pcb 4 ngodya zowononga terminal

Kufotokozera Kwachidule:

PCB yokhala ndi makona anayi wononga terminal ndi njira yodalirika komanso yophatikizika yolumikizira mawaya-to-board magetsi otetezedwa. Amapangidwa kuti azikhala okhazikika komanso osavuta kuyiyika, terminal iyi imakhala ndi masikweya kapena amakona anayi okhala ndi zomangira zomwe zili pamakona anayi aliwonse, kuwonetsetsa kukhazikika kwamakina komanso kuwongolera bwino.
Wopangidwa kuchokera ku high-conductivity mkuwa kapena aloyi yamkuwa yokhala ndi malata kapena nickel plating, imapereka kukana kukhudzana kochepa komanso chitetezo champhamvu cha dzimbiri. Mapangidwe okwera pamakona anayi amapereka mphamvu zamakina, kuteteza kusuntha kapena kutsekeka pansi pa kugwedezeka kapena kugwiritsidwa ntchito mobwerezabwereza, kumapangitsa kukhala koyenera kuwongolera mafakitale, ma module amagetsi, machitidwe a HVAC, ndi zamagetsi zamagalimoto.
Mtundu woterewu umalola kuyika kwa waya mosavuta ndikumangitsa zomangira pogwiritsa ntchito zida zokhazikika. Zimagwirizana ndi mawaya olimba komanso omangika, omwe amathandiza mitundu yosiyanasiyana ya mawaya. Kulumikizana kwamtundu wa screw kumatsimikizira kudalirika kwa nthawi yayitali komanso kukana kumasuka, ngakhale m'malo ogwedezeka kwambiri.
Malo osungira amatha kugulitsidwa kapena kusindikizidwa mwachindunji pa PCB, yokhala ndi zotchinga zotchingira kapena zotchingira kuti zikwaniritse miyezo yamagetsi apamwamba komanso chitetezo. Ndi miyeso yaying'ono komanso mawonekedwe ocheperako, ndi oyenera kuyika malo okhala ndi malo pomwe akusunga mphamvu zonyamula zamakono.
Mitundu yosinthidwa mwamakonda imapezeka mosiyanasiyana, mitundu ya ulusi, zosankha zomangira, ndi masinthidwe oyika kuti agwirizane ndi zosowa za pulogalamu inayake. Kaya imagwiritsidwa ntchito pogawa mphamvu, kuwongolera ma siginecha, kapena kulumikiza pansi, cholumikizira cha PCB chokhala ndi ngodya zinayi chimapereka magwiridwe antchito komanso kuphatikiza kosavuta mumisonkhano yamakono yama board.
