Kuchengetedzwa kwemagetsi kureba

1. Kupatsanurana pakati pewaya
Zvinoenderana nehukuru hwekugadzira hwevagadziri vePCB, chinhambwe chiri pakati pematanho nematehwe hachifanirwe kunge chiri pasi pe4 mil. Mutsetse wepakati wemutsara ndiwo zvakare mutsara-ku-mutsetse uye mutsara-kune-pedhi. Zvakanaka, kubva pakuona kwedu kwekugadzira, hongu, iyo yakakura zviri nani pasi pemamiriro ezvinhu. Iyo general 10 mil ndiyo yakawanda.

2. Padhi aperture uye padhi pahupamhi:
Sekureva kwemugadziri wePCB, iyo dhayamita yegomba repadhi haisi pasi pe 0.2 mm kana yakadhiriwa nemichina, uye haisi pasi pe 4 mil kana yakacherwa laser. The aperture tolerance yakasiyana zvishoma zvichienderana neplate. Kazhinji inogona kudzorwa mukati me 0.05 mm. Iyo hupamhi hudiki hwepadhi haifaniri kunge iri pasi pe 0.2 mm.

3. Chinhambwe chiri pakati pepedhi nepedhi:
Zvinoenderana nekugadzirisa kugona kwevagadziri vePCB, chinhambwe chiri pakati pemapadhi nemapadhi hachifanirwe kunge chiri pasi pe0.2 mm.

4. Chinhambwe pakati peganda rendarira nemupendero webhodhi:
Nharaunda pakati peganda remhangura yakachajiswa uye kumucheto kwePCB board zviri nani kwete isingasviki 0.3 mm. Kana mhangura yakaiswa panzvimbo yakakura, inowanzodikanwa kuti ive ne shrinkage chinhambwe kubva kumucheto kwebhodhi, iyo inowanzoiswa ku20 mil. Kazhinji, nekuda kwekutariswa kwemakina kwebhodhi redunhu rakapedzwa, kana kudzivirira mukana wekupeta kana magetsi mapfupi edunhu anokonzerwa netambo yemhangura yakafumurwa pamucheto webhodhi, mainjiniya anowanzo dzikisa mabhuroko makuru emhangura ne20 mil hukama kumucheto kwebhodhi. Ganda remhangura harisi nguva dzose rinopararira kumucheto webhodhi. Kune nzira dzakawanda dzekutarisana nemhangura iyi shrinkage. Semuenzaniso, dhirowa dhizaini yekuchengeta pamucheto webhodhi, wobva waisa chinhambwe pakati pemhangura nekuchengetedza.

Isiri yemagetsi kuchengetedzwa kure

1. Hunhu hwakafara nekureba nepakati:
Nezve mavara esiriki skrini, isu tinowanzo shandisa tsika dzakajairwa senge 5/30 6/36 MIL, nezvimwe. Nekuti kana iwo manyoro ari madiki, kugadzirisa uye kudhinda kuchasvibiswa.

2. Chinhambwe kubva pasiki skrini kuenda padhi:
Kudhinda sikirini hakubvumidze mapedhi. Kana chidzitiro chesilika chakafukidzwa nemapedhi, tini haizove yakasungirirwa kana ichitengeswa, iyo inokanganisa kuiswa kwezvikamu. General board vagadziri vanoda 8 mil spacing kuti ichengetwe. Kana zvirizvo nekuti nzvimbo yemamwe mabhodhi ePCB iri padyo, nzvimbo ye4MIL haigamuchirwi. Zvino, kana sirika sikirini yakavhara netsaona padhi panguva yekugadzira, mugadziri webhodhi anozobvisa otomatiki chikamu chesiriki chesikirini chakasiiwa padhi panguva yekugadzira kuti ive nechokwadi cherata padhi. Saka tinofanira kuteerera.

3. 3D kureba uye yakatwasuka spacing pane mechaniki chimiro:
Paunenge uchiisa zvishandiso paPCB, zvinodikanwa kuti utarise kana iyo yakachinjika kutungamira uye kureba kwenzvimbo kuchapokana nezvimwe zvimiro zvemuchina. Naizvozvo, kana uchigadzira, zvinodikanwa kuti utarise zvizere kuchinjika kwechimiro chepakati pakati pezvikamu, pamwe nepakati pePCB chigadzirwa uye goko rechigadzirwa, uye kuchengetedza chinhambwe chakachengeteka kune chimwe nechimwe chinotarirwa chinhu.
