Matanho eceramic redunhu bhodhi kugadzira maitiro

Asi wakambozvibvunza here kuti aya maceramic circuit board anogadzirwa sei? Ndeapi matanho anobatanidzwa mukugadzira kwavo? Mune ino blog positi, isu tinotora yakadzika kupinda munyika yakaoma yeceramic redunhu bhodhi kugadzira, tichiongorora nhanho yega yega inobatanidzwa mukugadzirwa kwayo.

Nyika yemagetsi inogara ichishanduka, uye ndizvo zvakaitawo zvinhu zvinoshandiswa kugadzira zvigadzirwa zvemagetsi. Ceramic circuit boards, inozivikanwawo seceramic PCBs, yakawana mukurumbira mumakore achangopfuura nekuda kwekunaka kwemafuta ekupisa uye magetsi ekudzivirira. Aya mabhodhi anopa akawanda mabhenefiti pamusoro pechinyakare akadhindwa edunhu mabhodhi (PCBs), achiaita akanakira akasiyana ekushandisa uko kupisa kwekupisa uye kuvimbika kwakakosha.

Danho 1: Dhizaini uye Prototype

Danho rekutanga muceramic redunhu rekugadzira bhodhi rinotanga nekugadzira uye prototyping yedunhu redunhu. Izvi zvinosanganisira kushandisa yakasarudzika software kugadzira schematic uye kuona marongero uye kuiswa kwezvikamu. Kana iyo yekutanga dhizaini yapera, prototypes anogadzirwa kuti aedze mashandiro ebhodhi uye mashandiro asati apinda muchikamu chekugadzira vhoriyamu.

Danho Rechipiri: Kugadzirira zvinhu

Kana iyo prototype yatenderwa, zvinhu zveceramic zvinoda kugadzirirwa. Ceramic circuit boards inowanzogadzirwa nealuminium oxide (aluminium oxide) kana aluminium nitride (AlN). Zvinhu zvakasarudzwa zvinogadzirwa pasi uye zvinosanganiswa nekuwedzera kuti zviwedzere hupfumi hwavo, senge thermal conductivity uye simba remagetsi. Musanganiswa uyu unobva watsindirwa mumashizha kana matepi akasvibira, akagadzirira kuenderera mberi.

Nhanho 3: Kugadzira Substrate

Munguva iyi, tepi yakasvibirira kana pepa inopinda maitiro anonzi substrate formation. Izvi zvinosanganisira kuomesa zvinhu zveceramic kubvisa unyoro uye wozocheka muchimiro chaunoda uye saizi. CNC (kombuta nhamba yekudzora) michina kana laser cutters inowanzo shandiswa kuwana chaiwo zviyero.

Danho rechina: Circuit Patterning

Mushure meiyo ceramic substrate yakaumbwa, nhanho inotevera ndeyekutenderera patterning. Apa ndipo panoiswa runyoro rwakatetepa rwezvinhu zvinoitisa, semhangura, pachishandiswa nzira dzakasiyana siyana. Nzira yakajairika ndeyekudhindisa skrini, uko template ine inodiwa redunhu pateni inoiswa pane substrate uye conductive inki inomanikidzwa kuburikidza netemplate pamusoro.

Danho 5: Kutamba

Mushure mekunge dhizaini yaumbwa, iyo ceramic circuit board inosangana neyakakomba nzira inonzi sintering. Kupisa kunosanganisira kudziyisa mahwendefa kusvika kune tembiricha yepamusoro mumhepo inodzorwa, kazhinji muchoto. Iyi nzira inosanganisa ceramic zvinhu uye conductive traces pamwechete kugadzira yakasimba uye yakasimba redunhu bhodhi.

Nhanho 6: Metallization uye Plating

Kamwe bhodhi rave sintered, nhanho inotevera ndeye metallization. Izvi zvinosanganisira kuisa chidimbu chesimbi, senge nickel kana goridhe, pamusoro pematakwa emhangura ari pachena. Metallization inoshandisa zvinangwa zviviri - inodzivirira mhangura kubva kune oxidation uye inopa zviri nani solderable pamusoro.

Mushure memetallization, bhodhi rinogona kuita mamwe maitiro ekuputira. Electroplating inogona kukwidziridza zvimwe zvivakwa kana mabasa, senge kupa inotengeswa pamusoro pekupedzisira kana kuwedzera jira rekudzivirira.

Danho rechinomwe: Ongorora uye Edzai

Kudzora kwehunhu chinhu chakakosha chechero nzira yekugadzira, uye ceramic redunhu bhodhi kugadzira hakuna musiyano. Mushure mokunge bhodhi redunhu ragadzirwa, rinofanira kuongororwa zvakasimba uye kuongororwa. Izvi zvinoita kuti bhodhi rega rega rinosangana nezvinodiwa uye zviyero, zvinosanganisira kutarisa kuenderera mberi, kuramba kwekudzivirira uye chero hurema hunogona kuitika.

Danho 8: Gungano uye Packaging

Kana bhodhi rapfuura nhanho dzekuongorora uye dzekuyedza, yagadzirira kuungana. Shandisa otomatiki midziyo kune solder zvinhu zvakadai resistors, capacitors, uye akabatanidzwa maseketi pamabhodhi edunhu. Mushure megungano, mabhodhi edunhu anowanzo kurongedzerwa mumabhegi e-anti-static kana mapallets, akagadzirira kutumirwa kunzvimbo yavanoda kuenda.

Muchidimbu

Iyo ceramic yedunhu bhodhi yekugadzira maitiro inosanganisira akati wandei akakosha matanho, kubva pakugadzira uye prototyping kusvika kune substrate kuumbwa, dunhu pateni, sintering, metallization, uye kuyedza. Nhanho yega yega inoda humbowo, hunyanzvi uye kutarisisa kune zvakadzama kuona kuti chigadzirwa chekupedzisira chinosangana nezvinodiwa. Izvo zvakasiyana-siyana zveceramic circuit boards zvinovaita sarudzo yekutanga mumaindasitiri akasiyana-siyana, kusanganisira aerospace, motokari uye telecommunications, uko kuvimbika uye kutonga kwekushisa kwakakosha.
