Flex PCB Assembly Imasiyana ndi Msonkhano Wokhazikika wa PCB Mu Njira Yopangira

Msonkhano wa PCB (Printed Circuit Board) ndi gawo lofunikira popanga zamagetsi. Zimakhudzanso kuyika ndi kugulitsa zida zamagetsi pa PCB. Pali mitundu iwiri ikuluikulu ya misonkhano PCB, kusintha PCB misonkhano ndi okhwima PCB misonkhano. Ngakhale onsewa amagwira ntchito yofanana yolumikizira zida zamagetsi, amapangidwa mosiyana.Mu blog iyi, tikambirana momwe flex PCB msonkhano amasiyana okhwima PCB msonkhano popanga ndondomeko.

1. Msonkhano wa FPC:

Flex PCB, yomwe imadziwikanso kuti PCB yosinthika, ndi bolodi yozungulira yomwe imatha kupindika, kupindika kapena kupindika kuti igwirizane ndi mawonekedwe ndi masanjidwe osiyanasiyana.Imakhala ndi maubwino angapo kuposa ma PCB olimba, monga kuchepetsa kugwiritsa ntchito malo komanso kukhazikika kwamphamvu. Kupanga kwa flex PCB msonkhano kumaphatikizapo izi:

a. Flexible PCB Design: Gawo loyamba la msonkhano wosinthika wa PCB ndikupanga masanjidwe osinthika adera.Izi zimaphatikizapo kudziwa kukula, mawonekedwe ndi masinthidwe a flex PCB. Kulingalira kwapadera kwaperekedwa ku dongosolo lazitsulo zamkuwa, vias ndi mapepala kuti zitsimikizire kusinthasintha ndi kudalirika.

b. Kusankha kwazinthu: Ma PCB osinthika amapangidwa ndi zinthu zosinthika monga polyimide (PI) kapena polyester (PET).Kusankhidwa kwa zinthu kumadalira zofunikira zomwe zimagwiritsidwa ntchito, kuphatikizapo kukana kutentha, kusinthasintha, ndi makina.

c. Kupanga madera: Kupanga kosinthika kwa PCB kumaphatikizapo njira monga photolithography, etching, ndi electroplating.Photolithography imagwiritsidwa ntchito kusamutsa machitidwe ozungulira ku magawo osinthika. Etching imachotsa mkuwa wosafunikira, ndikusiya dera lomwe mukufuna. Plating amachitidwa kuti apititse patsogolo conductivity ndi kuteteza madera.

d. Kuyika kwa chigawo: Pamsonkhano wosinthika wa PCB, zigawo zake zimayikidwa pagawo losinthika pogwiritsa ntchito ukadaulo wapamtunda (SMT) kapena ukadaulo wapabowo.SMT imaphatikizapo kuyika zida zamagetsi pamwamba pa PCB yosinthika, pomwe ukadaulo wodutsa m'mabowo umaphatikizapo kuyika zotsogola m'mabowo obowoledwa kale.

e. Soldering: Soldering ndi njira yolumikizira zida zamagetsi ku PCB yosinthika.Nthawi zambiri amachitidwa pogwiritsa ntchito reflow soldering kapena ma wave soldering njira, malingana ndi mtundu wa chigawocho ndi zofunikira za msonkhano.

2. Msonkhano wokhazikika wa PCB:

Ma PCB okhwima, monga momwe dzinalo likusonyezera, ndi matabwa ozungulira omwe sangapindike kapena kupindika.Nthawi zambiri amagwiritsidwa ntchito m'malo omwe kukhazikika kwadongosolo ndikofunikira. Njira yopangira msonkhano wokhazikika wa PCB imasiyana ndi msonkhano wa PCB wosinthika m'njira zingapo:

a. Mapangidwe Olimba a PCB: Mapangidwe okhwima a PCB nthawi zambiri amayang'ana pakukulitsa kachulukidwe kazinthu ndikukulitsa kukhulupirika kwa ma siginecha.Kukula, kuchuluka kwa zigawo, ndi kasinthidwe ka PCB zimatsimikiziridwa malinga ndi zofunikira za ntchito.

b. Kusankha kwazinthu: Ma PCB olimba amapangidwa pogwiritsa ntchito magawo olimba monga fiberglass (FR4) kapena epoxy.Zidazi zimakhala ndi mphamvu zabwino zamakina komanso kukhazikika kwamafuta ndipo ndizoyenera kugwiritsa ntchito zosiyanasiyana.

c. Kupanga mozungulira: Kupanga kolimba kwa PCB nthawi zambiri kumaphatikizapo masitepe ofanana ndi ma PCB osinthika, kuphatikiza kujambula zithunzi, etching, ndi plating.Komabe, zida zomwe zimagwiritsidwa ntchito ndi njira zopangira zimatha kusiyanasiyana kuti zigwirizane ndi kuuma kwa bolodi.

d. Kuyika kwazinthu: Zigawo zimayikidwa pa PCB yolimba pogwiritsa ntchito SMT kapena ukadaulo wapabowo, wofanana ndi msonkhano wosinthika wa PCB.Ma PCB okhwima, komabe, amalola masinthidwe ovuta kwambiri a zigawo chifukwa cha zomangamanga zolimba.

e. Soldering: The soldering ndondomeko kwa okhwima PCB msonkhano ndi ofanana ndi flex PCB msonkhano.Komabe, njira yeniyeni ndi kutentha komwe kumagwiritsidwa ntchito kumasiyana malinga ndi zipangizo ndi zigawo zomwe zimagulitsidwa.

Pomaliza:

Flexible PCB msonkhano ndi okhwima PCB msonkhano ndi osiyana kupanga njira chifukwa cha makhalidwe osiyanasiyana zipangizo ndi ntchito zawo.Ma PCB osinthika amapereka kusinthasintha komanso kukhazikika, pomwe ma PCB olimba amapereka kukhazikika kwadongosolo. Kudziwa kusiyana pakati pa mitundu iwiriyi ya misonkhano ya PCB ndikofunikira posankha njira yoyenera pakugwiritsa ntchito pakompyuta. Poganizira zinthu monga mawonekedwe, zofunikira zamakina ndi kusinthasintha, opanga amatha kuwonetsetsa kuti misonkhano ya PCB ndi yodalirika komanso yodalirika.
