Ndi zinthu ziti zomwe zimagwiritsidwa ntchito mu rigid-flex Boards?

Mtundu umodzi wa bolodi wozungulira womwe ukuchulukirachulukira mumakampani opanga zamagetsi ndibolodi lolimba-flex.

Zikafika pazida zamagetsi monga ma foni a m'manja ndi laputopu, ntchito zamkati ndizofunikanso ngati kunja kokongola. Zigawo zomwe zimapanga zipangizozi zimagwira ntchito nthawi zambiri zimabisika pansi pa zigawo zamagulu kuti zitsimikizire kuti zimagwira ntchito komanso zimakhala zolimba. Koma ndi zipangizo ziti zomwe zimagwiritsidwa ntchito m'mabwalo oyendera maulendo atsopanowa?

Okhazikika-flex PCBamaphatikiza ubwino wa matabwa ozungulira ndi osinthasintha, kupereka njira yapadera ya zipangizo zomwe zimafuna kuphatikiza mphamvu zamakina ndi kusinthasintha. Ma board awa ndi othandiza makamaka pamapangidwe opangidwa ndi mbali zitatu kapena zida zomwe zimafunikira kupindika kapena kupindika pafupipafupi.

Tiyeni tiwone mwatsatanetsatane zida zomwe zimagwiritsidwa ntchito kwambiri pomanga PCB yokhazikika:

1. FR-4: FR-4 ndi galasi-retardant galasi-reinforced epoxy laminate chuma ntchito kwambiri makampani zamagetsi. Ndiwomwe amagwiritsidwa ntchito kwambiri pagawo laling'ono la ma PCB okhwima. FR-4 ili ndi zida zabwino kwambiri zotchinjiriza magetsi komanso mphamvu zamakina, zomwe zimapangitsa kuti zikhale zoyenera pamagulu olimba a matabwa ozungulira.

2. Polyimide: Polyimide ndi polima yotentha kwambiri yomwe nthawi zambiri imagwiritsidwa ntchito ngati gawo laling'ono losinthika mu matabwa okhwima. Ili ndi kukhazikika kwabwino kwamafuta, mphamvu zamagetsi zamagetsi komanso kusinthasintha kwamakina, kulola kupirira kupindika mobwerezabwereza ndi kupindika popanda kusokoneza umphumphu wa bolodi lozungulira.

3. Copper: Copper ndiye chinthu chachikulu chowongolera pama board olimba. Amagwiritsidwa ntchito popanga ma conductive traces ndi ma interconnections omwe amalola kuti magetsi aziyenda pakati pa zigawo pa board board. Mkuwa umakondedwa chifukwa chapamwamba kwambiri, kugulitsa bwino komanso kutsika mtengo.

4. Zomatira: Zomatira zimagwiritsidwa ntchito kulumikiza zigawo zolimba ndi zosinthika za PCB palimodzi. Ndikofunikira kusankha zomatira zomwe zimatha kupirira kupsinjika kwamafuta ndi makina omwe amakumana nawo panthawi yopanga komanso moyo wa zida. Zomatira za Thermoset, monga epoxy resins, zimagwiritsidwa ntchito kwambiri mu ma PCB osasunthika chifukwa cha kulumikizana kwawo kwakukulu komanso kukana kutentha kwambiri.

5. Coverlay: Coverlay ndi chitetezo chomwe chimagwiritsidwa ntchito kuphimba mbali yosinthika ya bolodi la dera. Nthawi zambiri amapangidwa kuchokera ku polyimide kapena zinthu zosinthika zofananira ndipo amagwiritsidwa ntchito kuteteza mawonekedwe osakhwima ndi zinthu zina kuchokera kuzinthu zachilengedwe monga chinyezi ndi fumbi.

6. Chigoba cha Solder: Chigoba cha solder ndi chosanjikiza choteteza chokutidwa pa gawo lolimba la PCB. Zimathandizira kupewa kutsekeka kwa solder ndi kabudula wamagetsi pomwe zimaperekanso chitetezo chambiri komanso dzimbiri.

Izi ndi zida zazikulu zomwe zimagwiritsidwa ntchito pomanga okhazikika a PCB.Komabe, ndikofunikira kudziwa kuti zida zenizeni ndi katundu wawo zimatha kusiyanasiyana malinga ndi momwe bolodi imagwiritsidwira ntchito komanso momwe akufunira. Opanga nthawi zambiri amasintha zinthu zomwe zimagwiritsidwa ntchito mu ma PCB okhwima kuti akwaniritse zofunikira za chipangizo chomwe amagwiritsidwa ntchito.

Powombetsa mkota,Ma PCB okhwima ndi odabwitsa kwambiri pamakampani opanga zamagetsi, omwe amapereka kuphatikiza kwapadera kwamphamvu zamakina komanso kusinthasintha. Zida zomwe zimagwiritsidwa ntchito monga FR-4, polyimide, mkuwa, zomatira, zokutira, ndi masks a solder zonse zimagwira ntchito komanso kulimba kwa matabwawa. Pomvetsetsa zida zomwe zimagwiritsidwa ntchito mu ma PCB okhwima, opanga ndi opanga amatha kupanga zida zamagetsi zapamwamba, zodalirika zomwe zimakwaniritsa zofunikira za dziko lamakono loyendetsedwa ndiukadaulo.
