Ungayithola Kanjani I-PCB Silkscreen Egculisayo?

Isikrini sesilika siwungqimba oluphrintiwe lombhalo nezimpawu ku-PCB - izinkomba zokubhekisela, izimpawu ze-polarity, ama-logo, kanye nezixwayiso - eziguqula ibhodi elingenalutho libe yinto umuntu ohlanganisayo, umhloli, kanye nochwepheshe abangayifunda ngempela. Isikrini sesilika esihle sishesha ukuhlanganisa futhi sivimbele amaphutha; isikrini sesilika esingenamsebenzi sihlanganisa amaphedi, singafundeki, noma siqedwe ekukhiqizweni. Lo mhlahlandlela uchaza ukuthi iyini isikrini sesilika, imithetho yokuklama esigcina sifundeka, imibala kanye nezinketho zohlelo lokusebenza, kanye nendlela i-Highleap Electronics ekhiqiza ngayo izinganekwane ezihlanzekile nezifundekayo.

1. Iyini i-PCB silkscreen futhi kwenzekani kuyo?

Isikrini se-PCB silkscreen ungqimba oluphrintiwe lukayinki — ngokuvamile olumhlophe — olufakwa phezu kwemaski yokwenezela ukuze kufakwe umbhalo nezimpawu ezifundwa ngabantu ebhodini: abaklami bezinkomba zezingxenye, amamaki e-pin-one kanye ne-polarity, igama lebhodi kanye nokubuyekezwa, ama-logo, amaphuzu okuhlola, kanye nezimpawu zokuxwayisa noma zokuphepha. Ayinawo umsebenzi kagesi; umsebenzi wayo ulwazi, okwenza ibhodi likwazi ukuhlanganisa, ukuhlola, kanye nokulungisa ngendlela efanele.

Lolo lwazi lubalulekile kuzo zonke izigaba: abaklami bezinkomba batshela i-assembler kanye ne-pick-and-place ukuthi iyiphi ingxenye eya lapho, izimpawu ze-polarity zivimbela ukufakwa emuva, futhi umbhalo wokubuyekeza ukhomba ibhodi. Isikrini se-silkscreen sisetshenziswa phezu kwemaski ye-solder , ngakho-ke izendlalelo ezimbili zisebenza ndawonye ngokubonakalayo, futhi isikrini se-silkscreen esenziwe kahle kwi-PCB singenye yezinto ezilula kakhulu ezihlukanisa ibhodi lochwepheshe nelididayo.

2. Imithetho yokuklama isikrini se-silkscreen se-PCB: umbhalo omncane kanye nobubanzi bomugqa

Imithetho eyinhloko yokuklama isikrini sesilika iwububanzi bomugqa obuncane kanye nokuphakama kombhalo umenzi angakuphrinta ngokuthembekile, futhi akalokothi abeke isikrini sesilika phezu kwamaphedi noma ama-via avele obala. Umbhalo ongaphansi kobuncane uba yi-blob engacacile, engafundeki, kanti uyinki ephepheni uphazamisa ukugoqa - ngakho ukufundeka kanye nokususwa yizithiyo ezimbili ezibalulekile. Imithetho Eyinhloko:

• Ububanzi bomugqa obuncane. Umugqa ngamunye kufanele ube banzi ngokwanele ukuze inqubo yokuphrinta ibonakale ihlanzekile; imigqa emincane iyagcoba noma iqhekeke.
• Ukuphakama kombhalo okuncane. Izinhlamvu zidinga ukuphakama okuncane (kanye nesilinganiso sobubanzi nokuphakama) ukuze zihlale zifundeka; umbhalo omncane uyinki elahlekile.
• Akukho silkscreen kuma-pad. Gcina uyinki ungenazo izingcezu ezisongelwayo kanye nensimbi eveziwe, ngoba iphazamisa ukusongelwa futhi ingabangela amaphutha.
• Kusuliwe ama-vias nezimbobo. Uyinki owela embobeni noma embobeni awubonakali kahle futhi awusebenzi kahle.

Izinga eliphansi eliqondile lincike endleleni yokusebenzisa kanye nekhono lomenzi, ngakho-ke ziqinisekise kunokuba uzicabangele. Le mithetho iyingxenye yokuklama ibhodi elakha ngokuhlanzekile, umndeni ofanayo wokuhlola ohlanganiswe kunoma yikuphi ukubuyekezwa kwezinkinga zokukhiqiza - isikrini se-silkscreen esiphula sona sivame ukunqunywa buthule noma sishiywe yizinto ezinhle.

