Mu kapangidwe ka PCB, madera a zinthuzi ndi ofunikira, omwe amawonetsa kuti ndi owoneka bwino komanso kutalika kwake ndi kuchuluka kwa waya, ndipo kumakhudzanso kudalirika kwa makina onse.
Gulu labwino
Zofunikira za PCB
1
2, ikani malo a gululo mpaka 25mil, itha kusaina kudzera mu gridi point, yofanana; Njira yolumikizidwa ndi yayikulu isanachitike (zida zazikulu ndi zida zazikulu zimagwiritsidwa ntchito), ndipo mawonekedwe ophatikizika ndi Center, monga akuwonetsera mu chithunzi chotsatira
3, kukumana ndi malo oletsedwa madera, kapangidwe ndi chipangizo chapadera, malo oletsedwa m'deralo.
① Chithunzi 1 (kumanzere) pansipa: Malo oyenera kutalika, olembedwa momveka bwino mu makina opangira makina kapena chizindikiro, chowoneka bwino pamtunda.
.
- Masanjidwe a kapangidwe kake ndi zida zapadera amatha kukhazikitsidwa molondola ndi magwiridwe antchito kapena magwiridwe a chimango chakunja kapena mzere wa zigawo zikuluzikulu.
4. Jambulani mzere wa ovomerezeka 40mil, ndikuwunikiranso mgwirizano pakati pa ma module a ma module ndi ma module kudzera pazomwe zili pamwambapa, monga zikuwonekera m'munsimu.
5, Masanjidwe ayenera kuganizira njira yomwe imachoka pamzere wamagetsi, sayenera kukhala wolimba kwambiri, kudzera pakukonzekera kupeza komwe mphamvu imachokerako komwe mungapite, sakani mtengo wamagetsi
6, zigawo za mafuta (monga ma car electolytic, makristal oscillators) makonzedwe ayenera kukhala kutali ndi magetsi ndi zida zina zapamwamba, monga momwe mungathere pompopompo
7, kukakumana ndi kusiyanasiyana kolunjika, malo onse a board, bolodi lonse
Zizindikiro zapamwamba komanso zamakono zomwe zimapatukana kwathunthu kuchokera ku zizindikiro zofooka zazing'ono ndi ma volts ochepa. Magawo apamwamba kwambiri okhala ndi zigawo zonse popanda mkuwa. Mtunda wowoneka bwino pakati pa zigawo zamagetsi amafufuzidwa molingana ndi tebulo lokhazikika
Chizindikiro cha Analog chimasiyanitsidwa ndi chizindikiritso cha digito ndi kukula kwa 20mil, ndipo analog ndi rf amakonzedwa muzofunikira molingana ndi kapangidwe kake.
Chizindikiro chambiri chambiri chimasiyanitsidwa ndi chizindikiro chochepa kwambiri, mtunda wopatukana ndi 3mm, ndipo khola la mtanda silingatsimikizidwe
Kapangidwe ka zida zazikulu zokhala ndi makhrillal oscillator ndi woyendetsa ma shope amayenera kukhala kutali ndi mawonekedwe adera, osakhala m'mphepete mwa bolodi, ndipo osachepera 10mmm kuchokera m'mphepete mwa board. Mliri wonyezimira komanso wozungulira wa crystal uyenera kuyikidwa pafupi ndi chip, adayikidwa mu chosanjikiza chomwecho, osalipira mabowo, ndikusunga malo
Gawo lofananalo limatengera "symmetrical" wamba "
Pambuyo pa kapangidwe ka PCB, tiyenera kuwunika ndikuwunika kuti izi zitheke.
