Zosintha Zosindikizidwa Zozungulira | Polyimide Pcb | Mkuwa Pcb | Soldering Circuit Boards

M'nkhaniyi, tiwona mwatsatanetsatane zida zomwe zimagwiritsidwa ntchito kwambiriflexible kusindikizidwa dera kupanga.

Flexible printed circuits (FPC) asintha kwambiri gawo la zamagetsi. Kukhoza kwawo kupindika kumawapangitsa kukhala otchuka m'mafakitale osiyanasiyana kuphatikiza ndege, magalimoto, chisamaliro chaumoyo, komanso zamagetsi zamagetsi.

Chimodzi mwazinthu zazikulu zomwe zimagwiritsidwa ntchito popanga mabwalo osinthika osindikizidwa ndi polyimide.Polyimide ndi polima wochita bwino kwambiri wokhala ndi kukhazikika kwamafuta, kukana kwamankhwala komanso kulimba kwamakina. Izi zimapangitsa kuti zikhale zabwino kwa mabwalo osinthika chifukwa amatha kupirira kutentha kwambiri komanso malo ovuta popanda kusokoneza magwiridwe ake. Mafilimu opangidwa ndi polyimide amagwiritsidwa ntchito ngati gawo laling'ono la mabwalo osinthika osindikizidwa.

Kuphatikiza pa polyimide, chinthu china chomwe nthawi zambiri chimagwiritsidwa ntchito popanga makina osindikiza osinthika ndi mkuwa.Copper idasankhidwa chifukwa champhamvu yake yamagetsi, kukana dzimbiri komanso ductility. Chojambula chopyapyala chamkuwa nthawi zambiri chimayikidwa pagawo la polyimide kuti apange njira yoyendetsera dera. Chosanjikiza chamkuwa chimapereka zolumikizira zofunikira zamagetsi zomwe zimafunikira kuti dera liziyenda bwino.

Kuti muteteze mikwingwirima yamkuwa ndikuwonetsetsa kutalika kwa dera losindikizidwa losinthika, chivundikiro kapena chigoba cha solder chimafunika.Kuphimba ndi filimu yomatira ya thermoset yomwe nthawi zambiri imagwiritsidwa ntchito pamadera ozungulira. Zimakhala ngati zotchinga zoteteza, kuteteza mayendedwe amkuwa kuzinthu zachilengedwe monga chinyezi, fumbi, ndi kuwonongeka kwakuthupi. Chivundikirocho nthawi zambiri chimakhala filimu yopangidwa ndi polyimide, yomwe imakhala ndi mphamvu zomangirira kwambiri ndipo imatha kumangirizidwa mwamphamvu ku gawo lapansi la polyimide.

Pofuna kupititsa patsogolo kulimba ndi magwiridwe antchito a mabwalo osinthika osindikizidwa, zida zolimbikitsira monga tepi kapena zida zolimbikitsira zimagwiritsidwa ntchito nthawi zambiri.Onjezani zowonjezera kumadera ena a dera komwe kumafunikira mphamvu kapena kuuma kowonjezera. Zidazi zingaphatikizepo zosankha zosiyanasiyana, monga filimu ya polyimide kapena polyester, fiberglass, kapenanso zitsulo zachitsulo. Kulimbitsa kumathandiza kupewa mabwalo kuti asagwe kapena kusweka panthawi yoyenda kapena kugwira ntchito.

Kuonjezera apo, mapepala kapena mauthenga amawonjezedwa kuti athandize kugwirizana pakati pa makina osindikizira osinthika ndi zipangizo zina zamagetsi.Mapadi awa nthawi zambiri amapangidwa kuchokera kuzinthu zosakanikirana zamkuwa ndi zosagwirizana ndi solder. Mapadi opangira ma bonding amapereka mawonekedwe ofunikira opangira zida zolumikizira kapena zolumikizira monga ma circuits ophatikizika (ICs), resistors, capacitors, ndi zolumikizira.

Kuphatikiza pazida zomwe zili pamwambazi, zinthu zina zitha kuwonjezeredwa panthawi yopanga kutengera zofunikira.Mwachitsanzo, zomatira zitha kugwiritsidwa ntchito kulumikiza zigawo zosiyanasiyana za mabwalo osinthika osindikizidwa pamodzi. Zomatirazi zimatsimikizira mgwirizano wamphamvu komanso wodalirika, zomwe zimalola kuti dera likhalebe lokhazikika. Zomatira za silicone zimagwiritsidwa ntchito nthawi zambiri chifukwa cha kusinthasintha kwawo, kukana kutentha kwambiri, komanso zomangira zabwino kwambiri.

Ponseponse, zida zomwe zimagwiritsidwa ntchito popanga mabwalo osinthika osindikizidwa amasankhidwa mosamala kuti zitsimikizire kuti zimagwira bwino ntchito komanso kulimba.Kuphatikizika kwa polyimide ngati gawo lapansi, mkuwa wopangira madulidwe, zokutira zoteteza, zida zolimbikitsira zowonjezera mphamvu, ndi mapadi olumikizana ndi zigawo zimapanga mawonekedwe odalirika komanso osinthika osinthika osindikizidwa. Kuthekera kwa mabwalowa kuti agwirizane ndi machitidwe osiyanasiyana, kuphatikiza malo opindika ndi malo olimba, kumapangitsa kukhala kofunikira pazida zamakono zamakono.

Mwachidule, zida zosinthika zosindikizidwa zosindikizidwa monga polyimide, mkuwa, zokutira, zolimbitsa, zomatira, ndi mapepala ndizofunikira kwambiri popanga mabwalo amagetsi okhazikika komanso osinthika.Zidazi zimagwirira ntchito limodzi kuti zipereke malumikizano ofunikira amagetsi, chitetezo ndi mphamvu zamakina zomwe zimafunikira pazida zamakono zamakono. Pomwe ukadaulo ukupitilirabe kusinthika, zida zomwe zimagwiritsidwa ntchito popanga makina osindikizira osinthika zitha kusinthika, ndikupangitsa kugwiritsa ntchito mwanzeru.
