Kuwulula zinthu zomwe zimakhudza kukwera kwamitengo kwa ma rigid-flex board

Tsegulani:

Takulandilani kubulogu yovomerezeka ya Capel, kampani yodziwika bwino mumakampani opanga madera omwe ali ndi zaka zopitilira 15.M'nkhaniyi, tifufuza za dziko lovuta la ma PCB osinthasintha ndikuwona zomwe zimapangitsa kuti mitengo yawo ikhale yokwera.Rigid-flex board ndikupita patsogolo kwapang'onopang'ono pama board osindikizidwa, omwe amaphatikiza ubwino wa matabwa okhwima ndi matabwa osinthika.Tiyeni tiwone mwatsatanetsatane zifukwa zomwe amapangira mitengo yamtengo wapatali ndikumvetsetsa tanthauzo lake.

1. Kupanga ndi kupanga zovuta:

Ma board olimba osinthika amakhala ndi luso lopanga komanso zinthu zosinthika komanso zokhazikika, ndipo mapangidwe awo ndi kupanga kwake ndizovuta kwambiri kuposa ma PCB achikhalidwe.Ma board awa amafunikira njira zaumisiri zovuta, monga kubowola laser ndi kuwongolera kowongolera, kuti apange mabwalo ovuta omwe amathandizira.Kuwonjezeka kwa zovuta kumafuna nthawi yowonjezera, khama, ndi zothandizira, zomwe zimapangitsa kuti pakhale ndalama zambiri zopangira, zomwe zimamasulira kukhala mitengo yapamwamba.

2. Zida zopangira akatswiri:

Chinthu chinanso chofunikira chomwe chimapangitsa kuti mitengo ichuluke pama board okhazikika ndi kufunikira kwa zida ndi njira zopangira akatswiri.Chifukwa cha mawonekedwe awo apadera, njira zachikhalidwe zopangira PCB sizoyenera nthawi zonse ma PCB okhazikika.Gwiritsani ntchito makina apadera kuti mupange kusinthasintha, zida zolimba komanso kulumikizana kuti zitheke kupanga zovuta komanso ntchito zambiri.Pali ndalama zowonjezera zomwe zimagwirizanitsidwa ndi kugwiritsa ntchito makina apaderawa, kotero kuti mitengo yake yokwera ndiyoyenera.

3. Kapangidwe kazinthu:

Kuphatikiza kwa zinthu zolimba komanso zosinthika mu PCB zokhazikika zimafunikira zida zosankhidwa mosamala.Zida izi, monga polyimide kapena liquid photoimageable solder mask (LPI), ziyenera kupirira zinthu zosiyanasiyana, kuphatikizapo kusinthasintha kwa kutentha, kupsinjika maganizo ndi kayendetsedwe kake.Kugwiritsa ntchito zida zapamwamba, zodalirika kuti zitsimikizire kulimba ndi magwiridwe antchito zimakulitsa mtengo wamba, zomwe zimapangitsa kuti mitengo ikhale yokwera pama board okhazikika.

4. Kuyesa ndi kuyesa nthawi yambiri:

Prototyping ndi kuyezetsa ndi magawo ofunikira pakukula kulikonse kwa board board.Komabe, zikafika pa ma PCB okhwima, magawowa amakhala owononga nthawi komanso ovuta.Chifukwa cha kapangidwe kawo kamitundu yambiri komanso zofunikira zapadera zamapangidwe, ma board okhazikika amafunikira kuyesedwa koyenera kuti atsimikizire kugwira ntchito, kudalirika komanso kulimba.Chigawo chilichonse ndi mfundo yolumikizira ziyenera kutsimikiziridwa mosamala, zomwe zimawonjezera mtengo wonse wopanga ndipo motero mtengo wa matabwawa.

5. Chepetsani kupanga ndi kuchepetsa ogulitsa:

Poyerekeza ndi ma PCB achikhalidwe, ma board okhazikika amakhala ndi zotulutsa zochepa chifukwa cha ukadaulo wawo wocheperako komanso kugwiritsa ntchito kwawo.Kutsika kwamitengo kungapangitse mitengo yokwera chifukwa chuma sichinakwaniritsidwebe.Kuphatikiza apo, pali ogulitsa ochepa omwe amagwira ntchito yopanga ma rigid-flex board, omwe amalepheretsa mpikisano wamsika.Kuchepa kophatikizika kophatikizika ndi kufunikira kwakukulu kwapangitsa mitengo yamitengo yama boardboard awa.

6. Onjezani kapangidwe kake ndi chithandizo chaukadaulo:

Poganizira zovuta za ma PCB okhazikika, makasitomala nthawi zambiri amafunikira mamangidwe owonjezera ndi chithandizo chaumisiri kuchokera kwa opanga panthawi yachitukuko.Popeza matabwawa amafunikira malingaliro apadera a mapangidwe ndi njira zopangira, kutenga nawo mbali kwa akatswiri aluso kumawonjezera mtengo wonse.Kuwonjezeka kwapangidwe ndi kuthandizira kwaumisiri kwa ma PCB okhazikika-osinthasintha potsirizira pake kumawonekera pamitengo yawo yapamwamba, kuonetsetsa kuti makasitomala amalandira ukadaulo womwe amafunikira kuti akwaniritse ntchito yabwino.

Powombetsa mkota:

Mwachidule, mtengo wokwera wa ma PCB okhazikika-osinthika umachitika chifukwa cha zinthu zingapo, kuphatikiza zovuta za kapangidwe kawo ndi kupanga, kugwiritsa ntchito zida zapadera, zida zosankhidwa mosamala, kuyesa kwanthawi yayitali ndi kuyesa, kuchuluka kwa kupanga kochepa, ndi zina zowonjezera. mtengo wa.mtengo.Design ndi mainjiniya thandizo.Ma board a Rigid-flex amayimira matekinoloje otsogola omwe amayendetsa zatsopano m'mafakitale, koma mitengo yawo yokwera ndi umboni wazovuta zomwe zimafunikira kuti apange.Monga mtsogoleri wamakampani opanga ma boardboard, Capel amamvetsetsa zovutazi ndipo akudzipereka kupereka ma board apamwamba okhwima kuti akwaniritse zosowa za makasitomala athu.
