Mabhodhi edunhu akadhindwa (PCBs) anoumba hwaro hwepasi hunotsigira uye nemagetsi hunobatanidza zvikamu zvemagetsi uchishandisa conductive copper traces uye mapedhi akasungirirwa kune isiri-conductive substrate. MaPCB akakosha kune angangoita ese emagetsi mudziyo, achigonesa kuzadzikiswa kweiyo yakanyanya kuomesesa dhizaini yedhizaini kuita akabatanidzwa uye akawanda anogadzirwa mafomati. Pasina PCB tekinoroji, indasitiri yemagetsi ingadai isipo sezvatinoiziva nhasi.
Iyo PCB yekugadzira maitiro inoshandura zvigadzirwa zvakaita semucheka wefiberglass uye foil yemhangura kuita mabhodhi einjiniya chaiwo. Inosanganisira anopfuura gumi neshanu matanho akaomarara ekushandisa sophisticated otomatiki uye yakasimba maitiro ekutonga. Kuyerera kwemaitiro kunotanga neiyo schematic kubatwa uye marongero edunhu rekubatanidza pane zvemagetsi dhizaini otomatiki (EDA) software. Artwork masks anobva atsanangura nzvimbo dzekuteedzera dzinosarudzika dzinoratidza mafoto emhangura laminate vachishandisa photolithographic imaging. Etching inobvisa mhangura isina kuvhurika kuti isiye kumashure ega ega conductive nzira uye yekubata pads.
Multi-layer boards sandwich pamwe yakaoma copper clad laminate uye prepreg bonding sheets, kusanganisa micherechedzo palamination pasi pekumanikidza kwakanyanya uye tembiricha. Michina yekuchera yakatakura zviuru zvemakomba madiki akabatana pakati pematanho, ayo anobva aputirwa nemhangura kuti apedze 3D yedunhu redunhu. Kuchera kwechipiri, kupepeta, uye kutenderera kunoenderera mberi nekugadzirisa mabhodhi kusvika agadzirira zvekushongedza silkscreen. Automated optical inspection uye bvunzo inosimbisa inopesana nemitemo yekugadzira uye zvakatemwa pamberi pekutumira kwevatengi.
Mainjiniya anotyaira anoenderera mberi PCB magadzirirwo anogonesa denser, nekukurumidza, uye zvakanyanya kuvimbika zvemagetsi. Yakakwira density interconnect (HDI) uye chero-layer tekinoroji ikozvino yabatanidza pamusoro pezvikamu makumi maviri kuenda kunzira yakaoma yedhijitari processors uye radio frequency (RF) masisitimu. Rigid-flex mabhodhi anosanganisa zvinhu zvakaoma uye zvinochinjika kusangana nezvinodiwa zvechimiro. Ceramic uye insulation simbi inotsigira (IMB) substrates inotsigira yakanyanyisa yakakwirira frequency kusvika millimeter-wave RF. Iyo indasitiri zvakare inotora zvakatipoteredza hushamwari maitiro uye zvinhu zvekuchengetedza.
Iyo yepasi rose PCB indasitiri yekuchinja inodarika mabhiriyoni makumi manomwe neshanu emadhora kune vanopfuura zviuru zviviri zvevagadziri, vakakura pa 3.5% CAGR munhoroondo. Kupatsanurwa kwemusika kunoramba kwakakwira kunyangwe kubatanidzwa kunoenderera zvishoma nezvishoma. China inomiririra hwaro hombe hwekugadzira ine inopfuura 55% share uku Japan, Korea neTaiwan vachitevera pamusoro pe25% pamwechete. North America inotora isingasviki 5% yepasi rose. Iyo indasitiri mamiriro anochinja akananga kuAsia mukana muhukuru, mutengo, uye padyo nemaketani makuru ekupa zvemagetsi. Nekudaro, nyika dzinochengetedza kugona kwePCB yemuno kutsigira kudzivirira uye kunzwisiswa kwepfuma.
Sezvo hunyanzvi hwemagetsi evatengi huchikura, maapplication ari kubuda mumafambisirwo ekutaurirana, kufambiswa kwemagetsi, otomatiki, aerospace, uye masisitimu ekurapa anokurudzira kukura kweindasitiri yePCB. Kuenderera mberi kwekuvandudza tekinoroji kunobatsirawo kuwanda kwemagetsi zvakanyanya kupararira mumakesi ekushandiswa kwemaindasitiri nekutengesa. MaPCB acharamba achishandira nharaunda yedu yedhijitari uye yakangwara mumakumi emakore ari kuuya.
