Iiparamitha ezininzi zonxibelelwano ezibalulekileyo ezinje nge-impedance, attenuation, ulibaziseko kunye ne-close-end crosstalk attenuation ye-SAS transmission line ihlalutywa, kwaye amanqaku aphambili oyilo lwenkqubo yokwenziwa kunye nolawulo lwenkqubo ayacaciswa. Izinto ezinokubangela ukuba ezi parameters zibaluleke ngasentla ziwohloke kwinkqubo nganye zilawulwa.
Kwinkqubo yemveliso yenkqubo yokugquma, ukuqwalaselwa okubanzi kwezinto ezichaphazela umgangatho wemveliso, uhlalutyo lwethiyori kunye nezixhobo ezithile kunye nokusetyenziswa kwangempela kwezinto eziluhlaza, kwaye ekugqibeleni wenze isicwangciso senkqubo efanelekileyo yokukhokela ukuveliswa kwe-SAS. inkqubo yokugquma umgca wesantya esiphezulu. Ngenxa yokuba izinto ezikrwada kunye nezixhobo zokuvelisa ezikhethwe lishishini ngalinye lemveliso zahlukile, kukho umahluko othile kwizicelo ezisebenzayo. Kukho izinto ezininzi ezichaphazela iiparameters zokusebenza kwe-insulation ye-foam ebonakalayo, kodwa izinto eziphambili ezichaphazelayo ngamanqaku akhankanywe kweli phepha. Kwinkqubo yokuvelisa, izinto eziphambili zinokusombululwa kuqala, kwaye emva koko izinto ezizisekondari zilungelelaniswe.
Iimfuno zezixhobo
Kwinkqubo yokuvelisa le mveliso, kuyimfuneko ukuqonda amagama amabini abalulekileyo, i-1, ukugubungela, i-2, i-hot melt.
Ubukhulu kunye nesantya sokugqithelana kwefoyile yealuminiyam esongelweyo kufuneka ilawulwe ngokungqongqo, kwaye ireyithi yokugqithelana yocingo oluqhelekileyo inokuhlangabezana neemfuno kwi-15-25%, kodwa i-SAS isebenzisa ubume bemibini yemigca enxuseneyo, kunye nobuchule bokuchasana ne-anti-crosstalk. izibini zomgca ngokwazo zincitshiswe kwi-zero. Ukuqinisekisa ukuba i-crosstalk attenuation yesiphelo esikufuphi sentambo, ngokuqhelekileyo kufuneka ukuba izinga lokugoqa liphakathi kwe-30-40%, inkqubo yokulawula inkqubo yokuvelisa ukusonga kubaluleke kakhulu, umgangatho wokusonga uya kuchaphazela. ukungafani komgangatho wokuhambisa, njengokukhutshwa kwefoyile ye-aluminium ayigudi kwaye kukho iitshiphusi ze-aluminium, xa ukuvaleka ukuya kwinqanaba eliqhelekileyo, ifoyile ye-aluminium iya kutsalwa. cima Ukongeza, ukuba ifoyile ye-aluminiyam ayibekwanga ngokutyibilikayo, inkunkuma iya kukhutshelwa, kwaye iya kubambelela kumphezulu wocingo olungundoqo olungalinganiyo kakhulu, oluchaphazela ukufana kwendlela yothumelo, okukhokelela ekunciphiseni kokwenziwa komsebenzi wothumelo. imveliso, ngakumbi i-impedance kunye nokunciphisa.
