Ol gutpela samting bilong semikondakta na elektroniks ikwipmen: 'vacuum', 'cleanliness' na 'outgassing'

Stori

Jun 15, 2010

Insait long 'atmosphere' ol i save skelim wanpela rum long sais, 'flatness' na 'sealing-face roughness'. Insait long wanpela 'vacuum system' ol samting i save senis olgeta: 'outgassing rate', 'surface adsorption', 'residue' insait long ol 'blind hole', na 'galvanic risk' we ol narapela metal i tatsim. Nogat wanpela bilong en i stap long droing.

Ol i save skelim wanpela hap insait long 'vacuum' long narapela kain rot

Insait long win ol i save skelim wanpela 'aluminum chamber' long sais, 'flatness' na 'sealing-face roughness'. Insait long wanpela 'vacuum system' i gat narapela kain set: 'material outgassing rate', 'surface adsorption', 'residue' we i pas insait long ol 'blind hole', na 'galvanic corrosion' we ol narapela metal i bung. I no gat wanpela bilong ol dispela i kamap long droing, na wantaim ol i save makim sapos 'chamber' i save pam i go daun long mak.

Outgassing i save kamap long wara na ol samting i stap antap long graun, na tu, haidrojen i stap insait long dispela samting. Anodising i save mekim 'surface area' i kamap planti na tanim 'oxide' i kamap olsem wanpela 'sponge'; kolsan i pas insait long wanpela hul i no inap kamap i save lusim inap planti aua. Long ol 'precision components' we ol i wokim long ol 'semiconductor' ikwipmen, namba wan samting ol i mas mekim em i no 'accuracy' tasol ol i mas klin na ol i ken save long en.

Outgassing: Tritmen bilong pes i bikpela samting moa long aloi

Long wankain 6061 aluminium, ol samting we i no gat samting long en, ol i bin polisim long marasin na ol i bin putim hatpela 'anodise' long en i gat narapela narapela 'outgassing rate' long wanpela oda bilong mak. Anodising em i no inap bagarap na bagarap, tasol aninit long bikpela 'vacuum' em i save wok olsem wanpela spons. Long ol samting we i bikpela samting long rausim ges, kemikel o elektrolaitik polising na tu, kukim aut long bikpela hat em i gutpela bekim.

Pes bilong pasim em i narapela samting we ol i save lusim. Vacuum sealing i dipen long wanpela O-ring o wanpela metal seal, na raf na klinpela bilong dispela pes i save makim 'leak rate' stret. Smoother em i no gutpela hariap: sapos yu polisim planti tumas dispela i save rausim strong bilong holim gris na i save kamapim ol skrais taim yu bungim. Sensible band em i save stap olsem Ra 0.4 i go inap 0.8, na i no gat ol makmak na i no gat ol liklik hap samting i stap insait long en.

Ol i save bosim klinpela pasin long namba wan taim ol i katim

Klinpela i no kamap long laspela wasim; em i stap gut stat long namba wan operesen. Ol samting bilong salfa na klorin insait long kolsan i save go insait long liklik hul bilong aluminium na bihain em i hat long rausim. Oil long ol samting, das long ol 'conveyor' na 'plastisaiser' long ol 'packaging' olgeta i save kamap olsem ol samting we i save bagarapim ol samting long pinis bilong en.

Ol stua we i wokim ol 'semiconductor' o 'electronics' straksa i nidim wanpela 'cleaning line' - 'ultrasonic', 'DI rinse', 'dry' - wantaim wok bilong sekim wara resistiviti na namba bilong ol liklik hap samting. Taim yu wok long sekim wanpela saplaia em i gutpela long lukluk long dispela lain: sapos ol hap bilong en i wankain olsem ol narapela wok, klinpela i no inap kamap. Em i wanpela samting we i save pasim rot bilong wokim ol 'sheet metal' na ol 'stamping parts' i go insait long wanpela 'semiconductor supply chain'.

Pinis bilong pes: Tripela Rot, Tripela Hevi

Ol samting bilong elektronik i save gat wanpela bilong tripela pinis: 'anodising', 'chemical conversion coating' olsem 'conductive chromate', o 'painting'. Anodising i save pasim na i no inap long bagarap tasol i save groim hap long tripela i go inap long 8-pela maikron long wanwan pes, olsem na ol hul i gat tret i mas karamapim. Konvesen koting i save karimaut na i no save senisim ol sais, we i stret long ol 'grounding points'. Pent em i no gat bikpela pe tasol em i save lusim ges aninit long 'vacuum' o hat.

Wanem wanpela i aplaim i dipen long wok bilong en. Wanpela pes we i mas graun i no inap long kisim 'anodise'; wanpela pes we i mas pasim san na sakim bagarap i no inap long dipen long 'conversion coating' tasol; olgeta samting klostu long 'optics' i mas abrusim peint, we ol 'volatiles' bilong en bai pas long lens. Raitim dispela insait long ol droing not em i no gat bikpela pe tumas winim wok gen bihain.

