Kugadzira PCB yeVideo Wall Controller yeMasisitimu Ekugadzirisa Mavhidhiyo Akawanda

PCB yemuchina wekugadzirisa mavhidhiyo inogamuchira vhidhiyo imwe chete kana kupfuura, inoiyera uye inoibvisa, uye inofambisa mabudiro akawanda ekuratidzira akabatana ayo pamwe chete anoumba kanivhasi hombe yekuona. Kugadzirisa mabudiro akawanda kunoita kuti pave nezvinodiwa zvakawanda paFPGA/SoC bandwidth, DDR frame buffers, HDMI kana mamwe ma display interfaces, kuenderana kwewachi, kutonga kwekupisa uye density yeconnector. Saka kugadzirwa kunoda zvese kudzora kwehardware nekukurumidza uye chirongwa chekuedza mabudiro akawanda.

Highleap Electronics inogadzira uye inounganidza maPCBA ekugadzirisa mavhidhiyo akagadzirwa nevatengi. Isu tinotsigira kugadzirwa kwe multilayer/HDI, BGA FPGA/SoC assembly, DDR memory, HDMI input/output circuits, component sourcing, programming, inspection uye multi-defined customer-defined multi-display functional testing.

1. Zvinhu Zvinokosheswa Pakugadzira PCB neKugadzira Mavhidhiyo Makuru

Zvigadzirwa zvemadziro evhidhiyo zvinofanirwa kugadzirwa kubva pamutoro wepamusoro wekupinda/kubuda panguva imwe chete. Iyo central processor uye dhizaini yekurangarira zvinofanirwa kuchengetedza ma stream ese ukuwo PCB ichichengetedza ma interfaces ekumhanya kwepamusoro kune yega yega connector yekunze.

• Magadzirirwo ekugadzirisa ma "multi-stream": Sarudzo yeFPGA/SoC inofanira kuenderana nehuwandu hwezvinoiswa, huwandu hwezvinobuda, zvinodiwa pakuyera/kucheka uye huwandu hwemapikiseli ese. FPGA Kufunga nezvekubatanidzwa kunova kwakakosha kana chigadzirwa chikashandisa zvishandiso zvikuru zvinogona kurongwa.
• DDR frame-buffer bandwidth: Ma "active display" akawanda anogona kuda ma "frame buffers" akawanda uye "high memory bandwidth". Marongerwo acho anofanira kutevedzera. high-speed PCB dhizaini mitemo yeDDR topology uye kusimba kwesimba.
• Nzira dzekupinda/kubuda dzeHDMI: Chiteshi chega chega cheHDMI chinoda nzira inodzorwa, divi rekubata uye geometry yekubatanidza zvinoenderana ne PCB yeHDMI interface.
• Kubvumirana: Nguva yekubuda, kuenderana kwemafuremu uye kugoverwa kwewachi zvinofanirwa kutsanangurwa kuitira kuti mataira asabvaruke kana kudonha kana kudonha zvichienderana neumwe neumwe.
• Power delivery: Midziyo mikuru yeFPGA/SoC inogona kuda marails akawanda ane voltage shoma ane current current yakakwira. Kutevedzana kwerail uye kugona kwayo kushanda kunofanirwa kusimbiswa pasi pema active streams akawanda.
• Dhizaini yekupisa: Purosesa, DDR nezvimwe zvishandiso zvakawanda zveHDMI zvinogona kugadzira kupisa kwakasimba. Hurongwa hwekutonhodza hunoburitswa hunofanira kuongororwa kuti hushande zvakanaka. Maitiro ekutarisira kupisa kwePCBMhangura, zvinopisa, mhepo inoyerera uye fungidziro dzefeni dzinovharirwa dzinofanira kunge dziri chikamu chekugadzirwa kwesystem yakaburitswa.

Sei muchina wekutonga madziro evhidhiyo uchigona kuda HDI kunyangwe PCB yakakura panyama?

Pakeji yepakati yeFPGA/SoC inogona kunge iine BGA yakanaka ine mazana kana zviuru zvekubatanidza. Kufambisa ma "escape routing", kuburitsa magetsi uye memory inomhanyisa zvinogona kuda ma "microvia" kunyangwe kana saizi yebhodhi rekunze yakakura.

Chii chinonyanya kukosha pakugadzira kunze kwemafaira ePCB?

Magadzirirwo chaiwo ekuisa/kuburitsa. Bhodhi rinoedzwa nekuisa kamwe chete uye kubuda kumwe chete rinogona kusaratidza matambudziko eDDR bandwidth, simba kana kupisa anoitika kana zvese zvinobuda pamadziro zvichishanda.

2. Kuyera, Kucheka, Kubatanidza Furemu uye Kubatanidzwa kweMulti-Output HDMI

Chinodzora madziro evhidhiyo chinobatanidza mabasa ekuyera nehurongwa hwema "multi-output routing". Iyo firmware yekugadzirisa inosarudza kuti chikamu chipi chechinhu chinoonekwa pane imwe neimwe display uye kuti nguva inowiriraniswa sei.

• Pombi yekuyera/yekucheka: Tsanangura magadzirirwo ecanvas, giraidhi yemataira, muripo webezel uye resolution yemuchina wekuyedza wefekitori.
• Zvibatiso zvefuremu: Midziyo yeDDR inofanira kuramba iri pedyo ne processor uye kushandisa topology yekurangarira yakaburitswa kutsigira kuverenga/kunyora panguva imwe chete.
• Kugoverwa kwewachi: Nguva yekubuda kwemagetsi inobatwa nejitter inofanira kushandisa dhizaini yewachi yakanyorwa ine simba rekusefa rinodzorwa.
• Kudzokorora kweHDMI: Nzira yega yega yekutumira data inofanira kuzadzisa bhajeti rekubatanidza chigadzirwa uye mutemo weEDID/HPD. Zvinonetsa nezvekufambisa data nekukurumidza mu HDMI PCB kugadzirwa kunoshanda kune ese mataira anobuda.
• OSD/network yekudzora: Ethernet/USB/serial control, presets uye EDID tables mabasa anodzorwa nefirmware anofanira kuramba akabatana nekuvandudzwa kwehardware.

