I. Nkọwa zuru oke nke ihe nrụpụta imebe PCB metụtara

1. The line

(1) Obere ahịrị ahịrị: 6mil (0.153mm). Nke ahụ bụ, ọ bụrụ na obosara ahịrị erughị 6mil, ọ gaghị enwe ike ịmịpụta. Ọ bụrụ na ọnọdụ imewe kwere, ka imewe ka ukwuu, ka mma ahịrị ahịrị, ka mmepụta ụlọ nrụpụta ka mma, ka mkpụrụ ya dị elu. Mgbakọ nhazi izugbe dị ihe dịka 10mil, isi ihe a dị ezigbo mkpa, a ga -atụlerịrị ya na nhazi ahụ.

(2) oghere kacha nta: 6mil (0.153mm). Ogologo kacha dị n’ahịrị, ya bụ, ahịrị n’ahịrị, ahịrị ruo n’ahịrị pad adịghị ihe na -erughị 6mil site na nlele mmepụta, nke ka nke ka mma, izugbe n’ozuzu na 10mil, n’ezie, ọnọdụ imewe, nke ka nke ka mma isi dị ezigbo mkpa, a ga -atụlerịrị ya na nhazi ahụ.

(3) site na oghere (VIA) oghere ruo oghere oghere (oghere n’akụkụ ruo oghere n’akụkụ) ekwesịghị ịbụ ihe na -erughị: 6mil ka mma karịa 8mil ebe a dị ezigbo mkpa, a ga -atụlerịrị ya na nhazi ahụ.

(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 (ya na mgbanaka ịgbado ọkụ): nkwụghachi oghere 0.15mm na karịa ahịrị anya 0.3mm

B. Hole-to-hole spacing:

PTH (ya na mgbanaka welded): 0.15mm mgbe akwụchara oghere ruo 0.45mm ma ọ bụ karịa

Oghere NPTH: 0.15mm ruo 0.2mm mgbe akwụchara oghere

VIA: Ogologo ya nwere ike pere mpe

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

(1) Nha nke oghere plọg dabere na akụrụngwa gị, mana ọ ga -eburịrịrịrị karịa ntụtụ akụrụngwa gị. A na -atụ aro ka ntụtụ plọg buru ibu karịa opekata mpe 0.2mm, ya bụ, 0.6 nke pin akụrụngwa, ị kwesịrị ịhazi ya ka ọ bụrụ opekata mpe 0.8, iji gbochie ntachi obi nke igwe na -ebute site na ntinye siri ike.

(2) Oghere nkwụnye (PTH) mgbanaka dị n’otu akụkụ ekwesịghị ịbụ ihe na -erughị 0.2mm (8mil), n’ezie, nke ka mma (dị ka egosiri na eserese 2) isi a dị ezigbo mkpa, a ga -atụle atụmatụ.

(3) Oghere nkwụnye (PTH) oghere ka oghere oghere (oghere ruo n’ọnụ ọnụ) ekwesịghị ịbụ ihe na -erughị: 0.3mm n’ezie, nke ka nke ka mma (dịka akara na FIG.3) Isi a dị ezigbo mkpa, ga -abụrịrị atụle na imewe

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

4. ịgbado ọkụ

(1) Mepee windo oghere oghere, akụkụ oghere windo SMD ekwesịghị ịbụ ihe na-erughị 0.1mm (4mil)

5. Njirimara (imewe nke mkpụrụedemede na -emetụta mmepụta ozugbo, yana idoanya nke mkpụrụedemede nwere njikọ na imewe mkpụrụedemede)

(1) obosara okwu mkpụrụedemede enweghị ike ịbụ ihe na -erughị 0.153mm (6mil), ịdị elu okwu ahụ nwere ike erughị 0.811mm (32mil), oke obosara na ịdị elu nke mmekọrịta kacha mma bụ 5 nke ahụ bụ, okwu obosara okwu 0.2mm n’obosara bụ 1mm, iji mee ka klaasị nwee ike

