PCB Rooj Sab Laj Ib Feem Ntau Tshaj Qhov Kev Loj Hlob
Jun 12, 2017

1, Tib Sab Laj Txiav CCL; (yuav tau them cov phom tooj liab, txiav txim siab rau kev txiav cov koob meej, ua ntej txiav txim siab yuav tsum ci nplooj);

2, sib tsoo phaj; (hauv lub zeb hauv kev txiav ntawm CCL tu, yog li cov nplaim tsis muaj plua plav, burrs thiab lwm yam kev sib tsoo, thawj sib tsoo tom qab ci, ob txoj kev yog ib qho);

3, luam tawm Circuit Court; (nyob rau hauv ib sab tooj liab sau rau ntawm daim duab ntawm daim duab, tus number case muaj kev tiv thaiv los ntawm corrosion)

4, Kev Soj Ntsuam Ib Sab Ib Sab; (tus lej feem ntau yuav raug muab tshem tawm, tus cwj mem xaj yuav yog tus cwj mem tsawg dua los sau tus cwj mem, yog pom ntau qhov phem, yuav tsum tau kho, cov khoom tsis zoo yuav raug muab tso rau hauv theem ob hauv qhov ua ntu zauv, ntxuav thiab qhuav rov qab Txoj kev rov ua dua no)

5, number case yuav qhuav;

6, etching; (nrog rau cov reagent yuav tsum muaj tooj liab khib nyiab, nrog rau tus lej ntawm lub voj voog kom tuav cov tooj liab, thiab siv cov lus ceeb toom los ntxuav lub cwj mem ntawm lub voj voog thiab ces ziab, peb cov txheej txheem yog ib qho)

7, Ib Sab Ib Pawg Thaj Tsam Xwb Thaj Chaw; (tom qab etching qhov xyaum qhov chaw tso qhov)

8, sib tsoo ntawv; (lub qhov yuav yog qhov drilling qhov rau tu thiab ziab, thiab 2 substrate)

9, silk screen; (nyob rau sab nraum qab ntawm lub substrate sau rau ntawm lub pob plug-in cov kabmob silk, ib co cim code, silk screen tom qab ziab, ob lub dab yog ib qho)

10, sib tsoo phaj; (thiab ces ib tug huv)

11, kuj tsis ua haujlwm; (nyob rau hauv kev ntxuav ntawm lub substrate tom qab qhov screen printing ntsuab roj solder resist, lub ncoo tsis tau ntsuab roj, luam ncaj qha tom qab ziab, ob lub dab yog ib qho)

12, molding; (nrog punch molding, tsis muaj V VIT kev kho mob yuav muab faib ua ob zaug, xws li cov ntawv me me, pib ntawm lub lo lo ntxhuav ntiv mus rau hauv lub plhaub sab hauv lub hau me me, thiab tom qab ntawd los ntawm cov kab laug sab rau lub ntsej muag liab , thiab lwm yam)

13, V pit; (me me disc tsis muaj kev sib tw ua V, lub tshuab yuav raug txiav tawm ntawm lub rooj tsav khoom nrog ib qho chaw seem)

14, rosin; (thawj sib tsoo lub rooj tsav, ntxuav lub plua av substrate, tom qab ziab, thiab tom qab ntawd coated nrog ib txheej ntawm nyias txheej ntawm rosin, peb cov txheej txheem yog ib qho)

15, Tib Sab Lij Choj kev ntsuam xyuas FQC; (sim seb puas yog lub rhais ntawm lub substrate, qhov, seb qhov twg yog qhov zoo)

16, flattened; (deformation ntawm substrate flattened, lub substrate yog tsis tsim nyog rau tus ua haujlwm ntawm txoj kev no)

17, ntim thiab xa khoom.

Lus Cim: lo lo ntxhuav thiab vuam ntawm kev sib tsoo phaj txheej txheem yuav tsum tau rho, koj tuaj yeem ua ntej, thiab tom qab lo lo ntxhuav, qhov teeb meem tshwj xeeb kom pom cov substrate.

1, luam tawm Circuit Court Ib Sab Laj. Yuav tau kos ib lub rooj tsav xwm zoo uas muaj daim ntawv hloov xa tawm, luam tawm rau ntawm lawv tus kheej, luam tawm ob lub voj voos, uas yog, ib daim ntawv los luam tawm ob lub rooj sib tham. Nyob rau hauv uas xaiv lub zoo tshaj plaws luam tawm Board.

2, txiav CCL, nrog rau kev tsim khoom noj khoom tsim hluav taws xob ntau daim txiag thawm hnub. CCL, uas yog, ob sab yog them nrog lub rooj sib tham nrog tooj liab, lub CCL txiav rau hauv qhov luaj li cas ntawm lub rooj tsav xwm hauv lub rooj sib txoos, tsis dhau loj los khaws cov khoom.

3, ua ntej CCL. Nrog cov nplua nuj nyob rau ntawm cov nplaim tooj ntawm cov roj npoo ntawm cov hlau uas pom zoo los ntawm cov kev hloov ntawm lub rooj tsavxwm, lub thermal hloov daim ntawv rau toner tuaj yeem luam tawm ntawm CCL, tshuam tus txheej txheem ci ntsa iab, tsis muaj kev pom tseeb Stains.

4, hloov khoom siv Xwb Ib Pawg Neeg Sab Nrauv. Yuav luam tawm cov lus pom zoo ntawm lub rooj sib tham kom zoo, luam tawm rau ntawm daim ntawv cog lus ntawm CCL, raws li CC rau hauv lub thermal transfer tshuab, muab tso rau hauv daim ntawv yuav tsum ua kom ntseeg tau tias cov ntawv xa tuaj tsis tawm. Feem ntau, tom qab 2-3 zaug ntawm kev xa mus, lub rooj tsav xwm lub rooj tsavxwm tuaj yeem hloov mus rau CCL.
