Ukuququzelela Impumelelo yeeProjekthi zabaThengi
Ukuqhekeza iKhowudi yeeBhodi zeCopper eziThick: UkuQonda iPress - Iingxaki zeLamination
Kwicandelo eliguqukayo lokwenziwa kwebhodi yesekethe eprintiweyo (i-PCB), ukuphishekela izinto ezisebenza kakuhle njengeebhodi zobhedu ezixineneyo kube yeyona nto iphambili, ingakumbi kwizicelo ezifuna amandla okuphatha amandla aphezulu, njengeemodyuli zamandla ze-DC ezinamandla aphezulu. Ukudibana kwethu kutshanje nohambo olunzima lomthengi lokufezekisa imveliso ephumelelayo yebhodi yobhedu exineneyo kuyichaza kakuhle imingeni kunye nokuphumelela kweli candelo.
Umthengi, emva kokunyamezela iingxaki ezininzi, ekugqibeleni wajika waya kuthi. Imizamo yabo yangaphambili yokwenza iibhodi zesekethe eziprintiweyo zobhedu ezinobukhulu obungama-22 yayiphazamisekile kukusilela okuqhubekayo. Oku kusilela kwakubangelwa ikakhulu yimicimbi ekwinkqubo yokucinezela, elilinqanaba elibalulekileyo ekuvelisweni kwePCB.
Ngexesha lokucinezela, i-resin ephakathi kweengqimba zobhedu iyahamba ukuze izibophe. Kwimeko yeebhodi zobhedu ezixineneyo, ulawulo lokuhamba kwe-resin luba nzima kakhulu. Enye yezona zinto ziphambili ezibangela ukusilela komthengi yayiyingxaki yokuhamba kwe-resin okugqithisileyo okanye okungalinganiyo, okwaziwa ngokuba yi-"resin bleeding." Xa i-resin ihamba kakhulu okanye ngendlela engalawulekiyo, inokukhokelela kwiingxaki ezininzi. Umzekelo, inokubangela iisekethe ezimfutshane phakathi kweengqimba zobhedu ezikufutshane ukuba i-resin ivala izikhewu phakathi kwazo. Ukusasazwa kwe-resin okungalinganiyo kunokubangela iipropati ze-dielectric ezingahambelaniyo kuyo yonke ibhodi, okuchaphazela ukusebenza kwayo kombane.
Enye into ebalulekileyo enegalelo ekusileleni yayikukulinganisela okubuthathaka phakathi kweengqimba zobhedu obukhulu kunye nokuhamba kwe-resin emaphethelweni obhedu kunye nezinto ze-dielectric. Iingqimba zezona ndawo zisengozini kakhulu ngexesha lenkqubo yokucinezela. Ukuba ubungakanani be-resin egeleza emaphethelweni abulawulwa ngokuchanekileyo, kunokukhokelela kwimiba efana nokuhlukanisa emaphethelweni eengqimba zobhedu. Oku kungenxa yokuba i-resin enganeleyo isenokungabi nanto yaneleyo yokunamathela, ngelixa i-resin egqithisileyo inokudala iindawo zoxinzelelo ezibuthathaka i-bond ngokuhamba kwexesha.
Ubushushu bukwadlala indima ebalulekileyo kwinkqubo yokucinezela i-lamination. Ubushushu ngexesha lokutshiza kufuneka bulawulwe ngononophelo. Ukuba ubushushu buphantsi kakhulu, i-resin isenokungahambi kakuhle, nto leyo ekhokelela ekubeni i-bond ibe buthathaka phakathi kweeleya. Kwelinye icala, ukuba ubushushu buphezulu kakhulu, bunokubangela ukuba i-resin ihambe kakhulu, nto leyo eyandisa ingxaki yokopha kwe-resin. Ukongeza, ubushushu obuphezulu bunokubangela uxinzelelo lobushushu ngaphakathi kwebhodi, nto leyo enokubangela ukugoba okanye ukuqhekeka kweeleya zobhedu.
Iqela lethu leengcali, elinolwazi olunzulu kunye namava amaninzi kwimveliso ye-PCB, lathatha lo mngeni. Saqala ngokwenza uhlalutyo olucokisekileyo lweenkqubo zokwenziwa zangaphambili zomthengi. Sihlolisise iiparameter ze-press-lamination, kubandakanya iiprofayili zobushushu, useto loxinzelelo, kunye nohlobo lwe-resin esetyenzisiweyo. Ngokusekelwe kolu hlalutyo, senze uhlengahlengiso oluninzi kwinkqubo.
Silungise iphrofayili yobushushu ngexesha lokucinezela, siqinisekisa ukuba i-resin ifikelela kwi-viscosity efanelekileyo ukuze ihambe kakuhle ngaphandle kokuntywila. Sikwalungise nezicwangciso zoxinzelelo ukuqinisekisa ukusasazwa ngokulinganayo kwe-resin kuyo yonke ibhodi. Ukongeza, sikhethe i-resin eneempawu zokuhamba ngcono kunye nokuhambelana neengqimba zobhedu obukhulu.
Emva kokusebenzisa olu tshintsho, siphumelele ukuvelisa iibhodi zesekethe eziprintiweyo zobhedu ezinobukhulu obungama-22 zomthengi. Iibhodi zahlangabezana nazo zonke iinkcukacha ezifunekayo ngokubhekiselele ekusebenzeni kombane, ukuthembeka koomatshini, kunye nokuchaneka kobukhulu. Le mpumelelo ayisombululanga nje kuphela imiba yemveliso yomthengi kodwa ikwaqaqambise ukubaluleka kwendlela ecokisekileyo kwinkqubo yokushicilela kwimveliso yeebhodi zobhedu ezinobukhulu.
Ukuqukumbela, ukwenziwa kweebhodi zobhedu obukhulu yinkqubo enzima efuna ulawulo oluchanekileyo kwiinguqu ezininzi, ingakumbi ngexesha lesigaba sokucinezela. Ngokuqonda izizathu ezingundoqo zokusilela kunye nokusebenzisa uphuculo olujoliswe kulo, singazoyisa ezi ngxaki size sivelise iibhodi zobhedu obukhulu obuphezulu ezihlangabezana neemfuno ezifunekayo zezicelo ze-elektroniki zanamhlanje.
