Hauv kev siv cov khoom siv hluav taws xob, qhov zoo yog qhov tseem ceeb ntawm kev txiav txim siab qhov ruaj khov thiab lub neej ntawm cov khoom siv. Txoj cai -angle DIP keyboards, vim lawv qhov tshwj xeeb 90℃khoov tus pin qauv thiab siab dependence ntawm spatial layout thiab sib dhos orientation, fim ntau lub peev xwm zoo txaus ntshai thaum lub sij hawm tsim thiab siv.Yog li ntawd, tsim kom muaj ib tug zoo meej tswj system npog tag nrho cov txheej txheem los ntawm raw cov ntaub ntawv kom tau txais cov khoom tiav yog ib qho tseem ceeb rau kev ua tau zoo thiab ruaj khov.
Raw khoom zoo tswj yog thawj kab ntawm kev tiv thaiv. Cov yas yas siv rau lub tsev yuav tsum muaj cov cua kub zoo heev, nplaim taws retardancy, thiab qhov seem stability. Ua ntej nkag mus rau hauv lub Hoobkas, lawv yuav tsum tau mus rau lub melt flow Performance index, kub distortion kub, thiab nplaim retardancy ntsuam xyuas ntsuas los tiv thaiv deformation thiab degradation kev ua tau zoo thaum lub sij hawm siab - kub vuam los yog ntev - siv sij hawm. Cov ntaub ntawv tiv tauj feem ntau yog tooj liab-raws li substrates nrog cov hlau zoo nkauj plating. Lub purity ntawm lub substrate, plating thickness, thiab adhesion yuav tsum tau soj ntsuam, thiab lawv oxidation thiab sulfidation kuj yuav tsum tau soj ntsuam los ntawm kev ntsuam xyuas ntsev tsuag. Cov khoom siv hlau xws li cov khoom siv hluav taws xob, cov txuas txuas hluav taws xob, thiab cov pins yuav tsum tau sim rau qhov hardness, elastic modulus, thiab khoov qaug zog kev ua tau zoo kom ruaj khov txhua yam khoom thoob plaws hauv lawv lub neej. Tus yuam sij rau kev tswj kom zoo hauv kev txhaj tshuaj molding yog nyob rau hauv qhov tseeb thiab sib xws ntawm cov txheej txheem tsis. Pwm kub, txhaj tshuaj siab, tuav lub sij hawm, thiab tus nqi txias yuav tsum tau teem raws li cov khoom siv thiab kaw thiab taug qab los ntawm ib tug tiag tiag - lub sij hawm xyuas system. Moulded qhov chaw raug kuaj pom, tsis lees txais cov cim shrinkage, weld kab, flash, lossis qhov tsis xws luag. Cov qauv tseem raug coj mus rau qhov tseeb qhov tseeb thiab kev ntsuas lub zog ntawm lub zog kom ntseeg tau tias kev sib hloov thiab kev ruaj ntseg ntawm cov qauv thaum sib dhos.
Kev tswj kom zoo hauv cov txheej txheem sib dhos qhia txog kev huv thiab qhov tseeb ntawm qhov chaw. Cov haujlwm ruaj khov ntawm kev sib cuag thiab cov txuas txuas txuas ncaj qha cuam tshuam rau kev ntseeg tau ntawm hluav taws xob txuas ntxiv; Cov khoom siv tshwj xeeb thiab cov cuab yeej tshuaj ntsuam xyuas yuav tsum tau siv los ua kom paub meej txog qhov kev sib raug zoo ntawm qhov chaw. Kev txav mus los ntawm kev txav mus los thiab cov lus tawm tswv yim tactile ntawm cov nyees khawm yuav tsum tau txheeb xyuas ib qho los ntawm ib qho uas siv cov khoom siv kho tshuab kom ntseeg tau tias tsis muaj teeb meem xws li jamming, tsis muaj zog rebound, lossis stroke deviation. Kev huv huv ntawm lub rooj sib txoos ib puag ncig yuav tsum ua kom tau raws li cov qauv tsim los tiv thaiv cov plua plav los ntawm kev ua raws li kev sib cuag ntawm qhov chaw thiab tsim kom tsis txhob muaj qhov cuam tshuam los yog rwb thaiv tsev.
