PCB silk screenkudhinda inzira yakakosha mukugadzirwa kwePCB circuit board, iyo inosarudza kunaka kweiyo yakapedzwa PCB board.PCB redunhu bhodhi dhizaini yakaoma kwazvo.Pane zvakawanda zviduku zvishoma mukugadzirisa maitiro.Kana ikasabatwa nemazvo, inokanganisa kushanda kwebhodhi rose rePCB.Kuti tiwedzere kugona kwekugadzira uye kunaka kwechigadzirwa, ndedzipi nyaya dzatinofanira kutarisisa panguva yekugadzira?
Iwo hunhu magiraidhi anoumbwa pane pcb bhodhi nesiriki sikirini kana inkjet kudhinda.Chimiro chega chega chinomiririra chikamu chakasiyana uye chinoita basa rakakosha mukugadzirwa kwekupedzisira.
Rega ndisume vanhu vanozivikanwa.Kazhinji, C inomirira capacitor, R inomiririra resistor, L inomiririra inductor, Q inomiririra transistor, D inomiririra diode, Y inomiririra crystal oscillator, U inomiririra integrated circuit, B inomiririra buzzer, T inomiririra transformer, K. inomirira Relays nezvimwe.
Pabhodhi redunhu, tinowanzoona nhamba dzakadai seR101, C203, nezvimwewo. Kutaura zvazviri, tsamba yekutanga inomiririra chikamu chechikamu, nhamba yechipiri inozivisa nhamba yebasa redunhu, uye nhamba yechitatu neyechina inomiririra nhamba ye serial padunhu. board.Saka isu tinonzwisisa zvakanyanya kuti R101 ndiyo yekutanga resistor pane yekutanga inoshanda redunhu, uye C203 ndiyo yechitatu capacitor pane yechipiri inoshanda redunhu, kuitira kuti kuzivikanwa kwehunhu kuve nyore kunzwisisa.
Muchokwadi, mavara ari paPCB wedunhu bhodhi ndiwo atinowanzo kudaidza kuti sirika sikirini.Chinhu chekutanga kuona nevatengi pavanowana PCB bhodhi ndiyo sirika sikirini pairi.Kuburikidza neaya silika skrini mavara, ivo vanogona kunyatsonzwisisa izvo zvikamu zvinofanirwa kuiswa munzvimbo yega yega panguva yekuiswa.Zviri nyore kuunganidza chigamba uye kugadzirisa.Saka ndeapi matambudziko anofanirwa kutariswa mune yekugadzira dhizaini yekudhinda sirika skrini?
1) Chinhambwe pakati pesiriki chidzitiro uye padhi: iyo sirika skrini haigone kuiswa padhi.Kana iyo padhi yakafukidzwa nesiriki sikirini, inokanganisa kutengeswa kwezvikamu, saka 6-8mil spacing inofanira kuchengetwa.2) Screen printing width: The screen printing line width inowanzopfuura 0.1mm (4 mill), izvo zvinoreva hupamhi hweinki.Kana upamhi hwemutsara hwakanyanya kudiki, inki haizobudi pachiratidziri chekudhinda, uye mavara haagone kudhindwa.3) Hunhu hurefu hwekudhinda sirika skrini: Hurefu hwehunhu hunowanzopfuura 0.6mm (25mil).Kana kureba kwemavara kuri pasi pe25mil, mavara akadhindwa anenge asina kujeka uye nekudzima nyore.Kana mutsara wemavara wakanyanya kukora kana chinhambwe chiri padyo zvakanyanya, zvinokonzeresa kudzima.
4) Iyo nzira yekudhinda sirika skrini: kazhinji kutevedzera musimboti wekubva kuruboshwe kuenda kurudyi uye kubva pasi kuenda kumusoro.
5) Polarity tsananguro: Zvikamu zvinowanzo kuve ne polarity.Iyo skrini yekudhinda dhizaini inofanirwa kutarisisa kumaka iyo yakanaka uye yakaipa matanda uye inotungamira zvikamu.Kana matanda akanaka uye asina kunaka akashandurwa, zviri nyore kukonzera pfupi pfupi, zvichiita kuti bhodhi redunhu ripise uye haigoni kuvharwa.
6) Kuzivikanwa kwepini: Kuzivikanwa kwepini kunogona kusiyanisa kutungamira kwezvikamu.Kana mavara esiriki skrini akamaka chiziviso zvisizvo kana pasina chiziviso, zviri nyore kuita kuti zvikamu zvigadzirwe kumashure.
7) Silk sikirini chinzvimbo: Usaise sirika sikirini dhizaini pagomba rakaboorwa, zvikasadaro akadhindwa pcb bhodhi richava asina kukwana mavara.
Pane zvakawanda zvakatemwa uye zvinodikanwa zvePCB sirika skrini dhizaini, uye ndizvo zvakatemwa zvinosimudzira kuvandudzwa kwePCB skrini yekudhinda tekinoroji.
