Malinga ndi chithunzi chosindikizira, chofanizira chitha kuchitidwa ndipo PCB itha kupangidwa ndikutumiza fayilo ya Gerber / Grop. Kaya kapangidwe kakuti, akatswiri amainjiniya ayenera kumvetsetsa momwe mabwalo (ndi zigawo zamagetsi) amayenera kuyikidwa ndi momwe amagwirira ntchito. Kwa opanga zamagetsi zamagetsi, kupeza zida zoyenera mapulogalamu za PCB zitha kukhala ntchito yovuta. Zida Zapakati pa Pulogalamu Yabwino pa PCB imodzi silingagwire bwino ena. Akatswiri amafuna zida zopangira matayala omwe ali owoneka bwino, ali ndi zinthu zothandiza, ndizokhazikika zokwanira kuchepetsa chiopsezo, ndikukhala ndi laibulale yobowola yomwe imawapangitsa kukhala oyenera polojekiti ambiri.

Vuto la Hardware

Pa ntchito za iot, kuphatikiza ndikofunikira pakuchita ndi kudalirika, ndipo kuphatikiza kwa zinthu zomwe zimapangitsa kuti zikhale ma PCB kumafunikira kuti agwiritse ntchito zinthu zosiyanasiyana zamagetsi komanso makina opanga mapangidwe. Makamaka monga zinthu zomwe zimapangitsa zikupitirirabe, kuwombeza kwamagetsi pa PCB ikukavuta kwambiri. Nthawi yomweyo, zofuna za ntchito zikukwera. Kuti mukwaniritse ntchito yopanga mapangidwe, mayankho a kutentha, machitidwe a zigawo zamagetsi pa bolodi, ndipo kuchuluka kwa mawotchi kumafunikira magwiridwe antchito komanso kudalirika kwa dongosololi.

PCB iyenera kukhala yokhayokha kuti mutsimikizire chitetezo. Mabwalo afupiafupi amaletsedwa poteteza kamtengo wa mkuwa womwe umayikidwa pa bolodi kuti apange njira yamagetsi. Poyerekeza ndi zotsika mtengo monga pepala lomata zomata (srbp, fr-1, fr-2), makamaka kuti azitha kusunga zambiri chifukwa cha zinthu zina, komanso kuti zimamwa madzi ena kuposa zida zina. The fr-4 imagwiritsidwa ntchito kwambiri nyumba zomaliza komanso zida za mafakitale komanso zida zankhondo. Imagwirizana ndi mawu apamwamba kwambiri (omwe ali ndi vuto lalikulu kapena ulv).

Komabe, Fr-4 ngati pcb gawo la PCB limayang'anizana ndi malire angapo, omwe tsitsani mankhwala omwe amagwiritsidwa ntchito popanga. Makamaka, zomwe zimakonda kupangidwa ndi zophatikizika (thovu) ndi mitsinje (kutalika kwa mitsinje), komanso kuphatikizika kwa galasi. Zofooka izi zimatha kuyambitsa mphamvu wamba komanso kuwonongeka kwa PCB yovuta. Magalasi atsopano a epoxy amathetsa mavutowa.

Zida zina zogwiritsidwa ntchito zimaphatikizapo chiberekero cha Polymide Zinthu zofunika kuziganizira mukasankha zinthu zam'madzi (zimaphatikizaponso kuphatikiza kwa mafuta ophulika (CTE), kutentha kwagalasi (TG), kutentha kwa matenthedwe, komanso kuthamanga kwamakina.

Asitikali / Aerospace PCBS amafunikira malingaliro apadera potengera masheya ndi 100% poyesa (DFT) Kupeza. Mar-st dra-883 okhazikika amakhazikitsa njira ndi njira zoyeserera zida za microelectic zoyenera zankhondo ndi Ansespace Miystems, kupanga njira zoyeserera, komanso zowongolera zina zonse. Ntchito zosiyanasiyana za zida zotere.

Kuphatikiza pa kukumana ndi mfundo zosiyanasiyana, kapangidwe ka zamagetsi zamagetsi ziyenera kutsata malamulo angapo, monga mayeso a AEC-Q100 ndi magetsi ophatikizika. Zotsatira za crostalk zitha kusokoneza chitetezo chamagalimoto. Kuti muchepetse izi, opanga a PCB ayenera kutchula mtunda pakati pa chingwe ndi chingwe. Kupanga ndi kukhazikika kumatsimikizika ndi zida zamapulogalamu omwe amangoyang'ana zokhazokha zomwe zimafunikira kusintha kwa zinthu zina kuti zithetse kusokoneza dongosolo.

Zolemba:

Kulowererapo kwa chizungu sikuwopseza mtundu. PCB mgalimoto ili pachiwopsezo ndi phokoso, zomwe zimalumikizana ndi thupi m'njira zovuta kuyika zomwe sizikufuna padera. Spikes spikes ndi kusinthasintha kwa magetsi omwe amayambitsidwa ndi makina oyatsira magalimoto amatha kukankhira zinthu zomwe sangathe kulolera.

Vuto la mapulogalamu

Zida zamakono za PCB za PCB ziyenera kukhala ndi magwiritsidwe ntchito angapo ogwira ntchito kuti akwaniritse zofunikira za opanga. Kusankha chida choyenera kuyenera kulingalira koyamba mu kapangidwe ka PCB ndipo sikuyenera kunyalanyazidwa. Zogulitsa zochokera ku zojambula zopangira, Orcad, ndi Altuum ndi ena mwa zida zamakono za PCB.

Wopanga Altiamu

Gulu la Agaramium ndi imodzi mwazithunzi zoyeserera za PCB pamsika lero. Ndi ntchito yongomaliza yomaliza, thandizo la kutalika kwa mzere ndi 3d. Wopanga gulu

Platiformafformatic 'PCB ya alangizi imayankha zovuta zazikulu zomwe akumana nazo. Kukhazikika kwamphamvu ndi matupi owirikiza; Ndi electromachanical kukhathamiritsa. Gawo lofunikira papulatifomu ndi njira yofunika kwambiri yopanga ma ratery, yomwe imapatsa opanga njira yolumikizira yokhayo / yothandizirana, ndikupanga mtundu womwewo monga kuvundira, koma munthawi yochepa.

Orcad PCB mkonzi

Orcad PCB mkonzi ndi malo omwe amapezeka kuti azipanga ma board aliwonse aukadaulo, kuchokera ku zosavuta kwa zovuta. Chifukwa cha chiwopsezo chake chowona ku CCB Stud Stuments's PCB, Thcad PCB imathandizira kukulitsa magulu opanga ndipo amatha kuthana ndi mawonekedwe owoneka bwino, ndi zina mwa mafayilo

Fayilo ya Gerber

Mtundu wa mafakitale wa mafayilo a Gerber amagwiritsidwa ntchito kufotokozera za kapangidwe ka PCB. Munjira zambiri Ndi mawonekedwe a fayilo yaying'ono yolembedwa mu chilankhulo chosakanikirana. Mafayilo awa amapangidwa ndi pulogalamu ya breamu yadera ndikutumiza ku wopanga PCB kupita ku Cam Pulogalamu ya Cam.

Kuphatikizidwa ndi magetsi bwino m'magalimoto ndipo njira zina zovuta zimapereka malingaliro ofunikira onse ndi mapulogalamu. Akatswiri amafunitsitsa kuchepetsa kuchuluka kwa kapangidwe kake ndi nthawi yachitukuko, komwe kumakhala ndi zabwino kwa opanga zomwe akupanga.
