, repeatability e ji mara ndị dị otú ahụ dị ka capacitance, conductance, inductance;
• elu na-agba na mkpọtụ ọgụ circuitry;
• iguzogide n'ibu na onodu ubochi mmetụta;
• Standardization na ịdị n'otu nke na nkà na ụzụ na imewe ngwọta;
• pụrụ ịdabere mgbakọ, nkeji na ngwaọrụ dị ka a dum;
• mma processability dị ka a n'ihi nke mgbagwoju akpaaka nke nzukọ arụmọrụ, akara na ukpụhọde arụmọrụ;
• ala oru ike, ihe onwunwe na oriri na-akwụ ụgwọ.

The biri ebi circuit iba-nwere ndọghachi azụ, ma ha bụ ndị ezi a bit: ejedebeghị maintainability na elu mgbagwoju nke na-agbakwunye imewe mgbanwe.

Ọcha nke ndị dị otú ahụ kaadị na-agụnye a dielectric isi, a dara mkpuchi, nke bụ a ụkpụrụ nke e biri ebi na-eduzi, na kọntaktị pad; gwara na-arịọnụ oghere.

• Biri ebi circuit iba ga-enwe a homogeneous na agba na dielectric mkpụrụ na-monolithic na Ọdịdị, adịghị nwere esịtidem vesicles, echekwa, ndị mba ọzọ inclusions, cracks, ibe, n'ùkwù n'ùkwù. Otú ọ dị kwere otu scratches, metal inclusions, mwepụ nke metụtara neprotravlennogo otu òkè na ngosi nke ihe owuwu nke na-adịghị agbanwe eletriki kwa nke ngwaahịa, anaghị belata allowable anya n'etiti ụkpụrụ ọcha.
• Ọgụgụ - doro anya, na a ezigbo onu, dịghị blisters, cracks, ekpepụsị, Chọpụta ngwá ọrụ. Nta obodo stains, ma ọ bụghị ihe karịrị ise ihe kwa square decimeter, na proviso na ndị fọdụrụ nke track obosara ga-ederịta akwụkwọ ozi ahụ kacha nta allowable; ịgbawa ogologo isii millimeters na a omimi nke 25 microns.

Iji melite corrosion arụmọrụ ma melite solderability osisi n'elu ntekwasa site electrolytic mejupụtara nke kwesịrị na-aga n'ihu, na-enweghị ekpepụsị, oge izu na podgarov. Gwara na-arịọnụ oghere ga-ewekarị nke dị na ịbịaru. Hapụrụ nwere a ndiiche kọwaa n'ụzọ ziri ezi na klas ego.
