Paunenge uchigadzira rigid-flex redunhu bhodhi, chimwe chezvinhu zvakakosha zvekufunga nezve nzira yekutevera. Tsanangudzo dziri pabhodhi redunhu dzinoita basa rakakosha pakuona kushanda kwakakodzera kwezvinhu zvemagetsi.Mune ino blog positi, isu tichakurukura akajairwa dhizaini nhungamiro yekufambisa mune rigid-flex redunhu mabhodhi.
1. Tsvaira hupamhi nepakati:
Hupamhi hwekutsvagisa chinhu chakakosha pakuona iyo ikozvino kutakura kugona uye impedance. Zvinokurudzirwa kushandisa zvakapamhama zvicherwa zvekubatana kwazvino zvakanyanya kudzivirira kupisa kwakanyanya uye kutadza kutadza. Saizvozvo, kupatsanura pakati pemateki kunofanirwa kukwana kudzivirira crosstalk uye electromagnetic interference (EMI). Tsanangudzo yehupamhi uye nhungamiro yepakati inogona kusiyana zvichienderana nezvinodiwa zvebhodhi uye zvikamu zvaro.
2. Signal kutendeseka uye impedance control:
Kutendeseka kwechiratidzo chinhu chakakosha kutariswa mukugadzira bhodhi redunhu. Rigid-flex boards anowanzo aine zvinhu zvine akasiyana impedance zvinodiwa, senge microstrip uye stripline transmission tambo. Izvo zvakakosha kuti uchengetedze impedance inoenderana mukati meiyo nzira yekufambisa kuti uderedze zviratidzo zvechiratidzo uye kuve nechokwadi chekuita kwakakwana. Zvishandiso senge impedance Calculator uye simulation software inogona kubatsira kuwana chaiyo impedance control.
3. Layer stacking uye inochinjika kubhenda nzvimbo:
Rigid-flex circuit mabhodhi anowanzo kuumbwa nezvikamu zvakawanda, kusanganisira zvikamu zvakasimba uye zvikamu zvinoshanduka. Kurongeka uye mafambisirwo ezvironda pazvikamu zvakasiyana zvinofanirwa kunyatsotariswa kudzivirira kukanganiswa kwechiratidzo uye kuchengetedza kuchinjika kwebhodhi. Izvo zvinodikanwa kuti uone nzvimbo idzo bhodhi richakotama uye kudzivirira kuisa zvakakomba munzvimbo idzi, sezvo kubhenda kwakanyanya kunogona kukonzera kuti trace ityoke kana kutadza.
4. Yakasiyana pairing nzira:
Mumagadzirirwo emagetsi emazuva ano, mapeya akasiyana-siyana anowanzoshandiswa kune yakakwirira-kumhanya masaini kuti ave nechokwadi chekufambisa data. Paunenge uchifambisa mapeya akasiyana-siyana mumabhodhi akaoma-flex, zvakakosha kuchengetedza hurefu hwakafanana uye nzvimbo pakati pematanho kuchengetedza kutendeseka kwechiratidzo. Chero kusawirirana kunogona kukonzera kukanganisa kwenguva kana kukanganiswa kwechiratidzo, zvichikanganisa kuita kwese kwedunhu.
5. Kuburikidza nemagadzirirwo uye fan-kunze:
Vias chinhu chakakosha mudhizaini bhodhi dhizaini nekuti vanopa kubatanidza kwemagetsi pakati pezvikamu zvakasiyana. Yakakodzera kuburikidza nemagadzirirwo uye fan-out matekiniki anobatsira kuchengetedza chiratidzo chekuvimbika uye kuve nechokwadi chekubatana kwakavimbika. Izvo zvakakosha kudzivirira kuisa vias padhuze zvakanyanya nepamusoro-kumhanya zvitekidzwa sezvo ivo vanogona kusuma maratidziro kana impedance mismatches.
6. EMI uye Grounding:
Electromagnetic interference (EMI) inogona kukanganisa mashandiro emidziyo yemagetsi. Kuti uderedze EMI, ita shuwa yekuteerera kune nzira dzekudzika uye nekungwarira nzira wiring padhuze nezvinoita zvinhu. Ndege yakasimba yepasi inogona kuita senhoo uye kuderedza EMI. Nekuona nzira dzekudzika pasi, ruzha runogona kuderedzwa uye crosstalk inogona kudzikiswa, nekudaro ichivandudza kuita kwese.
Muchidimbu
Kugadzira rigid-flex circuit board inoda kunyatsotariswa kwezvinhu zvakasiyana-siyana, uye kutsvaga nzira chinhu chakakosha chinokanganisa zvakanyanya kushanda kwese uye kuvimbika kwedunhu. Nekutevera zvakajairwa dhizaini dhizaini inokurukurwa mune ino blog positi, mainjiniya anogona kuve neyakakwana chiratidzo chekuvimbika, impedance control, uye kuderedza EMI, zvichikonzera emhando yepamusoro uye yakasimba redunhu bhodhi dhizaini.Shenzhen Capel Technology Co., Ltd.inogadzira yakasimba inochinjika pcb uye inochinjika pcb kubvira 2009 uye ine makore gumi nemashanu chirongwa ruzivo muindasitiri yePC.
