Izidingo Zamafayela Omhlangano We-PCB

Kwa- Highleap Electronics , amaphakheji aphelele amafayela avumela ukucutshungulwa okusheshayo kanye nemibuzo embalwa yobunjiniyela. Sisebenzisa i-Gerbers + drill yakho ukukhiqiza amathuluzi okukhiqiza, kanye nemidwebo yakho ye-BOM + pick-and-place + assembly ukuhlela ukubekwa kwe-SMT nokuqinisekisa i-polarity/orientation. Lo mhlahlandlela ukukusiza ukulungiselela idatha ehamba kahle ekukhiqizeni.

1) Iphakheji Yefayela Eliphelele

1.1 Uhlu Lokuhlola Amafayela Abalulekile

Kudingeka Njalo:

• ☐ Amafayela e-Gerber (zonke izendlalelo ziyadingeka ekwenzeni)
• ☐ Amafayela okubhoboza (ifomethi ye-Excellon)
• ☐ Uhlu Lwezinto Ezisetshenziswayo (BOM)
• ☐ Khetha bese ubeka ifayela le-centroid (ukubekwa kwengxenye)
• ☐ Umdwebo wokuhlanganisa (Phezulu/Phansi, i-polarity, ama-refdes)

Kudingeka Kaningi (kuye ngokuthi ibhodi kanye nokwakhiwa):

• ☐ Amanothi okudweba/okwenza izinto
• ☐ Imininingwane ye-stackup (ikakhulukazi ye-impedance noma i-dielectric elawulwayo)
• ☐ Izidingo zokuhlola (i-AOI/ICT/ezisebenzayo)
• ☐ Imiyalelo ekhethekile (ukuhlela, ukumboza, ukuphatha)
• ☐ Ulwazi lokufakwa kwamaphaneli (uma kufakwe amaphaneli noma kudinga ama-rails)

1.2 Ukuvumelana Kokubuyekezwa Kwefayela

Okubalulekile: Wonke amafayela kumele abe avela ekubuyekezweni okufanayo komklamo (ama-Gerber, i-drill, i-BOM, ukukhetha nokubeka, imidwebo).

Ukubuyekezwa okuxubile kuvame ukubangela:

• Izingxenye ezibekwe kuma-pad angalungile (izinyathelo zishintshiwe kodwa ifayela lokubekwa alibuyekezwanga)
• Ukungafani kwe-BOM/ukubekwa (izingxenye ezingekho noma inani elingalungile)
• Izinyathelo ezingalungile ezakhiwe (ukungalingani kwe-Gerber vs drawing vs BOM)

Indlela engcono kakhulu: faka isihlonzi sokubuyekeza kuwo wonke amagama amafayela namadokhumenti (isb., i-RevA / i-RevB, isitembu sosuku, inombolo ye-ECO).

2. Isibuyekezo samahhala se-DFM kwenziwa
3. Umbiko we-DFM enikeziwe
4. Imibuzo icacisiwe ngaphambi kokukhiqizwa
5. Ukukhiqizwa kuyaqhubeka ngedatha eqinisekisiwe

Amafayela aphelele, ahlelwe kahle asheshisa le nqubo. Buyekeza uhlu lwethu lokuhlola lwe-PCB DFM kanye nemithetho yokuklama ukuhlanganiswa ngaphambi kokuthumela.

Xhumana nethimba lethu lobunjiniyela uma unemibuzo mayelana nezidingo zefayela zephrojekthi yakho ethile.
