Igumbi lovavanyo lokwaluphala olukhawulezileyo lwe-LT-HAST-250 HAST Umfanekiso obonisiweyo

Igumbi lovavanyo lokwaluphala elikhawulezileyo le-LT-HAST-250 HAST

Inkcazo emfutshane:

Igumbi le-HAST (Highly Accelerated Stress Test) lisebenzisa indawo yomphunga engagcwaliyo ukuze lenze uvavanyo olukhawulezileyo lokwaluphala kunye nolwe-hermetic kwiinxalenye ze-elektroniki, ukupakishwa kwe-semiconductor, kunye nee-PCB. Injongo yalo kukufumanisa ngokukhawuleza iziphene ezifihlakeleyo, okunciphisa kakhulu uphuhliso lwemveliso kunye nemijikelo yokuqinisekisa umgangatho.

Iithegi zeMveliso

Ulwakhiwo lwemveliso
1	Igumbi lovavanyo lenziwe ngebhokisi yokukhusela (isakhiwo sokuthwala uxinzelelo) ngaphambili, iyunithi yokukhenkceza kunye neyokuphola ngasemva kunye nomlawuli wombane (inkqubo) esangweni legumbi lovavanyo.
2	Iphaneli yokulawula yombane ibekwe emnyango wangaphambili webhokisi yovavanyo ukuze kube lula ukuyisebenzisa.
3	Iyunithi yefriji kunye neyunithi ye-vacuum kufuneka zibekwe kwibhokisi ezimeleyo ukunciphisa impembelelo yokungcangcazela kunye nengxolo ngexesha lokusebenza kweyunithi yefriji kwibhokisi yovavanyo kunye nokwenza kube lula ukufakelwa nokugcinwa kwezixhobo.
4	Ukuze kuncitshiswe ingxolo eveliswa ngexesha lokusebenza kweyunithi yokufudumeza ifriji, kufakelwa izixhobo ezikhethekileyo zokufunxa isandi sesiponji zokufunxa isandi kunye nokuthintela isandi eludongeni olungaphakathi lwekhreyithi. Amanyathelo okulwa nokungcangcazela kunye nokunciphisa ingxolo athathwa kwiindawo eziphambili ezihambayo.
