Txoj hauv kev ntsuas V tau siv ntau xyoo hauv kev tsim khoom luam tawm hauv Circuit Court board (PCB). Nrog PCB kev tsim khoom thev naus laus zis hloov pauv sai, nws yog ib qho tseem ceeb kom paub txog cov txheej txheem ntsuas PCB tshiab kawg kom ua raws thiab lawv yuav txawv li cas ntawm qhov koj tau siv ua ntej.

The scoring process involves two blades that rotate closely together point-to-point as the PCB moves between the blades. Cov txheej txheem yuav luag zoo ib yam li txiav pizza rau hauv pancake, txiav cov pizza rau hauv nyias nyias thiab tom qab ntawd txav cov khoom mus rau theem tom ntej, uas tuaj yeem txhim kho kev tsim khoom tag nrho. Yog li thaum twg koj yuav tsum siv ntsuas ntawm koj li PCB? What are the potential drawbacks of this process?

Square luam tawm Circuit Board

Txawm hais tias koj lub PCB yog plaub fab lossis duab plaub, txhua sab muaj kab ncaj thiab tuaj yeem txiav ntawm lub tshuab V-notch. Cov lus nug nug yog, nws puas tsim nyog rau kev muab qhab nia, lossis puas muaj lwm qhov chaw uas yuav tsum tau hais? Kom tau qhab nia lossis tsis tau qhab nia? Here are a few reasons for refusing to answer.

Cov qhab nias thinner PCBS

Luam tawm cov phiajcim hauv vaj huam sib luag nyias nyias ntau dua 0.040 ntiv yog qhov nyuaj rau thawb rau ntau qhov laj thawj. Yam tsawg kawg ntawm 0.012 “yuav tsum tau ua kom ruaj khov V-shaped coil, raws li cov khoom siv (kauj) cov ntawv thais sab laug tau teeb tsa ib txhij thais 0.010”- qhov tob ntawm 0.012 “ntawm ob sab yuav ua rau 0.020″ +/- 0.004 ” net me dua 0.040 “.

Thinner printed circuit boards have some deflection only in the material. Saj zawg zog PCBS siv txoj hauv kev tawg ua rau qis yuav ua rau cov npoo ntxhib thiab dai cov fibers. Tswj cov txheej txheem ntsuas nrog cov ntaub ntawv nyias thiab tso cai cuam tshuam tseem ceeb yog qhov nyuaj dua. Cov hniav yog qhov tseem ceeb rau kev ua siab ntev ntawm qhov tob ntawm qhov nqis siab tshaj los ntawm sab saum toj mus rau hauv qab, thiab muaj qhov sib zog ua kom raug kom ntseeg tau tias cov khoom siv dav tsis tawg thaum sib dhos. Thaum qhov tob ntawm qhov thais tsis sib luag ntawm sab laug thiab sab xis, ib feem yuav nyuaj dua kom tawg, tawm hauv cov fibers thiab tuaj yeem ua rau tawg ntawm ntug.

Cov PCB hauv qhov array tau qhab nia

Kev sau ntau dua yog siv, qhov tsis muaj zog ntawm cov vaj huam sib luag tuaj yeem dhau los, ua rau kev tswj hwm tsis zoo, cov pawg puas thiab/lossis teeb meem sib dhos.

Parts with smaller ratings

The smaller the square inch of the board, the harder it is to disconnect. Thaum PCB loj me me, cov laug cam tuab dua 0.062 “nyuaj dua cais. Tsawg dua 1 nti nyob rau hauv ib qho kev taw qhia yuav xav tau cov cuab yeej ntxiv los cais cov ntu.

Score the PCB which is too long

Luam tawm cov laug cam nrog ntev X lossis Y (12 ntiv tes lossis ntau dua) yuav ua rau tsis muaj zog thiab tawg tau yooj yim yog tias lawv khawb tob heev. Ntxiv cov khoom hnyav rau qhov twb tsis muaj zog tuaj yeem ua rau cov panels tawg thaum tuav, sib dhos, lossis tseem thauj mus los. Kev ua tiav cov qhab nia dhia lossis cov kev qhia tab yuav yog qhov kev xaiv zoo dua.

