Nguvu PCB layer and protel similarities and differences

Miundo yetu mingi hutumia programu zaidi ya moja. Kwa sababu protel ni rahisi kuanza, marafiki wengi hujifunza protel kwanza na kisha Power. Kwa kweli, wengi wao hujifunza Nguvu moja kwa moja, na wengine hutumia programu mbili pamoja. Since the two software have some differences in layer Settings, beginners can easily get confused, so let’s compare them side by side. Wale ambao husoma nguvu moja kwa moja pia wanaweza kuiangalia ili kuwa na kumbukumbu.

First look at the classification structure of the inner layer

Jina la programu Sambaza Matumizi ya jina la Tabaka

PROTEL: Positive MIDLAYER Pure line layer

MIDLAYER Hybrid electrical layer (including wiring, large copper skin)

Hasi hasi (bila mgawanyiko, mfano GND)

INTERNAL Strip INTERNAL division (most common multi-power situation)

NGUVU: chanya NO NDEGE Safu laini laini

NO PLANE Mixed electrical layer (use the method of COPPER POUR)

SPLIT / mchanganyiko wa safu ya umeme (safu ya ndani njia ya safu ya SPLIT)

Filamu hasi hasi (bila kizigeu, mfano GND)

Kama inavyoonekana kutoka kwa takwimu hapo juu, tabaka za umeme za POWER na PROTEL zinaweza kugawanywa katika mali nzuri na hasi, lakini aina za safu zilizo katika sifa hizi mbili za safu ni tofauti.

1.PROTEL has only two layer types, corresponding to positive and negative attributes respectively. Walakini, NGUVU ni tofauti. Filamu nzuri katika POWER zimegawanywa katika aina mbili, HAPANA NDEGE na MPASUKO / MCHANGANYIKO

2. Negative films in PROTEL can be segmented by internal electric layer, while negative films in POWER can only be pure negative films (internal electric layer cannot be segmented, which is inferior to PROTEL). Inner segmentation must be done using positive. Ukiwa na safu ya SPLIT / MIXED, unaweza pia kutumia chanya ya kawaida (HAPANA NDEGE) + shaba.

That is to say, in POWER PCB, whether used for POWER inner layer segmentation or MIXED electrical layer, must use positive, and ordinary positive (NO PLANE) and special MIXED electrical layer (SPLIT/MIXED) the only difference is the way of laying copper is not the same! Hasi inaweza kuwa hasi moja tu. (Haipendekezi kutumia 2D LINE kugawanya filamu hasi kwa sababu inakabiliwa na makosa kwa sababu ya ukosefu wa unganisho la mtandao na sheria za muundo.)

These are the main differences between layer Settings and inner splits.

Tofauti kati ya safu ya ndani ya SPLIT / MIXED safu ya ndani ya SPLIT na safu ya NDEGE haina shaba

1.SPLIT/MIXED: the PLACE AREA command must be used, which can automatically remove the inner independent pad and can be used for wiring. Other networks can be easily segmented on the large copper skin.

2.NO PLANEC layer: COPPER POUR must be used, which is the same as the outer line. Independent pads will not be automatically removed. Hiyo ni kusema, hali ya ngozi kubwa ya shaba inayozunguka ngozi ndogo ya shaba haiwezi kutokea.

Mpangilio wa safu ya POWER PCB na njia ya kugawanya safu ya ndani

After looking at the structure diagram above, you should have a good idea of the layer structure of POWER. Now that you have decided what layer to use to complete the design, the next step is to add an electrical layer.

Chukua bodi ya safu nne kama mfano:

First, create a new design, import the netlist, complete the basic layout, and then add the LAYER setup-Layer DEFINITION. In the ELECTRICAL LAYER area, click MODIFY, and enter 4, OK, OK in the popup window. Now you have two new electrical layers between TOP and BOT. Name the two layers and set the layer type.

INYER LAYER2 iipe jina GND na uweke kwa CAM NDEGE. Kisha bonyeza upande wa kulia wa ASSIGN mtandao. Safu hii ni ngozi nzima ya shaba ya filamu hasi, kwa hivyo ASSIGN moja GND.

Taja NGUVU YA NDANI YA LAYER3 na uiweke kwa SPLIT / MIXED (kwa sababu kuna vikundi vingi vya usambazaji wa POWER, kwa hivyo INPL INGER itatumiwa), bonyeza ASSIGN na ASSIGN mtandao wa NGUVU ambao unahitaji kupitia safu ya INNER kwenye dirisha lililounganishwa upande wa kulia (kudhani mitandao mitatu ya usambazaji wa NGUVU imetengwa).

The next step for wiring, the outer line in addition to the power supply outside all go. Mtandao wa POWER umeunganishwa moja kwa moja na safu ya ndani ya shimo inaweza kushikamana kiatomati (ujuzi mdogo, kwanza fafanua kwa muda aina ya safu ya POWER CAM NDEGE, ili zote zilizotengwa kwa safu ya ndani ya mtandao wa POWER na mfumo wa laini ya shimo utafikiria ambayo imeunganishwa, na ghairi moja kwa moja laini ya panya). Baada ya wiring yote kukamilika, safu ya ndani inaweza kugawanywa.

Hatua ya kwanza ni kupaka rangi mtandao ili kutofautisha maeneo ya anwani. Bonyeza CTRL + SHIFT + N kubainisha rangi ya mtandao (imeachwa).

Kisha badilisha mali ya safu ya safu ya POWER kurudi kwa CHANGANYA / MCHANGANYIKO, bonyeza ENEO LA KUCHORA-MAHALI, kisha chora shaba ya mtandao wa kwanza wa NGUVU.

Mtandao 1 (manjano): Mtandao wa kwanza unapaswa kufunika bodi nzima na kuteuliwa kama mtandao wenye eneo kubwa zaidi la unganisho na idadi kubwa ya viunganisho.

Mtandao # 2 (kijani kibichi): Sasa kwa mtandao wa pili, kumbuka kuwa kwa kuwa mtandao huu uko katikati ya bodi, tutakata mtandao mpya kwenye uso mkubwa wa shaba ambao tayari umewekwa. Or click on PLACE AREA, and then follow the instructions of the color rendering of cutting AREA, when double click finish cutting, the system will automatically appear cut by a current network (1) and (2) the AREA of the current network isolation line (because it is made cutting feature pave the way of copper, so can’t like cutting negative with a positive line to complete large copper surface segmentation). Toa jina la mtandao pia.

Network 3 (red) : the third network below, since this network is closer to the board edge, we can also use another command to do it. Bonyeza mtaalamu -AUTO NDEGE IKITENGANISHA, chora kuchora kutoka ukingo wa bodi, funika anwani zinazohitajika kisha urudi kwenye ukingo wa bodi, bonyeza mara mbili kukamilisha. Ukanda wa kujitenga pia utaonekana kiatomati na dirisha la ugawaji wa mtandao litaibuka. Kumbuka kuwa dirisha hili linahitaji mitandao miwili itengwe mfululizo, moja kwa mtandao ambao umekata tu na moja kwa eneo lililobaki (limeangaziwa).

Kwa wakati huu, kazi nzima ya wiring imekamilika kimsingi. Mwishowe, POUR meneja-ndege CONNECT hutumiwa kujaza shaba, na athari inaweza kuonekana.
