PCBA Processing Pads Sali Pa Kusanthula Chifukwa Cha Tin

PCBA processing amatchedwanso Chip processing, zambiri chapamwamba wosanjikiza amatchedwa SMT processing, SMT processing, kuphatikizapo SMD, DIP pulagi-mu, pambuyo solder mayeso ndi njira zina, mutu wa ziyangoyango si pa malata makamaka mu SMD processing ulalo, phala wodzaza zigawo zosiyanasiyana za bolodi ndi kusanduka kuchokera PCB kuwala bolodi, pcb kuwala bolodi ali zambiri ziyangoyango (kuyika kwa zigawo zosiyanasiyana), kudzera-dzenje (pulagi-mu), ziyangoyango si malata. zikuchitika pano Zinthu ndizochepa, koma mu SMT mkati mulinso gulu lamavuto apamwamba.
Mavuto a ndondomeko ya khalidwe, ayenera kukhala zifukwa zingapo, muzochitika zenizeni zopangira, ziyenera kukhazikitsidwa pazochitika zoyenera kuti zitsimikizire, mmodzimmodzi kuthetsa, kupeza gwero la vuto ndi kuthetsa.

I. Kusungirako kolakwika kwa PCB

Nthawi zambiri, malata opopera pa sabata adzawoneka ngati okosijeni, mankhwala a OSP amatha kusungidwa kwa miyezi itatu, mbale yagolide yomira imatha kusungidwa kwa nthawi yayitali (pakali pano njira zopangira PCB nthawi zambiri)

II.Kuchita molakwika

Njira yolakwika yowotcherera, mphamvu yotentha yosakwanira, kutentha kosakwanira, nthawi yokwanira yobwereranso ndi zovuta zina.

III.Mavuto a mapangidwe a PCB

Solder pad ndi njira yolumikizira khungu yamkuwa ipangitsa kuti pad ikhale yosakwanira kutentha.

IV.Vuto la flux

Flux ntchito sikokwanira, PCB ziyangoyango ndi zigawo zamagetsi soldering pang'ono sachotsa makutidwe ndi okosijeni zakuthupi, solder olowa pang'onopang'ono flux sikokwanira, chifukwa kunyowetsa osauka, kutulutsa mu malata ufa si analimbikitsa mokwanira, kulephera Integrated mu flux. (phala la solder kubwerera ku nthawi ya kutentha ndi lalifupi)

V. PCB bolodi lokha vuto.

PCB bolodi mu fakitale pamaso PAD pamwamba makutidwe ndi okosijeni si mankhwala
 
VI.Reflow uvunimavuto

Nthawi yotenthetsera ndi yayifupi kwambiri, kutentha kumakhala kochepa, malata sanasungunuke, kapena nthawi yotenthetsera ndi yayitali kwambiri, kutentha kumakhala kokwera kwambiri, zomwe zimapangitsa kuti ntchito ya flux iwonongeke.

Kuchokera pazifukwa zomwe tafotokozazi, PCBA processing ndi mtundu wa ntchito sangakhale wosasamala, sitepe iliyonse iyenera kukhala yokhwima, mwinamwake pali chiwerengero chachikulu cha mavuto apamwamba mu mayeso a pambuyo pake kuwotcherera, ndiye zidzachititsa chiwerengero chachikulu kwambiri cha anthu, ndalama ndi zinthu zomvetsa, kotero PCBA processing pamaso mayeso woyamba ndi chidutswa choyamba cha SMD n'kofunika.
