Kwimeko yomthwalo ophezulu okanye umsebenzi ohamba ngesantya esiphezulu, ngaba iPCB yokomba kunye nomatshini wokusila i-granite iza kubonakala uxinzelelo lwe-thermal okanye ukudinwa kwe-thermal?

PCB yokomba kunye noomatshini bokusila zisetyenziswa ngokubanzi kushishino elektroniki. Enye yezona zinto zisetyenziswa ngokuqhelekileyo kumacandelo omatshini yigranite. I-Granite yinto enzima kunye neyomeleleyo enokumelana nemithwalo ephezulu kwaye isebenze ngesantya esiphezulu.

Nangona kunjalo, ezinye iinkxalabo ziye zaphakanyiswa malunga nokuba nokwenzeka koxinzelelo lwe-thermal okanye ukudinwa kwe-thermal okwenzeka kumacandelo e-granite ye-PCB yokugaya kunye nomatshini wokugaya ngexesha lomthwalo ophezulu okanye ukusebenza ngesantya esiphezulu.

Uxinzelelo lwe-thermal lwenzeka xa kukho umehluko kwiqondo lokushisa phakathi kweendawo ezahlukeneyo zezinto. Inokubangela ukuba izinto eziphathekayo zande okanye zekhontrakthi, ezikhokelela kwi-deformation okanye i-crack. Ukudinwa kwe-Thermal kwenzeka xa imathiriyeli idlula kwimijikelo ephindaphindiweyo yokufudumeza kunye nokupholisa, ibangela ukuba ibe buthathaka kwaye ekugqibeleni isilele.

Ngaphandle kwezi nkxalabo, akunakwenzeka ukuba amacandelo e-granite e-PCB yokomba kunye nomatshini wokugaya aya kufumana uxinzelelo lwe-thermal okanye ukudinwa kwe-thermal ngexesha lokusebenza okuqhelekileyo. I-Granite yinto yendalo esetyenzisiweyo iminyaka emininzi yokwakha kunye nobunjineli, kwaye ibonakalise ukuba yinto ethembekileyo kunye neyomelele.

Ngaphezu koko, ukuyila komatshini kuthathela ingqalelo amandla oxinzelelo lwe-thermal okanye ukukhathala kwe-thermal. Ngokomzekelo, amacandelo ahlala egqunywe ngoluhlu olukhuselayo lokunciphisa impembelelo yokutshintsha kweqondo lokushisa. Umatshini ukwaneenkqubo zokupholisa ezakhelwe ngaphakathi ukulawula ubushushu kunye nokuthintela ukufudumeza.

Ukuqukumbela, ukusetyenziswa kwegranite kumacandelo e-PCB yokomba kunye noomatshini bokugaya lukhetho oluqinisekisiweyo noluthembekileyo. Nangona iinkxalabo ziphakanyisiwe malunga nokuba noxinzelelo lwe-thermal okanye ukukhathala kwe-thermal, ukuyila komatshini kuthathela ingqalelo le miba kwaye kubangele ukuba kungenzeki ukuba kwenzeke. Ukusetyenziswa kwegranite kwi-PCB yokomba kunye noomatshini bokungqusha lukhetho olukhuselekileyo nolusebenzayo kushishino lombane.
