I-IPC imemezele okutholwe ngoNovemba 2020 kuhlelo lwayo Lwezibalo Lwe-North American Printed Circuit Board (PCB).Isilinganiso sencwadi nenkokhelo simi ku-1.05.
Ingqikithi yokuthunyelwa kwe-PCB yaseNyakatho Melika ngoNovemba 2020 ikhuphuke ngamaphesenti angu-1.0 uma kuqhathaniswa nenyanga efanayo ngonyaka odlule.Uma kuqhathaniswa nenyanga edlule, ukuthunyelwa ngoNovemba kwehle ngamaphesenti angu-2.5.
Ukubhukha kwe-PCB ngoNovemba kukhuphuke ngamaphesenti angu-17.1 unyaka nonyaka futhi kwenyuke ngamaphesenti angu-13.6 kusukela ngenyanga edlule.
"Ukuthunyelwa nama-oda we-PCB kuyaqhubeka nokuguquguquka ngandlela thile kodwa kuhambisana nezimo zakamuva," kusho uShawn DuBravac, isazi sezomnotho esikhulu se-IPC.“Nakuba ukuthunyelwa kwehle kancane ngaphansi kwesilinganiso sakamuva, ama-oda akhuphuke ngaphezu kwesilinganiso sawo futhi ephakeme ngamaphesenti angu-17 kunonyaka odlule.”
Idatha enemininingwane Iyatholakala
Izinkampani ezibamba iqhaza oHlelweni Lwezibalo Lwezibalo lwe-IPC lwe-IPC yaseNyakatho Melika zikwazi ukufinyelela ekutholeni okuningiliziwe nge-PCB eqinile kanye nokuthengiswa kwesekethe okuguquguqukayo nama-oda, okuhlanganisa izilinganiso ezihlukene eziqinile neziguquguqukayo zencwadi-kuya-inkokhiso, amathrendi okukhula ngezinhlobo zomkhiqizo nezigaba zikasayizi wenkampani, isidingo sama-prototypes. , ukukhula kokuthengisa ezimakethe zempi nezokwelapha, nenye idatha efike ngesikhathi.
Ukutolika Idatha
Izilinganiso zencwadi nebhili zibalwa ngokuhlukanisa inani lama-oda abhukhwe ezinyangeni ezintathu ezedlule ngevelu yokuthengisa ekhokhiswe ngesikhathi esifanayo ezinkampanini ezikusampula yenhlolovo ye-IPC.Isilinganiso esingaphezu kwe-1.00 siphakamisa ukuthi isidingo samanje singaphambi kokunikezwa, okuyinkomba enhle yokukhula kokuthengisa phakathi nezinyanga ezintathu kuya kweziyishumi nambili ezizayo.Isilinganiso esingaphansi kuka-1.00 sibonisa ukuhlehla.
Izinga lokukhula konyaka nonyaka kanye nonyaka kuze kube manje linikeza umbono ophusile wokukhula kwemboni.Ukuqhathanisa kwenyanga nenyanga kufanele kwenziwe ngokuqapha njengoba kubonisa imiphumela yesizini kanye nokuntengantenga kwesikhashana.Ngenxa yokuthi ukubhukha kuvame ukuba nezimo ezishintshashintshayo kunokuthunyelwa, izinguquko ezilinganisweni zencwadi nenkokhiso kusukela ngenyanga kuya enyangeni zingase zingabaluleki ngaphandle kwalapho kubonakala ukuthambekela okungaphezu kwezinyanga ezintathu ezilandelanayo.Kubalulekile futhi ukucabangela izinguquko kukho kokubili ukubhukha nokuthunyelwa ukuze uqonde ukuthi yini eqhuba izinguquko esilinganisweni sencwadi nenkokhiso.
