10. Cov kev paub txog

Yuav ua li cas laij tus nqi thiab hais ntawm PCB board

Muaj ntau tus neeg yuav khoom PCB feem ntau tau yooj yim los ntawm tas li hloov pauv cov nqi ntawm PCBs. Txawm tias cov neeg yuav khoom uas yuav tsis nkag siab txog cov laj thawj ntawm cov kev hloov pauv no. Ntau yam cuam tshuam rau pcb tus nqi, suav nrog cov ntaub ntawv, kev tsim khoom, cov kev xav tau, cov neeg siv khoom, cov qauv them, cov chaw tsim khoom. Cov xwm txheej no ua rau muaj kev hloov pauv hauv tus nqi PCB Circuit Cots. Hauv qab no, lianxing heeli muab cov lus qhia ntxaws:

1. Qhov cuam tshuam ntawm cov khoom xaiv ntawm PCB nqi

Noj cov khoom siv thib ob ua piv txwv, cov ntaub ntawv feem ntau suav nrog fr -4 {2}}. Board thickness ranges los ntawm 0. 6mm rau 3. {Mm, thaum tooj liab thickness sib txawv los ntawm ½ oz mus rau 3 oz. Cov ntaub ntawv sib txawv tsim cov nqi tseem ceeb. Ib qho ntxiv, cov npog ntsej muag tsis sib haum sib txawv hauv tus nqi, nrog cov roj thermosetting ntau dua li cov roj ntsuab roj. Cov khoom siv cov khoom siv ua rau muaj nqi ntau yam. Kom paub meej ntxiv nyob rau hauv xam pcb nqi, thov saib cov ntawv sau txog.

2. Cov cawv ntawm kev tsim cov txheej txheem ntawm PCB nqi

Cov txheej txheem tsim kev sib txawv ua rau cov nqi sib txawv. Piv txwv li, kub-plated pcbs yog kim dua li cov plated tin-plated. Ib yam li ntawd, cov kev xaiv ntawm milling (kev coj) thiab xuas nrig ntaus rau kev sib tw ntawm pawg txiag cuam tshuam rau cov nqi. Tsis tas li ntawd, kev siv cov kab ntawv lo lo ntxhuav piv rau cov kab zaj duab xis qhuav tuaj yeem cuam tshuam cov nqi tag nrho.

3. Nqe kev hloov pauv vim PCB nyuaj

Txawm tias thaum siv tib cov ntaub ntawv thiab cov txheej txheem, qhov nyuaj ntawm tus PCB tuaj yeem cuam tshuam tus nqi. Piv txwv li, yog tias ob lub pob zeb hluav taws xob txhua tus muaj 1, {1}} qhov muaj qhov sib txawv dua {}}. 6mm, tus nqi drilling yuav sib txawv. Ib yam li ntawd, yog tias txoj kab dav ntawm ib lub rooj tsavxwm yog ntau dua li {}}. 2 hli, cov nqi tsim khoom yuav sib txawv. Ntau qhov nyuaj ua rau muaj cov nqi nce ntxiv, ua rau tus nqi sib txawv.

4. Kev cuam tshuam ntawm cov neeg siv khoom ntawm PCB tus nqi

Cov qhua tuaj noj mov specifications cuam tshuam ncaj qha cuam tshuam cov txiaj ntsig tawm los. Piv txwv li, ib tus kws saib xyuas tsim raws li IPC-{1}}} Cov qauv kev kawm dhau los, thaum tib tus kws saib xyuas 3 tus qauv tsuas yog ncav cuag 90% dhau tus nqi. Qhov qis cov txiaj ntsig nce cov nqi ntau lawm, ua rau tus nqi hloov pauv.

5. Nqe txawv ntawm PCB cov tuam ntxhab

Txawm rau tib cov khoom lag luam, cov chaw tsim khoom sib txawv yuav muaj cov nqi sib txawv vim muaj kev sib txawv hauv cov cuab yeej ua haujlwm, thiab cov txheej txheem tsim khoom lag luam, thiab cov txheej txheem tsim khoom lag luam. Qee cov neeg tsim khoom lag luam xav tau cov khoom lag luam kub-plated PCbs vim cov txheej txheem yooj yim thiab cov nqi seem. Lwm tus tsom rau cov kab mob tin-plated vim tias kev plating kub ntxiv rau cov nqi thaum cov laug cam uas tsis muaj zog raug kaw. Cov kev sib txawv no ua rau cov nqi sib txawv ntawm cov tuam ntxhab.

6. Tus nqi sib txawv vim cov txheej txheem them nyiaj

Lianxing hubi hloov kho PCB nqe raws li cov txheej txheem them sib txawv feem ntau suav nrog 5% mus rau 10%.

7. Cov cheeb tsam sib txawv hauv PCB nqi

Thaj chaw muaj qhov tseem cuam tshuam rau pcb nqe. Feem ntau, PCB tus nqi feem ntau yuav nce ntawm sab qab teb mus rau sab qaum teb. Cov cheeb tsam sib txawv muaj cov nqi ntau lawm, ua rau cov nqi sib txawv.

