Ndezvipi zvainyanya kuitwa kaviri rukoko pcb bhodhi uye multi-rukoko redunhu bhodhi uye sei kusiyanisa kwavari Ngatitorei vanotevera? Pcb bhodhi bhizimisikuti inzwisise:

Double rukoko pcb bhodhi

Mabhodhi ane mativi maviri ane wiring pamativi ese, asi kuti ushandise mativi ese ewaya, panofanirwa kuve nemubatanidzwa wemagetsi pakati pemativi maviri. Iri "zambuko" pakati pemasekete inonzi gomba rinotungamira (VIA). gomba diki muPCB, rakazadzwa kana rakaputirwa nesimbi, iro rinogona kusunganidzwa netambo pamativi ese maviri Nekuti mapaneru akapetwa ane nzvimbo yakapetwa kaviri, uye nekuti iyo wiring inogona kuvharika (iyo inogona kukuvadzwa yakatenderedza rimwe divi), zvirinani zvirinani kune mamwe maseketi akaomarara pane ipaneru rimwe chete.

Nounyanzvi kaviri mapaneru rudzi rwePCB redunhu bhodhi rakakosha kwazvo mukati, iye chinangwa chevakuru, kuona kana bhodhi pcb bhodhi mbiri mapaneru iri nyore, kunzwisisa kweimwe chete pani ndeyekutenda zvachose shamwari dzinogona kubata, kuwedzera yeiyo chete pani, yakapetwa kaviri inoreva imwechete pani tambo yakakwana kuti iende kune yakapesana, yakapetwa mbiri, uye paive chakakosha chimiro iguru gomba.Pfungwa yakapusa ndeyekuti yakapetwa-mativi mutsara, mativi ese ari maviri emutsara! bracket is: double sided line board is double panel! Dzimwe shamwari dzinozobvunza senge bhodhi ine mativi maviri waya, asi divi rimwe chete rine zvikamu zvemagetsi, rakadai bhodhi mushure mezvose ipaneru mbiri kana pani imwechete? Mhinduro iri pachena , rakadaro bhodhi ipaneru mbiri, mune iwo maviri mapaneru bhodhi akaiswa pazvikamu.

Multilayer wedunhu mabhodhi ari nyore kusiyanisa

Dunhu redunhu zvinoenderana nesarudzo yakawanda sei yeiyo wiring process kuomarara uye machining mutengo, zvakajairika dunhu bhodhi ine imwechete tambo uye yakapetwa mutsara, inowanzozivikanwa seyepaneru rimwe uye maviri mapaneru, epamusoro-magumo zvigadzirwa zvemagetsi, zvisinei, nekuda kwechigadzirwa nzvimbo dhizaini zvinhu , pamusoro peiyo yepamusoro wiring, yemukati stack multilayer wedunhu, maitiro ekugadzira, akaita yega yega yega mushure mutsara, zvakare kuburikidza neiyo optical kifaa kumisikidza, kudzvanya, rega iyo superposition yeakawandisa-masenduru wedunhu mune chidimbu chedunhu bhodhi. se multilayer redunhu bhodhi.Yese wedunhu bhodhi yakakura kudarika kana yakaenzana nemaviri materu inogona kunzi akawanda-masenduru wedunhu bhodhi.Multi-layer wedunhu bhodhi inogona kukamurwa kuita akawanda-maseru akaomesesa wedunhu bhodhi, akawanda-masenduru akapfava uye akaoma wedunhu bhodhi, akawanda -mutambi nyoro uye wakaoma wakabatanidzwa wedunhu bhodhi.

