I-4 Layer ENIG FR4 i-PCB yobhedu olunzima
PCB yobhedu olunzima
Iibhodi zePCB zobhedu ezinzima zinokuveliswa ngokulula ngokudityaniswa kweenkqubo ezimbini eziphambili, i-electroplating kunye ne-etching.Ngokwahlukileyo kwezinye PCBS, isekethe yenziwe umaleko obhityileyo wefoyile yobhedu.
IiPCB zobhedu ezinzima zifakwe ngokulinganayo nge-FR4 okanye ezinye izinto ezisekelwe kwi-epoxy.Umndilili wobunzima beePCB zobhedu ezisindayo zinokuba zii-ounces ezi-4 (140μm), nto leyo engumlinganiselo ongcono kunenye iPCB yobhedu eqhelekileyo.
Ubuninzi bobhedu olongezelelweyo buvumela ibhodi ukuba iqhube imisinga ephezulu, ifezekise ukusabalalisa ubushushu obuhle, kwaye yenza ukuba utshintsho olunzima kwindawo elinganiselweyo.Ezinye iingenelo ziquka ukonyuka kwamandla omatshini kwiindawo zokuxhuma, ukukwazi ukudala ubungakanani beemveliso ezincinci ngokudibanisa ubunzima obuninzi kuluhlu olufanayo lwesekethe, kunye nokukwazi ukusebenzisa izinto ezikhethekileyo ezinomngcipheko omncinci wokungaphumeleli kwesekethe.
Iinzuzo zePCB yobhedu olunzima
Ukwenziwa kwePCBs zobhedu ezinzima kubandakanya ukusetyenziswa kokutyabeka okanye ukukrolwa, njengoko kwandisa ubukhulu bePCB yobhedu kwiindonga ezisecaleni kunye nemingxunya yokwaleka.Ukongeza, i-PCBS yobhedu enzima i-electroplated ngexesha lokwenziwa kwe-PCB.Oku kunceda ukujiya udonga lwePTH kwiPCB.Ezinye iimpawu zePCBS ezishinyeneyo zobhedu ezahlukileyo kwezinye iiPCBS ziquka:
Ubunzima bobhedu:
Oku ngokuqinisekileyo uphawu oluphambili lwePCB yobhedu enzima.Ibhekisa kubunzima bobhedu obusetyenziswa kwisikwere sonyawo kwii-ounces.
Ikhava
Ifoyile yobhedu yangaphandle.Ubunzima bobhedu boluhlu lwangaphandle luyilo oluqhelekileyo olubekwe kwangaphambili.
Uluhlu lwangaphakathi
Umgangatho wobhedu kunye nobukhulu be-dielectric bomgangatho wangaphakathi zizinto ezichazwe kwangaphambili ezisemgangathweni.Nangona kunjalo, zinokuhlengahlengiswa ngokweemfuno ezilungiselelwe iprojekthi.
Ukusetyenziswa kwePCB yobhedu olunzima
IiPCB zobhedu ezinzima zisetyenziswa kwiintlobo ngeentlobo zezicelo, ezifana neziguquli ezisicaba, ukusasazwa kobushushu, ukusasazwa kwamandla aphezulu, abaguquli bolawulo, njl.njl. Kwi-PC, iimoto, ulawulo lomkhosi kunye noomatshini, umdla kwiipleyiti ezityalwe ngobhedu ziyakhula.Iibhodi zeesekethe eziprintiweyo ezinobhedu ezinzima nazo zisetyenziswa ngokubanzi:
1. Unikezelo lwamandla kunye nesiguquli solawulo
2. Igunya lolwabiwo
3. Izixhobo ze-welding okanye izixhobo
4. Ushishino lweemoto
5. Abavelisi beepaneli zelanga, njl
