mmene kusankha pcb zinthu

Ma board osindikizira (PCBs) ndi gawo lofunikira pazida zilizonse zamagetsi zomwe timagwiritsa ntchito masiku ano. Amapereka maziko a zida zamagetsi, kuonetsetsa kuti ntchito yoyenera ndi kugwirizana kwa magetsi. Komabe, popanga PCB, kusankha zida zoyenera kumatha kukhudza kwambiri magwiridwe antchito, kulimba, komanso kutsika mtengo kwa chinthu chomaliza. Mu blog, tiona zinthu zosiyanasiyana kuganizira posankha PCB zipangizo.

Dziwani zambiri za PCB:

Pali mitundu yambiri ya zipangizo PCB, aliyense ndi katundu osiyana ndi ubwino. Zida zina zomwe zimagwiritsidwa ntchito popanga PCB ndi FR-4, Polyimide, Rogers, ndi Aluminium. Pomvetsetsa mawonekedwe azinthuzi, mutha kupanga zisankho zodziwika bwino potengera zomwe mukufuna kupanga.

Zofunika kuziganizira:

1. Katundu Wamagetsi: Mphamvu zamagetsi za zinthu za PCB zimagwira ntchito yofunika kwambiri pozindikira kukwanira kwake pakugwiritsa ntchito inayake. Ganizirani kuchuluka kwa dielectric, kutayika kwa zinthu, komanso kutaya tangent. Zinthu izi zimakhudza kukhulupirika kwa chizindikiro, kuwongolera kwa impedance, ndi kuthekera kogwiritsa ntchito mphamvu.

2. Thermal conductivity and management: Kuthekera kwa zipangizo za PCB kuti zithetse kutentha ndizofunika kwambiri, makamaka pakugwiritsa ntchito mphamvu zambiri. Yang'anani zipangizo zokhala ndi matenthedwe apamwamba kuti muwonetsetse kutentha kwabwino komanso kuchepetsa chiopsezo cha kutenthedwa ndi kulephera kwa gawo.

3. Mphamvu zamakina ndi kukhazikika: Mphamvu yamakina yazinthu za PCB imatsimikizira kukana kwake kupsinjika, kugwedezeka ndi kupindika. Iyenera kupirira mikhalidwe ya chilengedwe yomwe PCB imagwiritsidwa ntchito. Ganizirani zinthu monga kulimba kwamphamvu, flexural mphamvu ndi kukana mphamvu.

4. Mtengo ndi kupezeka: Mtengo ndi kupezeka zingasiyane kwambiri mkati PCB zipangizo danga. Ganizirani za bajeti yoperekedwa ku projekiti ndikuyiyesa molingana ndi zomwe mukufuna. Zida zina zingapereke ntchito zapamwamba koma pamtengo wapamwamba, pamene zina zingakhale zotsika mtengo koma zimakhala ndi zochepa.

5. Njira yopanga: Zida zosiyanasiyana za PCB zimafunikira njira zopangira zosiyanasiyana. Zida zina ndizoyenera kusonkhana kwachikhalidwe kudzera pamabowo, pomwe zina ndizoyenera ukadaulo wapamtunda (SMT). Kumvetsetsa njira yopangira komanso kugwirizanitsa kwazinthu zosankhidwa ndizofunikira kuti tipewe zovuta zopanga.

Nkhani Yophunzira: Kusankha Zida Zoyenera za PCB pazogwiritsa ntchito pafupipafupi:

Tiyeni tilingalire chitsanzo ichi: PCB ndiyofunikira pazida zoyankhulirana zopanda zingwe zothamanga kwambiri. Pankhaniyi, zinthu ngati Rogers PCB zingakhale zabwino. Zida za Rogers zili ndi ma dielectric otsika kwambiri omwe amatsimikizira kutayika kochepa kwa ma siginecha pama frequency apamwamba. Amakhalanso ndi matenthedwe abwino kwambiri, kuwapangitsa kukhala oyenera mapangidwe amphamvu kwambiri omwe amapanga kutentha kwakukulu.

Njira yosankha zinthu za PCB ndi gawo lofunikira pakupanga zida zamagetsi. Poganizira zinthu monga magetsi, matenthedwe amoto, mphamvu zamakina, mtengo, kupezeka, ndi kufananirana ndi kupanga, mutha kusankha zinthu zomwe zikugwirizana ndi zomwe mukufuna. Kumbukirani kusanthula zofunikira za pulogalamu yanu kuti mupange chisankho mwanzeru. Zinthu zosankhidwa bwino za PCB zithandizira magwiridwe antchito komanso kudalirika kwa mapangidwe anu apakompyuta.
