Qee cov ntsiab lus tseem ceeb kom nco ntsoov thaum tsim qauv PCB pawg thawj coj saib:

I. Cov lus piav qhia ntxaws ntxaws txog kev tsim PCB tsim

1. The line

(1) Tsawg kawg kab dav: 6mil (0.153mm). Ntawd yog hais, yog kab dav tsawg dua 6mil, nws yuav tsis tuaj yeem tsim khoom. Yog tias kev tsim qauv tso cai, qhov loj dua tsim, zoo dua kab dav dav, zoo dua hauv kev tsim khoom hauv tsev, ua kom tau txiaj ntsig ntau dua. Cov rooj sib tham tsim qauv dav dav nyob ib puag ncig 10mil, lub ntsiab lus no tseem ceeb heev, yuav tsum tau txiav txim siab hauv kev tsim qauv.

(2) Tsawg kab kab nrug: 6mil (0.153mm). Yam tsawg kawg kab nrug deb, uas yog, kab rau kab, kab rau ncoo nrug tsis pub tsawg dua 6mil los ntawm cov khoom lag luam pom, qhov loj dua qhov zoo dua, qhov dav dav hauv 10mil, tau kawg, cov qauv tsim, qhov loj dua qhov zoo dua qhov no taw tes yog qhov tseem ceeb heev, yuav tsum tau txiav txim siab hauv kev tsim.

(3) Nrug deb ntawm kab rau kab contour 0.508mm (20mil)

2. Ntawm qhov (feem ntau paub tias yog qhov ua haujlwm)

(1) Yam tsawg kawg aperture: 0.3mm (12mil)

(2) Qhov tsawg kawg los ntawm qhov (VIA) qhov siab yuav tsum tsis pub tsawg dua 0.3mm (12mil), ncoo ib sab yuav tsum tsis pub tsawg dua 6mil (0.153mm), tshwj xeeb tshaj yog ntau dua 8mil (0.2mm) tsis txwv (saib daim duab 3) ) lub ntsiab lus no tseem ceeb heev, yuav tsum tau txiav txim siab hauv kev tsim qauv

(3) los ntawm qhov (VIA) qhov rau qhov sib nrug (qhov sab rau sab sab) yuav tsum tsis pub tsawg dua: 6mil zoo dua 8mil lub ntsiab lus no tseem ceeb heev, yuav tsum tau txiav txim siab hauv qhov tsim

(4) Distance between pad and contour line 0.508mm(20mil)

(5) a. Hole to line spacing:

NPTH(without welding ring) : hole compensation 0.15mm back distance line more than 0.2mm

PTH (nrog lub nplhaib txuas): qhov them nyiaj 0.15mm thiab siab dua kab nrug 0.3mm

B. Hole-to-hole spacing:

PTH (nrog lub nplhaib txuas): 0.15mm tom qab them nyiaj rau 0.45mm lossis ntau dua

NPTH hole: 0.15mm to 0.2mm after hole compensation

VIA: The spacing can be slightly smaller

3. PAD PAD (commonly known as plug hole (PTH))

(1) Qhov loj ntawm lub qhov ntsaws yog nyob ntawm koj cov khoom siv, tab sis nws yuav tsum loj dua koj tus pin txuas. Nws tau pom zoo tias tus pin txuas loj dua tsawg kawg 0.2 hli, uas yog hais tias, 0.6 ntawm tus pin tivthaiv, koj yuav tsum tsim nws li 0.8 yam tsawg kawg, txhawm rau tiv thaiv kev ua haujlwm tsis txaus ntseeg los ntawm kev nkag yooj yim.

(2) Plug qhov (PTH) lub nplhaib sab nraud ib sab yuav tsum tsis pub tsawg dua 0.2 hli (8mil), tau kawg, qhov loj dua qhov zoo dua (raws li qhia hauv daim duab 2) qhov no yog qhov tseem ceeb heev, tsim qauv yuav tsum tau txiav txim siab

(3) Plug qhov (PTH) qhov rau qhov sib nrug (qhov ntug rau lub qhov ntug) yuav tsum tsis pub tsawg dua: 0.3mm ntawm chav kawm, qhov loj dua qhov zoo dua (raws li cim hauv daim duab 3) Qhov no yog qhov tseem ceeb heev, yuav tsum txiav txim siab hauv qhov tsim

(4) Distance between pad and contour line 0.508mm(20mil)

4. Vuam

(1) Plug-in qhov qhib qhov rai, SMD qhov qhib qhov sab yuav tsum tsis pub tsawg dua 0.1 hli (4mil)

5. Cov Cim (kev tsim cov cim ncaj qha cuam tshuam rau kev tsim khoom, thiab qhov meej ntawm cov cim muaj feem cuam tshuam nrog kev tsim cov cim)

(1) lub ntsiab lus dav dav yuav tsum tsis pub tsawg dua 0.153mm (6mil), lo lus siab yuav tsum tsis pub tsawg dua 0.811mm (32mil), qhov dav piv rau qhov siab sib piv ntawm qhov kev sib raug zoo tshaj yog 5 uas yog hais, lo lus dav 0.2 hli lo lus siab yog 1 hli, txhawm rau thawb chav kawm

