Kusarudza Yakakwana Rigid-Flex Circuit Stackup: A Comprehensive Guide

Mune ino blog, isu tichakurukura zvakakosha zvinhu zvekufunga kana uchisarudza yakanakira flex nzvimbo stackup yeakaomesesa-flex edunhu mabhodhi.

Munyika yemabhodhi edunhu akadhindwa (PCBs), kune marudzi mazhinji anoenderana nezvinodiwa zvakasiyana uye zvinodiwa. Imwe mhando yakave yakakurumbira mumakore achangopfuura ndeye rigid-flex circuit board. Aya mabhodhi anopa ese ari maviri anochinjika uye akaomeswa zvikamu, achibvumira kune akasanganiswa mabhenefiti ekuchinja uye kugadzikana. Nekudaro, kana uchigadzira rigid-flex wedunhu mabhodhi, chinhu chakakosha chinoda kunyatsotariswa ndechekusarudza iyo chaiyo stack yenzvimbo dzinochinjika.

Flex area stacking inoreva kurongeka kwezvikamu muchikamu chinoshanduka cheiyo rigid-flex circuit board. Inoita basa rakakosha mukuona kuita kwese uye kuvimbika kwebhodhi rimwechete. Kusarudza stackup yakakodzera kunoda kunyatsonzwisiswa kwechishandiso chakananga chebhodhi, zvinhu zvinoshandiswa, uye maitiro anodiwa ekuita.

1. Nzwisisa kuchinjika zvinodiwa:

Nhanho yekutanga pakusarudza iyo flex flex area layup kuve nekunzwisisa kwakajeka kwezvido zvebhodhi. Funga nezvechinangwa chekushandiswa uye kufamba kana kukotamisa bhodhi zvingada kutsungirira panguva yekushanda. Izvi zvichakubatsira kuona huwandu hwematanho anochinjika uye chaiwo zvinhu zvekushandisa.

2. Ongorora chiratidzo uye kuvimbika kwesimba:

Chiratidzo uye kutendeseka kwesimba zvinhu zvakakosha zvechero redunhu bhodhi dhizaini. Mune rigid-flex board, kurongedza kwenzvimbo dzinochinjika kunogona kukanganisa zvakanyanya chiratidzo uye simba rekugovera kutendeseka. Ongorora dhizaini yako yakakwira-kumhanya chiratidzo chinodiwa, impedance control, uye simba rekugovera zvinodiwa. Izvi zvichakubatsira kuona kurongeka kwakakodzera kwechiratidzo, pasi, uye ndege dzemagetsi munzvimbo inoshanduka.

3. Ongorora zvinhu zvekushandisa:

Kusarudzwa kwenzvimbo inochinjika laminate zvinhu kwakakosha kuti uwane inodiwa maitiro ekuita. Zvishandiso zvakasiyana zvinoratidza madhigirii akasiyana ekuchinja, kusimba, uye dielectric zvivakwa. Funga zvinhu zvakaita se polyimide, liquid crystal polymer, uye inoshanduka solder mask. Ongorora mashandiro avo emagetsi nemagetsi kuti asangane nezvido zvako.

4. Funga nezvezvakatipoteredza uye zvakavimbika zvinhu:

Paunenge uchisarudza inochinjika nzvimbo stack, mamiriro ezvakatipoteredza umo rigid-flex circuit mabhodhi achashanda anofanirwa kutariswa. Zvinhu zvakadai sekuchinja kwekushisa, humidity, uye kuratidzwa kumakemikari kana vibration zvinogona kukanganisa kushanda kwebhodhi redunhu uye kuvimbika. Sarudza zvinhu uye marongero ekugadzirisa anogona kumira aya mamiriro kuti ave nechokwadi chekuvimbika kwenguva refu.

5. Shanda nemugadziri wako wePCB:

Nepo iwe ungave uine zano rakanaka rezvaunoda dhizaini, kushanda nePCB mugadziri wako kwakakosha kuti ubudirire kusarudza iyo chaiyo flex nzvimbo stackup. Vane hunyanzvi uye ruzivo rwekushanda nemabhodhi edunhu anochinjika uye vanogona kupa ruzivo rwakakosha uye zano. Shanda padhuze navo kuti uve nechokwadi chekuti zvibodzwa zvako zvekugadzira zvinoenderana nekugoneka kwekugadzira.

Ramba uchifunga kuti yega yega yakaomesesa-flex yedunhu dhizaini yakasarudzika, uye hapana imwe-saizi-inokodzera-yese nzira yekusarudza yakanakira flex nzvimbo stackup. Zvinoda kunyatsoongorora, kutariswa kwezvinhu zvakasiyana-siyana, uye kubatana nenyanzvi mumunda. Kutora nguva yekuita sarudzo yakanaka kunozoguma nepamusoro-kuita, yakavimbika, uye yakasimba rigid-flex circuit board.

Muchidimbu

Kusarudza iyo chaiyo flex nzvimbo stackup yeiyo rigid-flex yedunhu bhodhi yakakosha kukuita kwayo kwese uye kuvimbika. Kunzwisisa kuchinjika zvinodiwa, kuongorora chiratidzo uye kuvimbika kwesimba, kuongorora zvivakwa zvezvinhu, kufunga nezvezvakatipoteredza, uye kushanda nemugadziri wePCB matanho akakosha mukuita sarudzo. Nekutevera nhungamiro idzi, unogona kuve nechokwadi chekubudirira kwekugadzira rigid-flex redunhu bhodhi rinosangana nezvido zvako uye zvaunoda.
