Graphitization ndi electroplating pamabowo kapena mabowo m'mphepete mwa PCB.Dulani m'mphepete mwa bolodi kuti mupange mabowo angapo.Mabowo awa ndi omwe timawatcha kuti stamp hole pads.

1. Kuipa kwa mabowo a sitampu

①: Bololo litapatulidwa, limakhala ndi mawonekedwe ngati macheka.Anthu ena amachitcha mawonekedwe a dzino la galu.N'zosavuta kulowa mu chipolopolo ndipo nthawi zina amafunika kudulidwa ndi lumo.Choncho, popanga mapangidwe, malo ayenera kusungidwa, ndipo bolodi nthawi zambiri imachepetsedwa.

②: Onjezani mtengo.Bowo la sitampu locheperako ndi dzenje la 1.0MM, ndiye kukula kwa 1MM uku kumawerengedwa pa bolodi.

2. Udindo wa mabowo wamba wa sitampu

Nthawi zambiri, PCB ndi V-CUT.Ngati mukukumana ndi bolodi lapadera kapena lozungulira, ndizotheka kugwiritsa ntchito dzenje la sitampu.Bolodi ndi bolodi (kapena bolodi lopanda kanthu) zimagwirizanitsidwa ndi mabowo a sitampu, omwe makamaka amathandizira, ndipo bolodi silidzamwazika.Ngati nkhungu itatsegulidwa, nkhunguyo siigwa..Nthawi zambiri, amagwiritsidwa ntchito popanga ma module a PCB okha, monga Wi-Fi, Bluetooth, kapena ma module a board, omwe amagwiritsidwa ntchito ngati zigawo zodziyimira zokha kuyikidwa pa bolodi lina pa msonkhano wa PCB.

3. Kutalikirana kwa mabowo a sitampu

0.55mm ~ 3.0mm (malingana ndi mmene zinthu zilili, ambiri ntchito 1.0mm, 1.27mm)

Kodi mabowo a sitampu ndi ati?

1. Theka dzenje

1. Bowo laling'ono lokhala ndi theka la hol

1. Mabowo ozungulira m'mphepete mwa bolodi

4. Zofunikira za bowo la sitampu

Malingana ndi zosowa ndi kutha kwa bolodi, pali zina zomwe zimapangidwira zomwe ziyenera kukumana.Mwachitsanzo:

①Kukula: Ndikofunikira kugwiritsa ntchito kukula kwakukulu kotheka.

② Chithandizo chapamwamba: Zimatengera kutha kwa bolodi, koma ENIG ikulimbikitsidwa.

③ Mapangidwe a OL pad: Ndikoyenera kugwiritsa ntchito OL pad yayikulu kwambiri pamwamba ndi pansi.

④ Chiwerengero cha mabowo: Zimatengera kapangidwe kake;komabe, zimadziwika kuti ang'onoang'ono chiwerengero cha mabowo, zovuta kwambiri PCB msonkhano ndondomeko.

Bowo lokutidwa ndi theka likupezeka pa PCB wamba komanso zapamwamba.Pamapangidwe a PCB wamba, kutalika kocheperako kwa dzenje lokhala ngati c ndi 1.2 mm.Ngati mukufuna mabowo ang'onoang'ono ooneka ngati c, mtunda wochepera pakati pa mabowo awiri otidwa ndi theka ndi 0,55 mm.

Njira Yopangira Sitampu Hole:

Choyamba, pangani zonse zokutidwa ndi dzenje monga mwachizolowezi pamphepete mwa bolodi.Kenako gwiritsani ntchito mphero kuti mudulire dzenjelo pakati pamodzi ndi mkuwa.Popeza kuti mkuwa ndi wovuta kugaya ndipo ukhoza kuchititsa kuti chibowolocho chisweke, gwiritsani ntchito pobowola kwambiri mothamanga kwambiri.Izi zimapangitsa kuti pakhale malo osalala.Bowo lililonse limawunikiridwa pamalo opatulira ndikuchotsedwa ngati kuli kofunikira.Izi zipanga dzenje la sitampu lomwe tikufuna.
