Board-rau- cov khoom sib txuas yog cov khoom tseem ceeb hauv cov khoom siv hluav taws xob niaj hnub no, siv dav hauv cov khoom siv sib txuas lus, cov khoom siv hluav taws xob, kev tswj hwm kev lag luam, cov cuab yeej kho mob, thiab cov khoom siv hluav taws xob hauv tsheb. Lawv lub luag haujlwm tseem ceeb yog tsim kom muaj kev sib txuas hluav taws xob txhim khu kev qha thiab kev kho cov khoom siv ntawm ob lossis ntau dua cov ntawv luam tawm Circuit boards (PCBs), ua kom cov teeb liab kis tau tus mob, kev faib hluav taws xob, thiab kev tsim qauv. As electronic products evolve towards miniaturization, high density, and high performance, the parameter selection and design optimization of board-to-board connectors become particularly important. Lianxin Technology yuav tham txog qhov no hauv kev nthuav dav hauv qab no.
Lub luag haujlwm ntawm Board-rau-Board Connectors
1. Kev sib txuas hluav taws xob muaj nuj nqi: Board- rau- cov khoom sib txuas ua ke feem ntau ua tiav qis -impedance conductive txoj hauv kev ntawm PCBs los ntawm cov hlau hu (xws li kub-plated lossis tin-plated tooj liab alloys), kom ntseeg tau cov teeb liab kev ntseeg siab (SI) thiab hluav taws xob integrity). Piv txwv li, nyob rau hauv 5G lub hauv paus chaw nres tsheb cov cuab yeej, siab -ceev teeb liab kis tau tus mob yuav tsum tau connectors los txhawb cov ntaub ntawv kis tus nqi siab tshaj 10Gbps, thaum tseem yuav txo tau crosstalk thiab teeb liab attenuation.
2. Mechanical Support and Modular Design: Tus naj npawb ntawm mating cycles, vibration resistance, thiab locking qauv ntawm connector ncaj qha cuam tshuam rau kev ntseeg ntawm cov khoom. Piv txwv li, lub rooj tsavxwm-rau- cov khoom sib txuas hauv tsheb hluav taws xob yuav tsum ua tau raws li ISO 16750 tus qauv, tiv taus qhov kub thiab txias, kev co, thiab kev poob siab, thiab ua kom ruaj khov nyob rau hauv ib puag ncig hnyav. Tsis tas li ntawd, cov qauv tsim qauv (xws li cov koob yees duab detachable) cia siab rau cov khoom sib txuas rau kev sib dhos thiab kho sai.
3. Qhov chaw ua kom zoo dua qub thiab siab -Kev sib xyaw kom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom cov khoom siv cov khoom sib txuas. Piv txwv li, 0.4mm pitch miniature board-rau-board connectors txuag PCB chaw, txhawb multi-layer stacking designs, thiab ua tau raws li cov kev cai sab hauv ntawm ultra-thin devices.
Ntsiab Parameter Xaiv Phau Ntawv Qhia
