Michina yekuboora nekugaya maPCB inoshandiswa zvakanyanya muindasitiri yekugadzira maelektroni. Yakagadzirirwa kuboora nekugaya mabhodhi edunhu akadhindwa (PCBs) nemazvo uye nekumhanya kwakanyanya. Zvisinei, michina iyi inogona kugadzira electromagnetic interference (EMI) panguva yekushanda kwayo, izvo zvinogona kukanganisa mashandiro emidziyo yemagetsi iri pedyo. Kuti vaderedze dambudziko iri, vagadziri vazhinji vari kuisa zvikamu zvegranite mumichina yavo yekuboora nekugaya maPCB.
Granite chinhu chinogadzirwa zvakasikwa, chine huwandu hwakawanda uye chine hunhu hwakanaka hwekudzivirira magiya emagetsi. Inowanzoshandiswa mukuvaka masisitimu epamusoro-soro eaudiophile speaker uye michina yeMRI. Hunhu hwegranite hunoita kuti ive yakakodzera kushandiswa mukuvaka michina yePCB yekuboora nekugaya. Kana ikaiswa mumichina iyi, zvikamu zvegranite zvinogona kuderedza zvakanyanya EMI nemhedzisiro yayo pamidziyo yemagetsi iri pedyo.
EMI inoitika kana minda yemagetsi inogadzirwa nemidziyo yemagetsi. Minda iyi inogona kukonzera kukanganiswa kwemimwe midziyo yemagetsi, zvichikonzera kusashanda zvakanaka kana kukundikana. Nekuwedzera kuoma kwemasisitimu emagetsi, kudiwa kwekudzivirira kweEMI kunoshanda kuri kuramba kuchikosha. Kushandiswa kwezvikamu zvegranite mumichina yekuchera nekugaya yePCB kunogona kupa dziviriro iyi.
Granite inodzivirira magetsi zvakanaka uye haifambise magetsi. Kana EMI ikagadzirwa mumuchina wekuboorera nekugaya wePCB, inogona kunyudzwa nezvikamu zvegranite. Simba rinonyudzwa rinozobviswa muchimiro chekupisa, zvichideredza huwandu hweEMI. Chinhu ichi chakakosha mukugadzirwa kwePCB nekuti huwandu hwakawanda hweEMI hunogona kukonzera mapuranga asina kunaka. Kushandiswa kwezvikamu zvegranite mumichina yekuboorera nekugaya yePCB kunogona kuderedza njodzi yemapuranga asina kunaka nekuda kweEMI.
Uyezve, granite yakasimba zvikuru uye haiparare kana kubvaruka. Ine mwero wakaderera wekuwedzera kwekupisa, zvinoreva kuti inogona kutsungirira tembiricha yakanyanya isina kutsemuka kana kupwanyika. Izvi zvinoita kuti zvikamu zvegranite zvive zvakanaka kushandiswa munzvimbo dzakaoma dzekushanda dzePCB drilling uye milling machines. Kugara kwenguva refu kwezvikamu zvegranite kunoita kuti muchina ushande zvakanaka kwemakore, zvichideredza mari yekugadzirisa uye nguva yekushanda.
Mukupedzisa, kushandiswa kwezvikamu zvegranite mumichina yekuchera nekugaya yePCB inzira inoshanda yekuderedza mazinga eEMI uye njodzi yemabhodhi asina kunaka. Hunhu hwekudzivirira hwegranite hunoita kuti ive chinhu chakanakira kushandiswa mukuvaka michina iyi. Kugara kwenguva refu uye kuramba kubvaruka kunoita kuti zvikamu zvegranite zvive sarudzo yakakwana yenzvimbo dzakaoma dzekushanda dzemichina yekuchera nekugaya yePCB. Vagadziri vanoisa zvikamu zvegranite mumichina yavo vanogona kuve nechokwadi chekuti vatengi vavo vanogamuchira michina yakasimba uye yakavimbika inoshanda nemazvo.
