Kwicandelo lokwenziwa kwezixhobo ze-elektroniki, ukuchaneka kwemveliso yeebhodi zesekethe eziprintiweyo (i-PCBS) kunxulumene ngokuthe ngqo nokusebenza kunye nomgangatho weemveliso ze-elektroniki. Njengezixhobo eziphambili kwinkqubo yokugrumba, uzinzo lokusebenza kunye nokuchaneka kokucubungula izixhobo zokugrumba ze-PCB kubaluleke kakhulu. Phakathi kwazo, into edla ngokunganakwa kodwa ebaluleke kakhulu - isiseko segranite - kukugqiba ngokuzolileyo ukuba amandla ezixhobo anokwandiswa na.
Iingenelo ezikhethekileyo zeziseko zegranite
Uzinzo olubalaseleyo, olumelana nokuphazamiseka kokungcangcazela
Ngexesha lenkqubo yokugrumba i-PCB, i-drill bit ijikeleza ngesantya esiphezulu ukuze isike ibhodi, ivelise ukungcangcazela okuqhubekayo nokuntsonkothileyo. Isiseko se-granite, esinesakhiwo sayo esixineneyo nesifanayo esenziwe ziinkqubo zejoloji kwiminyaka engamakhulu ezigidi, sinokusebenza okunamandla kakhulu kwe-seismic. I-granite esemgangathweni ophezulu emelwe yi-"Jinan Green" iqinile kwi-texture kwaye inokufunxa ngempumelelo kwaye isasaze amandla okungcangcazela aveliswa kukusebenza kwezixhobo, iqinisekisa uzinzo lwezixhobo zokugrumba ngexesha lokusebenza. Xa kuthelekiswa nezinye iziseko zezinto, i-granite inokunciphisa kakhulu impembelelo yokungcangcazela ekuchanekeni kokubekwa kwe-drill bit, okwenza ukuchaneka kwendawo yemingxunya egrunjiweyo kuphakame kwaye ukuphambuka kulawulwa ngaphakathi koluhlu oluncinci kakhulu, ukuhlangabezana neemfuno zokugrumba ezichanekileyo kakhulu zemingxunya emincinci kunye nobubanzi bemingxunya emincinci kwiibhodi ze-PCB ezinoxinano olukhulu.
Ubunzima obuphezulu kunye nokumelana nokuguguleka kuqinisekisa ukuchaneka kwexesha elide
Imisebenzi yokugrumba rhoqo ibangela umngeni omkhulu ekuchaseni ukuguguleka komphezulu wesiseko. Ubunzima be-Mohs be-granite bunokufikelela kwi-6 ukuya kwi-7, budlula kakhulu obo be-common metals kunye ne-engineering plastics ezininzi. Olu phawu lobunzima obuphezulu lwenza isiseko se-granite sihlale sithe tyaba kwaye sigudile kumphezulu waso nokuba siphantsi kwamandla okuchaphazeleka kunye nokungqubana kwe-drill bit ixesha elide. Kwanasemva kwemisebenzi emininzi yokugrumba, inqanaba lokuguguleka alinamsebenzi, ngaloo ndlela kuqinisekiswa ukusebenza okuzinzileyo kwexesha elide kwezixhobo zokugrumba kunye nokuchaneka kokugrumba okuqhubekayo. Oku kubaluleke kakhulu kumashishini amakhulu okuvelisa i-PCB. Kunokunciphisa ixesha lokungasebenzi kwezixhobo kunye nexesha lokugcinwa elibangelwa kukuguguleka kwesiseko, ukuphucula ukusebenza kakuhle kwemveliso kunye nokunciphisa iindleko zemveliso iyonke.