Tolerans na Asembli: Ol i wokim stretpela pasin bilong freim, ol i no wokim long masin

Long ol hap bilong freim bilong ol semikondakta ikwipmen, singel-pis tolerans i no save hatwok tumas; asua we i bungim long taim bilong bungim em. Wanpela tu-mita freim we ol i wokim long planti 'extrusions' na 'plates', we olgeta wan wan i holim long 'plus' o 'minus' 0.1mm, inap long bungim tupela milimita ausait. Ansa em i no long taitim olgeta hap i go long 0.02mm, we i save mekim kos i go antap, tasol long yusim ol wankain fiting na stretim ol 'shims'.

Dispela i min olsem disain bilong riviu bilong wokim ol samting i mas separetim ol 'assembly dimensions' na ol 'function dimensions'. Ol 'assembly dimensions' inap long kisim ol rong we i kamap long rot bilong ol 'adjuster'; ol wok dimensen, olsem wanpela 'rail mounting face', ol i mas holim stret. Sapos yu makim tupela klas long droing em i klia sain bilong wanpela droing we i gat gutpela straksa.

Pakejing na Transpot: Ol klinpela hap i no wok gut taim ol i opim

Klinpela samting inap long kamap 99 pesen na i no wok gut yet long 'packaging'. Pasin bilong bagarap long ol hap bilong ol semikondakta ikwipmen em taim ol i opim: hap i klin, tasol beg i lusim 'plasticiser', das bilong 'desiccant' i ranawe, o wanpela pepa i stap namel long tupela beg na i putim olgeta samting i go antap taim ol i opim.

Wanpela stretpela spesifikasen bilong 'packaging' i karamapim 4-pela samting. Insait bilong en em i wanpela 'cleanroom-grade' dabol beg na i no wanpela nomol PE film. Ol i save rausim 'nitrogen' o 'vacuum' long beg bilong daunim 'adsorption'. Ol i save pasim 'desiccant' wanwan na bai das i no ken ranawe. Ausait bokis i yusim pepa bilong klinim rum o 'bubble wrap' na i no yusim 'corrugated board' we i stap stret wantaim dispela hap. Long ol hap we i save kisim autgas, ol i mas rausim ol silikon rilis ejen na oiled anti-rust pepa tu.

Trenspot tu i nidim menesmen. Tempereja na humiditi i senis insait long wanpela kontena bilong solwara i save kamapim kondensesen insait long paket; ol mak bilong wara i save kamap long ain, na aninit long 'vacuum' ol dispela mak i save kamap olsem ol 'adsorption site'. Ol longpela sipmen i mekim na ol i mas putim ol 'humidity indicator cards' na wanpela kontrak inspeksen windo bihain long ol i kamap, long wanem, ol hevi we ol i painim ausait long dispela windo i hat long tok.

Wanpela laspela poin we i isi long lusim: 'packaging' em i hap bilong 'traceability'. Beg i mas karim 'cleaning batch' na deit bilong en, sapos nogat, wanpela 'particle excursion' i go long kastoma i no inap kamap long taim bilong klinim o long trenspot.

Hau long sekim wanpela semikondakta ikwipmen saplaia

Tripela filta. Namba wan, ol ikwipmen: 'five-axis' inap, inap long holim ol hap we i winim tupela mita, na CMM inspeksen. Namba tu, proses: wanpela lain bilong klinim, wanpela 'anodising' o 'conversion-coating' patna, na ol narapela ripot bilong 'outgassing' o 'cleanlines' we i gat nid. Namba tri, sistem: ISO 9001 olsem plua, RoHS na CE bilong salim ol samting long Yurop, UL i dipen long kastoma — long wanpela OEM bilong ol ikwipmen laspela samting em kastoma bilong ol yet i save putim na i no ol yet, olsem na em i gutpela long askim pastaim.

I no gat planti saplaia i save winim tripela wantaim, na i no gat nid long stat long dispela. Stat wantaim ol straksa we i no bikpela samting, stretim gut wok bilong klinim na putim ol samting long paket, na bihain putim ol bikpela hap. Long wanpela baia, gutpela volium saplai - ol bikpela oda we i kamap long taim stret - i save winim wanpela gutpela hap bilong wanpela taim tasol. Wanpela man bilong wokim ol ikwipmen we i wok long wanpela ODM model i nidim dispela pepa pastaim long wanpela OEM, bikos dispela tul i gat nem bilong kastoma bilong em; na wanpela 'wholesale distributor' we i no inap long tok klia long wok bilong klinim ol hap bilong en i salim ol bokis na i no ol komponen.
