Kugadzira PCB yeHDMI Matrix Switch yeMulti-Input Multi-Output AV Routing

PCB yeHDMI matrix switch inoendesa chero maHDMI inputs akawanda kune chero ma outputs akasiyana-siyana, kazhinji neEDID yakazvimirira, HDCP uye maitiro ekuteerera panzira yega yega. Magadzirirwo acho anokurumidza kukura: matrix ye4×4 kana 8×8 ine ma channels akawanda ane kumhanya kukuru, connector launches, power rails uye firmware states kupfuura simple switch kana splitter. Saka, kugadzirwa kunoenderana nekuenzana kwe channel, crosspoint selection, signal conditioning uye structured test matrix.

Highleap Electronics inogadzira uye inounganidza maPCB nemaPCBA akagadzirwa nevatengi. Isu tinotsigira kugadzirwa kwe multilayer neHDI kana zvichidikanwa, BGA/QFN assembly, connector population, programming, test uye functional testing inotsanangurwa nevatengi.

1. Key HDMI Matrix Switch PCB Design uye Manufacturing Priority

Zvigadzirwa zvematrix zvinofanirwa kurongwa zvichienderana nehuwandu hwezvinobatanidza zve high-bandwidth panguva imwe chete, kwete chete huwandu hwezvinobatanidza. Crosspoint kana HDMI transceiver architecture ndiyo inosarudza kuti bhodhi rinofanira kutsigira mangani machannel, wachi uye control interfaces.

• Tsanangudzo yePort uye bandwidth: Tsanangura saizi yematrix, nzira dzinodiwa panguva imwe chete uye mwero weTMDS/FRL. Marongerwo ekumhanya kwepamusoro anogona kuongororwa uchishandisa PCB yeHDMI interface zvirambidzo zvenzira yega yega yekupinda/kuburitsa.
• Kuwanda kwenzira dzekufambisa mugwagwa: Zvishandiso zveBGA/QFN zvine maport akawanda zvinogona kugadzira nzira yekubuda nayo yakawanda. HDI pcb Zvivakwa zvinofanirwa kushandiswa chete kana kuburikidza ne density uye package pitch zvichizvitsigira.
• Kudzorwa kweimpedance pachiteshi chimwe nechimwe: Nzira yega yega inofanira kusangana nepfungwa dzakafanana dzemagetsi, ichishandisa nzira yekurongedza zvinhu yakatsanangurwa mu PCB inokurumidza kuunganidzwa patani.
• Signal conditioning: Zvishandiso zve "retimers", "redrivers" kana "equalizers" zvinogona kudiwa pa "inputs" kana "outputs" zvichienderana nehurefu hwenzira uye link rate. Zvirongwa zvinofanirwa kunge zviri pasi pe "firmware/BOM control".
• Magadzirirwo emagetsi: Magadzirirwo eHDMI akawanda anogamuchira/anotumira magetsi, FPGA/MCU uye ma signal conditioners anogona kugadzira simba remagetsi nekupisa kwakawanda. Dhizaini yacho inogona kuongororwa zvichienderana ne Maitiro ekutarisira kupisa kwePCB pahuwandu hwepamusoro hwechiteshi chinoshanda. Kutevedzana kwesimba remagetsi uye kupararira kwekupisa zvinofanirwa kuongororwa pahuwandu hwepamusoro hwechiteshi chinoshanda.
• Kudzora nzira yekudzoka neEMI: Nzira dzakawanda dzinomhanya zvakanyanya dzinoita kuti vanhu vataure zvakasiyana-siyana uye vataure zviri kuitika. Nzira dzinofanira kuteverwa nedzinofamba dzinofanira kufamba nenzira dzakasiyana-siyana. high-speed PCB Dzidzirai muchina wese wekubatanidza kubva kune mumwe kuenda kune mumwe. Dzivisai kubatanidza zvinhu zvinomanikidzana kupfuura nepakati penzvimbo dzakakamurwa kana kuti zvakamanikana kuburikidza neminda.

Sei matrix PCB yakaoma kugadzira kupfuura switch ye4-to-1 HDMI?

Matrix ine nzira dzakawanda dzinogamuchira nekutumira dzinoshanda panguva imwe chete, nzira dzakawanda dzinoyambuka nekumhanya, EDID/HDCP dzakawanda uye functional-test coverage yakakura. Bhodhi rinogonawo kuda BGA crosspoint/FPGA uye dhizaini yesimba/thermal yakaoma.

Matrix inofanira kushandisa HDI rini?

HDI inoruramiswa kana central crosspoint, transceiver kana FPGA package isingakwanise kupukunyuka zvakanaka nekushandisa nzira dzemazuva ano, kana kana saizi yebhodhi uye huwandu hwenzira dzichida lamination yakatevedzana. Hazvifanirwe kutaurwa chete nekuti chigadzirwa chine maports akawanda.

2. Per-Port EDID, HDCP, HPD uye Routing Control Architecture

Matrix inofanira kuchengetedza hukama hwakarongeka pakati pemanyuko akati wandei nemasink akati wandei. Chinobuda chega chega chinogona kuona EDID yakasiyana, uye zvinobuda zvakawanda zvinogona kupihwa kune chimwe chinhu panguva imwe chete.

