Kev Tshawb Fawb Hais Txog Qhov Ua rau Wrinkling thiab Ua Npuas Ncauj ntawm Circuit Board Soldering Inks

Lub ntsej muag ntawm Circuit Court board nto yog qhov teeb meem tsis zoo ntawm pawg thawj coj saib sab npoo tsev, qhov ntawd yog qhov zoo dua ntawm pawg thawj coj npoo. Qhov no suav nrog ob yam:

1. Cov teeb meem kev nyiam huv ntawm pawg thawj coj;

2. Qhov teeb meem ntawm saum npoo micro-roughness (lossis lub zog saum npoo). Qhov teeb meem ntawm nto blistering rau tag nrho cov Circuit Court board tuaj yeem sau lub ntsiab lus raws li cov laj thawj saum toj no. Cov ntawv cog lus nruab nrab ntawm cov tsho tiv no tsis zoo los yog qis dhau, thiab nws yog qhov nyuaj rau tiv cov plating kev nyuaj siab, kev nyuaj siab lub tshuab, thiab kev nyuaj siab thermal tsim tawm thaum lub sijhawm kev tsim khoom thaum lub sijhawm tom qab cov txheej txheem thiab cov txheej txheem los ua ke, uas thaum kawg ua rau sib txawv ntawm kev sib cais. nruab nrab ntawm plating txheej.

Qee yam ua rau tsis zoo ntawm cov khoom lag luam zoo thaum lub sijhawm txheej txheem ntau lawm yog hais raws li hauv qab no:

1. Cov teeb meem ntawm cov txheej txheem substrate: Tshwj xeeb rau qee cov duab thinner (feem ntau qis dua 0.8 hli), vim tias cov substrates muaj qhov tsis zoo, nws tsis tsim nyog siv lub tshuab txhuam hniav txhawm rau txhuam cov laug cam. Nyob rau hauv txoj kev no, txheej txheej tiv thaiv tshwj xeeb los tiv thaiv oxidation ntawm tooj liab nyob rau saum npoo ntawm cov txheej thaum lub sijhawm ua cov txheej txheem ntawm cov substrate yuav tsis raug tshem tawm zoo. Txawm hais tias txheej yog nyias thiab txhuam phaj yooj yim tshem tawm, nws yog qhov nyuaj rau siv tshuaj kho. Nws yog ib qho tseem ceeb uas tswj cov kev ua, yog li tsis ua rau qhov teeb meem ntawm lub blistering nyob rau saum npoo los ntawm qhov kev sib tsoo tsis zoo ntawm cov ntawv ci tooj liab nyob rau saum npoo ntawm cov xaim thiab cov tooj liab tshuaj lom neeg; qhov teeb meem no tseem tshwm sim thaum cov txheej hauv puab sab hauv yog dub. Kev tsis xws luag, xim tsis ncaj, ib nrab ntawm cov xim browning, thiab lwm yam.

Qhov saum npoo ntawm lub rooj tsav thaum lub sijhawm siv tshuab (drilling, laminating, milling, thiab lwm yam) tshwm sim los ntawm cov roj lossis lwm cov kua ua paug thiab hmoov av tsis zoo ntawm cov nplaim tsis zoo.

3. Txheeb tsis zoo tooj liab txhuam phaj: Ntau dhau ntawm kev sib tsoo ntawm lub hauv ntej sib tsoo lub phaj tooj liab ua rau deformation ntawm orifice, txhuam tawm cov ntawv ci tooj liab ntawm lub orifice, thiab txawm tias xau lub substrate, uas yuav ua rau cov txheej txheem ntawm electroplated tinned soldering Orifice sawv hlwv; txawm hais tias lub pob zeb txhuam tsis ua kom xau tawg ntawm cov xaim hluav taws xob, ib qho dhau ntawm cov txhuam hnyav yuav ua rau muaj qhov txhawm ntawm tooj liab ntawm orifice. Yog li no, cov ntawv ci tooj liab yog yuav tsim ntau dhau los thaum lub sijhawm ua cov txheej txheem micro-etching roughening. Kuj yuav muaj qee yam kev phom sij zoo; yog li ntawd, kev saib xyuas yuav tsum tau them nyiaj rau kev ntxiv dag zog rau kev tswj hwm ntawm txhuam phaj ua tiav. Cov txheej txheem cov txheej txheem ntawm daim phaj txhuam tuaj yeem hloov kho kom zoo rau qhov zoo tshaj plaws los ntawm kev coj khaub ncaws caws pliav thiab kuaj dej zaj duab xis;

