Mamwe mapfundo ekutanga ekucherechedza kana uchigadzira Pcb bhodhi:

I. Tsananguro yakadzama yeanoenderana pcb dhizaini parameter

1. Mutsara

(1) Minimum mutsara upamhi: 6mil (0.153mm). Ndokureva kuti, kana iyo tambo yakafara isingasviki 6mil, haizokwanise kuburitsa. Kana mamiriro ekugadzirwa achibvumidza, iyo yakakura dhizaini, iri nani hupamhi hwemutsara, zvirinani kugadzirwa kwefekitori, goho rakakwirira. Iyo general dhizaini musangano yakatenderedza 10mil, iyi poindi yakakosha kwazvo, inofanirwa kutariswa mukugadzirwa.

(2) Minimum mutsara spacing: 6mil (0.153mm). Minimum line daro, ndiko kuti, tambo kuenda kumutsara, tambo kune padhi daro haisi pasi pe6mil kubva kune yekugadzira nzvimbo yekutarisa, iyo yakakura iri nani, general general mu10mil, hongu, mamiriro ekugadzirwa, akakura zviri nani izvi poindi yakakosha kwazvo, inofanirwa kutariswa mukugadzirwa.

(3) Kureba kubva pamutsara kuenda kumutsara mutsara 0.508mm (20mil)

2.Nzira yegomba (inowanzozivikanwa seyakagundika gomba)

(1) Minimum aperture: 0.3mm (12mil)

(2) Iyo shoma kuburikidza nepaburi (VIA) kuzarura haifanire kunge iri pasi pe0.3mm (12mil), padhi unilateral harifanirwe kunge riri pasi pe6mil (0.153mm), zviri nani kupfuura 8mil (0.2mm) haina kuganhurirwa (ona Mufananidzo 3 ) iyi poindi yakakosha kwazvo, inofanirwa kutariswa mukugadzirwa

(3) kuburikidza neburi (VIA) gomba kugomba nzvimbo (gomba kudivi kune rimwe divi) harifanirwe kunge riri pasi pe: 6mil zvirinani kupfuura 8mil iyi poindi yakakosha, inofanirwa kutariswa mukugadzirwa

(4) Kureba pakati pepad uye contour mutsetse 0.508mm (20mil)

(5) a. Hole kumutsara kutsemura:

NPTH (isina Welding ring): gomba muripo 0.15mm kumashure kure mutsara kupfuura 0.2mm

PTH (ine rin’i yekunamatira): gomba muripo 0.15mm uye pamusoro penzvimbo yekureba 0.3mm

Spole-kusvika-mugomba kutsemura:

PTH (ine welded ring): 0.15mm mushure megomba muripo kune 0.45mm kana kupfuura

NPTH mugomba: 0.15mm kusvika 0.2mm mushure mugomba muripo

VIA: Iyo nzvimbo inogona kunge iri diki zvishoma

3. PAD PAD (inowanzozivikanwa se plug plug (PTH))

(1) Saizi yegomba re plug rinoenderana nechinhu chako, asi chinofanira kunge chakakura kudarika pini yako yechinhu. Zvinokurudzirwa kuti pini yepulagi ive hombe kupfuura 0.2mm, ndiko kuti, 0.6 yepini yechinhu, unofanirwa kuigadzira se0.8 zvirinani, kuitira kudzivirira kushivirira kwemuchina kunokonzerwa nekupinza kwakaoma.

(2) Plug hole (PTH) yekunze mhete unilateral divi haifanire kunge iri pasi pe0.2mm (8mil), hongu, iyo yakakura iri nani (sezvakaratidzwa muMufananidzo 2) iyi poindi yakakosha, dhizaini inofanirwa kutariswa

(3) Plug hole (PTH) gomba kuburi spacing (gomba kumucheto kune gomba kumucheto) haifanire kunge iri pasi pe: 0.3mm hongu, yakakura zvirinani (sezvakaratidzwa muFIG. 3) Iyi poindi yakakosha, inofanira inofungidzirwa mukugadzirwa

(4) Kureba pakati pepad uye contour mutsetse 0.508mm (20mil)

4. Welding

(1) Plug-in gomba hwindo kuvhura, SMD hwindo rekuvhura divi harifanire kunge riri pasi pe 0.1mm (4mil)

5. Hunhu (dhizaini yemavara inokanganisa kugadzirwa, uye kujekesa kwemavara kwakabatana zvikuru nekugadzirwa kwevatambi)

(1) hunhu hweizwi hupamhi haugone kudzika pane 0.153mm (6mil), izwi rekuti kukwirira harigone kudarika 0.811mm (32mil), iyo upamhi reshiyo kusvika pakukwirira reshiyo yehukama hwakanakisisa ndeye 5 kureva, izwi upamhi 0.2mm izwi kukwirira i1mm, kuitira Push kirasi

