Looxyada Wareega ee Daabacan ee FR4 oo laba-lakab ah ayaa lagu dabaqay kiniiniyada
1. Awood qaybinta: Awood qaybinta kombuyuutarka kiniinka wuxuu qaataa laba-lakab FR4 PCB. PCB-yadani waxay awood u siinayaan dariiq hufan oo xadhkaha korantada si loo hubiyo heerarka korantada saxda ah iyo qaybinta qaybaha kala duwan ee tablet-ka, oo ay ku jiraan bandhigga, processor-ka, xusuusta iyo qaybaha isku xidhka.
2. Jidka ishaarada: Laba-lakab ee FR4 PCB waxa uu bixiyaa fiiloyinka lagama maarmaanka u ah gudbinta signalada ee u dhexeeya qaybaha kala duwan iyo qaybo ka mid ah kumbuyuutarka tablet-ka. Waxay isku xiraan wareegyada isku dhafan ee kala duwan (ICs), xirayaasha, dareemayaasha, iyo qaybaha kale, iyagoo hubinaya isgaarsiinta saxda ah iyo wareejinta xogta ee aaladaha dhexdooda.
3. Kordhinta Qaybaha: Laba-lakab ee FR4 PCB waxaa loogu talagalay in lagu rakibo qaybaha kala duwan ee Surface Mount Technology (SMT) ee kiniinka. Kuwaas waxaa ka mid ah microprocessors, modules xusuusta, capacitors, resistors, wareegyada isku dhafan iyo xirayaasha. Qaabaynta iyo naqshadaynta PCB waxay hubisaa kala dheeraynta habboon iyo habaynta qaybaha si loo wanaajiyo shaqada loona yareeyo faragelinta calaamadaha.
4. Cabbirka iyo isafgaradka: FR4 PCB-yada waxaa lagu yaqaanaa adkeysigooda iyo muuqaalkooda khafiifka ah, taasoo ka dhigaysa kuwo ku habboon in loo isticmaalo aaladaha is haysta sida tablet-yada. Laba-lakab ee FR4 PCB-yada waxay u oggolaanayaan cufnaanta qaybaha baaxadda leh ee meel xaddidan, taasoo awood u siinaysa soo-saareyaasha inay naqshadeeyaan kiniinnada khafiifka ah iyo kuwa fudud iyada oo aan waxyeello loo geysanayn shaqeynta.
5. Waxtarka-kharashka: Marka la barbar dhigo substrate-ka PCB ee horumarsan, FR4 waa shay la awoodi karo. Laba-lakab ee FR4 PCBs waxay bixiyaan xal-wax-ku-ool ah oo loogu talagalay soosaarayaasha kiniinka kuwaas oo u baahan inay hoos u dhigaan kharashka wax soo saarka iyaga oo ilaalinaya tayada iyo isku halaynta.
Sidee labada lakab ee FR4 looxyada wareegga ee daabacan ay kor ugu qaadaan waxqabadka iyo shaqeynta kiniinka?
1. Diyaaradaha dhulka iyo korantada: Laba-lakab ee FR4 PCBs caadi ahaan waxay leeyihiin diyaarado dhul iyo koronto si ay gacan uga geystaan dhimista buuqa iyo sare u qaadida qaybinta korontada. Diyaaradahani waxay u dhaqmaan sidii tixraac deggan oo loogu talagalay daacadnimada calaamadaha waxayna yareeyaan faragelinta wareegyada iyo qaybaha kala duwan.
2. Jidka impedance ee la kontoroolo: Si loo hubiyo gudbinta calaamadaha la isku halayn karo oo loo yareeyo hoos u dhigista calaamadaha, dariiqa xakamaynta impedance ayaa loo isticmaalaa naqshadaynta laba-lakab ee FR4 PCB. Raad-raacyadan waxaa si taxadar leh loogu qaabeeyey ballac gaar ah iyo kala fogaansho si ay u buuxiyaan shuruudaha xannibaadda ee calaamadaha xawaaraha sare leh iyo is-dhexgalka sida USB, HDMI ama WiFi.
3. EMI/EMC gaashaan: Laba-lakab FR4 PCB waxay isticmaali kartaa tignoolajiyada gaashaanka si ay u yarayso faragelinta korantada (EMI) oo ay u hubiso ku habboonaanta korantada (EMC). Lakabyada naxaasta ah ama gaashaanka ayaa lagu dari karaa naqshadda PCB si loo go'doomiyo wareegga xasaasiga ah ee ilaha EMI ee dibadda loogana hortago qiiqa faragelin kara aaladaha ama nidaamyada kale.
4. Tixgelinta naqshadaynta heerka-sare: Kiniinnada ka kooban qaybaha soo noqnoqda sare ama modules sida isku xirka gacanta (LTE/5G), GPS ama Bluetooth, naqshadeynta laba-lakab ee FR4 PCB waxay u baahan tahay inay tixgeliso waxqabadka sare ee soo noqnoqda. Tan waxaa ka mid ah isbarbardhigga isdhaafsiga, hadalka isdhaafka ah ee la kantaroolo iyo farsamooyinka RF ee saxda ah si loo hubiyo hufnaanta calaamadaha ugu wanaagsan iyo luminta gudbinta ugu yar.
