Daim ntawv thov
Cia peb qhia qee qhov kev paub txog pcb tooj liab thickness.
Copper foil li pcb conductive lub cev, yooj yim adhesion rau lub rwb thaiv tsev txheej, corrosion daim ntawv Circuit Court qauv.The thickness ntawm tooj liab ntawv ci yog qhia nyob rau hauv oz (oz), 1oz = 1.4mil, thiab qhov nruab nrab thickness ntawm tooj liab ntawv ci yog qhia nyob rau hauv hnyav ib chav tsev. cheeb tsam los ntawm cov mis: 1oz = 28.35g / FT2 (FT2 yog square feet, 1 square feet = 0.09290304㎡).
International pcb tooj liab ntawv ci feem ntau siv thickness: 17.5um, 35um, 50um, 70um.Feem ntau, cov neeg siv khoom tsis ua cov lus tshwj xeeb thaum ua pcb.Cov tooj liab tuab ntawm ib leeg thiab ob sab yog feem ntau 35um, uas yog, 1 amp tooj liab.Tau kawg, qee qhov tshwj xeeb boards yuav siv 3OZ, 4OZ, 5OZ... 8OZ, thiab lwm yam, raws li cov khoom xav tau los xaiv qhov tsim nyog tooj liab tuab.
Qhov dav tooj liab tuab ntawm ib leeg thiab ob sab PCB board yog hais txog 35um, thiab lwm yam tooj liab thickness yog 50um thiab 70um.Qhov saum npoo tooj liab thickness ntawm lub phaj multilayer feem ntau yog 35um, thiab sab hauv tooj liab thickness yog 17.5um.Kev siv Pcb board tooj liab tuab feem ntau yog nyob ntawm kev siv PCB thiab teeb liab voltage, tam sim no loj, 70% ntawm Circuit Court board siv 3535um tooj liab ntawv ci thickness.Tau kawg, rau qhov tam sim no yog lub rooj tsav xwm loj dhau lawm, tooj liab tuab kuj tseem siv tau 70um, 105um, 140um (tsawg heev)
Pcb board siv txawv, kev siv tooj liab thickness kuj txawv.Zoo li cov neeg siv khoom siv thiab kev sib txuas lus, siv 0.5oz, 1oz, 2oz;Rau feem ntau ntawm cov khoom loj tam sim no, xws li cov khoom siv hluav taws xob siab, cov khoom siv hluav taws xob thiab lwm yam khoom, feem ntau siv 3oz lossis siab dua yog cov khoom siv tooj liab tuab.
Lamination txheej txheem ntawm Circuit Court boards feem ntau yog raws li nram no:
1. Kev npaj: Npaj lub tshuab laminating thiab cov ntaub ntawv uas yuav tsum tau (xws li Circuit Court boards thiab tooj liab foils yuav tsum tau laminated, nias daim hlau, thiab lwm yam).
2. Kev kho kom huv: ntxuav thiab deoxidize qhov chaw ntawm lub rooj tsav xwm Circuit Court thiab tooj liab ntawv yuav tsum tau nias kom ntseeg tau zoo soldering thiab kev sib txuas ua haujlwm.
3. Lamination: Laminate cov ntawv ci tooj liab thiab lub rooj tsav xwm hauv Circuit Court raws li qhov yuav tsum tau ua, feem ntau yog ib txheej ntawm Circuit Court board thiab ib txheej ntawm cov ntawv ci tooj liab tau muab tso ua ke, thiab thaum kawg tau txais ntau txheej txheej Circuit Court.
4. Muab tso rau hauv thiab nias: muab lub laminated Circuit Court board rau ntawm lub tshuab pressing, thiab nias lub multi-layer circuit board los ntawm positioning lub pressing phaj.
5. Cov txheej txheem nias: Raws li lub sijhawm thiab lub siab tau txiav txim siab, lub rooj tsav xwm hauv Circuit Court thiab cov ntawv xov tooj tooj liab raug nias ua ke los ntawm lub tshuab nias kom lawv nruj nreem ua ke.
6. Kev kho cua txias: Muab lub rooj tsavxwm nias rau ntawm lub tshuab ua kom txias rau kev kho cua txias, kom nws tuaj yeem ncav cuag qhov kub thiab txias.
7.Kev ua haujlwm tom ntej: Ntxiv cov tshuaj tua kab mob rau saum npoo ntawm lub rooj tsav xwm Circuit Court, ua cov txheej txheem tom ntej xws li drilling, pin insertion, thiab lwm yam., kom ua tiav tag nrho cov txheej txheem tsim khoom ntawm lub rooj tsav xwm Circuit Court.
FAQs
Lub thickness ntawm cov txheej tooj liab siv feem ntau yog nyob ntawm qhov tam sim no uas yuav tsum tau dhau los ntawm PCB.Txheem tooj liab thickness yog kwv yees li 1.4 mus rau 2.8 mils (1 mus rau 2 oz)
Qhov tsawg kawg nkaus PCB tooj liab tuab ntawm tooj liab-clad laminate yuav yog 0.3 oz-0.5oz
Yam tsawg kawg nkaus thickness PCB yog ib lo lus siv los piav qhia tias lub thickness ntawm lub rooj tsavxwm luam tawm yog thinner dua li qub PCB.Tus qauv thickness ntawm lub rooj tsavxwm Circuit Court tam sim no yog 1.5 hli.Qhov tsawg kawg nkaus thickness yog 0.2 hli rau feem ntau ntawm Circuit Court boards.
Qee yam ntawm cov yam ntxwv tseem ceeb suav nrog: hluav taws kub retardant, dielectric tsis tu ncua, qhov tsis zoo, lub zog tensile, shear zog, iav hloov kub, thiab ntau npaum li cas thickness hloov nrog kub (Z-axis expansion coefficient).
Nws yog cov khoom siv rwb thaiv tsev uas khi cov cores uas nyob ib sab, lossis cov tub ntxhais thiab ib txheej, hauv PCB stackup.Lub luag haujlwm tseem ceeb ntawm prepregs yog txhawm rau khi ib qho tseem ceeb rau lwm tus tub ntxhais, khi ib tug tub ntxhais mus rau ib txheej, muab rwb thaiv tsev, thiab tiv thaiv lub rooj tsav xwm ntau yam los ntawm kev luv luv.
