Yakakora Sei 1oz Mhangura?

Muindasitiri yebhodhi redunhu rakadhindwa, nzira yakajairika yekutaura ukobvu hwemhangura iri pcb is in ounces (oz). Why use a unit of weight to specify a thickness? Great question! If 1oz (28.35 grams) of copper is flattened to evenly cover 1 square foot of surface area (0.093 square meter), the resulting thickness will be 1.37mils (0.0348mm). A conversion chart for different units of measure can be found below.

Ndinoda Copper yakawanda sei?

Nemuganho wakafara, maPCB mazhinji anogadzirwa ne1oz mhangura pane yega yega. Kana mafaera ako asingasanganisire kudhindwa kwemucheka kana zvimwe zvakatemwa, isu tichafungidzira 1oz yakapedza huremu hwemhangura pane ese mhangura. Kana dhizaini yako ichida yakakwira voltages, kuramba, kana impedances, gobvu mhangura inogona kudikanwa. Pane akati wandei epamhepo maturusi anogona kukubatsira kuona kuti ukobvu, hupamhi kana kureba zviteshi zvako zvinoda kuve kuti uwane zvaunovavarira. Maturusi mashoma akadaro ebato rechitatu akabatanidzwa pazasi. PCB Prime haina hukama nevanyori vezvishandiso izvi.

KUSARUDZA SEI YAKAKODZERA PCB Mhangura ukobvu

Kusarudza iyo yakakwana inorema yemhangura ukobvu kuti uise kune yakapfava kuburikidza negomba (PTH) inotamba yakakosha chinhu chakanangana nekuvimbika kwese kweakadhindwa redunhu bhodhi. Pane zvinhu zviviri zvakakosha zvekufunga nezvazvo pakusarudza yakakwana PCB yemhangura ukobvu. Yekutanga ndiyo yazvino kugona kwebhodhoro rinogamuchirwa kupisa kusimuka. Chechipiri ndiyo michini simba akatemerwa mhangura ukobvu, gomba-saizi uye kana pane chero rubatsiro vias.

Vazhinji vatengi vanoda kuvaka maPCB ane mashandiro akanaka pamutengo wehupfumi. Danho rekutanga nderekusarudza kwakakodzera mhangura ukobvu kune yako PCB mhando. Hunhu hwakasiyana hwehukobvu uhu hwakakosha pakusarudza mabasa, kuita kwePCB. Kana iwe uchida rumwe ruzivo nezve PCB yemhangura ukobvu kusarudzwa kana maitiro ekusarudza yakanakisa sutu PCB yako dhizaini, ndapota taura nesu. Isu tinopa kwete zano rakanaka chete asi mhinduro yakakwana. Iwe uchawana madiki uye akangwara maPCB ane mashandiro akanaka uye kuvimbika kwakanyanya kubva kuYMS.