Ukwanda okuphantsi kobushushu kunye nokuncitshiswa, okulungelelaniswe notshintsho lobushushu
Kwi-workshop yokwenziwa kwe-PCB, ubushushu obujikeleze umhlaba buyatshintshatshintsha ngenxa yezinto ezinje ngamaxesha onyaka kunye nokuchithwa kobushushu bezixhobo. Isiseko esenziwe ngezinto eziqhelekileyo sinokwanda okucacileyo kobushushu kunye neziganeko zokucotha, eziya kubangela utshintsho kwiindawo ezihambelanayo zezixhobo kwaye ngaloo ndlela zichaphazele ukuchaneka kokubhola. I-Granite ine-coefficient ephantsi kakhulu yokwandiswa kobushushu. Umzekelo, i-coefficient yokwandiswa okuthe ngqo kwe-granite eqhelekileyo imalunga ne-4.6×10⁻⁶/℃. Xa ubushushu butshintsha, ubungakanani besiseko se-granite buhlala bufana, bubonelela ngesiseko esizinzileyo nesithembekileyo senkxaso yezixhobo zokubhola. Nokuba kusehlotyeni elishushu okanye ebusika obubandayo, izixhobo zinokugcina imeko yokubhola echanekileyo, ziqinisekisa ukuhambelana komgangatho wokubhola kwiibhetshi ezahlukeneyo zeemveliso ze-PCB.
Lungisa indlela yokusebenza kwezixhobo zokugrumba ze-PCB
Ukufakela ngokuchanekileyo kunye nokubeka indawo kubeka isiseko sokuchaneka
Ngexesha lokucubungula isiseko segranite, ngokusebenzisa iindlela eziphambili zokusika nokugaya iidayimani, ukuthamba okuphezulu kakhulu kunye nokuchaneka okulinganayo kunokufezekiswa. Umzekelo, ukunyamezela ukuthamba kweziseko zegranite ezichanekileyo ngaphakathi koluhlu lwe-1m×1m kunokulawulwa kungabi ngaphezu kwe-4μm. Oku kwenza ukuba izixhobo zokubhola zifakwe ngokukhawuleza nangokuchanekileyo ngokusekelwe kwiplani echanekileyo kunye nolwakhiwo lokubeka isiseko, kunye nokuphambuka okuncinci kokufakwa kwecandelo ngalinye. Ukufakwa ngokuchanekileyo kunye nokubeka kubonelela ngesiqinisekiso sokuhamba ngokuchanekileyo kwe-drill bit ngexesha lokusebenza okulandelayo kwesixhobo, ukuphucula ukuchaneka kokubhola ukusuka kumthombo kunye nokunciphisa ngempumelelo iingxaki ezifana nokuphambuka kwendawo yemingxunya kunye nobubanzi bemingxunya obungahambelaniyo obubangelwa kukufakelwa kwezixhobo okungafanelekanga.
Ukuphucula ukuqina kwesakhiwo kunye nokuphucula uzinzo lokusebenza
Xa izixhobo zokugrumba ze-PCB zisebenza, ukongeza ekungcangcazeleni kwazo, zinokuchaphazeleka kukuthuthwa kwangaphandle, umgangatho weworkshop ongalinganiyo kunye nezinye izinto. Isiseko segranite sinobunzima obuphezulu kunye nokuqina okuqinileyo. Emva kokuba sidityaniswe ngokusondeleyo nesakhiwo esiphambili sesixhobo, sinokuphucula kakhulu ukuqina kwesakhiwo sesixhobo sonke. Xa isixhobo sichaphazeleka ngamandla angaphandle okanye ukungcangcazela, isiseko segranite sinokusasaza ngokulinganayo amandla okungqubana ngokuqina kwaso okuqinileyo, sithintele ukuba izinto ezibalulekileyo zesixhobo zingasuswa okanye ziguquguquke ngenxa yamandla angalinganiyo, kwaye siqinisekise ukusebenza okuzinzileyo kwesixhobo phantsi kweemeko zokusebenza ezinzima. Imeko yokusebenza ezinzileyo inceda ukwandisa ubomi benkonzo yesixhobo kwaye ibonelela ngendawo yokusebenza ezinzileyo nethembekileyo yokugrumba okusemgangathweni ophezulu ngaxeshanye.
