Kusankha Perfect Rigid-Flex Circuit Stackup: A Comprehensive Guide

Mu blog iyi, tikambirana zinthu zazikuluzikulu zomwe muyenera kuziganizira posankha ma flex area stackup for rigid-flex circuit board.

M'dziko la matabwa osindikizira (PCBs), pali mitundu yambiri yogwirizana ndi zosowa ndi zofunikira zosiyanasiyana.Mtundu umodzi womwe wadziwika kwambiri m'zaka zaposachedwa ndi bolodi lozungulira lokhazikika.Mapulaniwa amapereka magawo osinthika komanso okhwima, zomwe zimapangitsa kuti pakhale phindu lophatikizana la kusinthasintha ndi kukhazikika.Komabe, popanga ma rigid-flex circuit board, chinthu chofunikira kwambiri chomwe chimafunika kuganiziridwa mosamala ndikusankha malo oyenera osinthika.

Flex area stacking imatanthawuza makonzedwe a zigawo mu gawo losinthika la bolodi lozungulira lokhazikika.Zimagwira ntchito yofunika kwambiri pakuwonetsetsa kuti gulu limodzi likugwira ntchito komanso kudalirika.Kusankha stackup yoyenera kumafuna kumvetsetsa bwino momwe bolodi imagwiritsidwira ntchito, zida zomwe zimagwiritsidwa ntchito, ndi machitidwe ofunikira.

1. Mvetserani zofunika kusinthasintha:

Chinthu choyamba posankha malo oyenera osinthika ndikumvetsetsa bwino zomwe gulu likufunikira.Ganizirani zomwe mukufuna kugwiritsa ntchito komanso kusuntha kapena kupindika bolodi kungafunike kupirira panthawi yogwira ntchito.Izi zikuthandizani kudziwa kuchuluka kwa magawo osinthika komanso zida zenizeni zomwe mungagwiritse ntchito.

2. Unikani chizindikiro ndi kukhulupirika kwamphamvu:

Chizindikiro ndi kukhulupirika kwamphamvu ndizofunikira kwambiri pamapangidwe aliwonse a board board.M'ma board okhazikika, kusungitsa madera osinthika kumatha kukhudza kwambiri kukhulupirika komanso kugawa mphamvu.Yang'anani zofunikira zamasinthidwe othamanga kwambiri pamapangidwe anu, kuwongolera kwa impedance, ndi zosowa zogawa mphamvu.Izi zidzakuthandizani kudziwa makonzedwe oyenera a ma siginali, pansi, ndi ndege zamphamvu m’malo osinthasintha.

3. Unikani zakuthupi:

Kusankhidwa kwa zida zosinthika za laminate ndikofunikira kuti mukwaniritse zomwe mukufuna kuchita.Zida zosiyanasiyana zimasonyeza kusinthasintha, kusinthasintha, ndi dielectric properties.Ganizirani zinthu monga polyimide, liquid crystal polymer, ndi flexible solder mask.Unikani makina awo ndi magetsi kuti akwaniritse zomwe mukufuna.

4. Ganizirani za chilengedwe ndi zodalirika:

Posankha malo osinthika osinthika, mikhalidwe yachilengedwe yomwe ma board ozungulira okhazikika adzagwira ntchito iyenera kuganiziridwa.Zinthu monga kusintha kwa kutentha, chinyezi, komanso kukhudzana ndi mankhwala kapena kugwedezeka kungakhudze magwiridwe antchito ndi kudalirika kwa bolodi.Sankhani zipangizo ndi masanjidwe masanjidwe amene angathe kupirira mikhalidwe imeneyi kuonetsetsa kudalirika kwa nthawi yaitali.

5. Gwirani ntchito ndi wopanga PCB wanu:

Ngakhale mungakhale ndi lingaliro labwino la kapangidwe kanu, kugwira ntchito ndi wopanga PCB ndikofunikira kuti musankhe bwino malo oyenera osinthira.Ali ndi ukadaulo komanso luso logwira ntchito ndi ma board osinthika ndipo amatha kupereka luntha ndi upangiri wofunikira.Gwirani ntchito limodzi nawo kuti muwonetsetse kuti zolinga zanu zapangidwe zikugwirizana ndi kuthekera kopanga.

Kumbukirani kuti kamangidwe kalikonse kolimba kozungulira ka board ndi kosiyana, ndipo palibe njira yofanana yosankha malo oyenera osinthira.Pamafunika kusanthula mosamala, kulingalira zinthu zosiyanasiyana, ndi kugwirizana ndi akatswiri pankhaniyi.Kutenga nthawi kuti mupange chisankho choyenera kudzapangitsa kuti pakhale bolodi yogwira ntchito kwambiri, yodalirika, komanso yokhazikika yokhazikika.

Powombetsa mkota

Kusankha malo osinthika olondola a bolodi lozungulira lokhazikika ndikofunikira kwambiri pakuchita kwake konse komanso kudalirika kwake.Kumvetsetsa zofunikira zosinthika, kusanthula chizindikiro ndi kukhulupirika kwa mphamvu, kuyesa zinthu zakuthupi, kuganizira za chilengedwe, ndikugwira ntchito ndi wopanga PCB ndi njira zofunika kwambiri pakusankha.Potsatira malangizowa, mutha kuwonetsetsa kuti mukuchita bwino popanga bolodi lozungulira lokhazikika lomwe limakwaniritsa zosowa zanu ndi zomwe mukufuna.
