Kumvetsetsa ukadaulo wa rigid-flex circuit board bonding

Tsegulani:

Mu positi iyi yabulogu, tisanthula mwatsatanetsatane momwe zigawo za gulu lozungulira lokhazikika zimalumikizidwa, ndikuwunika njira zosiyanasiyana zomwe zimagwiritsidwa ntchito pochita izi.

Ma board a Rigid-flex circuit ndi otchuka m'mafakitale osiyanasiyana kuphatikiza zakuthambo, zamankhwala, ndi zamagetsi zamagetsi. Ma board awa ndi apadera chifukwa amaphatikiza zozungulira zosinthika ndi zigawo zolimba, zomwe zimapereka kukhazikika komanso kusinthasintha. Chimodzi mwa zinthu zofunika kwambiri zomwe zimatsimikizira kugwira ntchito ndi kudalirika kwa matabwa okhwima-flex ndi teknoloji yogwirizanitsa yomwe imagwiritsidwa ntchito kugwirizanitsa zigawo zosiyanasiyana.

1. Tekinoloje yolumikizirana:

Ukadaulo womatira womata umagwiritsidwa ntchito kwambiri popanga ma board ozungulira okhazikika. Zimaphatikizapo kugwiritsa ntchito zomatira zapadera zomwe zimakhala ndi mankhwala ochiritsa kutentha. Zomatirazi zimagwiritsidwa ntchito kulumikiza zigawo zosinthika ku magawo olimba a matabwa ozungulira. Zomatira sizimangopereka chithandizo chokhazikika komanso zimatsimikizira kugwirizana kwa magetsi pakati pa zigawozo.

Panthawi yopangira, zomatira zimagwiritsidwa ntchito mwadongosolo ndipo zigawozo zimagwirizana bwino musanakhale laminated pamodzi pansi pa kutentha ndi kupanikizika. Izi zimatsimikizira mgwirizano wamphamvu pakati pa zigawozo, zomwe zimapangitsa kuti pakhale bolodi lozungulira lokhazikika lomwe lili ndi makina abwino kwambiri komanso magetsi.

2. Ukadaulo wa Surface Mount (SMT):

Njira ina yotchuka yomangirira zigawo za bolodi lokhazikika ndikugwiritsa ntchito ukadaulo wapamwamba kwambiri (SMT). SMT imaphatikizapo kuyika zida zapamtunda molunjika pagawo lolimba la bolodi lozungulira ndikugulitsa zigawozi pamapadi. Tekinolojeyi imapereka njira yodalirika komanso yodalirika yolumikizira zigawozo ndikuonetsetsa kuti magetsi akugwirizana pakati pawo.

Mu SMT, zigawo zolimba komanso zosinthika zimapangidwira ndi ma vias ofananira ndi ma pads kuti athandizire kugulitsa. Ikani phala la solder pamalo a pad ndikuyika chigawocho molondola. Bwalo lozungulira limayikidwa kudzera mu njira ya reflow soldering, pomwe phala la solder limasungunuka ndikugwirizanitsa zigawozo, ndikupanga mgwirizano wamphamvu.

3. Kupyolera m'mabowo:

Kuti akwaniritse mphamvu zamakina komanso kulumikizana kwamagetsi, ma board ozungulira okhazikika nthawi zambiri amagwiritsa ntchito pobowo. Njirayi imaphatikizapo kubowola mabowo m'magawo ndikugwiritsa ntchito ma conductive mkati mwa mabowowo. Chinthu chochititsa chidwi (nthawi zambiri mkuwa) chimapangidwa ndi electroplated pamakoma a dzenje, kuonetsetsa kuti pali mgwirizano wamphamvu ndi magetsi pakati pa zigawozo.

Kupyolera m'mabowo kumapereka chithandizo chowonjezera ku matabwa okhazikika komanso kuchepetsa chiopsezo cha delamination kapena kulephera m'madera omwe ali ndi nkhawa kwambiri. Kuti mupeze zotsatira zabwino, mabowo obowola ayenera kuyikidwa mosamala kuti agwirizane ndi ma vias ndi mapepala pamagawo osiyanasiyana kuti akwaniritse kulumikizana kotetezeka.

Pomaliza:

Ukadaulo womatira womwe umagwiritsidwa ntchito m'mabwalo ozungulira a rigid-flex umagwira ntchito yofunika kwambiri pakuwonetsetsa kukhulupirika kwawo komanso magwiridwe antchito amagetsi. Kumatira, ukadaulo wokwera pamwamba komanso kuyika-bowo ndi njira zomwe zimagwiritsidwa ntchito kwambiri kuti zilumikize zigawo zosiyanasiyana. Ukadaulo uliwonse uli ndi zabwino zake ndipo umasankhidwa potengera zofunikira za kapangidwe ka PCB ndikugwiritsa ntchito.

Pomvetsetsa njira zomangira zomwe zimagwiritsidwa ntchito m'mabwalo ozungulira okhazikika, opanga ndi opanga amatha kupanga misonkhano yamagetsi yolimba komanso yodalirika. Ma board ozungulirawa otsogola amakwaniritsa zofunikira zaukadaulo wamakono, kulola kukhazikitsidwa kwamagetsi osinthika komanso olimba m'mafakitale osiyanasiyana.
