Controller firmware/NVM, retimer configuration, PD firmware, EEPROM contents, approved protection devices, connectors uye reference cables zvese zvinogona kukanganisa maitiro. Kudzokorora kuvaka uchishandisa maGerber akafanana asi mafaira akasiyana ekugadzirisa hakusi kuburitswa kwehardware kwakafanana kubva pakushanda. Configuration checksum kana version recording zvinogona kudzivirira iyi class ye hidden variation.
Kuronga hupenyu hwezvikamu kwakakoshawo nekuti ma controllers ane kumhanya kwakanyanya uye zvikamu zve interface zvine hunyanzvi zvinogona kunge zvine zvimwe zvishoma. Pachikamu chimwe nechimwe chakakosha, tsanangura kana kuchinjwa kuchida simulation, test bench, retest compliance kana chete mvumo yekutenga. Kupatsanura uku kwekutanga kunokurumidza kupindura kushomeka pasina kushandura dambudziko rekugovera kuita kuyedza kwemagetsi kusingadzoreki panguva yekugadzira zvinhu zvakawanda.
9. Kusarudza Mubatsiri weThunderbolt Dock PCB Manufacturing
Mupi weThunderbolt Dock PCB anofanira kukwanisa kushandura zvinodiwa zvechiteshi kuita kugadzirwa kwakadzorwa, kuunganidza mapakeji ekutonga akasimba, kugadzirisa mashandiro ekubatanidza USB-C uye kuita matrix yekuyedza inobvumirana nekukurumidza. Bvunza kuti impedance, kudzora zvinhu, kuburikidza nezvivakwa, X-ray, kugadzirisazve uye kutevedza magadzirirwo zvinobatwa sei.
mhedziso
Dambudziko guru rekugadzira madoko eThunderbolt nderekuti magadzirirwo emachiteshi ane kumhanya kwepamusoro uye akawanda-protocol akasimbiswa. Zviri mukati mazvo zvinofanirwa kutaura nezve protocol tunneling, kurasikirwa nemachiteshi, controller/configuration control uye interability—pasina kubata topology imwe chete, zvinhu, retimer strategy kana layer count seyakajairika.
Zvikwaniriso zvemutengesi zvinofanira kuongorora maitiro ekumhanya-mhanya. Bvunza kuti mugadziri anodzora sei kugadzirwa kwe dielectric uye impedance, kuti zvivakwa zvinoongororwa sei kuburikidza nezvivakwa, kuti zvinhu zvinotsiviwa sei zvinotenderwa uye kuti muunganidzi anotarisira sei BGA X-ray, controller programming uye Type-C connector alignment. Mutengesi anofanirawo kukwanisa kutsanangura musiyano uripo pakati pebvunzo yekushanda kwekugadzira uye bvunzo yepamutemo yeThunderbolt/USB4 compliance.
Kuti muwane mutengo, ipai dhizaini yekuvaka/block, gadziriro yeThunderbolt/USB4, zvinodiwa zve stack-up/channel, port matrix, bhajeti yemagetsi, BOM/CPL, mafaira ekugadzirisa uye zvinotarisirwa pakuyedza. Highleap inogona kushandisa kugadzirwa, kuunganidzwa kwezvikamu zvakakosha, kuongororwa uye kusimbiswa kwakatsanangurwa nevatengi maererano nedhizaini chaiyo. Kune Thunderbolt Dock PCB , iyi nhanho yetsananguro yakakosha nekuti "high-speed USB-C dock" haisiyo nhanho yakakwana yekugadzira.
Poindi yekushandura yeRFQ
Tumira dhayagiramu yeblock inomhanyisa uye stack-up yakaburitswa neBOM/configuration package. Highleap inogona kuongorora njodzi yekugadzira ine chekuita nechiteshi, BGA assembly, Type-C mechanics uye practical production test matrix isati yasvika NPI.