Pin dabtsi yog khoov yog cov txheej txheem tseem ceeb uas txiav txim siab cov yam ntxwv ntawm txoj cai - lub kaum sab xis, thiab nws cov kev tswj kom zoo yog nruj tshwj xeeb. Khoov lub kaum sab xis, tus pin coplanarity, thiab kev ntxhov siab sab hauv ntawm qhov khoov taw tes yuav tsum tau kuaj xyuas siv lub projector lossis kev sib koom tes ntsuas tshuab kom ua raws li cov qauv tsim. Kev saib xyuas tsis tu ncua thiab calibration ntawm dabtsi yog khoov tuag yog qhov tseem ceeb los tiv thaiv batch shape deviations vim tuag hnav. Tom qab khoov, tus pin lub zog ua piv txwv yuav tsum tau tiv thaiv kev ntxhov siab uas tuaj yeem ua rau microcracks lossis tawg.
Kev tswj zoo ntawm cov txheej txheem soldering yog ua raws li tus pin hom. Rau los ntawm - qhov yoj yoj soldering, solder kub, yoj qhov siab, thiab lub sij hawm immersion yuav tsum tau saib xyuas kom tsis txhob kub deformation ntawm lub tsev los yog txias solder pob qij txha. Rau nto mount reflow soldering, kub profiles yuav tsum tau nruj me ntsis tswj kom tsis txhob muaj ntau tshaj solder paste evaporation los yog voids nyob rau hauv lub solder pob qij txha. Tom qab- soldering, optical inspection (AOI) thiab qhov tsim nyog cov khoom siv hluav taws xob txuas ntxiv yuav tsum tau ua kom paub meej txog qhov tsis xws luag tam sim ntawd xws li kev sib txuas, kev sib txuas tsis txaus, lossis kev sib cuag tsis zoo.
Kev ntsuas kev ua haujlwm thiab kev ntseeg siab ntawm cov khoom tiav yog theem kawg ntawm kev tswj kom zoo. Kev ntsuas kev ua tau zoo ntawm cov tshuab suav nrog cov khawm xav tau qhov sib xws, rov ua haujlwm rov ua dua, thiab kev ua haujlwm ruaj khov ntawm tus kheej - kaw lossis tsis yog - tus kheej - kaw haujlwm. Kev ntsuas hluav taws xob kuaj xyuas lub xeev qhib / tawm, tiv thaiv kev tiv thaiv, thiab kev tiv thaiv hluav taws xob ntawm txhua qhov hloov ntawm cov haujlwm sib txawv, kom ntseeg tau tias cov teeb liab tso tawm raws li cov lus qhia tshwj xeeb. Rau cov qauv tsim los rau ib puag ncig hnyav, kev ntsuas kev ntseeg tau xws li kub thiab av noo caij tsheb kauj vab, kev co thiab kev poob siab, thiab ntsev tsuag tshuaj tiv thaiv kuj tseem yuav tsum tau ntsuas qhov ntev - lub sijhawm ruaj khov.
Kev ua tau zoo ntawm cov txheej txheem zoo nyob ntawm cov txheej txheem traceability thiab kev txhim kho txuas ntxiv. Txhua batch ntawm cov khoom yuav tsum tau cim tshwj xeeb, sau cov ntaub ntawv raw khoom batch, ntau lawm cov khoom, txheej txheem tsis, thiab xeem tau. Qhov no tso cai rau kev txheeb xyuas sai ntawm cov laj thawj thiab kho kom raug thaum muaj teeb meem. Kev tshuaj xyuas tsis tu ncua thiab kev txheeb xyuas cov ntaub ntawv pab txheeb xyuas qhov muaj peev xwm thiab cov peev txheej ntawm kev hloov pauv, kev tsav tsheb ua kom zoo dua qub thiab kev tiv thaiv kev tiv thaiv.
Zuag qhia tag nrho, kev tswj kom zoo ntawm txoj cai - lub kaum sab xis DIP keyboards yog ib txoj haujlwm tsim los npog cov ntaub ntawv, molding, sib dhos, sib sau, vuam, thiab kev sim. Tsuas yog los ntawm kev ua raws li kev sim kev tshawb fawb thiab kev tswj xyuas nruj ntawm txhua theem peb tuaj yeem xyuas kom meej tias cov qauv muaj zog, kev ua haujlwm hluav taws xob, thiab kev hloov pauv ib puag ncig ua tau raws li cov qauv, muab cov lus qhia ruaj khov thiab txhim khu kev qha rau cov kev xav tau xws li kev tswj hwm kev lag luam, cov khoom siv sib txuas lus, thiab kev ntsuas.