• EDID pakuisa chimwe nechimwe: Chigadzirwa chinofanira kutsanangura kana sosi yega yega ichigamuchira EDID yakatarwa, EDID yesinki yakasarudzwa kana profile yesimba rakabatanidzwa.
• Kutevedzana kweHPD: Kuchinja nzira, kubatanidza/kubvisa sink uye kuchinja kwe standby kunofanirwa kutevedzera mutemo we firmware nemaune.
• Kutarisira kudzokorora kweHDCP: Kusimbiswa kwakachengeteka pamidziyo yakawanda iri pasi pemvura chikamu chekushandiswa kwechigadzirwa chine rezenisi. Kuronga mapurogiramu nekuyedza zvinofanirwa kuremekedza zvidzoro zvekuchengetedza zveOEM.
• Kutumira manzwi kuCEC/kuteerera: CEC uye kuburitsa/kuisa odhiyo zvinova zvakaoma mu matrix. Seti yezvinhu zvinofanira kunyorwa zvakajeka panzira imwe neimwe kana pachiteshi.
• Purosesa yekudzora: Firmware yeMCU/FPGA inofanira kuramba yakabatana nekuvandudzwa kweIC matrix, board routing map uye port labels.

Nekuti software inodzora jira rekushandura rine logic, bvunzo yekuenderera mberi kwehardware chete haigone kusimbisa chigadzirwa che matrix. Firmware nematafura ekugadzirisa zvinhu chikamu chegadziriro yekugadzira.

3. Kuungana kwePCB, Kuongororwa kweBGA/FPGA uye Kurongeka kweConnector

Ma matrices ane ma port-count akawanda anowanzo shandisa ma BGA makuru, ma HDMI connectors akawanda uye ma power converters akawanda. Zvinodzora mashandiro zvinofanirwa kusarudzwa kuti zvive zve thermal mass chaiyo uye package set.

• Kuungana kweBGA/FPGA: Highleap inogona kushanda Musangano weBGA PCB nzira dzekushandisa ma processor epakati, ma crosspoints uye ndangariro.
• Kuwanikwa kwemari kwakatenderwa: Matransceiver eHDMI, FPGA/crosspoint devices, retimers, memories uye wachi dzinofanira kutevedzera zvinodiwa nevatengi. chikamu chekutsvaga mitemo.
• AOI: AOI muPCBA inogona kuona mapassive anooneka uye connector soldering mumabhanga echiteshi chakasimba.
• X-ray: X-ray kuongorora yakakodzera nzvimbo dzakavanzwa dzeBGA/LGA uko hurongwa hwemhando hunoda izvozvo.
• Kurongeka kwekubatanidza/kukomberedza: Ma "receipts" makuru eHDMI anogona kuunganidzwa. Bhodhi, panel yekumberi/yekumashure uye dhizaini yemakanika zvinofanira kunge zvakafanana.

Sei connector array ichifanira kuongororwa ne mechanically usati waedza kekupedzisira?

Chinobatanidza chinogona kusungirirwa nemagetsi asi chichiri chakakwirira zvakanyanya, chakarereka kana kuti chakaderedzwa kuti chisabatane nepakati penzvimbo yacho. Zvigadzirwa zvematrix zvine maports akawanda akabatana zvakanyanya zvinonyanya kukanganiswa ne cumulative panel uye PCB tolerances.

4. Kuedza Kunoshanda Kwenzira-Matrix uye Kusimbiswa Kwekupisa

Kuedza nzira yega yega yekufunga kunogona kutora nguva, asi hurongwa hwekugadzira hunofanira kuramba huchiratidza kuti maports ese nejira rekuchinja rakagadzirwa zvakanaka. OEM inofanira kutsanangura matrix inoshanda yekuvhara.

• Kuzivikanwa kwechiteshi: Simbisa kuti chinobatanidza chega chega chinoenda kunhamba yekuisa/kuburitsa firmware.
• Kuvhara nzira: Shandisa zvese zvinopinda uye zvinobuda nehurongwa hwakanyorwa hwekubatanidza nzira dzekufambisa.
• Bandwidth yakanyanya kuipa: Edza nzira yepamusoro-soro yedata inosarudzwa nemutengi pamienzaniso kana nzira dzese dzinodiwa.
• Kushanda panguva imwe chete: Shandisa huwandu hwakatarwa hwezvinobatanidza zvinoshanda kuti utarise simba uye kugadzikana kwekupisa.
• FCT yekugadzira: Highleap inogona kuita kushanda kushanda uchishandisa nzira inotenderwa nemutengi, gadziriro yenzvimbo/sinki uye zvinodiwa zvekupasa/kukundikana.

5. Kuburitswa Kwekugadzirwa uye RFQ Data yeHDMI Matrix Switch PCB Manufacturing

RFQ inofanira kutaura saizi yematrix, zvinodiwa panguva imwe chete panzira uye mwero wedata raunoda nekuti ma parameter aya anotyaira nhamba yezvikamu, kubuda kweBGA, nhamba yeconnector, dhizaini yesimba uye kuoma kwekuyedza.

• Pakeji yekugadzira: Kuisa zvinhu mudenga, kupindira, HDI/kuburikidza nekuvakwa kana zvikashandiswa, ukobvu hwakapedzwa uye geometry yekubatanidza inodzorwa.
• Magadzirirwo eMatrix: MaMPN eCrosspoint/transceiver/FPGA, huwandu hwezvinoiswa/zvinobuda, ndangariro, zvinodzoreredza nguva uye nguva yekushanda.
