Edza kushanda kweiyo rigid flex circuit board

Wakambozvibvunza here kuti ungayedza sei mashandiro eiyo rigid-flex circuit board? Usazeza zvakare! Mune ino blog post, isu tichaongorora nzira dzakasiyana uye marongero ekuona kushanda kwakaringana kweakaoma-flex edunhu mabhodhi. Kunyangwe iwe uri nyanzvi ine ruzivo kana mutsva kumunda, aya matipi uye matekiniki achakubatsira iwe kunyatso kuyedza kushanda kweakaomesesa-flex edunhu mabhodhi.

Tisati tanyura munzira dzakasiyana dzekuyedza, ngatitsanangure muchidimbu kuti rigid-flex circuit board chii. Rigid-flex circuit mabhodhi musanganiswa weakaomarara uye anochinjika edunhu mabhodhi, achigadzira dhizaini yakasanganiswa inopa zvakanakisa zvepasirese. Aya mabhodhi anowanzo shandiswa mumashandisirwo apo nzvimbo ine shoma uye kusimba uye kuvimbika kwakakosha.

Zvino, ngatienderere mberi kune musoro mukuru wechinyorwa ichi - kuyedza kushanda kweakaomesesa-flex edunhu mabhodhi. Pane bvunzo dzinoverengeka dzaunogona kuita kuti uone kuti bhodhi rako riri kushanda sezvaitarisirwa. Ngationgororei dzimwe dzebvunzo idzi zvakadzama.

1. Kuongorora kwekuona kweakaoma anochinjika edunhu mabhodhi:

Nhanho yekutanga mukuyedza kushanda kweiyo rigid-flex circuit board ndeyekuiongorora nemaziso kuona chero kukuvara kwemuviri kana kukanganisa kugadzira. Tarisa chero zviratidzo zvekutsemuka, kutsemuka, nyaya dzewelding kana kusaenzana. Iri inhanho yakakosha yekutanga pakuona chero nyaya dzinoonekwa dzinogona kukanganisa kushanda kwese kwebhodhi.

2. Kuenderera mberi bvunzo yakasimba inochinjika pcb mapuranga:

Muedzo wekuenderera mberi unoitwa kutarisa kuti magetsi ekubatanidza pabhodhi redunhu haana kusimba. Uchishandisa multimeter, unogona kukurumidza kuona kana paine zororo kana kuvhurika mune conductive trace. Nekuongorora akasiyana mapoinzi ekubatanidza, unogona kuona kuti dunhu rakwana uye masaini ari kuyerera nemazvo.

3. Impedance bvunzo yemabhodhi akaomarara:

Impedance kuyedzwa kwakakosha kuti uone kuti iyo impedance hunhu hwematehwe pabhodhi redunhu iri mukati memiganhu yakatarwa. Muedzo uyu unova nechokwadi chekuti chiratidzo hachikanganiswe nechero impedance mismatch, iyo inogona kukonzeresa kusaina kutendeseka nyaya.

4. Kushanda kuyedza kwemabhodhi akaomesesa akadhindwa edunhu:

Kuedza kushanda kunosanganisira kusimbisa kushanda kwebhodhi redunhu kuburikidza nekuedza mabasa ayo akasiyana-siyana. Izvi zvinogona kusanganisira kuyedza zvipimo uye zvinobuda, kuita zvirongwa zvakati kana kodhi, uye kutevedzera zviitiko zvehupenyu chaihwo kuti bhodhi rishande sezvaitarisirwa.

5. Kuedzwa kwezvakatipoteredza kune yakaoma flex pcb redunhu mapuranga:

Rigid-flex circuit mabhodhi anowanzo kuratidzwa kune akasiyana mamiriro ezvakatipoteredza. Naizvozvo, kuyedzwa kwezvakatipoteredza kunodiwa kuti uongorore mashandiro emabhodhi edunhu pasi pemamiriro akasiyana senge tembiricha, humidity, vibration, kana kushushikana kwekushisa. Kuyedzwa uku kunobatsira kuona kuti bhodhi rinogona kumira nemamiriro ekushanda anotarisirwa pasina kushatiswa kwekushanda.

6. Chiratidzo chekuvimbika bvunzo yeingid inoshanduka edunhu mabhodhi:

Signal kutendeseka kuyedzwa kunoitwa kuona kuti chiratidzo chinofambiswa kuburikidza nedunhu bhodhi pasina kukanganisa kana kukanganisa. Iko kuyedzwa kunosanganisira kuongorora mhando yechiratidzo uye kuyera ma paramita akadai se crosstalk, jitter uye dhiyagiramu yeziso kuti ive nechokwadi chekuita kwakakwana.
Pamusoro peiyo chaiyo bvunzo, zvakakosha kutevedzera zvakanakisa maitiro panguva yekugadzira uye nhanho dzekugadzira kuti uve nechokwadi chepamusoro mukana wekuwana inoshanda zvakanaka rigid-flex board. Izvi zvinosanganisira kunyatsoongorora dhizaini, kusarudzwa kwezvinhu kwakakodzera, uye kunoenderanakuongororwa kwemhando panguva yekugadzira.

Muchidimbu:

Kuedza kushanda kweiyo rigid-flex circuit board inhanho yakakosha mukuona kushanda kwayo kwakaringana. Kuburikidza nekutarisa kwekuona, kuenderera mberi kuyedza, impedance kuyedzwa, mashandiro ekuyedza, kuyedza kwezvakatipoteredza, uye chiratidzo chekuvimbika kuyedzwa, unogona kuona nekugadzirisa chero zvingangoitika zvingakanganisa kuita kwebhodhi rako. Nekutevera idzi nzira dzekuyedza uye akanakisa maitiro, unogona kuve nekuvimba mukushanda uye kuvimbika kweakaomesesa-flex edunhu mabhodhi.
