Stat long Prototaip i go long Prodaksen: 4-pela Sekpoint insait long wanpela Pailot Ran

Stori

Septemba 12, 2024

Namel long wanpela wok sempel na wanpela stebol prodaksen lain i gat wanpela spes we nogat wanpela man inap lukim. Wanpela 'pilot run' i stap bilong wokabaut long en long liklik pe tasol.

Wanpela spes we yu no inap lukim i stap namel long sampela na volium

Sampol i wok. Em i lait, em i mekim wanem samting em i mas mekim, na planti tim i stat long plenim volium. Tasol i gat bikpela spes namel long 'sample' na 'production'. Sampol em i wanpela teknisen i save kisim ol hap bilong en na stretim gut; prodaksen em ol masin we i wok long taim stret. Sampol em i wanpela yunit; prodaksen em planti tausen we i mas wankain. Ol samting we i no klia we i save kamap taim ol i holim isi isi long 'sample stage' i save kam bek nating taim proses i wok long ron long otomatik spit.

Wanpela pailot ran i stap bilong wokabaut long dispela spes long liklik mani tasol. Poin bilong holim em olsem wanpela 'pilot run' em i no prodaksen long liklik mak. Samting we ol i mas daunim em namba, i no pasin bilong mekim wok. Noken sekim na pailot em i wanpela 'rehearsal' we ol i baim long wanpela lain bod we bai nidim wok gen. Dispela 4-pela 'checkpoint' aninit em ol 'sequence' we plent bilong mipela i save mekim long ol liklik oda.

Sekpoint Wan: DFM Riviu

Pastaim long lain, ranim wanpela riviu bilong wokim ol samting. Ol disain bilong ol 'pad' i stret, olsem wanem ol i mas opim ol 'stencil apertures', ol 'component orientations' i gutpela long putim, ol i bin makim ol 'test points', i gat spes bilong putim ol 'through-hole' hap. Wanwan bilong ol dispela i save kostim wanpela aua long stretim long taim bilong disain; long lain em i ken min olsem rausim wanpela bod, katim gen wanpela stensil, o rausim wanpela 'batch'.

Value bilong DFM em long tanim tingting bilong disain i go long tokples bilong proses. Disaina i tingim wok na pefomens; 'process engineer' i save tingim sapos ol i ken wokim planti taim o nogat. Taim tupela i toktok wanpela taim, planti wok gen bihain i no save kamap. Long ol liklik lain dispela i bikpela samting tru — i no gat volium bilong rausim kos bilong wokim dispela proses.

Sekpoint Tu na Tri: Namba Wan Atikol na Ful Inspeksen

Namba wan bod we i no stap long lain em i no tok orait long ran. Fes-atikol inspeksen i sekim ol dimensen, ol solda join, ol komponen refrens na polariti, na konfemim olsem ol ikwipmen na program i stap long stretpela stet pastaim long ol i rilisim kontinu prodaksen. Dispela step i stopim wanpela ful 'batch' long drip, i no gat bikpela pe, na i gutpela tru.

Bihain long dispela, inspeksen i pulap na i no kisim sempel. Olgeta 'solder joints' i save go insait long 'automated optical inspection' (AOI), ol 'hidden joints' olsem BGA i save putim X-rei, na 'flying-probe' na 'functional test' we i gat nid. Ol liklik oda i save tingim prais, na dispela i save pulim ol manmeri long askim sapos ol i ken lusim ol tes — em i narapela kain. Wanpela liklik lain i no gat volium bilong skelim, olsem na wanpela ful inspeksen we i kisim wanpela kol join em i moa isi long wanpela kastoma komplen bihain long sipmen.

Sekpoin Foa: Inspeksen i go aut na pasim wok

Laspela samting em wok bilong putim ol samting long paket na wok bilong sekim ol samting. Bihain long lukluk sekim i kam OQC, konfemim hamas, lebol, rot bilong paketim na wanpela random fanksenel sempel. Long wankain taim, ol i raitim ol hevi we ol i painim long taim bilong 'pilot run': wanem ol 'solder joints' i save kol, we plesmen ofset i save ran bikpela, wanem stesin i tait long takt - na ol dispela konklusen i go bek stret long ol prodaksen paramita. Sapos 'conformal coating', 'full assembly' na 'functional test' olgeta i kamap insait long wanpela plent, orait dispela 'feedback loop' i sotpela; i stap long planti stua, dispela tingting i kamap bihain long ol manmeri i senis.

Plent bilong mipela i save holim 'sampling', liklik 'batch' na 'volume' prodaksen insait long wankain 'plant', wantaim 'pilot' na 'volume' we ol wankain manmeri i save mekim wantaim ol wankain 'parameters'. Wanem samting dispela i baim em i no liklik pe bilong freit, em i wanpela 'unbroken process context' - olgeta samting we i no stret we ol i painim insait long 'pilot' i kamap olsem wanpela samting we ol i save long en long prodaksen lain na i no wanpela ripot we nogat wanpela man i save ritim.

Hau Pilot Run Data i save givim volium prodaksen

Fopela 'checkpoint' insait long wanpela 'pilot run' - namba wan atikol, proses paramita windo, 'yield' long taim nogut tru bilong disain, na 'operator-level failure record' - i save givim gutpela pe tasol sapos ol i karim ol data i go het. Wanpela pailot we i pinis wantaim wanpela pas na i no gat namba i rekodim i no baim klostu wanpela samting. Ol samting we i gutpela long lukautim em 'reflow profile' we ol i yusim, 'solder paste' na 'inspection criteria', 'yield' we i bruk daun long 'failure mode', na lista bilong ol senis long disain we pailot i bin kirapim. Ol dispela 4-pela pepa i kamap olsem rekot bilong namba tu na namba tri oda.

Narapela rot em i dia tumas we i save kamap bihain tasol. Sapos i no gat rekodim profail, namba tu bild we i stap 6-pela mun i no wok bai kamap long memori na i go daun. Sapos i no gat 'failure-mode breakdown', wanpela 'recurring defect' i luk olsem 'bad luck' na i no wanpela 'pattern'. Mipela i save holim ol 'pilot parameters' na 'yield data' wantaim projek, olsem na ol 'repeat orders' i save stat long wanpela 'documented baseline' na i no long 'recollection' bilong opereta.

As tingting bilong wanpela 'Pilot Run' em long feil taim em i no gat bikpela pe

Ol hevi insait long wanpela pailot i save kostim planti taim wanpela droing rivisen na liklik hap bilong wok gen long volium. Taim dispela 'arithmetic' i klia pinis, nogat wanpela man i save askim sapos ol i ken lusim pailot. Askim tru em i 'coverage': namba wan atikol tasol, o wanpela 'continuous run' inap long kamapim 'takt' na givim data.

Ranim 20 i go inap 50 bod. Sotpela ran tumas i no inap long soim ol hevi bilong takt o soim sapos ol feilia i save kamap gen. Wanem samting yu mas lukluk long en long olgeta taim: ol rekot bilong namba wan atikol, ol samting bilong proses olsem 'reflow profile', presa bilong putim na taim bilong 'solder', na as bilong ol samting we i no wok gut. Wantaim dispela tripela, volium prodaksen i save long wanem samting em i mas difendim.

Wanpela pailot i save kamapim ol manmeri na tu ol data. Larim ol volium-lain opereta i holim ol bod long taim bilong pailot em i gutpela moa long namba wan eksposesen bilong ol long de bilong lonsing. Nupela prodak, nupela samting, nupela proses — wanpela bilong ol dispela inap long kamapim hevi, na bringim ol manmeri i go insait long proses hariap em i nambawan insurens we i stap.
