PCB Kulumikizana mumapangidwe onse a PCB ndikofunikira kwambiri, momwe mungapangire zingwe zolimba komanso zosavuta, ndikupangitsa kuti zingwe za PCB ziwoneke kwambiri, ndikofunikira kuphunzira ndikuphunzira. Zosanjidwa mbali 7 zomwe ziyenera kumvetsera mu waya wa PCB, bwerani mudzayang’ane ndikudzaza mipata!

Momwe mungapangire mapangidwe anu a PCB kuti achite bwino

1.Kukonza nthaka yofananira kwa dera la digito ndi dera la analog

Ma PCBS ambiri salinso magwiridwe antchito amodzi (digito kapena analogi), koma ndi kuphatikiza kwama digito ndi ma analog. Chifukwa chake, tikamalumikizana, tifunika kuganizira zosokoneza pakati pawo, makamaka kusokonekera kwa phokoso kumtunda. Kukhazikika kwa ma circuits apamwamba kwambiri a digito, ma circuits a analog, waya wama siginecha, mizere yayitali kwambiri yazizindikiro kutali kwambiri ndi zida zodziwika bwino za analog, chifukwa nthaka, kusunthira PCB kudziko lakunja ndi mfundo imodzi yokha, choncho ziyenera khalani mkati mwa kukonza kwa PCB, nkhungu ili ndi vuto, ndipo mkati mwa mbaleyo kupita ku digito ndi analog kwenikweni imagawanika pakati pawo, Pokhapokha mu PCB ndi mawonekedwe akunja olumikizirana (monga pulagi, ndi zina zambiri). Pali kulumikizana kwakanthawi pakati pa digito ndi nthaka ya analog. Dziwani kuti pali malo amodzi olumikizira. Palinso zosavomerezeka pa PCB, kutengera kapangidwe kake.

2. Chizindikiro chimayikidwa pamizere yamagetsi (pansi)

Mu zingwe zingapo za PCB, chifukwa palibe mzere womaliza womwe watsalira pamzere wazizindikiro, kenako ndikuwonjezera zigawo zomwe zingapangitse zinyalala kuonjezeranso kupanga kuchuluka kwa ntchito, mtengo udawonjezeranso moyenera, kuti athetse kutsutsana uku, mutha kulingalira za zingwe zamagetsi zamagetsi (pansi). Dera lamagetsi liyenera kuganiziridwa koyamba, ndikupanga kwachiwiri. Chifukwa ndibwino kuti mapangidwe asasunthike.

3. Kusintha kwa miyendo yolumikizira mdera lalikulu

M’dera lalikulu la pansi (magetsi), miyendo yazinthu wamba imalumikizidwa nayo. Kukonzekera kwa miyendo yolumikizira kuyenera kuganiziridwa mozama. Potengera magwiridwe antchito amagetsi, ziyangoyango zamiyendo yolumikizidwa ndizolumikizana kwathunthu ndi pamwamba pamkuwa, koma pali zovuta zina zobisika pamsonkhano wowotcherera wa zinthu, monga: (1) kuwotcherera kumafunikira chotenthetsera magetsi chachikulu. (2) Easy kuyambitsa pafupifupi mafupa solder. Chifukwa chake, poganizira momwe magetsi amagwirira ntchito ndi momwe amafunira, pangani mtanda wowotcherera, wotchedwa chishango chotentha, chomwe chimadziwika kuti Thermal, kuti kuthekera kwa malo owotcherera chifukwa chakutentha kwakukulu kwa gawolo panthawi yowotcherera kumatha kuchepetsedwa. Mwendo wamagetsi (pansi) wama multilayer amachitiranso chimodzimodzi.

4. Udindo wa makina ochezera pa intaneti

M’makina ambiri a CAD, kulumikizana kumatsimikizika ndi makina amtaneti. Gululi ndilolimba kwambiri, njirayo yawonjezeka, koma sitepe ndi yaying’ono kwambiri, kuchuluka kwa deta ya gawo la graph ndilokulirapo, zomwe mosakayikira zidzakhala ndizofunikira kwambiri posungira zida, komanso zimakhudza kwambiri kuthamanga kwa kompyuta kwamagetsi apakompyuta. Njira zina ndizosavomerezeka, monga zomwe zimakhala ndi mapadi amiyendo yamagawo kapena pokweza mabowo, kukhoma mabowo, ndi zina zambiri. Grid yocheperako komanso njira zochepa kwambiri zimakhudza kwambiri magawidwewo. Chifukwa chake, payenera kukhala dongosolo loyenera lothandizira waya. Miyendo yazinthu zophatikizika imakhala 0.1 inchi (2.54mm) kupatukana, chifukwa chake maziko a grid nthawi zambiri amakhala inchi 0.1 (2.54mm) kapena zochulukitsa zosachepera 0.1 inchi (mwachitsanzo 0.05 inchi, 0.025 inchi, 0.02 inchi, ndi zina zambiri) .
