Kudonha uye chando inguva dzakakwirira dzekukundikana kwemidziyo yemagetsi, uye ma LED skrini haana mutsauko.Seyakakwirira-kukosha chaiyo zvigadzirwa zvemagetsi, maitiro ekuita basa rakanaka mumatsutso uye munguva yechando LED kuratidza kugadzirisa, kunze kwekudikanwa kwekuita basa rakanaka rekugadzirisa zvakajairika, asi zvakare inofanirwa kubhadhara zvakanyanya kune zvinotevera zvinhu zvitatu. : static magetsi, condensation uye yakaderera tembiricha.
Electrostatic dziviriro yakakosha, kuita basa rakanaka rekudzivirira kwemagetsi kunofanirwa kunzwisisa kwakabva magetsi akamira.Zvinoenderana nedzidziso yeatomic fizikisi, zvinhu zviri mumagetsi equilibrium kana isiri yemagetsi.Nekuda kwekuwana uye kurasikirwa kwemaerekitironi anogadzirwa nekusangana kwezvinhu zvakasiyana, zvinhu zvinorasikirwa nemagetsi uye zvinogadzira electrostatic phenomenon.Kukakavadzana pakati pemiviri kunounza kupisa uye kunofadza kufambiswa kweerekitironi;Kusangana uye kupatsanurwa pakati pemitumbi inoburitsa maelectron transfer;Electromagnetic induction inoguma nekusaenzana kugovera kwechaji pamusoro pechinhu.Iyo yakasanganiswa mhedzisiro yekukwenya uye electromagnetic induction.
Static magetsi imhondi hombe yekuratidzira kwe LED, kwete chete inoderedza hupenyu hwechiratidziro, asi zvakare ichaburitsa kuparara kuratidza mukati memagetsi zvikamu, kukuvadza skrini.Ingave yemukati ye LED kuratidza kana yekunze ye LED kuratidza, zviri nyore kugadzira magetsi akamira mukushandiswa, zvichikonzera njodzi dzekuchengetedza kuchiratidziro.Electrostatic dziviriro: Grounding ndiyo yakanakisa anti-static nzira mukugadzira maitiro, vashandi vanofanirwa kupfeka grounding electrostatic bracelet.Kunyanya mukugadzirisa tsoka, plug-in, debugging uye post welding, uye kuita kutarisa kwakanaka, vashandi vehutano vanofanira kuita static test yebracelet kwemaawa maviri oga oga;Vashandi vanosungirwa kupfeka mabhureki epasi panguva yekugadzira.Kunyanya mukugadzirisa tsoka, plug-in, debugging uye post welding, uye kuita kutarisa kwakanaka, vashandi vehutano vanofanira kuita static test yebracelet kwemaawa maviri oga oga;Shandisa yakaderera voltage DC mota mutyairi newaya yepasi pese pazvinogoneka panguva yekuungana.
Condensation zvakare inotyisa kuratidzwa kweLED, uye kukuvadza kukuru kune kuratidzwa kwekunze.Kunyangwe zvidzitiro zvekunze zvichiitwa kusapinda mvura, condensation inokonzerwa nekudzika kwemhute yemvura kubva kumhepo, uye madonhwe madiki anogona kubatirira kuPCB board uye module nzvimbo dzekuratidzira.Kana iyo isina mvura kurapwa ikasaitwa nemazvo, iyo PCB board uye module ichave yakasvibiswa, zvichikonzera kuderedzwa kwehupenyu kana kukuvadzwa kweiyo LED kuratidzwa.Mhinduro ndeyekusarudza chidzitiro chekuvhara mvura kana uchitenga chidzitiro chekuratidzira, senge nyore kusvika kune Helios nhevedzano, kana kune chidzitiro chemuviri chakaputirwa nejira rematatu anti pendi.
Yakadzika tembiricha nharaunda inokanganisawo kushanda kwe LED kuratidzwa, yakawanda yekunze LED inoratidzira tembiricha iri -20 ℃ kusvika 60 ℃, yakaderera tembiricha inotungamira kune chiitiko chezvimwe semiconductor zvikamu zvakaderedzwa, kana kutotadza kutanga zvakajairika, uye mamwe epurasitiki. zvikamu zvinogona kutsemuka nekuda kwekuderera kwekushisa.Naizvozvo, kana uchitenga LED yekuratidzira skrini, edza kuterera tembiricha yayo yekushanda, usavheneke iyo LED skrini kana tembiricha yakadzikira, uye gara uchitarisa kana iyo skrini yakakuvadzwa, kana kutonhora kwakanyanya kunogona kuwedzerwa skrini ine mudziyo unodziya wemhepo.
Aya mapoinzi matatu ari pamusoro inguva yekuvhuvhu uye yechando, LED kuratidza kugadzirisa kunoda kutariswa.