Kuberekwa kwemazhinji multilayer wedunhu bhodhi

Kuwedzera kwehuwandu hwe IC mapakeji kunotungamira kune yakanyanya kuwanda kwekubatana, izvo zvinoda kushandiswa kweakawanda substrates.Zvisingaonekwe dhizaini dhizaina senge ruzha, kurasika capacitance, crosstalk inoonekwa muchimiro chemaseketi akadhindwa.Saka, pcb dhizaini inofanira kuve yakanangana nekudzikisa kureba kwemutsara wemutsetse uye kudzivisa nzira dzinoenderana Nezviri pachena, mune rimwe chete pani, kana kunyangwe mune mbiri mapaneru, izvi zvinodiwa hazvigone kupindurwa zvinogutsa nekuda kwenhamba shoma yekuyambuka iyo inogona kuitiswa .Panyaya yekuwanda kwenhamba yekubatana. uye zvinoda kuyambuka, iro bhodhi dura rinofanira kuwedzerwa kusvika pamatanho anodarika maviri kuti uwane kuita kunogutsa. Naizvozvo, chinangwa chekutanga chemabhodhi-masenduru emabhodhi kupa rusununguko rwakawanda kumatunhu akaomarara uye / kana ane ruzha anonzwikwa kusarudza akakodzera. wiring nzira wedunhu: multilayer redunhu bhodhi ine angangoita matatu anodzvara akaturikidzana, maviri acho ane yekunze nzvimbo, uye yakasara dura iri Kubatana kwemagetsi pakati pavo kunowanzoitwa nekupaza kuburikidza nemakomba muchikamu chemuchinjikwa webhodhi redunhu.Multilayer akadhindwa wedunhu mabhodhi, semapaneru maviri, anowanzo kufusirwa kuburikidza ne - bhandi mahwendefa kunze kwekunge zvaratidzwa neimwe nzira.

Multilaminates inogadzirwa nekukochekera maviri kana anopfuura macircuit ari pamusoro peumwe neumwe, aine yakavimbika pre-set kubatana pakati pavo.Sezvo kuchera uye electroplating kunoitwa zvisati zvaiswa matanda ese, nzira iyi inotyora echinyakare yekugadzira maitiro kubva pakutanga Iwo maviri emukati matanda akaumbwa neyakajairika mapaneru maviri, nepo ekunze akaturikidzana akaumbwa akapatsanurwa kamwechete mapaneru.Pamberi pekuumburudzwa, emukati mahwendefa anocherwa, akasungirirwa nemagetsi kuburikidza nemakomba, akaendeswa graphic, akagadzirwa uye akaiswa. rukoko rwegomba ndiwo mucherechedzo wedare, uyo wakafukidzwa nenzira yekuti ugadzire mhete yemhangura yakaenzana mukati memucheto wemukati wegomba. Iwo matanda anozoumburudzwa pamwechete kuti aumbe muzvikamu zvakawanda, izvo zvinogona kusunganidzwa ne wave soldering.

Iko kuumbana kunogona kuitwa mune yemuchina wekudzvinyirira kana mukamuri inodzvinyirira (autoclave) Mune hydraulic muchina, izvo zvakagadzirirwa (zvekumanikidza zvimisikidzwa) zvinoiswa pasi pechando kana preheated kumanikidza (iwo maratidziro eiyo yakakwira girazi tembiricha tembiricha inoiswa pa 170-180 ° C) Iyo tembiricha yekuchinja tembiricha ndiyo tembiricha iyo iyo amorphous dunhu repolymer (resin) kana chikamu chekristalline polymer chinoshanduka kubva kune yakaoma, panzvimbo pacho brittle nyika kune viscous, yeraby nyika.

Multilaminates inoiswa mukushandisa mune yakasarudzika zvigadzirwa zvemagetsi (makomputa, zvishandiso zvemauto), kunyanya mumamiriro ehuremu uye kuwandisa kuwanda .Zvisinei, izvi zvinogona kuitika chete nekuwedzera mutengo wemaminiti mukutsinhana nenzvimbo yakawanda uye hushoma huremu. kumhanya maseketi, laminates zvakare anobatsira zvakanyanya sezvo iwo achipa iwo madhizaina akadhindwa wedunhu mabhodhi ane anopfuura maviri maviri materu emabhodhi ewiring uye anopa makuru nzvimbo dzevhu uye simba.

Iyi iripamusoro nzira yekusiyanisa iwo maviri-mativi wedunhu bhodhi uye akawanda-masenduru wedunhu bhodhi, ini ndinovimba iwe uchafarira; Isu tiri wedunhu bhodhi vagadziri , tinogamuchirwa kubvunza nezve ~
