1, npaj rau kev tsim khoom ntawm Circuit Court
Ua ntej pib kev tsim khoom ntawm txheej txheej txheej txheej, lub shenzhenPrint Circuit Coffic Board HoobkasYuav tsum tau ua kev soj ntsuam nruj me ntsis thiab ua ntej - Kev kho mob ntawm cov tub ntxhais cov tub ntxhais ua kom tiav txheej txheej. Firstly, qhov loj me, thiab kev ncaj ncees ntawm lub voj voog sab hauv ntawm cov tub ntxhais lub zog lossis visually tshuaj xyuas kom ntseeg tau tias tsis muaj lub hauv paus rau kev nce qib ntawm cov txheej txheem tom ntej. Nyob rau tib lub sijhawm, impurities, oxides, thiab lwm yam nyob rau saum npoo ntawm cov tub ntxhais lub tub ntxhais lub tub ntxhais yuav tsum tau muab tshem tawm. Micro etching kev kho mob feem ntau yog siv rau roughen lub tooj hluav taws xob tooj liab los ntawm kev txhim kho tooj liab txheej, tso rau hauv lub hauv paus rau kev tsim cov txheej txheem txheej txheem.
2, zaj duab xis thov thiab kis tus txheej txheem
(1) Zaj duab xis sticking txheej txheem
Tom qab ua tiav npaj ua ntej npaj, cov ntawv luam tawm cov board Hoobkas hauv Shenzhen yuav nruj nreem ua kom lub ntsej muag qhuav photoresist rau saum npoo ntawm cov tub ntxhais pawg tub ntxhais. Cov txheej txheem no yuav tsum tau kho kom haum xws li ntsuas kub, thiab ceev kom paub meej tias cov yeeb yaj kiab qhuav thiab dawb huv ntawm cov tub ntxhais thiab tawv tawv. Piv txwv li, zaj duab xis kub yog feem ntau tswj hwm ntawm 100-110 Degree C, lub siab yog tswj hwm ntawm ib ncig ntawm 1.5-2 feeb raws li cov yeeb yaj kiab qhuav thiab qhov xwm txheej tiag tiag ntawm cov kab ntau lawm. Los ntawm cov txheej txheem tswj no tswj hwm, cov yeeb yaj kiab qhuav tuaj yeem tiv thaiv cov chaw ntawm cov tub ntxhais tub ntxhais cov txheej txheem zoo rau kev ua kom tiav.
(2) kab mob kis
Tom qab zaj yeeb yaj kiab yog thov, nws tam sim ntawd nkag mus rau theem kis. Lub tuam txhab SHENZHENT CARDCATHER HEEV {{1} - ionistant txheej nrog cov qauv Circuitor. Cov ntsiab lus tseem ceeb thaum lub sijhawm raug hluav taws xob muaj xws li lub zog siv hluav taws xob thiab lub sijhawm ua tib zoo, uas yuav tsum tau ua tib zoo kho raws li hom yeeb yaj kiab qhuav thiab Circuit Court. Feem ntau hais lus, lub zog raug hluav taws xob yog tswj hwm ntawm 80-120MJ / cm ², thiab raug hloov pauv ntawm cov khoom hluav taws xob thiab cov khoom hluav taws xob rau cov khoom siv hluav taws xob.
(3) tsim cov txheej txheem
Daim Ntawv Qhia Txog Cov Thawj Coj Caum Txom Nyem kom tshem tawm cov yeeb yaj kiab qhuav tsis tau muaj hluav taws xob uas yuav tsum tau ua electroplated lossis etched. Shenzhen luam tawm cov tuam txhab cov lus pov thawj feem ntau siv cov kws tsim tawm alkaline kom yaj thiab yaug tawm cov yeeb yaj kiab uas tsis pom cov cua txias ntawm cov kub thiab tshuaj tsuag. Qhov kub ntawm tus tsim tawm feem ntau tswj hwm ntawm 30-35℃c, cov tshuaj tsuag / cm ², thiab lub sijhawm kev txhim kho tau hloov kho ntawm 60-90 vib nas this raws li qhov xwm txheej tiag tiag. Thaum lub sijhawm cov txheej txheem no, cov ntawv luam tawm Circuit Coffic Board Hoobkas hauv Shenzhen yuav ua rau pom kev loj hlob thiab tsis meej thiab kev ntseeg tau ntawm cov txheej txheem sab nraud.
