Chii PCB hwindo

Mawaya ari paPCB akafukidzwa nemafuta, ayo anogona kudzivirira pfupi dunhu uye kukuvadza kune chishandiso. Iyo inonzi iwindow ndeyekubvisa pendi mupendero pawaya, kuti waya iiswe pachena kune tini.

Maitiro ekugadzira pcb hwindo kuvhura pcb dhizaini yekumisikidza wiring hwindo kuvhura

Sezvauri kuona mumufananidzo uri pamusoro, iri nepahwindo. Kuvhura kwehwindo rePBB hakujairike, uye yakajairika ndiyo ingangoita memory module. Vaya venyu vakaparadzira komputa vanoziva kuti memory module ine chigunwe chimwe chegoridhe, sezvakaratidzwa mumufananidzo pazasi:

Chigunwe chegoridhe apa chinoreva kuvhura hwindo, plug uye kutamba.

Kuvhura hwindo zvakare kwakajairika basa, kureva kuti, ironing yemarata inowedzera hukobvu hwemapepa emhangura mune inotevera nhanho, iri nyore kune yazvino yazvino, inova yakajairika mubhodhi remagetsi uye bhodhi remota.

Vhura Windows uye mhangura yakajeka muPCB dhizaini

Mukugadzirwa, tinowanzo sangana nezvinodiwa nevatengi zvekuvhura Windows nekupenya mhangura, asi zvinonetsa kwazvo kutaurirana navo nekuti vatengi vane ruzivo rwushoma kana isu hatinyatso kujeka nezve maitiro aya. Mukugadzirwa kwedu, kazhinji vanosangana nevatengi vanofanirwa kuwedzera nhovo yekuvhara, ndiro kumucheto yemukati mhangura inopenya, kuburikidza negomba rakavhurika kuramba kutenderera, IC kupisa singi kumashure yakavhurika mhangura, yakabiwa gaba pad uye zvichingodaro. Zvinoenderana nemamiriro ezvinhu chaiwo, ngatitarisei mamwe emifananidzo kutsanangura.

1. Chivharo chekudzivirira

Kana mutengi achida kuwedzera chidziviriro, izvo zvatinofanira kuita kuwedzera soldmask nehupamhi hweinenge 1mm. Tinofanira kusimbisa nemutengi kana tichida kuwedzera mesh yesimbi. Kana tichiwedzera Soldmask, tinofanirwa kuisa ganda remhangura repasi network munzvimbo yekuwedzera Soldmask. Ndege yeSoldmask inofanirwa kuvharwa, zvikasadaro iyo substrate ichafumurwa (FR4, nezvimwewo). Mamwe asiri – epasi rese network haafanire kuyambuka iyo Soldmask. Wedzera iyo Soldmask nzvimbo kune iyo PCB mhedzisiro kuratidza yero mhangura. Nzvimbo dzisina kuvharwa dzichafukidzwa nekuvhara kwekuvhara.

2, Welding hwindo gomba

Mukugadzirwa, isu tinowanzonzwa iro rese bhodhi plug gomba kana yemuno plug plug, kana tichiwedzera maburi, isu tinoteerera kune iro plug gomba zita rekambani rinowanzo kuzirwa BGA, nekusiyana, hapana BGA ine welded hwindo gomba (yedu kambani kududzirwa). General kambani maratidziro anodarika 12mil maburi anofanirwa kuvezwa mawindo maburi.

3, IC kupisa kupisa pad

Kazhinji, kumusana kweIC kupisa kupisa padhi wedzera iwelding hwindo (wedzera kumashure soldmask yakakura kupfuura kana yakaenzana nepad pad gomba kuseri kweganda remhangura zviri nani kunze.

4. Kuba mapads

Mune wave soldering, kuti tigadzirise dambudziko rekubatanidza tini inokonzerwa nekuvharana kwepedhi kwemapedhi, isu tinoshandisa tadpole chimiro chebavha mapadhi. Cherekedza ganda remhangura riine saizi imwechete senge iyo solder inofanira kuwedzerwa.

Maitiro ekuziva iyo tini paPCB wiring hwindo

Iyo dunhu inoda kutyaira iyo 8-chiteshi relay, kana iyo yakawanda-chiteshi relay yakavharwa kana iyo yazvino ichiwedzera, kuitira kuona chaiyo mhedzisiro, mukukudza razvino tambo panguva imwe chete, inotarisirwa kubvisa iyo yekushambadzira kuramba rukoko rwemutsara wazvino – girini yemafuta yakasara, mushure mekunge bhodhi raitwa, unogona kuwedzera tini kumusoro, kuomesa mutsetse, kunogona kupfuura zvazvino.

Mhedzisiro yacho ndeiyi inotevera:

Maitiro ekushandisa ari seanotevera:

Ingo dhonza mutsetse uri muToPlayer (kana bottomLayer zvinoenderana nechero tambo yakamisikidzwa iri) dura, uye wozodhonza mutsetse unoenderana nawo muTopsolder (kana pasi solder) dura.

Pcb dhizaini yekumisikidza wiring hwindo

CB dhizaini inogona kumisikidza waya wiring mu TOP / BOTTOM SOLDER rukoko.

TOP / BOTTOM SOLDER girini mafuta dura: Shongedza iyo TOP / BOTTOM dura ne SOLDER girini mafuta kudzivirira tini kubva kupfeka iyo yemhangura foil uye chengetedza kuputira.

Green mafuta ewindo rekuvharira rinogona kuiswa pad, kuburikidza neburi uye isiri yemagetsi wiring yeiyi dura.

1. Nokutadza, iyo pad ichavhura hwindo muPCB dhizaini (OVERRIDE: 0.1016mm), ndiko kuti, iyo pad inofumura mhangura foil, inowedzera 0.1016mm, uye tini ichawedzerwa panguva yekushongedzwa kwemhepo. Hapana dhizaini dhizaini inokurudzirwa kuti ive nechokwadi chekushomeka;

2. Nokutadza, gomba richavhura hwindo muPCB dhizaini (OVERRIDE: 0.1016mm), ndiko kuti, gomba rinofumura mhangura foil, kuwedzera 0.1016mm, uye tini ichawedzerwa panguva yekushongedzwa kwemhepo. Kana dhizaini iri kudzivirira tini kuti isapinda mugomba uye mhangura kuti isabude, iwe unofanirwa kutarisa iyo PENTING sarudzo mune yekuwedzera hunhu hwegomba muSOLDER MASK kuvhara gomba.

3, pamusoro pezvo, iri dura rinogona zvakare kuve rakazvimiririra risiri remagetsi wiring, kutenderera kurwisa mafuta egirini anoenderana nekuvhura kwewindo. Kana iri pane yemhangura foil waya, inoshandiswa kusimudzira iko iko iko kugona kwetambo, uye kugadzirwa kwetini kunowedzerwa kana uchipisa. Kana iri pane isiri-yemhangura foil waya, inowanzo gadzirirwa logo uye yakasarudzika yemunhu skrini yekudhinda, uye hunhu hwekudhinda dhizaini inogona kusiiwa.
