Mphindi imodzi kuti ikuphunzitseni momwe mungasankhire zolumikizira bolodi ndi bolodi

Moni nonse, ndine mkonzi.Pali mitundu yambiri yolumikizira.Mitundu yodziwika bwino imaphatikizapo ma terminals olumikizirana, ma wiring terminals, ma waya-to-board zolumikizira, ndi zolumikizira board-to-board.Gulu lirilonse likhoza kugawidwa m'magulu angapo, monga: zolumikizira bolodi-to-board zikuphatikizapo mitu ndi akazi, zolumikizira bolodi-to-board, ndi zina zotero;mawaya-to-board zolumikizira zikuphatikizapo FPC zolumikizira, zitsulo IDC, zosavuta nyanga sockets, etc. Choncho posankha cholumikizira, ndi ngodya ziti tiyenera kuganizira cholumikizira choyenera kugwiritsa ntchito hardware?

1. Zikhomo ndi mipata

Chiwerengero cha mapini ndi mpata pakati pa mapini ndiwo maziko oyambira kusankha cholumikizira.Chiwerengero cha zikhomo zosankhidwa kuti zigwirizane zimadalira chiwerengero cha zizindikiro kuti zilumikizidwe.Kwa zolumikizira zigamba zina, kuchuluka kwa zikhomo pamitu yachigamba monga momwe tawonetsera pachithunzi pansipa sikuyenera kukhala kochulukirapo.Chifukwa mu ndondomeko ya soldering ya makina oyika, chifukwa cha kutentha kwakukulu, pulasitiki yolumikizira idzatenthedwa ndi kupunduka, ndipo gawo lapakati lidzaphulika, zomwe zimapangitsa kuti zikhomo ziwonongeke.Kumayambiriro kwa pulogalamu yathu ya P800Flash, mutuwu ndi mutu wamayi zidagwiritsidwa ntchito polumikizana ndi board-to-board.Zotsatira zake, zikhomo za mutu wa prototype zidagulitsidwa m'malo akuluakulu.Pambuyo posintha kukhala mitu ya pini 2 yokhala ndi mapini apakati, panalibe zomangira zabodza.

Masiku ano, zida zamagetsi zikukula molunjika ku miniaturization ndi kulondola, ndipo mapini a cholumikizira asinthanso kuchokera ku 2.54mm kupita ku 1.27mm mpaka 0.5mm.Kamvekedwe ka kutsogolera kocheperako, m'pamenenso zimafunika pakupanga zinthu.Kutalikirana kotsogola kuyenera kutsimikiziridwa ndi mulingo waukadaulo wamakampani, kutsata malo ang'onoang'ono

2. Kuchita kwamagetsi

Ntchito yamagetsi ya cholumikizira makamaka imaphatikizapo: kuchepetsa panopa, kukana kukhudzana, kukana kutsekemera ndi mphamvu ya dielectric, etc. Mukagwirizanitsa magetsi apamwamba, tcherani khutu ku malire amakono a cholumikizira;potumiza ma siginecha apamwamba kwambiri monga LVDS, PCIe, etc., tcherani khutu kukana kulumikizana.Cholumikizira chimayenera kukhala chocheperako komanso chosasunthika, nthawi zambiri makumi a mΩ mpaka mazana a mΩ.

3. Kuchita kwa chilengedwe

The chilengedwe ntchito cholumikizira makamaka zikuphatikizapo: kukana kutentha, chinyezi, mchere kutsitsi, kugwedera, mantha, etc. Sankhani mogwirizana ndi malo enieni ntchito.Ngati malo ntchito ndi ndi chinyezi, zofunika kukana chinyezi ndi mchere kutsitsi za cholumikizira ndi mkulu kupewa dzimbiri kukhudzana zitsulo cholumikizira.Pankhani ya kayendetsedwe ka mafakitale, zofunikira zotsutsana ndi kugwedezeka ndi kugwedezeka kwa cholumikizira ndizokwera kwambiri kuti cholumikizira chisagwe panthawi yakugwedezeka.

Mayesero enieni akuwonetsa kuti chifukwa cha njira yapadera ya socket, cholumikizira ichi chimakhala ndi zotsatira zoonekeratu zopusa, mphamvu yaying'ono yoyikapo, mphamvu yolekanitsa pang'ono, komanso kumva bwino kwa plug-in, zomwe zimapangitsa kuti mapulagi azikhala bwino.

Zolumikizira, zomwe nthawi zambiri zimatchedwa zolumikizira ndi mainjiniya, zimagwiritsidwa ntchito kulumikiza matabwa awiri ozungulira kapena zida zamagetsi kuti akwaniritse mphamvu kapena kutumiza ma siginecha.Kupyolera mu cholumikizira, dera likhoza kusinthidwa, njira yopangira zinthu zamagetsi imatha kukhala yosavuta, ndipo mankhwalawo amatha kusamalidwa komanso kukonzedwa mosavuta.Kwa ma modular ma frequency, kusankha kwa zolumikizira kumachita gawo lalikulu.