Ngaphambi kokuba isibini esahlukileyo sithathe, iteyiphu ye-polyester yokuzimela kufuneka ifudunyezwe ukuze i-adhesive eshushu inyibilike ye-self-adhesive polyester tape inyibilike kwaye ibophe. Indawo eshushu yokunyibilika ithatha iqondo lobushushu elilawulwayo lokufudumeza i-electromagnetic preheater, kwaye ubushushu bobushushu bunokulungiswa ngokufanelekileyo ngokweemfuno zokwenyani. Iindlela zokufakela i-preheater ngokubanzi zithe nkqo kwaye zithe tyaba ezimbini, i-preheater ethe nkqo inokugcina indawo, kodwa isibini esijikajikayo kufuneka sidlule kwi-Angle enkulu yevili lesikhokelo, ukuze ungene kwindawo yokufudumeza, kulula ukwenza i-insulation core kunye nendawo ehambelanayo. yokutshintsha kweteyiphu yokusonga, okukhokelela ekunciphiseni ukusebenza kombane kumgca wokuhanjiswa kwesantya esiphezulu. Ngokwahlukileyo, ngenxa yokuba i-preheater ethe tye ikumgca othe tye kunye nesibini esijikelezayo, ngaphambi kokungena kwi-preheater, iperi yocingo idlula kuphela amavili ambalwa esikhokelo kunye nomsebenzi wokulungisa wesizwe, kunye ne-Angle yokunitha ucingo olujikelezayo alutshintshi xa ukudlula kwivili lesikhokelo, eliqinisekisa i
ukuzinza kwesigaba sokunitha isikhundla socingo olugqunyiweyo kunye netape yokujija. Okukuphela kokungalunganga kwe-preheater ethe tyaba kukuba ithatha indawo eninzi kwaye umgca wemveliso mkhulu kunomatshini wokujija oxhotyiswe nge-preheater ethe nkqo.
Ngoko ke, xa ukhetha izixhobo, kuyimfuneko ukuqwalasela ngokupheleleyo umthamo wezixhobo kunye nemeko yangempela yeworkshop yokuvelisa. Ngokuqhelekileyo, ukuba iimeko zesithuba seworkshop yemveliso zivumela, ii-preheaters ezithe nkqo zingasetyenziselwa imigca yonxibelelwano ye-high-frequency engaphantsi kwe-5GHZz, ngelixa ii-preheaters ezithe tye zisetyenziselwa imigca yonxibelelwano ye-frequency ephezulu kunye ne-frequencies ephezulu. Ukuba indawo yeworkshop yemveliso ilinganiselwe, ukuveliswa kwemigca yokuhambisa rhoqo ngaphezulu kwe-5GHz kunokusebenzisa izifudumezi ezithe nkqo, kodwa xa kuthelekiswa nezifudumezi ezithe tye, ulawulo lwenkqubo lunzima ngakumbi. Xa usonga i-polyester tape, kufuneka kuqatshelwe ukuba isalathiso sokusonga kufuneka sichasane nesalathiso se-aluminium foil, izinga lokugqithana lizinzile, kwaye akukho nto ingathandekiyo efana ne-warping. Ngaphambi kokufumana, kuyimfuneko ukufudumeza iteyiphu ye-polyester yokunamathela, ubushushu bokufudumala akufanele buphakame kakhulu, ubushushu buphantsi kakhulu, i-adhesive eshushu enyibilikayo ayinakunyibilika ngokupheleleyo, ibhondi ayinamandla, kwaye kulula. ukuba ne-adhesion yokuvuza, efana nokuvuza kwe-adhesion phenomenon, imveliso ayinakufunyanwa ingafanelekanga kwinqanaba lokuqala lovavanyo, kodwa emva kokuhamba kwinkqubo yokusetyenziswa kamva, kunokwenzeka ukuba kubangele. ideformation ekhululekileyo yokusonga. Ukukhokelela kwi-polyester ehlawuliswayo umaleko we-aluminium foil inento yokuvula, ekhokelela ekuvuzeni kwamaza e-electromagnetic, okuchaphazela isiphumo sokhuselo, okukhokelela kwinkunkuma yemveliso, kwaye nje ukuba oku kungafanelanga kwenzeke kwinkqubo yokusetyenziswa, kuya kubangela ilahleko enkulu. Ukuba iqondo lobushushu liphezulu kakhulu, kulula ukubangela ukuba undoqo wokugquma uthambe kwaye ukhubazeke, kwaye ukhokelele ekuncamatheleni kocingo olungundoqo, okukhokelela kwiimveliso ezingafanelekanga, ngoko ke ubushushu bokufudumala kufuneka bulawuleke ngokungqongqo. Ngokwale nkcazo ingentla, akukho nzima ukubona ukuba isantya sokuvala sikwabalulekile, phantsi kobushushu obufanelekileyo bokufudumeza, ukuba isantya sokuvala sikhawuleza kakhulu, siya kuchaphazela ukunyibilika kokuncamathelisa okunyibilikayo, kucotha kakhulu kuya kukhokelela i-softening and deformation of the core wire, iziphumo ziyafana neqondo lokushisa elingafanelekanga, kwaye ukutshatyalaliswa kuya kwanda ngokukhawuleza kwinqanaba elithile.
