Ngaphambi kokufika kweebhodi zeesekethe eziprintiweyo, ukudibanisa phakathi kwamacandelo e-elektroniki kuxhomekeke ekudibaneni ngokuthe ngqo kweengcingo ukwenza isiphaluka esipheleleyo.Kumaxesha angoku, iiphaneli zesekethe zikhona kuphela njengezixhobo zovavanyo ezisebenzayo, kwaye iibhodi zesekethe eziprintiweyo ziye zaba yeyona ndawo ibalaseleyo kwishishini le-elektroniki.
Ekuqaleni kwenkulungwane yama-20, ukuze kwenziwe lula ukuveliswa koomatshini be-elektroniki, ukunciphisa iingcingo phakathi kwamalungu e-elektroniki, nokunciphisa iindleko zokuvelisa, abantu baqalisa ukufunda indlela yokutshintsha iingcingo ngokushicilela.Kwiminyaka engamashumi amathathu edlulileyo, iinjineli ziye zaphakamisa ngokuqhubekayo ukongeza ii-conductor zentsimbi kwi-insulating substrates ze-wiring.Eyona mpumelelo yayingowe-1925, xa uCharles Ducas waseUnited States washicilela iipatheni zesekethe kwi-insulating substrates, waza emva koko waseka ngempumelelo iiconductors zocingo nge-electroplating. Kude kwangowe-1936, uPaul Eisler waseOstriya (uPaul Eisler) wapapasha iteknoloji yefoil eUnited Kingdom. wasebenzisa ibhodi yesekethe eprintiweyo kwisixhobo sikanomathotholo;eJapan, uMiyamoto Kisuke wasebenzisa indlela yokutshiza efakwe kwi-wiring "メ タリ コ ン" Indlela yocingo ngendlela (i-Patent No. 119384)" ifake isicelo ngempumelelo kwi-patent.Phakathi kwezi zibini, indlela kaPaul Eisler yeyona nto ifana neebhodi zeesekethe eziprintiweyo zanamhlanje.Le ndlela ibizwa ngokuba yi-subtraction, esusa isinyithi esingeyomfuneko;ngelixa uCharles Ducas kunye noMiyamoto Kisuke indlela yokongeza kuphela efunekayo I-wiring ibizwa ngokuba yindlela yokudibanisa.Nangona kunjalo, ngenxa yokushisa okuphezulu kwamacandelo e-elektroniki ngelo xesha, ii-substrates ezimbini kwakunzima ukuzisebenzisa kunye, ngoko ke kwakungekho sicelo esisebenzayo esisemthethweni, kodwa kwakhona kwenza iteknoloji yesekethe eprintiweyo iqhube phambili.
Phuhlisa
Kule minyaka ilishumi idlulileyo, iBhodi yeSekethe eShicileleyo yelizwe lam (PCB) ishishini lokuvelisa likhule ngokukhawuleza, kwaye ixabiso layo lilonke lemveliso kunye nesiphumo esipheleleyo zombini zikumgangatho wokuqala emhlabeni.Ngenxa yophuhliso olukhawulezayo lweemveliso ze-elektroniki, imfazwe yexabiso iye yatshintsha isakhiwo sekhonkco lokubonelela.I-China inezo zombini ukuhanjiswa kwamashishini, iindleko kunye neenzuzo zemarike, kwaye iye yaba yeyona nto ibalulekileyo eprintiweyo isiseko sebhodi yesekethe emhlabeni.
Iibhodi zeesekethe eziprintiweyo ziye zaphuhliswa ukusuka kwi-single-layer ukuya kwi-double-side, i-multi-layer kunye neebhodi eziguquguqukayo, kwaye zihlala ziphuhliswa kwicala lokuchaneka okuphezulu, ukuxinana okuphezulu kunye nokuthembeka okuphezulu.Ngokuqhubekayo ukuncipha ubungakanani, ukunciphisa iindleko, kunye nokuphucula ukusebenza kuya kwenza ibhodi yesekethe eprintiweyo isagcina ubungqabavu obuqinileyo kuphuhliso lweemveliso ze-elektroniki kwixesha elizayo.
Kwixesha elizayo, indlela yokuphuhlisa itekhnoloji yokuvelisa ibhodi yesekethe kukuphuhlisa kwicala loxinaniso oluphezulu, ukuchaneka okuphezulu, ukuvuleka okuncinci, ucingo oluncinci, i-pitch encinci, ukuthembeka okuphezulu, i-multi-layer, ukuhanjiswa kwesantya esiphezulu, ubunzima obulula kunye imilo ebhityileyo.
