6 Lakabka FR4 ENIG Xakamaynta Impedance PCB
Waa maxay sababta PCB ay u Samayso Culays?
PCB impedance waxaa loola jeedaa iska caabinta iyo xuduudaha falcelinta, kaas oo u dhaqma sidii caqabad ku ah beddelka hadda.Ka-hortagga wax-ka-qabashada waxay lagama maarmaan u tahay PCB.Waa tan sababta:
1, PCB si ay u tixgeliyaan rakibaadda fur ee qaybaha elektiroonigga ah, SMT patch plug sidoo kale waxay u baahan tahay inay tixgeliso dhaqdhaqaaqa iyo waxqabadka gudbinta calaamadaha, sidaas darteed waxay u baahan doontaa hoos u dhigista hoose, ka sii fiican.
2, PCB ee geeddi-socodka wax soo saarka iyada oo loo marayo dhigaalka naxaas ah, daasadda electroplating (ama dahaadhay electroless, daasadda kulul buufin kulul), alxanka xiriiriyaha iyo hababka kale, alaabta loo isticmaalo waa inay ahaataa iska caabin hoose, si loo hubiyo in qiimaha impedance guud ee guddiga wareegga si ay u kulmaan. shuruudaha tayada alaabta, si ay u shaqeeyaan caadiga ah.
3, daasadda PCB waa kuwa ugu nugul dhibaatooyinka soo saarista PCB oo dhan, waa isku xirka muhiimka ah ee saameeya xannibaadda;Ciladdeeda ugu weyni waa oxidation fudud ama deliquesce, brazing liidata, si PCB ay u adagtahay in la alxanayo, impedance aad ayuu u sarreeyaa, taasoo keentay in waxqabadka xun ee PCB uusan xasilin.
4, kaari ee PCB waxay yeelan doontaa noocyo kala duwan oo gudbinta signalada, line laftiisa ay sabab u tahay etching, dhumucdiisuna lamination, width silig iyo arrimo kale, waxay keeni doontaa isbeddelka qiimaha impedance, samaynta qallooca signal, taasoo keentay in waxqabadka wareegga hoos u dhaca guddiga, sidaas darteed waxaa lagama maarmaan ah in la xakameeyo qiimaha impedance gudahood xad gaar ah.
