Niki Silkscreen Kuri PCB?
Mugihe ushushanya cyangwa gutumiza ibyawe icyapa cyumuzingo , ukeneye kwishyura inyongera kuri silkscreen?Hano haribibazo bimwe bimwe ukeneye kumenya silkcreen?Nuburyo ki silkscreen ifite akamaro muriwe Guhimba Ubuyobozi bwa PCB cyangwa Iteraniro ryinama yumuzunguruko ?Noneho ABIS izagusobanurira.
Ikirangantego ni iki?
Silkscreen ni urwego rwa wino rukoreshwa mukumenya ibice, amanota yikizamini, ibice bya PCB, ibimenyetso byo kuburira, ibirango nibimenyetso nibindi. Iyi ecran ya silike isanzwe ikoreshwa kuruhande rwibigize;icyakora gukoresha silkscreen kuruhande rwabagurisha nabyo ntibisanzwe.Ariko ibi birashobora kongera ikiguzi.Mubyukuri PCB idasobanutse ya PCB irashobora gufasha uwabikoze na injeniyeri kumenya no kumenya ibice byose.
Irangi ni wino idakora neza.Irangi ryakoreshejwe kuri ibyo bimenyetso ryakozwe cyane.Amabara asanzwe tubona ni umukara, umweru n'umuhondo.Porogaramu ya PCB ikoresha kandi imyandikire isanzwe mubice bya silkscreen ariko urashobora guhitamo indi myandikire muri sisitemu.Kugirango ubudodo bwa silike-gakondo ukenera ecran ya polyester irambuye kumurongo wa aluminium, umushinga wamafoto ya laser, utera spray hamwe nitanura.
Ni iki kizagira ingaruka kuri silike?
Viscosity: Viscosity bivuga kugenda ugereranije hagati yamazi yegeranye mugihe ayo mazi atemba, noneho hazavamo imbaraga zo guterana amagambo hagati yibice byombi byamazi;igice: Amasegonda ya Pascal (pa.s).
Gukomera: Ubukomezi bwa wino nyuma yo guteka mbere ya 2B, ubukana bwa wino nyuma yo kugaragara ni 2H, naho ubukana bwa wino nyuma yo guteka ni 6H.Ikaramu. Thixotropic: wino iba gelatinous iyo ihagaze, ariko viscosity ihinduka iyo ikozweho, izwi kandi nka thixotropique, anti-sagging;ni umutungo wumubiri wamazi, ni ukuvuga, muburyo bwo gukurura ububobere bwayo bugabanuka, kandi bigahita bigarura imiterere yambere yumwijima nyuma yo kwemererwa guhagarara.Binyuze mu gukurura, ingaruka za thixotropy zimara igihe kirekire, zihagije zo kubaka imiterere yimbere.Kugirango ugere kumurongo wohejuru wo gucapura ibisubizo, thixotropy ya wino ni ngombwa cyane.Cyane cyane mugikorwa cyo gukanda, wino irahinda umushyitsi kugirango ikorwe.Ingaruka yihutisha umuvuduko wa wino unyura muri mesh, kandi uteza imbere ihuza rimwe rya wino yatandukanijwe na mesh.Iyo igikoma kimaze guhagarika kugenda, wino isubira muburyo buhagaze, kandi ubwiza bwayo bugaruka vuba kumakuru asabwa. Filime yumye: Imiterere ya firime yumye:
Filime yumye igizwe nibice bitatu nibigize:
Shigikira firime (film ya polyester, Polyester)
Ifoto-irwanya Firime Yumye
Igifuniko cya firime (film ya polyethylene, Polyethylene)
Ibyingenzi
Inder Guhuza binder (resin ikora firime),
HFoto-polymerisation monomer Monomer,
③Foto-yatangije,
LasticPlastiser,
PromIterambere rya Adhesion,
InhibIbikoresho bya polimerisiyumu yubushyuhe,
Irangi ryamabara,
⑧
Ubwoko bwa firime yumye igabanijwemo ibyiciro bitatu ukurikije uburyo bwa firime yumye hamwe nuburyo bwo kuyikuraho: firime yumye ishingiye kumashanyarazi, firime yumye yumye na firime yumye;ukurikije intego ya firime yumye, igabanijwemo: kurwanya firime yumye, masike yumye ya mask hamwe na firime yumye ya Solder.
Umuvuduko wibyiyumvo: bivuga ubwinshi bwingufu zumucyo zisabwa kugirango uwifotora ashobore gukora polymerize kugirango akore polymer hamwe nuburwanya runaka bwo kurwanya munsi yumucyo wumucyo ultraviolet, ukurikije imiterere yumucyo uhamye nuburebure bwamatara, Umuvuduko ukabije ni bigaragazwa nkuburebure bwigihe cyo kwerekana, igihe gito cyo kwerekana bisobanura umuvuduko ukabije.
Igisubizo: bivuga umubare wimirongo (cyangwa intera) ishobora gukorwa na firime yumye irwanya intera ya 1mm.Imyanzuro irashobora kandi kugaragazwa nubunini bwuzuye bwimirongo (cyangwa intera).
Urudodo rwiza:
Ubucucike bwuzuye:
T umubare: bivuga umubare wa meshes muburebure bwa cm 1.