Phaj phaj

Yog tias koj tab tom muab qhab nia PCBS ntau dua 0.096 ntiv tes tuab, siv tib lub tswv yim, nrog ob lub ntsej muag txiav tob dua rau hauv daim iav, tawm hauv net 0.020 ntiv tes +/- 0.004 ntiv tes. Saum toj no cov tuab, nws nyuaj rau tawg, vim khoov tsis txaus. Cov tuab tuab tuaj yeem siv txoj hauv kev no rau cov laug cam tuab, tab sis qee zaum nws tuaj yeem ua rau muaj teeb meem nrog tooj liab mus rau ntug kev sib nrug.

Cov cuab yeej ntsuas

Muaj cov cuab yeej muaj los pab txiav txim siab PCBS. Txawm li cas los xij, nws yuav tsum tau siv kom raug thiab saib xyuas kom raug kom tiv thaiv ntug kev puas tsuaj, tawg lossis khawb saum npoo av. Kev tuav tes ntxiv ntawm kev sib sau ua ke PCBS ib txwm muaj kev pheej hmoo.

Add an Angle or radius to the part

Qhov no puas cuam tshuam rau lub peev xwm los siv txoj kev ntsuas?

Tsis yog, tab sis koj tseem xav tau cov tiaj tiaj kom khawb lub rooj tsavxwm. Feem ntau, thaum siv txoj hauv kev thais, PCBS yuav sib koom ua ke. Lub tshuab txiav txiav ob sab saum toj thiab hauv qab.

Txhawm rau cuam tshuam nrog cov ces kaum lossis kab rov tav, koj yuav tsum tso qhov chaw nruab nrab ntawm PCBS. Ib tus kws tshaj lij Router npaj siv 0.096 “milling cutter uas xav tau tsawg kawg 0.100” txhawm rau txhuam huv ntawm ib feem. Kuj tseem muaj qhov pov tseg tsawg kawg ntawm ib feem. Nws tsis pom zoo kom siv 0.100 “kev sib nrug thiab thais txheej txheem ntawm cov laug cam, txawm tias muaj cov cuab yeej, nws nyuaj heev los ua txhaum. Thaum xav tau chaw, nws raug nquahu kom siv 0.200 “lossis qhov sib nrug ntau dua rau cov nicks.

PCB tsim cov cai rau cov tsim qauv

Teb cov lus nug ib txwm; Yog, koj tuaj yeem qib yuav luag txhua daim ntawv luam tawm lub rooj tsavxwm nrog ntug ncaj, tab sis koj yuav tsum tau siv qhov sib tw ua kom tau qhab nia thiab txuas xov.

Cov khoom kub kub laminated nrog siab dua 150TG muaj cov khoom sib xws thiab cov qauv me me. Do not use the standard fraction parameters used in the 130tg material standard. Kev sib faib ua ntu zus xav tau txhawm rau txhawm rau rhuav cov ntaub ntawv muaj zog no yooj yim dua. Rau cov khoom kub dua, siv 0.015 “+/- 0.004” mesh.

Los ntawm ntug hlau, txheej tiv thaiv yuav tsum raug kho kom tuab ntawm daim ntawv luam tawm Circuit Board. Thaum sib npaug los yog tsawg dua 0.062 “, qhov nrug nruab nrab ntawm cov hlau thiab qhov tseeb ntawm phaj yuav tsum yog yam tsawg 0.015”. Nov yog tus lej siv zoo. Cov tuab tuab tuaj yeem siv 0.096 “lossis 0.125” nce thiab 0.020 “lossis siab dua yog tias qhov chaw tso cai rau txhua txoj haujlwm los ntawm ntug ntawm daim npav.

Rau cov ntawv xov xwm hluav taws xob luam tawm tsawg dua 0.040 “hauv tuab, ib txwm npaj tsuas yog siv cov hlua rau thaiv kom tsis txhob muaj teeb meem.