3. Indlela yokuhlela isikrini se-silkscreen ukuze kuhlanganiswe kahle futhi kungenamaphutha

Hlela isikrini se-silkscreen ukuze wonke umuntu ochaza izinkomba ahlotshaniswe ngokucacile nengxenye yaso, eqondiswe njalo ukuze kube lula ukuyifunda, futhi engalokothi ifihlwe ngaphansi kwengxenye eyiphawulayo — umgomo ukuthi umuntu ohlanganisayo akwazi ukubona nokuqondisa yonke ingxenye ngokushesha. Ukuhlelwa okucatshangelwe kahle yikona okuguqula isikrini se-silkscreen ekubeni yinto exakile sibe usizo lokuhlanganisa lwangempela:

• Beka abaklami eduze kwezingxenye zabo futhi ngokungaguquguquki (isb. konke kuyafundeka kusukela endaweni eyodwa noma ezimbili ezifanayo) ngakho-ke akukho ukungaqondakali mayelana nokuthi yiliphi ilebula elingaphansi kwaliphi ingxenye.
• Gcina amalebula ebonakala ngemva kokuhlanganiswa lapho kusebenziseka khona, ukuze kusize ekuhlolweni nasekusebenzeni kabusha, hhayi nje ukubekwa kokuqala - isibonisi esifihliwe ngaphansi kwengxenye yaso asinakufundwa kamuva.
• Maka i-polarity bese uphina eyodwa ngokucacile kuyo yonke ingxenye ehlukanisiwe, okuyisivikelo esikhulu kunazo zonke ekuhlanganisweni okungemuva.
• Gwema ukuminyana. Emabhodini aminyene, beka phambili izimpawu ezivimbela amaphutha kanye nokuhlanza okuphelele ukwakheka kwesikrini sesilika phezu kombhalo wokuhlobisa.

Inzuzo iwukuhlanganiswa okusheshayo, ukuhlolwa okulula, kanye namaphutha ambalwa okwakha. Emabhodini agcwele abantu kukhona ikhono langempela lokufaka amamaki acacile nawusizo ngaphandle kwamaphedi ahambisanayo noma omunye umbhalo, yingakho ukuhlela umthombo wesikrini sesilika kuwumsebenzi wokuklama ngokwawo.

4. Imibala yesikrini se-silkscreen se-PCB kanye nenhlanganisela ye-solder-mask

Umbala ojwayelekile wesikrini sesilika umhlophe, kodwa imibala emnyama, ephuzi, neminye iyatholakala, futhi ukukhetha kufanele kunikeze umehluko omkhulu uma kuqhathaniswa nombala we-solder-mask ukuze umbhalo uhlale ufundeka. I-silkscreen ne-solder mask ziyimbhangqwana ebonakalayo, ngakho-ke zikhethwa ndawonye ukuze zifundeke futhi zibukeke:

Umthetho osebenzayo uwukuthi umehluko: okumhlophe kokuluhlaza okotshani noma okumnyama kuyinhlanganisela yakudala, efundeka kalula, kuyilapho okufanayo okufanayo (njengesikrini esimnyama se-silkscreen esisesikhwameni esimnyama) kufanele kugwenywe ngoba umbhalo uyanyamalala. Uhla oluphelele lwemibala ye -solder-mask luhambisana nalezi zinketho zesikrini se-silkscreen, ngakho khetha inhlanganisela ukuze ifundeke kuqala bese kuthi okwesibili kube ubuhle — ikakhulukazi emabhodini lapho abahlanganisi kanye nochwepheshe kumele bafunde khona le ndaba ngokushesha.

5. Indlela i-silkscreen esetshenziswa ngayo: ukuphrinta kwesikrini, i-LPI, kanye ne-inkjet

I-Silkscreen isetshenziswa ngezindlela ezintathu eziyinhloko: ukuphrinta kwesikrini kwendabuko (uyinki ocindezelwe nge-stencil), ukuthwebula izithombe ngoketshezi (i-LPI, uyinki othuthukiswe ngesithombe ukuze uthole imininingwane emincane), kanye nokuphrinta nge-inkjet (okuphrintiwe ngedijithali, okuhle kumbhalo omncane kanye nedatha eguquguqukayo). Le ndlela isetha isinqumo esingafinyeleleka kanye nosayizi omncane wesici, yingakho isebenzisana nemithetho yokuklama engenhla:

• Ukuphrinta kwesikrini isunduza uyinki esikrinini esinephethini — eshibhile futhi evamile, kodwa eyinkimbinkimbi, ngakho idinga umbhalo omncane kanye nobubanzi bemigqa obukhulu.
• Ukuthwebula izithombe zoketshezi (LPI) amajazi nesithombe- kuthuthukisa uyinki ukuze kube nesisombululo esiphezulu kanye nombhalo ocolekile nobukhali, ofanele amabhodi aminyene.
• Inkjet iphrinta inganekwane ngedijithali ngaphandle kwesikrini, inikeza imininingwane emihle kanye nekhono lokushintsha okuqukethwe ebhodini ngalinye, okuhlobene Ukuphrinta kwe-inkjet ye-PCB.

Izindlela zokuxazulula okuphezulu zivumela umbhalo omncane, obukhali, okubalulekile emabhodini esimanje aminyene lapho isikhala senganekwane sincane. Indlela efanele incike ekutheni isikrini se-silkscreen sidinga ukuba sihle kangakanani kanye nobukhulu bebhodi, ukuze lihambisane nomklamo kunokuba lilungiswe — futhi linquma umbhalo omncane kanye nobubanzi bomugqa ongathembela kuwo.

