Kwicandelo lokwenziwa kwezixhobo ze-elektroniki, ukuchaneka kokubhola kweebhodi zesekethe eziprintiweyo (i-PCBS) kubaluleke kakhulu, njengoko kuchaphazela ngokuthe ngqo ukufakwa kwezinto ezilandelayo ze-elektroniki kunye nokusebenza kweesekethe. Ngexesha lokusetyenziswa kweziseko zesinyithi zendabuko, ingxaki yokungcangcazela idla ngokubangela ukuba imingxunya ye-PCB itshintshe, nto leyo eye yaba yingxaki enkulu ethintela ukuphuculwa kokuchaneka kokubhola. Isiseko segranite, esineempawu zaso ezizodwa zomzimba kunye neenzuzo zesakhiwo, sinika isisombululo esisebenzayo kule ngxaki.
Unobangela oyintloko wokuphambuka kwemingxuma yamanzi okubangelwa kukungcangcazela kwesinyithi esityhidiweyo
Ubuninzi bendalo bezinto zesinyithi esityhidiweyo buphantsi kakhulu. Ngexesha lokusebenza kwezixhobo zokugrumba, ingakumbi xa i-drill bit ejikelezayo ngesantya esiphezulu idibana ne-sheet metal, i-resonance inokwenzeka. Olu xinzelelo luya kubangela ukuba isiseko sesinyithi esityhidiweyo sivelise ukungcangcazela okungenakutyeshelwa. Kwanobukhulu bokungcangcazela obuncinci kakhulu buya kuqokelelana rhoqo kwaye bukhuliswe ngexesha lemisebenzi yokugrumba echanekileyo, ekugqibeleni oku kukhokelela ekubeni i-drill bit iphambuke kwindawo yokugrumba eyayimiselwe ekuqaleni. Ngaphezu koko, ukusebenza kokudambisa kwesiseko sesinyithi esityhidiweyo kulinganiselwe, okwenza kube nzima ukunciphisa ngokukhawuleza amandla okungcangcazela, okubangela ixesha elide lokungcangcazela kwaye komeleze ngakumbi izinga lokunciphisa umngxuma.
Iimpawu ezintle kakhulu zokulwa nokungcangcazela kwesiseko segranite
I-Granite ineempawu ezintle kakhulu zokudambisa. Ulwakhiwo lwayo lwangaphakathi lwekristale yezimbiwa luncinci kwaye lunokufunxa kwaye lusebenzise amandla okungcangcazela ngempumelelo. Xa izixhobo zokumba zisebenza kwaye zivelisa ukungcangcazela, isiseko se-granite sinokunciphisa kakhulu ubukhulu bokungcangcazela ngexesha elifutshane kakhulu. Uphando lubonisa ukuba umlinganiselo wokudambisa we-granite uphindwe kaninzi kunowesinyithi esityhidiweyo. Oku kuthetha ukuba inokuguqula uninzi lwamandla okungcangcazela abe ngamandla obushushu kunye nezinye iintlobo zamandla ngephanyazo kwaye iwachithe, ngaloo ndlela inciphisa kakhulu impembelelo yokungcangcazela kwimisebenzi yokumba, iqinisekisa ukuba i-drill bit inokugqobhoza ngokuzinzileyo kwindlela emiselweyo, kwaye inciphise ngempumelelo ukwenzeka kweziganeko ezichaseneyo.
Isiqinisekiso sokuqina okuphezulu kunye nozinzo
Isiseko segranite sikwanokuqina okuphezulu kakhulu nokuzinza. Uxinano lwayo luphezulu kwaye amandla ayo okucinezela aphezulu kakhulu kuneentsimbi eziphothiweyo. Ngexesha lenkqubo yokugrumba, inokumelana noxinzelelo olukhulu olusetyenziswa yi-drill bit kunye noxinzelelo olwahlukeneyo loomatshini oluvela ngexesha lokusebenza kwesixhobo, kwaye ayiguquguquki. Nokuba iphantsi kokusebenza ixesha elide okanye impembelelo encinci yangaphandle, isiseko segranite sinokugcina uzinzo lwesakhiwo sayo kwaye sinikeze iqonga lenkxaso eliqinileyo nelithembekileyo kwisixhobo sokugrumba. Le nkxaso izinzileyo iqinisekisa ukuba iindawo ezinxulumene necandelo ngalinye lesixhobo sokugrumba zihlala zichanekile ngamaxesha onke, ngaloo ndlela iqinisekisa ukuchaneka okuphezulu kokugrumba.
Inzuzo yokuzinza kobushushu ithintela ukungcangcazela okongezelelweyo
Ukongeza ekuchaseni kwayo ukungcangcazela, ukuzinza kobushushu begranite nako kuyamangalisa. Ngexesha lenkqubo yokugrumba, ukungqubana phakathi kwe-drill bit kunye ne-sheet metal kuvelisa ubushushu, kwaye ukusebenza kwezixhobo kunokubangela ukunyuka kobushushu bendawo. Isiseko sesinyithi esityhidiweyo sichaphazeleka kakhulu kukutshintsha kobushushu. Ukwanda kunye nokucutheka kobushushu kunokubangela ngokulula ukuguquguquka kunye nokungcangcazela okongezelelweyo, okuphazamisa ukuchaneka kokugrumba. I-coefficient yokwandiswa kobushushu begranite iphantsi kakhulu. Xa ubushushu butshintshatshintsha, utshintsho lwayo lobukhulu lunokungahoywa. Oku kuthintela ukungcangcazela okongezelelweyo okubangelwa kukuguquguquka kobushushu, kudala imeko yokusebenza ezinzileyo ngakumbi kwimisebenzi yokugrumba, kwaye kunciphisa ngakumbi amathuba okugrumba ngaphandle.
Ekulandeleni imisebenzi yokugrumba ye-PCB echanekileyo kakhulu, isiseko se-granite, esinokuxhathisa ukungcangcazela okugqwesileyo, ukuqina okuphezulu, uzinzo oluphezulu kunye nozinzo olubalaseleyo lobushushu, sisombulula ngempumelelo ingxaki yokunciphisa ukugrumba ebangelwa kukungcangcazela kwesinyithi esenziwe ngezinto ezahlukeneyo. Sibonelela ngenkxaso ethembekileyo ngakumbi kwizixhobo zokugrumba ze-PCB, sincede ishishini lemveliso ye-elektroniki livelise iibhodi zesekethe eziprintiweyo ezikumgangatho ophezulu, kwaye sikhuthaza lonke ishishini ukuba liphuhle kwicala elichanekileyo neliphambili.
