Kwintsimi yokwenziwa kwezixhobo zombane, ukuchaneka kokugaya iibhodi zeesekethe eziprintiweyo (PCBS) kubaluleke kakhulu, njengoko kuchaphazela ngokuthe ngqo ukufakwa kwamacandelo e-elektroniki alandelayo kunye nokusebenza kweesekethe. Ngexesha lokusetyenziswa kweziseko zentsimbi yesiko, ingxaki yokungcangcazela ihlala ibangela ukuba imingxunya yePCB itshintshe, nto leyo eye yaba yingxaki enkulu ethintela ukuphuculwa kokuchaneka kokomba. Isiseko segranite, esineempawu ezikhethekileyo zomzimba kunye neenzuzo zesakhiwo, sibonelela ngesisombululo esisebenzayo kule ngxaki.
Oyena nobangela wokunxaxha kwequla okubangelwa kukungcangcazela kwentsimbi
I-frequency yendalo ye-cast iron material iphantsi. Ngexesha lokusebenza kwezixhobo zokugaya, ngakumbi xa i-drill ejikelezayo ejikelezayo idibana nentsimbi yentsimbi, i-resonance iyakwazi ukwenzeka. Le resonance iya kubangela ukuba isiseko sentsimbi sivelise ukungcangcazela okungenakungahoywa. Kwanobukhulu bokungcangcazela buncinci kakhulu buya kuthi gqolo buqokelelwe kwaye bukhuliswe ngexesha lemisebenzi yokomba echanekileyo, ekugqibeleni ikhokelele kwi-drill bit ephambukayo kwindawo yokuqala esetwe kuyo. Ngaphaya koko, ukusebenza kokumanzisa kwesiseko sentsimbi etyhidiweyo kulinganiselwe, nto leyo eyenza kube nzima ukuthomalalisa ngokukhawuleza amandla okungcangcazela, okukhokelela kubude bexesha lokungcangcazela kwaye kuqinise ngakumbi iqondo lokuthotywa kwequla.
Iimpawu ezibalaseleyo zokuchasana nokungcangcazela kwesiseko segranite
IGranite ineempawu ezibalaseleyo zokudambisa. Isakhiwo sayo sangaphakathi sekristale yamaminerali sihlangene kwaye sinokuthatha ngokufanelekileyo kwaye sisebenzise amandla okungcangcazela. Xa isixhobo sokugaya sisebenza kwaye sivelisa ukungcangcazela, isiseko segranite sinokunciphisa kakhulu i-amplitude ye-vibration ngexesha elifutshane kakhulu. Uphando lubonisa ukuba umlinganiselo wokudambisa we-granite uliphindaphinda kaninzi kunentsimbi ekhandiweyo. Oku kuthetha ukuba inokuguqula uninzi lwamandla okungcangcazela abe ngamandla obushushu kunye nezinye iindlela zamandla ngephanyazo kwaye iwachithe, ngaloo ndlela inciphisa kakhulu impembelelo yokungcangcazela kwimisebenzi yokugrumba, iqinisekisa ukuba i-drill bit ingagrumba ngokuzinzileyo ecaleni kwendlela emiselwe kwangaphambili, kunye nokunciphisa ngempumelelo ukwenzeka kwe-offset phenomena.
Isiqinisekiso sokuqina okuphezulu kunye nokuzinza
Isiseko segranite sikwanazo nokuqina okuphezulu kakhulu kunye nokuzinza. Ubuninzi bayo buphezulu kwaye amandla ayo acinezelayo aphezulu kakhulu kunentsimbi etyhidiweyo. Ngexesha lenkqubo yokomba, inokumelana noxinzelelo olukhulu olusetyenziswa yi-drill bit kunye noxinzelelo olwahlukeneyo lomatshini oluveliswa ngexesha lokusebenza kwesixhobo, kwaye alufanelwanga nokuguqulwa. Nangona phantsi kokusebenza kwexesha elide eliqhubekayo okanye impembelelo encinci yangaphandle, isiseko segranite sinokugcina ukuzinza kwesakhiwo sayo kwaye sinikeze iqonga eliqinileyo nelithembekileyo lenkxaso yezixhobo zokugaya. Le nkxaso ezinzileyo iqinisekisa ukuba izikhundla ezihambelanayo zecandelo ngalinye lezixhobo zokugaya zihlala zichanekile ngamaxesha onke, ngaloo ndlela ziqinisekisa ukuchaneka okuphezulu kokomba.
Inzuzo yokuzinza kwe-thermal igwema i-vibration eyongezelelweyo
Ukongeza kwi-vibration yayo, ukuzinza kwe-thermal ye-granite nayo ibalasele kakhulu. Ngethuba lenkqubo yokugaya, ukungqubuzana phakathi kwe-drill bit kunye ne-sheet sheet kuvelisa ukushisa, kunye nokusebenza kwezixhobo kunokubangela ukunyuka kweqondo lokushisa kwendawo. Isiseko sentsimbi etyhidiweyo sichaphazeleka kakhulu ngokutshintsha kweqondo lokushisa. Ukwandiswa kwe-thermal kunye nokunciphisa kunokubangela ukuba kube lula ukuguqulwa okongeziweyo kunye nokungcangcazela, okuphazamisa ukuchaneka kokugaya. I-coefficient yokwandiswa kwe-thermal ye-granite iphantsi kakhulu. Xa iqondo lobushushu liguquguquka, utshintsho lwe-dimensional yalo luphantse lungahoywa. Oku kunqanda ukungcangcazela okongeziweyo okubangelwa yi-thermal deformation, kudala indawo yokusebenza ezinzile ngakumbi kwimisebenzi yokomba, kwaye kunciphisa ngakumbi amathuba okuba ne-drilling offset.
Ekulandeleni imisebenzi yokugaya i-PCB echanekileyo ephezulu, isiseko segranite, esinokumelana nokungcangcazela okugqwesileyo, ukuqina okuphezulu, ukuzinza okuphezulu kunye nokuzinza okubalaseleyo kwe-thermal, kusombulula ngokufanelekileyo ingxaki yokucima i-drilling ebangelwa yi-iron vibration evela kwiinkalo ezininzi. Ibonelela ngenkxaso ethembeke ngakumbi yezixhobo zokomba zePCB, inceda ishishini lokuvelisa i-elektroniki livelise iibhodi zesekethe ezikumgangatho ophezulu eziprintiweyo, kwaye ikhuthaza ishishini liphela ukuba liphuhlise ngendlela echanekileyo nephambili.
