FR-4 Khoom siv yog dab tsi?
FR-4 PCB fabrication siv FR-4 substrate los tsim cov ntawv luam tawm hauv Circuit Court, txuas cov khoom siv hluav taws xob los ntawm cov kab tooj liab kom ua tiav kev sib txuas hluav taws xob thiab cov teeb liab kis. Nws yog siv rau hauv cov tshuab hluav taws xob xws li cov khoom siv hluav taws xob, kev tswj hwm kev lag luam, thiab kev ntsuas los muab kev txhawb nqa thiab kev ua haujlwm hauv Circuit Court rau cov khoom siv.
Qhov zoo:
Hluav taws xob ruaj ntseg
FR-4 PCBs muaj lub zog dielectric siab (20-25 kV / mm) thiab nqus dej tsawg (<0.1%), ensuring reliable signal transmission without breakdown or leakage.
Thermomechanical Reliability
FR-4 substrates muaj qhov kub hloov pauv iav ntawm 130-140℃thiab lub zog tensile ntawm kwv yees li 350-400 MPa, tiv thaiv Circuit Court deformation los yog cov khoom xoob nyob rau hauv qhov kub-kub soldering los yog kev co / poob siab ib puag ncig.
Lub teeb thiab yoog raws
FR-4 muaj qhov ceev ntawm kwv yees li 1.85 g / cm³, ua rau nws sib zog dua hlau substrates. Qhov no txo qhov hnyav hauv cov laug cam los yog cov khoom siv nqa tau yooj yim thaum tuav cov khoom siv dag zog txaus los txhawb cov txheej txheem nyuaj thiab cov khoom sib txuas.
Thaum xaiv FR-4 PCBs
Consumer Electronics
FR-4 PCBs nqa cov chips, resistors, capacitors, thiab sensors, xa cov teeb liab thiab lub zog los ntawm circuitry, ua rau cov khoom siv xws li smartwatches lossis cov chaw taws teeb tswj los sau cov ntaub ntawv, cov ntaub ntawv txheej txheem, thiab kev tswj xyuas lossis kev ua haujlwm.
Kev Tswj Lag Luam
FR-4 PCBs yog siv rau cov tswj, relays, thiab cov khoom siv hluav taws xob, xa cov teeb liab sensor los tswj cov chav nyob, uas tom qab ntawd xa cov lus txib mus rau lub cev muaj zog, li qub, lossis lub tshuab cua sov kom muaj cov cuab yeej siv ua haujlwm raws li kev ua haujlwm ua ntej.
Tswv yim
FR-4 PCBs txhawb nqa fais fab modules, tswj chips, thiab teeb liab interfaces, xa cov ntaub ntawv sensor mus rau kev ua units thiab tswj actuators, xws li twj tso kua mis los yog kub tswj cov cuab yeej, kom ntseeg tau cov kev ua hauj lwm ib txwm ntsuas ntsuas thiab tswj functions.