6. Iyo shoma nzvimbo yekusiyana-kwesimbi grooves haifanire kunge iri pasi pe1.6mm, zvikasadaro ichawedzera zvakanyanya kuoma kwekumucheto kugaya (Mufananidzo 4)

7. Pazera

. zvakafanana zvichienderana nemidziyo yakasiyana, iyo gap isina gap collage ingangoita 1mm maitiro ekumusoro haigone kuve pasi pe1.6mm

Ii. Nyaya dzakakosha dzinoda kutariswa

1. Gwaro rekutanga paPADS dhizaini.

(1) MAPADHA akaiswa mumhangura modhi, uye kambani yedu inoisa mhangura muHatch modhi. Mushure mekunge mafaera ekutanga emutengi afambiswa, anofanirwa kuiswazve nemhangura kuti ichengetedzwe (Mafashama achiisa mhangura) kudzivirira dunhu pfupi.

(2) Meso zvivakwa mune mbiri-mapaneru PADS inofanirwa kumisikidzwa kuKubva, kwete ParTIal. Kuchera mafaera hakugone kugadzirwa, zvichikonzera kuchera kuvuza.

(3) Usawedzere maburi akagadzirwa muPADS pamwe nezvinhu, nekuti GERBER haigone kugadzirwa. Kuti udzivise slot kuburitsa, ndapota wedzera mabiko mu DrillDrawing.

2. Zvinyorwa nezve PROTEL99SE uye DXP dhizaini

(1) Yedu yekambani Solder mask dura iri pasi peSolder mask layer. Kana iyo Paste dura ichida kugadzirwa, uye iyo Solder hwindo rine akawanda marara haigone kuburitsa GERBER, ndokumbira utamire kune Solder rukoko.

(2) Usavhara iyo contour tambo muProtel99SE. GERBER haigone kugadzirwa zvakajairika.

(3) Mune iyo DXP faira, usasarudze KEEPOUT sarudzo, ichaongorora iyo contour tambo uye zvimwe zvinhu, isingakwanise kuburitsa GERBER.

(4) Ndokumbira utarise kune yakanaka uye yakaipa dhizaini yemhando mbiri idzi dzemagwaro. Mukutaura, iyo yepamusoro yepamusoro yakanaka, uye yepasi dhizaini inofanira kugadzirwa seinodzosera kumashure. Kambani yedu inogadzira maplate nekukanda kubva kumusoro kusvika pasi. Imwe ndiro yakasarudzika, usatarise paunoda! Pamwe ndiyo imwe nzira yakatenderedza

3. Dzimwe nzira dzekuzvidzivirira nadzo.

(1) Chimiro (senge ndiro furemu, slot, V-kutemwa) inofanirwa kuiswa muKUDZIDZIRA dura kana mechina dhizaini, haigone kuiswa mune mamwe matanda, senge skrini yekudhinda dhizaini. Nzvimbo dzese dzinotsvedza kana makomba anoda michina kuumbwa anofanirwa kuiswa mune imwe nhanho kusvika pazvinogona kudzivirira kuvuza.

(2) kana meyitara nhete uye KUSVIRA pakapetwa matanda maviri ekuonekwa asingaenderane, ndapota ita mirayiridzo yakakosha, pamusoro pechimiro kune chimiro chinoshanda, senge pane groove yemukati, uye iyo yemukati groove mharadzano yeplate ndiro yekunze chimiro chetambo. chidimbu chinoda kubviswa, chisina kubvaruka gong yemukati groove, dhizaini mune yemuchina diki uye KEEPOUT dura gomba uye gomba rinowanzo gadzirwa nemhangura gomba (ita firimu kuchera mhangura), Kana ichida kugadziriswa mumakomba esimbi, ndapota ita mazwi akakosha.

(3) Kana iwe uchida kuita iyo yakagadziriswa simbi nzira yakachengeteka kwazvo ndeyekuisa pamwechete huwandu hwepadhi, iyi nzira haifanire kukanganisa

(4) Ndokumbirawo muite chinyorwa chakakosha kana zvichidikanwa kuti mugadzirise bevel kana muchiisa odha yegoridhe chigunwe ndiro.

(5) Ndokumbira utarise kana paine mashoma masara mune iyo GERBER faira. Kazhinji, kambani yedu inozogadzira zvakananga maererano nefaira reGERBER.

(6) Shandisa matatu marudzi esoftware dhizaini, ndapota nyatsoteerera kuti chinzvimbo chakakosha chinoda kufumura mhangura.