6. Indlela i-Highleap ekhiqiza ngayo isikrini sesilika esihlanzekile nesifundekayo

I-Highleap ikhiqiza isikrini sesilika esihlanzekile nesifundekayo ngokufanisa indlela yokusebenzisa nezidingo zemininingwane yebhodi, ibambe umbhalo omncane kanye nobubanzi bemigqa, futhi ihlanganisa umbala wesikrini sesilika nemaski ye-solder ukuze kube nomehluko omkhulu. Inganekwane iphrintiwe ngaphandle kwama-pad nama-via, kanye nezimpawu zokubhekisela, amamaki e-polarity, kanye nombhalo wokubuyekeza owenziwe ngokucijile ukuze ibhodi kube lula ukuyihlanganisa, ukuyihlola, kanye nokuyisevisa.

Ngenxa yokuthi ikhwalithi yesikrini sesilika kanye nokubekwa kwaso kuthinta ukunemba kokwakhiwa, isibuyekezo sokwenziwa sihlola inganekwane ukuthi iyafundeka yini, i-pad clearance, kanye nanoma yimaphi amamaki inqubo yokwenziwa engawanciphisa - ibamba izinkinga ngaphambi kokuba ibhodi lenziwe. I-Highleap isingatha lokhu ngaphakathi kokukhiqiza kwe-PCB futhi isekela ibhodi elinabantu abaningi ngokusebenzisa i-turnkey assembly , lapho abaklami abacacile besheshisa ukubekwa nokuhlolwa. Uma ucela ikhotheshini, chaza imibala yesikrini sesilika kanye ne-solder-mask, noma yiziphi izidingo zombhalo omncane, nokuthi ngabe udinga amamaki akhethekile noma idatha yebhodi ngalinye ukuze inganekwane ikhiqizwe kahle.

7. Imibuzo Evame Ukubuzwa Ngesikrini Se-PCB Silkscreen

Iyini i-silkscreen layer ku-PCB?

Iphethe umbhalo ophrintiwe kanye nezimpawu — izichazi-magama zokubhekisela, amamaki e-polarity kanye ne-pin-one, igama lebhodi kanye nokubuyekezwa, ama-logo, kanye nezixwayiso — ukwenza ibhodi lifundeke kalula ukuze lihlanganiswe, lihlolwe, futhi lisetshenziselwe. Ayinawo umsebenzi kagesi.

Ungakanani usayizi wombhalo wesikrini se-silkscreen ophansi ku-PCB?

Kuncike endleleni yokusebenzisa kanye nekhono lomenzi, kodwa uhlamvu ngalunye ludinga ukuphakama okuncane kanye nobubanzi bomugqa ukuze luhlale lufundeka. Bhala umbhalo ongaphansi kwalowo mhlathi omncane uyaphuka noma uyaphuka, ngakho-ke qinisekisa umkhawulo nomkhiqizi wakho.

Ingabe i-silkscreen ingadlula ama-pad noma ama-via?

Cha — uyinki okwi-solderable pads uphazamisa ukusonta futhi ungabangela amaphutha, kanti uyinki okwi-vias awunyathelisi kahle. Gcina isikrini sesilika sikude nama-pads, insimbi eveziwe, kanye nezimbobo; abenzi bezinto bavame ukusika uyinki ophula lokhu.

Yimuphi umbala wesikrini sesilika ongcono kakhulu?

Leyo enokugqama okukhulu uma iqhathaniswa nemaski yakho ye-solder. Okumhlophe kujwayelekile futhi kufundeka kahle kokuluhlaza noma okumnyama; kumaski omhlophe, kusetshenziswa isikrini sesilika esimnyama. Gwema ukuhlanganiswa okufanayo lapho umbhalo unyamalala khona.

Kungani ezinye zesikrini sami sesilika zingekho ebhodini eliqediwe?

Ngokuvamile ngoba umbhalo noma imigqa yayingaphansi kosayizi omncane, noma uyinki wawufika kumaphedi noma kuma-via futhi wawuncishisiwe ngenqubo yokwenziwa. Ukuklama ngaphakathi kwemithetho encane yombhalo/umugqa kanye nokugcina kude namaphedi kuvimbela lokhu.

Ngingakwazi yini ukuphrinta ikhodi ye-QR noma ilogo kusikrini se-silkscreen?

Yebo — ama-logo nezithombe ezilungisiwe ziphrintwa kahle ku-silkscreen, futhi ikhodi elungisiwe (engeyona eyingqayizivele) ingafakwa. Kumakhodi ahlukile ebhodini ngalinye kanye nokwenza i-serialization, kusetshenziswa uphawu lwe-laser noma lwe-inkjet esikhundleni salokho, njengoba i-silkscreen iphrinta isithombe esifanayo ebhodini ngalinye.
