Momwe mungakhazikitsire PCB kuti muphatikizepo PCB mosavuta?

Pofuna kupititsa patsogolo kupanga bwino komanso kuchepetsa mtengo wopangiraMsonkhano wa PCBndondomeko, anabala matabwa dera zambiri kupanga gulu kupanga, zimene zingathandize PCBA processing chomera kuchita Chip kuwotcherera.Otsatirawa adzalankhula za wamba panelized njira ndi mfundo za bolodi dera.

Mfundo ya PCB panelization:

1. Kukula kwa PCB gulu m'lifupi bolodi ≤ 300mm (Fuji mzere);ngati mukufuna kugawa basi, kukula kwa PCB kuyenera ≤ 125mm(W) × 180mm(L).
2. Mawonekedwe a PCB adzakhala pafupi ndi lalikulu momwe ndingathere, ndipo analimbikitsa bolodi splicing ndi (2 * 2, 3 * 3, 4 * 4) gulu lililonse.
3. Chojambula chakunja (clamping m'mphepete) cha board board chidzatengera mapangidwe otsekeka kuti awonetsetse kuti gulu la PCB silidzapunduka pambuyo pokhazikika.
4. The yaing'ono PCB bolodi pakati mtunda adzakhala ankalamulira 75mm ~ 145mm.
5. Sipadzakhala zipangizo zazikulu kapena zipangizo zotulukira pafupi ndi malo olumikizirana pakati pa chimango chakunja cha bolodi la splicing ndi bolodi yaing'ono yamkati, ndipo padzakhala danga lalikulu kuposa 0.5mm pakati pa zigawozo ndi m'mphepete mwa bolodi la PCB. kuonetsetsa ntchito yachibadwa ya chida kudula.
6. Pa ngodya zinayi za chimango chakunja cha PCB, mabowo anayi oyika amatsegulidwa ndi m'mimba mwake (4mm ± 0.01mm);Mphamvu ya dzenje liyenera kukhala laling'ono kuti liwonetsetse kuti silidzasweka panthawi yotsitsa ndi kutsitsa;Kutalika kwa dzenje ndi kulondola kwa malo kudzakhala kwakukulu, ndipo dzenje lidzakhala losalala.
7. Bolodi iliyonse yaing'ono mu PCB iyenera kukhala ndi mabowo osachepera atatu, 3 ≤ dzenje m'mimba mwake ≤ 6mm, ndipo mawaya kapena SMT saloledwa mkati mwa 1mm ya dzenje loyikira m'mphepete.
8. Mukayika malo owonetsera, malo osakanizidwa ndi kuwotcherera 1.5mm okulirapo kuposa malo oikirapo nthawi zambiri amasungidwa mozungulira poyikirapo.
9. Zigawo zazikuluzikulu zidzaperekedwa ndi malo oyika kapena mabowo, monga: maikolofoni, mawonekedwe a batri, microswitch, mawonekedwe a mutu, galimoto, ndi zina zotero.

Njira zodziwika bwino za PCB zolumikizidwa pagulu:

1, V-CUT
V-CUT imatanthawuza kuti matabwa angapo kapena bolodi lomwelo likhoza kuphatikizidwa ndikuphatikizidwa pamodzi, ndiyeno V-groove ikhoza kudulidwa ndi makina a V-CUT pakati pa matabwa pambuyo pa PCB processing, yomwe imatha kusweka panthawi yogwiritsira ntchito.Ndi njira yodziwika kwambiri masiku ano.

2. Kukhomerera poyambira
Kukhomerera kumatanthauza mphero yopanda kanthu pakati pa mbale kapena mbale zamkati zokhala ndi makina ophera monga momwe zimafunikira, zomwe zimafanana ndi kukumba.

3. dzenje la sitampu
Izi zikutanthauza kuti gwiritsani ntchito kabowo kakang'ono kulumikiza bolodi la PCB, lomwe limawoneka ngati mawonekedwe a macheka pa sitampu, motero amatchedwa ulalo wa bowo la sitampu.Ulalo wa dzenje la sitampu umafunikira kuwongolera kwakukulu kuzungulira bolodi, komwe ndi bowo la sitampu lomwe lingagwiritsidwe ntchito m'malo mwa mzere wa V.
