PCB yog dab tsi?
PCB hais txog Printed Circuit Board, uas yog cov khoom siv hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob thiab cov tseem ceeb ntawm txhua yam khoom siv hluav taws xob. PCB is also known as PWB (Printed Wire Board).
Dab tsi ntawm cov ntaub ntawv PCB tuaj yeem txiav nrog laser cutters?
Hom PCB cov ntaub ntawv uas tuaj yeem txiav los ntawm kev txiav laser txiav muaj xws li hlau-raws li cov ntawv luam tawm Circuit Court boards, ntawv-raws li cov ntawv luam tawm Circuit boards, epoxy iav fiber ntau luam ntawv Circuit Court boards, composite substrate printed circuit boards, tshwj xeeb substrate printed circuit boards thiab lwm yam substrate. cov ntaub ntawv.
Ntawv PCBs
Hom ntawv luam tawm Circuit Board no yog ua los ntawm cov ntawv fiber ntau ua cov khoom siv ntxiv, tsau rau hauv cov tshuaj resin (phenolic resin, epoxy resin) thiab qhuav, tom qab ntawd coated nrog cov nplaum-coated electrolytic tooj liab ntawv ci, thiab nias rau hauv qhov kub thiab txias. . Raws li American ASTM / NEMA cov qauv, cov hom tseem ceeb yog FR-1, FR-2, FR-3 (cov saum toj no yog cov nplaim hluav taws kub XPC, XXXPC (cov saum toj no tsis yog nplaim hluav taws). scale ntau lawm yog FR-1 thiab XPC luam ntawv Circuit Court boards.
Fiberglass PCBs
Hom ntawv luam tawm Circuit Board no siv epoxy lossis hloov kho epoxy resin ua cov khoom siv ntawm cov nplaum, thiab cov ntaub iav fiber ntau ua cov khoom siv ntxiv. Tam sim no nws yog lub tuam txhab luam ntawv loj tshaj plaws nyob hauv lub ntiaj teb thiab feem ntau siv hom ntawv luam tawm Circuit Board. Hauv ASTM / NEMA tus qauv, muaj plaub tus qauv ntawm epoxy fiberglass daim ntaub: G10 (tsis yog nplaim hluav taws), FR-4 ( nplaim taws retardant). G11 ( khaws cia lub zog kub, tsis nplaim hluav taws xob), FR-5 ( khaws cia lub zog kub, nplaim hluav taws retardant). Qhov tseeb, cov khoom uas tsis yog nplaim hluav taws poob qis ib xyoos ib zaug, thiab FR-4 suav rau feem coob.
Composite PCBs
Hom ntawv luam tawm Circuit Board no yog ua los ntawm kev siv cov khoom siv sib txawv los tsim cov khoom siv hauv paus thiab cov khoom siv tseem ceeb. Cov tooj liab clad laminate substrates siv feem ntau yog CEM series, ntawm cov CEM-1 thiab CEM-3 yog cov neeg sawv cev tshaj plaws. CEM-1 puag ntaub yog iav fiber ntau daim ntaub, cov khoom tseem ceeb yog ntawv, cob yog epoxy, nplaim retardant. CEM-3 puag ntaub yog iav fiber ntau daim ntaub, cov khoom tseem ceeb yog iav fiber ntau ntawv, cob yog epoxy, nplaim retardant. Cov yam ntxwv tseem ceeb ntawm cov khoom siv hluav taws xob sib txuas yog sib npaug rau FR-4, tab sis tus nqi qis dua, thiab kev ua haujlwm zoo dua li FR-4.
Hlau PCBs
Hlau substrates (aluminium puag, tooj liab puag, hlau puag lossis Invar steel) tuaj yeem ua rau ib leeg, ob npaug, ntau txheej hlau luam tawm Circuit Board lossis hlau core luam tawm Circuit Board raws li lawv cov yam ntxwv thiab kev siv.
PCB siv rau dab tsi?
PCB (lub rooj tsavxwm luam tawm) yog siv rau hauv cov khoom siv hluav taws xob, khoom siv hauv tsev, khoom siv kho mob, khoom siv hluav taws xob, khoom siv kev nyab xeeb & kev nyab xeeb, cov khoom siv sib txuas lus, LEDs, cov khoom siv tsheb, kev siv dej hiav txwv, cov khoom siv dav hlau, kev tiv thaiv & kev siv tub rog, thiab lwm yam. daim ntawv thov. Hauv cov ntawv thov uas yuav tsum muaj kev nyab xeeb siab, PCBs yuav tsum ua tau raws li cov qauv zoo, yog li peb yuav tsum ua txhua yam ntawm cov txheej txheem tsim khoom PCB tiag tiag.
