Lub creator ntawm lub luam Circuit Court board yog lub Austrian Paul Eisler. Nyob rau hauv 1936, nws ua ntej siv ib tug luam Circuit Court board nyob rau hauv xov tooj cua. Nyob rau hauv 1943, Americans siv lub tshuab rau cov tub rog xov tooj cua. Nyob rau hauv 1948, lub tebchaws United States officially paub tus invention coj mus muag siv. Txij li thaum lub nruab nrab-xyoo 1950, luam Circuit Court laug cam tau lug siv.

Ua ntej mus rau lub advent ntawm lub PCB, cov interconnection ntawm cov hluav taws xob Cheebtsam yog ua los ntawm ncaj qha kev twb kev txuas ntawm cov nyob ntawm tej. Niaj hnub no, nyob ntawm tej yog tsuas yog siv nyob rau hauv laboratory daim ntaub ntawv; luam Circuit Court laug cam yog twv yuav raug hu nyob rau hauv ib tug meej kev tswj txoj hauj lwm nyob rau hauv lub electronics kev lag luam.

PCB lawm txheej txheem:

Ua ntej, hu rau lub chaw tsim tshuaj paus thiab ua ib qho kev nug, thiab ces sau npe tus neeg muas zaub tooj, ces ib tug neeg yuav hais ib co lus rau koj, muab ib tug txiav txim, thiab ua raws li cov ntau lawm kev kawm.

Ob, cov ntaub ntawv uas

Hom phiaj: Raws li cov uas yuav tsum tau ntawm engineering cov ntaub ntawv npe nruab nrab, txiav mus rau hauv me me daim ntawm cov loj ntawv los txhim kho lub siv thiab yooj yim.

Txheej txheem: loj daim ntawv cov ntaub ntawv uas → cutboard raws li MI yuav tsum → zom board → ntug sib tsoo → ci board

Peb, xyaum

Hom phiaj: Raws li cov engineering cov ntaub ntawv, yuav tsum tau aperture yog drilled nyob rau coj txoj hauj lwm rau ntawm daim ntawv ntawm qhov yuav tsum tau loj.

Txheej txheem: qaum phaj → laum → qis phaj → soj ntsuam \ kho

Plaub, PTH

Hom phiaj: Tooj txheej tsim los ntawm nws tus kheej-oxidation cov tshuaj tiv thaiv yog kom tiav hluav taws xob interconnection.

Txheej txheem: hangplate → tooj liab sinking automatic kab → qis phaj

Tsib, txheej

Hom phiaj: T ransfer graphics rau lub rooj sib tham tus neeg muas zaub uas yuav tsum tau.

Txheej txheem: (xiav roj txheej txheem): grindboard → sau cov thawj sab → qhuav → sau lub thib ob sab → qhuav → raug → duab ntxoov ntxoo → soj ntsuam; (Qhuav zaj duab xis kev): hemp board → laminate → zaub → cai Ntsis → Raug → Duab ntxoov ntxoo → Check

Sixth, txawv plating

Hom phiaj: Ua lub thickness ntawm tooj liab nyob rau hauv qhov phab ntsa raws li cov zoo yuav tsum thiab xeb resistant txheej plated rau etching.

Txheej txheem: qaum phaj → degreasing → dej ntxuav ob zaug → micro-etching → dej ntxuav → pickling → tooj liab plating → dej ntxuav → pickling → tin plating → dej ntxuav → qis phaj

Xya, zaj duab xis tshem tawm

Hom phiaj: Khiav lub anti-plating txheej txheej nrog NaOH tshuaj rau las qhov uas tsis yog-line tooj liab txheej.

Txheej txheem: ntub zaj duab xis: inserting → soaking alkali → ntxuav → txhuam → dua tshuab; qhuav zaj duab xis: muab board → dua tshuab

Yim, etching

Hom phiaj: Etching yog siv cov tshuaj cov tshuaj tiv thaiv txoj kev mus corrode cov tooj liab txheej nyob rau hauv uas tsis yog-line qhov chaw.

Cuaj, solder daim npog qhov ncauj

Hom phiaj: Ntsuab roj hloov cov qauv ntawm cov ntsuab roj zaj duab xis mus rau lub Rooj Tswjhwm Saib cov los tiv thaiv cov kab thiab tiv thaiv kom txhob tin ntawm txoj kab thaum soldering qhov chaw

Txheej txheem: zom phaj → sau photosensitive ntsuab roj → luam thawj sab → ci daim ntawv → luam lub thib ob sab → ci daim ntawv

Kaum, txhob lo lo ntxhuav kev tshuaj ntsuam

Hom phiaj: Txhob lo lo ntxhuav kev tshuaj ntsuam yog ib qho yooj yim-rau-qhia markup

Txheej txheem: Tom qab qhov kawg ntawm ntsuab roj → txias → kho cov network → sau cim

Kaum ib, kub-plated ntiv tes

Hom phiaj: Plating ib tug txheej ntawm npib tsib xee / kub nrog ib tug yuav tsum tau thickness rau ntawm qhov plug tus ntiv tes kom nws ntau hnav resistant

Txheej txheem: qaum phaj → degreasing → dej ntxuav ob zaug → micro-etching → dej ntxuav ob zaug → pickling → tooj liab plating → dej ntxuav → npib tsib xee plating → dej ntxuav → kub-plated tin phaj (ib tug txheej txheem ntawm juxtaposition)

Kaum Ob tug, ua-free HASL

Hom phiaj: Tshuaj Tsuag tin tsuag nrog ib tug txheej ntawm cov hlau lead tin rau lub liab qab tooj liab nto tsis them nrog solder tawv roj los tiv thaiv cov tooj liab nto los ntawm oxidation thiab oxidation kom zoo soldering kev kawm.

Txheej txheem: micro-etching → cua kom qhuav → preheating → rosin txheej → solder txheej → kub huab cua leveling → cua txias → ntxuav thiab so qhuav

Kaum peb, kawg shaping

Hom phiaj: Los ntawm tus tuag Stamping los yog CNC tshuab txiav tawm tus duab txoj kev txoj kev yuav tsum tau los ntawm tus neeg muas zaub.

Kaum plaub, hluav taws xob kev kuaj

Hom phiaj: Los ntawm lub tshuab hluav taws xob 100% xeem, nws yuav ntes tus qhib Circuit Court, luv luv Circuit Court thiab lwm yam tsis xws luag uas tsis yooj yim pom los ntawm qhov muag pom kev soj.

Txheej txheem: qaum pwm → tso tawm board → xeem → tsim nyog → FQC kev soj ntsuam → unqualified → kho → rov qab xeem → OK → REJ → seem

Kaum tsib, FQC

Hom phiaj: Los ntawm 100% kev soj ntsuam ntawm cov tsos tsis xws luag ntawm lub rooj tsavxwm, thiab kho ntawm me tsis xws luag, kom tsis txhob muaj teeb meem thiab puas board outflow.

Kev ua hauj lwm txaus: cov khoom ntaub ntawv → saib cov ntaub ntawv → kev soj ntsuam → tsim nyog → FQA random tshuaj ntsuam xyuas → tsim nyog → ntim → unqualified → ua → xyuas OK
