PCBA board inspection standards and precautions

PCBA board PCBA board inspection standards?

I. PCB board kuyendera miyezo

1. Zowonongeka kwambiri (zofotokozedwa ngati CR): zolakwika zilizonse zomwe zimakhala zokwanira kuvulaza thupi la munthu kapena makina kapena kuika pangozi chitetezo cha moyo, monga: kusatsatira malamulo a chitetezo / kuwotcha / kugwedezeka kwa magetsi.

2. Zowonongeka Zazikulu (zotchulidwa MA): Zowonongeka zomwe zingayambitse kuwonongeka kwa mankhwala, ntchito zosazolowereka, kapena kusokoneza moyo wautumiki wa mankhwala chifukwa cha zipangizo.

3. Zowonongeka zazing'ono (zofotokozedwa ngati MI): sizimakhudza ntchito ndi moyo wautumiki wa mankhwala, pali zolakwika zodzikongoletsera ndi zolakwika zazing'ono kapena zosiyana pa msonkhano wa makina.

II.Mikhalidwe yoyendera gulu la PCBA

1. pofuna kupewa kuipitsidwa kwa zigawo kapena zigawo, muyenera kusankha magolovesi kapena magolovesi chala ndi chitetezo EOS / ESD, ndi ntchito electrostatic mphete ntchito.Gwero la kuwala ndi nyali yoyera ya fulorosenti.Kuwala kowala kuyenera kukhala pamwamba pa 100Lux ndikuwoneka bwino mkati mwa masekondi 10.

2. Njira yoyang'anira: Ikani mankhwalawo pamtunda wa masentimita 40 kuchokera ku maso onse awiri, pafupifupi madigiri 45 mmwamba ndi pansi, ndipo yang'anani mowonekera kapena ndi galasi lokulitsa katatu.

3. Muyezo woyendera: (Sampling zochokera ku QS9000 C≥0 AQL = 0.4% sampling level; ngati makasitomala ali ndi zofunikira zapadera, malinga ndi kuvomereza kwa makasitomala).

4. Dongosolo lachitsanzo: mil-std-105 E mlingo 2 wamba sampling imodzi

5. Njira zopangira zisankho: zolakwika zazikulu (CR) AQL 0%

6. Kuipa Kwambiri(MA)AQL 0.4%

7. Secondary Inferiority(MI)-AQL-0.65%

Monga ena PCB bolodi kukula ndi yaing'ono, nthawi zambiri ntchito splicing njira, mu akamaliza PCBA msonkhano processing, m'pofunika kulekanitsa PCBA chithunzi.Kupatukana makamaka anawagawa Buku yaing'ono mapanelo ndi makina ang'onoang'ono mapanelo, mu ndondomeko ya sub-paning'a, ayenera kulabadira ena kusamala kupewa kuwonongeka wathunthu PCBA bolodi.

I. zofunika za gulu laling'ono lamanja

Mukamapinda m'mphepete mwa bolodi, muyenera kugwiritsa ntchito manja onse awiri kuti mugwire m'munsi mwa bolodi la PCB, kutali ndi V odulidwa pansi pa 20 mm kuti mupewe kupindika ndi kupunduka.

II.Zofunikira za board partition board

1. Khola lothandizira

Ngati palibe chithandizo, kupsinjika komwe kumabwerako kumatha kuwononga gawo lapansi ndi ma solder.Kusokoneza bolodi, kapena kukakamiza chigawocho panthawi yogawaniza, kungayambitse zolakwika zobisika kapena zoonekeratu.

2. Valani zida zodzitetezera

Pamaso ntchito, ayenera kukonzekera chitetezo, ayenera kukhazikitsa mkulu-pafupipafupi maso chitetezo kuyatsa chipangizo kuteteza chitetezo woyendetsa.Ndi bwino kubweretsanso magalasi kuti muteteze maso.

3. ayenera nthawi zambiri ntchito mowa misozi makina chida spindle ndi chida kuthetsa PCB fumbi kwaiye m`kati ziboda, kukhalabe ntchito yachibadwa ya ziboda.

4. Pambuyo pa nthawi zingapo zogwiritsira ntchito, muyenera kusalaza slider ndi mayendedwe a distribuerar ndikuyang'ana ngati zomangira zili zotayirira, ndi zina zotero.

5. Pogwiritsa ntchito makinawo, pamwamba pa tebulo ayenera kukhala oyera, ndi bwino kuti asaike zinthu zina, kuti apewe kuwonongeka kwa chida komanso zinthu chifukwa cha zinthu zomwe zili pachidacho zikugwa. .Ngakhale pali maso magetsi kukonza, koma m`kati ntchito, tcheru zala ndi zida kutsatira ena chitetezo imeneyi.
Ambiri, pamene ntchito ziboda PCBA, ziboda makina ndi kothandiza kwambiri ndi mlingo m'munsi kuwonongeka kuposa ziboda Buku.Komabe, pochita kugawanika kwa makina, m'pofunikanso kugwira ntchito motsatira ndondomekoyi kuti muchepetse zolakwika za anthu.

Zhejiang NeoDen Technology Co., LTD., yomwe idakhazikitsidwa mu 2010, ndi katswiri wopanga makina opangira ma SMT ndi malo, uvuni wa reflow, makina osindikizira a stencil, chingwe chopangira SMT ndi Zida zina za SMT.Tili ndi gulu lathu la R & D ndi fakitale yathu, kugwiritsa ntchito mwayi wathu olemera odziwa R&D, kupanga ophunzitsidwa bwino, adapambana mbiri yabwino kuchokera kwamakasitomala padziko lonse lapansi.

Timakhulupirira kuti anthu abwino ndi othandizana nawo amapangitsa NeoDen kukhala kampani yabwino komanso kuti kudzipereka kwathu ku Innovation, Diversity and Sustainability kumawonetsetsa kuti makina a SMT azitha kupezeka kwa aliyense wokonda zosangalatsa kulikonse.