4. Cov teeb meem ntxuav: Electroplating tooj liab yuav tsum tau yauv tsum muaj kev siv tshuaj ntau. Ntau hom acids, alkalis, cov kuab tshuaj organic, thiab lwm yam tshuaj muaj ntau cov kuab tshuaj, thiab lub npoo ntawm pawg tswj yuav tsis tau ntxuav nrog dej. Tshwj xeeb, kev hloov kho ntawm cov neeg ua haujlwm rau tooj liab yuav tsis tsuas yog ua rau hla kev sib kis. Nyob rau tib lub sijhawm, nws tseem yuav ua rau thaj chaw hauv thaj chaw tsis zoo los yog cov kev kho mob tsis zoo, qhov tsis sib xws, tsis sib xws, ua rau qee qhov teeb meem hauv lub zog khi; yog li ntawd, peb yuav tsum them sai sai los txhim kho kev tswj kev ntxuav, feem ntau suav nrog kev ntxuav cov dej ntws tawm, dej kom zoo, thiab lub sijhawm ntxuav, Thiab lub sij hawm drip tswj ntawm pawg tswj hwm; tshwj xeeb tshaj yog nyob rau lub caij ntuj no, thaum lub ntsuas kub tsawg, cov nyhuv ntxhua khaub ncaws yuav raug txo kom tsawg, thiab ntau xim yuav tsum them rau kev tswj ntawm kev ntxuav;

5. Micro-etching nyob rau hauv kev kho mob ua ntej tooj liab thiab qauv plating ua ntej kev kho mob: Ntau dhau micro-etching yuav ua rau orifice xau ntawm lub substrate thiab ua kom paug ntawm ib ncig orifice; tsis txaus micro-etching tseem yuav ua kom muaj kev sib txuas ntawm lub zog tsis txaus thiab ua rau sawv hlwv. ; Yog li ntawd, nws yog qhov tsim nyog los ua kom muaj zog ntawm kev tswj hwm ntawm micro-etching; feem ntau, qhov tob ntawm micro-etching ua ntej tooj tso yog 1.5-2 micrometers, thiab micro-etching ntawm cov qauv electroplating yog 0.3--1 micrometers. Nws yog qhov zoo tshaj plaws kom dhau cov tshuaj txheeb xyuas tshuaj thiab cov mob yooj yim. Txoj kev ntsuas kev ntsuas qhov hnyav tswj qhov tuab lossis qhov ntsuas ntawm micro-etching. Feem ntau, txheej npoo ntawm cov phaj tom qab micro-etching yog ci, teeb xim paj yeeb, thiab tsis muaj qhov cuam tshuam txog; yog tias cov xim tsis sib xws, lossis muaj kev xav txog, nws qhia tau tias muaj kev phom sij zoo hauv kev ua haujlwm ua ntej; sau nco Ntxiv kev soj ntsuam; ntxiv rau, cov ntsiab lus tooj liab ntawm lub micro-etching tank, qhov ntsuas kub ntawm cov kua dej da dej, cov nqi thauj khoom, thiab cov ntsiab lus ntawm micro-etching tus neeg sawv cev yog txhua yam khoom siv los them rau;

6. Kev ua haujlwm tsis zoo ntawm cov tooj liab txuas ntxiv: Qee lub rooj ua haujlwm tom qab cov tooj liab lossis cov duab kos ua tiav vim tias lub ntsej muag tsis zoo, cov txheej txheem tsis ua haujlwm lossis cov micro-etching sijhawm tswj thaum lub sijhawm rov ua haujlwm, lossis lwm qhov laj thawj yuav ua rau lub rooj tsavxwm zoo li cov hlwv; Kev ua haujlwm ntawm tooj liab phaj Yog tias tooj liab tau pom tias tsis zoo rau ntawm kab, nws tuaj yeem tshem tawm ncaj qha ntawm kab tom qab ntxuav nrog dej. Pickling tuaj yeem ua tiav yam tsis muaj xeb; Nws yog qhov zoo tshaj plaws kom tsis txhob degrease dua thiab me ntsis corrode. Tam sim no lub micro-etching tank yog fading, them nyiaj rau lub sijhawm tswj, koj tuaj yeem siv ib lossis ob daim hlau los txhawm rau laij lub sijhawm ploj mus kom paub meej cov nyhuv fading; tom qab qhov fading tiav, thov txheej txheej txhuam muag muag thiab tom qab ntawd maj mam txhuam lub rooj tsavxwm thiab tom qab ntawd cov kev tsim cov txheej txheem tooj liab, tab sis lub sijhawm etch yog halved lossis tsim nyog kho tau;
