PCB yekugadzira pfungwa: PCB kugadzira kunotanga nePCB “substrate” yakagadzirwa neGirazi Epoxy kana zvimwe zvakafanana. Nhanho yekutanga yekugadzira ndeyekugadzira wiring ye-on-line PCB pakati pezvikamu nekushandisa nzira yeSubtractive transfer ku “print” mutsara usina kunaka wePCB board yakagadzirwa pane simbi conductor.

Icho hunyengeri ndechekuparadzira nhete nhete yemhangura foil pamusoro penzvimbo yese uye kubvisa chero yakawandisa. Kana iwe uri kugadzira kaviri-paneli PCB, foil yemhangura inovhara mativi ese e substrate. Uye kuda kuita multilayer board kuti ugone kuita mbiri mbiri kumeso ndiro ine tailormade adhesive “press close” inosimuka yakaenda.

Tevere, kudhirowa uye plating inodiwa kuti ubatanidze muzvikamu zvinogona kuitwa paPCB board. Mushure mekucherwa nemuchina sezvinodiwa, maburi anofanira kunge akaiswa mukati (Plated through-hole Technology, PTH). Mushure mekugadzira simbi yekurapa mukati megomba, mitsara yemukati yega yega yega inogona kubatanidzwa kune mumwe nemumwe.

Makomba anofanirwa kucheneswa marara asati atanga kugadzira. Izvi zvinodaro nekuti resin epoxy inoburitsa mamwe makemikari shanduko mushure mekupisa, uye inovhara yemukati PCB layer, saka inofanira kutanga yabviswa. Kuchenesa nekuputira kunoitwa mumakemikari. Tevere, solder pendi (solder inki) inoiswa kune yekunze pcb dhizaini wiring kuitira kuti pcb dhizaini wiring isabate iyo yakanamirwa chikamu.

Iwo akasiyana echinyorwa zvinyorwa zvinobva zvadhindwa pabhodhi redunhu kuratidza nzvimbo yechikamu chimwe nechimwe. Iyo haifanirwe kufukidzwa pane chero PCB dhizaini wiring kana chigunwe chegoridhe, zvikasadaro inogona kuderedza solderability kana kugadzikana kwekubatana kwazvino. Pamusoro pezvo, kana paine simbi yakabatana, chikamu che “munwe” chinowanzo kuputirwa negoridhe kuti ive nechokwadi chemhando yepamusoro yekubatanidza ikozvino kana yaiswa mune yekuwedzera slot. Pakupedzisira, pane muedzo. Kuedza PCB yedunhu pfupi kana kuvhurika dunhu, optical kana yemagetsi bvunzo inogona kushandiswa. Mayedzo eOptical anoshandisa ma scan kuti awane kukanganisa muzvikamu, ukuwo bvunzo dzemagetsi dzinowanzo shandisa flyprobe kutarisa zvese zvinongedzo. Kuyedzwa kwemagetsi kwakaringana pakutsvaga mapfupi maseketi kana mabhureki, asi bvunzo dzemaziso dzinogona kuona zviri nyore matambudziko nemagapu asiri iwo pakati pemakondakita.

Pcb substrate mushe, mushure mekupedzisa chidimbu chebhodhi rakakura riri paPCB substrate michina zvinoenderana nezvinodiwa zvakasiyana zvidiki uye zvidiki zvikamu – shandisa SMT otomatiki yekuisa muchina wekutanga IC chip uye SMD zvikamu “Welding, bhuku plug mamwe michina anoita basa, kuburikidza neiyo wave/reflow soldering process iyo splice zvikamu zvakasimbiswa paPCB, A motherboard rakagadzirwa. Kurapa nzira: Floor kirasi:

1, kuchengetedzwa kwepasi: chengetedza huni pasi, inofanirwa kuchengetedza firimu rependi yepasi payo pamusoro pezvose, haigone kukuvadza “kutaridzika” kwayo, zvisinei, semhedzisiro yefirimu yefurati yehuni pamusoro peumwe neumwe, chengetedza nzira saizvozvo futi hazvina kufanana.

Nitro huni varnish pasi: isina kunaka pukuta nemucheka wakanyorova kana mvura, kuti urege kurasikirwa nekupenya uye goko. Nhema dzese pakati pehafu yegore kana mwedzi mishoma, bhurasha newaini yakasimwa, tora zvakare yakachena donje gauze rinotevera pukuta rinogona. Shandisa tauro nyoro kana shinda yedonje panguva dzakajairika pukuta guruva rependi firimu rinogona. Chenjerera kudzivirira kuratidzwa uye kuputa.

