Ii-PCB zinika amandla amashishini amaninzi kunye nezixhobo kuluntu lwethu. Njengoko itekhnoloji yethu iguquka, kunjalo nakwimfuno yeentlobo ezahlukeneyo zePCB. Xa ukhetha phakathi kwe-single-layer kunye ne-multi-layer PCBs, ukhetho lubonakala ngathi alunasiphelo. Ngaphambi kokuthenga i-PCB entsha, kubalulekile ukuba uqonde izinto ezilungileyo nezingalunganga zendlela nganye oyikhethayo. Ezi zezinye zezibonelelo zokuthenga multilayer PCB kuyilo olunye-umaleko.

Okokuqala, kubalulekile ukuqonda ukuba yintoni i-PCB ye-multilayer kunye nendlela yokwenza ngayo.

A-maleko-PCB enye ukuba umaleko izinto conductive. Uya kufumana umzobo we-wiring oqhubayo kwicala elinye lebhodi kunye nezinto ezibekwe kwelinye. Ii-PCB ezizodwa zihlala zisetyenziswa kwizixhobo ezilula kuba akukho zingcingo zokuwela zenze umsebenzi wesekethe ngokufanelekileyo. Ii-PCB ezinamacala amabini ziyafana, zinemisebenzi emininzi kuneebhodi eziluhlu olunye, kodwa zingaphantsi kwee-PCB ezininzi. Banobumba obunye bokudlala kwidayelektri kunye nocingo lwensimbi oluqhubayo kwicala ngalinye.

Iibhodi ze-multilayer, kwelinye icala, zintsonkothile kune-single-layer okanye ii-PCB ezisemacaleni. Multilayer PCB iye maleko ezintathu okanye nangaphezulu izinto conductive. Olunye udidi, ihlala ifoyile yobhedu, ibekwe ngaphezulu kwentloko.

Qala ngombindi. Uluhlu ngalunye longezwe ukusukela ngoko alunyangeki kwaphela. Ngale ndlela, umenzi unokuzilungelelanisa ngokuhambelana nomxholo. Emva koko, i-foil iyaqhubeka phambili kwaye inokutshintsha kunye nezinye iindawo ngenkqubo ye-lamination. Uxinzelelo kunye neendlela ezinobushushu obuphezulu kufuneka zisetyenziselwe ukudibanisa umaleko kunye nokuzihlanganisa ngokudibeneyo ngokukhuselekileyo.

I-PCB engatshatanga kunye neyohlukeneyo

Ii-PCBS ze-Multilayer zinezibonelelo ezininzi. Ngokubanzi, ezi bhodi zincinci kwaye zikhaphukhaphu, ezenza ukuba zilungele ii-smartphones okanye iikhompyuter, okanye ezinye iimveliso ezifuna ukupakishwa okungafaniyo. Nazi izibonelelo ezizodwa:

I-PCB eyahlukeneyo ikuvumela ukuba ufumane ukusebenza ngakumbi.

Ukuxinana kwendibano ephezulu kuthetha ukuba ungabandisa ubomi bebhodi yakho.

Isakhiwo silula xa ungadingi zinxibelelanisi zePCBS ezininzi ezizimeleyo.

Inkqubo yokuvavanya ngokungqongqo kwinqanaba lokuvelisa kuthetha ukuba uya kufumana umgangatho ophezulu, iimveliso ezifanelekileyo.

Iimpawu zombane zee-PCBS ezininzi ezikhawulezayo zikhawuleza kuneebhodi eziluhlu olunye.

L Kuxhomekeke kwinani lamanqanaba okhetha ukuwongeza, ii-PCBS ezininzi zihlala zilungile kubume obungqongqo nobuguqukayo.

Ngokwahlukileyo, ngelixa ii-PCBS eziluhlu olunye ziluncedo kwezinye iinkqubo, zikwanazo nezinto ezingalunganga ezingafanelekanga ukungahoywa. Nazi ezinye zezinto ezingeloncedo ngabantu ababodwa:

Ngenxa yokuba iingcingo azikwazi ukuwela, iibhodi eziluhlu olunye zilungele izinto ze-elektroniki ezilula kwaye aziboneleli ngeendlela ezininzi ezisetyenziswayo.

L Nangona ii-PCBS eziluhlu olunye zitshiphu ukuzenza, azihlali ixesha elide njengee-PCBS ezininzi, oko kuthetha ukuba azibizi mali iyonke.

I-PCBS yomaleko omnye ayinakufezekisa isantya soogxa bayo abangaphezulu.

L Iibhodi zesekethe ezinomaleko omnye zilinganiselwe kuyilo lwesekethe yazo kuba zinomqhubi omnye kuphela kwaye umgca ngamnye ufuna indlela yawo.

Nangona ii-PCBS eziluhlu olulodwa lukhetho olwamkelekileyo kuyilo olunoxinano olusezantsi, iimpawu zeePCBS ezininzi zenza ukuba zibe lolona khetho lufanelekileyo kumashishini amaninzi afuna ukhetho oluzinzileyo noluchanekileyo.

Ukusetyenziswa kwe-multilayer PCB

Amashishini amaninzi kunye neemveliso zinokuxhamla kwii-PCBS ezininzi, ngakumbi ngenxa yokuqina kwazo, ukusebenza kunye nokukhanya. Nazi ezinye iimveliso ezihlala zisebenzisa ezi bhodi:

L ikhompyuter

L Ukujonga kwentliziyo

L umlilo

I-LGPS kunye neenkqubo zesathelayithi

L Ulawulo loshishino
