Iro rakadhindwa redunhu bhodhi rinoumbwa nendiro yepasi inodzivirira, waya yekubatanidza uye padhi yekuunganidza uye welding zvigadzirwa zvemagetsi, uye ine mabasa maviri eiyo conductive circuit uye insulating yepasi ndiro.Inogona kutsiva wiring yakaoma uye kuona kubatana kwemagetsi pakati pezvinhu zvakasiyana-siyana mudunhu.Haisi kungorerutsa kuungana uye welding yezvigadzirwa zvemagetsi, inoderedza kuwanda kwewaya nenzira yechinyakare, uye inoderedza zvakanyanya kusimba kwevashandi;iyo zvakare inoderedza iyo yakazara muchina Vhoriyamu, kuderedza chigadzirwa mutengo, uye kunatsiridza mhando uye kuvimbika kwemidziyo yemagetsi.Iyo yakadhindwa yedunhu bhodhi ine yakanaka chigadzirwa kuenderana, uye inogona kutora yakamisikidzwa dhizaini, iyo inobatsira pakuzadzikiswa kwemakanika uye otomatiki mukugadzira maitiro.Panguva imwecheteyo, iyo yese yakadhindwa yedunhu bhodhi iyo yakaunganidzwa uye yakagadziriswa inogona kushandiswa seyakazvimirira spare chikamu kufambisa kuchinjana uye kuchengetedza kwechigadzirwa chose.Parizvino, mabhodhi edunhu akadhindwa akashandiswa zvakanyanya mukugadzira zvigadzirwa zvemagetsi.

Mapuranga ekutanga akadhindwa edunhu akashandisa mapepa-based copper-clad mapuranga akadhindwa.Kubva pakabuda semiconductor transistors muma1950, kudiwa kwemabhodhi akadhindwa kwakakwira zvakanyanya.Kunyanya, kukurumidza kukurumidza uye kushandiswa kwakakura kwemaseketi akabatanidzwa akaita kuti huwandu hwemidziyo yemagetsi huve hudiki uye hudiki, uye kuwanda uye kuomerwa kweiyo wiring yedunhu yakawedzera uye yakakura, izvo zvinoda kuenderera mberi nekuvandudzwa kwemapuranga akadhindwa.Parizvino, zvakasiyana-siyana zvemapuranga akadhindwa akagadzirwa kubva kune rimwe-sided board kusvika kune maviri-sided board, multilayer board uye flexible board;chimiro uye mhando dzakagadziridzwawo kune yekupedzisira-yakakwirira density, miniaturization uye yakakwirira kuvimbika;nzira itsva dzekugadzira, zvigadzirwa zvekugadzira uye Bhodhi-kugadzira zvinhu uye maitiro ekugadzira bhodhi anoramba achibuda.Mumakore achangopfuura, akasiyana komputa-inobatsira dhizaini (CAD) yakadhindwa yedunhu bhodhi application software yakave yakakurumbira uye nekusimudzirwa muindasitiri iyi.Pakati pevagadziri vebhodhi vakadhindwa, kugadzirwa kwemuchina uye otomatiki kwatsiva zvachose mashandiro emaoko.

Origin

Mugadziri wePCB ndiAustria Paul Eisler (Paul Eisler), muna 1936, akatanga kushandisa bhodhi redunhu rakadhindwa muredhiyo.Muna 1943, vanhu vekuAmerica vainyanya kushandisa tekinoroji iyi kumaredhiyo emauto.Muna 1948, United States yakabvumira zviri pamutemo chigadzirwa ichi kuti chishandiswe mukutengesa.Kubva pakati pema1950, mabhodhi edunhu akadhindwa achangotanga kushandiswa zvakanyanya.Mabhodhi edunhu akadhindwa anoonekwa munenge mumidziyo yese yemagetsi.Kana paine zvikamu zvemagetsi mune chimwe chishandiso, zvese zvakaiswa paPCB dzehukuru hwakasiyana.Basa guru rePCB nderekubatanidza zvinhu zvakasiyana-siyana zvemagetsi kudunhu rakafanotemerwa uye kuita basa rekutumira relay.Ndiyo yakakosha yemagetsi yekubatanidza zvigadzirwa zvemagetsi uye inozivikanwa se "amai vezvigadzirwa zvemagetsi".
