Chii chinofanira kubhadharwa pakusarudza yakanaka LED light bar

Izvo zvinofanirwa kutariswa pakusarudza yakanaka LED mwenje bhaa Iyo LED inopararira inoratidzira mwenje mitsetse yatiri kushandisa ikozvino yakasimba kwazvo uye inogara, uye yakajairika sherufu hupenyu hunosvika makore matatu. Chimiro chekusimba uye kusimba ndechekuti masisitimu anoenderana uye zvakatemwa zvinofanirwa kuteedzerwa zvakanyanya panguva yekugadzira. Inotevera inonyora iyo LED inopararira inoratidzira mwenje mitsetse panguva yekugadzira. Zvinhu zvekuteerera. 1. Chenjerera kune anti-static, uye inorambidzwa zvachose kubata PCB board pasina static dziviriro, izvo zvinogona kukonzera kukanganisa kune LED diffuse mwenje bhedhi. 2. Chenjerera kuti usabata lens pasina magirovhosi, izvo zvinokonzeresa zvigunwe pane lens.

Inokanganisa chiedza chemavara. 3. Nyatsocherechedza kana solder paste yakashandiswa yapera (kazhinji, solder paste mushure mekuvhura inoda kushandiswa mukati memaawa makumi maviri nemana), uye kunaka kwe solder paste kunofanira kuva kwakanaka. Neiyi nzira chete iyo hupenyu hwesevhisi ye LED inopararira yekuratidzira mwenje bar inovimbiswa.

4. Chenjerera kune glue inoporesa, unoda kuve nechokwadi kuti hutano hweglue hunofanira kuva hwakanaka. Iglue inorapa inogona kumira kupisa kwakanyanya. Kazhinji tembiricha ndeye 70-90 madhigirii. Nekuti mabhero emwenje anoburitsa tembiricha paanenge achishandiswa.

Kana iyo glue yekurapa isingakwanise kumira kupisa kwakanyanya, ichaita kuti lenzi iwire pasi. 5. Cherechedza kuti lens ye LED diffuse reflection light bar inofanira kuiswa panzvimbo, uye kureba pakati pe lens nePCB board haifaniri kunge yakakura kudarika 0.1mm. 6. Cherechedza kuti lens ye LED diffuse reflection light bar haigoni kuderedzwa.

(Angle of inclination haigoni kudarika 1 ° C) 7. Kuchengetedza kwekuiswa kweSMT, iyo SMT yekuisa muchina inofanira kugadzirisa data yemarambi mabhesi uye resistors. Hapanofanira kunge paine skewing. 8. Ziva kuti tembiricha ye reflow soldering inofanira kudzorwa zvine musoro, zvikasadaro ichakanganisa mabhedhi emwenje e LED.

9. Paunenge uchipa glue, unofanirwa kudzora huwandu hweglue inopihwa. Iyo haigone kudarika pamusoro pePCB board ye LED diffuse reflection light strip. 10. Ziva kuti kurongedza kunofanirwa kubatwa pasi pe-anti-static michina.

Uyezve, PE anti-static mabhegi anoshandiswa kurongedza obva aiswa mumakatoni.