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. Ihe mgbagwoju anya

(1) mkpokọta nwere ma ọ bụ na -enweghị kọlọji oghere, yana kwa oghere oghere, oghere mkpokọta na oghere ekwesịghị ịbụ ihe na -erughị 1.6 mm (ọkpụrụkpụ 1.6) mmmmmmmm, ma ọ bụghị ya, ọ ga -abawanye ihe isi ike nke egwe ọka na -arụ ọrụ. otu na -adabere na ngwa dị iche iche, oghere nke enweghị oghere dị ihe dị ka usoro usoro 0.5mm enweghị ike ịbụ ihe na -erughị 5mm

Ii. Okwu ndị dị mkpa chọrọ nlebara anya

1. Akwụkwọ izizi na imewe PADS.

(1) Edebere PADS n’ụdị ọla kọpa, ụlọ ọrụ anyị na -etinye ọla kọpa n’ụdị Hatch. Mgbe ebugharị faịlụ mbụ nke onye ahịa, ekwesịrị idobe ya na ọla maka nchekwa (idebe ọla kọpa) iji zere sekit dị mkpirikpi.

(2) Njirimara ihu na PADS nwere ihu abụọ ka ekwesịrị ịhazi site na, ọ bụghị ParTIal. Enweghi ike iwepụta faịlị, nke na -ebute ipu mmiri.

(3) Etinyekwala oghere a haziri na PADS yana ihe mejupụtara ya, n’ihi na enweghị ike ịmepụta GERBER. Iji zere ịgbapụta oghere, biko tinye oghere na DrillDrawing.

2. Akwụkwọ gbasara imewe PROTEL99SE na DXP

(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) Akpọchila akara contour na Protel99SE. GERBER enweghị ike ịmepụta nke ọma.

(3) Na faịlụ DXP, ahọrọla nhọrọ nchekwa, ọ ga -enyocha ahịrị contour na ihe ndị ọzọ, enweghị ike iwepụta GERBER.

(4) Biko leba anya n’ụdị mma na adịghị mma nke ụdị akwụkwọ abụọ a. Na ụkpụrụ, akwa elu dị mma, ekwesịrị ịhazi okpuru ala ya ka ọ bụrụ nke ọzọ. Ụlọ ọrụ anyị na -eme efere site n’ịkpakọba site n’elu ruo ala. Otu efere pụrụ iche, etinyela uche na uche gị! Ma eleghị anya, ọ bụ n’ụzọ ọzọ

3. Nchedo ndị ọzọ.

(1) Ọdịdị (dị ka okpokoro efere, oghere, V-ebipụ) ga-etinyerịrị na nchekwa nchekwa ma ọ bụ akwa igwe, enweghị ike itinye ya na ọkwa ndị ọzọ, dị ka akwa mbipụta ihuenyo, akwa ahịrị. All slots or holes that need mechanical molding should be placed in one layer as far as possible to avoid leakage.

(2) ọ bụrụ na igwe ihe eji arụ ọrụ na akwa oyi akwa ihu abụọ adịghị ekwekọ, biko mee ntuziaka pụrụ iche, na mgbakwunye na udi ka ọ dị mma, dịka enwere oghere dị n’ime, na mbadamba oghere dị n’ime ya dị n’ụdị dị n’ahịrị. ọ dị mkpa ka ehichapụ akụkụ ahụ, oghere dị n’ime gong na-enweghị mmiri, imewe na akwa igwe yana idebe oghere na oghere na-abụkarị oghere ọla kọpa (mee ihe nkiri igwu ọla kọpa), Ọ bụrụ na ọ dị mkpa ka esichaa ya n’ime oghere ọla, biko kwuo okwu pụrụ iche.

(3) Ọ bụrụ na ịchọrọ ime oghere etinyere n’ụzọ kachasị dị nchebe bụ ịjikọ ọnụ nke ọtụtụ pad, ụzọ a agaghị agahie.

(4) Biko mee ndetu pụrụ iche ma ọ dị mkpa ịme nhazi bevel mgbe ị na -etinye usoro nke efere mkpịsị aka ọla edo.

(5) Biko lelee ma enwere mpe mpe akwa dị na faịlụ GERBER. Na mkpokọta, ụlọ ọrụ anyị ga -emepụta ozugbo dị ka faịlụ GERBER.

(6) Jiri ụdị sọftụwia atọ, biko tinye nlebara anya pụrụ iche ma ọ dị mkpa ka ekpughere ọla kọpa.
