Flex Circuit Fabrication: Ndi zinthu ziti zomwe zimagwiritsidwa ntchito nthawi zambiri?

Ma circuit flexible, omwe amadziwikanso kuti flexible printed circuit boards (PCBs), ndi zigawo zofunika kwambiri pa zipangizo zamakono zamakono. Kusinthasintha kwawo kumawalola kuti azolowere mawonekedwe ndi makulidwe osiyanasiyana, kuwapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira kupindika kapena kupindika. Kupanga ma flex circuit kumaphatikizapo njira zingapo, kuphatikizapo kusankha zipangizo zoyenera.Mu positi iyi yabulogu, tiwona zida zomwe zimagwiritsidwa ntchito popanga ma flex circuit ndi ntchito zomwe zimagwira powonetsetsa kulimba ndi magwiridwe antchito a mabwalowa.

Chimodzi mwazinthu zoyambirira zomwe zimagwiritsidwa ntchito popanga ma flex circuit ndi polyimide. Polyimide ndi chinthu chapulasitiki chosagwira kutentha kwambiri chomwe chimatha kupirira malo ovuta.Ili ndi kukhazikika kwabwino kwamafuta komanso mphamvu zotchingira magetsi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'mabwalo osinthika omwe amatha kukumana ndi kutentha kapena kuzizira kwambiri. Polyimide imagwiritsidwa ntchito ngati maziko kapena gawo lapansi la mabwalo osinthika.

Chinthu china chomwe chimagwiritsidwa ntchito kwambiri popanga ma flex circuit ndi mkuwa.Copper ndi kondakitala wabwino kwambiri wamagetsi, ndikupangitsa kuti ikhale yabwino kutumizira ma siginecha amagetsi mumayendedwe osinthika. Nthawi zambiri amapangidwa ndi laminated ku gawo lapansi la polyimide kuti apange ma conductive trace kapena mawaya pamagawo. Zojambula zamkuwa kapena mapepala amkuwa owonda nthawi zambiri amagwiritsidwa ntchito popanga. Makulidwe a mkuwa wosanjikiza amatha kusiyanasiyana malinga ndi zofunikira za ntchito.

Zipangizo zomatira ndizofunikanso pakupanga ma flex circuit.Zomatira zimagwiritsidwa ntchito kulumikiza zigawo zosiyanasiyana za flex circuit palimodzi, kuonetsetsa kuti dera limakhalabe losasunthika komanso losinthika. Zida ziwiri zomatira zomwe zimagwiritsidwa ntchito popanga ma flex circuit ndi zomatira zochokera ku acrylic ndi zomatira zochokera ku epoxy. Zomatira za Acrylic zimapereka kusinthasintha kwabwino, pomwe zomatira zochokera ku epoxy zimakhala zolimba komanso zolimba.

Kuphatikiza pazidazi, zophimba kapena zida za solder zimagwiritsidwa ntchito kuteteza ma conductive pama flex circuit.Zida zokutira nthawi zambiri zimapangidwa ndi polyimide kapena liquid photoimaging solder mask (LPI). Amagwiritsidwa ntchito pamayendedwe a conductive kuti apereke kutchinjiriza ndikuwateteza kuzinthu zachilengedwe monga chinyezi, fumbi ndi mankhwala. Chivundikirocho chimathandizanso kupewa maulendo afupikitsa komanso kumapangitsa kuti kudalirika konse kwa flex circuit.

Chinthu china chomwe chimagwiritsidwa ntchito popanga ma flex circuit ndi nthiti.Nthiti nthawi zambiri zimapangidwa ndi FR-4, chinthu chotchinga moto cha fiberglass epoxy. Amagwiritsidwa ntchito kulimbikitsa madera ena a flex circuit yomwe imafunikira chithandizo chowonjezera kapena kuuma. Nthiti zikhoza kuwonjezeredwa m'madera omwe zolumikizira kapena zigawo zikuluzikulu zimayikidwa kuti zipereke mphamvu zowonjezera ndi kukhazikika kwa dera.

Kuphatikiza pa zida zoyambira izi, zida zina monga ma solders, zokutira zoteteza, ndi zida zotchingira zingagwiritsidwe ntchito panthawi yopanga ma flex circuit.Chilichonse mwazinthuzi chimakhala ndi gawo lofunikira pakuwonetsetsa kuti magwiridwe antchito, kukhazikika komanso kudalirika kwa mabwalo osinthika munjira zosiyanasiyana.

Mwachidule, zida zomwe zimagwiritsidwa ntchito kwambiri popanga ma flex circuit zimaphatikizapo polyimide ngati gawo lapansi, mkuwa ngati njira yolumikizira, zomatira zomangira, zophimba zotchingira ndi chitetezo, ndi nthiti zolimbitsa.Chilichonse mwazinthu izi chimagwira ntchito inayake ndipo palimodzi chimakulitsa magwiridwe antchito ndi kudalirika kwa ma flex circuit. Kumvetsetsa ndi kusankha zipangizo zoyenera ndizofunikira kuti pakhale maulendo apamwamba osinthika omwe amakwaniritsa zofunikira za zipangizo zamakono zamakono.
