PCB malingaliro apangidwe a modular

Poyang’anizana ndi zinthu zamagetsi zomwe zimakhala ndi nsanja zambiri zophatikizika za hardware ndi machitidwe ovuta kwambiri, kuganiza modula kuyenera kutengedwa kwa masanjidwe a PCB. Njira zopangira ma modular ndi zokhazikika ziyenera kugwiritsidwa ntchito pamapangidwe aukadaulo a hardware ndi ma waya a PCB. Monga mainjiniya a hardware, pamalingaliro omvetsetsa kamangidwe kake kachitidwe kake, amayenera kuphatikizira mwachidziwitso lingaliro lopanga ma modular mujambula ndi ma waya a PCB, ndikukonzekera lingaliro loyambira la masanjidwe a PCB molingana ndi momwe PCB ilili.

Module ya PCB yowonera mwachidule mawonekedwe apangidwe

Kuyika kwa zinthu zokhazikika

Kuyika kwa zigawo zokhazikika kumafanana ndi kuyika mabowo osasunthika, komanso kumayang’anitsitsa malo enieni. Izi zimayikidwa makamaka molingana ndi kapangidwe kake. Pakatikati ndi kuphatikizira zowonera za silika zamagulu ndi zomangira, monga zikuwonekera pa Chithunzi 9-6. Zinthu zokhazikika pa bolodi zitayikidwa, njira yoyendetsera ma siginecha ya bolodi yonse imatha kuphatikizidwa molingana ndi mfundo yakuyandikira kwa mizere yowuluka komanso mfundo yoyambira chizindikiro.

Zojambulajambula ndi Zokonda pa PCB

Pofuna kuthandizira kufufuza kwa zigawo, chithunzi cha schematic ndi PCB chiyenera kukhala chofanana, kuti awiriwa athe kupanga mapu, omwe amatchedwa kuyanjana. Pogwiritsa ntchito masanjidwe olumikizana, zida zitha kukhazikitsidwa mwachangu, motero kuchepetsa nthawi yopangira ndikuwongolera magwiridwe antchito.

(1) Kuti mukwaniritse kulumikizana pakati pa chithunzi chojambula ndi PCB awiriawiri, ndikofunikira kuti mupereke lamulo la menyu “Tool-Cross kusankha mode” pamawonekedwe onse azithunzi ndi mawonekedwe a PCB kuti mutsegule mawonekedwe osankhidwa, monga kuwonetsedwa mu Chithunzi 9-7.

(2) Monga momwe FIG. 9-8, zitha kuwoneka kuti chigawo chikasankhidwa pazithunzi zamakonzedwe, gawo lofananira pa PCB lidzasankhidwa mogwirizana; Mosiyana ndi izi, gawo likasankhidwa pa PCB, gawo lofananira pa schema imasankhidwanso.

Kamangidwe modular

Pepala ili likuwonetsa ntchito ya kakonzedwe kagawo, ndiko kuti, kakonzedwe ka zigawo m’dera lamakona anayi, lomwe lingaphatikizidwe ndi kulumikizana kwa zigawo pagawo loyambirira la masanjidwewo kuti alekanitse mosavuta gulu lazinthu zachisokonezo ndi ma module ndi malo. iwo m’dera linalake.

(1) Sankhani zigawo zonse za gawo limodzi pazithunzithunzi, ndiye zigawo zomwe zikugwirizana ndi chithunzi cha PCB zidzasankhidwa.

(2) Perekani lamulo la menyu “Zida-Zipangizo-Zokonzekera m’dera lamakona anayi”.

(3) Sankhani malo omwe ali opanda kanthu pa PCB, ndiye zigawo za gawo la ntchito zidzakonzedwa m’bokosi losankhidwa, monga momwe tawonetsera pa Chithunzi 9-9. Ndi ntchitoyi, ma modules onse ogwira ntchito pazithunzithunzi amatha kugawidwa m’mabwalo mwamsanga.

Masanjidwe a modular ndi masanjidwe olumikizana amayendera limodzi. Pogwiritsa ntchito masanjidwe olumikizana, sankhani zigawo zonse za gawoli pazithunzi zachimangidwe ndikuzikonza chimodzi ndi chimodzi pa PCB. Kenako, mutha kukonzanso masanjidwe a IC, resistor ndi diode. Uwu ndiye masanjidwe okhazikika, monga momwe tawonetsera pa Chithunzi 9-10.

M’mawonekedwe a modular, mutha kuyendetsa lamulo la Vertical Partition kuti mugawanitse mawonekedwe osinthira azithunzi ndi mawonekedwe a PCB, monga momwe zasonyezedwera pa Chithunzi 9-11, kuti mupange masanjidwe mwachangu powonera mawonedwe.
