Kutarisa kuri nyore kwe "screen turn on" hakuna kusimba nekuti flex yekuratidza inochinja-chinja kana tambo yemagetsi inogona kupfuura kamwe chete yokundikana panguva yekudzokororwa kwekugadzirisa. NPI inogona kuona kuti mangani maitiro ekuvandudza kana shanduko dzemamiriro ezvinhu dzinodiwa kuti ubate zvikanganiso zvekubatanidza pasina kuita kuti bvunzo yemutsetse irebe zvisina kufanira.

Kuyerwa kwazvino kunofanirwa kutsanangurwa kwakwo kwekuyedzwa. Active refresh current, idle current uye deep-sleep current mamiriro akasiyana uye haafanirwe kusanganiswa kuita muganho mumwe chete. Kana mutengi achida kuongororwa kwazvino kwekugadzirwa, kuvakwa kwefirmware, kunonoka kwekuyera uye peripherals dzakabatana zvinofanirwa kugadziriswa. Izvi zvinogadzira gedhi rinodzokororwa rinodzivirira mashandiro asina simba rakawanda uku richidzivirira kutadza kwenhema kunokonzerwa nesoftware isingadzoreki kana chiitiko chekuratidzira.

8. Kutsvaga uye Kusarudza Vatengesi veE-Reader PCB Production

Kuti uwane E-Reader PCB RFQ, sarudza display module, touch/front-light options, battery interface, wireless configuration, performances approved uye test criterials. Izvi zvinodzivirira assembler kuti isashandise ma e-reader SKU maviri akafanana ne e-reader building se electronics building.

mhedziso

Dambudziko guru rekugadzira mu-e-reader nderekuchengetedza sisitimu ine simba shoma yakatenderedza ePaper display. Zvirimo zvakarurama zvinofanirwa kusimbisa maitiro ekumirira, kubatanidzwa kwedisplay-drive, manejimendi yebhatiri uye mabasa ekubata/kumberi-mwenje - kwete kutevedzera template yePCB yepiritsi nekombuta.

Kuwanikwa kwezviratidziro kazhinji ndiko kunonyanya kushandiswa muhurongwa hwekutsvaga e-reader nekuti module, rutsigiro rwemutyairi uye firmware zvakabatana. Usati wabvumidza zvimwe zvinoshandiswa, kutenga kunofanirwa kusimbisa pinout yemagetsi, kukodzera kwemuchina, zvinodiwa zvewaveform/configuration uye kuwanikwa kwenguva refu. Yambiro imwechete inoshanda kune maPMIC, zvishandiso zvisina waya uye zvikamu zvebhatiri/charging. Kutsiva kwezvinhu zvinogona kuve kwakakura chete kana voltage, leakage, temperature coefficient nezvimwe zvinhu zvakakosha zvichiri mukati memiganhu yekugadzira.

Kuti muwane mashoko ekutaura, sarudzai mabasa akagadzirwa uye asiripo nemaune. Isai nhamba dzezvikamu zve display and touch module, sarudzo ye front-light, bhatiri interface, wireless configuration, stack-up, BOM/CPL, mafaira eprogramming uye test limit. Izvi zvinoita kuti Highleap igadzire nzira ine mutengo wekugadzira, kuunganidza uye low-power functional testification. Zvinodzivirirawo chikanganiso chinowanzoitika chekubata ma e-reader SKU maviri akafanana nekuti ane enclosure kana board outline.

Poindi yekushandura yeRFQ

Kuti muwane purojekiti itsva yeE-Reader PCB , tumirai ePaper module specification uye ruzivo rwekubatanidza pamwe chete nePCB package. Highleap inogona kuongorora njodzi yekubatanidza display, low-power assembly controls uye test sequence isati yaitwa prototype lot.
