Mafungiro ekugadzira matunhu ekukotama eiyo rigid flex circuit board

Paunenge uchigadzira nzvimbo dzinochinjika dzeakaomesesa-flex edunhu mabhodhi, mainjiniya nevagadziri vanofanirwa kufunga zvakati wandei zvakakosha. Aya mafungidziro akakosha pakuona kutendeseka kwebhodhi, kuvimbika, uye kushanda mumashandisirwo anoda kuchinjika. Mune ino blog positi, isu tinonyura mune izvi kufunga uye kukurukura kukosha kwechimwe nechimwe.

1. Kusarudzwa kwezvinhu:

Kusarudzwa kweiyo rigid-flex circuit board material yakakosha pakuona kugona kwayo kupeta. Zvishandiso zvinoshandiswa zvinofanirwa kuve nekuchinjika kwakakosha uye kusimba kutsungirira kudzokororwa kukotama pasina kukanganisa kuvimbika kwedunhu. Zvishandiso zvakajairika zvezvikamu zvinochinjika zvinosanganisira polyimide (PI) uye polyester (PET), nepo akaomeswa akaturikidzana achiwanzo gadzirwa neFR4 kana zvimwe zvechinyakare redunhu bhodhi zvinhu. Izvo zvakakosha kuti usarudze chinhu chinogona kumirisana neinodiwa yekubhenda radius uye inotarisirwa nhamba yekukombama kutenderera.

2. Kupeta radius:

Bend radius ndiyo diki radius iyo yakasimba-flex yedunhu bhodhi inogona kukotama pasina kukonzeresa kukuvadza kune zvikamu, conductive traces, kana bhodhi pacharo. Izvo zvakakosha kuti uone iyo yakakodzera bend radius kune chaiyo application uye kuve nechokwadi chekuti zvinhu zvakasarudzwa zvinogona kuita izvi zvinodiwa. Pakusarudza iyo yakakodzera bend radius, vagadziri vanofanirwa kufunga nezvehukuru uye marongero echikamu, nzvimbo iri pakati pemaitiro ekufambisa, uye ukobvu hweiyo flex layer.

3. Traceroute:

Routing of conductive trace in the bend area ndiyo imwe pfungwa inokosha. Matare anofanirwa kugadzirwa nenzira inoita kuti akwanise kukotama pasina kutyoka kana kusangana nekushushikana zvisina kufanira. Kuti uite izvi, vagadziri vanowanzo shandisa curved trace routing panzvimbo yemakona akapinza nekuti macurved trace anonyanya kushingirira kushushikana. Pamusoro pezvo, maronda ari munzvimbo inobhenda anofanirwa kuiswa kure neasarerekera bend axis kudzivirira kutambanudza zvakanyanya kana kudzvanya panguva yekukotama.

4. Kuiswa kwechikamu:

Kushanda kwechikamu kuiswa kwakakosha pakuona kuvimbika uye kushanda kweakaomesesa-flex circuit board. Zvikamu zvinofanirwa kuiswa zvine hungwaru kuderedza kushushikana pabhodhi panguva yekukotama. Izvo zvakakosha kuti titarise mabatiro ezvikamu senge majoini ane pazere kuchinjika kwebhodhi. Kuisa zvinhu zvakakura kana zvakaomarara zvakanyanya pedyo nenzvimbo yekubhenda zvinogona kudzikisira kugona kwebhodhi kukotama zvakanaka kana kuwedzera njodzi yekukuvara kwechikamu.

5. Nzira yekufambisa:

Yakanyatsogadzirirwa nzira dzekufambisa dzinogona kubatsira kufambisa kupeta uye kuchinjika kweakaomesesa-flex edunhu mabhodhi. Aya machanera inzvimbo munzvimbo dzakaomarara dzinobvumira iyo inochinjika layer kuti ifambe yakasununguka panguva yekukotama. Nekupa aya machani, mainjiniya anogona kuderedza kushushikana pane iyo flex layer uye kudzivirira kushushikana kusingakoshi pamateki. Hupamhi nekudzika kwenzira dzekufambisa dzinofanira kunyatsogadziriswa kuti ive nechokwadi chekuenderana neinodiwa bend radius.

6. Kuedza uye simulation:

Usati wapedza dhizaini yeakaomesesa-flex redunhu bhodhi, zvakakosha kuti unyatso kuyedza uye simulation kuti uone kushanda kwayo pasi pekukotama mamiriro. Kushandisa nzira dzekuyedza dzechokwadi kana dzemuviri dzinogona kubatsira kuona zvingangoitika senge wakanyanya kudzvanywa, majoini asina simba emasoja, kana kurongeka kwechikamu. Maturusi ekuenzanisa uye matekiniki anonyanya kubatsira pakugadzirisa madhizaini uye kuve nechokwadi chepamusoro flexural performance yemabhodhi edunhu.

Muchidimbu

Kugadzira iyo inochinjika nzvimbo yeakaomesesa-flex wedunhu bhodhi inoda kunyatso tarisisa akati wandei akakosha zvinhu. Kusarudzwa kwezvinhu, bend radius, kuronda nzira, kuiswa kwechikamu, nzira dzenzira, uye kuyedzwa zvese zvinhu zvakakosha zvinofanirwa kugadziriswa kuti ive nechokwadi chekuvimbika nekushanda kwebhodhi. Nekuteerera kune aya mafungidziro, mainjiniya nevagadziri vanogona kugadzira akaomesesa-flex edunhu mabhodhi anosangana nezvinodiwa zvekuchinjika maapplication uku vachichengetedza kuvimbika kwavo nekuita.
