Raws li lub hauv paus tseem ceeb hauv cov khoom siv hluav taws xob siv rau kev teeb tsa kev teeb tsa thiab kev hloov pauv, kev ua haujlwm ruaj khov thiab kev ua neej nyob ntawm cov swb swb feem ntau nyob ntawm cov khoom siv tseem ceeb. Los ntawm cov khoom siv rau cov khoom siv hluav taws xob, kev xaiv ntawm txhua yam khoom siv yuav tsum xav txog txhua yam muaj zog, cov yam ntxwv ntawm hluav taws xob, kev tiv thaiv ib puag ncig, thiab kev ua tau zoo kom ua tau raws li qhov kev ua tau zoo thiab kev ntseeg tau ntawm cov kev thov sib txawv.
Cov vaj tse thiab lub hauv paus yog cov txheej txheem yooj yim ntawm cov keyboards swb, feem ntau yog ua los ntawm engineering plastics los ntawm kev txhaj tshuaj molding. Cov ntaub ntawv muaj xws li siab-kub resistant polycarbonate (PC), nplaim taws-retardant acrylonitrile-butadiene-styrene copolymer (ABS), thiab iav fiber reinforced nylon (PA66+GF). Cov ntaub ntawv no muaj cov rwb thaiv tsev zoo heev, qhov ruaj khov, thiab lub zog txhua yam, tuaj yeem tiv taus qhov kub thiab txias thaum lub sij hawm reflow soldering los yog yoj soldering txheej txheem, thiab tswj cov qauv kev ncaj ncees nyob rau hauv cov av noo, plua plav, thiab tej yam tshuaj lom neeg ib puag ncig. Nplaim taws-kev hloov kho retardant ua rau lawv muaj kev nyab xeeb siab, txo qhov kev pheej hmoo ntawm hluav taws los ntawm cua kub txawv txav.
Txoj kev zawv zawg thiab qhov kev txhawb nqa substrate ntawm cov kev sib txuas ruaj khov kuj yog ua los ntawm cov lus hais saum toj no engineering plastics. Lawv qhov chaw tiav thiab hnav tsis kam tau raug kho kom zoo kom ntseeg tau tias du, qis - kev sib txhuam ntawm cov slider thaum lub sij hawm reciprocating motion, txo qhov muaj feem cuam tshuam ntawm cov khoom hnav ntawm kev sib cuag. Hauv qee cov khoom lag luam uas yuav tsum muaj kev ua haujlwm siab, qhov chaw taug qab tau txais cov txheej txheem tshwj xeeb los txhim kho hnav thiab tiv thaiv corrosion.
Cov khoom siv hluav taws xob yog lub hauv paus tseem ceeb ntawm kev hloov hluav taws xob ua haujlwm, feem ntau suav nrog cov kev sib txuas ruaj khov, txav cov neeg sib cuag, thiab cov phiaj xwm hluav taws xob ntawm lub slider. Lub substrate feem ntau yog ua los ntawm high -purity electrolytic tooj liab los yog phosphor bronze vim nws zoo conductivity thiab nruab nrab elasticity. Txhawm rau txo kev tiv thaiv kev tiv thaiv thiab txhim kho oxidation thiab sulfidation tsis kam, qhov saum npoo feem ntau yog coated nrog cov hlau zoo nkauj plating, xws li kub, nyiaj, lossis kub -silver alloy. Kub plating muaj tshuaj lom neeg ruaj khov heev, tiv thaiv oxidation thiab sulfidation tshwm sim thaum lub sij hawm ntev - siv, kom ntseeg tau cov teeb liab ntshiab; silver plating muab zoo hnav tsis kam thiab arc tsis kam thaum tuav conductivity. Lub plating thickness thiab adhesion yuav tsum nruj me ntsis tswj kom tsis txhob nthuav tawm lub hauv paus hlau vim hnav los yog thermal stress, uas yuav cuam tshuam rau kev ua tau zoo.
Lub caij nplooj ntoos hlav thiab rov pib dua txheej txheem feem ntau yog ua los ntawm stainless hlau lossis piano hlau. Cov yav tas muaj zoo corrosion kuj, thaum lub tom kawg boasts ib tug siab elastic txwv thiab ntev qaug zog lub neej. Tom qab kev kho cua sov kom tsim nyog thiab kev ua haujlwm ntawm qhov chaw, lawv muaj zog rov qab ruaj khov thaum lub sijhawm ua haujlwm zawv zawg, ua kom ntseeg tau cov lus qhia tactile thaum hloov cov iav thiab txhim khu kev qha.
Cov pins tau categorized rau hauv - qhov thiab qhov chaw -mount hom raws li lawv ntim. Los ntawm - qhov pins feem ntau siv tooj dag lossis phosphor bronze strips, tin-plated los yog kub-plated los txhim kho solderability thiab oxidation kuj. Nto-mount pins feem ntau siv siab-cov khoom siv tooj liab, precision stamped thiab khoov; coplanarity thiab qhov tseeb qhov tseeb ntawm cov pins ncaj qha cuam tshuam rau qhov zoo ntawm soldering thiab kev ruaj ntseg ntawm kev sib txuas hluav taws xob.
Nyob rau hauv ib puag ncig tshwj xeeb, xws li - kub, corrosive heev, los yog siab - vibration tej yam kev mob, swb DIP keyboards kuj yuav siv tau hloov siab - kub resistant plastics (xws li PEI, PPS) los yog hlau vaj tse rau encapsulation, nrog thickened hu plating los yog multi- txheej txheej los txhim kho ib puag ncig ntxiv. tsis kam.
Feem ntau, cov ntaub ntawv tseem ceeb ntawm tus swb DIP hloov muaj xws li siab -kev ua tau zoo engineering plastics, ua tau zoo tooj liab substrate nrog cov hlau zoo nkauj plating, corrosion-resistant caij nplooj ntoos hlav steel, thiab alloy ua nrog zoo heev solderability. Qhov kev sib xyaw ua ke ntawm cov ntaub ntawv thiab precision machining tsim ib lub hauv paus txhim khu kev qha rau kev hloov ntawm cov tshuab, hluav taws xob, thiab kev ua haujlwm ib puag ncig, ua rau nws ua haujlwm ruaj khov rau lub sijhawm ntev hauv kev tswj hwm kev lag luam, kev sib txuas lus, kev ntsuas, thiab cov neeg siv khoom siv hluav taws xob, ntsib ntau yam kev xav tau engineering.
