1. Anti-static

Iyo fekitori yekusangana yekuratidzira inofanirwa kunge iine yakanaka anti-static matanho.Dedicated anti-static ground, anti-static floor, anti-static soldering iron, anti-static table mat, anti-static ring, anti-static zvipfeko, kudzora humidity, kudzika midziyo (kunyanya mucheki wetsoka), nezvimwe zvose zvinokosha. zvinodiwa, uye zvinofanirwa kuongororwa nguva nenguva ne static mita .

2. Dhiraivha dhizaini dhizaini

Kurongeka kwemutyairi IC pane mutyairi wedunhu bhodhi pane yekuratidzira module inozokanganisawo kupenya kwe LED.Sezvo inobuda ikozvino yemutyairi IC ichifambiswa kureba paPCB board, kudonha kwevoltage yenzira yekutapurirana kuchave kwakakurisa, izvo zvinokanganisa yakajairika yekushanda voltage yeLED uye kuita kuti kupenya kwayo kuderere.Isu tinowanzoona kuti kupenya kwema LED kwakatenderedza modhi yekuratidzira kwakadzikira pane yepakati, ndicho chikonzero.Naizvozvo, kuti ive nechokwadi chekuenderana kweiyo yekuratidzira skrini kupenya, zvinodikanwa kugadzira mutyairi wedunhu rekugovera dhizaini.

3. Gadzira kukosha kwezvino

Iyo yezita ikozvino ye LED ndeye 20mA.Kazhinji, zvinokurudzirwa kuti huwandu hwekushanda huripo huve husingapfuuri 80% yehuwandu hwezita.Kunyanya kune zviratidziro zvine diki dot pitch, kukosha kwazvino kunofanirwa kudzikiswa nekuda kwemamiriro asina kunaka ekupisa kupisa.Zvinoenderana neruzivo, nekuda kwekusawirirana kweattenuation yekumhanyisa kweiyo tsvuku, girinhi, uye yebhuruu maLED, kukosha kwazvino kwebhuruu uye girinhi LEDs kunofanirwa kuderedzwa nenzira yakanangwa kuchengetedza kuenderana kweyero chena yeratidziro skrini. mushure mekushandisa kwenguva refu.

4. Zviedza zvakasanganiswa

MaLED eruvara rwakafanana uye mazinga ekupenya akasiyana anofanirwa kusanganiswa, kana kuisirwa zvinoenderana nedhiyagiramu yekuisa mwenje yakagadzirirwa zvinoenderana nemutemo wakasarudzika kuti ive nechokwadi chekuenderana kwekupenya kwemavara ega ega pachiratidziro chose.Kana paine dambudziko mukuita uku, kupenya kwenzvimbo yekuratidzira kuchave kusingawirirani, izvo zvinokanganisa zvakananga kuratidzwa kwekuratidzira kwe LED.

5. Dzora verticality yerambi

Kune-in-line LEDs, panofanirwa kuve neyakakwana process tekinoroji kuve nechokwadi chekuti iyo LED iri perpendicular kune PCB board kana ichipfuura nechoto.Chero kutsauka kunokanganisa kupenya kweiyo LED yakaiswa, uye mavara emavara ane kupenya kusingaenderane achaonekwa.

6. Wave soldering tembiricha uye nguva

Kupisa uye nguva yewave front welding inofanira kunyatsodzorwa.Zvinokurudzirwa kuti preheating tembiricha iri 100 ℃ ± 5 ℃, uye tembiricha yepamusoro haifanire kudarika 120 ℃, uye tembiricha yekupisa inofanira kukwira zvakanaka.Welding tembiricha ndeye 245 ℃ ± 5 ℃.Zvinokurudzirwa kuti nguva isapfuure masekonzi matatu, uye usadedera kana kuvhundutsa iyo LED mushure mechoto kusvika yadzokera kune yakajairika tembiricha.Iwo tembiricha ma paramita emuchina weave soldering anofanirwa kutariswa nguva nenguva, iyo inotarwa nehunhu hweiyo LED.Kupisa kana kuchinjika tembiricha inokuvadza zvakananga iyo LED kana kukonzera yakavanzika mhando matambudziko, kunyanya kune madiki-saizi kutenderera uye oval LEDs se3mm.

7. Welding control

Kana kuratidzwa kwe LED kusingavheneke, pane kazhinji kanopfuura 50% mukana wekuti inokonzerwa nemhando dzakasiyana-siyana dzekutengesa, dzakadai se LED pin soldering, IC pin soldering, pin header soldering, nezvimwewo. Kuvandudzwa kwezvinetso izvi kunoda. kunatsiridza kwakasimba kwemaitiro uye kusimbiswa kwemhando yekuongorora kugadzirisa.Iyo vibration bvunzo isati yabuda mufekitori zvakare inzira yakanaka yekuongorora.

8. Dhizaini yekupisa kupisa

LED inoburitsa kupisa kana ichishanda, tembiricha yakawandisa inokanganisa kukurumidza uye kugadzikana kweLED, saka dhizaini yekupisa yekupisa yePCB board uye kufefetedza nekupisa kupisa dhizaini yekabati kuchakanganisa mashandiro eLED.
