Ifoyile yobhedu yePCB

Ngenxa yokusetyenziswa kakhulu kwezixhobo ze-elektroniki, imfuno yezi zixhobo ibisoloko iphezulu kwimarike. Ezi zixhobo ngoku zisijikelezile njengoko sixhomekeke kakhulu kuzo ngeenjongo ezahlukeneyo. Ngenxa yesi sizathu, ndiyaqiniseka ukuba ufumene isixhobo se-elektroniki okanye uhlala usisebenzisa ekhaya. Ukuba usebenzisa ezi zixhobo, unokuzibuza ukuba izixhobo zesixhobo se-elektroniki zixhunywa njani, zisebenza njani, kwaye isixhobo sinokuqhagamshelwa njani kwezinye izinto. Izixhobo ze-elektroniki esizisebenzisayo ekhaya zenziwe ngezinto ezingasebenzisi umbane. Zineendlela ezikrolwe ngezinto zobhedu eziqhubayo kumphezulu wazo, zivumela isignali ukuba ihambe ngaphakathi kwesixhobo xa sisebenza.

Ngoko ke, iteknoloji ye-PCB isekelwe ekuqondeni ukusebenza kwezixhobo zombane. I-PCB isoloko isetyenziswa kakhulu kwizixhobo ze-elektroniki ezenzelwe izixhobo zemidiya. Nangona kunjalo, kwisizukulwana sanamhlanje, zisetyenziswa kuzo zonke izixhobo ze-elektroniki. Ngenxa yesi sizathu, akukho sixhobo se-elektroniki esinokusebenza ngaphandle kwe-PCB. Le bhlog igxile kwi-copper foil ye-PCB, kunye nendima edlalwa yiifoyile yobhedukushishino lwebhodi yesekethe.

Itekhnoloji yeBhodi yeSekethe ePrintiweyo (PCB)

Ii-PCB ziindlela eziqhuba umbane ezifana nemikhondo kunye neetrekhi, ezifakwe i-laminate nge-copper foil. Oku kuzenza ziqhagamshelane kwaye zixhase ezinye izinto ze-elektroniki eziqhagamshelwe ngoomatshini kwisixhobo. Ngenxa yesi sizathu, umsebenzi ophambili wezi PCB kwizixhobo ze-elektroniki kukubonelela ngenkxaso kwiindlela. Kwiimeko ezininzi, izinto ezifana ne-fiberglass kunye neplastiki zibamba lula i-copper foil kwisekethe. I-copper foil kwi-PCB idla ngokugqunywa nge-substrate engaqhubiyo. Kwi-PCB, i-copper foil idlala indima ebalulekileyo ekuvumeleni ukuhamba kombane phakathi kwezinto ezahlukeneyo zesixhobo, ngaloo ndlela ixhasa unxibelelwano lwazo.

Amajoni ahlala edibanisa ngokufanelekileyo phakathi komphezulu we-PCB kunye nezixhobo ze-elektroniki. Ezi solders zenziwe ngesinyithi esenza zibe yi-glue eqinileyo; yiyo loo nto, zithembekile ekunikezeni inkxaso yoomatshini kwiindawo. Indlela ye-PCB idla ngokugqunywa ngezinto ezininzi ezahlukeneyo ezifana ne-silkscreen kunye neentsimbi ezifakwe i-substrate ukuze zibe yi-PCB.

Indima yefoyile yobhedu kushishino lwebhodi yesekethe

Iteknoloji entsha ethandwayo namhlanje ithetha ukuba akukho sixhobo se-elektroniki esinokusebenza ngaphandle kwe-PCB. Kwelinye icala, i-PCB ixhomekeke kakhulu kubhedu kunezinye izinto. Oku kungenxa yokuba ubhedu lunceda ekudaleni iimpawu ezidibanisa zonke izinto kwi-PCB ukuvumela ukuhamba kombane ngaphakathi kwesixhobo. Ezi zinto zinokuchazwa njengemithambo yegazi emathanjeni e-PCB. Ngenxa yoko i-PCB ayinakusebenza xa iimpawu zingekho. Xa i-PCB ingaphumeleli ukusebenza, isixhobo se-elektroniki siya kulahlekelwa yingcamango yaso, nto leyo eyenza ukuba singabi namsebenzi. Ke ngoko, ubhedu yinxalenye ephambili yokuqhuba i-PCB. I-foil yobhedu kwi-PCB iqinisekisa ukuhamba rhoqo kwemiqondiso ngaphandle kokuphazamiseka.

Izinto zobhedu zisoloko ziyaziwa ngokuba nombane ophezulu kunezinye izinto ngenxa yee-electron ezikhululekileyo ezikhoyo kwiqokobhe lazo. Ii-electron zikhululekile ukuhamba ngaphandle kokuchasana nayo nayiphi na iathom eyenza ubhedu lukwazi ukuthwala iindleko zombane ezihambayo ngokufanelekileyo ngaphandle kokulahleka okanye ukuphazamiseka kwemiqondiso. Ubhedu, olwenza i-electrolyte engalunganga egqibeleleyo, luhlala lusetyenziswa kwii-PCB njengomaleko wokuqala. Ngenxa yokuba ubhedu aluchaphazeleki kakhulu yioksijini engaphezulu, lunokusetyenziswa ziintlobo ezahlukeneyo ze-substrates, ii-insulating layers, kunye neentsimbi. Xa lusetyenziswa nezi substrates, lwenza iipateni ezahlukeneyo kwisekethe, ngakumbi emva kokukrola. Oku kusoloko kwenzeka ngenxa yamandla obhedu okwenza unxibelelwano olugqibeleleyo kunye nee-insulating layers ezisetyenziselwa ukwenza i-PCB.

Kukho iileya ezintandathu zePCB ezenziweyo, apho iileya ezine zikwiPCB. Ezinye iileya ezimbini zihlala zongezwa kwiphaneli engaphakathi. Ngenxa yesi sizathu, iileya ezimbini zezokusetyenziswa ngaphakathi, kukwakho ezimbini zokusetyenziswa ngaphandle, kwaye ekugqibeleni, ezimbini eziseleyo kwiileya ezintandathu zizonke zezokuphucula iipaneli ngaphakathi kwiPCB.

Isiphelo

Ifoyile yekopoloyinxalenye ebalulekileyo ye-PCB evumela ukuhamba kweetshaja zombane ngaphandle kokuphazamiseka. Inomoya ophezulu wokuqhuba kwaye yenza ikhonkco eliqinileyo kunye nezixhobo ezahlukeneyo zokukhusela ezisetyenziswa kwibhodi yesekethe ye-PCB. Ngenxa yesi sizathu, i-PCB ixhomekeke kwi-copper foil ukuze isebenze njengoko yenza uqhagamshelo lwe-PCB skeleton lusebenze ngempumelelo.
