Chiyambi cha PCB
The kusindikizidwa dera bolodi wapangidwa ndi insulating pansi mbale, chingwe cholumikizira ndi pad kusonkhanitsa ndi kuwotcherera zigawo zikuluzikulu zamagetsi, ndipo ali ndi ntchito ziwiri za dera conductive ndi insulating pansi mbale.Ikhoza m'malo mwa mawaya ovuta ndikuzindikira kugwirizana kwa magetsi pakati pa zigawo zosiyanasiyana za dera.Sizimangophweka kusonkhana ndi kuwotcherera zinthu zamagetsi, zimachepetsa ntchito ya mawaya mwachizoloŵezi, komanso zimachepetsa kwambiri mphamvu ya ogwira ntchito;imachepetsanso kuchuluka kwa makina onse, kuchepetsa mtengo wazinthu, ndikuwongolera luso ndi kudalirika kwa zida zamagetsi.Bolodi yosindikizidwa ili ndi kusasinthika kwazinthu zabwino, ndipo imatha kutengera mapangidwe okhazikika, omwe amathandizira kukwaniritsidwa kwa makina ndi makina popanga.Panthawi imodzimodziyo, bolodi lonse losindikizidwa losindikizidwa lomwe lasonkhanitsidwa ndikusinthidwa lingagwiritsidwe ntchito ngati gawo lodziyimira palokha kuti lithandizire kusinthana ndi kukonza zinthu zonse.Pakalipano, matabwa osindikizira osindikizira akhala akugwiritsidwa ntchito kwambiri popanga zinthu zamagetsi.
Mabokosi osindikizira oyambirira ankagwiritsa ntchito mapepala opangidwa ndi mapepala opangidwa ndi mkuwa.Chiyambireni ma semiconductor transistors mu 1950s, kufunikira kwa ma board osindikizidwa kwakwera kwambiri.Makamaka, kukula kwachangu komanso kugwiritsa ntchito mabwalo ophatikizika ophatikizika kwapangitsa kuti kuchuluka kwa zida zamagetsi kukhala zazing'ono komanso zazing'ono, ndipo kachulukidwe ndi kuvutikira kwa mawaya ozungulira akukulirakulira, zomwe zimafunikira kusinthidwa kosalekeza kwa matabwa osindikizidwa.Pakalipano, mitundu yosiyanasiyana ya matabwa osindikizidwa yapangidwa kuchokera ku matabwa a mbali imodzi kupita ku matabwa awiri, matabwa a multilayer ndi matabwa osinthasintha;kapangidwe ndi khalidwe zapanganso kuti ultra-high kachulukidwe, miniaturization ndi mkulu kudalirika;njira zatsopano zopangira, zopangira mapangidwe ndi zida zopangira Board ndi njira zopangira matabwa zikupitiliza kuwonekera.M'zaka zaposachedwa, mapulogalamu osiyanasiyana othandizidwa ndi makompyuta (CAD) adatchuka komanso kukwezedwa pamsika.Pakati pa opanga ma board apadera, kupanga makina ndi makina alowa m'malo mwa ntchito zamanja.
Chiyambi
Wopanga PCB ndi waku Austria Paul Eisler (Paul Eisler), mu 1936, adagwiritsa ntchito koyamba gulu losindikizidwa pawailesi.Mu 1943, anthu a ku America ankagwiritsa ntchito kwambiri teknolojiyi pawailesi yankhondo.Mu 1948, dziko la United States linavomereza mwalamulo kuti zinthu zimenezi zigwiritsidwe ntchito pamalonda.Kuyambira pakati pa zaka za m'ma 1950, matabwa a dera osindikizidwa angoyamba kugwiritsidwa ntchito kwambiri.Mabokosi osindikizidwa amawonekera pafupifupi pazida zilizonse zamagetsi.Ngati pazida zinazake muli zida zamagetsi, zonse zimayikidwa pa PCB za makulidwe osiyanasiyana.Ntchito yayikulu ya PCB ndikulumikiza zida zosiyanasiyana zamagetsi kudera lodziwikiratu ndikugwira ntchito yotumizirana mauthenga.Ndiko kulumikizana kofunikira pamagetsi pamagetsi amagetsi ndipo amadziwika kuti "amayi azinthu zamagetsi".