Broad lacquer uye lacquer pasi: haigoni kazhinji kupukuta nemvura yakachena yeyakadzika tembiricha bhurashi.

Wana pamwe ammonia mafuta lacquer mhando yepasi bhodhi: isina kunaka pukuta nemvura, kuti arege kupukuta pamusoro mafuta ari ehunhu, uye kudzikisira kubwinya kwepamusoro. Doro acerbity varnish pasi: jira nyoro kana tauro rakapfava rinogona kushandiswa kana uchishandisa pukuta pukuta, zvisina kunaka kupasa chinhu chinopisa pane ino mhando yepasi, haigone kufukidza pamusoro nepepa repurasitiki kana chinhu chemhando yepepa. Kechipiri, kuchengetedzwa kwepasi pehuni kunofanirwa zvakare kutarisisa kudzivirira inorema simbi yakapinza maturusi, mataira egirazi, chipikiri uye zvimwe zvinhu zvakaoma kukwenya pasi, usatenderedza fenicha muvhu repasi dhonza kufamba; Dzivisa kutsika zvigubhu zvefodya pasi uye nekuisa asidhi uye alkali zvinhu; Usaisa zvakananga kettle, chitofu uye zvimwe zvinhu zvakakwirira zvekushisa.

Pasi pehuni kuri mushure mekushandisa kwenguva yakareba, kuoneka chakare chiitiko, kunofanirwa kukwira munguva lacquer. Lacquer nzira ine mhando mbiri: imwe mhando ndeyokukwira yakananga lacquer uye kuchorea, maitiro ayo uye kuveza fenicha zvakafanana, pasi wakisi pane besmear mushure mekumirira pakaoma, 2 ndeyekuti haudi chero ruvara rwekugadzira base base, zvakare inoda kwete chero pendi, bhurasha newafa yepasi zvakananga zvakadaro. Nekuti huni pevhu rudzi rwezvinhu zvakasikwa, pfeka mushe kwete chete, uye uchiri kukwanisa kudzosa senguva nezuva rimwe nerimwe rinopfuura rakakwana, zvakanyanya zvakasikwa, kunyanya yakachena bhurasho wakisi huni pasi, inozove yakajeka zvikuru, inotsvedzerera, yakanaka.

2, kuchengetedza pasi laminate

Iko kushandiswa kweaggrandizement huni pasi kunochengetedza nyore, kuda kuona zvinotevera pfungwa chete mukushandiswa kwezuva nezuva, kunogona kuvimbisa kushandiswa kwakajairwa kwepasi.

(1) Mapuriro ese emapuranga anochinja hunyoro hwawo nekuwedzera uye kudzikira kwehunyoro kana shanduko tembiricha, zvichikanganisa kuwedzera kwevhu. Chikonzero chinofanira kufanana nedziviriro yeganda zvakafanana, chengetedza hunyoro hunyoro zvemukati mevhu.

(2) Uriri kazhinji haudi kukora nekupenda. Usashandise sandpaper kupora.

(3) Inokurudzirwa kuisa rubhu MATS pamusuwo kudzivirira guruva kupinda nekukuvadza pasi.

(4) Iwo mavara nemafuta emafuta ari pasi pevhu anofanirwa kucheneswa nevanochenesa dzimba. Usashandise mvura yakawanda kuchenesa pasi.

(5) nzvimbo dzekuchamhembe dzakaoma, munguva yechando dzinofanira kutarisisa kuwedzera hunyoro hwepasi pevhu, ine nyoro mop mop, zvakakodzera kuwedzera hunyoro hwepamusoro, inogona kunyatsogadzirisa gaka repasi uye kuputika. Kana mitswe ikaitika munzvimbo dzakasiyana, ndapota zivisa iyo yekutengesa unit munguva uye zadza zvikamu. Mushure mekuzadza, wedzera hunyoro hwepamusoro kuti ufambise kupora pasi.

Munguva yekunaya, ndapota vhara maWindows zvakaringana kuti irege kunaya.

7 Kana ukawana pasi pobvu mvura, inofanira kubvarura pasi iyo yakanyoroveswa nemvura nekukurumidza sezvazvinogona, mumumvuri nzvimbo mweya wakaoma kana yakakodzera ziviso yekutengesa unit inoita kugadzirisa.

(8) Pamusuo wechimbuzi nekicheni, ngwariro inofanira kubhadharwa pakucheneswa kwemvura panguva.

(9) Usakweva paunenge uchibata fenicha. Zvinokurudzirwa kuisimudza.
