Kazhinji, PCB inoshandisa V-CUTs. Makomba echitambi anowanzo shandiswa pakubata nemabhodhi asina kujairika kana denderedzwa. Matampu hole mabhiriji anobatanidza mabhodhi (kana mabhodhi asina chinhu) kunyanya kupa rubatsiro, kuve nechokwadi chekuti mabhodhi haaparadzanise panguva yekugadziriswa. Izvi zvakare zvinodzivirira kudonha kwe mold panguva yekuumbwa. Makomba echitambi anonyanya kushandiswa kugadzira akazvimirira PCB modules, seWi-Fi, Bluetooth, kana core board modules, inogona kushandiswa sezvikamu zvakazvimirira zvakaiswa pane imwe PCB panguva yegungano.
Bridge Distance uye Kufara
- The mwero zambuko upamhi zvakajairika 1.6 mamirimita (kunze kwekunge zvataurwa neimwe nzira nemutengi).
- Kana mupendero wakareba webhodhi uri ≤ 100 mm kana ukobvu hwebhodhi hunopfuura 1.6 mm, hupamhi hwebhiriji hunogona kudzikiswa kusvika 0.8 mamirimita.
- Mabhiriji anofanira kuparadzaniswa 70 mm kureba (kana nzvimbo pakati pemabhiriji isingasviki 70 mm, hupamhi hwebhiriji hunogona kudzikiswa kusvika 0.5 mamirimita).
- Tevedzera nheyo iyo mapuranga matete anoda mabhiriji akafara kudzivirira kuputsika panguva yekugadzirisa.
Stamp Hole Dhizaini
- Saizi dzemaburi echitambi kazhinji vari pakati 0.3 - 0.8 mm (kunze kwekunge zvataurwa neimwe nzira nemutengi).
- The mwero gomba dhayamita is 0.5 mamirimita, ine imwe nzvimbo yekubatanidza yakagadzirwa yega yega 70 mamirimita.
- Kune mamwe madhayamita echitambi, onai kuti chinhambwe chiri pakati pemakomba uye huwandu hwemakomba ezvitambi zvinotevedza nzvimbo shoma 0.5 mamirimita.
- Paunenge uchigadzira, koshesa recessed configurations, apo 2/3 yedhiyamita yegomba rechitambi iri mukati meiyo yakapedzwa bhodhi yuniti, ichive nechokwadi chakakodzera nzvimbo pakati pemakomba, mitsetse, uye zvimwe zvikamu.
Stamp Hole Bridges + V-CUT
- Apo zvose zvitambi mugomba mabhiriji uye V-CUT magadzirirwo aripo panzvimbo imwe chete, zvinokurudzirwa kushandisa chete iyo V-CUT dhizaini.
- Kune nzvimbo dzine mbiri mabhiriji uye V-CUTs (pasina maburi echitambi), the zambuko upamhi hunofanira kuva ≥ 3.0 mm.
Peripheral Half-Hole Mabhodhi ane Matampu Makomba
- For mapuranga ane hafu-gomba ane solder spray, mabhiriji ane masitampu maburi anofanirwa kudonhedzwa mushure meiyo solder spray process kudzivirira bhodhi kubva pakutyoka panguva ye soldering.
- Saizi yemabhiriji ebhodhi rehafu-gomba inoteedzera zvakajairwa zvigadziro zvemaburi echitambi.
- Kana hupamhi hwebhiriji mushure mekugaya hafu-gomba iri ≤ 1.0 mm, maburi echitambi haadiwi.
- Gomba rimwe rechitambi rinogona kuwedzerwa kune upamhi hwebhiriji pakati pe1.0 mm ne1.5 mm.
Zvinyorwa Zvakakosha
- Pamapoinzi ekubatanidza akagadzirwa nevatengi, tevedzera zviri pamusoro apa pese pazvinogoneka. Kana nzvimbo ichibvumira, wedzera rimwe kana maviri mamwe mabhiriji mapoka.
- Kana mutengi-akagadzirwa ekubatanidza mapoinzi akasasangana nemirairo iri pamusoro, bvunza mutengi uye kurudzira kugadzira patsva mapoinzi ekubatanidza zvinoenderana neizvi zvakatemwa.
- Kana mutengi akaramba kugadzirisa dhizaini, a process review zvinofanira kuitwa.
Iyi nzira inovimbisa kutendeseka kwechimiro, nyore kugadzirisa, uye kuvimbika panguva yekusangana kwePCB.
