Cov yam ntxwv khoom
1. Cov yam ntxwv zoo hluav taws xob
Kev ua hluav taws xob siab: Kub yog ib tug neeg saib xyuas zoo nrog cov neeg saib xyuas zoo heev uas muaj qhov tsis tshua muaj zog, ua rau muaj kev kis tus kheej, qis} Tsis muaj kev sib kis thiab lub zog. Qhov no yog qhov tseem ceeb rau high- zaus thiab siab} Cov ntaub ntawv ceev hauv cim xeeb thiab cov duab kos duab), txo cov teeb meem duab.
Tsis tshua muaj kev sib cuag: tus du, tawv tawv ua kom muaj qhov chaw ruaj khov tiv thaiv lub qhov muag hluav taws xob lub caij nplooj ntoo hlav tseem ceeb.
2. Cov ntsiab lus tseem ceeb
High corrosion thiab oxidation tsis kam: kub yog lub noble hlau thiab tsis oxidize lossis tarnish hauv huab cua zoo li tooj liab lossis nyiaj. Qhov no tiv thaiv kev tsim ntawm qhov tsis - kev ua yeeb yaj kiab vim tias tsis txaus siab rau cov khoom lag luam tsis zoo thiab ua kom muaj qhov tsis muaj chaw nyob hauv ib puag ncig.
Nto cov Florness thiab Smoonting: Cov kub yog tiaj tus thiab tiv thaiv kev ua kom qis dua ntawm cov poj niam poj niam lub qhov ntswg thaum nqus thiab rho tawm.
3. Lub zog ua cov yam ntxwv
Siab hnav tsis kam: qhov no yog ib qho ntawm cov khoom tseem ceeb tshaj plaws. Nws yog feem ntau ua tiav los ntawm electroplating "nyuaj kub" (kub- libalt lossis kub}} nickel alloy). Cov txheej tawv tawv tawv tuaj yeem tiv thaiv txhiab tus neeg rov qab ua ntau dua thiab cov voj voog extraction tsis muaj kev hnav tseem ceeb, tswj hwm nws cov hluav taws xob.
Mechanical zog: pcb substrate hauv qab cov ntiv tes kub yog feem ntau txhawb nqa cov leeg thaum lub sij hawm nqus dej thiab tshem tawm, tiv thaiv kev tawg lossis deformation.
4. Precision Raug Thiab Qauv
Ua kom nruj ntev ntev: qhov ntev, dav, thickness, spacing, thiab bevel kaum sab nraud) ntawm cov ntiv tes kub yog tswj hwm los ntawm kev tiv thaiv xov tooj cua kub. Cov chamfer saib xyuas cov ntxig yooj yim rau hauv lub qhov muag thiab tiv thaiv kev puas tsuaj rau ob tus ntiv tes thiab cov ntiv tes kub.
PLATING thickness tswj: cov kub thickness yog nruj nreem tswj raws li cov cai thov:
Nyem kub: thicker plating ({0.05 - 0.1 μm), tus nqi qis, siv rau soldering lossis kev thov tsis xav tau mating.
Hard Kub: Thicker plating (feem ntau {{{{{{} μm, txog li 1.27 μm lossis 50 microinchches), siv rau cov txuas rau cov neeg sib txuas.
Qauv Tsim Qauv: Qhov ntev thiab txheej ntawm kub ntiv tes ua raws li rau cov qauv kev lag luam (piv txwv li, ddring interoperability thiab sib cuam tshuam ntawm cov khoom lag luam los ntawm cov khoom lag luam sib txawv.
5. Cov Kab Mob Tshuaj
Tshuaj Kuj: Kub yog resistant rau feem ntau cov acids, alkalis, thiab lwm yam kev siv tshuaj, uas yog qhov ua kom huv si lossis ib puag ncig ib puag ncig yuav tshwm sim.
Cov khoom lag luam zoo
Cov ntsiab lus tseem ceeb ntawm cov kub ntiv tes Circuit Court yog ua raws li kev sib txuas hluav taws xob. Lawv tau dav siv nyob rau hauv cov khoom siv hluav taws xob uas xav tau hloov qauv, hloov chaw, lossis kev nthuav dav. Cov chaw thov tseem ceeb muaj:
Khoos Phib Tawj Ua Vajtse
Qhov no yog cov ntawv thov classic feem ntau. Daim npav nthuav xws li nco cov Modules (RAM), cov duab kos duab (piv txwv li cov ntiv tes
01
Cov Neeg Siv Khoom Electronics
Cov piv txwv nrov tshaj plaws yog video game cartridges (piv txwv li, Nintendo kev ua si console ntawm cov ntiv tes dawb los nyeem cov ntaub ntawv ua si.
02
Khoom Siv thiab Kev Sib Txuas Lus
Hauv cov khoos phis tawj, cov servers, cov rouches, thiab hloov pauv, cov npav nthuav dav, thiab cov npav sib txuas nrog cov ntiv tes kub. Qhov no pab tau kev saib xyuas, hloov kho tshiab, thiab kev hloov kho kom tau raws li kev tswj hwm kev tswj hwm thiab siab- ceev kev sib txuas lus xav tau.
03
Cov teb tshwj xeeb
Hauv Aerospace, cov cuab yeej kho mob (piv txwv li cov cuab yeej kho mob), thiab ntsuas cov khoom siv kub, kom haum rau cov cim kev ncaj ncees hauv cov chaw xav tau.
