Substrate na DPC Ceramic: zaɓi mai kyau don marufi na kwakwalwan LiDAR na mota
Aikin LiDAR (Gano Haske da Range) shine fitar da siginar laser ta infrared da kuma kwatanta siginar da aka nuna bayan fuskantar cikas tare da siginar da aka fitar, domin samun bayanai kamar matsayi, nisa, yanayin, gudu, hali, da siffar abin da aka nufa. Wannan fasaha na iya cimma gujewa cikas ko kewayawa kai tsaye. A matsayin firikwensin da ke da daidaito sosai, ana ɗaukar LiDAR a matsayin mabuɗin cimma tuƙi mai ƙarfi, kuma mahimmancinsa yana ƙara bayyana.
Tushen hasken laser sun yi fice a cikin manyan abubuwan da ke cikin LiDAR na mota. A halin yanzu, tushen hasken VCSEL (laser mai fitar da saman rami a tsaye) ya zama zaɓi mafi kyau ga LiDAR mai ƙarfi da walƙiya a cikin motoci saboda ƙarancin farashin kera shi, babban aminci, ƙaramin kusurwar bambance-bambance, da haɗin 2D mai sauƙi. Chip ɗin VCSEL zai iya cimma nisan ganowa mai tsawo, daidaiton fahimta mafi girma, da kuma bin ƙa'idodin tsaro na ido masu tsauri a cikin LiDAR mai ƙarfi na mota. Bugu da ƙari, suna ba Flash LiDAR damar cimma hangen nesa mai sassauƙa da faɗi, kuma suna da fa'idodi masu yawa na farashi.
Abubuwan yumbu sun zama kayan marufi na guntu masu kyau don aikace-aikacen LiDAR na mota.
Abubuwan da aka yi da yumbu na DPC (Direct Copper Plating) suna da ƙarfin watsa zafi mai yawa, babban rufi, daidaiton da'ira mai yawa, santsi mai yawa a saman, da kuma ƙimar faɗaɗa zafi wanda ya dace da guntu. Hakanan suna ba da haɗin kai tsaye don biyan buƙatun marufi na VCSEL.
1. Kyakkyawan watsawar zafi
Tsarin yumbu na DPC yana da haɗin kai tsaye, yana samar da tashoshi masu zaman kansu na ciki. Saboda gaskiyar cewa yumbu suna da masu hana ruwa da masu kula da zafi, suna iya cimma rabuwar thermoelectric da kuma magance matsalar watsa zafi na kwakwalwan VCSEL yadda ya kamata.
2. Babban aminci
Ƙarfin guntun VCSEL yana da yawa sosai, kuma rashin daidaiton faɗaɗa zafi tsakanin guntun da substrate na iya haifar da matsalolin damuwa. Matsakaicin faɗaɗa zafi na substrates na yumbu ya dace sosai da VCSEL. Bugu da ƙari, substrates na yumbu na DPC na iya haɗa firam ɗin ƙarfe da substrates na yumbu don samar da rami mai rufewa, tare da ƙaramin tsari, babu tsaka-tsakin layi na haɗin kai, da kuma matsewar iska mai yawa.
3. Haɗin kai tsaye
Marufi na VCSEL yana buƙatar shigar da ruwan tabarau a saman guntu, don haka ana buƙatar saita ramin 3D a cikin substrate. Substrates na yumbu na DPC suna da fa'idar haɗin kai tsaye tare da babban aminci, waɗanda suka dace da haɗin kai tsaye na eutectic.
A cikin mahallin haɓaka motoci masu hankali, kayan yumbu suna taka muhimmiyar rawa wajen haɓaka sabbin motocin makamashi masu hankali. A matsayin tushen dukkan fasahar, ci gaba da ƙirƙira a fasahar kayan abu yana da mahimmanci don tallafawa ingantaccen ci gaban masana'antar gaba ɗaya.