3, electroplating thiab etching cov txheej txheem
(1) cov txheej txheem electroplating
Tom qab kev loj hlob, cov ntawv luam tawm cov board nkag mus rau cov txheej txheem electroplating, uas yog ib kauj ruam tseem ceeb hauv kev txhim kho qhov kev coj ua thiab tuab ntawm sab nraud Circuitity. Lub tuam txhab Shenzhen luam tawm cov board Hoobkas siv cov txheej txheem tooj liab los tso rau hauv cov tawv tooj liab thiab tuab cov tooj liab ntawm cov tooj liab loj los ntawm electrolysis. Nyob rau tib lub sijhawm, ib txheej nyias nyias ntawm tin txhuas alloy lossis ntshiab}- ay resist resist- resist - resist-} resist-} resist-} resist-} resist --}}-} resist-} ay Cov tsis muaj yeej xws li ceev ceev, plating daws teeb meem, thiab plating daws teeb meem thaum lub sij hawm hluav taws xob hluav taws xob yuav tsum tau tswj hwm preceplating. Piv txwv li, qhov ceev ceev tam sim no feem ntau yog feem ntau ntawm 1.5-3A / thiab lub sijhawm electroplating nyob ntawm qhov yuav tsum tooj liab txheej tuab, feem ntau nyob ib puag ncig 30-60 feeb. Los ntawm cov qauv ntsuas hluav taws xob ntsuas hluav taws xob, nws yog qhov ua tau kom ntseeg tau tias cov txheej txheem sab nraud muaj cov kev ua tau zoo thiab cov khoom siv hluav taws xob nyuaj uas yuav tsum muaj cov khoom hluav taws xob.
(2) etching txheej txheem
Tom qab electroplating tiav, ntau dhau ntawm tooj liab ntawv ci yog muab tshem tawm siv etching txheej txheem los ua cov qauv sib tw kawg. Cov kev daws teeb meem feem ntau siv cov tshuaj shenzhen luam tawm yog tsis muaj kev tiv thaiv los ntawm Tin Leaded los ntawm Tin Ua Alloy lossis ntshiab Tin los ntawm cov tshuaj lom neeg. Qhov kub thiab txias, contrate ntawm etching daws, thiab etching lub sij hawm thaum lub sij hawm etching muaj qhov cuam tshuam tseem ceeb rau kev etching nyhuv. Qhov etching kub yog feem ntau tswj hwm ntawm 45-55℃c, thiab surch℃ntawm cov kev daws teeb meem etching yog tswj hwm nyob rau qee qhov ntau. Lub sijhawm etching raug hloov kho raws li qhov tseeb ntawm Circuit Court thiab cov tuab ntawm tooj liab ntawv ci, feem ntau ntawm 60-120 vib nas this. Thaum lub sij hawm etching, luam tawm cov boardcuital board hauv shenzhen zoo saib xyuas tias cov npoo ntawm lub corrcuit Court ntawv ci, yog li ua kom zoo nkauj tooj liab ntawv thiab ua kom zoo nkauj thiab qhov tseeb ntawm lub txheej txheem sab hauv.
4, Zaj duab xis tshem tawm thiab txheej txheem kev kho mob
(1) zaj duab xis tshem tawm cov txheej txheem
Tom qab etching tiav lawm, nws yog ib qho tsim nyog los tshem tawm cov txhuas txhuas alloy lossis ntshiab} {}}}} ua cov yeeb yaj kiab uas tseem tshuav. Lub Tuam Txhab Shenzhen BROGRATECT BOANCULS Kev Kho Mob Tshuaj Lom Zem, feem ntau yog siv zaj duab xis tshem tawm kom yaj tau qhov ntsuas kub thiab txias thiab kub thiab ntxuav thiab ntxuav lawv kom huv si. Qhov kub thaum lub sijhawm ua yeeb yaj kiab kev tshem tawm feem ntau tswj hwm ntawm 40-50 feeb raws li cov yeeb yaj kiab uas tsis tsim nyog tau muab tshem tawm, thaum zam kev puas tsuaj rau cov txheej txheem tsim.
(2) cov txheej txheem kev kho kom zoo
Txhawm rau txhim kho lub solderability, oxidation tsis kam, thiab coj kev tawm tsam ntawm cov ntawv luam tawm hluav taws xob yuav ua cov tshuaj tiv thaiv saum npoo av ntawm cov txheej txheem sab nraud. Cov txheej txheem kho kev kho kub xws li cov huab cua kub lev, organic soldability tiv thaiv los ntawm cov cua kub txheej, txhim kho lub solderability ntawm lub voj voog; Cov tshuaj lom neeg npib kub cuam tshuam nrog cov txheej txheej ntawm lub nroog tsibckelus alloy ntawm cov khoom siv hluav taws xob tsis kam lees cov khoom siv hluav taws xob nrog kev ntseeg tau.
