Non nefinen ew sample mi angang me ew linein for pisek mi nukuchar mi wor ew gap ese wor emon epwe tongeni kuna. Ew pilot run a nomw pwe epwe fetan won ren ukukun an tufich.

Eú Gap Kose tongeni kúna a nóm lefilen ewe Sample me ewe Volume .

Ewe sample a angang. A saramaram, a fori met epwe fori, me chommong team ra poputa ne kokkot ngeni volume. Nge eu wesewesen kinikinfesen a nom lefilen sample me foruta. Ewe sample ina emon chon angang mi angei ekkewe kinikin ren poun me a awenecharaoch; pworousen ekkewe misineri ra fiti takt fansoun. Ewe sample ina ew unit; pworous mi fite puku mi namwot epwe match. Ekkewe rese nukuchar mi fis non kinamwe mi fis non ewe kinikinin sample ra niwinsefan non fansoun ewe angang a fis non ew napanap mi otot.

Ew pilot run a nomw pwe epwe fetan non ena gap ren ewe moni mi kukkun. Ewe mettoch sipwe amwochu pwe eu pilot run esapw ew angangen for pisek non ew ukukun mi kukkun. Met epwe kisikisilo, ina chochoon, nge esap fofforun. Skip ew chek me ewe pilot a chok ew angangen afanafan mi kamo ren ew mwichen board epwe namwot epwe angang sefan ese nifinifin. Ekkei fomon chekin fan ina ewe mwichen ach plant a wesewesen fori won ekkewe kukkun-batch order.

Cheki Ew: DFM Nengeni .

Me mwen ewe line, kopwe fori ew angangen nengeni. Itá mi pwúng ekkewe kókkótun pad, ifa usun epwe suk ekkewe asam ngeni ewe stencil, ika ekkewe kinikin ra chék chéúfetál, ika ekkewe leenien tes ra fen kefilitá, ika mi wor leenien ffér fán iten ekkewe kinikin mi chéúfetál lón ekkewe chénúpupu. Ew me ew ekkei a kamo ew awa an epwe fix non ewe fansoun design; won ewe line epwe tongeni wewe ngeni an epwe atai ew puun, niwinsefaniti ew stencil, ika atai ew batch.

Ewe auchean DFM ina an epwe affouni ewe ekiekin design ngeni fosun angang. Ewe chon forata a ekieki usun angang me angangoch; ewe chon fori ewe angang a ekieki ika epwe tongeni forsefal. Nupwen ekkewe ruemon ra fori ewe poraus fan ew, chommong mwirin angang sefan ese fis. Ren ekkewe kukkun mwich ei a kon auchea — ese wor volume epwe amortise ewe monien angang won ewe angang.

Cheki Ruu me Unungat: Aewin Kinikin me Unusen Inspection .

Ewe aewin board seni ewe line esapw mumuta an epwe run. Ewe aewin kinikin a annetata ekkewe ukukun, ekkewe ririin solder, ekkewe pisekin angang me polarity, me a annetata pwe ekkewe pisek me prokram ra nom non ew napanap mi pung me mwen an epwe fis ewe angangen forata mi sopwosopwono. Ei mettoch a eppeti unusen eu batch seni an epwe kkuf, arapakan ese wor liwinin, me a fokkun auchea.

Mwirin ena, inspection a uren nap seni sample. Meinisin ekkewe minen alillis ra kan fiti ewe angangen nengeni (AOI), ekkewe minen alillis mi monomon ussun chok BGA ra apachalong X-ray, me ekkewe minen alillis mi fiti fitikoko me angangen fitikoko ikewe mi lamot ie. Ekkewe kukkun-batch order ra kan fiti niwinin, minne a sotuni aramas ar repwe eis ika ekkewe test ra tongeni katonong — ewe opposun a ennet.