 

Yuav Ua Li Cas Los Xam Phaj Nqi Pcb

• Cov khoom siv khoom- Tus nqi sib txawv raws hom pcb siv.
• DRILLING TUS NQI- Tus naj npawb ntawm qhov thiab lawv cov diameters tseem cuam tshuam li drilling cov nqi.
• Cov nqi tsim khoom lag luam- Cov txheej txheem sib txawv cuam tshuam cuam tshuam ntau lawm thiab cov nqi.
• Ua haujlwm, cov khoom siv, thiab cov nqi tswj hwm- Cov no vam khom lub Hoobkas tus nqi tswj. Nyob rau hauv dav dav, Taiwan-pab nyiaj txiag zoo li muaj tus nqi qis.

 

Qhov tseem ceeb cuam tshuam rau PCB nqi

1. PCB Cov Khoom Siv

• Fr -4 yog cov khoom txheem txheem rau ob-tog ib sab thiab ntau-txheej PCbs. Nws tus nqi yog nyob ntawm board thickness thiab tooj liab plating thickness.
• Fr -1 Thiab ci -1}}} yog siv rau ib-txheej pheej yig dua ntau-txheej cov laug cam.

2. Board Thickness

• Cov tuab tuab xws li {{{0}}}}}. 8mm, 1.6mm, 1.6mm, thiab 2.0mm. Kev hloov pauv hauv cov tuab me ntsis cuam tshuam cov nqi.

3. Copper thickness

Tooj liab handness cuam tshuam tus nqi, nrog cov kev xaiv sib xws nrog:

• 18μm (½ oz)
• 35μm (1 oz)
• 55μm (1.5 oz)
• 70μm (2 oz)

4. Cov Khoom Siv Khoom Siv Raw Khoom Siv

Cov cuab yeej siv pcb cov ntaub ntawv sib xws suav nrog Shengyi, Jiantao, thiab International, ntawm lwm tus.

Cov nqi tsim khoom lag luam

1. PCB Circuit Court- Yog tias cov kab dav dav yog nyob rau hauv 4/4 Mil, tsub nqi ntxiv yuav thov tau.
2. BGA Cheebtsam- Cov laug cam nrog BGA (pob daim phiaj array) Cheebtsam muaj cov nqi siab dua. Qee tus nqi ua qauv them raws li tus naj npawb ntawm BGA ntawm pawg thawj coj saib.
3. Nto Xov Xwm- Kev kho ntau cov kev sib cuam tshuam cuam tshuam txog kev coj tus nqi. Ua tiav suav nrog:

• Cua Huab Cua Solering Qib (Hasl)
• Wm (organic sngerability preservative)
• Immersion Tin
• Txhaum nyiaj
• Immersion kub
• Txhua txoj kev ua tiav tau muaj tus nqi sib txawv.

Cov Qauv Raug- IPC {-2 yog cov txheej txheem uas yuav tsum tau rau feem ntau cov pej xeem), cov qauv kev lag luam, lossis cov nqi nkag mus tub rog, uas yuav nce cov nqi.

Txij li thaum pcbs yog kev cai tsim, lawv tus nqi yog raws cov kev suav tus nqi. PCB cov tuam ntxhab siv cov khoom siv ua zes ua ntej kom ua rau kev siv tooj liab-clad tus qauv tooj liab.

Qhov nyuaj ntawm PCB them cov kev suav

Lub PCB kev lag luam muaj ib qho ntawm cov qauv muaj nqi tshaj plaws ntawm txhua qhov chaw tsim khoom. Cov kev suav them nqi muaj cov ntaub ntawv txiav, kev lamination, sib sau, tswj zaum kawg (FQC), ntim, thiab ntau dua. Txhua kauj ruam yuav tsum tau siv cov khoom siv, ua haujlwm, thiab kev tsim khoom raug nqi.

Rau cov pcb tshwj xeeb zoo li dig muag / faus vias / cov kab mob kub, thiab cov nqi tooj liab uas siv tau vim yog cov nqi sib xyaw. Ib qho ntxiv, cov ntsiab lus zoo li tho qhov ntau thiab tsawg thaum lub sijhawm khiav dej yuav cuam tshuam cov nqi zaum kawg, ua haujlwm hauv kev kawm tau) thiab kev ntsuam xyuas cov nqi.

Cov lus qhia kawg rau PCB cov neeg yuav khoom

Thaum xaiv cov pcb pcb, cov neeg yuav khoom yuav tsum tsis txhob ua lawv qhov kev txiav txim siab ntawm tus nqi. Hloov chaw, lawv yuav tsum xav txog cov chaw tsim khoom siv lub peev xwm, kev txawj ntse tsim, kev pabcuam zoo, thiab tag nrho cov khoom muaj kev ntseeg tau.
