Yog vim li cas tus nqi tooj liab nce ze ze rau EMS Manufacturing nqi

Vim li cas: tooj liab tsis yog cov khoom siv niche - nws yog cov qauv

Tooj liab plays lub luag haujlwm sib txawv los ntawm cov hlau zoo li kub lossis nyiaj. Hauv kev tsim khoom siv hluav taws xob, tooj liab tsis txwv rau ob peb txheej txheem los yog kev ua tiav tshwj xeeb. Nws ua lub hauv paus ntawm:

• Hluav taws xob conduction
• Thermal dissipation
• Mechanical thiab system -theem kev sib txuas

Vim hais tias tooj liab spans cov ntaub ntawv, fabrication, sib dhos, thiab zaum kawg kev koom ua ke, tus nqi hloov propagated thoob plaws lub mov saw nrog me ntsis qeeb.

Kev tshawb fawb kev lag luam nce ntxiv mus rau qhov ntev - lub sij hawm xav tau es tsis yog luv luv - lub sij hawm spike. Kev siv hluav taws xob, AI suav nrog cov cuab yeej siv hluav taws xob, tsheb hluav taws xob, thiab lub zog hluav taws xob txhua tus nyob ntawm ntau qhov tooj liab, thaum cov khoom siv mining tshiab tseem qeeb thiab peev nyiaj ntau. Qhov kev sib xyaw ua ke no ua rau tooj liab volatility ib qho kev rov tshwm sim dua tsis yog kev cuam tshuam ib ntus.

Yuav ua li cas: Tus nqi tooj liab hloov ripple los ntawm EMS tus nqi saw

1) Cov khoom siv khoom siv: tooj liab yog kos rau hauv BOM

Copper raug feem ntau pib ua ntej PCB fabrication:

• Connectors thiab terminals cia siab rau tooj liab alloys raws li cov ntaub ntawv hauv paus
• Inductors, transformers, thiab cov khoom siv fais fab siv tooj liab windings
• Shielding, grounding springs, thiab thermal paths feem ntau koom nrog tooj liab lossis tooj liab alloys
• Cables thiab harnesses sawv cev rau lub cev muaj zog-qib tooj liab siv

Tus kheej, cov khoom no yuav tshwm sim tsawg - nqi. Ua ke, lawv qhia txog qhov tseem ceeb ntawm tus nqi tooj liab - feem ntau cuam tshuam raws li luv luv nqi siv tau, lub sij hawm ua ntej ntev dua, lossis txo cov khoom muaj nyob.

2) PCB manufacturing: qhov twg tooj liab cuam tshuam ncaj qha

Copper -clad laminate (CCL) yog lub hauv paus ntawm PCB fabrication. Nws muab cov khoom siv dielectric nrog tooj liab ntawv ci, ua tus nqi tooj liab thawj zaug thiab ceev tshaj tus nqi kis tau tus mob.

Thaum tus nqi tooj liab nce:

• Copper foil nqi nce
• CCL cov neeg muag khoom kho tus nqi
• Cov lus hais PCB ua raws, feem ntau nrog txo cov sijhawm siv tau

Cov nyhuv no yog amplified nyob rau hauv:

• Multilayer boards
• Cov qauv tooj liab tuab
• Lub zog thiab siab - daim ntawv thov tam sim no

Electroless tooj liab ( txheej txheem PTH): tsis yog - xaiv tau thiab pheej hmoo - rhiab heev.

Electroless tooj liab deposition yog txheej txheem tseem ceeb rau lub qhov metallization thiab conductor tsim. Tsis zoo li nto finishes, nws tsis yog xaiv tau. Tus nqi lossis kev muab khoom tsis ruaj khov ntawm no cuam tshuam tsis yog tus nqi nkaus xwb tab sis kuj tau txais txiaj ntsig zoo sib xws thiab ntev - kev cia siab rau lub sijhawm.

OSP tiav: kev sib txuas ncaj qha rau kev lag luam tooj liab.

OSP tsis yog tooj liab plating. Nws yog cov organic zaj duab xis uas tiv thaiv cov tooj liab los ntawm oxidation. Hauv cov tooj liab siab - nqi ib puag ncig, OSP tej zaum yuav raug txiav txim siab raws li tus nqi - ua kom tiav qhov chaw zoo - tab sis tsuas yog qhov chaw sib dhos qhov rais, cov xwm txheej khaws cia, thiab kev cia siab rau kev tso cai. Nws yog ib qho kev qhuab qhia - qhov kev xaiv tseem ceeb, tsis yog tus nqi luv luv.
