Yintoni ukwakheka kwe patch resistor| PHILA

Yintoni ukwakhiwa kwe-chip resistors? Namhlanje, umenzi we- inductor manufacturer kukuchazela.

Izinto ezisisiseko

Idatha ye-substrate ye-resistors ye-chip ithathwe kwi-96% ye-al2O3 ye-ceramics. Ukongeza kwi-insulation efanelekileyo yombane, i-substrate kufuneka ibe ne-conductivity egqwesileyo ye-thermal kwiqondo lokushisa eliphezulu. I-motor ineempawu zamandla omatshini kunye nokunye. Ukongeza, i-substrate iyadingeka ukuba ibe mcaba kwaye imakishwe ngokuchanekileyo. Umgangatho wokumelana nokukhusela ngokupheleleyo. I-electrode paste iprintwa endaweni.

Ifilimu echasayo

I-resistivity paste ene-resistivity ethile iprintwa kwi-ceramic substrate kwaye emva koko i-sintered. I-Ruthenium dioxide isetyenziswa yodwa kwi-resistance ointment.

Ifilimu yesondlo

Ukuze kugcinwe i-resistor, kubalulekile ukugubungela ifilimu ye-resistor kunye nefilimu yokugcina. Ngakolunye uhlangothi, idlala indima yokugcinwa komatshini, ngakolunye uhlangothi, ukunyuswa okuqhelekileyo kwe-resistor kugwema iphoso elibangelwa ukudibanisa phakathi kokuchasana kunye nomqhubi osondeleyo. Iyakwazi nokuthintela i-electrode ukuba ikhutshwe yisisombululo se-electrotransfer kwinkqubo ecaleni kokudluliselwa kombane, okubangelwa ukuhla komsebenzi wokuchasana. Ifilimu yolondolozo yindawo ephantsi yokunyibilika yeglasi intlama eprintiweyo kwaye ifakwe i-sintered. I-Chip resistor co., Ltd.

I-Electrode

Ukuze kuqinisekiswe ubukho be-solderability elungileyo kunye nokuqina kwe-resistor, isakhiwo se-electrode esinemigangatho emithathu sisetyenziswa ngokwahlukileyo: ingaphakathi. Ngaphakathi. I-electrode yangaphandle. I-electrode yangaphakathi i-electrode yangaphakathi edibaniswe ne-resistor, ngoko ke idatha ye-electrode kufuneka ikhethwe, ifilimu yokumelana ne-contact resistance resistance, ukuhambelana okuqinileyo kunye ne-ceramic substrate, ukuchasana kweekhemikhali okulungileyo kunye nokusebenza lula kwe-electroplating. Ezinye ziprintwa kwaye zifakwe nge-silver-palladium alloy. Umaleko we-electrode osecaleni ngumaleko we-nickel-plated, owaziwa ngokuba ngumaleko wesithintelo samaza. Umsebenzi wayo kukuphucula ukuxhathisa ubushushu be-welding kunye nokukhusela ukothuka kwe-thermal ye-welding. Kwakhona kunokuphepha ukufuduka kweeyoni zesilivere ukuya kumaleko wefilimu yokumelana kunye nokuthintela umaleko we-tin-lead we-electrode yangaphandle (ekwaziwa ngokuba yi-solderable layer) ekugqweseni i-electrode yangaphakathi. Umsebenzi wayo kukwenza i-electrode ibe ne-weldability elungileyo kwaye yandise ubomi bokugcina be-electrode. Ezinye zifakwe i-electroplated nge-tin-lead alloy.

Ngokwedatha yokuchasa, i-resistors patch rectangular yahlulwe yaba zii-resistors zefilimu ezibhityileyo kunye nezichasi zefilimu ezishinyeneyo. Ipatch inductor le patch inductor ikwabizwa ngokuba yi-inductor yamandla kunye ne-inductor yangoku ephezulu. I-Chip inductor luphawu lwelophu evaliweyo. Ukuchaneka kokumelana nefilimu encinci kuphezulu kwaye i-coefficient yokushisa iphantsi. Ukuqina kulungile, kodwa uluhlu loxhathiso lumxinwa, ngoko lufanelekile kwifrikhwensi ephezulu. Izixhasi zefilimu ezishinyeneyo zihlala zisetyenziswa kwiisekethe.

Oku ngasentla kukuqaliswa kokubunjwa kwe-chip resistors. Ukuba ufuna ukwazi ngakumbi malunga ne-inductors, nceda uzive ukhululekile ukuqhagamshelana nathi.