Masisitimu emadziro evhidhiyo ekutengeserana anogona kutsigira marongero akasiyana-siyana uye mafomati enzvimbo. Kuedza kugadzira kunofanirwa kushandisa seti shoma asi yakarongwa yemapatani inoratidza port mapping, tile geometry uye kushanda panguva imwe chete pasina kuedza kutevedzera chirongwa chose chekusimbisa application software.

3. BGA/HDI Assembly, Connector Arrays uye Kuongorora

MaPCBA ekugadzirisa madziro evhidhiyo anowanzova nemapurosesa makuru rimwe chete kana anopfuura, mapakeji akawanda eDDR uye akawanda maHDMI connectors. Anogona kuongororwa nehurongwa hwekutanga usati wagadzira zvese zvekutanga.

• Kuungana kweHDI/BGA: Highleap inogona kusanganiswa HDI PCB kugadzira neBGA assembly apo pasuru yakaburitswa uye stack-up inoda sequentially lamination.
• Component sourcing: Ma-transceiver eFPGA/SoC, DDR, HDMI, mawachi uye maPMIC anofanirwa kutevedzera zvinotenderwa nevatengi. chikamu chekutsvaga list.
• AOI: AOI muPCBA inoongorora mabhangi ekubatanidza, mapassives uye majoini anooneka.
• X-ray: X-ray kuongorora inogona kushandiswa pamapakeji makuru eBGA uye magumo akavanzwa apo hurongwa hwemhando hunoda izvozvo.
• Madhata ekubatanidza emakanika: Mapaneru ane maport akawanda anofanira kugovana data reference nePCB kudzivirira kusawirirana kwe connector.

Sei mapurogiramu eFPGA achifanira kudzorwa sechikamu chekuburitswa kwemusangano?

Bhodhi remadziro evhidhiyo rinogona kunge rakarurama pamagetsi asi risingashandiswe kana paine bitstream kana memory configuration isiriyo. Saka, mufananidzo weFPGA, MCU firmware, matafura eEDID uye PCB/BOM revisions zvinofanira kuburitswa pamwe chete.

4. Kuedza Kunoshanda Kwezviratidziro Zvakawanda uye Kusimbiswa Kwekupisa Kwakazara

Kuedzwa kwekugadzira kunofanirwa kuratidza hunhu hwechiteshi uye kugadziriswa panguva imwe chete. OEM inofanira kutsanangura magadzirirwo emadziro anomiririra iyo inosimbisa processor uye system yemagetsi.

• Kuonekwa kwezviri kuiswa: Simbisai chinhu chimwe nechimwe chinotsigirwa uye modhi yevhidhiyo yakasarudzwa.
• Mepu yekubuda: Simbisa kuti chinongedzo chega chega chinobuda chinoenderana netiya/chiteshi chakakodzera.
• Magadzirirwo emufananidzo: Shandisa grid, crosshatch kana pattern ine manhamba kuti uone kukura, kuchekwa uye kurongeka.
• Kushanda kwemutoro wakazara: Shandisa huwandu hwakatarwa hwezvinobuda kwenguva yakareba zvakakwana kuti uongorore kugadzikana kwesimba uye tembiricha.
• FCT yefekitori: Highleap inogona kuita kushanda kushanda uchishandisa mapatani esource akatenderwa, setup ye display/analyzer, firmware uye miganhu yekupasa/kukundikana.

5. Kuburitswa kweZvigadzirwa uye RFQ Data yeVideo Wall Controller Kugadzira PCB

Mashoko ekugadzirisa madziro evhidhiyo anofanira kusanganisira kuomarara kwema processor, ndangariro, huwandu hwema ports uye test coverage nekuti izvi zvinosarudza stack-up, BGA process, connector labor uye functional-test time.

• Pakeji yePCB: Stack-up, HDI/via definition, impedance, board thin uye thermal/mechanical data.
• Purosesa/ndangariro: FPGA/SoC, DDR, flash uye zvishandiso zvekugadzirisa zvine maMPN chaiwo.

• Kuronga: FPGA bitstream, MCU firmware, presets uye revision control.
• FCT: Mepu yemataira, mapatani ekwakabva, mamiriro ekutakura zvinhu zvakakwana, zvinodiwa pakupisa uye matanda akachengetedzwa.

Rondedzero yeRFQ yekugadzirwa

• Mafaira ekugadzira PCB akaburitswa uye HDI/stack-up notes
• FPGA/SoC uye DDR BOM
• Mepu yechiteshi chekupinda/kubuda uye zvinodiwa zveHDMI
• Zvinoreva zvemagetsi zvekupisa/heatsink/feni
• Firmware/bitstream/configuration package
• Chirongwa chekuedza mashandiro ezviratidziro zvakawanda
• Muenzaniso, chiyero chekutanga kana huwandu hunodzokororwa
• Zvinodiwa pakurongedza uye kutevedza zvinodiwa

Highleap Electronics inotsigira kugadzirwa kwePCB uye kuunganidzwa kwevashandisi vemavhidhiyo nevanotonga vakagadzirwa nevatengi. Kugadziriswa kwemadziro akaiswa, kubatanidzwa kwezviri mukati-system uye kutevedzera zvizere zvigadzirwa zvinoramba zviri muOEM kunze kwekunge zvabvumiranwa zvakasiyana.