Isiphumo sokwenyani sesicelo semveliso
Imveliso ye-PCB yeemveliso zabathengi ze-elektroniki
Kwimveliso ye-PCBS yeemveliso ze-elektroniki zabathengi ezifana neefowuni eziphathwayo kunye neekhompyutha zethebhulethi, imfuneko yokuchaneka kokubhola iphezulu kakhulu. Emva kokuba ishishini lokuvelisa i-elektroniki elaziwayo lizise izixhobo zokubhola ze-PCB ezixhotyiswe ngeziseko zegranite, izinga lemveliso lenyuke ukusuka kwi-80% yokuqala ukuya ngaphezulu kwe-90%. Iingxaki ezinje ngoqhagamshelo olubi lwemigca kunye nokujikeleza okufutshane okubangelwa kukuchaneka kokubhola okungonelanga zincitshisiwe kakhulu. Okwangoku, ngenxa yokunciphisa ukuphindaphindwa kwesiseko segranite kokugcinwa kwezixhobo, amandla emveliso yenyanga yale shishini anyuke nge-20%, nto leyo eyehlisa ngokufanelekileyo iindleko zemveliso ngeyunithi nganye yemveliso kwaye iphumelela ixabiso kunye nenzuzo yomgangatho kukhuphiswano olukhulu lwemarike.
Ukuveliswa kweebhodi zolawulo lwemizi-mveliso ze-PCBS
Indawo yokusebenza yeebhodi zolawulo lwemizi-mveliso iyinkimbinkimbi, kwaye iimfuno zokuthembeka ze-PCBS zingqongqo. Inkampani egxile ekuveliseni iibhodi zolawulo lwemizi-mveliso ibone ukunyuka okukhulu kwinqanaba lokupasa kweebhodi zayo ze-PCB kwiimvavanyo ezinzima zokusingqongileyo ezifana nobushushu obuphezulu kunye nokufuma okuphezulu emva kokusebenzisa izixhobo zokumba ezineziseko zegranite. Uzinzo oluphuculweyo lokusebenza kwezixhobo lwenza umgangatho wokumba uthembeke ngakumbi, ukubonelela ngesiqinisekiso esiqinileyo sokusebenza okuzinzileyo kwexesha elide kwebhodi yolawulo lwemizi-mveliso. Ngeemveliso ezisemgangathweni ophezulu, ishishini livule ngempumelelo iimarike zabathengi bemizi-mveliso ephezulu, kwaye ubungakanani beshishini lalo buqhubeka bukhula.
Iziseko zegranite, ngenxa yokuzinza kwazo okugqwesileyo, ubulukhuni obuphezulu kunye nokumelana nokuguguleka, kunye nokwanda okuphantsi kobushushu kunye nokuncitshiswa, zidlala indima engenakutshintshwa ekuphuculeni amandla ezixhobo zokugrumba ze-PCB. Ukususela ekufakweni ngokuchanekileyo kunye nokubekwa kwazo ukuya ekuphuculeni ubulukhuni besakhiwo sezixhobo, kunye nokusebenza kwazo okugqwesileyo kwiimeko ezahlukeneyo zemveliso, zonke zibonakalise ngokupheleleyo ixabiso lazo elibalulekileyo ekuphuculeni ukuchaneka kokugrumba kunye nokusebenza kakuhle kwemveliso ye-PCB. Kwindlela yokulandela ukuchaneka okuphezulu kunye nokusebenza kakuhle kwimveliso ye-PCB, isiseko segranite ngokungathandabuzekiyo sisitshixo sokuvula amandla aphezulu ezixhobo zokugrumba ze-PCB, kwaye sifanele ingqalelo ephezulu kunye nokusetyenziswa ngokubanzi kwenani elikhulu lamashishini emveliso ye-elektroniki.
