Tam sim no, muaj ob hom PCB board ntug tsim: metallization thiab non-metallization. Rau non-metallization, manufacturers nyob rau hauv kev lag luam muaj matured, tab sis lub metallization tshuab tseem tsis paub tab. Niaj hnub no, ntau cov neeg siv khoom xav tau ntau lawm tig mus rau PCB hlau edging . Yog li ntawd, qhov zoo ntawm PCB hlau edging tau dhau los ua qhov tseem ceeb ntawm cov neeg siv khoom thiab cov neeg tsim khoom lag luam vim nws qhov zoo cuam tshuam ncaj qha rau kev siv cov khoom.

 Dab tsi yog daim ntawv thov ntawm ntug plating hauv PCB?

Ntug plating Circuit Court boards muaj nyob rau hauv ntau lub lag luam, thiab ntug plating yog ib qho kev coj ua. Koj yuav pom PCB ntug castellation (lossis ntug plating PCBs) siv rau ntau qhov xwm txheej, suav nrog:

· Txhim kho lub peev xwm nqa tam sim no

· Ntug kev sib txuas thiab kev tiv thaiv

· Ntug soldering los txhim kho fabrication

· Kev txhawb nqa zoo dua rau kev sib txuas xws li cov laug cam uas swb rau hauv cov hlau casings

Dab tsi yog txheej txheem ntawm PCB ntug plating?

Raws li koj paub, muaj ntau yam kev cov nyom rau ib tug multilayer PCB chaw tsim tshuaj paus feem ntau nyob rau hauv yuav ua li cas npaj lub plated npoo thiab lub neej ncua adhesion ntawm cov khoom plated, dab tsi ntxiv, nws xav tau cov precision tuav hauv PCB manufacturing uas yog siv rau ntug. PCB soldering. Peb tuaj yeem ua kom paub tseeb tias PCB ntug castellation tau npaj cov npoo npoo, uas siv cov plated tooj liab kom sai adhesion thiab ua cov txheej txheem Circuit Court kom paub tseeb tias lub sij hawm ntev adhesion ntawm txhua txheej.

Needless hais, peb muaj peev xwm tswj tau lub peev xwm txaus ntshai rau plated los ntawm lub qhov thiab ntug plating nrog cov txheej txheem tswj thaum lub sij hawm luam Circuit Court board manufacturing rau ntug soldering. Yog li qhov kev txhawj xeeb tseem ceeb tshaj plaws yog kev tsim cov burrs, uas ua rau muaj kev cuam tshuam hauv plated los ntawm lub qhov phab ntsa thiab txwv lub neej ntawm adhesion ntawm ntug plating.

Sab nrauv contours, yuav tsum tau metalized, yuav tsum tau milled ua ntej los ntawm-lub qhov plating txheej txheem, raws li cov metallization ntawm cov npoo tshwm sim thaum lub sij hawm fabrication kauj ruam. Tom qab lub deposition ntawm tooj liab, lub npaj nto tiav yog thaum kawg siv rau cov npoo.

Fabrication Issues:

1. Copper Peeling -Plating tshaj ib tug loj substrate nto yuav ua rau lub plated tooj liab tev vim tsis muaj adhesion zog. Peb hais txog qhov no los ntawm kev ua ntej roughening saum npoo los ntawm kev sib xyaw ntawm cov tshuaj thiab lwm yam khoom siv. Tom ntej no, peb siv ncaj qha metallization, uas muaj ntau dua tooj liab daim ntawv cog lus lub zog, los npaj cov nto rau plating.

2. Burrs - Feem ntau ntug plating, tshwj xeeb tshaj yog nyob rau hauv castellation qhov, tuaj yeem ua rau burrs los ntawm cov txheej txheem machining kawg. Peb siv ib qho kev hloov kho, cov txheej txheem tsim khoom ntws uas ua rau cov burrs raug polished mus rau ntawm ntug ntawm qhov tshwj xeeb.

Fab Note:

1. Lub kav hlau txais xov txoj hauj lwm ntawm lub ncoo kub yog loj heev, cuam tshuam rau cov neeg siv khoom soldering lossis teeb liab kis tau tus mob.

2. Lub puab ntug ncoo txuas nrog cov xov hlau ntawm lub rooj tsavxwm, uas ua rau muaj kev cuam tshuam luv luv.

3. Lub stamp qhov yog tsim los ntawm edging groove thiab yuav tsum tau ua nyob rau hauv 2nd drilling txheej txheem.

4. Los ntawm cov txheej txheem ntsig txog kev tsim khoom ntawm tus kheej PCBs raws li lub vaj huam sib luag, kev sib txuas txuas ntxiv ntawm cov npoo sab nrauv tsis tuaj yeem ua tau. Tsis muaj metallization tuaj yeem siv rau qhov chaw me me txuas hniav nyob.

5. Ib qho kev thov, cov zawv zawg plating metallization tuaj yeem npog nrog daim npog ntsej muag.

Thaum muas ntug plating boards, koj yuav tsum paub meej nrog koj tus neeg muag khoom PCB qhov ua tau ntawm kev tsim cov PCBs nrog cov txheej txheem plating, thiab qhov twg tus fabricator tuaj yeem ntug phaj ntawm PCB. Koj cov ntaub ntawv Gerber lossis fab kos duab yuav tsum qhia nyob rau hauv ib txheej txheej txheej uas lawv xav tau swb plating, thiab nto tiav lawv xav tau ntawm nws. Feem ntau cov neeg tsim khoom nyiam xaiv ENIG raws li qhov tsuas yog nto tiav haum rau puag ncig castellation.