6. The minimum spacing of non-metallic grooves should not be less than 1.6mm, otherwise it will greatly increase the difficulty of edge milling (Figure 4)

7. Kev Ua Si

(1) collage nrog lossis tsis muaj qhov sib txawv collage, thiab nrog qhov sib txawv collage, cov duab sib dhos sib txawv nrog qhov sib txawv yuav tsum tsis pub tsawg dua 1.6 hli (tuab ntawm 1.6) mm, txwv tsis pub nws yuav ua rau nyuaj heev ntawm milling ntug collage ua haujlwm phaj loj tsis yog zoo ib yam nyob ntawm cov cuab yeej sib txawv, qhov sib txawv ntawm qhov tsis muaj qhov sib txawv collage txog 0.5mm txheej txheem ntug tsis tuaj yeem tsawg dua 5mm

Ii. Cov teeb meem muaj feem xav tau kev saib xyuas

1. Daim ntawv tseem ceeb ntawm PADS tsim.

(1) PADS tau tso rau hauv hom tooj liab, thiab peb lub tuam txhab tso tooj liab hauv Hatch hom. Tom qab cov ntaub ntawv tseem ceeb ntawm cov neeg siv khoom raug txav mus, lawv yuav tsum tau rov muab tooj liab los khaws cia (Dej nyab tso tooj liab) kom tsis txhob luv luv.

(2) Lub ntsej muag lub ntsej muag hauv ob lub vaj huam sib luag PADS yuav tsum tau teeb tsa mus rau, tsis yog ParTIal. Drilling cov ntaub ntawv tsis tuaj yeem tsim tawm, ua rau qhov xau xau.

(3) Tsis txhob ntxiv cov qauv tsim hauv PADS ua ke nrog cov khoom siv, vim tias GERBER tsis tuaj yeem tsim ib txwm muaj. Txhawm rau kom tsis txhob muaj qhov xau, thov ntxiv cov zawj hauv DrillDrawing.

2. Cov ntaub ntawv hais txog PROTEL99SE thiab DXP tsim

(1) Our company’s Solder mask layer is subject to Solder mask layer. If the Paste layer needs to be made, and the Solder window with multiple layers cannot generate GERBER, please move to the Solder layer.

(2) Tsis txhob xauv txoj kab contour hauv Protel99SE. GERBER tsis tuaj yeem tsim tawm ib txwm muaj.

(3) Hauv DXP cov ntaub ntawv, tsis txhob xaiv KEEPOUT kev xaiv, nws yuav tshuaj xyuas kab ntawv sib dhos thiab lwm yam khoom, tsis tuaj yeem tsim GERBER.

(4) Thov xyuam xim rau qhov tsim thiab qhov tsis zoo ntawm ob hom ntaub ntawv no. Hauv txoj ntsiab cai, txheej txheej saum toj kawg nkaus yog qhov zoo, thiab txheej hauv qab yuav tsum tau tsim los ua thim rov qab. Peb lub tuam txhab ua cov phaj los ntawm kev teeb tsa los ntawm saum toj mus rau hauv qab. Ib phaj tshwj xeeb saib xyuas, tsis txhob tsom iav ntawm qhov yuav! Tej zaum nws yog lwm txoj kev ncig

3. Lwm yam kev ceev faj.

(1) Cov duab (xws li phaj phaj, qhov, V-txiav) yuav tsum tau muab tso rau hauv KEEPOUT txheej lossis txheej txheej txheej, tsis tuaj yeem muab tso rau lwm txheej, xws li txheej txheej luam ntawv, txheej txheej. All slots or holes that need mechanical molding should be placed in one layer as far as possible to avoid leakage.

(2) yog tias txheej txheej txheej thiab KEEPOUT txheej ob txheej ntawm qhov tsos tsis sib xws, thov ua cov lus qhia tshwj xeeb, ntxiv rau cov duab kom ua tau zoo, xws li muaj lub puab sab hauv, thiab sab hauv zawj sib tshuam phaj phaj sab nrauv ntawm txoj kab ntu yuav tsum tau muab tshem tawm, tsis muaj qhov khoob hauv lub puab tsaig sab hauv, tsim hauv txheej txheej txheej thiab KEEPOUT txheej zawj thiab qhov feem ntau yog ua los ntawm tooj liab qhov (ua zaj duab xis txhawm rau khawb tooj liab), Yog tias nws yuav tsum tau ua tiav rau hauv cov hlau, thov ua cov lus tshwj xeeb.

(3) If you want to do the metalized slot the most safe way is to put together a plurality of pad, this approach must not go wrong

(4) Thov ceeb toom tshwj xeeb seb nws puas tsim nyog ua lub bevel ua thaum tso qhov kev txiav txim ntawm phaj ntiv tes kub.

(5) Thov txheeb xyuas seb puas muaj txheej tsawg dua hauv GERBER cov ntaub ntawv. Feem ntau, peb lub tuam txhab yuav tsim ncaj qha raws li GERBER cov ntaub ntawv.

(6) Use three kinds of software design, please pay special attention to whether the key position needs to expose copper.
