Baarakɛla misali ni fɛn dilanni sira sabatilen cɛ, danfara bɛ yen mɔgɔ si tɛ se ka min ye. Piloti boli bɛ yen walasa ka taama a kan ni sɔngɔ gɛlɛn ye i n’a fɔ a bɛ se ka kɛ cogo min na.

I tɛ se ka yɔrɔ min ye, o sigilen bɛ Sample ni Volume cɛ

Misali bɛ baara kɛ. A bɛ yeelen bɔ, a ka kan ka min kɛ, a bɛ o kɛ, wa ekipu caman bɛ daminɛ ka boloda hakɛ la. Nka danfara lakika bɛ sigi sample ni production cɛ. Sample ye fɛɛrɛtigi ye min bɛ yɔrɔw ta bolo la ani ka u ladilan ka ɲɛ; production ye masinw ye minnu bɛ boli ka takt waati. Sample ye unit kelen ye; bɔli ye ba caman ye minnu ka kan ka bɛn.

Piloti boli bɛ yen walasa ka o yɔrɔ in taama wari fitinin na. Fɛn min ka kan ka minɛ, o ye ko piloti boli tɛ bɔli ye hakɛ dɔgɔyalen na. Fɛn min ka kan ka dɔgɔya, o ye hakɛ ye, a tɛ taabolo ye. Skip a check ani pilot ye dɔrɔn repetition saralen ye batch of boards min bɛna mago don rework la cogo o cogo.

Sɛgɛsɛgɛlikɛyɔrɔ fɔlɔ: DFM seginnkanni

Sani layini ka kɛ, aw bɛ a dilanni kɛcogo lajɛ. Yala pad dilancogo bɛnnen don, stencil dakunw ka kan ka da wuli cogo di, ni component orientations friendly to placement, ni test points maralen don, yala clearance bɛ yen through-hole yɔrɔw kama wa.

Sɛgɛsɛgɛlikɛyɔrɔ fila ni saba: Barokun fɔlɔ ani Sɛgɛsɛgɛli dafalen

Board fɔlɔ min bɔra layini na, o tɛ yamaruya ye ka boli. Barokun fɔlɔ sɛgɛsɛgɛli bɛ hakɛw, solder joints, component references ani polarity sɛgɛsɛgɛ, ani k’a jira ko minɛnw ni porogaramu bɛ cogo bɛnnen na sani u ka bɔli kɛ ka taa a fɛ. O sen in bɛ batch bɛɛ bali ka wuli, a bɛ se ka fɔ ko a musaka tɛ foyi ye, wa a nafa ka bon kosɛbɛ.

O kɔfɛ, sɛgɛsɛgɛli bɛ fa sanni ka kɛ misali ta ye. Solder joints bɛɛ bɛ tɛmɛ automatique optique inspection (AOI) fɛ, joints dogolenw i n’a fɔ BGA bɛ X-ray fara a kan, ani flying-probe ani functional test yɔrɔ minnu mago bɛ a la. Koman fitininw bɛ sɔngɔko jateminɛ, o min bɛ mɔgɔw kɔrɔbɔ k’a ɲininka ni sɛgɛsɛgɛliw bɛ se ka bila — o kɔfɛko ye tiɲɛ ye.

Sɛgɛsɛgɛli yɔrɔ naaninan: Sɛgɛsɛgɛli bɔli ani lopu datuguli

Da laban ye pakew ni bɔli sɛgɛsɛgɛli ye. Sɛgɛsɛgɛli ɲɛnama kɔfɛ, OQC bɛ na, min bɛ hakɛ, taamasiyɛnw, pakew dilanni fɛɛrɛ ani baarakɛcogo misali dɔ dafa. O waati kelen na, ko minnu bɛ sɔrɔ piloti boli waati la, olu bɛ sɛbɛn : solder joints jumɛnw ka teli ka nɛnɛ, placement offset bɛ boli yɔrɔ minnu na ka bon, station jumɛn ka gɛlɛn takt kan — wa o dantigɛliw bɛ segin ka don production parameters kɔnɔ. Ni conformal coating, full assembly ani functional test bɛɛ kɛra jiri kelen kɔnɔ, o feedback loop bɛ surunya; jɛnsɛnnen butiki caman kɔnɔ , dantigɛli bɛ se jama caman yeli kɔfɛ .

An ka izini bɛ sampling, batch fitininw ani volume production to izini kelen kɔnɔ, ni pilote ni volume bɛ kɛ mɔgɔ kelenw fɛ ka kɛɲɛ ni paramètre kelenw ye.
