Kupanga matekinoloje a ma rigid-flex printed circuit board

Mu positi iyi yabulogu, tiwona matekinoloje osiyanasiyana opanga omwe amagwiritsidwa ntchito kupanga ma PCB osasunthika ndikuwunika kufunikira kwawo popanga.

Ma board osindikizira osasunthika (PCBs) akuchulukirachulukira m'makampani opanga zamagetsi chifukwa cha zabwino zawo zambiri kuposa ma PCB okhazikika kapena osinthika. Ma board anzeruwa amaphatikiza kusinthasintha ndi kulimba, kuwapangitsa kukhala abwino kwa mapulogalamu pomwe malo ndi ochepa komanso kulimba ndikofunikira. Kupanga matabwa olimba-flex kumaphatikizapo matekinoloje osiyanasiyana kuti atsimikizire kupanga bwino komanso kusonkhanitsa matabwa ozungulira.

1. Malingaliro opangira ndi kusankha zinthu:

Musanayambe kuyang'ana muukadaulo wopanga, kapangidwe kake ndi zinthu za PCB zokhazikika ziyenera kuganiziridwa. Mapangidwewo ayenera kukonzedwa mosamala, poganizira momwe bolodi ikufunira, zofunikira zosinthika, ndi kuchuluka kwa zigawo zofunika. Kusankhidwa kwa zinthu ndikofunika mofanana chifukwa kumakhudza ntchito yonse ndi kudalirika kwa bolodi. Kuzindikira kuphatikiza koyenera kwa magawo osinthika komanso olimba, zomatira, ndi zida zoyendetsera ndikofunikira kuti muwonetsetse zotsatira zomwe mukufuna.

2. Kupanga madera osinthika:

Njira yopangira ma flex circuit imaphatikizapo kupanga zigawo zosinthika pogwiritsa ntchito filimu ya polyimide kapena polyester ngati gawo lapansi. Kanemayo amakumana ndi njira zingapo monga kuyeretsa, kupaka, kujambula, etching ndi electroplating kuti apange dongosolo lomwe mukufuna. Chosanjikiza chosinthika chimaphatikizidwa ndi wosanjikiza wokhazikika kuti apange PCB yokhazikika yokhazikika.

3. Kupanga dera lokhazikika:

Gawo lolimba la PCB lokhazikika limapangidwa pogwiritsa ntchito njira zachikhalidwe zopangira PCB. Izi zikuphatikizapo njira monga kuyeretsa, kujambula, kujambula ndi kuyika laminates olimba. Chosanjikiza cholimbacho chimalumikizidwa ndikumangirizidwa ku gawo losinthika pogwiritsa ntchito zomatira zapadera.

4. Kubowola ndi plating:

Pambuyo popanga ma flex ndi olimba mabwalo, chotsatira ndikubowola mabowo kuti alole kuyika kwa zigawo ndi kulumikizana kwamagetsi. Kubowola mabowo mu PCB yolimba-yosinthika kumafuna kuyika bwino kuti zitsimikizire kuti mabowo omwe ali m'magawo opindika ndi olimba alumikizidwa. Pambuyo pobowola akamaliza, mabowo yokutidwa ndi zinthu conductive kukhazikitsa kugwirizana magetsi pakati pa zigawo zosiyanasiyana.

5. Kusintha kwa magawo:

Kuphatikizika kwa zigawo mu ma PCB okhwima kumatha kukhala kovuta chifukwa chophatikiza zinthu zosinthika komanso zolimba. Traditional surface Mount Technology (SMT) imagwiritsidwa ntchito pazinthu zolimba, pomwe matekinoloje ena monga flex bonding ndi flip-chip bonding amagwiritsidwa ntchito kumadera osinthika. Njirazi zimafuna ogwiritsira ntchito aluso ndi zida zapadera kuti zitsimikizire kuti zigawozo zimayikidwa bwino popanda kuyambitsa kupsinjika kulikonse pazigawo zosinthika.

6. Kuyesa ndi kuyendera:

Kuti muwonetsetse kuti ma board okhazikika ndi odalirika, kuyezetsa mozama ndi kuwunika kumafunika. Chitani mayeso osiyanasiyana monga kuyesa kupitilira kwamagetsi, kusanthula kukhulupirika kwa ma sign, kuyendetsa njinga zamoto ndi kuyesa kunjenjemera kuti muwone momwe gulu ladera likugwirira ntchito. Kuonjezera apo, fufuzani bwinobwino kuti muwone ngati pali zolakwika kapena zolakwika zomwe zingakhudze momwe gululo likugwirira ntchito.

7. Kumaliza komaliza:

Gawo lomaliza popanga PCB yokhazikika ndikuyika zokutira zoteteza kuti ziteteze kuzungulira kuzinthu zachilengedwe monga chinyezi, fumbi, ndi kusinthasintha kwa kutentha. Zopaka zimathandizanso kwambiri kukulitsa kulimba komanso kukana kwa bolodi.

Powombetsa mkota

Kupanga matabwa olimba-flex kumafuna kuphatikizika kwa njira zapadera zopangira ndikuganizira mosamala. Kuchokera pakupanga ndi kusankha zinthu mpaka kupanga, kusonkhanitsa chigawo, kuyesa ndi kumaliza, sitepe iliyonse ndiyofunikira kuti muwonetsetse kuti ntchito ndi moyo wautali wa bolodi lanu ladera. Pamene makampani opanga zamagetsi akupita patsogolo, matekinoloje apamwamba kwambiri komanso ogwira mtima akuyembekezeka kupititsa patsogolo chitukuko cha matabwa okhwima, kutsegulira mwayi watsopano wogwiritsa ntchito ntchito zosiyanasiyana.