Lub laser cutter ua haujlwm li cas ntawm PCBs?
Ua ntej tshaj plaws, txiav PCB nrog laser sib txawv ntawm kev txiav nrog cov tshuab xws li milling lossis stamping. Laser txiav yuav tsis tawm hauv cov plua plav ntawm PCB, yog li nws yuav tsis cuam tshuam rau kev siv tom qab, thiab kev ntxhov siab thiab thermal kev nyuab siab qhia los ntawm laser rau cov khoom yog negligible, thiab cov txheej txheem txiav yog maj mam maj mam.
Tsis tas li ntawd, tshuab laser tuaj yeem ua tau raws li qhov yuav tsum tau ua kom huv. Cov neeg tuaj yeem tsim PCB nrog kev ua kom huv thiab zoo los ntawm STYLECNC lub laser txiav tshuab los kho cov khoom siv hauv paus tsis muaj carbonization thiab discoloration. Tsis tas li ntawd, txhawm rau tiv thaiv kev ua tsis tiav hauv cov txheej txheem txiav, STYLECNC kuj tau tsim cov qauv tsim hauv nws cov khoom los tiv thaiv lawv. Yog li ntawd, cov neeg siv tuaj yeem tau txais txiaj ntsig zoo heev hauv kev tsim khoom.
Qhov tseeb, tsuas yog los ntawm kev kho qhov tsis zoo, ib tus tuaj yeem siv tib lub laser txiav cov cuab yeej los ua ntau yam ntaub ntawv, xws li cov ntawv thov txheej txheem (xws li FR4 lossis ceramics), insulated hlau substrates (IMS) thiab system-in-packages (SIP). Qhov kev hloov pauv no ua rau PCBs tuaj yeem siv rau hauv ntau yam xwm txheej, xws li cua txias lossis cua sov ntawm cov cav, chassis sensors.
Hauv kev tsim ntawm PCB, tsis muaj kev txwv ntawm cov qauv, vojvoog, daim ntawv lo lossis lwm yam. Los ntawm kev txiav tag nrho lub voj voog, PCB tuaj yeem muab tso ncaj qha rau ntawm lub rooj, uas ua rau muaj txiaj ntsig zoo ntawm kev siv qhov chaw. Txiav PCBs nrog lub laser txuag ntau dua 30% cov khoom piv rau cov txheej txheem txiav tshuab. Qhov no tsis tsuas yog pab txo tus nqi ntawm kev tsim cov PCBs tshwj xeeb, tab sis kuj tseem pab tsim kom muaj ib puag ncig zoo phooj ywg.
STYLECNC lub laser txiav tshuab tuaj yeem yooj yim ua ke nrog Cov Txheej Txheem Kev Ua Haujlwm (MES) uas twb muaj lawm. Lub tshuab laser qib siab ua kom muaj kev ruaj ntseg ntawm cov txheej txheem ua haujlwm, thaum lub tshuab tsis siv neeg lub cev kuj ua rau cov txheej txheem ua haujlwm yooj yim. Ua tsaug rau lub zog siab dua ntawm cov khoom siv laser sib xyaw, cov tshuab laser niaj hnub no muaj kev sib piv rau cov tshuab tshuab hauv cov ntsiab lus ntawm kev txiav ceev.
Tsis tas li ntawd, cov nqi khiav lag luam ntawm lub tshuab laser yog tsawg vim tsis muaj qhov hnav xws li milling taub hau. Tus nqi ntawm cov khoom hloov pauv thiab lub sijhawm poob qis tuaj yeem zam tau.
Dab tsi ntawm laser cutters siv rau PCB ua?
Muaj peb hom PCB laser cutters ntau tshaj plaws hauv ntiaj teb. Koj tuaj yeem xaiv txoj cai raws li koj qhov kev xav tau ntawm PCB fabrication.
CO2 Laser Cutters rau kev cai PCB Prototype
Lub tshuab CO2 laser txiav yog siv los txiav PCBs ua los ntawm cov ntaub ntawv tsis yog hlau, xws li ntawv, fiberglass, thiab qee cov ntaub ntawv sib xyaw. CO2 laser PCB cutters raug nqi los ntawm $3,000 txog $12,000 raws li qhov sib txawv.
Fiber Laser Tej Tshuab rau Custom PCB Prototype
Fiber laser cutter yog siv los txiav PCBs ua los ntawm cov ntaub ntawv hlau, xws li txhuas, tooj liab, hlau, thiab Invar steel.
