Qhov kev nyab xeeb ntawm hluav taws xob feem ntau yog nyob ntawm theem ntawm lub phaj ua lub Hoobkas, uas feem ntau yog 0.15 hli. Qhov tseeb, nws tuaj yeem nyob ze dua. Yog hais tias lub Circuit Court tsis muaj feem xyuam rau lub teeb liab, tsuav yog tsis muaj luv luv Circuit Court thiab tam sim no txaus, tam sim no loj yuav tsum tau thicker thaiv thiab sib nrug.
1.Qhov deb ntawm cov xov hlau
Qhov kev ncua deb ntawm cov conductors yuav tsum tau txiav txim siab raws li PCB chaw tsim khoom lub peev xwm tsim khoom. Nws raug pom zoo tias qhov kev ncua deb ntawm cov conductors yog tsawg kawg yog 4mil. Txawm li cas los xij, qee qhov chaw tsim khoom kuj tuaj yeem tsim nrog 3/3mil kab dav thiab kab sib nrug. Los ntawm qhov kev xav ntawm ntau lawm, tau kawg, qhov loj dua qhov zoo dua nyob rau hauv tej yam kev mob. Ib txwm 6mil yog cov pa ntau dua.
2.Spacing ntawm ncoo thiab hlau
Qhov kev ncua deb ntawm lub ncoo thiab kab feem ntau tsis tsawg dua 4mil, thiab qhov ntau dua qhov kev ncua deb ntawm lub ncoo thiab kab thaum muaj qhov chaw, qhov zoo dua. Vim hais tias pad welding yuav tsum qhib qhov rais, qhov qhib qhov rais yog ntau tshaj 2mil ntawm ncoo. Yog tias qhov sib txawv tsis txaus, nws yuav tsis tsuas yog ua rau luv luv Circuit Court ntawm kab, tab sis kuj ua rau tooj liab raug ntawm kab.
3.Qhov sib nrug ntawm Pad thiab Pad
Qhov sib nrug ntawm lub ncoo thiab lub ncoo yuav tsum ntau dua 6mil. Nws yog ib qho nyuaj rau ua ib tug solder stop-welding choj nrog tsis txaus pad spacing, thiab IC ncoo ntawm cov tes hauj lwm sib txawv yuav muaj ib tug luv luv Circuit Court thaum vuam qhib weld choj. Qhov kev ncua deb ntawm lub network ncoo thiab lub ncoo yog me me, thiab nws tsis yooj yim rau disassemble cov khoom kho tom qab lub tin yog tag nrho txuas ntawm vuam.
4.Copper thiab tooj liab, hlau, PAD spacing
Qhov kev ncua deb ntawm cov tawv nqaij nyob thiab kab thiab PAD yog qhov loj dua li ntawm lwm cov kab txheej khoom, thiab qhov kev ncua deb ntawm daim tawv nqaij thiab kab thiab PAD yog ntau dua 8mil los pab txhawb kev tsim khoom thiab kev tsim khoom. Vim tias qhov loj ntawm daim tawv nqaij tooj liab tsis tas yuav tsum tau ua ntau tus nqi, me ntsis loj thiab me me tsis muaj teeb meem. Txhawm rau txhim kho cov txiaj ntsig ntawm cov khoom lag luam, qhov sib nrug ntawm txoj kab thiab PAD los ntawm cov tawv nqaij tooj liab yuav tsum loj npaum li qhov ua tau.
5.Spacing ntawm hlau, PAD, tooj liab thiab phaj ntug
Feem ntau, qhov kev ncua deb ntawm cov xov hlau, ncoo thiab tooj liab ntawm daim tawv nqaij thiab cov kab contour yuav tsum ntau dua 10mil, thiab tsawg dua 8mil yuav ua rau tooj liab raug rau ntawm ntug ntawm lub phaj tom qab tsim thiab molding. Yog tias ntug ntawm lub phaj yog V-CUT, qhov sib nrug yuav tsum siab dua 16mil. Hlau thiab PAD tsis yog tsuas yog tooj liab nthuav tawm yooj yim, kab dhau los ze rau ntawm ntug ntawm lub phaj yuav me me, ua rau muaj teeb meem nqa tam sim no, PAD me me cuam tshuam rau vuam, ua rau cov vuam tsis zoo.
