Iinkonzo zokuVelisa iiPlati zePCB kwiMibala emininzi

Yazisa:

Kwinkalo yokwenziwa kwezixhobo zombane, iibhodi zeesekethe eziprintiweyo (PCBs) zidlala indima ebalulekileyo. Isebenza njengesiseko sezinto ezahlukeneyo zombane kwaye isebenza njengeqonga lokuqhuba imiqondiso kunye namandla kuzo zonke izixhobo zombane. Ngelixa ukusebenza kwe-PCB kunye nokuqina bekusoloko kubalulekile, i-aesthetics kunye nokhetho lokuzenzela luye lwatsala ingqalelo enkulu kwiminyaka yakutshanje.Kule post yebhlog, siza kuphonononga kumbuzo onomdla wokuba ingaba iinkonzo zePCB zokwenziwa kweepleyiti zobhedu zinokubonelela ngeendlela ezininzi zemibala.

Funda malunga nokwenziwa kwepleyiti yobhedu yePCB:

Ukwenziwa kwebhodi yobhedu yePCB kubandakanya inkqubo yokwenza umaleko wobhedu kwibhodi yesekethe kunye nokufunxa ubhedu olungeyomfuneko ukwenza ipateni yesekethe eyiliweyo. Ngaphambili, ubhedu lwalucatshangelwa kuphela kwifom yendabuko, intsimbi ebomvu ebomvu. Nangona kunjalo, ukuqhubela phambili kwetekhnoloji kuvule indlela yeendlela ezintsha ezibandakanya imibala emininzi kwinkqubo yokuvelisa. Ngoku umbuzo uvela; singazifumana iipleyiti zobhedu zePCB ngemibala eyahlukeneyo enomtsalane? Makhe sijonge.

Indlela yesiNtu:

Ngokwemveli, ii-PCBs zenziwe kusetyenziswa umaleko omnye wobhedu, othi emva koko ugqunywe ngomaleko wokugquma ukukhusela iindawo zobhedu eziveziweyo ngexesha lenkqubo yokubhala elandelayo. Emva koko, imaski ye-solder (i-polymer layer) (ikakhulukazi eluhlaza) isetyenziselwa ukubonelela nge-insulation kunye nokukhusela ukujikeleza kobhedu kwizinto ezisingqongileyo. Umbala oluhlaza ngowona mbala uxhaphakileyo kwizixhobo zombane kwaye uphantse wafana nePCB. Nangona kunjalo, njengoko itekhnoloji ihambela phambili, abavelisi ngoku bajonga iindlela zokusuka kuluhlaza wendabuko kwaye bazise izinto ezintsha ezinokwenzeka.

Ukuvela kokhetho lwemibala emininzi:

Kwiminyaka yakutshanje, abavelisi bePCB baye baqala ukwazisa iintlobo ezahlukeneyo zemibala kwiipleyiti zabo zobhedu. Ukongeza kwindalo eluhlaza, eyona nto ixhaphakileyo iluhlaza okwesibhakabhaka, obomvu, omnyama nomhlophe. Le mibala inokongeza umnxeba wobuntu kwizixhobo zombane ngelixa igcina ukusebenza okufanayo kunye nomgangatho njengePCB zemveli. Nokuba yiconsole yokudlala, isixhobo sonyango, okanye nasiphi na esinye isixhobo sombane, ukhetho lombala luyinto ebalulekileyo kuyilo lwemveliso kunye nophawu.

Izinto ezichaphazela ukutshintsha kombala:

Ukwazisa imibala emininzi kwi-PCB yokwenziwa kobhedu akukho ngaphandle kwemingeni yayo. Izinto ezininzi zichaphazela ukufumaneka kunye nomgangatho wokhetho lombala, njengohlobo lwempahla ye-solder mask, izongezo ezisetyenziselwa ukufezekisa umbala ofunekayo, kunye nenkqubo yokuvelisa. Ukongeza, ukuhambelana kombala kunye nonyango olwahlukileyo lomphezulu olufana nokufakwa kwegolide okanye i-OSP (i-organic solderability preservative) kunokubangela imida. Abavelisi kufuneka benze ulungelelwaniso phakathi kobuhle kunye nokusebenza ukuqinisekisa iziphumo ezilungileyo.

Izinto eziluncedo kwiipleyiti zobhedu zePCB ezinemibala:

Uluhlu olubanzi lweenketho zemibala yobhedu lwePCB lubonelela ngeenzuzo ezininzi kubenzi besixhobo sombane kunye nabasebenzisi bokugqibela. Okokuqala, ivumela abavelisi ukuba benze iimveliso ezibukekayo ezibonakala zibalaseleyo kwimarike egcweleyo. IiPCB ezinemibala zinceda ukwahlula iimveliso kunye nokwandisa ukuqondwa kophawu. Ukongeza, iiPCB ezinombala ziphucula ukuqonda okubonakalayo kweenkqubo ze-elektroniki ezintsonkothileyo, zenza kube lula ukulungisa iingxaki kunye nokugcina iingxaki.

Ngaphaya kweAesthetics: Ukusebenza kweePCB eziMbala:

Ngelixa ukhetho lombala lusongeza isibheno sobuhle kwi-PCB, usetyenziso lwazo olusebenzayo luya ngaphaya kwembonakalo. Ngokomzekelo, utshintsho lombala lunokunceda ukuchonga iindawo ezahlukeneyo zesekethe, ukwenza uyilo kunye nenkqubo yokulungiswa kakuhle. Ukongeza, iiPCB ezinombala zinokunceda ukuchonga iindiza eziphantsi komhlaba, ukulandelwa kweempawu, kunye nokuhanjiswa kwamandla, okuluncedo kakhulu kwizicwangciso ezinzima.

Amathuba kunye nemingeni kwixesha elizayo:

Njengoko imfuno yokwenza ngokwezifiso ikhula kwaye itekhnoloji iqhubeka nokuvela, sinokubona ukuvela kokhetho lombala ongaphezulu kwi-PCB yokwenza amaphepha obhedu. Ukudityaniswa kwemibala kunye noyilo oluntsonkothileyo kwiiPCB kunokuba ngumbono oqhelekileyo, uzalisekisa zombini iimfuno ezisebenzayo kunye nobuhle. Nangona kunjalo, kubalulekile ukujongana nemingeni enokubakho njengempembelelo yombala ekusebenzeni kombane kunye nokuthembeka kwexesha elide. Uvavanyo olungqongqo kunye nokuthotyelwa kwemigangatho yoshishino lubalulekile ekuqinisekiseni ukuqina kunye nokusebenza kweePCB zemibala.

Ukuququmbela:

Ilizwe lokwenziwa kwePCB alisekho kuphela ekusebenzeni nasekuzinzeni. Ukwaziswa kokukhethwa kwemibala emininzi kwi-PCB yokwenziwa kweepleyiti zobhedu kuvula iindlela ezinomdla kubenzi kunye nabasebenzisi bokugqibela. Ukukwazi ukwenza izixhobo zombane ngokwezifiso ngeePCB ezibukekayo ngelixa ugcina owona mgangatho uphezulu kunye nokusebenza linyathelo elibhekiselele ekudityanisweni kwezinto ezintsha kunye nobuhle. Njengoko itekhnoloji iqhubela phambili, sinokulindela ukhetho olunamandla kunye nolwahlukeneyo lokwenziwa kwepleyiti yobhedu yePCB, ukubumba ikamva lezixhobo zombane.
