- Yenza ukuqondiswa kubonakale ekukhiqizweni. Ukusethwa kwesiphakeli, izindlela ze-AOI kanye namarekhodi esihloko sokuqala kufanele kubhekisele encazelweni efanayo ye-axis esetshenziswa yi-firmware kanye nokulinganiswa.
I-Highleap Electronics ingahlanganisa ukuhlanganiswa kwe-PCB yenzwa nokubuyekezwa okuqondiwe kwezinkinga ezivamile ze-PCB DFM , ingeze ukuhlolwa kwekhampasi okuqondene nama-axis enzwa, ukugcinwa kwamagnetic, izingxenye eziseduze ezivunyiwe kanye nokuqondiswa kwesihloko sokuqala ngaphambi kokuba ukwakhiwa kuqhubekele ekukhiqizweni okuphindaphindiwe.
Yenza Ukulinganisa kanye Nokuhlola Isihloko Kulungele Ukukhiqizwa
Ukulinganisa i-Compass, Ukuhlolwa Kokusebenza kanye Nokulandelela
Ukuhlolwa kokukhiqiza kufanele kulandele ukulandelana okukhishwe esikhundleni sokuzama ukuphinda inqubo yokuthuthukisa yonke iyunithi. Ukugeleza okusebenzayo kungaqinisekisa ukuxhumana kwedijithali kanye nempendulo ye-raw axis, kusebenzise inqubo yokulinganisa echazwe ngamakhasimende, bese kuqinisekiswa umphumela wesihloko ezindaweni ezaziwayo. Imikhiqizo ekhokhelwa yi-Tilt ingangeza izikhundla ezimele ze-pitch kanye ne-roll lapho kudingeka khona.
Ukuhlolwa kwesihloko okunenjongo kakhulu kuvame ukwenziwa esimweni sokugcina somshini ngoba indawo ebiyelwe, ibhethri, isipikha, izintambo kanye nensimbi eseduze kungashintsha insimu kazibuthe. Uma imisakazo, izibonisi, izibani zangemuva noma eminye imithwalo yamandla aphezulu ingase idale ukuphazamiseka, ukuhlolwa okuvunyiwe kufanele kufake lezo zimo zokusebenza kunokuhlola ikhampasi ebhentshini elingasebenzi kuphela.
- Chaza ireferensi eyodwa yokukhiqiza. I-OEM kufanele icacise insimu ye-fixture noma ireferensi, ukulandelana kokujikeleza, inguqulo ye-firmware, izimo zokuthambekela kanye nemikhawulo yokuphasa/yokwehluleka.
- Gcina idatha yokulinganisa ilandeleka. Ama-coefficients ngeyunithi ngayinye, izinombolo zochungechunge kanye nezinhlobo ezihleliwe kufanele zihlale zihambisana phakathi kohlelo kanye nokuhlolwa.
- Lawula indawo yokuhlola. Izinto zokwakha, izakhiwo zensimbi eziseduze, imishini kagesi kanye nomzila wekhebula kufanele kugcinwe kufana ukuze kugwenywe ukwehluleka kwekhanda okungelona iqiniso.
I-Highleap ingasebenzisa indlela yokulinganisa ekhishwe yikhasimende kanye nendlela yokuhlola ukusebenza lapho i-fixture kanye ne-acceptance criteria zifanelekela ukukhiqizwa. Uma inqubo isizinzile ekwakhiweni kwe-prototype kanye ne-pilot, uhlelo oluvunyiwe, ukuhlolwa kanye nokugeleza kokuhlola kungadluliselwa ekuhlanganisweni kwe-PCB okunomthamo omkhulu ngaphandle kokuchaza kabusha indlela yokwamukela kusuka ku-batch kuya ku-batch.
Akudingeki iphakheji ephelele yokukhiqiza ukuze kuqalwe isibuyekezo. Amafayela e-PCB atholakalayo, i-BOM, ulwazi lwe-sensor-axis, inani eliqondiwe kanye nokulinganisa okusalungiswa noma inqubo yokuhlola okusebenzayo kwanele ukuthi i-Highleap Electronics ikwazi ukubona ukuhlanganiswa okulandelayo, i-DFM kanye nezidingo zokuhlola.
I-Millimeter Yokugcina Ingashintsha Isihloko
Ngaphambi kokukhiqizwa kwevolumu, i-OEM kufanele imise ukuqondiswa kwenzwa, izibikezelo zokugcina ngaphandle kukazibuthe, izikhundla zebhethri nezipikha, izinto zokubopha, imizila yekhebula, inguqulo ye-firmware/yokulinganisa kanye nendlela yokushintshanisa noma yokujikeleza esetshenziswa ukwahlulela ukusebenza kwekhanda. Le mininingwane kulula ukuyikhohlwa ngoba eminingi iwumshini kunokuba ibe yimidwebo.
I-Highleap ingasebenzisa ama-PCBA e-prototype ukuqinisekisa ukuqondiswa komhlangano, ukunemba kokubekwa kanye nokuhamba komsebenzi wokulinganisa okukhishwe, bese ithwala lezo zilawuli ekukhiqizweni kweqembu. Uma ingxenye ethatha indawo, ingxenye ebiyelwe noma ikhebula kushintsha insimu yendawo, impendulo efanele ukubuyekezwa kobunjiniyela—hhayi ukucabanga ukuthi i-magnetometer “izoyilinganisa.”
Kukhampasi kagesi, i-millimeter yokunyakaza ingabaluleka kakhulu kunomunye umugqa wokumaketha mayelana nekhwalithi ye-PCB. Umsebenzi wefektri ukugcina i-geometry evunyiwe, izinto zokwakha kanye nenqubo kuzinzile ngokwanele ukuze imodeli yokulinganisa yekhasimende iqhubeke nokuchaza umkhiqizo othunyelwayo ngempela.
